128 DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.
132 See L<DBIx::Class::Schema::Loader>.
136 This is the base class for the storage-specific C<DBIx::Class::Schema::*>
137 classes, and implements the common functionality between them.
139 =head1 CONSTRUCTOR OPTIONS
141 These constructor options are the base options for
142 L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are:
144 =head2 skip_relationships
146 Skip setting up relationships. The default is to attempt the loading
149 =head2 skip_load_external
151 Skip loading of other classes in @INC. The default is to merge all other classes
152 with the same name found in @INC into the schema file we are creating.
156 Static schemas (ones dumped to disk) will, by default, use the new-style
157 relationship names and singularized Results, unless you're overwriting an
158 existing dump made by an older version of L<DBIx::Class::Schema::Loader>, in
159 which case the backward compatible RelBuilder will be activated, and the
160 appropriate monikerization used.
166 will disable the backward-compatible RelBuilder and use
167 the new-style relationship names along with singularized Results, even when
168 overwriting a dump made with an earlier version.
170 The option also takes a hashref:
173 relationships => 'v8',
175 column_accessors => 'v8',
181 naming => { ALL => 'v8', force_ascii => 1 }
189 Set L</relationships>, L</monikers> and L</column_accessors> to the specified
194 How to name relationship accessors.
198 How to name Result classes.
200 =item column_accessors
202 How to name column accessors in Result classes.
206 For L</v8> mode and later, uses L<String::ToIdentifier::EN> instead of
207 L<String::ToIdentifier::EM::Unicode> to force monikers and other identifiers to
218 Latest style, whatever that happens to be.
222 Unsingularlized monikers, C<has_many> only relationships with no _id stripping.
226 Monikers singularized as whole words, C<might_have> relationships for FKs on
227 C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships.
229 Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for
234 All monikers and relationships are inflected using
235 L<Lingua::EN::Inflect::Phrase>, and there is more aggressive C<_id> stripping
236 from relationship names.
238 In general, there is very little difference between v5 and v6 schemas.
242 This mode is identical to C<v6> mode, except that monikerization of CamelCase
243 table names is also done correctly.
245 CamelCase column names in case-preserving mode will also be handled correctly
246 for relationship name inflection. See L</preserve_case>.
248 In this mode, CamelCase L</column_accessors> are normalized based on case
249 transition instead of just being lowercased, so C<FooId> becomes C<foo_id>.
251 If you don't have any CamelCase table or column names, you can upgrade without
252 breaking any of your code.
258 The default mode is L</v7>, to get L</v8> mode, you have to specify it in
259 L</naming> explictly until C<0.08> comes out.
261 L</monikers> and L</column_accessors> are created using
262 L<String::ToIdentifier::EN::Unicode> or L<String::ToIdentifier::EN> if
263 L</force_ascii> is set; this is only significant for names with non-C<\w>
264 characters such as C<.>.
266 CamelCase identifiers with words in all caps, e.g. C<VLANValidID> are supported
267 correctly in this mode.
269 For relationships, belongs_to accessors are made from column names by stripping
270 postfixes other than C<_id> as well, for example just C<Id>, C<_?ref>, C<_?cd>,
271 C<_?code> and C<_?num>, case insensitively.
275 For L</monikers>, this option does not inflect the table names but makes
276 monikers based on the actual name. For L</column_accessors> this option does
277 not normalize CamelCase column names to lowercase column accessors, but makes
278 accessors that are the same names as the columns (with any non-\w chars
279 replaced with underscores.)
283 For L</monikers>, singularizes the names using the most current inflector. This
284 is the same as setting the option to L</current>.
288 For L</monikers>, pluralizes the names, using the most current inflector.
292 Dynamic schemas will always default to the 0.04XXX relationship names and won't
293 singularize Results for backward compatibility, to activate the new RelBuilder
294 and singularization put this in your C<Schema.pm> file:
296 __PACKAGE__->naming('current');
298 Or if you prefer to use 0.07XXX features but insure that nothing breaks in the
299 next major version upgrade:
301 __PACKAGE__->naming('v7');
305 If true, will not print the usual C<Dumping manual schema ... Schema dump
306 completed.> messages. Does not affect warnings (except for warnings related to
307 L</really_erase_my_files>.)
311 By default POD will be generated for columns and relationships, using database
312 metadata for the text if available and supported.
314 Comment metadata can be stored in two ways.
316 The first is that you can create two tables named C<table_comments> and
317 C<column_comments> respectively. These tables must exist in the same database
318 and schema as the tables they describe. They both need to have columns named
319 C<table_name> and C<comment_text>. The second one needs to have a column named
320 C<column_name>. Then data stored in these tables will be used as a source of
321 metadata about tables and comments.
323 (If you wish you can change the name of these tables with the parameters
324 L</table_comments_table> and L</column_comments_table>.)
326 As a fallback you can use built-in commenting mechanisms. Currently this is
327 only supported for PostgreSQL, Oracle and MySQL. To create comments in
328 PostgreSQL you add statements of the form C<COMMENT ON TABLE some_table IS
329 '...'>, the same syntax is used in Oracle. To create comments in MySQL you add
330 C<COMMENT '...'> to the end of the column or table definition. Note that MySQL
331 restricts the length of comments, and also does not handle complex Unicode
334 Set this to C<0> to turn off all POD generation.
336 =head2 pod_comment_mode
338 Controls where table comments appear in the generated POD. Smaller table
339 comments are appended to the C<NAME> section of the documentation, and larger
340 ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION>
341 section to be generated with the comment always, only use C<NAME>, or choose
342 the length threshold at which the comment is forced into the description.
348 Use C<NAME> section only.
352 Force C<DESCRIPTION> always.
356 Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the
361 =head2 pod_comment_spillover_length
363 When pod_comment_mode is set to C<auto>, this is the length of the comment at
364 which it will be forced into a separate description section.
368 =head2 table_comments_table
370 The table to look for comments about tables in. By default C<table_comments>.
371 See L</generate_pod> for details.
373 This must not be a fully qualified name, the table will be looked for in the
374 same database and schema as the table whose comment is being retrieved.
376 =head2 column_comments_table
378 The table to look for comments about columns in. By default C<column_comments>.
379 See L</generate_pod> for details.
381 This must not be a fully qualified name, the table will be looked for in the
382 same database and schema as the table/column whose comment is being retrieved.
384 =head2 relationship_attrs
386 Hashref of attributes to pass to each generated relationship, listed
387 by type. Also supports relationship type 'all', containing options to
388 pass to all generated relationships. Attributes set for more specific
389 relationship types override those set in 'all'.
393 relationship_attrs => {
394 belongs_to => { is_deferrable => 0 },
397 use this to turn off DEFERRABLE on your foreign key constraints.
401 If set to true, each constructive L<DBIx::Class> statement the loader
402 decides to execute will be C<warn>-ed before execution.
406 Set the name of the schema to load (schema in the sense that your database
409 Can be set to an arrayref of schema names for multiple schemas, or the special
410 value C<%> for all schemas.
412 For MSSQL, Sybase ASE, and Informix can be set to a hashref of databases as
413 keys and arrays of owners as values, set to the value:
417 for all owners in all databases.
419 You may need to control naming of monikers with L</moniker_parts> if you have
420 name clashes for tables in different schemas/databases.
424 The database table names are represented by the
425 L<DBIx::Class::Schema::Loader::Table> class in the loader, the
426 L<DBIx::Class::Schema::Loader::Table::Sybase> class for Sybase ASE and
427 L<DBIx::Class::Schema::Loader::Table::Informix> for Informix.
429 Monikers are created normally based on just the
430 L<name|DBIx::Class::Schema::Loader::DBObject/name> property, corresponding to
431 the table name, but can consist of other parts of the fully qualified name of
434 The L</moniker_parts> option is an arrayref of methods on the table class
435 corresponding to parts of the fully qualified table name, defaulting to
436 C<['name']>, in the order those parts are used to create the moniker name.
438 The C<'name'> entry B<must> be present.
440 Below is a table of supported databases and possible L</moniker_parts>.
444 =item * DB2, Firebird, mysql, Oracle, Pg, SQLAnywhere, SQLite, MS Access
448 =item * Informix, MSSQL, Sybase ASE
450 C<database>, C<schema>, C<name>
456 Only load tables matching regex. Best specified as a qr// regex.
460 Exclude tables matching regex. Best specified as a qr// regex.
464 Overrides the default table name to moniker translation. Can be either
465 a hashref of table keys and moniker values, or a coderef for a translator
466 function taking a single scalar table name argument and returning
467 a scalar moniker. If the hash entry does not exist, or the function
468 returns a false value, the code falls back to default behavior
471 The default behavior is to split on case transition and non-alphanumeric
472 boundaries, singularize the resulting phrase, then join the titlecased words
475 Table Name | Moniker Name
476 ---------------------------------
478 luser_group | LuserGroup
479 luser-opts | LuserOpt
480 stations_visited | StationVisited
481 routeChange | RouteChange
483 =head2 col_accessor_map
485 Same as moniker_map, but for column accessor names. If a coderef is
486 passed, the code is called with arguments of
488 the name of the column in the underlying database,
489 default accessor name that DBICSL would ordinarily give this column,
491 table_class => name of the DBIC class we are building,
492 table_moniker => calculated moniker for this table (after moniker_map if present),
493 table_name => name of the database table,
494 full_table_name => schema-qualified name of the database table (RDBMS specific),
495 schema_class => name of the schema class we are building,
496 column_info => hashref of column info (data_type, is_nullable, etc),
501 Similar in idea to moniker_map, but different in the details. It can be
502 a hashref or a code ref.
504 If it is a hashref, keys can be either the default relationship name, or the
505 moniker. The keys that are the default relationship name should map to the
506 name you want to change the relationship to. Keys that are monikers should map
507 to hashes mapping relationship names to their translation. You can do both at
508 once, and the more specific moniker version will be picked up first. So, for
509 instance, you could have
518 and relationships that would have been named C<bar> will now be named C<baz>
519 except that in the table whose moniker is C<Foo> it will be named C<blat>.
521 If it is a coderef, the argument passed will be a hashref of this form:
524 name => default relationship name,
525 type => the relationship type eg: C<has_many>,
526 local_class => name of the DBIC class we are building,
527 local_moniker => moniker of the DBIC class we are building,
528 local_columns => columns in this table in the relationship,
529 remote_class => name of the DBIC class we are related to,
530 remote_moniker => moniker of the DBIC class we are related to,
531 remote_columns => columns in the other table in the relationship,
534 DBICSL will try to use the value returned as the relationship name.
536 =head2 inflect_plural
538 Just like L</moniker_map> above (can be hash/code-ref, falls back to default
539 if hash key does not exist or coderef returns false), but acts as a map
540 for pluralizing relationship names. The default behavior is to utilize
541 L<Lingua::EN::Inflect::Phrase/to_PL>.
543 =head2 inflect_singular
545 As L</inflect_plural> above, but for singularizing relationship names.
546 Default behavior is to utilize L<Lingua::EN::Inflect::Phrase/to_S>.
548 =head2 schema_base_class
550 Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
552 =head2 schema_components
554 List of components to load into the Schema class.
556 =head2 result_base_class
558 Base class for your table classes (aka result classes). Defaults to
561 =head2 additional_base_classes
563 List of additional base classes all of your table classes will use.
565 =head2 left_base_classes
567 List of additional base classes all of your table classes will use
568 that need to be leftmost.
570 =head2 additional_classes
572 List of additional classes which all of your table classes will use.
576 List of additional components to be loaded into all of your Result
577 classes. A good example would be
578 L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime>
580 =head2 result_components_map
582 A hashref of moniker keys and component values. Unlike L</components>, which
583 loads the given components into every Result class, this option allows you to
584 load certain components for specified Result classes. For example:
586 result_components_map => {
587 StationVisited => '+YourApp::Schema::Component::StationVisited',
589 '+YourApp::Schema::Component::RouteChange',
590 'InflateColumn::DateTime',
594 You may use this in conjunction with L</components>.
598 List of L<Moose> roles to be applied to all of your Result classes.
600 =head2 result_roles_map
602 A hashref of moniker keys and role values. Unlike L</result_roles>, which
603 applies the given roles to every Result class, this option allows you to apply
604 certain roles for specified Result classes. For example:
606 result_roles_map => {
608 'YourApp::Role::Building',
609 'YourApp::Role::Destination',
611 RouteChange => 'YourApp::Role::TripEvent',
614 You may use this in conjunction with L</result_roles>.
616 =head2 use_namespaces
618 This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass
621 Generate result class names suitable for
622 L<DBIx::Class::Schema/load_namespaces> and call that instead of
623 L<DBIx::Class::Schema/load_classes>. When using this option you can also
624 specify any of the options for C<load_namespaces> (i.e. C<result_namespace>,
625 C<resultset_namespace>, C<default_resultset_class>), and they will be added
626 to the call (and the generated result class names adjusted appropriately).
628 =head2 dump_directory
630 The value of this option is a perl libdir pathname. Within
631 that directory this module will create a baseline manual
632 L<DBIx::Class::Schema> module set, based on what it creates at runtime.
634 The created schema class will have the same classname as the one on
635 which you are setting this option (and the ResultSource classes will be
636 based on this name as well).
638 Normally you wouldn't hard-code this setting in your schema class, as it
639 is meant for one-time manual usage.
641 See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the
642 recommended way to access this functionality.
644 =head2 dump_overwrite
646 Deprecated. See L</really_erase_my_files> below, which does *not* mean
647 the same thing as the old C<dump_overwrite> setting from previous releases.
649 =head2 really_erase_my_files
651 Default false. If true, Loader will unconditionally delete any existing
652 files before creating the new ones from scratch when dumping a schema to disk.
654 The default behavior is instead to only replace the top portion of the
655 file, up to and including the final stanza which contains
656 C<# DO NOT MODIFY THE FIRST PART OF THIS FILE>
657 leaving any customizations you placed after that as they were.
659 When C<really_erase_my_files> is not set, if the output file already exists,
660 but the aforementioned final stanza is not found, or the checksum
661 contained there does not match the generated contents, Loader will
662 croak and not touch the file.
664 You should really be using version control on your schema classes (and all
665 of the rest of your code for that matter). Don't blame me if a bug in this
666 code wipes something out when it shouldn't have, you've been warned.
668 =head2 overwrite_modifications
670 Default false. If false, when updating existing files, Loader will
671 refuse to modify any Loader-generated code that has been modified
672 since its last run (as determined by the checksum Loader put in its
675 If true, Loader will discard any manual modifications that have been
676 made to Loader-generated code.
678 Again, you should be using version control on your schema classes. Be
679 careful with this option.
681 =head2 custom_column_info
683 Hook for adding extra attributes to the
684 L<column_info|DBIx::Class::ResultSource/column_info> for a column.
686 Must be a coderef that returns a hashref with the extra attributes.
688 Receives the table name, column name and column_info.
692 custom_column_info => sub {
693 my ($table_name, $column_name, $column_info) = @_;
695 if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') {
696 return { is_snoopy => 1 };
700 This attribute can also be used to set C<inflate_datetime> on a non-datetime
701 column so it also receives the L</datetime_timezone> and/or L</datetime_locale>.
703 =head2 datetime_timezone
705 Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all
706 columns with the DATE/DATETIME/TIMESTAMP data_types.
708 =head2 datetime_locale
710 Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all
711 columns with the DATE/DATETIME/TIMESTAMP data_types.
713 =head2 datetime_undef_if_invalid
715 Pass a C<0> for this option when using MySQL if you B<DON'T> want C<<
716 datetime_undef_if_invalid => 1 >> in your column info for DATE, DATETIME and
719 The default is recommended to deal with data such as C<00/00/00> which
720 sometimes ends up in such columns in MySQL.
724 File in Perl format, which should return a HASH reference, from which to read
729 Normally database names are lowercased and split by underscore, use this option
730 if you have CamelCase database names.
732 Drivers for case sensitive databases like Sybase ASE or MSSQL with a
733 case-sensitive collation will turn this option on unconditionally.
735 B<NOTE:> L</naming> = C<v8> is highly recommended with this option as the
736 semantics of this mode are much improved for CamelCase database names.
738 L</naming> = C<v7> or greater is required with this option.
740 =head2 qualify_objects
742 Set to true to prepend the L</db_schema> to table names for C<<
743 __PACKAGE__->table >> calls, and to some other things like Oracle sequences.
747 Creates Schema and Result classes that use L<Moose>, L<MooseX::NonMoose> and
748 L<MooseX::MarkAsMethods> (or L<namespace::autoclean>, see below). The default
749 content after the md5 sum also makes the classes immutable.
751 It is safe to upgrade your existing Schema to this option.
753 =head2 only_autoclean
755 By default, we use L<MooseX::MarkAsMethods> to remove imported functions from
756 your generated classes. It uses L<namespace::autoclean> to do this, after
757 telling your object's metaclass that any operator L<overload>s in your class
758 are methods, which will cause namespace::autoclean to spare them from removal.
760 This prevents the "Hey, where'd my overloads go?!" effect.
762 If you don't care about operator overloads, enabling this option falls back to
763 just using L<namespace::autoclean> itself.
765 If none of the above made any sense, or you don't have some pressing need to
766 only use L<namespace::autoclean>, leaving this set to the default is
769 =head2 col_collision_map
771 This option controls how accessors for column names which collide with perl
772 methods are named. See L</COLUMN ACCESSOR COLLISIONS> for more information.
774 This option takes either a single L<sprintf|perlfunc/sprintf> format or a hashref of
775 strings which are compiled to regular expressions that map to
776 L<sprintf|perlfunc/sprintf> formats.
780 col_collision_map => 'column_%s'
782 col_collision_map => { '(.*)' => 'column_%s' }
784 col_collision_map => { '(foo).*(bar)' => 'column_%s_%s' }
786 =head2 rel_collision_map
788 Works just like L</col_collision_map>, but for relationship names/accessors
789 rather than column names/accessors.
791 The default is to just append C<_rel> to the relationship name, see
792 L</RELATIONSHIP NAME COLLISIONS>.
794 =head2 uniq_to_primary
796 Automatically promotes the largest unique constraints with non-nullable columns
797 on tables to primary keys, assuming there is only one largest unique
800 =head2 filter_generated_code
802 An optional hook that lets you filter the generated text for various classes
803 through a function that change it in any way that you want. The function will
804 receive the type of file, C<schema> or C<result>, class and code; and returns
805 the new code to use instead. For instance you could add custom comments, or do
806 anything else that you want.
808 The option can also be set to a string, which is then used as a filter program,
811 If this exists but fails to return text matching C</\bpackage\b/>, no file will
814 filter_generated_code => sub {

2799 Returns a hashref of loaded table to moniker mappings. There will
2800 be two entries for each table, the original name and the "normalized"
2801 name, in the case that the two are different (such as databases
2802 that like uppercase table names, or preserve your original mixed-case
2803 definitions, or what-have-you).
2807 Returns a hashref of table to class mappings. In some cases it will
2808 contain multiple entries per table for the original and normalized table
2809 names, as above in L</monikers>.
2811 =head1 NON-ENGLISH DATABASES
2813 If you use the loader on a database with table and column names in a language
2814 other than English, you will want to turn off the English language specific
2817 To do so, use something like this in your laoder options:
2819 naming => { monikers => 'v4' },
2820 inflect_singular => sub { "$_[0]_rel" },
2821 inflect_plural => sub { "$_[0]_rel" },
2823 =head1 COLUMN ACCESSOR COLLISIONS
2825 Occasionally you may have a column name that collides with a perl method, such
2826 as C<can>. In such cases, the default action is to set the C<accessor> of the
2827 column spec to C<undef>.
2829 You can then name the accessor yourself by placing code such as the following
2832 __PACKAGE__->add_column('+can' => { accessor => 'my_can' });
2834 Another option is to use the L</col_collision_map> option.
2836 =head1 RELATIONSHIP NAME COLLISIONS
2838 In very rare cases, you may get a collision between a generated relationship
2839 name and a method in your Result class, for example if you have a foreign key
2840 called C<belongs_to>.
2842 This is a problem because relationship names are also relationship accessor
2843 methods in L<DBIx::Class>.
2845 The default behavior is to append C<_rel> to the relationship name and print
2846 out a warning that refers to this text.
2848 You can also control the renaming with the L</rel_collision_map> option.
