92 DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.
96 See L<DBIx::Class::Schema::Loader>
100 This is the base class for the storage-specific C<DBIx::Class::Schema::*>
101 classes, and implements the common functionality between them.
103 =head1 CONSTRUCTOR OPTIONS
105 These constructor options are the base options for
106 L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are:
108 =head2 skip_relationships
110 Skip setting up relationships. The default is to attempt the loading
113 =head2 skip_load_external
115 Skip loading of other classes in @INC. The default is to merge all other classes
116 with the same name found in @INC into the schema file we are creating.
120 Static schemas (ones dumped to disk) will, by default, use the new-style
121 relationship names and singularized Results, unless you're overwriting an
122 existing dump made by an older version of L<DBIx::Class::Schema::Loader>, in
123 which case the backward compatible RelBuilder will be activated, and the
124 appropriate monikerization used.
130 will disable the backward-compatible RelBuilder and use
131 the new-style relationship names along with singularized Results, even when
132 overwriting a dump made with an earlier version.
134 The option also takes a hashref:
136 naming => { relationships => 'v7', monikers => 'v7' }
144 How to name relationship accessors.
148 How to name Result classes.
150 =item column_accessors
152 How to name column accessors in Result classes.
162 Latest style, whatever that happens to be.
166 Unsingularlized monikers, C<has_many> only relationships with no _id stripping.
170 Monikers singularized as whole words, C<might_have> relationships for FKs on
171 C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships.
173 Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for
178 All monikers and relationships are inflected using
179 L<Lingua::EN::Inflect::Phrase>, and there is more aggressive C<_id> stripping
180 from relationship names.
182 In general, there is very little difference between v5 and v6 schemas.
186 This mode is identical to C<v6> mode, except that monikerization of CamelCase
187 table names is also done correctly.
189 CamelCase column names in case-preserving mode will also be handled correctly
190 for relationship name inflection. See L</preserve_case>.
192 In this mode, CamelCase L</column_accessors> are normalized based on case
193 transition instead of just being lowercased, so C<FooId> becomes C<foo_id>.
195 If you don't have any CamelCase table or column names, you can upgrade without
196 breaking any of your code.
200 Dynamic schemas will always default to the 0.04XXX relationship names and won't
201 singularize Results for backward compatibility, to activate the new RelBuilder
202 and singularization put this in your C<Schema.pm> file:
204 __PACKAGE__->naming('current');
206 Or if you prefer to use 0.07XXX features but insure that nothing breaks in the
207 next major version upgrade:
209 __PACKAGE__->naming('v7');
213 By default POD will be generated for columns and relationships, using database
214 metadata for the text if available and supported.
216 Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only
217 supported for Postgres right now.
219 Set this to C<0> to turn off all POD generation.
221 =head2 pod_comment_mode
223 Controls where table comments appear in the generated POD. Smaller table
224 comments are appended to the C<NAME> section of the documentation, and larger
225 ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION>
226 section to be generated with the comment always, only use C<NAME>, or choose
227 the length threshold at which the comment is forced into the description.
233 Use C<NAME> section only.
237 Force C<DESCRIPTION> always.
241 Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the
246 =head2 pod_comment_spillover_length
248 When pod_comment_mode is set to C<auto>, this is the length of the comment at
249 which it will be forced into a separate description section.
253 =head2 relationship_attrs
255 Hashref of attributes to pass to each generated relationship, listed
256 by type. Also supports relationship type 'all', containing options to
257 pass to all generated relationships. Attributes set for more specific
258 relationship types override those set in 'all'.
262 relationship_attrs => {
263 belongs_to => { is_deferrable => 0 },
266 use this to turn off DEFERRABLE on your foreign key constraints.
270 If set to true, each constructive L<DBIx::Class> statement the loader
271 decides to execute will be C<warn>-ed before execution.
275 Set the name of the schema to load (schema in the sense that your database
276 vendor means it). Does not currently support loading more than one schema
281 Only load tables matching regex. Best specified as a qr// regex.
285 Exclude tables matching regex. Best specified as a qr// regex.
289 Overrides the default table name to moniker translation. Can be either
290 a hashref of table keys and moniker values, or a coderef for a translator
291 function taking a single scalar table name argument and returning
292 a scalar moniker. If the hash entry does not exist, or the function
293 returns a false value, the code falls back to default behavior
296 The default behavior is to split on case transition and non-alphanumeric
297 boundaries, singularize the resulting phrase, then join the titlecased words
300 Table Name | Moniker Name
301 ---------------------------------
303 luser_group | LuserGroup
304 luser-opts | LuserOpt
305 stations_visited | StationVisited
306 routeChange | RouteChange
308 =head2 inflect_plural
310 Just like L</moniker_map> above (can be hash/code-ref, falls back to default
311 if hash key does not exist or coderef returns false), but acts as a map
312 for pluralizing relationship names. The default behavior is to utilize
313 L<Lingua::EN::Inflect::Phrase/to_PL>.
315 =head2 inflect_singular
317 As L</inflect_plural> above, but for singularizing relationship names.
318 Default behavior is to utilize L<Lingua::EN::Inflect::Phrase/to_S>.
320 =head2 schema_base_class
322 Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
324 =head2 result_base_class
326 Base class for your table classes (aka result classes). Defaults to
329 =head2 additional_base_classes
331 List of additional base classes all of your table classes will use.
333 =head2 left_base_classes
335 List of additional base classes all of your table classes will use
336 that need to be leftmost.
338 =head2 additional_classes
340 List of additional classes which all of your table classes will use.
344 List of additional components to be loaded into all of your table
345 classes. A good example would be
346 L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime>
348 =head2 resultset_components
350 List of additional ResultSet components to be loaded into your table
351 classes. A good example would be C<AlwaysRS>. Component
352 C<ResultSetManager> will be automatically added to the above
353 C<components> list if this option is set.
355 =head2 use_namespaces
357 This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass
360 Generate result class names suitable for
361 L<DBIx::Class::Schema/load_namespaces> and call that instead of
362 L<DBIx::Class::Schema/load_classes>. When using this option you can also
363 specify any of the options for C<load_namespaces> (i.e. C<result_namespace>,
364 C<resultset_namespace>, C<default_resultset_class>), and they will be added
365 to the call (and the generated result class names adjusted appropriately).
367 =head2 dump_directory
369 This option is designed to be a tool to help you transition from this
370 loader to a manually-defined schema when you decide it's time to do so.
372 The value of this option is a perl libdir pathname. Within
373 that directory this module will create a baseline manual
374 L<DBIx::Class::Schema> module set, based on what it creates at runtime
377 The created schema class will have the same classname as the one on
378 which you are setting this option (and the ResultSource classes will be
379 based on this name as well).
381 Normally you wouldn't hard-code this setting in your schema class, as it
382 is meant for one-time manual usage.
384 See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the
385 recommended way to access this functionality.
387 =head2 dump_overwrite
389 Deprecated. See L</really_erase_my_files> below, which does *not* mean
390 the same thing as the old C<dump_overwrite> setting from previous releases.
392 =head2 really_erase_my_files
394 Default false. If true, Loader will unconditionally delete any existing
395 files before creating the new ones from scratch when dumping a schema to disk.
397 The default behavior is instead to only replace the top portion of the
398 file, up to and including the final stanza which contains
399 C<# DO NOT MODIFY THE FIRST PART OF THIS FILE>
400 leaving any customizations you placed after that as they were.
402 When C<really_erase_my_files> is not set, if the output file already exists,
403 but the aforementioned final stanza is not found, or the checksum
404 contained there does not match the generated contents, Loader will
405 croak and not touch the file.
407 You should really be using version control on your schema classes (and all
408 of the rest of your code for that matter). Don't blame me if a bug in this
409 code wipes something out when it shouldn't have, you've been warned.
411 =head2 overwrite_modifications
413 Default false. If false, when updating existing files, Loader will
414 refuse to modify any Loader-generated code that has been modified
415 since its last run (as determined by the checksum Loader put in its
418 If true, Loader will discard any manual modifications that have been
419 made to Loader-generated code.
421 Again, you should be using version control on your schema classes. Be
422 careful with this option.
424 =head2 custom_column_info
426 Hook for adding extra attributes to the
427 L<column_info|DBIx::Class::ResultSource/column_info> for a column.
429 Must be a coderef that returns a hashref with the extra attributes.
431 Receives the table name, column name and column_info.
435 custom_column_info => sub {
436 my ($table_name, $column_name, $column_info) = @_;
438 if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') {
439 return { is_snoopy => 1 };
443 This attribute can also be used to set C<inflate_datetime> on a non-datetime
444 column so it also receives the L</datetime_timezone> and/or L</datetime_locale>.
446 =head2 datetime_timezone
448 Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all
449 columns with the DATE/DATETIME/TIMESTAMP data_types.
451 =head2 datetime_locale
453 Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all
454 columns with the DATE/DATETIME/TIMESTAMP data_types.
458 File in Perl format, which should return a HASH reference, from which to read
463 Usually column names are lowercased, to make them easier to work with in
464 L<DBIx::Class>. This option lets you turn this behavior off, if the driver
467 Drivers for case sensitive databases like Sybase ASE or MSSQL with a
468 case-sensitive collation will turn this option on unconditionally.
470 Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support
473 =head2 qualify_objects
475 Set to true to prepend the L</db_schema> to table names for C<<
476 __PACKAGE__->table >> calls, and to some other things like Oracle sequences.
480 Creates Schema and Result classes that use L<Moose>, L<MooseX::NonMoose> and
481 L<namespace::autoclean>. The default content after the md5 sum also makes the
484 It is safe to upgrade your existing Schema to this option.
486 =head2 col_collision_map
488 This option controls how accessors for column names which collide with perl
489 methods are named. See L</COLUMN ACCESSOR COLLISIONS> for more information.
491 This option takes either a single L<sprintf|perlfunc/sprintf> format or a hashref of
492 strings which are compiled to regular expressions that map to
493 L<sprintf|perlfunc/sprintf> formats.
497 col_collision_map => 'column_%s'
499 col_collision_map => { '(.*)' => 'column_%s' }
501 col_collision_map => { '(foo).*(bar)' => 'column_%s_%s' }
505 None of these methods are intended for direct invocation by regular
506 users of L<DBIx::Class::Schema::Loader>. Some are proxied via
507 L<DBIx::Class::Schema::Loader>.

2000 =head1 COLUMN ACCESSOR COLLISIONS
2002 Occasionally you may have a column name that collides with a perl method, such
2003 as C<can>. In such cases, the default action is to set the C<accessor> of the
2004 column spec to C<undef>.
2006 You can then name the accessor yourself by placing code such as the following
2009 __PACKAGE__->add_column('+can' => { accessor => 'my_can' });
2011 Another option is to use the L</col_collision_map> option.
