91 DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.
95 See L<DBIx::Class::Schema::Loader>
99 This is the base class for the storage-specific C<DBIx::Class::Schema::*>
100 classes, and implements the common functionality between them.
102 =head1 CONSTRUCTOR OPTIONS
104 These constructor options are the base options for
105 L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are:
107 =head2 skip_relationships
109 Skip setting up relationships. The default is to attempt the loading
112 =head2 skip_load_external
114 Skip loading of other classes in @INC. The default is to merge all other classes
115 with the same name found in @INC into the schema file we are creating.
119 Static schemas (ones dumped to disk) will, by default, use the new-style
120 relationship names and singularized Results, unless you're overwriting an
121 existing dump made by an older version of L<DBIx::Class::Schema::Loader>, in
122 which case the backward compatible RelBuilder will be activated, and the
123 appropriate monikerization used.
129 will disable the backward-compatible RelBuilder and use
130 the new-style relationship names along with singularized Results, even when
131 overwriting a dump made with an earlier version.
133 The option also takes a hashref:
135 naming => { relationships => 'v7', monikers => 'v7' }
143 How to name relationship accessors.
147 How to name Result classes.
149 =item column_accessors
151 How to name column accessors in Result classes.
161 Latest style, whatever that happens to be.
165 Unsingularlized monikers, C<has_many> only relationships with no _id stripping.
169 Monikers singularized as whole words, C<might_have> relationships for FKs on
170 C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships.
172 Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for
177 All monikers and relationships are inflected using
178 L<Lingua::EN::Inflect::Phrase>, and there is more aggressive C<_id> stripping
179 from relationship names.
181 In general, there is very little difference between v5 and v6 schemas.
185 This mode is identical to C<v6> mode, except that monikerization of CamelCase
186 table names is also done correctly.
188 CamelCase column names in case-preserving mode will also be handled correctly
189 for relationship name inflection. See L</preserve_case>.
191 In this mode, CamelCase L</column_accessors> are normalized based on case
192 transition instead of just being lowercased, so C<FooId> becomes C<foo_id>.
194 If you don't have any CamelCase table or column names, you can upgrade without
195 breaking any of your code.
199 Dynamic schemas will always default to the 0.04XXX relationship names and won't
200 singularize Results for backward compatibility, to activate the new RelBuilder
201 and singularization put this in your C<Schema.pm> file:
203 __PACKAGE__->naming('current');
205 Or if you prefer to use 0.07XXX features but insure that nothing breaks in the
206 next major version upgrade:
208 __PACKAGE__->naming('v7');
212 By default POD will be generated for columns and relationships, using database
213 metadata for the text if available and supported.
215 Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only
216 supported for Postgres right now.
218 Set this to C<0> to turn off all POD generation.
220 =head2 pod_comment_mode
222 Controls where table comments appear in the generated POD. Smaller table
223 comments are appended to the C<NAME> section of the documentation, and larger
224 ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION>
225 section to be generated with the comment always, only use C<NAME>, or choose
226 the length threshold at which the comment is forced into the description.
232 Use C<NAME> section only.
236 Force C<DESCRIPTION> always.
240 Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the
245 =head2 pod_comment_spillover_length
247 When pod_comment_mode is set to C<auto>, this is the length of the comment at
248 which it will be forced into a separate description section.
252 =head2 relationship_attrs
254 Hashref of attributes to pass to each generated relationship, listed
255 by type. Also supports relationship type 'all', containing options to
256 pass to all generated relationships. Attributes set for more specific
257 relationship types override those set in 'all'.
261 relationship_attrs => {
262 belongs_to => { is_deferrable => 0 },
265 use this to turn off DEFERRABLE on your foreign key constraints.
269 If set to true, each constructive L<DBIx::Class> statement the loader
270 decides to execute will be C<warn>-ed before execution.
274 Set the name of the schema to load (schema in the sense that your database
275 vendor means it). Does not currently support loading more than one schema
280 Only load tables matching regex. Best specified as a qr// regex.
284 Exclude tables matching regex. Best specified as a qr// regex.
288 Overrides the default table name to moniker translation. Can be either
289 a hashref of table keys and moniker values, or a coderef for a translator
290 function taking a single scalar table name argument and returning
291 a scalar moniker. If the hash entry does not exist, or the function
292 returns a false value, the code falls back to default behavior
295 The default behavior is to split on case transition and non-alphanumeric
296 boundaries, singularize the resulting phrase, then join the titlecased words
299 Table Name | Moniker Name
300 ---------------------------------
302 luser_group | LuserGroup
303 luser-opts | LuserOpt
304 stations_visited | StationVisited
305 routeChange | RouteChange
307 =head2 inflect_plural
309 Just like L</moniker_map> above (can be hash/code-ref, falls back to default
310 if hash key does not exist or coderef returns false), but acts as a map
311 for pluralizing relationship names. The default behavior is to utilize
312 L<Lingua::EN::Inflect::Number/to_PL>.
314 =head2 inflect_singular
316 As L</inflect_plural> above, but for singularizing relationship names.
317 Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>.
319 =head2 schema_base_class
321 Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
323 =head2 result_base_class
325 Base class for your table classes (aka result classes). Defaults to
328 =head2 additional_base_classes
330 List of additional base classes all of your table classes will use.
332 =head2 left_base_classes
334 List of additional base classes all of your table classes will use
335 that need to be leftmost.
337 =head2 additional_classes
339 List of additional classes which all of your table classes will use.
343 List of additional components to be loaded into all of your table
344 classes. A good example would be
345 L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime>
347 =head2 resultset_components
349 List of additional ResultSet components to be loaded into your table
350 classes. A good example would be C<AlwaysRS>. Component
351 C<ResultSetManager> will be automatically added to the above
352 C<components> list if this option is set.
354 =head2 use_namespaces
356 This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass
359 Generate result class names suitable for
360 L<DBIx::Class::Schema/load_namespaces> and call that instead of
361 L<DBIx::Class::Schema/load_classes>. When using this option you can also
362 specify any of the options for C<load_namespaces> (i.e. C<result_namespace>,
363 C<resultset_namespace>, C<default_resultset_class>), and they will be added
364 to the call (and the generated result class names adjusted appropriately).
366 =head2 dump_directory
368 This option is designed to be a tool to help you transition from this
369 loader to a manually-defined schema when you decide it's time to do so.
371 The value of this option is a perl libdir pathname. Within
372 that directory this module will create a baseline manual
373 L<DBIx::Class::Schema> module set, based on what it creates at runtime
376 The created schema class will have the same classname as the one on
377 which you are setting this option (and the ResultSource classes will be
378 based on this name as well).
380 Normally you wouldn't hard-code this setting in your schema class, as it
381 is meant for one-time manual usage.
383 See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the
384 recommended way to access this functionality.
386 =head2 dump_overwrite
388 Deprecated. See L</really_erase_my_files> below, which does *not* mean
389 the same thing as the old C<dump_overwrite> setting from previous releases.
391 =head2 really_erase_my_files
393 Default false. If true, Loader will unconditionally delete any existing
394 files before creating the new ones from scratch when dumping a schema to disk.
396 The default behavior is instead to only replace the top portion of the
397 file, up to and including the final stanza which contains
398 C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!>
399 leaving any customizations you placed after that as they were.
401 When C<really_erase_my_files> is not set, if the output file already exists,
402 but the aforementioned final stanza is not found, or the checksum
403 contained there does not match the generated contents, Loader will
404 croak and not touch the file.
406 You should really be using version control on your schema classes (and all
407 of the rest of your code for that matter). Don't blame me if a bug in this
408 code wipes something out when it shouldn't have, you've been warned.
410 =head2 overwrite_modifications
412 Default false. If false, when updating existing files, Loader will
413 refuse to modify any Loader-generated code that has been modified
414 since its last run (as determined by the checksum Loader put in its
417 If true, Loader will discard any manual modifications that have been
418 made to Loader-generated code.
420 Again, you should be using version control on your schema classes. Be
421 careful with this option.
423 =head2 custom_column_info
425 Hook for adding extra attributes to the
426 L<column_info|DBIx::Class::ResultSource/column_info> for a column.
428 Must be a coderef that returns a hashref with the extra attributes.
430 Receives the table name, column name and column_info.
434 custom_column_info => sub {
435 my ($table_name, $column_name, $column_info) = @_;
437 if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') {
438 return { is_snoopy => 1 };
442 This attribute can also be used to set C<inflate_datetime> on a non-datetime
443 column so it also receives the L</datetime_timezone> and/or L</datetime_locale>.
445 =head2 datetime_timezone
447 Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all
448 columns with the DATE/DATETIME/TIMESTAMP data_types.
450 =head2 datetime_locale
452 Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all
453 columns with the DATE/DATETIME/TIMESTAMP data_types.
457 File in Perl format, which should return a HASH reference, from which to read
462 Usually column names are lowercased, to make them easier to work with in
463 L<DBIx::Class>. This option lets you turn this behavior off, if the driver
466 Drivers for case sensitive databases like Sybase ASE or MSSQL with a
467 case-sensitive collation will turn this option on unconditionally.
469 Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support
472 =head2 qualify_objects
474 Set to true to prepend the L</db_schema> to table names for C<<
475 __PACKAGE__->table >> calls, and to some other things like Oracle sequences.
479 Creates Schema and Result classes that use L<Moose>, L<MooseX::NonMoose> and
480 L<namespace::autoclean>. The default content after the md5 sum also makes the
483 It is safe to upgrade your existing Schema to this option.
487 None of these methods are intended for direct invocation by regular
488 users of L<DBIx::Class::Schema::Loader>. Some are proxied via
489 L<DBIx::Class::Schema::Loader>.
