90 DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.
94 See L<DBIx::Class::Schema::Loader>
98 This is the base class for the storage-specific C<DBIx::Class::Schema::*>
99 classes, and implements the common functionality between them.
101 =head1 CONSTRUCTOR OPTIONS
103 These constructor options are the base options for
104 L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are:
106 =head2 skip_relationships
108 Skip setting up relationships. The default is to attempt the loading
111 =head2 skip_load_external
113 Skip loading of other classes in @INC. The default is to merge all other classes
114 with the same name found in @INC into the schema file we are creating.
118 Static schemas (ones dumped to disk) will, by default, use the new-style
119 relationship names and singularized Results, unless you're overwriting an
120 existing dump made by an older version of L<DBIx::Class::Schema::Loader>, in
121 which case the backward compatible RelBuilder will be activated, and the
122 appropriate monikerization used.
128 will disable the backward-compatible RelBuilder and use
129 the new-style relationship names along with singularized Results, even when
130 overwriting a dump made with an earlier version.
132 The option also takes a hashref:
134 naming => { relationships => 'v7', monikers => 'v7' }
142 How to name relationship accessors.
146 How to name Result classes.
148 =item column_accessors
150 How to name column accessors in Result classes.
160 Latest style, whatever that happens to be.
164 Unsingularlized monikers, C<has_many> only relationships with no _id stripping.
168 Monikers singularized as whole words, C<might_have> relationships for FKs on
169 C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships.
171 Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for
176 All monikers and relationships are inflected using
177 L<Lingua::EN::Inflect::Phrase>, and there is more aggressive C<_id> stripping
178 from relationship names.
180 In general, there is very little difference between v5 and v6 schemas.
184 This mode is identical to C<v6> mode, except that monikerization of CamelCase
185 table names is also done correctly.
187 CamelCase column names in case-preserving mode will also be handled correctly
188 for relationship name inflection. See L</preserve_case>.
190 In this mode, CamelCase L</column_accessors> are normalized based on case
191 transition instead of just being lowercased, so C<FooId> becomes C<foo_id>.
193 If you don't have any CamelCase table or column names, you can upgrade without
194 breaking any of your code.
198 Dynamic schemas will always default to the 0.04XXX relationship names and won't
199 singularize Results for backward compatibility, to activate the new RelBuilder
200 and singularization put this in your C<Schema.pm> file:
202 __PACKAGE__->naming('current');
204 Or if you prefer to use 0.07XXX features but insure that nothing breaks in the
205 next major version upgrade:
207 __PACKAGE__->naming('v7');
211 By default POD will be generated for columns and relationships, using database
212 metadata for the text if available and supported.
214 Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only
215 supported for Postgres right now.
217 Set this to C<0> to turn off all POD generation.
219 =head2 pod_comment_mode
221 Controls where table comments appear in the generated POD. Smaller table
222 comments are appended to the C<NAME> section of the documentation, and larger
223 ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION>
224 section to be generated with the comment always, only use C<NAME>, or choose
225 the length threshold at which the comment is forced into the description.
231 Use C<NAME> section only.
235 Force C<DESCRIPTION> always.
239 Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the
244 =head2 pod_comment_spillover_length
246 When pod_comment_mode is set to C<auto>, this is the length of the comment at
247 which it will be forced into a separate description section.
251 =head2 relationship_attrs
253 Hashref of attributes to pass to each generated relationship, listed
254 by type. Also supports relationship type 'all', containing options to
255 pass to all generated relationships. Attributes set for more specific
256 relationship types override those set in 'all'.
260 relationship_attrs => {
261 belongs_to => { is_deferrable => 1 },
264 use this to make your foreign key constraints DEFERRABLE.
268 If set to true, each constructive L<DBIx::Class> statement the loader
269 decides to execute will be C<warn>-ed before execution.
273 Set the name of the schema to load (schema in the sense that your database
274 vendor means it). Does not currently support loading more than one schema
279 Only load tables matching regex. Best specified as a qr// regex.
283 Exclude tables matching regex. Best specified as a qr// regex.
287 Overrides the default table name to moniker translation. Can be either
288 a hashref of table keys and moniker values, or a coderef for a translator
289 function taking a single scalar table name argument and returning
290 a scalar moniker. If the hash entry does not exist, or the function
291 returns a false value, the code falls back to default behavior
294 The default behavior is to split on case transition and non-alphanumeric
295 boundaries, singularize the resulting phrase, then join the titlecased words
298 Table Name | Moniker Name
299 ---------------------------------
301 luser_group | LuserGroup
302 luser-opts | LuserOpt
303 stations_visited | StationVisited
304 routeChange | RouteChange
306 =head2 inflect_plural
308 Just like L</moniker_map> above (can be hash/code-ref, falls back to default
309 if hash key does not exist or coderef returns false), but acts as a map
310 for pluralizing relationship names. The default behavior is to utilize
311 L<Lingua::EN::Inflect::Number/to_PL>.
313 =head2 inflect_singular
315 As L</inflect_plural> above, but for singularizing relationship names.
316 Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>.
318 =head2 schema_base_class
320 Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
322 =head2 result_base_class
324 Base class for your table classes (aka result classes). Defaults to
327 =head2 additional_base_classes
329 List of additional base classes all of your table classes will use.
331 =head2 left_base_classes
333 List of additional base classes all of your table classes will use
334 that need to be leftmost.
336 =head2 additional_classes
338 List of additional classes which all of your table classes will use.
342 List of additional components to be loaded into all of your table
343 classes. A good example would be
344 L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime>
346 =head2 resultset_components
348 List of additional ResultSet components to be loaded into your table
349 classes. A good example would be C<AlwaysRS>. Component
350 C<ResultSetManager> will be automatically added to the above
351 C<components> list if this option is set.
353 =head2 use_namespaces
355 This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass
358 Generate result class names suitable for
359 L<DBIx::Class::Schema/load_namespaces> and call that instead of
360 L<DBIx::Class::Schema/load_classes>. When using this option you can also
361 specify any of the options for C<load_namespaces> (i.e. C<result_namespace>,
362 C<resultset_namespace>, C<default_resultset_class>), and they will be added
363 to the call (and the generated result class names adjusted appropriately).
365 =head2 dump_directory
367 This option is designed to be a tool to help you transition from this
368 loader to a manually-defined schema when you decide it's time to do so.
370 The value of this option is a perl libdir pathname. Within
371 that directory this module will create a baseline manual
372 L<DBIx::Class::Schema> module set, based on what it creates at runtime
375 The created schema class will have the same classname as the one on
376 which you are setting this option (and the ResultSource classes will be
377 based on this name as well).
379 Normally you wouldn't hard-code this setting in your schema class, as it
380 is meant for one-time manual usage.
382 See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the
383 recommended way to access this functionality.
385 =head2 dump_overwrite
387 Deprecated. See L</really_erase_my_files> below, which does *not* mean
388 the same thing as the old C<dump_overwrite> setting from previous releases.
390 =head2 really_erase_my_files
392 Default false. If true, Loader will unconditionally delete any existing
393 files before creating the new ones from scratch when dumping a schema to disk.
395 The default behavior is instead to only replace the top portion of the
396 file, up to and including the final stanza which contains
397 C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!>
398 leaving any customizations you placed after that as they were.
400 When C<really_erase_my_files> is not set, if the output file already exists,
401 but the aforementioned final stanza is not found, or the checksum
402 contained there does not match the generated contents, Loader will
403 croak and not touch the file.
405 You should really be using version control on your schema classes (and all
406 of the rest of your code for that matter). Don't blame me if a bug in this
407 code wipes something out when it shouldn't have, you've been warned.
409 =head2 overwrite_modifications
411 Default false. If false, when updating existing files, Loader will
412 refuse to modify any Loader-generated code that has been modified
413 since its last run (as determined by the checksum Loader put in its
416 If true, Loader will discard any manual modifications that have been
417 made to Loader-generated code.
419 Again, you should be using version control on your schema classes. Be
420 careful with this option.
422 =head2 custom_column_info
424 Hook for adding extra attributes to the
425 L<column_info|DBIx::Class::ResultSource/column_info> for a column.
427 Must be a coderef that returns a hashref with the extra attributes.
429 Receives the table name, column name and column_info.
433 custom_column_info => sub {
434 my ($table_name, $column_name, $column_info) = @_;
436 if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') {
437 return { is_snoopy => 1 };
441 This attribute can also be used to set C<inflate_datetime> on a non-datetime
442 column so it also receives the L</datetime_timezone> and/or L</datetime_locale>.
444 =head2 datetime_timezone
446 Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all
447 columns with the DATE/DATETIME/TIMESTAMP data_types.
449 =head2 datetime_locale
451 Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all
452 columns with the DATE/DATETIME/TIMESTAMP data_types.
456 File in Perl format, which should return a HASH reference, from which to read
461 Usually column names are lowercased, to make them easier to work with in
462 L<DBIx::Class>. This option lets you turn this behavior off, if the driver
465 Drivers for case sensitive databases like Sybase ASE or MSSQL with a
466 case-sensitive collation will turn this option on unconditionally.
468 Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support
471 =head2 qualify_objects
473 Set to true to prepend the L</db_schema> to table names for C<<
474 __PACKAGE__->table >> calls, and to some other things like Oracle sequences.
478 Creates Schema and Result classes that use L<Moose>, L<MooseX::NonMoose> and
479 L<namespace::autoclean>. The default custom content also makes the classes
482 It is safe to upgrade your existing Schema to this option.
486 None of these methods are intended for direct invocation by regular
487 users of L<DBIx::Class::Schema::Loader>. Some are proxied via
488 L<DBIx::Class::Schema::Loader>.

1946 name, in the case that the two are different (such as databases

1954 names, as above in L</monikers>.
