89 DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.
93 See L<DBIx::Class::Schema::Loader>
97 This is the base class for the storage-specific C<DBIx::Class::Schema::*>
98 classes, and implements the common functionality between them.
100 =head1 CONSTRUCTOR OPTIONS
102 These constructor options are the base options for
103 L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are:
105 =head2 skip_relationships
107 Skip setting up relationships. The default is to attempt the loading
110 =head2 skip_load_external
112 Skip loading of other classes in @INC. The default is to merge all other classes
113 with the same name found in @INC into the schema file we are creating.
117 Static schemas (ones dumped to disk) will, by default, use the new-style
118 relationship names and singularized Results, unless you're overwriting an
119 existing dump made by an older version of L<DBIx::Class::Schema::Loader>, in
120 which case the backward compatible RelBuilder will be activated, and the
121 appropriate monikerization used.
127 will disable the backward-compatible RelBuilder and use
128 the new-style relationship names along with singularized Results, even when
129 overwriting a dump made with an earlier version.
131 The option also takes a hashref:
133 naming => { relationships => 'v7', monikers => 'v7' }
141 How to name relationship accessors.
145 How to name Result classes.
147 =item column_accessors
149 How to name column accessors in Result classes.
159 Latest style, whatever that happens to be.
163 Unsingularlized monikers, C<has_many> only relationships with no _id stripping.
167 Monikers singularized as whole words, C<might_have> relationships for FKs on
168 C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships.
170 Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for
175 All monikers and relationships are inflected using
176 L<Lingua::EN::Inflect::Phrase>, and there is more aggressive C<_id> stripping
177 from relationship names.
179 In general, there is very little difference between v5 and v6 schemas.
183 This mode is identical to C<v6> mode, except that monikerization of CamelCase
184 table names is also done correctly.
186 CamelCase column names in case-preserving mode will also be handled correctly
187 for relationship name inflection. See L</preserve_case>.
189 In this mode, CamelCase L</column_accessors> are normalized based on case
190 transition instead of just being lowercased, so C<FooId> becomes C<foo_id>.
192 If you don't have any CamelCase table or column names, you can upgrade without
193 breaking any of your code.
197 Dynamic schemas will always default to the 0.04XXX relationship names and won't
198 singularize Results for backward compatibility, to activate the new RelBuilder
199 and singularization put this in your C<Schema.pm> file:
201 __PACKAGE__->naming('current');
203 Or if you prefer to use 0.05XXX features but insure that nothing breaks in the
204 next major version upgrade:
206 __PACKAGE__->naming('v5');
210 By default POD will be generated for columns and relationships, using database
211 metadata for the text if available and supported.
213 Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only
214 supported for Postgres right now.
216 Set this to C<0> to turn off all POD generation.
218 =head2 pod_comment_mode
220 Controls where table comments appear in the generated POD. Smaller table
221 comments are appended to the C<NAME> section of the documentation, and larger
222 ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION>
223 section to be generated with the comment always, only use C<NAME>, or choose
224 the length threshold at which the comment is forced into the description.
230 Use C<NAME> section only.
234 Force C<DESCRIPTION> always.
238 Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the
243 =head2 pod_comment_spillover_length
245 When pod_comment_mode is set to C<auto>, this is the length of the comment at
246 which it will be forced into a separate description section.
250 =head2 relationship_attrs
252 Hashref of attributes to pass to each generated relationship, listed
253 by type. Also supports relationship type 'all', containing options to
254 pass to all generated relationships. Attributes set for more specific
255 relationship types override those set in 'all'.
259 relationship_attrs => {
260 belongs_to => { is_deferrable => 1 },
263 use this to make your foreign key constraints DEFERRABLE.
267 If set to true, each constructive L<DBIx::Class> statement the loader
268 decides to execute will be C<warn>-ed before execution.
272 Set the name of the schema to load (schema in the sense that your database
273 vendor means it). Does not currently support loading more than one schema
278 Only load tables matching regex. Best specified as a qr// regex.
282 Exclude tables matching regex. Best specified as a qr// regex.
286 Overrides the default table name to moniker translation. Can be either
287 a hashref of table keys and moniker values, or a coderef for a translator
288 function taking a single scalar table name argument and returning
289 a scalar moniker. If the hash entry does not exist, or the function
290 returns a false value, the code falls back to default behavior
293 The default behavior is to split on case transition and non-alphanumeric
294 boundaries, singularize the resulting phrase, then join the titlecased words
297 Table Name | Moniker Name
298 ---------------------------------
300 luser_group | LuserGroup
301 luser-opts | LuserOpt
302 stations_visited | StationVisited
303 routeChange | RouteChange
305 =head2 inflect_plural
307 Just like L</moniker_map> above (can be hash/code-ref, falls back to default
308 if hash key does not exist or coderef returns false), but acts as a map
309 for pluralizing relationship names. The default behavior is to utilize
310 L<Lingua::EN::Inflect::Number/to_PL>.
312 =head2 inflect_singular
314 As L</inflect_plural> above, but for singularizing relationship names.
315 Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>.
317 =head2 schema_base_class
319 Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
321 =head2 result_base_class
323 Base class for your table classes (aka result classes). Defaults to
326 =head2 additional_base_classes
328 List of additional base classes all of your table classes will use.
330 =head2 left_base_classes
332 List of additional base classes all of your table classes will use
333 that need to be leftmost.
335 =head2 additional_classes
337 List of additional classes which all of your table classes will use.
341 List of additional components to be loaded into all of your table
342 classes. A good example would be
343 L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime>
345 =head2 resultset_components
347 List of additional ResultSet components to be loaded into your table
348 classes. A good example would be C<AlwaysRS>. Component
349 C<ResultSetManager> will be automatically added to the above
350 C<components> list if this option is set.
352 =head2 use_namespaces
354 This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass
357 Generate result class names suitable for
358 L<DBIx::Class::Schema/load_namespaces> and call that instead of
359 L<DBIx::Class::Schema/load_classes>. When using this option you can also
360 specify any of the options for C<load_namespaces> (i.e. C<result_namespace>,
361 C<resultset_namespace>, C<default_resultset_class>), and they will be added
362 to the call (and the generated result class names adjusted appropriately).
364 =head2 dump_directory
366 This option is designed to be a tool to help you transition from this
367 loader to a manually-defined schema when you decide it's time to do so.
369 The value of this option is a perl libdir pathname. Within
370 that directory this module will create a baseline manual
371 L<DBIx::Class::Schema> module set, based on what it creates at runtime
374 The created schema class will have the same classname as the one on
375 which you are setting this option (and the ResultSource classes will be
376 based on this name as well).
378 Normally you wouldn't hard-code this setting in your schema class, as it
379 is meant for one-time manual usage.
381 See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the
382 recommended way to access this functionality.
384 =head2 dump_overwrite
386 Deprecated. See L</really_erase_my_files> below, which does *not* mean
387 the same thing as the old C<dump_overwrite> setting from previous releases.
389 =head2 really_erase_my_files
391 Default false. If true, Loader will unconditionally delete any existing
392 files before creating the new ones from scratch when dumping a schema to disk.
394 The default behavior is instead to only replace the top portion of the
395 file, up to and including the final stanza which contains
396 C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!>
397 leaving any customizations you placed after that as they were.
399 When C<really_erase_my_files> is not set, if the output file already exists,
400 but the aforementioned final stanza is not found, or the checksum
401 contained there does not match the generated contents, Loader will
402 croak and not touch the file.
404 You should really be using version control on your schema classes (and all
405 of the rest of your code for that matter). Don't blame me if a bug in this
406 code wipes something out when it shouldn't have, you've been warned.
408 =head2 overwrite_modifications
410 Default false. If false, when updating existing files, Loader will
411 refuse to modify any Loader-generated code that has been modified
412 since its last run (as determined by the checksum Loader put in its
415 If true, Loader will discard any manual modifications that have been
416 made to Loader-generated code.
418 Again, you should be using version control on your schema classes. Be
419 careful with this option.
421 =head2 custom_column_info
423 Hook for adding extra attributes to the
424 L<column_info|DBIx::Class::ResultSource/column_info> for a column.
426 Must be a coderef that returns a hashref with the extra attributes.
428 Receives the table name, column name and column_info.
432 custom_column_info => sub {
433 my ($table_name, $column_name, $column_info) = @_;
435 if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') {
436 return { is_snoopy => 1 };
440 This attribute can also be used to set C<inflate_datetime> on a non-datetime
441 column so it also receives the L</datetime_timezone> and/or L</datetime_locale>.
443 =head2 datetime_timezone
445 Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all
446 columns with the DATE/DATETIME/TIMESTAMP data_types.
448 =head2 datetime_locale
450 Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all
451 columns with the DATE/DATETIME/TIMESTAMP data_types.
455 File in Perl format, which should return a HASH reference, from which to read
460 Usually column names are lowercased, to make them easier to work with in
461 L<DBIx::Class>. This option lets you turn this behavior off, if the driver
464 Drivers for case sensitive databases like Sybase ASE or MSSQL with a
465 case-sensitive collation will turn this option on unconditionally.
467 Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support
470 =head1 qualify_objects
472 Set to true to prepend the L</db_schema> to table names for C<<
473 __PACKAGE__->table >> calls, and to some other things like Oracle sequences.
477 None of these methods are intended for direct invocation by regular
478 users of L<DBIx::Class::Schema::Loader>. Some are proxied via
479 L<DBIx::Class::Schema::Loader>.

1874 name, in the case that the two are different (such as databases
