87 DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.
91 See L<DBIx::Class::Schema::Loader>
95 This is the base class for the storage-specific C<DBIx::Class::Schema::*>
96 classes, and implements the common functionality between them.
98 =head1 CONSTRUCTOR OPTIONS
100 These constructor options are the base options for
101 L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are:
103 =head2 skip_relationships
105 Skip setting up relationships. The default is to attempt the loading
108 =head2 skip_load_external
110 Skip loading of other classes in @INC. The default is to merge all other classes
111 with the same name found in @INC into the schema file we are creating.
115 Static schemas (ones dumped to disk) will, by default, use the new-style
116 relationship names and singularized Results, unless you're overwriting an
117 existing dump made by an older version of L<DBIx::Class::Schema::Loader>, in
118 which case the backward compatible RelBuilder will be activated, and the
119 appropriate monikerization used.
125 will disable the backward-compatible RelBuilder and use
126 the new-style relationship names along with singularized Results, even when
127 overwriting a dump made with an earlier version.
129 The option also takes a hashref:
131 naming => { relationships => 'v6', monikers => 'v6' }
139 How to name relationship accessors.
143 How to name Result classes.
145 =item column_accessors
147 How to name column accessors in Result classes.
157 Latest style, whatever that happens to be.
161 Unsingularlized monikers, C<has_many> only relationships with no _id stripping.
165 Monikers singularized as whole words, C<might_have> relationships for FKs on
166 C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships.
168 Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for
173 All monikers and relationships are inflected using
174 L<Lingua::EN::Inflect::Phrase>, and there is more aggressive C<_id> stripping
175 from relationship names.
177 In general, there is very little difference between v5 and v6 schemas.
181 This mode is identical to C<v6> mode, except that monikerization of CamelCase
182 table names is also done correctly.
184 CamelCase column names in case-preserving mode will also be handled correctly
185 for relationship name inflection. See L</preserve_case>.
187 In this mode, CamelCase L</column_accessors> are normalized based on case
188 transition instead of just being lowercased, so C<FooId> becomes C<foo_id>.
190 If you don't have any CamelCase table or column names, you can upgrade without
191 breaking any of your code.
195 Dynamic schemas will always default to the 0.04XXX relationship names and won't
196 singularize Results for backward compatibility, to activate the new RelBuilder
197 and singularization put this in your C<Schema.pm> file:
199 __PACKAGE__->naming('current');
201 Or if you prefer to use 0.05XXX features but insure that nothing breaks in the
202 next major version upgrade:
204 __PACKAGE__->naming('v5');
208 By default POD will be generated for columns and relationships, using database
209 metadata for the text if available and supported.
211 Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only
212 supported for Postgres right now.
214 Set this to C<0> to turn off all POD generation.
216 =head2 pod_comment_mode
218 Controls where table comments appear in the generated POD. Smaller table
219 comments are appended to the C<NAME> section of the documentation, and larger
220 ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION>
221 section to be generated with the comment always, only use C<NAME>, or choose
222 the length threshold at which the comment is forced into the description.
228 Use C<NAME> section only.
232 Force C<DESCRIPTION> always.
236 Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the
241 =head2 pod_comment_spillover_length
243 When pod_comment_mode is set to C<auto>, this is the length of the comment at
244 which it will be forced into a separate description section.
248 =head2 relationship_attrs
250 Hashref of attributes to pass to each generated relationship, listed
251 by type. Also supports relationship type 'all', containing options to
252 pass to all generated relationships. Attributes set for more specific
253 relationship types override those set in 'all'.
257 relationship_attrs => {
258 belongs_to => { is_deferrable => 1 },
261 use this to make your foreign key constraints DEFERRABLE.
265 If set to true, each constructive L<DBIx::Class> statement the loader
266 decides to execute will be C<warn>-ed before execution.
270 Set the name of the schema to load (schema in the sense that your database
271 vendor means it). Does not currently support loading more than one schema
276 Only load tables matching regex. Best specified as a qr// regex.
280 Exclude tables matching regex. Best specified as a qr// regex.
284 Overrides the default table name to moniker translation. Can be either
285 a hashref of table keys and moniker values, or a coderef for a translator
286 function taking a single scalar table name argument and returning
287 a scalar moniker. If the hash entry does not exist, or the function
288 returns a false value, the code falls back to default behavior
291 The default behavior is to split on case transition and non-alphanumeric
292 boundaries, singularize the resulting phrase, then join the titlecased words
295 Table Name | Moniker Name
296 ---------------------------------
298 luser_group | LuserGroup
299 luser-opts | LuserOpt
300 stations_visited | StationVisited
301 routeChange | RouteChange
303 =head2 inflect_plural
305 Just like L</moniker_map> above (can be hash/code-ref, falls back to default
306 if hash key does not exist or coderef returns false), but acts as a map
307 for pluralizing relationship names. The default behavior is to utilize
308 L<Lingua::EN::Inflect::Number/to_PL>.
310 =head2 inflect_singular
312 As L</inflect_plural> above, but for singularizing relationship names.
313 Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>.
315 =head2 schema_base_class
317 Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
319 =head2 result_base_class
321 Base class for your table classes (aka result classes). Defaults to
324 =head2 additional_base_classes
326 List of additional base classes all of your table classes will use.
328 =head2 left_base_classes
330 List of additional base classes all of your table classes will use
331 that need to be leftmost.
333 =head2 additional_classes
335 List of additional classes which all of your table classes will use.
339 List of additional components to be loaded into all of your table
340 classes. A good example would be
341 L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime>
343 =head2 resultset_components
345 List of additional ResultSet components to be loaded into your table
346 classes. A good example would be C<AlwaysRS>. Component
347 C<ResultSetManager> will be automatically added to the above
348 C<components> list if this option is set.
350 =head2 use_namespaces
352 This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass
355 Generate result class names suitable for
356 L<DBIx::Class::Schema/load_namespaces> and call that instead of
357 L<DBIx::Class::Schema/load_classes>. When using this option you can also
358 specify any of the options for C<load_namespaces> (i.e. C<result_namespace>,
359 C<resultset_namespace>, C<default_resultset_class>), and they will be added
360 to the call (and the generated result class names adjusted appropriately).
362 =head2 dump_directory
364 This option is designed to be a tool to help you transition from this
365 loader to a manually-defined schema when you decide it's time to do so.
367 The value of this option is a perl libdir pathname. Within
368 that directory this module will create a baseline manual
369 L<DBIx::Class::Schema> module set, based on what it creates at runtime
372 The created schema class will have the same classname as the one on
373 which you are setting this option (and the ResultSource classes will be
374 based on this name as well).
376 Normally you wouldn't hard-code this setting in your schema class, as it
377 is meant for one-time manual usage.
379 See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the
380 recommended way to access this functionality.
382 =head2 dump_overwrite
384 Deprecated. See L</really_erase_my_files> below, which does *not* mean
385 the same thing as the old C<dump_overwrite> setting from previous releases.
387 =head2 really_erase_my_files
389 Default false. If true, Loader will unconditionally delete any existing
390 files before creating the new ones from scratch when dumping a schema to disk.
392 The default behavior is instead to only replace the top portion of the
393 file, up to and including the final stanza which contains
394 C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!>
395 leaving any customizations you placed after that as they were.
397 When C<really_erase_my_files> is not set, if the output file already exists,
398 but the aforementioned final stanza is not found, or the checksum
399 contained there does not match the generated contents, Loader will
400 croak and not touch the file.
402 You should really be using version control on your schema classes (and all
403 of the rest of your code for that matter). Don't blame me if a bug in this
404 code wipes something out when it shouldn't have, you've been warned.
406 =head2 overwrite_modifications
408 Default false. If false, when updating existing files, Loader will
409 refuse to modify any Loader-generated code that has been modified
410 since its last run (as determined by the checksum Loader put in its
413 If true, Loader will discard any manual modifications that have been
414 made to Loader-generated code.
416 Again, you should be using version control on your schema classes. Be
417 careful with this option.
419 =head2 custom_column_info
421 Hook for adding extra attributes to the
422 L<column_info|DBIx::Class::ResultSource/column_info> for a column.
424 Must be a coderef that returns a hashref with the extra attributes.
426 Receives the table name, column name and column_info.
430 custom_column_info => sub {
431 my ($table_name, $column_name, $column_info) = @_;
433 if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') {
434 return { is_snoopy => 1 };
438 This attribute can also be used to set C<inflate_datetime> on a non-datetime
439 column so it also receives the L</datetime_timezone> and/or L</datetime_locale>.
441 =head2 datetime_timezone
443 Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all
444 columns with the DATE/DATETIME/TIMESTAMP data_types.
446 =head2 datetime_locale
448 Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all
449 columns with the DATE/DATETIME/TIMESTAMP data_types.
453 File in Perl format, which should return a HASH reference, from which to read
458 Usually column names are lowercased, to make them easier to work with in
459 L<DBIx::Class>. This option lets you turn this behavior off, if the driver
462 Drivers for case sensitive databases like Sybase ASE or MSSQL with a
463 case-sensitive collation will turn this option on unconditionally.
465 Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support
470 None of these methods are intended for direct invocation by regular
471 users of L<DBIx::Class::Schema::Loader>. Some are proxied via
472 L<DBIx::Class::Schema::Loader>.

1855 be two entries for each table, the original name and the "normalized"
1856 name, in the case that the two are different (such as databases
1857 that like uppercase table names, or preserve your original mixed-case
1858 definitions, or what-have-you).
1862 Returns a hashref of table to class mappings. In some cases it will
1863 contain multiple entries per table for the original and normalized table
1864 names, as above in L</monikers>.
