88 DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.
92 See L<DBIx::Class::Schema::Loader>
96 This is the base class for the storage-specific C<DBIx::Class::Schema::*>
97 classes, and implements the common functionality between them.
99 =head1 CONSTRUCTOR OPTIONS
101 These constructor options are the base options for
102 L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are:
104 =head2 skip_relationships
106 Skip setting up relationships. The default is to attempt the loading
109 =head2 skip_load_external
111 Skip loading of other classes in @INC. The default is to merge all other classes
112 with the same name found in @INC into the schema file we are creating.
116 Static schemas (ones dumped to disk) will, by default, use the new-style
117 relationship names and singularized Results, unless you're overwriting an
118 existing dump made by an older version of L<DBIx::Class::Schema::Loader>, in
119 which case the backward compatible RelBuilder will be activated, and the
120 appropriate monikerization used.
126 will disable the backward-compatible RelBuilder and use
127 the new-style relationship names along with singularized Results, even when
128 overwriting a dump made with an earlier version.
130 The option also takes a hashref:
132 naming => { relationships => 'v6', monikers => 'v6' }
140 How to name relationship accessors.
144 How to name Result classes.
146 =item column_accessors
148 How to name column accessors in Result classes.
158 Latest style, whatever that happens to be.
162 Unsingularlized monikers, C<has_many> only relationships with no _id stripping.
166 Monikers singularized as whole words, C<might_have> relationships for FKs on
167 C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships.
169 Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for
174 All monikers and relationships are inflected using
175 L<Lingua::EN::Inflect::Phrase>, and there is more aggressive C<_id> stripping
176 from relationship names.
178 In general, there is very little difference between v5 and v6 schemas.
182 This mode is identical to C<v6> mode, except that monikerization of CamelCase
183 table names is also done correctly.
185 CamelCase column names in case-preserving mode will also be handled correctly
186 for relationship name inflection. See L</preserve_case>.
188 In this mode, CamelCase L</column_accessors> are normalized based on case
189 transition instead of just being lowercased, so C<FooId> becomes C<foo_id>.
191 If you don't have any CamelCase table or column names, you can upgrade without
192 breaking any of your code.
196 Dynamic schemas will always default to the 0.04XXX relationship names and won't
197 singularize Results for backward compatibility, to activate the new RelBuilder
198 and singularization put this in your C<Schema.pm> file:
200 __PACKAGE__->naming('current');
202 Or if you prefer to use 0.05XXX features but insure that nothing breaks in the
203 next major version upgrade:
205 __PACKAGE__->naming('v5');
209 By default POD will be generated for columns and relationships, using database
210 metadata for the text if available and supported.
212 Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only
213 supported for Postgres right now.
215 Set this to C<0> to turn off all POD generation.
217 =head2 pod_comment_mode
219 Controls where table comments appear in the generated POD. Smaller table
220 comments are appended to the C<NAME> section of the documentation, and larger
221 ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION>
222 section to be generated with the comment always, only use C<NAME>, or choose
223 the length threshold at which the comment is forced into the description.
229 Use C<NAME> section only.
233 Force C<DESCRIPTION> always.
237 Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the
242 =head2 pod_comment_spillover_length
244 When pod_comment_mode is set to C<auto>, this is the length of the comment at
245 which it will be forced into a separate description section.
249 =head2 relationship_attrs
251 Hashref of attributes to pass to each generated relationship, listed
252 by type. Also supports relationship type 'all', containing options to
253 pass to all generated relationships. Attributes set for more specific
254 relationship types override those set in 'all'.
258 relationship_attrs => {
259 belongs_to => { is_deferrable => 1 },
262 use this to make your foreign key constraints DEFERRABLE.
266 If set to true, each constructive L<DBIx::Class> statement the loader
267 decides to execute will be C<warn>-ed before execution.
271 Set the name of the schema to load (schema in the sense that your database
272 vendor means it). Does not currently support loading more than one schema
277 Only load tables matching regex. Best specified as a qr// regex.
281 Exclude tables matching regex. Best specified as a qr// regex.
285 Overrides the default table name to moniker translation. Can be either
286 a hashref of table keys and moniker values, or a coderef for a translator
287 function taking a single scalar table name argument and returning
288 a scalar moniker. If the hash entry does not exist, or the function
289 returns a false value, the code falls back to default behavior
292 The default behavior is to split on case transition and non-alphanumeric
293 boundaries, singularize the resulting phrase, then join the titlecased words
296 Table Name | Moniker Name
297 ---------------------------------
299 luser_group | LuserGroup
300 luser-opts | LuserOpt
301 stations_visited | StationVisited
302 routeChange | RouteChange
304 =head2 inflect_plural
306 Just like L</moniker_map> above (can be hash/code-ref, falls back to default
307 if hash key does not exist or coderef returns false), but acts as a map
308 for pluralizing relationship names. The default behavior is to utilize
309 L<Lingua::EN::Inflect::Number/to_PL>.
311 =head2 inflect_singular
313 As L</inflect_plural> above, but for singularizing relationship names.
314 Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>.
316 =head2 schema_base_class
318 Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
320 =head2 result_base_class
322 Base class for your table classes (aka result classes). Defaults to
325 =head2 additional_base_classes
327 List of additional base classes all of your table classes will use.
329 =head2 left_base_classes
331 List of additional base classes all of your table classes will use
332 that need to be leftmost.
334 =head2 additional_classes
336 List of additional classes which all of your table classes will use.
340 List of additional components to be loaded into all of your table
341 classes. A good example would be
342 L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime>
344 =head2 resultset_components
346 List of additional ResultSet components to be loaded into your table
347 classes. A good example would be C<AlwaysRS>. Component
348 C<ResultSetManager> will be automatically added to the above
349 C<components> list if this option is set.
351 =head2 use_namespaces
353 This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass
356 Generate result class names suitable for
357 L<DBIx::Class::Schema/load_namespaces> and call that instead of
358 L<DBIx::Class::Schema/load_classes>. When using this option you can also
359 specify any of the options for C<load_namespaces> (i.e. C<result_namespace>,
360 C<resultset_namespace>, C<default_resultset_class>), and they will be added
361 to the call (and the generated result class names adjusted appropriately).
363 =head2 dump_directory
365 This option is designed to be a tool to help you transition from this
366 loader to a manually-defined schema when you decide it's time to do so.
368 The value of this option is a perl libdir pathname. Within
369 that directory this module will create a baseline manual
370 L<DBIx::Class::Schema> module set, based on what it creates at runtime
373 The created schema class will have the same classname as the one on
374 which you are setting this option (and the ResultSource classes will be
375 based on this name as well).
377 Normally you wouldn't hard-code this setting in your schema class, as it
378 is meant for one-time manual usage.
380 See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the
381 recommended way to access this functionality.
383 =head2 dump_overwrite
385 Deprecated. See L</really_erase_my_files> below, which does *not* mean
386 the same thing as the old C<dump_overwrite> setting from previous releases.
388 =head2 really_erase_my_files
390 Default false. If true, Loader will unconditionally delete any existing
391 files before creating the new ones from scratch when dumping a schema to disk.
393 The default behavior is instead to only replace the top portion of the
394 file, up to and including the final stanza which contains
395 C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!>
396 leaving any customizations you placed after that as they were.
398 When C<really_erase_my_files> is not set, if the output file already exists,
399 but the aforementioned final stanza is not found, or the checksum
400 contained there does not match the generated contents, Loader will
401 croak and not touch the file.
403 You should really be using version control on your schema classes (and all
404 of the rest of your code for that matter). Don't blame me if a bug in this
405 code wipes something out when it shouldn't have, you've been warned.
407 =head2 overwrite_modifications
409 Default false. If false, when updating existing files, Loader will
410 refuse to modify any Loader-generated code that has been modified
411 since its last run (as determined by the checksum Loader put in its
414 If true, Loader will discard any manual modifications that have been
415 made to Loader-generated code.
417 Again, you should be using version control on your schema classes. Be
418 careful with this option.
420 =head2 custom_column_info
422 Hook for adding extra attributes to the
423 L<column_info|DBIx::Class::ResultSource/column_info> for a column.
425 Must be a coderef that returns a hashref with the extra attributes.
427 Receives the table name, column name and column_info.
431 custom_column_info => sub {
432 my ($table_name, $column_name, $column_info) = @_;
434 if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') {
435 return { is_snoopy => 1 };
439 This attribute can also be used to set C<inflate_datetime> on a non-datetime
440 column so it also receives the L</datetime_timezone> and/or L</datetime_locale>.
442 =head2 datetime_timezone
444 Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all
445 columns with the DATE/DATETIME/TIMESTAMP data_types.
447 =head2 datetime_locale
449 Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all
450 columns with the DATE/DATETIME/TIMESTAMP data_types.
454 File in Perl format, which should return a HASH reference, from which to read
459 Usually column names are lowercased, to make them easier to work with in
460 L<DBIx::Class>. This option lets you turn this behavior off, if the driver
463 Drivers for case sensitive databases like Sybase ASE or MSSQL with a
464 case-sensitive collation will turn this option on unconditionally.
466 Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support
471 None of these methods are intended for direct invocation by regular
472 users of L<DBIx::Class::Schema::Loader>. Some are proxied via
473 L<DBIx::Class::Schema::Loader>.

1862 be two entries for each table, the original name and the "normalized"
1863 name, in the case that the two are different (such as databases
1864 that like uppercase table names, or preserve your original mixed-case
1865 definitions, or what-have-you).
1869 Returns a hashref of table to class mappings. In some cases it will
1870 contain multiple entries per table for the original and normalized table
1871 names, as above in L</monikers>.
