88 | =head1 NAME |
89 | |
90 | DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation. |
91 | |
92 | =head1 SYNOPSIS |
93 | |
94 | See L<DBIx::Class::Schema::Loader> |
95 | |
96 | =head1 DESCRIPTION |
97 | |
98 | This is the base class for the storage-specific C<DBIx::Class::Schema::*> |
99 | classes, and implements the common functionality between them. |
100 | |
101 | =head1 CONSTRUCTOR OPTIONS |
102 | |
103 | These constructor options are the base options for |
29ddb54c |
104 | L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are: |
3953cbee |
105 | |
59cfa251 |
106 | =head2 skip_relationships |
996be9ee |
107 | |
59cfa251 |
108 | Skip setting up relationships. The default is to attempt the loading |
109 | of relationships. |
996be9ee |
110 | |
0ca61324 |
111 | =head2 skip_load_external |
112 | |
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. |
115 | |
9a95164d |
116 | =head2 naming |
117 | |
ecf930e6 |
118 | Static schemas (ones dumped to disk) will, by default, use the new-style |
9a95164d |
119 | relationship names and singularized Results, unless you're overwriting an |
ecf930e6 |
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. |
9a95164d |
123 | |
124 | Specifying |
125 | |
ecf930e6 |
126 | naming => 'current' |
9a95164d |
127 | |
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. |
131 | |
132 | The option also takes a hashref: |
133 | |
f3cfe4e6 |
134 | naming => { relationships => 'v8', monikers => 'v8' } |

153 | |
154 | The values can be: |
155 | |
156 | =over 4 |
157 | |
158 | =item current |
159 | |
ecf930e6 |
160 | Latest style, whatever that happens to be. |
161 | |
162 | =item v4 |
163 | |
164 | Unsingularlized monikers, C<has_many> only relationships with no _id stripping. |
9a95164d |
165 | |
166 | =item v5 |
167 | |
ecf930e6 |
168 | Monikers singularized as whole words, C<might_have> relationships for FKs on |
169 | C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships. |
9a95164d |
170 | |
ecf930e6 |
171 | Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for |
172 | the v5 RelBuilder. |
173 | |
174 | =item v6 |
9a95164d |
175 | |
19b7d71c |
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. |
ecf930e6 |
179 | |
180 | In general, there is very little difference between v5 and v6 schemas. |
9a95164d |
181 | |
9990e58f |
182 | =item v7 |
183 | |
184 | This mode is identical to C<v6> mode, except that monikerization of CamelCase |
185 | table names is also done correctly. |
186 | |
0c1d5b47 |
187 | CamelCase column names in case-preserving mode will also be handled correctly |
188 | for relationship name inflection. See L</preserve_case>. |
19b7d71c |
189 | |
f3a657ef |
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>. |
192 | |
19b7d71c |
193 | If you don't have any CamelCase table or column names, you can upgrade without |
194 | breaking any of your code. |
9990e58f |
195 | |
f3cfe4e6 |
196 | =item v8 |
197 | |
198 | This mode tries harder to not have collisions between column accessors and |
199 | belongs_to relationship accessors. |
200 | |
9a95164d |
201 | =back |
202 | |
203 | Dynamic schemas will always default to the 0.04XXX relationship names and won't |
204 | singularize Results for backward compatibility, to activate the new RelBuilder |
205 | and singularization put this in your C<Schema.pm> file: |
206 | |
207 | __PACKAGE__->naming('current'); |
208 | |
f3cfe4e6 |
209 | Or if you prefer to use 0.08XXX features but insure that nothing breaks in the |
9a95164d |
210 | next major version upgrade: |
211 | |
f3cfe4e6 |
212 | __PACKAGE__->naming('v8'); |
9a95164d |
213 | |
492dce8d |
214 | =head2 generate_pod |
215 | |
216 | By default POD will be generated for columns and relationships, using database |
7f2de014 |
217 | metadata for the text if available and supported. |
218 | |
219 | Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only |
220 | supported for Postgres right now. |
492dce8d |
221 | |
222 | Set this to C<0> to turn off all POD generation. |
223 | |
43b982ea |
224 | =head2 pod_comment_mode |
225 | |
f7976fea |
226 | Controls where table comments appear in the generated POD. Smaller table |
227 | comments are appended to the C<NAME> section of the documentation, and larger |
228 | ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION> |
229 | section to be generated with the comment always, only use C<NAME>, or choose |
230 | the length threshold at which the comment is forced into the description. |
43b982ea |
231 | |
34896b5e |
232 | =over 4 |
233 | |
234 | =item name |
235 | |
236 | Use C<NAME> section only. |
237 | |
238 | =item description |
239 | |
240 | Force C<DESCRIPTION> always. |
241 | |
242 | =item auto |
243 | |
244 | Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the |
245 | default. |
246 | |
247 | =back |
43b982ea |
248 | |
249 | =head2 pod_comment_spillover_length |
250 | |
251 | When pod_comment_mode is set to C<auto>, this is the length of the comment at |
252 | which it will be forced into a separate description section. |
253 | |
254 | The default is C<60> |
255 | |
c8c27020 |
256 | =head2 relationship_attrs |
257 | |
258 | Hashref of attributes to pass to each generated relationship, listed |
259 | by type. Also supports relationship type 'all', containing options to |
260 | pass to all generated relationships. Attributes set for more specific |
261 | relationship types override those set in 'all'. |
262 | |
263 | For example: |
264 | |
265 | relationship_attrs => { |
6818ce9f |
266 | belongs_to => { is_deferrable => 1 }, |
c8c27020 |
267 | }, |
268 | |
6818ce9f |
269 | use this to make your foreign key constraints DEFERRABLE. |
c8c27020 |
270 | |
996be9ee |
271 | =head2 debug |
272 | |
273 | If set to true, each constructive L<DBIx::Class> statement the loader |
274 | decides to execute will be C<warn>-ed before execution. |
275 | |
d65cda9e |
276 | =head2 db_schema |
277 | |
278 | Set the name of the schema to load (schema in the sense that your database |
279 | vendor means it). Does not currently support loading more than one schema |
280 | name. |
281 | |
996be9ee |
282 | =head2 constraint |
283 | |
284 | Only load tables matching regex. Best specified as a qr// regex. |
285 | |
286 | =head2 exclude |
287 | |
288 | Exclude tables matching regex. Best specified as a qr// regex. |
289 | |
290 | =head2 moniker_map |
291 | |
8f9d7ce5 |
292 | Overrides the default table name to moniker translation. Can be either |
293 | a hashref of table keys and moniker values, or a coderef for a translator |
996be9ee |
294 | function taking a single scalar table name argument and returning |
295 | a scalar moniker. If the hash entry does not exist, or the function |
296 | returns a false value, the code falls back to default behavior |
297 | for that table name. |
298 | |
9990e58f |
299 | The default behavior is to split on case transition and non-alphanumeric |
300 | boundaries, singularize the resulting phrase, then join the titlecased words |
301 | together. Examples: |
996be9ee |
302 | |
9990e58f |
303 | Table Name | Moniker Name |
304 | --------------------------------- |
305 | luser | Luser |
306 | luser_group | LuserGroup |
307 | luser-opts | LuserOpt |
308 | stations_visited | StationVisited |
309 | routeChange | RouteChange |
996be9ee |
310 | |
311 | =head2 inflect_plural |
312 | |
313 | Just like L</moniker_map> above (can be hash/code-ref, falls back to default |
314 | if hash key does not exist or coderef returns false), but acts as a map |
315 | for pluralizing relationship names. The default behavior is to utilize |
316 | L<Lingua::EN::Inflect::Number/to_PL>. |
317 | |
318 | =head2 inflect_singular |
319 | |
320 | As L</inflect_plural> above, but for singularizing relationship names. |
321 | Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>. |
322 | |
9c9c2f2b |
323 | =head2 schema_base_class |
324 | |
325 | Base class for your schema classes. Defaults to 'DBIx::Class::Schema'. |
326 | |
327 | =head2 result_base_class |
328 | |
2229729e |
329 | Base class for your table classes (aka result classes). Defaults to |
330 | 'DBIx::Class::Core'. |
9c9c2f2b |
331 | |
996be9ee |
332 | =head2 additional_base_classes |
333 | |
334 | List of additional base classes all of your table classes will use. |
335 | |
336 | =head2 left_base_classes |
337 | |
338 | List of additional base classes all of your table classes will use |
339 | that need to be leftmost. |
340 | |
341 | =head2 additional_classes |
342 | |
343 | List of additional classes which all of your table classes will use. |
344 | |
345 | =head2 components |
346 | |
347 | List of additional components to be loaded into all of your table |
eccc52fe |
348 | classes. A good example would be |
349 | L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime> |
996be9ee |
350 | |
351 | =head2 resultset_components |
352 | |
8f9d7ce5 |
353 | List of additional ResultSet components to be loaded into your table |
996be9ee |
354 | classes. A good example would be C<AlwaysRS>. Component |
355 | C<ResultSetManager> will be automatically added to the above |
356 | C<components> list if this option is set. |
357 | |
f44ecc2f |
358 | =head2 use_namespaces |
359 | |
f22644d7 |
360 | This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass |
361 | a C<0>. |
362 | |
f44ecc2f |
363 | Generate result class names suitable for |
364 | L<DBIx::Class::Schema/load_namespaces> and call that instead of |
365 | L<DBIx::Class::Schema/load_classes>. When using this option you can also |
366 | specify any of the options for C<load_namespaces> (i.e. C<result_namespace>, |
367 | C<resultset_namespace>, C<default_resultset_class>), and they will be added |
368 | to the call (and the generated result class names adjusted appropriately). |
369 | |
996be9ee |
370 | =head2 dump_directory |
371 | |
372 | This option is designed to be a tool to help you transition from this |
373 | loader to a manually-defined schema when you decide it's time to do so. |
374 | |
375 | The value of this option is a perl libdir pathname. Within |
376 | that directory this module will create a baseline manual |
377 | L<DBIx::Class::Schema> module set, based on what it creates at runtime |
378 | in memory. |
379 | |
380 | The created schema class will have the same classname as the one on |
381 | which you are setting this option (and the ResultSource classes will be |
7cab3ab7 |
382 | based on this name as well). |
996be9ee |
383 | |
8f9d7ce5 |
384 | Normally you wouldn't hard-code this setting in your schema class, as it |
996be9ee |
385 | is meant for one-time manual usage. |
386 | |
387 | See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the |
388 | recommended way to access this functionality. |
389 | |
d65cda9e |
390 | =head2 dump_overwrite |
391 | |
28b4691d |
392 | Deprecated. See L</really_erase_my_files> below, which does *not* mean |
393 | the same thing as the old C<dump_overwrite> setting from previous releases. |
394 | |
395 | =head2 really_erase_my_files |
396 | |
7cab3ab7 |
397 | Default false. If true, Loader will unconditionally delete any existing |
398 | files before creating the new ones from scratch when dumping a schema to disk. |
399 | |
400 | The default behavior is instead to only replace the top portion of the |
401 | file, up to and including the final stanza which contains |
402 | C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!> |
403 | leaving any customizations you placed after that as they were. |
404 | |
28b4691d |
405 | When C<really_erase_my_files> is not set, if the output file already exists, |
7cab3ab7 |
406 | but the aforementioned final stanza is not found, or the checksum |
407 | contained there does not match the generated contents, Loader will |
408 | croak and not touch the file. |
d65cda9e |
409 | |
28b4691d |
410 | You should really be using version control on your schema classes (and all |
411 | of the rest of your code for that matter). Don't blame me if a bug in this |
412 | code wipes something out when it shouldn't have, you've been warned. |
413 | |
639a1367 |
414 | =head2 overwrite_modifications |
415 | |
416 | Default false. If false, when updating existing files, Loader will |
417 | refuse to modify any Loader-generated code that has been modified |
418 | since its last run (as determined by the checksum Loader put in its |
419 | comment lines). |
420 | |
421 | If true, Loader will discard any manual modifications that have been |
422 | made to Loader-generated code. |
423 | |
424 | Again, you should be using version control on your schema classes. Be |
425 | careful with this option. |
426 | |
3a368709 |
427 | =head2 custom_column_info |
428 | |
d67d058e |
429 | Hook for adding extra attributes to the |
430 | L<column_info|DBIx::Class::ResultSource/column_info> for a column. |
431 | |
432 | Must be a coderef that returns a hashref with the extra attributes. |
433 | |
434 | Receives the table name, column name and column_info. |
435 | |
436 | For example: |
437 | |
438 | custom_column_info => sub { |
439 | my ($table_name, $column_name, $column_info) = @_; |
440 | |
441 | if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') { |
442 | return { is_snoopy => 1 }; |
443 | } |
444 | }, |
3a368709 |
445 | |
d67d058e |
446 | This attribute can also be used to set C<inflate_datetime> on a non-datetime |
447 | column so it also receives the L</datetime_timezone> and/or L</datetime_locale>. |
3a368709 |
448 | |
42e785fa |
449 | =head2 datetime_timezone |
450 | |
d67d058e |
451 | Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all |
452 | columns with the DATE/DATETIME/TIMESTAMP data_types. |
42e785fa |

454 | =head2 datetime_locale |
455 | |
d67d058e |
456 | Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all |
457 | columns with the DATE/DATETIME/TIMESTAMP data_types. |
42e785fa |
458 | |
7ffafa37 |
459 | =head2 config_file |
73099af4 |
460 | |
461 | File in Perl format, which should return a HASH reference, from which to read |
462 | loader options. |
463 | |
7ffafa37 |
464 | =head2 preserve_case |
bc1cb85e |
465 | |
466 | Usually column names are lowercased, to make them easier to work with in |
467 | L<DBIx::Class>. This option lets you turn this behavior off, if the driver |
468 | supports it. |
469 | |
470 | Drivers for case sensitive databases like Sybase ASE or MSSQL with a |
471 | case-sensitive collation will turn this option on unconditionally. |
472 | |
473 | Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support |
474 | setting this option. |
475 | |
7ffafa37 |
476 | =head2 qualify_objects |
69219349 |
477 | |
478 | Set to true to prepend the L</db_schema> to table names for C<< |
479 | __PACKAGE__->table >> calls, and to some other things like Oracle sequences. |
480 | |
7d0ea6b9 |
481 | =head2 use_moose |
482 | |
483 | Creates Schema and Result classes that use L<Moose>, L<MooseX::NonMoose> and |
1336ac63 |
484 | L<namespace::autoclean>. The default content after the md5 sum also makes the |
485 | classes immutable. |
7d0ea6b9 |
486 | |
487 | It is safe to upgrade your existing Schema to this option. |
