87 | =head1 NAME |
88 | |
89 | DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation. |
90 | |
91 | =head1 SYNOPSIS |
92 | |
93 | See L<DBIx::Class::Schema::Loader> |
94 | |
95 | =head1 DESCRIPTION |
96 | |
97 | This is the base class for the storage-specific C<DBIx::Class::Schema::*> |
98 | classes, and implements the common functionality between them. |
99 | |
100 | =head1 CONSTRUCTOR OPTIONS |
101 | |
102 | These constructor options are the base options for |
29ddb54c |
103 | L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are: |
3953cbee |
104 | |
59cfa251 |
105 | =head2 skip_relationships |
996be9ee |
106 | |
59cfa251 |
107 | Skip setting up relationships. The default is to attempt the loading |
108 | of relationships. |
996be9ee |
109 | |
0ca61324 |
110 | =head2 skip_load_external |
111 | |
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. |
114 | |
9a95164d |
115 | =head2 naming |
116 | |
ecf930e6 |
117 | Static schemas (ones dumped to disk) will, by default, use the new-style |
9a95164d |
118 | relationship names and singularized Results, unless you're overwriting an |
ecf930e6 |
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. |
9a95164d |
122 | |
123 | Specifying |
124 | |
ecf930e6 |
125 | naming => 'current' |
9a95164d |
126 | |
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. |
130 | |
131 | The option also takes a hashref: |
132 | |
2a1ff2ee |
133 | naming => { relationships => 'v7', monikers => 'v7' } |
a8d229ff |

150 | |
a8d229ff |
151 | =back |
9a95164d |
152 | |
153 | The values can be: |
154 | |
155 | =over 4 |
156 | |
157 | =item current |
158 | |
ecf930e6 |
159 | Latest style, whatever that happens to be. |
160 | |
161 | =item v4 |
162 | |
163 | Unsingularlized monikers, C<has_many> only relationships with no _id stripping. |
9a95164d |
164 | |
165 | =item v5 |
166 | |
ecf930e6 |
167 | Monikers singularized as whole words, C<might_have> relationships for FKs on |
168 | C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships. |
9a95164d |
169 | |
ecf930e6 |
170 | Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for |
171 | the v5 RelBuilder. |
172 | |
173 | =item v6 |
9a95164d |
174 | |
19b7d71c |
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. |
ecf930e6 |
178 | |
179 | In general, there is very little difference between v5 and v6 schemas. |
9a95164d |
180 | |
9990e58f |
181 | =item v7 |
182 | |
183 | This mode is identical to C<v6> mode, except that monikerization of CamelCase |
184 | table names is also done correctly. |
185 | |
0c1d5b47 |
186 | CamelCase column names in case-preserving mode will also be handled correctly |
187 | for relationship name inflection. See L</preserve_case>. |
19b7d71c |
188 | |
f3a657ef |
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>. |
191 | |
19b7d71c |
192 | If you don't have any CamelCase table or column names, you can upgrade without |
193 | breaking any of your code. |
9990e58f |
194 | |
9a95164d |
195 | =back |
196 | |
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: |
200 | |
201 | __PACKAGE__->naming('current'); |
202 | |
203 | Or if you prefer to use 0.05XXX features but insure that nothing breaks in the |
204 | next major version upgrade: |
205 | |
206 | __PACKAGE__->naming('v5'); |
207 | |
492dce8d |
208 | =head2 generate_pod |
209 | |
210 | By default POD will be generated for columns and relationships, using database |
7f2de014 |
211 | metadata for the text if available and supported. |
212 | |
213 | Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only |
214 | supported for Postgres right now. |
492dce8d |
215 | |
216 | Set this to C<0> to turn off all POD generation. |
217 | |
43b982ea |
218 | =head2 pod_comment_mode |
219 | |
f7976fea |
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. |
43b982ea |
225 | |
34896b5e |
226 | =over 4 |
227 | |
228 | =item name |
229 | |
230 | Use C<NAME> section only. |
231 | |
232 | =item description |
233 | |
234 | Force C<DESCRIPTION> always. |
235 | |
236 | =item auto |
237 | |
238 | Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the |
239 | default. |
240 | |
241 | =back |
43b982ea |
242 | |
243 | =head2 pod_comment_spillover_length |
244 | |
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. |
247 | |
248 | The default is C<60> |
249 | |
c8c27020 |
250 | =head2 relationship_attrs |
251 | |
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'. |
256 | |
257 | For example: |
258 | |
259 | relationship_attrs => { |
6818ce9f |
260 | belongs_to => { is_deferrable => 1 }, |
c8c27020 |
261 | }, |
262 | |
6818ce9f |
263 | use this to make your foreign key constraints DEFERRABLE. |
c8c27020 |
264 | |
996be9ee |
265 | =head2 debug |
266 | |
267 | If set to true, each constructive L<DBIx::Class> statement the loader |
268 | decides to execute will be C<warn>-ed before execution. |
269 | |
d65cda9e |
270 | =head2 db_schema |
271 | |
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 |
274 | name. |
275 | |
996be9ee |
276 | =head2 constraint |
277 | |
278 | Only load tables matching regex. Best specified as a qr// regex. |
279 | |
280 | =head2 exclude |
281 | |
282 | Exclude tables matching regex. Best specified as a qr// regex. |
283 | |
284 | =head2 moniker_map |
285 | |
8f9d7ce5 |
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 |
996be9ee |
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 |
291 | for that table name. |
292 | |
9990e58f |
293 | The default behavior is to split on case transition and non-alphanumeric |
294 | boundaries, singularize the resulting phrase, then join the titlecased words |
295 | together. Examples: |
996be9ee |
296 | |
9990e58f |
297 | Table Name | Moniker Name |
298 | --------------------------------- |
299 | luser | Luser |
300 | luser_group | LuserGroup |
301 | luser-opts | LuserOpt |
302 | stations_visited | StationVisited |
303 | routeChange | RouteChange |
996be9ee |
304 | |
305 | =head2 inflect_plural |
306 | |
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>. |
311 | |
312 | =head2 inflect_singular |
313 | |
314 | As L</inflect_plural> above, but for singularizing relationship names. |
315 | Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>. |
316 | |
9c9c2f2b |
317 | =head2 schema_base_class |
318 | |
319 | Base class for your schema classes. Defaults to 'DBIx::Class::Schema'. |
320 | |
321 | =head2 result_base_class |
322 | |
2229729e |
323 | Base class for your table classes (aka result classes). Defaults to |
324 | 'DBIx::Class::Core'. |
9c9c2f2b |
325 | |
996be9ee |
326 | =head2 additional_base_classes |
327 | |
328 | List of additional base classes all of your table classes will use. |
329 | |
330 | =head2 left_base_classes |
331 | |
332 | List of additional base classes all of your table classes will use |
333 | that need to be leftmost. |
334 | |
335 | =head2 additional_classes |
336 | |
337 | List of additional classes which all of your table classes will use. |
338 | |
339 | =head2 components |
340 | |
341 | List of additional components to be loaded into all of your table |
eccc52fe |
342 | classes. A good example would be |
343 | L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime> |
996be9ee |
344 | |
345 | =head2 resultset_components |
346 | |
8f9d7ce5 |
347 | List of additional ResultSet components to be loaded into your table |
996be9ee |
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. |
351 | |
f44ecc2f |
352 | =head2 use_namespaces |
353 | |
f22644d7 |
354 | This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass |
355 | a C<0>. |
356 | |
f44ecc2f |
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). |
363 | |
996be9ee |
364 | =head2 dump_directory |
365 | |
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. |
368 | |
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 |
372 | in memory. |
373 | |
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 |
7cab3ab7 |
376 | based on this name as well). |
996be9ee |
377 | |
8f9d7ce5 |
378 | Normally you wouldn't hard-code this setting in your schema class, as it |
996be9ee |
379 | is meant for one-time manual usage. |
380 | |
381 | See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the |
382 | recommended way to access this functionality. |
383 | |
d65cda9e |
384 | =head2 dump_overwrite |
385 | |
28b4691d |
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. |
388 | |
389 | =head2 really_erase_my_files |
390 | |
7cab3ab7 |
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. |
393 | |
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. |
398 | |
28b4691d |
399 | When C<really_erase_my_files> is not set, if the output file already exists, |
7cab3ab7 |
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. |
d65cda9e |
403 | |
28b4691d |
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. |
407 | |
639a1367 |
408 | =head2 overwrite_modifications |
409 | |
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 |
413 | comment lines). |
414 | |
415 | If true, Loader will discard any manual modifications that have been |
416 | made to Loader-generated code. |
417 | |
418 | Again, you should be using version control on your schema classes. Be |
419 | careful with this option. |
420 | |
3a368709 |
421 | =head2 custom_column_info |
422 | |
d67d058e |
423 | Hook for adding extra attributes to the |
424 | L<column_info|DBIx::Class::ResultSource/column_info> for a column. |
425 | |
426 | Must be a coderef that returns a hashref with the extra attributes. |
427 | |
428 | Receives the table name, column name and column_info. |
429 | |
430 | For example: |
431 | |
432 | custom_column_info => sub { |
433 | my ($table_name, $column_name, $column_info) = @_; |
434 | |
435 | if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') { |
436 | return { is_snoopy => 1 }; |
437 | } |
438 | }, |
3a368709 |
439 | |
d67d058e |
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>. |
3a368709 |
442 | |
42e785fa |
443 | =head2 datetime_timezone |
444 | |
d67d058e |
445 | Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all |
446 | columns with the DATE/DATETIME/TIMESTAMP data_types. |
42e785fa |
447 | |
448 | =head2 datetime_locale |
449 | |
d67d058e |
450 | Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all |
451 | columns with the DATE/DATETIME/TIMESTAMP data_types. |
42e785fa |
452 | |
73099af4 |
453 | =head1 config_file |

458 | =head1 preserve_case |
459 | |
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 |
462 | supports it. |
463 | |
464 | Drivers for case sensitive databases like Sybase ASE or MSSQL with a |
465 | case-sensitive collation will turn this option on unconditionally. |
466 | |
467 | Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support |
468 | setting this option. |

470 | =head1 qualify_objects |

472 | Set to true to prepend the L</db_schema> to table names for C<< |
