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 | |
2a1ff2ee |
134 | naming => { relationships => 'v7', monikers => 'v7' } |
a8d229ff |

9a95164d |
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 | |
9a95164d |
196 | =back |
197 | |
198 | Dynamic schemas will always default to the 0.04XXX relationship names and won't |
199 | singularize Results for backward compatibility, to activate the new RelBuilder |
200 | and singularization put this in your C<Schema.pm> file: |
201 | |
202 | __PACKAGE__->naming('current'); |
203 | |
204 | Or if you prefer to use 0.05XXX features but insure that nothing breaks in the |
205 | next major version upgrade: |
206 | |
207 | __PACKAGE__->naming('v5'); |
208 | |
492dce8d |
209 | =head2 generate_pod |
210 | |
211 | By default POD will be generated for columns and relationships, using database |
7f2de014 |
212 | metadata for the text if available and supported. |
213 | |
214 | Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only |
215 | supported for Postgres right now. |
492dce8d |
216 | |
217 | Set this to C<0> to turn off all POD generation. |
218 | |
43b982ea |
219 | =head2 pod_comment_mode |
220 | |
f7976fea |
221 | Controls where table comments appear in the generated POD. Smaller table |
222 | comments are appended to the C<NAME> section of the documentation, and larger |
223 | ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION> |
224 | section to be generated with the comment always, only use C<NAME>, or choose |
225 | the length threshold at which the comment is forced into the description. |
43b982ea |
226 | |
34896b5e |
227 | =over 4 |
228 | |
229 | =item name |
230 | |
231 | Use C<NAME> section only. |
232 | |
233 | =item description |
234 | |
235 | Force C<DESCRIPTION> always. |
236 | |
237 | =item auto |
238 | |
239 | Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the |
240 | default. |
241 | |
242 | =back |
43b982ea |
243 | |
244 | =head2 pod_comment_spillover_length |
245 | |
246 | When pod_comment_mode is set to C<auto>, this is the length of the comment at |
247 | which it will be forced into a separate description section. |
248 | |
249 | The default is C<60> |
250 | |
c8c27020 |
251 | =head2 relationship_attrs |
252 | |
253 | Hashref of attributes to pass to each generated relationship, listed |
254 | by type. Also supports relationship type 'all', containing options to |
255 | pass to all generated relationships. Attributes set for more specific |
256 | relationship types override those set in 'all'. |
257 | |
258 | For example: |
259 | |
260 | relationship_attrs => { |
6818ce9f |
261 | belongs_to => { is_deferrable => 1 }, |
c8c27020 |
262 | }, |
263 | |
6818ce9f |
264 | use this to make your foreign key constraints DEFERRABLE. |
c8c27020 |
265 | |
996be9ee |
266 | =head2 debug |
267 | |
268 | If set to true, each constructive L<DBIx::Class> statement the loader |
269 | decides to execute will be C<warn>-ed before execution. |
270 | |
d65cda9e |
271 | =head2 db_schema |
272 | |
273 | Set the name of the schema to load (schema in the sense that your database |
274 | vendor means it). Does not currently support loading more than one schema |
275 | name. |
276 | |
996be9ee |
277 | =head2 constraint |
278 | |
279 | Only load tables matching regex. Best specified as a qr// regex. |
280 | |
281 | =head2 exclude |
282 | |
283 | Exclude tables matching regex. Best specified as a qr// regex. |
284 | |
285 | =head2 moniker_map |
286 | |
8f9d7ce5 |
287 | Overrides the default table name to moniker translation. Can be either |
288 | a hashref of table keys and moniker values, or a coderef for a translator |
996be9ee |
289 | function taking a single scalar table name argument and returning |
290 | a scalar moniker. If the hash entry does not exist, or the function |
291 | returns a false value, the code falls back to default behavior |
292 | for that table name. |
293 | |
9990e58f |
294 | The default behavior is to split on case transition and non-alphanumeric |
295 | boundaries, singularize the resulting phrase, then join the titlecased words |
296 | together. Examples: |
996be9ee |
297 | |
9990e58f |
298 | Table Name | Moniker Name |
299 | --------------------------------- |
300 | luser | Luser |
301 | luser_group | LuserGroup |
302 | luser-opts | LuserOpt |
303 | stations_visited | StationVisited |
304 | routeChange | RouteChange |
996be9ee |
305 | |
306 | =head2 inflect_plural |
307 | |
308 | Just like L</moniker_map> above (can be hash/code-ref, falls back to default |
309 | if hash key does not exist or coderef returns false), but acts as a map |
310 | for pluralizing relationship names. The default behavior is to utilize |
311 | L<Lingua::EN::Inflect::Number/to_PL>. |
312 | |
313 | =head2 inflect_singular |
314 | |
315 | As L</inflect_plural> above, but for singularizing relationship names. |
316 | Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>. |
317 | |
9c9c2f2b |
318 | =head2 schema_base_class |
319 | |
320 | Base class for your schema classes. Defaults to 'DBIx::Class::Schema'. |
321 | |
322 | =head2 result_base_class |
323 | |
2229729e |
324 | Base class for your table classes (aka result classes). Defaults to |
325 | 'DBIx::Class::Core'. |
9c9c2f2b |
326 | |
996be9ee |
327 | =head2 additional_base_classes |
328 | |
329 | List of additional base classes all of your table classes will use. |
330 | |
331 | =head2 left_base_classes |
332 | |
333 | List of additional base classes all of your table classes will use |
334 | that need to be leftmost. |
335 | |
336 | =head2 additional_classes |
337 | |
338 | List of additional classes which all of your table classes will use. |
339 | |
340 | =head2 components |
341 | |
342 | List of additional components to be loaded into all of your table |
eccc52fe |
343 | classes. A good example would be |
344 | L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime> |
996be9ee |
345 | |
346 | =head2 resultset_components |
347 | |
8f9d7ce5 |
348 | List of additional ResultSet components to be loaded into your table |
996be9ee |
349 | classes. A good example would be C<AlwaysRS>. Component |
350 | C<ResultSetManager> will be automatically added to the above |
351 | C<components> list if this option is set. |
352 | |
f44ecc2f |
353 | =head2 use_namespaces |
354 | |
f22644d7 |
355 | This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass |
356 | a C<0>. |
357 | |
f44ecc2f |
358 | Generate result class names suitable for |
359 | L<DBIx::Class::Schema/load_namespaces> and call that instead of |
360 | L<DBIx::Class::Schema/load_classes>. When using this option you can also |
361 | specify any of the options for C<load_namespaces> (i.e. C<result_namespace>, |
362 | C<resultset_namespace>, C<default_resultset_class>), and they will be added |
363 | to the call (and the generated result class names adjusted appropriately). |
364 | |
996be9ee |
365 | =head2 dump_directory |
366 | |
367 | This option is designed to be a tool to help you transition from this |
368 | loader to a manually-defined schema when you decide it's time to do so. |
369 | |
370 | The value of this option is a perl libdir pathname. Within |
371 | that directory this module will create a baseline manual |
372 | L<DBIx::Class::Schema> module set, based on what it creates at runtime |
373 | in memory. |
374 | |
375 | The created schema class will have the same classname as the one on |
376 | which you are setting this option (and the ResultSource classes will be |
7cab3ab7 |
377 | based on this name as well). |
996be9ee |
378 | |
8f9d7ce5 |
379 | Normally you wouldn't hard-code this setting in your schema class, as it |
996be9ee |
380 | is meant for one-time manual usage. |
381 | |
382 | See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the |
383 | recommended way to access this functionality. |
384 | |
d65cda9e |
385 | =head2 dump_overwrite |
386 | |
28b4691d |
387 | Deprecated. See L</really_erase_my_files> below, which does *not* mean |
388 | the same thing as the old C<dump_overwrite> setting from previous releases. |
389 | |
390 | =head2 really_erase_my_files |
391 | |
7cab3ab7 |
392 | Default false. If true, Loader will unconditionally delete any existing |
393 | files before creating the new ones from scratch when dumping a schema to disk. |
394 | |
395 | The default behavior is instead to only replace the top portion of the |
396 | file, up to and including the final stanza which contains |
397 | C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!> |
398 | leaving any customizations you placed after that as they were. |
399 | |
28b4691d |
400 | When C<really_erase_my_files> is not set, if the output file already exists, |
7cab3ab7 |
401 | but the aforementioned final stanza is not found, or the checksum |
402 | contained there does not match the generated contents, Loader will |
403 | croak and not touch the file. |
d65cda9e |
404 | |
28b4691d |
405 | You should really be using version control on your schema classes (and all |
406 | of the rest of your code for that matter). Don't blame me if a bug in this |
407 | code wipes something out when it shouldn't have, you've been warned. |
408 | |
639a1367 |
409 | =head2 overwrite_modifications |
410 | |
411 | Default false. If false, when updating existing files, Loader will |
412 | refuse to modify any Loader-generated code that has been modified |
413 | since its last run (as determined by the checksum Loader put in its |
414 | comment lines). |
415 | |
416 | If true, Loader will discard any manual modifications that have been |
417 | made to Loader-generated code. |
418 | |
419 | Again, you should be using version control on your schema classes. Be |
420 | careful with this option. |
421 | |
3a368709 |
422 | =head2 custom_column_info |
423 | |
d67d058e |
424 | Hook for adding extra attributes to the |
425 | L<column_info|DBIx::Class::ResultSource/column_info> for a column. |
426 | |
427 | Must be a coderef that returns a hashref with the extra attributes. |
428 | |
429 | Receives the table name, column name and column_info. |
430 | |
431 | For example: |
432 | |
433 | custom_column_info => sub { |
434 | my ($table_name, $column_name, $column_info) = @_; |
435 | |
436 | if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') { |
437 | return { is_snoopy => 1 }; |
438 | } |
439 | }, |
3a368709 |
440 | |
d67d058e |
441 | This attribute can also be used to set C<inflate_datetime> on a non-datetime |
442 | column so it also receives the L</datetime_timezone> and/or L</datetime_locale>. |
3a368709 |
443 | |
42e785fa |
444 | =head2 datetime_timezone |
445 | |
d67d058e |
446 | Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all |
447 | columns with the DATE/DATETIME/TIMESTAMP data_types. |
42e785fa |
448 | |
449 | =head2 datetime_locale |
450 | |
d67d058e |
451 | Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all |
452 | columns with the DATE/DATETIME/TIMESTAMP data_types. |
42e785fa |

455 | |
456 | File in Perl format, which should return a HASH reference, from which to read |
457 | loader options. |
458 | |
7ffafa37 |
459 | =head2 preserve_case |
bc1cb85e |
460 | |
461 | Usually column names are lowercased, to make them easier to work with in |
462 | L<DBIx::Class>. This option lets you turn this behavior off, if the driver |
463 | supports it. |
464 | |
465 | Drivers for case sensitive databases like Sybase ASE or MSSQL with a |
466 | case-sensitive collation will turn this option on unconditionally. |
467 | |
468 | Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support |
469 | setting this option. |
470 | |
7ffafa37 |
471 | =head2 qualify_objects |
69219349 |
472 | |
473 | Set to true to prepend the L</db_schema> to table names for C<< |
474 | __PACKAGE__->table >> calls, and to some other things like Oracle sequences. |
