81 | =head1 NAME |
82 | |
83 | DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation. |
84 | |
85 | =head1 SYNOPSIS |
86 | |
87 | See L<DBIx::Class::Schema::Loader> |
88 | |
89 | =head1 DESCRIPTION |
90 | |
91 | This is the base class for the storage-specific C<DBIx::Class::Schema::*> |
92 | classes, and implements the common functionality between them. |
93 | |
94 | =head1 CONSTRUCTOR OPTIONS |
95 | |
96 | These constructor options are the base options for |
29ddb54c |
97 | L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are: |
3953cbee |
98 | |
59cfa251 |
99 | =head2 skip_relationships |
996be9ee |
100 | |
59cfa251 |
101 | Skip setting up relationships. The default is to attempt the loading |
102 | of relationships. |
996be9ee |
103 | |
0ca61324 |
104 | =head2 skip_load_external |
105 | |
106 | Skip loading of other classes in @INC. The default is to merge all other classes |
107 | with the same name found in @INC into the schema file we are creating. |
108 | |
9a95164d |
109 | =head2 naming |
110 | |
111 | Static schemas (ones dumped to disk) will, by default, use the new-style 0.05XXX |
112 | relationship names and singularized Results, unless you're overwriting an |
113 | existing dump made by a 0.04XXX version of L<DBIx::Class::Schema::Loader>, in |
114 | which case the backward compatible RelBuilder will be activated, and |
115 | singularization will be turned off. |
116 | |
117 | Specifying |
118 | |
119 | naming => 'v5' |
120 | |
121 | will disable the backward-compatible RelBuilder and use |
122 | the new-style relationship names along with singularized Results, even when |
123 | overwriting a dump made with an earlier version. |
124 | |
125 | The option also takes a hashref: |
126 | |
a8d229ff |
127 | naming => { relationships => 'v5', monikers => 'v4' } |
128 | |
129 | The keys are: |
130 | |
131 | =over 4 |
132 | |
133 | =item relationships |
134 | |
135 | How to name relationship accessors. |
136 | |
137 | =item monikers |
138 | |
139 | How to name Result classes. |
140 | |
141 | =back |
9a95164d |
142 | |
143 | The values can be: |
144 | |
145 | =over 4 |
146 | |
147 | =item current |
148 | |
149 | Latest default style, whatever that happens to be. |
150 | |
151 | =item v5 |
152 | |
153 | Version 0.05XXX style. |
154 | |
155 | =item v4 |
156 | |
157 | Version 0.04XXX style. |
158 | |
159 | =back |
160 | |
161 | Dynamic schemas will always default to the 0.04XXX relationship names and won't |
162 | singularize Results for backward compatibility, to activate the new RelBuilder |
163 | and singularization put this in your C<Schema.pm> file: |
164 | |
165 | __PACKAGE__->naming('current'); |
166 | |
167 | Or if you prefer to use 0.05XXX features but insure that nothing breaks in the |
168 | next major version upgrade: |
169 | |
170 | __PACKAGE__->naming('v5'); |
171 | |
492dce8d |
172 | =head2 generate_pod |
173 | |
174 | By default POD will be generated for columns and relationships, using database |
7f2de014 |
175 | metadata for the text if available and supported. |
176 | |
177 | Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only |
178 | supported for Postgres right now. |
492dce8d |
179 | |
180 | Set this to C<0> to turn off all POD generation. |
181 | |
43b982ea |
182 | =head2 pod_comment_mode |
183 | |
f7976fea |
184 | Controls where table comments appear in the generated POD. Smaller table |
185 | comments are appended to the C<NAME> section of the documentation, and larger |
186 | ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION> |
187 | section to be generated with the comment always, only use C<NAME>, or choose |
188 | the length threshold at which the comment is forced into the description. |
43b982ea |
189 | |
34896b5e |
190 | =over 4 |
191 | |
192 | =item name |
193 | |
194 | Use C<NAME> section only. |
195 | |
196 | =item description |
197 | |
198 | Force C<DESCRIPTION> always. |
199 | |
200 | =item auto |
201 | |
202 | Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the |
203 | default. |
204 | |
205 | =back |
43b982ea |
206 | |
207 | =head2 pod_comment_spillover_length |
208 | |
209 | When pod_comment_mode is set to C<auto>, this is the length of the comment at |
210 | which it will be forced into a separate description section. |
211 | |
212 | The default is C<60> |
213 | |
c8c27020 |
214 | =head2 relationship_attrs |
215 | |
216 | Hashref of attributes to pass to each generated relationship, listed |
217 | by type. Also supports relationship type 'all', containing options to |
218 | pass to all generated relationships. Attributes set for more specific |
219 | relationship types override those set in 'all'. |
220 | |
221 | For example: |
222 | |
223 | relationship_attrs => { |
224 | all => { cascade_delete => 0 }, |
225 | has_many => { cascade_delete => 1 }, |
226 | }, |
227 | |
228 | will set the C<cascade_delete> option to 0 for all generated relationships, |
229 | except for C<has_many>, which will have cascade_delete as 1. |
230 | |
231 | NOTE: this option is not supported if v4 backward-compatible naming is |
232 | set either globally (naming => 'v4') or just for relationships. |
233 | |
996be9ee |
234 | =head2 debug |
235 | |
236 | If set to true, each constructive L<DBIx::Class> statement the loader |
237 | decides to execute will be C<warn>-ed before execution. |
238 | |
d65cda9e |
239 | =head2 db_schema |
240 | |
241 | Set the name of the schema to load (schema in the sense that your database |
242 | vendor means it). Does not currently support loading more than one schema |
243 | name. |
244 | |
996be9ee |
245 | =head2 constraint |
246 | |
247 | Only load tables matching regex. Best specified as a qr// regex. |
248 | |
249 | =head2 exclude |
250 | |
251 | Exclude tables matching regex. Best specified as a qr// regex. |
252 | |
253 | =head2 moniker_map |
254 | |
8f9d7ce5 |
255 | Overrides the default table name to moniker translation. Can be either |
256 | a hashref of table keys and moniker values, or a coderef for a translator |
996be9ee |
257 | function taking a single scalar table name argument and returning |
258 | a scalar moniker. If the hash entry does not exist, or the function |
259 | returns a false value, the code falls back to default behavior |
260 | for that table name. |
261 | |
9cc8e7e1 |
262 | The default behavior is to singularize the table name, and: C<join '', map |
263 | ucfirst, split /[\W_]+/, lc $table>, which is to say: lowercase everything, |
264 | split up the table name into chunks anywhere a non-alpha-numeric character |
265 | occurs, change the case of first letter of each chunk to upper case, and put |
266 | the chunks back together. Examples: |
996be9ee |
267 | |
268 | Table Name | Moniker Name |
269 | --------------------------- |
270 | luser | Luser |
271 | luser_group | LuserGroup |
48b8d687 |
272 | luser-opts | LuserOpt |
996be9ee |
273 | |
274 | =head2 inflect_plural |
275 | |
276 | Just like L</moniker_map> above (can be hash/code-ref, falls back to default |
277 | if hash key does not exist or coderef returns false), but acts as a map |
278 | for pluralizing relationship names. The default behavior is to utilize |
279 | L<Lingua::EN::Inflect::Number/to_PL>. |
280 | |
281 | =head2 inflect_singular |
282 | |
283 | As L</inflect_plural> above, but for singularizing relationship names. |
284 | Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>. |
285 | |
9c9c2f2b |
286 | =head2 schema_base_class |
287 | |
288 | Base class for your schema classes. Defaults to 'DBIx::Class::Schema'. |
289 | |
290 | =head2 result_base_class |
291 | |
2229729e |
292 | Base class for your table classes (aka result classes). Defaults to |
293 | 'DBIx::Class::Core'. |
9c9c2f2b |
294 | |
996be9ee |
295 | =head2 additional_base_classes |
296 | |
297 | List of additional base classes all of your table classes will use. |
298 | |
299 | =head2 left_base_classes |
300 | |
301 | List of additional base classes all of your table classes will use |
302 | that need to be leftmost. |
303 | |
304 | =head2 additional_classes |
305 | |
306 | List of additional classes which all of your table classes will use. |
307 | |
308 | =head2 components |
309 | |
310 | List of additional components to be loaded into all of your table |
311 | classes. A good example would be C<ResultSetManager>. |
312 | |
313 | =head2 resultset_components |
314 | |
8f9d7ce5 |
315 | List of additional ResultSet components to be loaded into your table |
996be9ee |
316 | classes. A good example would be C<AlwaysRS>. Component |
317 | C<ResultSetManager> will be automatically added to the above |
318 | C<components> list if this option is set. |
319 | |
f44ecc2f |
320 | =head2 use_namespaces |
321 | |
f22644d7 |
322 | This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass |
323 | a C<0>. |
324 | |
f44ecc2f |
325 | Generate result class names suitable for |
326 | L<DBIx::Class::Schema/load_namespaces> and call that instead of |
327 | L<DBIx::Class::Schema/load_classes>. When using this option you can also |
328 | specify any of the options for C<load_namespaces> (i.e. C<result_namespace>, |
329 | C<resultset_namespace>, C<default_resultset_class>), and they will be added |
330 | to the call (and the generated result class names adjusted appropriately). |
331 | |
996be9ee |
332 | =head2 dump_directory |
333 | |
334 | This option is designed to be a tool to help you transition from this |
335 | loader to a manually-defined schema when you decide it's time to do so. |
336 | |
337 | The value of this option is a perl libdir pathname. Within |
338 | that directory this module will create a baseline manual |
339 | L<DBIx::Class::Schema> module set, based on what it creates at runtime |
340 | in memory. |
341 | |
342 | The created schema class will have the same classname as the one on |
343 | which you are setting this option (and the ResultSource classes will be |
7cab3ab7 |
344 | based on this name as well). |
996be9ee |
345 | |
8f9d7ce5 |
346 | Normally you wouldn't hard-code this setting in your schema class, as it |
996be9ee |
347 | is meant for one-time manual usage. |
348 | |
349 | See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the |
350 | recommended way to access this functionality. |
351 | |
d65cda9e |
352 | =head2 dump_overwrite |
353 | |
28b4691d |
354 | Deprecated. See L</really_erase_my_files> below, which does *not* mean |
355 | the same thing as the old C<dump_overwrite> setting from previous releases. |
356 | |
357 | =head2 really_erase_my_files |
358 | |
7cab3ab7 |
359 | Default false. If true, Loader will unconditionally delete any existing |
360 | files before creating the new ones from scratch when dumping a schema to disk. |
361 | |
362 | The default behavior is instead to only replace the top portion of the |
363 | file, up to and including the final stanza which contains |
364 | C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!> |
365 | leaving any customizations you placed after that as they were. |
366 | |
28b4691d |
367 | When C<really_erase_my_files> is not set, if the output file already exists, |
7cab3ab7 |
368 | but the aforementioned final stanza is not found, or the checksum |
369 | contained there does not match the generated contents, Loader will |
370 | croak and not touch the file. |
d65cda9e |
371 | |
28b4691d |
372 | You should really be using version control on your schema classes (and all |
373 | of the rest of your code for that matter). Don't blame me if a bug in this |
374 | code wipes something out when it shouldn't have, you've been warned. |
375 | |
639a1367 |
376 | =head2 overwrite_modifications |
377 | |
378 | Default false. If false, when updating existing files, Loader will |
379 | refuse to modify any Loader-generated code that has been modified |
380 | since its last run (as determined by the checksum Loader put in its |
381 | comment lines). |
382 | |
383 | If true, Loader will discard any manual modifications that have been |
384 | made to Loader-generated code. |
385 | |
386 | Again, you should be using version control on your schema classes. Be |
387 | careful with this option. |
388 | |
3a368709 |
389 | =head2 custom_column_info |
390 | |
d67d058e |
391 | Hook for adding extra attributes to the |
392 | L<column_info|DBIx::Class::ResultSource/column_info> for a column. |
393 | |
394 | Must be a coderef that returns a hashref with the extra attributes. |
395 | |
396 | Receives the table name, column name and column_info. |
397 | |
398 | For example: |
399 | |
400 | custom_column_info => sub { |
401 | my ($table_name, $column_name, $column_info) = @_; |
402 | |
403 | if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') { |
404 | return { is_snoopy => 1 }; |
405 | } |
406 | }, |
3a368709 |
407 | |
d67d058e |
408 | This attribute can also be used to set C<inflate_datetime> on a non-datetime |
409 | column so it also receives the L</datetime_timezone> and/or L</datetime_locale>. |
3a368709 |
410 | |
42e785fa |
411 | =head2 datetime_timezone |
412 | |
d67d058e |
413 | Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all |
414 | columns with the DATE/DATETIME/TIMESTAMP data_types. |
42e785fa |
415 | |
416 | =head2 datetime_locale |
417 | |
d67d058e |
418 | Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all |
419 | columns with the DATE/DATETIME/TIMESTAMP data_types. |
42e785fa |
420 | |
996be9ee |
421 | =head1 METHODS |
422 | |
423 | None of these methods are intended for direct invocation by regular |
d67d058e |
424 | users of L<DBIx::Class::Schema::Loader>. Some are proxied via |
425 | L<DBIx::Class::Schema::Loader>. |
