95 | =head1 NAME |
96 | |
97 | DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation. |
98 | |
99 | =head1 SYNOPSIS |
100 | |
101 | See L<DBIx::Class::Schema::Loader> |
102 | |
103 | =head1 DESCRIPTION |
104 | |
105 | This is the base class for the storage-specific C<DBIx::Class::Schema::*> |
106 | classes, and implements the common functionality between them. |
107 | |
108 | =head1 CONSTRUCTOR OPTIONS |
109 | |
110 | These constructor options are the base options for |
29ddb54c |
111 | L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are: |
3953cbee |
112 | |
59cfa251 |
113 | =head2 skip_relationships |
996be9ee |
114 | |
59cfa251 |
115 | Skip setting up relationships. The default is to attempt the loading |
116 | of relationships. |
996be9ee |
117 | |
0ca61324 |
118 | =head2 skip_load_external |
119 | |
120 | Skip loading of other classes in @INC. The default is to merge all other classes |
121 | with the same name found in @INC into the schema file we are creating. |
122 | |
9a95164d |
123 | =head2 naming |
124 | |
ecf930e6 |
125 | Static schemas (ones dumped to disk) will, by default, use the new-style |
9a95164d |
126 | relationship names and singularized Results, unless you're overwriting an |
ecf930e6 |
127 | existing dump made by an older version of L<DBIx::Class::Schema::Loader>, in |
128 | which case the backward compatible RelBuilder will be activated, and the |
129 | appropriate monikerization used. |
9a95164d |
130 | |
131 | Specifying |
132 | |
ecf930e6 |
133 | naming => 'current' |
9a95164d |
134 | |
135 | will disable the backward-compatible RelBuilder and use |
136 | the new-style relationship names along with singularized Results, even when |
137 | overwriting a dump made with an earlier version. |
138 | |
139 | The option also takes a hashref: |
140 | |
2a1ff2ee |
141 | naming => { relationships => 'v7', monikers => 'v7' } |
a8d229ff |
142 | |
143 | The keys are: |
144 | |
145 | =over 4 |

148 | |
149 | How to name relationship accessors. |
150 | |
151 | =item monikers |
152 | |
153 | How to name Result classes. |
154 | |
f3a657ef |
155 | =item column_accessors |
156 | |
157 | How to name column accessors in Result classes. |
158 | |
a8d229ff |
159 | =back |
9a95164d |
160 | |
161 | The values can be: |
162 | |
163 | =over 4 |
164 | |
165 | =item current |
166 | |
ecf930e6 |
167 | Latest style, whatever that happens to be. |
168 | |
169 | =item v4 |
170 | |
171 | Unsingularlized monikers, C<has_many> only relationships with no _id stripping. |
9a95164d |
172 | |
173 | =item v5 |
174 | |
ecf930e6 |
175 | Monikers singularized as whole words, C<might_have> relationships for FKs on |
176 | C<UNIQUE> constraints, C<_id> stripping for belongs_to relationships. |
9a95164d |
177 | |
ecf930e6 |
178 | Some of the C<_id> stripping edge cases in C<0.05003> have been reverted for |
179 | the v5 RelBuilder. |
180 | |
181 | =item v6 |
9a95164d |
182 | |
19b7d71c |
183 | All monikers and relationships are inflected using |
184 | L<Lingua::EN::Inflect::Phrase>, and there is more aggressive C<_id> stripping |
185 | from relationship names. |
ecf930e6 |
186 | |
187 | In general, there is very little difference between v5 and v6 schemas. |
9a95164d |
188 | |
9990e58f |
189 | =item v7 |
190 | |
191 | This mode is identical to C<v6> mode, except that monikerization of CamelCase |
192 | table names is also done correctly. |
193 | |
0c1d5b47 |
194 | CamelCase column names in case-preserving mode will also be handled correctly |
195 | for relationship name inflection. See L</preserve_case>. |
19b7d71c |
196 | |
f3a657ef |
197 | In this mode, CamelCase L</column_accessors> are normalized based on case |
198 | transition instead of just being lowercased, so C<FooId> becomes C<foo_id>. |
199 | |
19b7d71c |
200 | If you don't have any CamelCase table or column names, you can upgrade without |
201 | breaking any of your code. |
9990e58f |
202 | |
9a95164d |
203 | =back |
204 | |
205 | Dynamic schemas will always default to the 0.04XXX relationship names and won't |
206 | singularize Results for backward compatibility, to activate the new RelBuilder |
207 | and singularization put this in your C<Schema.pm> file: |
208 | |
209 | __PACKAGE__->naming('current'); |
210 | |
c9cf9b4d |
211 | Or if you prefer to use 0.07XXX features but insure that nothing breaks in the |
9a95164d |
212 | next major version upgrade: |
213 | |
c9cf9b4d |
214 | __PACKAGE__->naming('v7'); |
9a95164d |
215 | |
492dce8d |
216 | =head2 generate_pod |
217 | |
218 | By default POD will be generated for columns and relationships, using database |
7f2de014 |
219 | metadata for the text if available and supported. |
220 | |
221 | Reading database metadata (e.g. C<COMMENT ON TABLE some_table ...>) is only |
222 | supported for Postgres right now. |
492dce8d |
223 | |
224 | Set this to C<0> to turn off all POD generation. |
225 | |
43b982ea |
226 | =head2 pod_comment_mode |
227 | |
f7976fea |
228 | Controls where table comments appear in the generated POD. Smaller table |
229 | comments are appended to the C<NAME> section of the documentation, and larger |
230 | ones are inserted into C<DESCRIPTION> instead. You can force a C<DESCRIPTION> |
231 | section to be generated with the comment always, only use C<NAME>, or choose |
232 | the length threshold at which the comment is forced into the description. |
43b982ea |
233 | |
34896b5e |
234 | =over 4 |
235 | |
236 | =item name |
237 | |
238 | Use C<NAME> section only. |
239 | |
240 | =item description |
241 | |
242 | Force C<DESCRIPTION> always. |
243 | |
244 | =item auto |
245 | |
246 | Use C<DESCRIPTION> if length > L</pod_comment_spillover_length>, this is the |
247 | default. |
248 | |
249 | =back |
43b982ea |
250 | |
251 | =head2 pod_comment_spillover_length |
252 | |
253 | When pod_comment_mode is set to C<auto>, this is the length of the comment at |
254 | which it will be forced into a separate description section. |
255 | |
256 | The default is C<60> |
257 | |
c8c27020 |
258 | =head2 relationship_attrs |
259 | |
260 | Hashref of attributes to pass to each generated relationship, listed |
261 | by type. Also supports relationship type 'all', containing options to |
262 | pass to all generated relationships. Attributes set for more specific |
263 | relationship types override those set in 'all'. |
264 | |
265 | For example: |
266 | |
267 | relationship_attrs => { |
aa0867ee |
268 | belongs_to => { is_deferrable => 0 }, |
c8c27020 |
269 | }, |
270 | |
aa0867ee |
271 | use this to turn off DEFERRABLE on your foreign key constraints. |
c8c27020 |
272 | |
996be9ee |
273 | =head2 debug |
274 | |
275 | If set to true, each constructive L<DBIx::Class> statement the loader |
276 | decides to execute will be C<warn>-ed before execution. |
277 | |
d65cda9e |
278 | =head2 db_schema |
279 | |
280 | Set the name of the schema to load (schema in the sense that your database |
281 | vendor means it). Does not currently support loading more than one schema |
282 | name. |
283 | |
996be9ee |
284 | =head2 constraint |
285 | |
286 | Only load tables matching regex. Best specified as a qr// regex. |
287 | |
288 | =head2 exclude |
289 | |
290 | Exclude tables matching regex. Best specified as a qr// regex. |
291 | |
292 | =head2 moniker_map |
293 | |
8f9d7ce5 |
294 | Overrides the default table name to moniker translation. Can be either |
295 | a hashref of table keys and moniker values, or a coderef for a translator |
996be9ee |
296 | function taking a single scalar table name argument and returning |
297 | a scalar moniker. If the hash entry does not exist, or the function |
298 | returns a false value, the code falls back to default behavior |
299 | for that table name. |
300 | |
9990e58f |
301 | The default behavior is to split on case transition and non-alphanumeric |
302 | boundaries, singularize the resulting phrase, then join the titlecased words |
303 | together. Examples: |
996be9ee |
304 | |
9990e58f |
305 | Table Name | Moniker Name |
306 | --------------------------------- |
307 | luser | Luser |
308 | luser_group | LuserGroup |
309 | luser-opts | LuserOpt |
310 | stations_visited | StationVisited |
311 | routeChange | RouteChange |
996be9ee |
312 | |
cfc5dce3 |
313 | =head2 column_accessor_map |
314 | |
315 | Same as moniker_map, but for column accessor names. If a coderef is |
316 | passed, the code is called with arguments of |
317 | |
318 | the name of the column in the underlying database, |
319 | default accessor name that DBICSL would ordinarily give this column, |
320 | { |
321 | table_class => name of the DBIC class we are building, |
322 | table_moniker => calculated moniker for this table (after moniker_map if present), |
323 | table_name => name of the database table, |
324 | full_table_name => schema-qualified name of the database table (RDBMS specific), |
325 | schema_class => name of the schema class we are building, |
326 | column_info => hashref of column info (data_type, is_nullable, etc), |
327 | } |
328 | |
996be9ee |
329 | =head2 inflect_plural |
330 | |
331 | Just like L</moniker_map> above (can be hash/code-ref, falls back to default |
332 | if hash key does not exist or coderef returns false), but acts as a map |
333 | for pluralizing relationship names. The default behavior is to utilize |
a7a80921 |
334 | L<Lingua::EN::Inflect::Phrase/to_PL>. |
996be9ee |
335 | |
336 | =head2 inflect_singular |
337 | |
338 | As L</inflect_plural> above, but for singularizing relationship names. |
a7a80921 |
339 | Default behavior is to utilize L<Lingua::EN::Inflect::Phrase/to_S>. |
996be9ee |
340 | |
9c9c2f2b |
341 | =head2 schema_base_class |
342 | |
343 | Base class for your schema classes. Defaults to 'DBIx::Class::Schema'. |
344 | |
345 | =head2 result_base_class |
346 | |
2229729e |
347 | Base class for your table classes (aka result classes). Defaults to |
348 | 'DBIx::Class::Core'. |
9c9c2f2b |
349 | |
996be9ee |
350 | =head2 additional_base_classes |
351 | |
352 | List of additional base classes all of your table classes will use. |
353 | |
354 | =head2 left_base_classes |
355 | |
356 | List of additional base classes all of your table classes will use |
357 | that need to be leftmost. |
358 | |
359 | =head2 additional_classes |
360 | |
361 | List of additional classes which all of your table classes will use. |
362 | |
363 | =head2 components |
364 | |
365 | List of additional components to be loaded into all of your table |
eccc52fe |
366 | classes. A good example would be |
367 | L<InflateColumn::DateTime|DBIx::Class::InflateColumn::DateTime> |
996be9ee |
368 | |
f44ecc2f |
369 | =head2 use_namespaces |
370 | |
f22644d7 |
371 | This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass |
372 | a C<0>. |
373 | |
f44ecc2f |
374 | Generate result class names suitable for |
375 | L<DBIx::Class::Schema/load_namespaces> and call that instead of |
376 | L<DBIx::Class::Schema/load_classes>. When using this option you can also |
377 | specify any of the options for C<load_namespaces> (i.e. C<result_namespace>, |
378 | C<resultset_namespace>, C<default_resultset_class>), and they will be added |
379 | to the call (and the generated result class names adjusted appropriately). |
380 | |
996be9ee |
381 | =head2 dump_directory |
382 | |
996be9ee |
383 | The value of this option is a perl libdir pathname. Within |
384 | that directory this module will create a baseline manual |
1ad8e8c3 |
385 | L<DBIx::Class::Schema> module set, based on what it creates at runtime. |
996be9ee |
386 | |
387 | The created schema class will have the same classname as the one on |
388 | which you are setting this option (and the ResultSource classes will be |
7cab3ab7 |
389 | based on this name as well). |
996be9ee |
390 | |
8f9d7ce5 |
391 | Normally you wouldn't hard-code this setting in your schema class, as it |
996be9ee |
392 | is meant for one-time manual usage. |
393 | |
394 | See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the |
395 | recommended way to access this functionality. |
396 | |
d65cda9e |
397 | =head2 dump_overwrite |
398 | |
28b4691d |
399 | Deprecated. See L</really_erase_my_files> below, which does *not* mean |
400 | the same thing as the old C<dump_overwrite> setting from previous releases. |
401 | |
402 | =head2 really_erase_my_files |
403 | |
7cab3ab7 |
404 | Default false. If true, Loader will unconditionally delete any existing |
405 | files before creating the new ones from scratch when dumping a schema to disk. |
406 | |
407 | The default behavior is instead to only replace the top portion of the |
408 | file, up to and including the final stanza which contains |
1a8fd949 |
409 | C<# DO NOT MODIFY THE FIRST PART OF THIS FILE> |
7cab3ab7 |
410 | leaving any customizations you placed after that as they were. |
411 | |
28b4691d |
412 | When C<really_erase_my_files> is not set, if the output file already exists, |
7cab3ab7 |
413 | but the aforementioned final stanza is not found, or the checksum |
414 | contained there does not match the generated contents, Loader will |
415 | croak and not touch the file. |
d65cda9e |
416 | |
28b4691d |
417 | You should really be using version control on your schema classes (and all |
418 | of the rest of your code for that matter). Don't blame me if a bug in this |
419 | code wipes something out when it shouldn't have, you've been warned. |
420 | |
639a1367 |
421 | =head2 overwrite_modifications |
422 | |
423 | Default false. If false, when updating existing files, Loader will |
424 | refuse to modify any Loader-generated code that has been modified |
425 | since its last run (as determined by the checksum Loader put in its |
426 | comment lines). |
427 | |
428 | If true, Loader will discard any manual modifications that have been |
429 | made to Loader-generated code. |
430 | |
431 | Again, you should be using version control on your schema classes. Be |
432 | careful with this option. |
433 | |
3a368709 |
434 | =head2 custom_column_info |
435 | |
d67d058e |
436 | Hook for adding extra attributes to the |
437 | L<column_info|DBIx::Class::ResultSource/column_info> for a column. |
438 | |
439 | Must be a coderef that returns a hashref with the extra attributes. |
440 | |
441 | Receives the table name, column name and column_info. |
442 | |
443 | For example: |
444 | |
445 | custom_column_info => sub { |
446 | my ($table_name, $column_name, $column_info) = @_; |
447 | |
448 | if ($column_name eq 'dog' && $column_info->{default_value} eq 'snoopy') { |
449 | return { is_snoopy => 1 }; |
450 | } |
451 | }, |
3a368709 |
452 | |
d67d058e |
453 | This attribute can also be used to set C<inflate_datetime> on a non-datetime |
454 | column so it also receives the L</datetime_timezone> and/or L</datetime_locale>. |
3a368709 |
455 | |
42e785fa |
456 | =head2 datetime_timezone |
457 | |
d67d058e |
458 | Sets the timezone attribute for L<DBIx::Class::InflateColumn::DateTime> for all |
459 | columns with the DATE/DATETIME/TIMESTAMP data_types. |
42e785fa |
460 | |
461 | =head2 datetime_locale |
462 | |
d67d058e |
463 | Sets the locale attribute for L<DBIx::Class::InflateColumn::DateTime> for all |
464 | columns with the DATE/DATETIME/TIMESTAMP data_types. |
42e785fa |
465 | |
57a9fc92 |
466 | =head2 datetime_undef_if_invalid |
467 | |
468 | Pass a C<0> for this option when using MySQL if you B<DON'T> want C<< |
469 | datetime_undef_if_invalid => 1 >> in your column info for DATE, DATETIME and |
470 | TIMESTAMP columns. |
471 | |
472 | The default is recommended to deal with data such as C<00/00/00> which |
473 | sometimes ends up in such columns in MySQL. |
474 | |
7ffafa37 |
475 | =head2 config_file |
73099af4 |
476 | |
477 | File in Perl format, which should return a HASH reference, from which to read |
478 | loader options. |
479 | |
7ffafa37 |
480 | =head2 preserve_case |
bc1cb85e |
481 | |
482 | Usually column names are lowercased, to make them easier to work with in |
483 | L<DBIx::Class>. This option lets you turn this behavior off, if the driver |
484 | supports it. |
485 | |
486 | Drivers for case sensitive databases like Sybase ASE or MSSQL with a |
487 | case-sensitive collation will turn this option on unconditionally. |
488 | |
489 | Currently the drivers for SQLite, mysql, MSSQL and Firebird/InterBase support |
490 | setting this option. |
491 | |
7ffafa37 |
492 | =head2 qualify_objects |
69219349 |
493 | |
494 | Set to true to prepend the L</db_schema> to table names for C<< |
495 | __PACKAGE__->table >> calls, and to some other things like Oracle sequences. |
496 | |
7d0ea6b9 |
497 | =head2 use_moose |
498 | |
499 | Creates Schema and Result classes that use L<Moose>, L<MooseX::NonMoose> and |
1336ac63 |
500 | L<namespace::autoclean>. The default content after the md5 sum also makes the |
501 | classes immutable. |
7d0ea6b9 |
502 | |
503 | It is safe to upgrade your existing Schema to this option. |
504 | |
15c4393b |
505 | =head2 col_collision_map |
506 | |
507 | This option controls how accessors for column names which collide with perl |
508 | methods are named. See L</COLUMN ACCESSOR COLLISIONS> for more information. |
509 | |
dcc51168 |
510 | This option takes either a single L<sprintf|perlfunc/sprintf> format or a hashref of |
15c4393b |
511 | strings which are compiled to regular expressions that map to |
dcc51168 |
512 | L<sprintf|perlfunc/sprintf> formats. |
15c4393b |
513 | |
514 | Examples: |
515 | |
516 | col_collision_map => 'column_%s' |
517 | |
518 | col_collision_map => { '(.*)' => 'column_%s' } |
519 | |
520 | col_collision_map => { '(foo).*(bar)' => 'column_%s_%s' } |
521 | |
a7116285 |
522 | =head2 rel_collision_map |
523 | |
524 | Works just like L</col_collision_map>, but for relationship names/accessors |
525 | rather than column names/accessors. |
526 | |
527 | The default is to just append C<_rel> to the relationship name, see |
528 | L</RELATIONSHIP NAME COLLISIONS>. |
529 | |
996be9ee |
530 | =head1 METHODS |
531 | |
532 | None of these methods are intended for direct invocation by regular |
d67d058e |
533 | users of L<DBIx::Class::Schema::Loader>. Some are proxied via |
534 | L<DBIx::Class::Schema::Loader>. |

2082 | Returns a hashref of loaded table to moniker mappings. There will |
996be9ee |
2083 | be two entries for each table, the original name and the "normalized" |
2084 | name, in the case that the two are different (such as databases |
2085 | that like uppercase table names, or preserve your original mixed-case |
2086 | definitions, or what-have-you). |

2089 | |
8f9d7ce5 |
2090 | Returns a hashref of table to class mappings. In some cases it will |
996be9ee |
2091 | contain multiple entries per table for the original and normalized table |
2092 | names, as above in L</monikers>. |

2094 | =head1 COLUMN ACCESSOR COLLISIONS |
2095 | |
2096 | Occasionally you may have a column name that collides with a perl method, such |
2097 | as C<can>. In such cases, the default action is to set the C<accessor> of the |
2098 | column spec to C<undef>. |
2099 | |
2100 | You can then name the accessor yourself by placing code such as the following |
2101 | below the md5: |
2102 | |
2103 | __PACKAGE__->add_column('+can' => { accessor => 'my_can' }); |
2104 | |
2105 | Another option is to use the L</col_collision_map> option. |
2106 | |

2107 | =head1 RELATIONSHIP NAME COLLISIONS |
2108 | |
2109 | In very rare cases, you may get a collision between a generated relationship |
2110 | name and a method in your Result class, for example if you have a foreign key |
2111 | called C<belongs_to>. |
2112 | |
2113 | This is a problem because relationship names are also relationship accessor |
2114 | methods in L<DBIx::Class>. |
2115 | |
2116 | The default behavior is to append C<_rel> to the relationship name and print |
2117 | out a warning that refers to this text. |
2118 | |
2119 | You can also control the renaming with the L</rel_collision_map> option. |
