70 | =head1 NAME |
71 | |
72 | DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation. |
73 | |
74 | =head1 SYNOPSIS |
75 | |
76 | See L<DBIx::Class::Schema::Loader> |
77 | |
78 | =head1 DESCRIPTION |
79 | |
80 | This is the base class for the storage-specific C<DBIx::Class::Schema::*> |
81 | classes, and implements the common functionality between them. |
82 | |
83 | =head1 CONSTRUCTOR OPTIONS |
84 | |
85 | These constructor options are the base options for |
29ddb54c |
86 | L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are: |
3953cbee |
87 | |
59cfa251 |
88 | =head2 skip_relationships |
996be9ee |
89 | |
59cfa251 |
90 | Skip setting up relationships. The default is to attempt the loading |
91 | of relationships. |
996be9ee |
92 | |
0ca61324 |
93 | =head2 skip_load_external |
94 | |
95 | Skip loading of other classes in @INC. The default is to merge all other classes |
96 | with the same name found in @INC into the schema file we are creating. |
97 | |
9a95164d |
98 | =head2 naming |
99 | |
100 | Static schemas (ones dumped to disk) will, by default, use the new-style 0.05XXX |
101 | relationship names and singularized Results, unless you're overwriting an |
102 | existing dump made by a 0.04XXX version of L<DBIx::Class::Schema::Loader>, in |
103 | which case the backward compatible RelBuilder will be activated, and |
104 | singularization will be turned off. |
105 | |
106 | Specifying |
107 | |
108 | naming => 'v5' |
109 | |
110 | will disable the backward-compatible RelBuilder and use |
111 | the new-style relationship names along with singularized Results, even when |
112 | overwriting a dump made with an earlier version. |
113 | |
114 | The option also takes a hashref: |
115 | |
a8d229ff |
116 | naming => { relationships => 'v5', monikers => 'v4' } |
117 | |
118 | The keys are: |
119 | |
120 | =over 4 |
121 | |
122 | =item relationships |
123 | |
124 | How to name relationship accessors. |
125 | |
126 | =item monikers |
127 | |
128 | How to name Result classes. |
129 | |
130 | =back |
9a95164d |
131 | |
132 | The values can be: |
133 | |
134 | =over 4 |
135 | |
136 | =item current |
137 | |
138 | Latest default style, whatever that happens to be. |
139 | |
140 | =item v5 |
141 | |
142 | Version 0.05XXX style. |
143 | |
144 | =item v4 |
145 | |
146 | Version 0.04XXX style. |
147 | |
148 | =back |
149 | |
150 | Dynamic schemas will always default to the 0.04XXX relationship names and won't |
151 | singularize Results for backward compatibility, to activate the new RelBuilder |
152 | and singularization put this in your C<Schema.pm> file: |
153 | |
154 | __PACKAGE__->naming('current'); |
155 | |
156 | Or if you prefer to use 0.05XXX features but insure that nothing breaks in the |
157 | next major version upgrade: |
158 | |
159 | __PACKAGE__->naming('v5'); |
160 | |
c8c27020 |
161 | =head2 relationship_attrs |
162 | |
163 | Hashref of attributes to pass to each generated relationship, listed |
164 | by type. Also supports relationship type 'all', containing options to |
165 | pass to all generated relationships. Attributes set for more specific |
166 | relationship types override those set in 'all'. |
167 | |
168 | For example: |
169 | |
170 | relationship_attrs => { |
171 | all => { cascade_delete => 0 }, |
172 | has_many => { cascade_delete => 1 }, |
173 | }, |
174 | |
175 | will set the C<cascade_delete> option to 0 for all generated relationships, |
176 | except for C<has_many>, which will have cascade_delete as 1. |
177 | |
178 | NOTE: this option is not supported if v4 backward-compatible naming is |
179 | set either globally (naming => 'v4') or just for relationships. |
180 | |
996be9ee |
181 | =head2 debug |
182 | |
183 | If set to true, each constructive L<DBIx::Class> statement the loader |
184 | decides to execute will be C<warn>-ed before execution. |
185 | |
d65cda9e |
186 | =head2 db_schema |
187 | |
188 | Set the name of the schema to load (schema in the sense that your database |
189 | vendor means it). Does not currently support loading more than one schema |
190 | name. |
191 | |
996be9ee |
192 | =head2 constraint |
193 | |
194 | Only load tables matching regex. Best specified as a qr// regex. |
195 | |
196 | =head2 exclude |
197 | |
198 | Exclude tables matching regex. Best specified as a qr// regex. |
199 | |
200 | =head2 moniker_map |
201 | |
8f9d7ce5 |
202 | Overrides the default table name to moniker translation. Can be either |
203 | a hashref of table keys and moniker values, or a coderef for a translator |
996be9ee |
204 | function taking a single scalar table name argument and returning |
205 | a scalar moniker. If the hash entry does not exist, or the function |
206 | returns a false value, the code falls back to default behavior |
207 | for that table name. |
208 | |
9cc8e7e1 |
209 | The default behavior is to singularize the table name, and: C<join '', map |
210 | ucfirst, split /[\W_]+/, lc $table>, which is to say: lowercase everything, |
211 | split up the table name into chunks anywhere a non-alpha-numeric character |
212 | occurs, change the case of first letter of each chunk to upper case, and put |
213 | the chunks back together. Examples: |
996be9ee |
214 | |
215 | Table Name | Moniker Name |
216 | --------------------------- |
217 | luser | Luser |
218 | luser_group | LuserGroup |
48b8d687 |
219 | luser-opts | LuserOpt |
996be9ee |
220 | |
221 | =head2 inflect_plural |
222 | |
223 | Just like L</moniker_map> above (can be hash/code-ref, falls back to default |
224 | if hash key does not exist or coderef returns false), but acts as a map |
225 | for pluralizing relationship names. The default behavior is to utilize |
226 | L<Lingua::EN::Inflect::Number/to_PL>. |
227 | |
228 | =head2 inflect_singular |
229 | |
230 | As L</inflect_plural> above, but for singularizing relationship names. |
231 | Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>. |
232 | |
9c9c2f2b |
233 | =head2 schema_base_class |
234 | |
235 | Base class for your schema classes. Defaults to 'DBIx::Class::Schema'. |
236 | |
237 | =head2 result_base_class |
238 | |
2229729e |
239 | Base class for your table classes (aka result classes). Defaults to |
240 | 'DBIx::Class::Core'. |
9c9c2f2b |
241 | |
996be9ee |
242 | =head2 additional_base_classes |
243 | |
244 | List of additional base classes all of your table classes will use. |
245 | |
246 | =head2 left_base_classes |
247 | |
248 | List of additional base classes all of your table classes will use |
249 | that need to be leftmost. |
250 | |
251 | =head2 additional_classes |
252 | |
253 | List of additional classes which all of your table classes will use. |
254 | |
255 | =head2 components |
256 | |
257 | List of additional components to be loaded into all of your table |
258 | classes. A good example would be C<ResultSetManager>. |
259 | |
260 | =head2 resultset_components |
261 | |
8f9d7ce5 |
262 | List of additional ResultSet components to be loaded into your table |
996be9ee |
263 | classes. A good example would be C<AlwaysRS>. Component |
264 | C<ResultSetManager> will be automatically added to the above |
265 | C<components> list if this option is set. |
266 | |
f44ecc2f |
267 | =head2 use_namespaces |
268 | |
f22644d7 |
269 | This is now the default, to go back to L<DBIx::Class::Schema/load_classes> pass |
270 | a C<0>. |
271 | |
f44ecc2f |
272 | Generate result class names suitable for |
273 | L<DBIx::Class::Schema/load_namespaces> and call that instead of |
274 | L<DBIx::Class::Schema/load_classes>. When using this option you can also |
275 | specify any of the options for C<load_namespaces> (i.e. C<result_namespace>, |
276 | C<resultset_namespace>, C<default_resultset_class>), and they will be added |
277 | to the call (and the generated result class names adjusted appropriately). |
278 | |
996be9ee |
279 | =head2 dump_directory |
280 | |
281 | This option is designed to be a tool to help you transition from this |
282 | loader to a manually-defined schema when you decide it's time to do so. |
283 | |
284 | The value of this option is a perl libdir pathname. Within |
285 | that directory this module will create a baseline manual |
286 | L<DBIx::Class::Schema> module set, based on what it creates at runtime |
287 | in memory. |
288 | |
289 | The created schema class will have the same classname as the one on |
290 | which you are setting this option (and the ResultSource classes will be |
7cab3ab7 |
291 | based on this name as well). |
996be9ee |
292 | |
8f9d7ce5 |
293 | Normally you wouldn't hard-code this setting in your schema class, as it |
996be9ee |
294 | is meant for one-time manual usage. |
295 | |
296 | See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the |
297 | recommended way to access this functionality. |
298 | |
d65cda9e |
299 | =head2 dump_overwrite |
300 | |
28b4691d |
301 | Deprecated. See L</really_erase_my_files> below, which does *not* mean |
302 | the same thing as the old C<dump_overwrite> setting from previous releases. |
303 | |
304 | =head2 really_erase_my_files |
305 | |
7cab3ab7 |
306 | Default false. If true, Loader will unconditionally delete any existing |
307 | files before creating the new ones from scratch when dumping a schema to disk. |
308 | |
309 | The default behavior is instead to only replace the top portion of the |
310 | file, up to and including the final stanza which contains |
311 | C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!> |
312 | leaving any customizations you placed after that as they were. |
313 | |
28b4691d |
314 | When C<really_erase_my_files> is not set, if the output file already exists, |
7cab3ab7 |
315 | but the aforementioned final stanza is not found, or the checksum |
316 | contained there does not match the generated contents, Loader will |
317 | croak and not touch the file. |
d65cda9e |
318 | |
28b4691d |
319 | You should really be using version control on your schema classes (and all |
320 | of the rest of your code for that matter). Don't blame me if a bug in this |
321 | code wipes something out when it shouldn't have, you've been warned. |
322 | |
639a1367 |
323 | =head2 overwrite_modifications |
324 | |
325 | Default false. If false, when updating existing files, Loader will |
326 | refuse to modify any Loader-generated code that has been modified |
327 | since its last run (as determined by the checksum Loader put in its |
328 | comment lines). |
329 | |
330 | If true, Loader will discard any manual modifications that have been |
331 | made to Loader-generated code. |
332 | |
333 | Again, you should be using version control on your schema classes. Be |
334 | careful with this option. |
335 | |
996be9ee |
336 | =head1 METHODS |
337 | |
338 | None of these methods are intended for direct invocation by regular |
339 | users of L<DBIx::Class::Schema::Loader>. Anything you can find here |
340 | can also be found via standard L<DBIx::Class::Schema> methods somehow. |
