67 | =head1 NAME |
68 | |
69 | DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation. |
70 | |
71 | =head1 SYNOPSIS |
72 | |
73 | See L<DBIx::Class::Schema::Loader> |
74 | |
75 | =head1 DESCRIPTION |
76 | |
77 | This is the base class for the storage-specific C<DBIx::Class::Schema::*> |
78 | classes, and implements the common functionality between them. |
79 | |
80 | =head1 CONSTRUCTOR OPTIONS |
81 | |
82 | These constructor options are the base options for |
29ddb54c |
83 | L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are: |
3953cbee |
84 | |
59cfa251 |
85 | =head2 skip_relationships |
996be9ee |
86 | |
59cfa251 |
87 | Skip setting up relationships. The default is to attempt the loading |
88 | of relationships. |
996be9ee |
89 | |
0ca61324 |
90 | =head2 skip_load_external |
91 | |
92 | Skip loading of other classes in @INC. The default is to merge all other classes |
93 | with the same name found in @INC into the schema file we are creating. |
94 | |
9a95164d |
95 | =head2 naming |
96 | |
97 | Static schemas (ones dumped to disk) will, by default, use the new-style 0.05XXX |
98 | relationship names and singularized Results, unless you're overwriting an |
99 | existing dump made by a 0.04XXX version of L<DBIx::Class::Schema::Loader>, in |
100 | which case the backward compatible RelBuilder will be activated, and |
101 | singularization will be turned off. |
102 | |
103 | Specifying |
104 | |
105 | naming => 'v5' |
106 | |
107 | will disable the backward-compatible RelBuilder and use |
108 | the new-style relationship names along with singularized Results, even when |
109 | overwriting a dump made with an earlier version. |
110 | |
111 | The option also takes a hashref: |
112 | |
a8d229ff |
113 | naming => { relationships => 'v5', monikers => 'v4' } |
114 | |
115 | The keys are: |
116 | |
117 | =over 4 |
118 | |
119 | =item relationships |
120 | |
121 | How to name relationship accessors. |
122 | |
123 | =item monikers |
124 | |
125 | How to name Result classes. |
126 | |
127 | =back |
9a95164d |
128 | |
129 | The values can be: |
130 | |
131 | =over 4 |
132 | |
133 | =item current |
134 | |
135 | Latest default style, whatever that happens to be. |
136 | |
137 | =item v5 |
138 | |
139 | Version 0.05XXX style. |
140 | |
141 | =item v4 |
142 | |
143 | Version 0.04XXX style. |
144 | |
145 | =back |
146 | |
147 | Dynamic schemas will always default to the 0.04XXX relationship names and won't |
148 | singularize Results for backward compatibility, to activate the new RelBuilder |
149 | and singularization put this in your C<Schema.pm> file: |
150 | |
151 | __PACKAGE__->naming('current'); |
152 | |
153 | Or if you prefer to use 0.05XXX features but insure that nothing breaks in the |
154 | next major version upgrade: |
155 | |
156 | __PACKAGE__->naming('v5'); |
157 | |
c8c27020 |
158 | =head2 relationship_attrs |
159 | |
160 | Hashref of attributes to pass to each generated relationship, listed |
161 | by type. Also supports relationship type 'all', containing options to |
162 | pass to all generated relationships. Attributes set for more specific |
163 | relationship types override those set in 'all'. |
164 | |
165 | For example: |
166 | |
167 | relationship_attrs => { |
168 | all => { cascade_delete => 0 }, |
169 | has_many => { cascade_delete => 1 }, |
170 | }, |
171 | |
172 | will set the C<cascade_delete> option to 0 for all generated relationships, |
173 | except for C<has_many>, which will have cascade_delete as 1. |
174 | |
175 | NOTE: this option is not supported if v4 backward-compatible naming is |
176 | set either globally (naming => 'v4') or just for relationships. |
177 | |
996be9ee |
178 | =head2 debug |
179 | |
180 | If set to true, each constructive L<DBIx::Class> statement the loader |
181 | decides to execute will be C<warn>-ed before execution. |
182 | |
d65cda9e |
183 | =head2 db_schema |
184 | |
185 | Set the name of the schema to load (schema in the sense that your database |
186 | vendor means it). Does not currently support loading more than one schema |
187 | name. |
188 | |
996be9ee |
189 | =head2 constraint |
190 | |
191 | Only load tables matching regex. Best specified as a qr// regex. |
192 | |
193 | =head2 exclude |
194 | |
195 | Exclude tables matching regex. Best specified as a qr// regex. |
196 | |
197 | =head2 moniker_map |
198 | |
8f9d7ce5 |
199 | Overrides the default table name to moniker translation. Can be either |
200 | a hashref of table keys and moniker values, or a coderef for a translator |
996be9ee |
201 | function taking a single scalar table name argument and returning |
202 | a scalar moniker. If the hash entry does not exist, or the function |
203 | returns a false value, the code falls back to default behavior |
204 | for that table name. |
205 | |
9cc8e7e1 |
206 | The default behavior is to singularize the table name, and: C<join '', map |
207 | ucfirst, split /[\W_]+/, lc $table>, which is to say: lowercase everything, |
208 | split up the table name into chunks anywhere a non-alpha-numeric character |
209 | occurs, change the case of first letter of each chunk to upper case, and put |
210 | the chunks back together. Examples: |
996be9ee |
211 | |
212 | Table Name | Moniker Name |
213 | --------------------------- |
214 | luser | Luser |
215 | luser_group | LuserGroup |
216 | luser-opts | LuserOpts |
217 | |
218 | =head2 inflect_plural |
219 | |
220 | Just like L</moniker_map> above (can be hash/code-ref, falls back to default |
221 | if hash key does not exist or coderef returns false), but acts as a map |
222 | for pluralizing relationship names. The default behavior is to utilize |
223 | L<Lingua::EN::Inflect::Number/to_PL>. |
224 | |
225 | =head2 inflect_singular |
226 | |
227 | As L</inflect_plural> above, but for singularizing relationship names. |
228 | Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>. |
229 | |
9c9c2f2b |
230 | =head2 schema_base_class |
231 | |
232 | Base class for your schema classes. Defaults to 'DBIx::Class::Schema'. |
233 | |
234 | =head2 result_base_class |
235 | |
2229729e |
236 | Base class for your table classes (aka result classes). Defaults to |
237 | 'DBIx::Class::Core'. |
9c9c2f2b |
238 | |
996be9ee |
239 | =head2 additional_base_classes |
240 | |
241 | List of additional base classes all of your table classes will use. |
242 | |
243 | =head2 left_base_classes |
244 | |
245 | List of additional base classes all of your table classes will use |
246 | that need to be leftmost. |
247 | |
248 | =head2 additional_classes |
249 | |
250 | List of additional classes which all of your table classes will use. |
251 | |
252 | =head2 components |
253 | |
254 | List of additional components to be loaded into all of your table |
255 | classes. A good example would be C<ResultSetManager>. |
256 | |
257 | =head2 resultset_components |
258 | |
8f9d7ce5 |
259 | List of additional ResultSet components to be loaded into your table |
996be9ee |
260 | classes. A good example would be C<AlwaysRS>. Component |
261 | C<ResultSetManager> will be automatically added to the above |
262 | C<components> list if this option is set. |
263 | |
f44ecc2f |
264 | =head2 use_namespaces |
265 | |
266 | Generate result class names suitable for |
267 | L<DBIx::Class::Schema/load_namespaces> and call that instead of |
268 | L<DBIx::Class::Schema/load_classes>. When using this option you can also |
269 | specify any of the options for C<load_namespaces> (i.e. C<result_namespace>, |
270 | C<resultset_namespace>, C<default_resultset_class>), and they will be added |
271 | to the call (and the generated result class names adjusted appropriately). |
272 | |
996be9ee |
273 | =head2 dump_directory |
274 | |
275 | This option is designed to be a tool to help you transition from this |
276 | loader to a manually-defined schema when you decide it's time to do so. |
277 | |
278 | The value of this option is a perl libdir pathname. Within |
279 | that directory this module will create a baseline manual |
280 | L<DBIx::Class::Schema> module set, based on what it creates at runtime |
281 | in memory. |
282 | |
283 | The created schema class will have the same classname as the one on |
284 | which you are setting this option (and the ResultSource classes will be |
7cab3ab7 |
285 | based on this name as well). |
996be9ee |
286 | |
8f9d7ce5 |
287 | Normally you wouldn't hard-code this setting in your schema class, as it |
996be9ee |
288 | is meant for one-time manual usage. |
289 | |
290 | See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the |
291 | recommended way to access this functionality. |
292 | |
d65cda9e |
293 | =head2 dump_overwrite |
294 | |
28b4691d |
295 | Deprecated. See L</really_erase_my_files> below, which does *not* mean |
296 | the same thing as the old C<dump_overwrite> setting from previous releases. |
297 | |
298 | =head2 really_erase_my_files |
299 | |
7cab3ab7 |
300 | Default false. If true, Loader will unconditionally delete any existing |
301 | files before creating the new ones from scratch when dumping a schema to disk. |
302 | |
303 | The default behavior is instead to only replace the top portion of the |
304 | file, up to and including the final stanza which contains |
305 | C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!> |
306 | leaving any customizations you placed after that as they were. |
307 | |
28b4691d |
308 | When C<really_erase_my_files> is not set, if the output file already exists, |
7cab3ab7 |
309 | but the aforementioned final stanza is not found, or the checksum |
310 | contained there does not match the generated contents, Loader will |
311 | croak and not touch the file. |
d65cda9e |
312 | |
28b4691d |
313 | You should really be using version control on your schema classes (and all |
314 | of the rest of your code for that matter). Don't blame me if a bug in this |
315 | code wipes something out when it shouldn't have, you've been warned. |
316 | |
639a1367 |
317 | =head2 overwrite_modifications |
318 | |
319 | Default false. If false, when updating existing files, Loader will |
320 | refuse to modify any Loader-generated code that has been modified |
321 | since its last run (as determined by the checksum Loader put in its |
322 | comment lines). |
323 | |
324 | If true, Loader will discard any manual modifications that have been |
325 | made to Loader-generated code. |
326 | |
327 | Again, you should be using version control on your schema classes. Be |
328 | careful with this option. |
329 | |
996be9ee |
330 | =head1 METHODS |
331 | |
332 | None of these methods are intended for direct invocation by regular |
333 | users of L<DBIx::Class::Schema::Loader>. Anything you can find here |
334 | can also be found via standard L<DBIx::Class::Schema> methods somehow. |

1350 | be two entries for each table, the original name and the "normalized" |
1351 | name, in the case that the two are different (such as databases |
1352 | that like uppercase table names, or preserve your original mixed-case |
