62 | =head1 NAME |
63 | |
64 | DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation. |
65 | |
66 | =head1 SYNOPSIS |
67 | |
68 | See L<DBIx::Class::Schema::Loader> |
69 | |
70 | =head1 DESCRIPTION |
71 | |
72 | This is the base class for the storage-specific C<DBIx::Class::Schema::*> |
73 | classes, and implements the common functionality between them. |
74 | |
75 | =head1 CONSTRUCTOR OPTIONS |
76 | |
77 | These constructor options are the base options for |
29ddb54c |
78 | L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are: |
3953cbee |
79 | |
59cfa251 |
80 | =head2 skip_relationships |
996be9ee |
81 | |
59cfa251 |
82 | Skip setting up relationships. The default is to attempt the loading |
83 | of relationships. |
996be9ee |
84 | |
9a95164d |
85 | =head2 naming |
86 | |
87 | Static schemas (ones dumped to disk) will, by default, use the new-style 0.05XXX |
88 | relationship names and singularized Results, unless you're overwriting an |
89 | existing dump made by a 0.04XXX version of L<DBIx::Class::Schema::Loader>, in |
90 | which case the backward compatible RelBuilder will be activated, and |
91 | singularization will be turned off. |
92 | |
93 | Specifying |
94 | |
95 | naming => 'v5' |
96 | |
97 | will disable the backward-compatible RelBuilder and use |
98 | the new-style relationship names along with singularized Results, even when |
99 | overwriting a dump made with an earlier version. |
100 | |
101 | The option also takes a hashref: |
102 | |
a8d229ff |
103 | naming => { relationships => 'v5', monikers => 'v4' } |
104 | |
105 | The keys are: |
106 | |
107 | =over 4 |
108 | |
109 | =item relationships |
110 | |
111 | How to name relationship accessors. |
112 | |
113 | =item monikers |
114 | |
115 | How to name Result classes. |
116 | |
117 | =back |
9a95164d |
118 | |
119 | The values can be: |
120 | |
121 | =over 4 |
122 | |
123 | =item current |
124 | |
125 | Latest default style, whatever that happens to be. |
126 | |
127 | =item v5 |
128 | |
129 | Version 0.05XXX style. |
130 | |
131 | =item v4 |
132 | |
133 | Version 0.04XXX style. |
134 | |
135 | =back |
136 | |
137 | Dynamic schemas will always default to the 0.04XXX relationship names and won't |
138 | singularize Results for backward compatibility, to activate the new RelBuilder |
139 | and singularization put this in your C<Schema.pm> file: |
140 | |
141 | __PACKAGE__->naming('current'); |
142 | |
143 | Or if you prefer to use 0.05XXX features but insure that nothing breaks in the |
144 | next major version upgrade: |
145 | |
146 | __PACKAGE__->naming('v5'); |
147 | |
996be9ee |
148 | =head2 debug |
149 | |
150 | If set to true, each constructive L<DBIx::Class> statement the loader |
151 | decides to execute will be C<warn>-ed before execution. |
152 | |
d65cda9e |
153 | =head2 db_schema |
154 | |
155 | Set the name of the schema to load (schema in the sense that your database |
156 | vendor means it). Does not currently support loading more than one schema |
157 | name. |
158 | |
996be9ee |
159 | =head2 constraint |
160 | |
161 | Only load tables matching regex. Best specified as a qr// regex. |
162 | |
163 | =head2 exclude |
164 | |
165 | Exclude tables matching regex. Best specified as a qr// regex. |
166 | |
167 | =head2 moniker_map |
168 | |
8f9d7ce5 |
169 | Overrides the default table name to moniker translation. Can be either |
170 | a hashref of table keys and moniker values, or a coderef for a translator |
996be9ee |
171 | function taking a single scalar table name argument and returning |
172 | a scalar moniker. If the hash entry does not exist, or the function |
173 | returns a false value, the code falls back to default behavior |
174 | for that table name. |
175 | |
9cc8e7e1 |
176 | The default behavior is to singularize the table name, and: C<join '', map |
177 | ucfirst, split /[\W_]+/, lc $table>, which is to say: lowercase everything, |
178 | split up the table name into chunks anywhere a non-alpha-numeric character |
179 | occurs, change the case of first letter of each chunk to upper case, and put |
180 | the chunks back together. Examples: |
996be9ee |
181 | |
182 | Table Name | Moniker Name |
183 | --------------------------- |
184 | luser | Luser |
185 | luser_group | LuserGroup |
186 | luser-opts | LuserOpts |
187 | |
188 | =head2 inflect_plural |
189 | |
190 | Just like L</moniker_map> above (can be hash/code-ref, falls back to default |
191 | if hash key does not exist or coderef returns false), but acts as a map |
192 | for pluralizing relationship names. The default behavior is to utilize |
193 | L<Lingua::EN::Inflect::Number/to_PL>. |
194 | |
195 | =head2 inflect_singular |
196 | |
197 | As L</inflect_plural> above, but for singularizing relationship names. |
198 | Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>. |
199 | |
9c9c2f2b |
200 | =head2 schema_base_class |
201 | |
202 | Base class for your schema classes. Defaults to 'DBIx::Class::Schema'. |
203 | |
204 | =head2 result_base_class |
205 | |
2229729e |
206 | Base class for your table classes (aka result classes). Defaults to |
207 | 'DBIx::Class::Core'. |
9c9c2f2b |
208 | |
996be9ee |
209 | =head2 additional_base_classes |
210 | |
211 | List of additional base classes all of your table classes will use. |
212 | |
213 | =head2 left_base_classes |
214 | |
215 | List of additional base classes all of your table classes will use |
216 | that need to be leftmost. |
217 | |
218 | =head2 additional_classes |
219 | |
220 | List of additional classes which all of your table classes will use. |
221 | |
222 | =head2 components |
223 | |
224 | List of additional components to be loaded into all of your table |
225 | classes. A good example would be C<ResultSetManager>. |
226 | |
227 | =head2 resultset_components |
228 | |
8f9d7ce5 |
229 | List of additional ResultSet components to be loaded into your table |
996be9ee |
230 | classes. A good example would be C<AlwaysRS>. Component |
231 | C<ResultSetManager> will be automatically added to the above |
232 | C<components> list if this option is set. |
233 | |
f44ecc2f |
234 | =head2 use_namespaces |
235 | |
236 | Generate result class names suitable for |
237 | L<DBIx::Class::Schema/load_namespaces> and call that instead of |
238 | L<DBIx::Class::Schema/load_classes>. When using this option you can also |
239 | specify any of the options for C<load_namespaces> (i.e. C<result_namespace>, |
240 | C<resultset_namespace>, C<default_resultset_class>), and they will be added |
241 | to the call (and the generated result class names adjusted appropriately). |
242 | |
996be9ee |
243 | =head2 dump_directory |
244 | |
245 | This option is designed to be a tool to help you transition from this |
246 | loader to a manually-defined schema when you decide it's time to do so. |
247 | |
248 | The value of this option is a perl libdir pathname. Within |
249 | that directory this module will create a baseline manual |
250 | L<DBIx::Class::Schema> module set, based on what it creates at runtime |
251 | in memory. |
252 | |
253 | The created schema class will have the same classname as the one on |
254 | which you are setting this option (and the ResultSource classes will be |
7cab3ab7 |
255 | based on this name as well). |
996be9ee |
256 | |
8f9d7ce5 |
257 | Normally you wouldn't hard-code this setting in your schema class, as it |
996be9ee |
258 | is meant for one-time manual usage. |
259 | |
260 | See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the |
261 | recommended way to access this functionality. |
262 | |
d65cda9e |
263 | =head2 dump_overwrite |
264 | |
28b4691d |
265 | Deprecated. See L</really_erase_my_files> below, which does *not* mean |
266 | the same thing as the old C<dump_overwrite> setting from previous releases. |
267 | |
268 | =head2 really_erase_my_files |
269 | |
7cab3ab7 |
270 | Default false. If true, Loader will unconditionally delete any existing |
271 | files before creating the new ones from scratch when dumping a schema to disk. |
272 | |
273 | The default behavior is instead to only replace the top portion of the |
274 | file, up to and including the final stanza which contains |
275 | C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!> |
276 | leaving any customizations you placed after that as they were. |
277 | |
28b4691d |
278 | When C<really_erase_my_files> is not set, if the output file already exists, |
7cab3ab7 |
279 | but the aforementioned final stanza is not found, or the checksum |
280 | contained there does not match the generated contents, Loader will |
281 | croak and not touch the file. |
d65cda9e |
282 | |
28b4691d |
283 | You should really be using version control on your schema classes (and all |
284 | of the rest of your code for that matter). Don't blame me if a bug in this |
285 | code wipes something out when it shouldn't have, you've been warned. |
286 | |
996be9ee |
287 | =head1 METHODS |
288 | |
289 | None of these methods are intended for direct invocation by regular |
290 | users of L<DBIx::Class::Schema::Loader>. Anything you can find here |
291 | can also be found via standard L<DBIx::Class::Schema> methods somehow. |
