61 | =head1 NAME |
62 | |
63 | DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation. |
64 | |
65 | =head1 SYNOPSIS |
66 | |
67 | See L<DBIx::Class::Schema::Loader> |
68 | |
69 | =head1 DESCRIPTION |
70 | |
71 | This is the base class for the storage-specific C<DBIx::Class::Schema::*> |
72 | classes, and implements the common functionality between them. |
73 | |
74 | =head1 CONSTRUCTOR OPTIONS |
75 | |
76 | These constructor options are the base options for |
29ddb54c |
77 | L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are: |
3953cbee |
78 | |
59cfa251 |
79 | =head2 skip_relationships |
996be9ee |
80 | |
59cfa251 |
81 | Skip setting up relationships. The default is to attempt the loading |
82 | of relationships. |
996be9ee |
83 | |
9a95164d |
84 | =head2 naming |
85 | |
86 | Static schemas (ones dumped to disk) will, by default, use the new-style 0.05XXX |
87 | relationship names and singularized Results, unless you're overwriting an |
88 | existing dump made by a 0.04XXX version of L<DBIx::Class::Schema::Loader>, in |
89 | which case the backward compatible RelBuilder will be activated, and |
90 | singularization will be turned off. |
91 | |
92 | Specifying |
93 | |
94 | naming => 'v5' |
95 | |
96 | will disable the backward-compatible RelBuilder and use |
97 | the new-style relationship names along with singularized Results, even when |
98 | overwriting a dump made with an earlier version. |
99 | |
100 | The option also takes a hashref: |
101 | |
a8d229ff |
102 | naming => { relationships => 'v5', monikers => 'v4' } |
103 | |
104 | The keys are: |
105 | |
106 | =over 4 |
107 | |
108 | =item relationships |
109 | |
110 | How to name relationship accessors. |
111 | |
112 | =item monikers |
113 | |
114 | How to name Result classes. |
115 | |
116 | =back |
9a95164d |
117 | |
118 | The values can be: |
119 | |
120 | =over 4 |
121 | |
122 | =item current |
123 | |
124 | Latest default style, whatever that happens to be. |
125 | |
126 | =item v5 |
127 | |
128 | Version 0.05XXX style. |
129 | |
130 | =item v4 |
131 | |
132 | Version 0.04XXX style. |
133 | |
134 | =back |
135 | |
136 | Dynamic schemas will always default to the 0.04XXX relationship names and won't |
137 | singularize Results for backward compatibility, to activate the new RelBuilder |
138 | and singularization put this in your C<Schema.pm> file: |
139 | |
140 | __PACKAGE__->naming('current'); |
141 | |
142 | Or if you prefer to use 0.05XXX features but insure that nothing breaks in the |
143 | next major version upgrade: |
144 | |
145 | __PACKAGE__->naming('v5'); |
146 | |
996be9ee |
147 | =head2 debug |
148 | |
149 | If set to true, each constructive L<DBIx::Class> statement the loader |
150 | decides to execute will be C<warn>-ed before execution. |
151 | |
d65cda9e |
152 | =head2 db_schema |
153 | |
154 | Set the name of the schema to load (schema in the sense that your database |
155 | vendor means it). Does not currently support loading more than one schema |
156 | name. |
157 | |
996be9ee |
158 | =head2 constraint |
159 | |
160 | Only load tables matching regex. Best specified as a qr// regex. |
161 | |
162 | =head2 exclude |
163 | |
164 | Exclude tables matching regex. Best specified as a qr// regex. |
165 | |
166 | =head2 moniker_map |
167 | |
8f9d7ce5 |
168 | Overrides the default table name to moniker translation. Can be either |
169 | a hashref of table keys and moniker values, or a coderef for a translator |
996be9ee |
170 | function taking a single scalar table name argument and returning |
171 | a scalar moniker. If the hash entry does not exist, or the function |
172 | returns a false value, the code falls back to default behavior |
173 | for that table name. |
174 | |
9cc8e7e1 |
175 | The default behavior is to singularize the table name, and: C<join '', map |
176 | ucfirst, split /[\W_]+/, lc $table>, which is to say: lowercase everything, |
177 | split up the table name into chunks anywhere a non-alpha-numeric character |
178 | occurs, change the case of first letter of each chunk to upper case, and put |
179 | the chunks back together. Examples: |
996be9ee |
180 | |
181 | Table Name | Moniker Name |
182 | --------------------------- |
183 | luser | Luser |
184 | luser_group | LuserGroup |
185 | luser-opts | LuserOpts |
186 | |
187 | =head2 inflect_plural |
188 | |
189 | Just like L</moniker_map> above (can be hash/code-ref, falls back to default |
190 | if hash key does not exist or coderef returns false), but acts as a map |
191 | for pluralizing relationship names. The default behavior is to utilize |
192 | L<Lingua::EN::Inflect::Number/to_PL>. |
193 | |
194 | =head2 inflect_singular |
195 | |
196 | As L</inflect_plural> above, but for singularizing relationship names. |
197 | Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>. |
198 | |
9c9c2f2b |
199 | =head2 schema_base_class |
200 | |
201 | Base class for your schema classes. Defaults to 'DBIx::Class::Schema'. |
202 | |
203 | =head2 result_base_class |
204 | |
2229729e |
205 | Base class for your table classes (aka result classes). Defaults to |
206 | 'DBIx::Class::Core'. |
9c9c2f2b |
207 | |
996be9ee |
208 | =head2 additional_base_classes |
209 | |
210 | List of additional base classes all of your table classes will use. |
211 | |
212 | =head2 left_base_classes |
213 | |
214 | List of additional base classes all of your table classes will use |
215 | that need to be leftmost. |
216 | |
217 | =head2 additional_classes |
218 | |
219 | List of additional classes which all of your table classes will use. |
220 | |
221 | =head2 components |
222 | |
223 | List of additional components to be loaded into all of your table |
224 | classes. A good example would be C<ResultSetManager>. |
225 | |
226 | =head2 resultset_components |
227 | |
8f9d7ce5 |
228 | List of additional ResultSet components to be loaded into your table |
996be9ee |
229 | classes. A good example would be C<AlwaysRS>. Component |
230 | C<ResultSetManager> will be automatically added to the above |
231 | C<components> list if this option is set. |
232 | |
f44ecc2f |
233 | =head2 use_namespaces |
234 | |
235 | Generate result class names suitable for |
236 | L<DBIx::Class::Schema/load_namespaces> and call that instead of |
237 | L<DBIx::Class::Schema/load_classes>. When using this option you can also |
238 | specify any of the options for C<load_namespaces> (i.e. C<result_namespace>, |
239 | C<resultset_namespace>, C<default_resultset_class>), and they will be added |
240 | to the call (and the generated result class names adjusted appropriately). |
241 | |
996be9ee |
242 | =head2 dump_directory |
243 | |
244 | This option is designed to be a tool to help you transition from this |
245 | loader to a manually-defined schema when you decide it's time to do so. |
246 | |
247 | The value of this option is a perl libdir pathname. Within |
248 | that directory this module will create a baseline manual |
249 | L<DBIx::Class::Schema> module set, based on what it creates at runtime |
250 | in memory. |
251 | |
252 | The created schema class will have the same classname as the one on |
253 | which you are setting this option (and the ResultSource classes will be |
7cab3ab7 |
254 | based on this name as well). |
996be9ee |
255 | |
8f9d7ce5 |
256 | Normally you wouldn't hard-code this setting in your schema class, as it |
996be9ee |
257 | is meant for one-time manual usage. |
258 | |
259 | See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the |
260 | recommended way to access this functionality. |
261 | |
d65cda9e |
262 | =head2 dump_overwrite |
263 | |
28b4691d |
264 | Deprecated. See L</really_erase_my_files> below, which does *not* mean |
265 | the same thing as the old C<dump_overwrite> setting from previous releases. |
266 | |
267 | =head2 really_erase_my_files |
268 | |
7cab3ab7 |
269 | Default false. If true, Loader will unconditionally delete any existing |
270 | files before creating the new ones from scratch when dumping a schema to disk. |
271 | |
272 | The default behavior is instead to only replace the top portion of the |
273 | file, up to and including the final stanza which contains |
274 | C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!> |
275 | leaving any customizations you placed after that as they were. |
276 | |
28b4691d |
277 | When C<really_erase_my_files> is not set, if the output file already exists, |
7cab3ab7 |
278 | but the aforementioned final stanza is not found, or the checksum |
279 | contained there does not match the generated contents, Loader will |
280 | croak and not touch the file. |
d65cda9e |
281 | |
28b4691d |
282 | You should really be using version control on your schema classes (and all |
283 | of the rest of your code for that matter). Don't blame me if a bug in this |
284 | code wipes something out when it shouldn't have, you've been warned. |
285 | |

286 | =head1 METHODS |
287 | |

289 | users of L<DBIx::Class::Schema::Loader>. Anything you can find here |
290 | can also be found via standard L<DBIx::Class::Schema> methods somehow. |
