59 DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.
63 See L<DBIx::Class::Schema::Loader>
67 This is the base class for the storage-specific C<DBIx::Class::Schema::*>
68 classes, and implements the common functionality between them.
70 =head1 CONSTRUCTOR OPTIONS
72 These constructor options are the base options for
73 L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are:
75 =head2 skip_relationships
77 Skip setting up relationships. The default is to attempt the loading
82 Static schemas (ones dumped to disk) will, by default, use the new-style 0.05XXX
83 relationship names and singularized Results, unless you're overwriting an
84 existing dump made by a 0.04XXX version of L<DBIx::Class::Schema::Loader>, in
85 which case the backward compatible RelBuilder will be activated, and
86 singularization will be turned off.
92 will disable the backward-compatible RelBuilder and use
93 the new-style relationship names along with singularized Results, even when
94 overwriting a dump made with an earlier version.
96 The option also takes a hashref:
98 naming => { relationships => 'v5', results => 'v4' }
106 Latest default style, whatever that happens to be.
110 Version 0.05XXX style.
114 Version 0.04XXX style.
118 Dynamic schemas will always default to the 0.04XXX relationship names and won't
119 singularize Results for backward compatibility, to activate the new RelBuilder
120 and singularization put this in your C<Schema.pm> file:
122 __PACKAGE__->naming('current');
124 Or if you prefer to use 0.05XXX features but insure that nothing breaks in the
125 next major version upgrade:
127 __PACKAGE__->naming('v5');
131 If set to true, each constructive L<DBIx::Class> statement the loader
132 decides to execute will be C<warn>-ed before execution.
136 Set the name of the schema to load (schema in the sense that your database
137 vendor means it). Does not currently support loading more than one schema
142 Only load tables matching regex. Best specified as a qr// regex.
146 Exclude tables matching regex. Best specified as a qr// regex.
150 Overrides the default table name to moniker translation. Can be either
151 a hashref of table keys and moniker values, or a coderef for a translator
152 function taking a single scalar table name argument and returning
153 a scalar moniker. If the hash entry does not exist, or the function
154 returns a false value, the code falls back to default behavior
157 The default behavior is: C<join '', map ucfirst, split /[\W_]+/, lc $table>,
158 which is to say: lowercase everything, split up the table name into chunks
159 anywhere a non-alpha-numeric character occurs, change the case of first letter
160 of each chunk to upper case, and put the chunks back together. Examples:
162 Table Name | Moniker Name
163 ---------------------------
165 luser_group | LuserGroup
166 luser-opts | LuserOpts
168 =head2 inflect_plural
170 Just like L</moniker_map> above (can be hash/code-ref, falls back to default
171 if hash key does not exist or coderef returns false), but acts as a map
172 for pluralizing relationship names. The default behavior is to utilize
173 L<Lingua::EN::Inflect::Number/to_PL>.
175 =head2 inflect_singular
177 As L</inflect_plural> above, but for singularizing relationship names.
178 Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>.
180 =head2 schema_base_class
182 Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
184 =head2 result_base_class
186 Base class for your table classes (aka result classes). Defaults to 'DBIx::Class'.
188 =head2 additional_base_classes
190 List of additional base classes all of your table classes will use.
192 =head2 left_base_classes
194 List of additional base classes all of your table classes will use
195 that need to be leftmost.
197 =head2 additional_classes
199 List of additional classes which all of your table classes will use.
203 List of additional components to be loaded into all of your table
204 classes. A good example would be C<ResultSetManager>.
206 =head2 resultset_components
208 List of additional ResultSet components to be loaded into your table
209 classes. A good example would be C<AlwaysRS>. Component
210 C<ResultSetManager> will be automatically added to the above
211 C<components> list if this option is set.
213 =head2 use_namespaces
215 Generate result class names suitable for
216 L<DBIx::Class::Schema/load_namespaces> and call that instead of
217 L<DBIx::Class::Schema/load_classes>. When using this option you can also
218 specify any of the options for C<load_namespaces> (i.e. C<result_namespace>,
219 C<resultset_namespace>, C<default_resultset_class>), and they will be added
220 to the call (and the generated result class names adjusted appropriately).
222 =head2 dump_directory
224 This option is designed to be a tool to help you transition from this
225 loader to a manually-defined schema when you decide it's time to do so.
227 The value of this option is a perl libdir pathname. Within
228 that directory this module will create a baseline manual
229 L<DBIx::Class::Schema> module set, based on what it creates at runtime
232 The created schema class will have the same classname as the one on
233 which you are setting this option (and the ResultSource classes will be
234 based on this name as well).
236 Normally you wouldn't hard-code this setting in your schema class, as it
237 is meant for one-time manual usage.
239 See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the
240 recommended way to access this functionality.
242 =head2 dump_overwrite
244 Deprecated. See L</really_erase_my_files> below, which does *not* mean
245 the same thing as the old C<dump_overwrite> setting from previous releases.
247 =head2 really_erase_my_files
249 Default false. If true, Loader will unconditionally delete any existing
250 files before creating the new ones from scratch when dumping a schema to disk.
252 The default behavior is instead to only replace the top portion of the
253 file, up to and including the final stanza which contains
254 C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!>
255 leaving any customizations you placed after that as they were.
257 When C<really_erase_my_files> is not set, if the output file already exists,
258 but the aforementioned final stanza is not found, or the checksum
259 contained there does not match the generated contents, Loader will
260 croak and not touch the file.
262 You should really be using version control on your schema classes (and all
263 of the rest of your code for that matter). Don't blame me if a bug in this
264 code wipes something out when it shouldn't have, you've been warned.
268 None of these methods are intended for direct invocation by regular
269 users of L<DBIx::Class::Schema::Loader>. Anything you can find here
270 can also be found via standard L<DBIx::Class::Schema> methods somehow.

1003 Returns a hashref of loaded table to moniker mappings. There will
1004 be two entries for each table, the original name and the "normalized"
1005 name, in the case that the two are different (such as databases
1006 that like uppercase table names, or preserve your original mixed-case
1007 definitions, or what-have-you).
1011 Returns a hashref of table to class mappings. In some cases it will
1012 contain multiple entries per table for the original and normalized table
1013 names, as above in L</monikers>.
