55 DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation.
59 See L<DBIx::Class::Schema::Loader>
63 This is the base class for the storage-specific C<DBIx::Class::Schema::*>
64 classes, and implements the common functionality between them.
66 =head1 CONSTRUCTOR OPTIONS
68 These constructor options are the base options for
69 L<DBIx::Class::Schema::Loader/loader_options>. Available constructor options are:
71 =head2 skip_relationships
73 Skip setting up relationships. The default is to attempt the loading
78 If set to true, each constructive L<DBIx::Class> statement the loader
79 decides to execute will be C<warn>-ed before execution.
83 Set the name of the schema to load (schema in the sense that your database
84 vendor means it). Does not currently support loading more than one schema
89 Only load tables matching regex. Best specified as a qr// regex.
93 Exclude tables matching regex. Best specified as a qr// regex.
97 Overrides the default table name to moniker translation. Can be either
98 a hashref of table keys and moniker values, or a coderef for a translator
99 function taking a single scalar table name argument and returning
100 a scalar moniker. If the hash entry does not exist, or the function
101 returns a false value, the code falls back to default behavior
104 The default behavior is: C<join '', map ucfirst, split /[\W_]+/, lc $table>,
105 which is to say: lowercase everything, split up the table name into chunks
106 anywhere a non-alpha-numeric character occurs, change the case of first letter
107 of each chunk to upper case, and put the chunks back together. Examples:
109 Table Name | Moniker Name
110 ---------------------------
112 luser_group | LuserGroup
113 luser-opts | LuserOpts
115 =head2 inflect_plural
117 Just like L</moniker_map> above (can be hash/code-ref, falls back to default
118 if hash key does not exist or coderef returns false), but acts as a map
119 for pluralizing relationship names. The default behavior is to utilize
120 L<Lingua::EN::Inflect::Number/to_PL>.
122 =head2 inflect_singular
124 As L</inflect_plural> above, but for singularizing relationship names.
125 Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>.
127 =head2 schema_base_class
129 Base class for your schema classes. Defaults to 'DBIx::Class::Schema'.
131 =head2 result_base_class
133 Base class for your table classes (aka result classes). Defaults to
136 =head2 additional_base_classes
138 List of additional base classes all of your table classes will use.
140 =head2 left_base_classes
142 List of additional base classes all of your table classes will use
143 that need to be leftmost.
145 =head2 additional_classes
147 List of additional classes which all of your table classes will use.
151 List of additional components to be loaded into all of your table
152 classes. A good example would be C<ResultSetManager>.
154 =head2 resultset_components
156 List of additional ResultSet components to be loaded into your table
157 classes. A good example would be C<AlwaysRS>. Component
158 C<ResultSetManager> will be automatically added to the above
159 C<components> list if this option is set.
161 =head2 use_namespaces
163 Generate result class names suitable for
164 L<DBIx::Class::Schema/load_namespaces> and call that instead of
165 L<DBIx::Class::Schema/load_classes>. When using this option you can also
166 specify any of the options for C<load_namespaces> (i.e. C<result_namespace>,
167 C<resultset_namespace>, C<default_resultset_class>), and they will be added
168 to the call (and the generated result class names adjusted appropriately).
170 =head2 dump_directory
172 This option is designed to be a tool to help you transition from this
173 loader to a manually-defined schema when you decide it's time to do so.
175 The value of this option is a perl libdir pathname. Within
176 that directory this module will create a baseline manual
177 L<DBIx::Class::Schema> module set, based on what it creates at runtime
180 The created schema class will have the same classname as the one on
181 which you are setting this option (and the ResultSource classes will be
182 based on this name as well).
184 Normally you wouldn't hard-code this setting in your schema class, as it
185 is meant for one-time manual usage.
187 See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the
188 recommended way to access this functionality.
190 =head2 dump_overwrite
192 Deprecated. See L</really_erase_my_files> below, which does *not* mean
193 the same thing as the old C<dump_overwrite> setting from previous releases.
195 =head2 really_erase_my_files
197 Default false. If true, Loader will unconditionally delete any existing
198 files before creating the new ones from scratch when dumping a schema to disk.
200 The default behavior is instead to only replace the top portion of the
201 file, up to and including the final stanza which contains
202 C<# DO NOT MODIFY THIS OR ANYTHING ABOVE!>
203 leaving any customizations you placed after that as they were.
205 When C<really_erase_my_files> is not set, if the output file already exists,
206 but the aforementioned final stanza is not found, or the checksum
207 contained there does not match the generated contents, Loader will
208 croak and not touch the file.
210 You should really be using version control on your schema classes (and all
211 of the rest of your code for that matter). Don't blame me if a bug in this
212 code wipes something out when it shouldn't have, you've been warned.
216 None of these methods are intended for direct invocation by regular
217 users of L<DBIx::Class::Schema::Loader>. Anything you can find here
218 can also be found via standard L<DBIx::Class::Schema> methods somehow.

944 Returns a hashref of loaded table to moniker mappings. There will
945 be two entries for each table, the original name and the "normalized"
946 name, in the case that the two are different (such as databases
947 that like uppercase table names, or preserve your original mixed-case
948 definitions, or what-have-you).
952 Returns a hashref of table to class mappings. In some cases it will
953 contain multiple entries per table for the original and normalized table
954 names, as above in L</monikers>.
