43 | =head1 NAME |
44 | |
45 | DBIx::Class::Schema::Loader::Base - Base DBIx::Class::Schema::Loader Implementation. |
46 | |
47 | =head1 SYNOPSIS |
48 | |
49 | See L<DBIx::Class::Schema::Loader> |
50 | |
51 | =head1 DESCRIPTION |
52 | |
53 | This is the base class for the storage-specific C<DBIx::Class::Schema::*> |
54 | classes, and implements the common functionality between them. |
55 | |
56 | =head1 CONSTRUCTOR OPTIONS |
57 | |
58 | These constructor options are the base options for |
59 | L<DBIx::Class::Schema::Loader/loader_opts>. Available constructor options are: |
60 | |
61 | =head2 relationships |
62 | |
63 | Try to automatically detect/setup has_a and has_many relationships. |
64 | |
65 | =head2 debug |
66 | |
67 | If set to true, each constructive L<DBIx::Class> statement the loader |
68 | decides to execute will be C<warn>-ed before execution. |
69 | |
d65cda9e |
70 | =head2 db_schema |
71 | |
72 | Set the name of the schema to load (schema in the sense that your database |
73 | vendor means it). Does not currently support loading more than one schema |
74 | name. |
75 | |
996be9ee |
76 | =head2 constraint |
77 | |
78 | Only load tables matching regex. Best specified as a qr// regex. |
79 | |
80 | =head2 exclude |
81 | |
82 | Exclude tables matching regex. Best specified as a qr// regex. |
83 | |
84 | =head2 moniker_map |
85 | |
8f9d7ce5 |
86 | Overrides the default table name to moniker translation. Can be either |
87 | a hashref of table keys and moniker values, or a coderef for a translator |
996be9ee |
88 | function taking a single scalar table name argument and returning |
89 | a scalar moniker. If the hash entry does not exist, or the function |
90 | returns a false value, the code falls back to default behavior |
91 | for that table name. |
92 | |
93 | The default behavior is: C<join '', map ucfirst, split /[\W_]+/, lc $table>, |
94 | which is to say: lowercase everything, split up the table name into chunks |
95 | anywhere a non-alpha-numeric character occurs, change the case of first letter |
96 | of each chunk to upper case, and put the chunks back together. Examples: |
97 | |
98 | Table Name | Moniker Name |
99 | --------------------------- |
100 | luser | Luser |
101 | luser_group | LuserGroup |
102 | luser-opts | LuserOpts |
103 | |
104 | =head2 inflect_plural |
105 | |
106 | Just like L</moniker_map> above (can be hash/code-ref, falls back to default |
107 | if hash key does not exist or coderef returns false), but acts as a map |
108 | for pluralizing relationship names. The default behavior is to utilize |
109 | L<Lingua::EN::Inflect::Number/to_PL>. |
110 | |
111 | =head2 inflect_singular |
112 | |
113 | As L</inflect_plural> above, but for singularizing relationship names. |
114 | Default behavior is to utilize L<Lingua::EN::Inflect::Number/to_S>. |
115 | |
116 | =head2 additional_base_classes |
117 | |
118 | List of additional base classes all of your table classes will use. |
119 | |
120 | =head2 left_base_classes |
121 | |
122 | List of additional base classes all of your table classes will use |
123 | that need to be leftmost. |
124 | |
125 | =head2 additional_classes |
126 | |
127 | List of additional classes which all of your table classes will use. |
128 | |
129 | =head2 components |
130 | |
131 | List of additional components to be loaded into all of your table |
132 | classes. A good example would be C<ResultSetManager>. |
133 | |
134 | =head2 resultset_components |
135 | |
8f9d7ce5 |
136 | List of additional ResultSet components to be loaded into your table |
996be9ee |
137 | classes. A good example would be C<AlwaysRS>. Component |
138 | C<ResultSetManager> will be automatically added to the above |
139 | C<components> list if this option is set. |
140 | |
141 | =head2 legacy_default_inflections |
142 | |
143 | Setting this option changes the default fallback for L</inflect_plural> to |
8f9d7ce5 |
144 | utilize L<Lingua::EN::Inflect/PL>, and L</inflect_singular> to a no-op. |
145 | Those choices produce substandard results, but might be necessary to support |
996be9ee |
146 | your existing code if you started developing on a version prior to 0.03 and |
147 | don't wish to go around updating all your relationship names to the new |
148 | defaults. |
149 | |
d65cda9e |
150 | This option will continue to be supported until at least version 0.05xxx, |
151 | but may dissappear sometime thereafter. It is recommended that you update |
152 | your code to use the newer-style inflections when you have the time. |
153 | |
996be9ee |
154 | =head2 dump_directory |
155 | |
156 | This option is designed to be a tool to help you transition from this |
157 | loader to a manually-defined schema when you decide it's time to do so. |
158 | |
159 | The value of this option is a perl libdir pathname. Within |
160 | that directory this module will create a baseline manual |
161 | L<DBIx::Class::Schema> module set, based on what it creates at runtime |
162 | in memory. |
163 | |
164 | The created schema class will have the same classname as the one on |
165 | which you are setting this option (and the ResultSource classes will be |
166 | based on this name as well). Therefore it is wise to note that if you |
167 | point the C<dump_directory> option of a schema class at the live libdir |
168 | where that class is currently located, it will overwrite itself with a |
169 | manual version of itself. This might be a really good or bad thing |
170 | depending on your situation and perspective. |
171 | |
8f9d7ce5 |
172 | Normally you wouldn't hard-code this setting in your schema class, as it |
996be9ee |
173 | is meant for one-time manual usage. |
174 | |
175 | See L<DBIx::Class::Schema::Loader/dump_to_dir> for examples of the |
176 | recommended way to access this functionality. |
177 | |
d65cda9e |
178 | =head2 dump_overwrite |
179 | |
180 | If set to a true value, the dumping code will overwrite existing files. |
02356864 |
181 | The default is false, which means the dumping code will skip the already |
182 | existing files. |

197 | |
198 | You connect these schemas the same way you would any L<DBIx::Class::Schema>, |
199 | which is by calling either C<connect> or C<connection> on a schema class |
200 | or object. These options are only supported via the deprecated |
d65cda9e |
201 | C<load_from_connection> interface, which is also being removed in 0.04000. |
996be9ee |

203 | =head1 METHODS |
204 | |
205 | None of these methods are intended for direct invocation by regular |
206 | users of L<DBIx::Class::Schema::Loader>. Anything you can find here |
207 | can also be found via standard L<DBIx::Class::Schema> methods somehow. |
