64 | =head1 DESCRIPTION | ||||
65 | |||||
66 | A ResultSource is an object that represents a source of data for querying. | ||||
67 | |||||
68 | This class is a base class for various specialised types of result | ||||
69 | sources, for example L<DBIx::Class::ResultSource::Table>. Table is the | ||||
70 | default result source type, so one is created for you when defining a | ||||
71 | result class as described in the synopsis above. | ||||
72 | |||||
73 | More specifically, the L<DBIx::Class::Core> base class pulls in the | ||||
74 | L<DBIx::Class::ResultSourceProxy::Table> component, which defines | ||||
75 | the L<table|DBIx::Class::ResultSourceProxy::Table/table> method. | ||||
76 | When called, C<table> creates and stores an instance of | ||||
77 | L<DBIx::Class::ResultSoure::Table>. Luckily, to use tables as result | ||||
78 | sources, you don't need to remember any of this. | ||||
79 | |||||
80 | Result sources representing select queries, or views, can also be | ||||
81 | created, see L<DBIx::Class::ResultSource::View> for full details. | ||||
82 | |||||
83 | =head2 Finding result source objects | ||||
84 | |||||
85 | As mentioned above, a result source instance is created and stored for | ||||
86 | you when you define a L<Result Class|DBIx::Class::Manual::Glossary/Result Class>. | ||||
87 | |||||
88 | You can retrieve the result source at runtime in the following ways: | ||||
89 | |||||
90 | =over | ||||
91 | |||||
92 | =item From a Schema object: | ||||
93 | |||||
94 | $schema->source($source_name); | ||||
95 | |||||
96 | =item From a Row object: | ||||
97 | |||||
98 | $row->result_source; | ||||
99 | |||||
100 | =item From a ResultSet object: | ||||

102 | $rs->result_source; | ||||

139 | $source->add_columns(qw/col1 col2 col3/); | ||||
140 | |||||
141 | $source->add_columns('col1' => \%col1_info, 'col2' => \%col2_info, ...); | ||||
142 | |||||
143 | Adds columns to the result source. If supplied colname => hashref | ||||
144 | pairs, uses the hashref as the L</column_info> for that column. Repeated | ||||
145 | calls of this method will add more columns, not replace them. | ||||
146 | |||||
147 | The column names given will be created as accessor methods on your | ||||
148 | L<DBIx::Class::Row> objects. You can change the name of the accessor | ||||
149 | by supplying an L</accessor> in the column_info hash. | ||||
150 | |||||
151 | If a column name beginning with a plus sign ('+col1') is provided, the | ||||
152 | attributes provided will be merged with any existing attributes for the | ||||
153 | column, with the new attributes taking precedence in the case that an | ||||
154 | attribute already exists. Using this without a hashref | ||||
155 | (C<< $source->add_columns(qw/+col1 +col2/) >>) is legal, but useless -- | ||||
156 | it does the same thing it would do without the plus. | ||||
157 | |||||
158 | The contents of the column_info are not set in stone. The following | ||||
159 | keys are currently recognised/used by DBIx::Class: | ||||
160 | |||||
161 | =over 4 | ||||
162 | |||||
163 | =item accessor | ||||
164 | |||||
165 | { accessor => '_name' } | ||||
166 | |||||
167 | # example use, replace standard accessor with one of your own: | ||||
168 | sub name { | ||||
169 | my ($self, $value) = @_; | ||||
170 | |||||
171 | die "Name cannot contain digits!" if($value =~ /\d/); | ||||
172 | $self->_name($value); | ||||
173 | |||||
174 | return $self->_name(); | ||||
175 | } | ||||
176 | |||||
177 | Use this to set the name of the accessor method for this column. If unset, | ||||
178 | the name of the column will be used. | ||||
179 | |||||
180 | =item data_type | ||||
181 | |||||
182 | { data_type => 'integer' } | ||||
183 | |||||
184 | This contains the column type. It is automatically filled if you use the | ||||
185 | L<SQL::Translator::Producer::DBIx::Class::File> producer, or the | ||||
186 | L<DBIx::Class::Schema::Loader> module. | ||||
187 | |||||
188 | Currently there is no standard set of values for the data_type. Use | ||||
189 | whatever your database supports. | ||||
190 | |||||
191 | =item size | ||||
192 | |||||
193 | { size => 20 } | ||||
194 | |||||
195 | The length of your column, if it is a column type that can have a size | ||||
196 | restriction. This is currently only used to create tables from your | ||||
197 | schema, see L<DBIx::Class::Schema/deploy>. | ||||
198 | |||||
199 | =item is_nullable | ||||
200 | |||||
201 | { is_nullable => 1 } | ||||
202 | |||||
203 | Set this to a true value for a columns that is allowed to contain NULL | ||||
204 | values, default is false. This is currently only used to create tables | ||||
205 | from your schema, see L<DBIx::Class::Schema/deploy>. | ||||
206 | |||||
207 | =item is_auto_increment | ||||
208 | |||||
209 | { is_auto_increment => 1 } | ||||
210 | |||||
211 | Set this to a true value for a column whose value is somehow | ||||
212 | automatically set, defaults to false. This is used to determine which | ||||
213 | columns to empty when cloning objects using | ||||
214 | L<DBIx::Class::Row/copy>. It is also used by | ||||
215 | L<DBIx::Class::Schema/deploy>. | ||||
216 | |||||
217 | =item is_numeric | ||||
218 | |||||
219 | { is_numeric => 1 } | ||||
220 | |||||
221 | Set this to a true or false value (not C<undef>) to explicitly specify | ||||
222 | if this column contains numeric data. This controls how set_column | ||||
223 | decides whether to consider a column dirty after an update: if | ||||
224 | C<is_numeric> is true a numeric comparison C<< != >> will take place | ||||
225 | instead of the usual C<eq> | ||||
226 | |||||
227 | If not specified the storage class will attempt to figure this out on | ||||
228 | first access to the column, based on the column C<data_type>. The | ||||
229 | result will be cached in this attribute. | ||||
230 | |||||
231 | =item is_foreign_key | ||||
232 | |||||
233 | { is_foreign_key => 1 } | ||||
234 | |||||
235 | Set this to a true value for a column that contains a key from a | ||||
236 | foreign table, defaults to false. This is currently only used to | ||||
237 | create tables from your schema, see L<DBIx::Class::Schema/deploy>. | ||||
238 | |||||
239 | =item default_value | ||||
240 | |||||
241 | { default_value => \'now()' } | ||||
242 | |||||
243 | Set this to the default value which will be inserted into a column by | ||||
244 | the database. Can contain either a value or a function (use a | ||||
245 | reference to a scalar e.g. C<\'now()'> if you want a function). This | ||||
246 | is currently only used to create tables from your schema, see | ||||
247 | L<DBIx::Class::Schema/deploy>. | ||||
248 | |||||
249 | See the note on L<DBIx::Class::Row/new> for more information about possible | ||||
250 | issues related to db-side default values. | ||||
251 | |||||
252 | =item sequence | ||||
253 | |||||
254 | { sequence => 'my_table_seq' } | ||||
255 | |||||
256 | Set this on a primary key column to the name of the sequence used to | ||||
257 | generate a new key value. If not specified, L<DBIx::Class::PK::Auto> | ||||
258 | will attempt to retrieve the name of the sequence from the database | ||||
259 | automatically. | ||||
260 | |||||
261 | =item retrieve_on_insert | ||||
262 | |||||
263 | { retrieve_on_insert => 1 } | ||||
264 | |||||
265 | For every column where this is set to true, DBIC will retrieve the RDBMS-side | ||||
266 | value upon a new row insertion (normally only the autoincrement PK is | ||||
267 | retrieved on insert). C<INSERT ... RETURNING> is used automatically if | ||||
268 | supported by the underlying storage, otherwise an extra SELECT statement is | ||||
269 | executed to retrieve the missing data. | ||||
270 | |||||
271 | =item auto_nextval | ||||
272 | |||||
273 | { auto_nextval => 1 } | ||||
274 | |||||
275 | Set this to a true value for a column whose value is retrieved automatically | ||||
276 | from a sequence or function (if supported by your Storage driver.) For a | ||||
277 | sequence, if you do not use a trigger to get the nextval, you have to set the | ||||
278 | L</sequence> value as well. | ||||
279 | |||||
280 | Also set this for MSSQL columns with the 'uniqueidentifier' | ||||
281 | L<data_type|DBIx::Class::ResultSource/data_type> whose values you want to | ||||
282 | automatically generate using C<NEWID()>, unless they are a primary key in which | ||||
283 | case this will be done anyway. | ||||
284 | |||||
285 | =item extra | ||||
286 | |||||
287 | This is used by L<DBIx::Class::Schema/deploy> and L<SQL::Translator> | ||||
288 | to add extra non-generic data to the column. For example: C<< extra | ||||
289 | => { unsigned => 1} >> is used by the MySQL producer to set an integer | ||||
290 | column to unsigned. For more details, see | ||||
291 | L<SQL::Translator::Producer::MySQL>. | ||||

1167 | |||||
1168 | L<DBIx::Class::Relationship> describes a series of methods which | ||||
1169 | create pre-defined useful types of relationships. Look there first | ||||
1170 | before using this method directly. | ||||
1171 | |||||
1172 | The relationship name can be arbitrary, but must be unique for each | ||||
1173 | relationship attached to this result source. 'related_source' should | ||||
1174 | be the name with which the related result source was registered with | ||||
1175 | the current schema. For example: | ||||
1176 | |||||
1177 | $schema->source('Book')->add_relationship('reviews', 'Review', { | ||||
1178 | 'foreign.book_id' => 'self.id', | ||||
1179 | }); | ||||
1180 | |||||
1181 | The condition C<$cond> needs to be an L<SQL::Abstract>-style | ||||
1182 | representation of the join between the tables. For example, if you're | ||||
1183 | creating a relation from Author to Book, | ||||
1184 | |||||
1185 | { 'foreign.author_id' => 'self.id' } | ||||
1186 | |||||
1187 | will result in the JOIN clause | ||||
1188 | |||||
1189 | author me JOIN book foreign ON foreign.author_id = me.id | ||||
1190 | |||||
1191 | You can specify as many foreign => self mappings as necessary. | ||||
1192 | |||||
1193 | Valid attributes are as follows: | ||||
1194 | |||||
1195 | =over 4 | ||||
1196 | |||||
1197 | =item join_type | ||||
1198 | |||||
1199 | Explicitly specifies the type of join to use in the relationship. Any | ||||
1200 | SQL join type is valid, e.g. C<LEFT> or C<RIGHT>. It will be placed in | ||||
1201 | the SQL command immediately before C<JOIN>. | ||||
1202 | |||||
1203 | =item proxy | ||||
1204 | |||||
1205 | An arrayref containing a list of accessors in the foreign class to proxy in | ||||
1206 | the main class. If, for example, you do the following: | ||||
1207 | |||||
1208 | CD->might_have(liner_notes => 'LinerNotes', undef, { | ||||
1209 | proxy => [ qw/notes/ ], | ||||
1210 | }); | ||||
1211 | |||||
1212 | Then, assuming LinerNotes has an accessor named notes, you can do: | ||||
1213 | |||||
1214 | my $cd = CD->find(1); | ||||
1215 | # set notes -- LinerNotes object is created if it doesn't exist | ||||
1216 | $cd->notes('Notes go here'); | ||||
1217 | |||||
1218 | =item accessor | ||||
1219 | |||||
1220 | Specifies the type of accessor that should be created for the | ||||
1221 | relationship. Valid values are C<single> (for when there is only a single | ||||
1222 | related object), C<multi> (when there can be many), and C<filter> (for | ||||
1223 | when there is a single related object, but you also want the relationship | ||||
1224 | accessor to double as a column accessor). For C<multi> accessors, an | ||||
1225 | add_to_* method is also created, which calls C<create_related> for the | ||||
1226 | relationship. | ||||
