41 config_dir => '/home/me/app/fixture_configs'
45 config => 'set_config.json',

59 Dump fixtures from source database to filesystem then import to another
60 database (with same schema) at any time. Use as a constant dataset for running
61 tests against or for populating development databases when impractical to use
62 production clones. Describe fixture set using relations and conditions based on
63 your DBIx::Class schema.
65 =head1 DEFINE YOUR FIXTURE SET
67 Fixture sets are currently defined in .json files which must reside in your
68 config_dir (e.g. /home/me/app/fixture_configs/a_fixture_set.json). They
69 describe which data to pull and dump from the source database.
92 This will fetch artists with primary keys 1 and 3, the producer with primary
93 key 5 and two of producer 5's artists where 'artists' is a has_many DBIx::Class
94 rel from Producer to Artist.
96 The top level attributes are as follows:
100 Sets must be an array of hashes, as in the example given above. Each set
101 defines a set of objects to be included in the fixtures. For details on valid
102 set attributes see L</SET ATTRIBUTES> below.
106 Rules place general conditions on classes. For example if whenever an artist
107 was dumped you also wanted all of their cds dumped too, then you could use a
108 rule to specify this. For example:
137 In this case all the cds of artists 1, 3 and all producer 5's artists will be
138 dumped as well. Note that 'cds' is a has_many DBIx::Class relation from Artist
139 to CD. This is eqivalent to:
166 rules must be a hash keyed by class name.
172 To prevent repetition between configs you can include other configs. For
181 { "file": "base.json" }
185 Includes must be an arrayref of hashrefs where the hashrefs have key 'file'
186 which is the name of another config file in the same directory. The original
187 config is merged with its includes using L<Hash::Merge>.
189 =head2 datetime_relative
191 Only available for MySQL and PostgreSQL at the moment, must be a value that
192 DateTime::Format::* can parse. For example:
196 "class": "RecentItems",
199 "datetime_relative": "2007-10-30 00:00:00"
202 This will work when dumping from a MySQL database and will cause any datetime
203 fields (where datatype => 'datetime' in the column def of the schema class) to
204 be dumped as a DateTime::Duration object relative to the date specified in the
205 datetime_relative value. For example if the RecentItem object had a date field
206 set to 2007-10-25, then when the fixture is imported the field will be set to 5
207 days in the past relative to the current time.
211 Specifies whether to automatically dump might_have relationships. Should be a
212 hash with one attribute - fetch. Set fetch to 1 or 0.
215 "might_have": { "fetch": 1 },
228 Note: belongs_to rels are automatically dumped whether you like it or not, this
229 is to avoid FKs to nowhere when importing. General rules on has_many rels are
230 not accepted at this top level, but you can turn them on for individual sets -
231 see L</SET ATTRIBUTES>.
233 =head1 SET ATTRIBUTES
237 Required attribute. Specifies the DBIx::Class object class you wish to dump.
241 Array of primary key ids to fetch, basically causing an $rs->find($_) for each.
242 If the id is not in the source db then it just won't get dumped, no warnings or
247 Must be either an integer or the string 'all'. Specifying an integer will
248 effectively set the 'rows' attribute on the resultset clause, specifying 'all'
249 will cause the rows attribute to be left off and for all matching rows to be
250 dumped. There's no randomising here, it's just the first x rows.
254 A hash specifying the conditions dumped objects must match. Essentially this is
255 a JSON representation of a DBIx::Class search clause. For example:
261 "cond": { "name": "Dave" }
265 This will dump all artists whose name is 'dave'. Essentially
266 $artist_rs->search({ name => 'Dave' })->all.
268 Sometimes in a search clause it's useful to use scalar refs to do things like:
270 $artist_rs->search({ no1_singles => \'> no1_albums' })
272 This could be specified in the cond hash like so:
278 "cond": { "no1_singles": "\> no1_albums" }
282 So if the value starts with a backslash the value is made a scalar ref before
283 being passed to search.
287 An array of relationships to be used in the cond clause.
293 "cond": { "cds.position": { ">": 4 } },
298 Fetch all artists who have cds with position greater than 4.
302 Must be an array of hashes. Specifies which rels to also dump. For example:
311 "cond": { "position": "2" }
316 Will cause the cds of artists 1 and 3 to be dumped where the cd position is 2.
318 Valid attributes are: 'rel', 'quantity', 'cond', 'has_many', 'might_have' and
319 'join'. rel is the name of the DBIx::Class rel to follow, the rest are the same
320 as in the set attributes. quantity is necessary for has_many relationships, but
321 not if using for belongs_to or might_have relationships.
325 Specifies whether to fetch has_many rels for this set. Must be a hash
326 containing keys fetch and quantity.
328 Set fetch to 1 if you want to fetch them, and quantity to either 'all' or an
331 Be careful here, dumping has_many rels can lead to a lot of data being dumped.
335 As with has_many but for might_have relationships. Quantity doesn't do anything
338 This value will be inherited by all fetches in this set. This is not true for
339 the has_many attribute.
343 In some cases your database information might be keys to values in some sort of
344 external storage. The classic example is you are using L<DBIx::Class::InflateColumn::FS>
345 to store blob information on the filesystem. In this case you may wish the ability
346 to backup your external storage in the same way your database data. The L</external>
347 attribute lets you specify a handler for this type of issue. For example:
356 "args": {"path":"__ATTR(photo_dir)__"}
362 This would use L<DBIx::Class::Fixtures::External::File> to read from a directory
363 where the path to a file is specified by the C<file> field of the C<Photo> source.
364 We use the uninflated value of the field so you need to completely handle backup
365 and restore. For the common case we provide L<DBIx::Class::Fixtures::External::File>
366 and you can create your own custom handlers by placing a '+' in the namespace:
368 "class": "+MyApp::Schema::SomeExternalStorage",
370 Although if possible I'd love to get patches to add some of the other common
371 types (I imagine storage in MogileFS, Redis, etc or even Amazon might be popular.)
373 See L<DBIx::Class::Fixtures::External::File> for the external handler interface.

415 Provide a value from L</config_attrs>

1205 In this case the database app_dev will be cleared of all tables, then the
1206 specified DDL deployed to it, then finally all fixtures found in
1207 /home/me/app/fixtures will be added to it. populate will generate its own
1208 DBIx::Class schema from the DDL rather than being passed one to use. This is
1209 better as custom insert methods are avoided which can to get in the way. In
1210 some cases you might not have a DDL, and so this method will eventually allow a
1211 $schema object to be passed instead.
1213 If needed, you can specify a post_ddl attribute which is a DDL to be applied
1214 after all the fixtures have been added to the database. A good use of this
1215 option would be to add foreign key constraints since databases like Postgresql
1216 cannot disable foreign key checks.
1218 If your tables have foreign key constraints you may want to use the cascade
1219 attribute which will make the drop table functionality cascade, ie 'DROP TABLE
1222 C<directory> is a required attribute.
1224 If you wish for DBIx::Class::Fixtures to clear the database for you pass in
1225 C<dll> (path to a DDL sql file) and C<connection_details> (array ref of DSN,
1228 If you wish to deal with cleaning the schema yourself, then pass in a C<schema>
1229 attribute containing the connected schema you wish to operate on and set the
1230 C<no_deploy> attribute.
