37. Fixtures.

|
|
|
Fixtures are a way of loading data into the database in bulk. Fixure data
|
|
can be stored in any serializable format (including JSON and XML). Fixtures
|
|
are identified by name, and are stored in either a directory named 'fixtures'
|
|
in the application directory, on in one of the directories named in the
|
|
``FIXTURE_DIRS`` setting.
