Very simple example of fixtures

Fixtures

+''It is very simple example, please, read something more complex if you need.''

+Fixtures are very powerful to play with your database sample data during development process.
+After each '''python manage.py reset <myapp>''' command you need to populate database with sample data again and again using admin interface. It's quite boring, isn't it?
+With fixtures our life became more comfortable and easy. Look at this example.
+Lets imagine that you have some data in db, so we can dump it. Even if your models have ForeignKeys or any kind of *To* relations.
+
+First we need to define fixtures dir in settings file:
+
+{{{
+FIXTURE_DIRS = (
+   '/path/to/myapp/fixtures/',
+)
+}}}
+
+Lets dump our data:
+
+{{{
+cd /path/to/myapp/fixtures
+python manage.py dumpdata --format=json myapp > initial_data.json
+}}}
+
+Reset:
+
+{{{
+python manage.py reset myapp
+
+You have requested a database reset.
+This will IRREVERSIBLY DESTROY any data for
+the "myapp" application in the database "mydb".
+Are you sure you want to do this?
+
+Type 'yes' to continue, or 'no' to cancel: yes
+}}}
+
+Now we have clean DB, lets populate it with our sample data:
+
+{{{
+python manage.py syncdb
+Loading 'initial_data' fixtures...
+Installing json fixture 'initial_data' from '/path/to/myapp/fixtures/'.
+Installed 24 object(s) from 1 fixture(s)
+}}}
