How to load initial_data (fixture) after migration and not after syncdb?


I have a bootstrap script that performs syncdb and migrate:

import settings
from django.core.management import setup_environ, call_command

setup_environ(settings)                                         # Setting up the env settings
call_command('syncdb', migrate=True, interactive=False)         # Sync the database

Pre-Requisites:

  • django-south for migrations.

Process happening:

  • initial_data fixture contains data for a model that is created by migrations.
  • syncdb is executed it creates all the tables except for those apps where migrations exists.
  • Post syncdb it tries to load initial_data and raises error of db not found because the table for app with migrations were not created by syncdb. [ Problem ]
  • Then it performs migration which creates the db.
  • Post migration it automatically loads initial_data successfully this time.

Problem:

  • How can I get rid of the error, when it tries to load fixture for the table that is not yet created ?
  • Can I edit the above script in a way so that it loads initial_data only after performing the migration ?

Solution

  • You could disable loading initial data when syncdb:

    call_command('syncdb', load_initial_data=False, interactive=False)
    call_command('migrate', interactive=False)
    

    From the source code of syncdb.py:

    # Stealth option -- 'load_initial_data' is used by the testing setup                                                               
    # process to disable initial fixture loading.                                                                                      
    load_initial_data = options.get('load_initial_data', True)
