With the I(virtualenv) parameter, all management commands will be executed by the given I(virtualenv) installation. version_added: "1.1" options: command: choices: [ 'cleanup', 'flush', 'loaddata', 'runfcgi', 'syncdb', 'test', 'validate' ] description: - The name of the Django management command to run. Allowed commands are cleanup, createcachetable, flush, loaddata, syncdb, test, validate. required: true app_path: description: - The path to the root of the Django application where B(manage.py) lives. required: true settings: description: - The Python path to the application's settings module, such as 'myapp.settings'. required: false pythonpath: description: - A directory to add to the Python path. Typically used to include the settings module if it is located external to the application directory. required: false virtualenv: description: - An optional path to a I(virtualenv) installation to use while running the manage application. required: false apps: description: - A list of space-delimited apps to target. Used by the 'test' command. required: false cache_table: description: - The name of the table used for database-backed caching. Used by the 'createcachetable' command. required: false database: description: - The database to target. Used by the 'createcachetable', 'flush', 'loaddata', and 'syncdb' commands. required: false failfast: description: - Fail the command immediately if a test fails. Used by the 'test' command. required: false default: "no" choices: [ "yes", "no" ] fixtures: description: - A space-delimited list of fixture file names to load in the database. B(Required) by the 'loaddata' command. required: false notes: - U(http://www.virtualenv.org/, virtualenv) must be installed on the remote host if the virtualenv parameter is specified. - This module will create a virtualenv if the virtualenv parameter is specified and a virtualenv does not already exist at the given location. - This module assumes English error messages for the 'createcachetable' command to detect table existence, unfortunately. requirements: [ "virtualenv", "django" ] author: Scott Anderson ''' EXAMPLES = """ #
