Choose test database?

Question

I'm trying to run

./manage.py test

But it tells me

Got an error creating the test database: permission denied to create database

Obviously it doesn't have permission to create the database, but I'm on a shared server, so there's not much I can do about that. I can create a new database through the control panel but I don't think there's any way I can let Django do it automatically.

So, can't I create the test database manually and instead tell Django to flush it every time, rather than recreating the whole thing?

Answer 1

I had a similar issue. But I wanted Django to just bypass the creation of a test database for one of my instances (it is not a mirror tough). Following Mark's suggestion, I created a custom test runner, as follows

from django.test.simple import DjangoTestSuiteRunner


class ByPassableDBDjangoTestSuiteRunner(DjangoTestSuiteRunner):

    def setup_databases(self, **kwargs):
        from django.db import connections
        old_names = []
        mirrors = []

        for alias in connections:
            connection = connections[alias]
            # If the database is a test mirror, redirect its connection
            # instead of creating a test database.
            if connection.settings_dict['TEST_MIRROR']:
                mirrors.append((alias, connection))
                mirror_alias = connection.settings_dict['TEST_MIRROR']
                connections._connections[alias] = connections[mirror_alias]
            elif connection.settings_dict.get('BYPASS_CREATION','no') == 'no':
                old_names.append((connection, connection.settings_dict['NAME']))
                connection.creation.create_test_db(self.verbosity, autoclobber=not self.interactive)
        return old_names, mirrors

Then I created an extra dict entry in one of my databases entries inside settings.py, 'BYPASS_CREATION':'yes',

Finally, I configured a new TestRunner with

TEST_RUNNER = 'auth.data.runner.ByPassableDBDjangoTestSuiteRunner'
