I work with django 1.8.7 and python 2.7 . I have peoblem with migrate. when I migrate my models , permission and contenttypes don’t create automatically. error looks like this:

    Traceback (most recent call last):

    for codename, _name in custom:
    ValueError: too many values to unpack

and when I change migrations file like this:

    # -*- coding: utf-8 -*-
    from __future__ import unicode_literals

    from django.contrib.auth.management import _get_builtin_permissions, _check_permission_clashing
    from django.db import migrations, models

    def _get_all_permissions(opts, ctype):
        """

        """
        builtin = _get_builtin_permissions(opts)
        custom = list(opts.permissions)

        if any(isinstance(el, basestring) for el in custom):
            custom = [custom]

        _check_permission_clashing(custom, builtin, ctype)
        return builtin + custom


    class Migration(migrations.Migration):

        dependencies = [
            migrations.swappable_dependency(settings.AUTH_USER_MODEL),
        ]

        operations = [
            migrations.CreateModel(
                name='JsonModel',
                fields=[

                    ('user', models.ForeignKey(to=settings.AUTH_USER_MODEL)),
                ],
                options={

        def forwards(self, orm):
            from django.contrib.auth import management
            management._get_all_permissions = _get_all_permissions

and run command ” python manage.py migrate ” this is responsed:

        Operations to perform:
    Apply all migrations: (none)
    Running migrations:
    No migrations to apply.
    Your models have changes that are not yet reflected in a migration, and so won't be applied.
    Run 'manage.py makemigrations' to make new migrations, and then re-run 'manage.py migrate' to apply them.

thanks for your help. :)

Answer

I find the solution, in other model.py apps when define custom permissions , my colleagues define custom permissions like this:

    class Meta:
    permissions = (
        ('view_log', 'Can view log'),
        ('view_failedloginlog', 'Can view failed login log'),
        ('view_loginlog', 'Can view login log'),
        ('view_loginattempt', 'Can view login attempt'),
        ('view_onlineusers', 'Can view online users')
    )

although, type of permission should be tupe; this means permission should be define like this:

    class Meta:
    permissions = (
        ('view_log', 'Can view log'),
        ('view_failedloginlog', 'Can view failed login log'),
        ('view_loginlog', 'Can view login log'),
        ('view_loginattempt', 'Can view login attempt'),
        ('view_onlineusers', 'Can view online users'),
    )

this “,” is so important!!! :))
