Django Admin Sortable 2 Not Saving Order

Question

I have installed Django Admin Sortable 2 in to my Django project. I can see the drag and drop order system in the admin but when I move around some objects the order doesn't get saved. I cannot see any error in my terminal log either when moving objects around.

Here is my Model and Admin python files. Do I need to do anything extra to get the order to save?

Model.py

class QuickLink(models.Model):
    title = models.CharField(max_length=20)
    image = models.FileField(null=True, blank=False,upload_to='media/quick_links')
    link = models.CharField(max_length=200)
    order = models.PositiveIntegerField(default=0, blank=False, null=False)

    def __str__(self):
        return self.title

    class Meta(object):
        ordering = ['order']

Admin.py

from django.contrib import admin
from adminsortable2.admin import SortableAdminMixin
from .models import QuickLink

@admin.register(QuickLink)
class QuickLinksAdmin(SortableAdminMixin, admin.ModelAdmin):
    pass

My versions are as follows:

Django 2.0.4

Python 3.6.1

Django Admin Sortable 2 0.6.19

Answer 1

Try running management command: ./manage.py reorder <app.model>

Answer 2

The reason I was having problems re-ordering the objects was I had already created the objects when then adding the Sortable functionality.

When setting a default for this as 0 it would set them all for 0. By going back and either recreating the objects or editing the field in the DB to the correct order I was able to fix this.
