title: Object level permissions in Django admin
body: <p>I have a model which looks like this:</p>
  
  <pre><code>class Change(models.Model):
      RFC = models.CharField(max_length=10)
      Ticket_Number = models.CharField(max_length=10)
      Plan_Owner = models.ForeignKey(User)
  </code></pre>
  
  <p>I then register the model in the Django admin via this:</p>
  
  <pre><code>class ChangeAdmin(admin.ModelAdmin):
      search_fields = ('RFC', 'Ticket_Number','Plan_Owner')
      list_display = ('RFC', 'Ticket_Number','Plan_Owner')
  
      fieldsets = [
          ('Ticket Details', {
              'fields': ['RFC', 'Ticket_Number', 'Plan_Owner']}),
      ]
  
  admin.site.register(Change, ChangeAdmin)
  </code></pre>
  
  <p>What I want to achieve is to ensure that the Plan_owner for a particular change is the only one who can edit it apart from a superuser. Everyone can view it, but the plan owner is the only one who can make changes to it.Also by editing I mean, he can do ever thing but delete a row. I have had a look at Django guardian and it does exactly what I want but one has to manually set the permissions in guardian for each row. I am looking for a solution wherein these permissions are automatically set as per my requirements ...</p>
