class Theme(models.Model):
   name=models.CharField(max_l         


        

Answer 1

I actually prefer to do it in get_form like so:

class CompanyAdmin(admin.ModelAdmin):
    def get_form(self, request, obj=None, **kwargs):
        form = super(CompanyAdmin, self).get_form(request, obj, **kwargs)
        form.fields['theme'].queryset = Theme.objects.filter(name__iexact='company')
        return form
