Django User's Sessions getting Mixed.

In Django's admin interface, there is a form, of a specific model that I want to be rendered in different ways depending if the logged user accessing this form is a normal user or an admin. It's working find except one HUGE thing: it get's mixed. For instance, the fields that should be editable by the admin are read-only, after I immediately prior to that had been logged in as a "normal" user. If I try the exactly same thing immediately after restarting the server, works fine and all fields are editable. I guess that somehow the user's sessions are get mixed up. How to handle this?

Here is waht I have:

In the App's admin.py:

151 class AdminForm(ModelForm):
152     class Meta:
153         model = PromotionalSlot
154         exclude = ['deal']
155 
156 class NormalUserForm(ModelForm):
157     class Meta:
158         model = PromotionalSlot
159         exclude = ['site']
160         
161 class PromotionalSlotAdmin(admin.ModelAdmin):
162      def get_form(self, request, obj=None, **kwargs):
163         if request.user.is_superuser:
164             return AdminForm
165         else:
166             self.readonly_fields = ['start_date','end_date','level','city','status']
167             return NormalUserForm· 
168
169 admin.site.register(models.PromotionalSlot, PromotionalSlotAdmin)

Thanks

The problem is that your solution isn't thread safe. Django keeps the admin instance around and so the value you set to self.readonly_fields is used also for all subsequent requests in the thread. This is how you can make it thread safe:

class PromotionalSlotAdmin(admin.ModelAdmin):

    def get_readonly_fields(self, request, obj=None):
        if request.user.is_superuser:
            return []
        else:
            return ['start_date', 'end_date', 'level', 'city', 'status']

    def get_form(self, request, obj=None, **kwargs):
        if request.user.is_superuser:
            return AdminForm
        else:
            return NormalUserForm
