Thanks a lot! It works.
It even works with __getattr__, so i do not have to create a subclass
for
every model.

class MyForm(forms.ModelForm):
   def do_authorisation(self, name):
  print self.Meta.model._meta.verbose_name
  #raise forms.ValidationError('Error Message')
  return self.cleaned_data[name]

   def __getattr__(self, name):
  print name
  if name[:6] == 'clean_':
 return lambda: self.do_authorisation(name[6:])

Custom clean methods for admin site?

[krase]

Hi,

i am trying to build an authorisation system for the admin site.
The authorisation should not only be based on user, group and type of
the object, but also
on contents the user just typed in.
I assume that i have to override the clean() methods of the ModelAdmin
classes.

First i tried this:

class MyForm(forms.ModelForm):
   def clean(self):
  #do authorisation here
  return super(MyForm, self).clean()

class FooAdmin(admin.ModelAdmin):
   form = MyForm
   model = Foo

The Problem here is that i can not raise ValidationErrors for single
fields.

Then i found this: 
http://code.djangoproject.com/wiki/NewformsHOWTO#Q:HowdoIaddcustomvalidation
The second example of this question seems to be the right one, but i
don't understand how to
create a custom clean() method here.

A quick an dirty example is very appreciated ;)
