Django无法设置内置/扩展类型'object'的属性

Question

Can anyone see the issues with this?

def is_valid(self, bundle, request=None):

    errors = {}
    # Check if user already exists before allowing API to create a new one.
    this_email = bundle.data.get('email', None)
    object.count = MemberParticipant.objects.filter(email=this_email).count()
    if object.count != 0:
         errors['Login']='Duplicate email address! A  participant with the ' \
                         'email address %s already exists.' % this_email
    return errors

I'm getting the following error:

can't set attributes of built-in/extension type 'object'

I'm using a Tastypie's custom validator

Are you trying to use object.count as a single variable name? You can't mix dots into identifiers in Python without triggering attribute resolution - use something like object_count instead. As written you're trying to reassign the count attribute of the built in object class.
