问题

I am writing an simple django application and got stuck into this error, can some one please help me my views.py looks exactly as

def custom_login(request):
    if request.user.is_authenticated():
        return HttpResponseRedirect('dashboards')        
    return login(request, 'login.html', authentication_form=LoginForm)

def custom_logout(request):
    return logout(request, next_page='/')

def user(request):
        context = {'user': user, 'groups': request.user.groups.all(), 'dashboards': Dashboard}
    return render_to_response('registration/dashboards.html', context, context_instance=RequestContext(request))

and my forms.py is like

from django import forms
from django.contrib.auth.models import User
from django.forms import ModelForm
#from mhawk.models import Dashboard


class LoginForm(forms.Form):
        username        = forms.CharField(label=(u'User Name'))
        password        = forms.CharField(label=(u'Password'), widget=forms.PasswordInput(render_value=False))

Edit

There is your problem, in urls, you are pointing not to a view, but to a User. Python is case sensitive, you know. :)

Your problem is instead of response, middleware is getting a User object, so somwhere, instead of response you are returning a user, I don't see it in your code though.

Regardless, why don't you use django's authentication views? They do same stuff as you are trying to implement.

from django.contrib.auth.views import login, logout

def custom_login(request):
    if request.user.is_authenticated():
        return HttpResponseRedirect('dashboards')        
    return login(request, 'login.html', authentication_form=LoginForm)

def custom_logout(request):
    return logout(request, next_page='/')

Oh yeah, and add this to your settings:

LOGIN_REDIRECT_URL = '/dashboards/'

And here is a promised user view:

from django.contrib.auth.decorators import login_required

@login_required
def user(request):
    # btw 'user' variable is already available in templates
    context = {'user': request.user}
    return render_to_response('dashboards.html', context, context_instance=RequestContext(request))
