Question

I am trying to follow the [Django Tutorial 6][1] to do the user authenication. But i get stuck. I am getting this Attribute error: unicode’ object has no attribute ‘get’. The models,view and forms are provided below. Not sure where the error is… Need some help…

models.py

from django.db import models
from django.contrib.auth.models import User

class Drinker(models.Model):

    user = models.OneToOneField(User)
    birthday = models.DateField()
    name = models.CharField(max_length=100)

    def __unicode__(self):
        return self.name

views.py

from django.http import HttpResponseRedirect
from django.shortcuts import render_to_response
from django.template import RequestContext
from drinker.forms import RegistrationForm
from django.contrib.auth.models import User
from drinker.models import Drinker


def DrinkerRegistration(request):
    if request.POST:
        form =RegistrationForm(request.POST)
        if form.is_valid():
            user = User.objects.create_user(username=form.cleaned_data['username'],email=form.cleaned_data['email'])
            password = form.cleaned_data['password']
            user.save()
            drinker=Drinker(user=user,name=form.cleaned_data['name'],birthday=form.cleaned_data['birthday'])
            drinker.save()
            return HttpResponseRedirect('/profile/')
        else:
            return render_to_response('register.html',{'form':form,},context_instance=RequestContext(request))
    else:
        form = RegistrationForm()
        return render_to_response('register.html',{'form':form,},context_instance=RequestContext(request))

forms.py

from django import forms
from django.contrib.auth.models import User
from django.forms import ModelForm
from drinker.models import Drinker 

class RegistrationForm(ModelForm):
    username = forms.CharField(label=(u'User Name'))
    email = forms.EmailField(label =(u'Email Address'))
    password = forms.CharField(label =(u'Password'),widget=forms.PasswordInput(render_value=False))
    password1 = forms.CharField(label =(u'Verify Password'),widget=forms.PasswordInput(render_value=False))

    class Meta:
        model = Drinker
        exclude = ('user',)

    def clean_username(self):
        username = self.cleaned_data['username']
        try:
            User.objects.get(username=username)
        except User.DoesNotExist:
            return username
        raise forms.ValidationError("That username is already taken. Please select another")
    def clean(self):
        password = self.cleaned_data['password']
        password1= self.cleaned_data['password1']
        if password and password1 and password != password1:
            raise forms.ValidationError("The passwords did not match. Please try again")
        return password

Answer 1

You’re returning password from the clean() method, rather than self.cleaned_data.
