Editing a userprofile on django - django

Question

How to create a userprofile editable page and upon clicking submission it updates the details provided during registration(the details stored in the database) using DJANGO?.
Creation of registration form for a user, and like i have said in my opening post, i want the user after he must have logged in to able to edit what he provided during registration and it will update the previous details stored in the database.
I know i need to create a view for it, but have not arrived at how to call on the details provided during registration. Well maybe using user.get_profile()
forms.py
from django import forms
from django.contrib.auth.models import User
from django.forms import ModelForm
from registeredmember.models import Registeredmember
class RegistrationForm(ModelForm):
first_name = forms.CharField(label=(u'First Name'))
middle_name = forms.CharField(label=(u'Middle Name'))
last_name = forms.CharField(label=(u'Last Name'))
occupation = forms.CharField(label=(u'Occupation'))
income = forms.IntegerField(label=(u'Income Amount'))
age = forms.IntegerField(label=(u'Age'))
address_line1 = forms.CharField(label=(u'Address line 1'))
address_line2 = forms.CharField(label=(u'Address line 2'))
city = forms.CharField(label=(u'City'))
state = forms.CharField(label=(u'State'))
phone_no_Mobile = forms.IntegerField(label=(u'Phone Number (Home)'))
phone_no_Work = forms.IntegerField(label=(u'Phone Number (Work)'))
purpose = forms.CharField(label=(u'Purpose'))
username = forms.CharField(label=(u'Username'))
email = forms.EmailField(label=(u'Email Address'))
password = forms.CharField(label=(u'Password'), widget=forms.PasswordInput)
password1 = forms.CharField(label=(u'Verify Password'), widget=forms.PasswordInput)
class Meta:
model = Registeredmember
exclude = ('user','reference_number',)
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_email(self):
email = self.cleaned_data['email']
try:
User.objects.get(email=email)
except User.DoesNotExist:
return email
raise forms.ValidationError('That email address is already in the database, please provide another.')
class LoginForm(forms.Form):
username = forms.CharField(label=(u'Username'),widget=forms.TextInput(attrs={'size': '30'}))
password = forms.CharField(label=(u'Password'), widget=forms.PasswordInput)

def LoginRequest(request):

if request.method =='POST':
form = LoginForm(request.POST)
if form.is_valid():

password = form.cleaned_data['password']
registeredmember = authenticate(username=username, password=password)
if registeredmember is not None:
login(request, registeredmember)
return HttpResponseRedirect('/profile/')
else:
return render_to_response('carloan/loginerror.html', context_instance=RequestContext(request))
else:
'''user is submitting a blank login form, notify him that he submitted a blank form'''
return render_to_response('carloan/loginblank.html', context_instance=RequestContext(request))
else:
'''user is not submitting the form, show the login form'''
form = LoginForm()

def LogoutRequest(request):
logout(request)
return render_to_response('carloan/logout.html', context_instance=RequestContext(request))
The code below gives the error username already exists, but when i specify a new username it updates although it doesn't update the username but the other fields
views.py for the editprofile
#login_required
def editprofile(request):
registeredmember = request.user.get_profile()
if request.method == 'POST':
userprofile_edit = RegistrationForm(request.POST, instance = registeredmember)
if userprofile_edit.is_valid():
userprofile_edit.save()
return HttpResponseRedirect('/profile/')
else:
userprofile_edit = RegistrationForm(instance = registeredmember)
return render_to_response('carloan/editprofile.html', {'userprofile_edit': userprofile_edit}, context_instance=RequestContext(request))
Got it sorted out with codes below:
forms.py
class EditForm(forms.ModelForm):
class Meta:
model = Registeredmember
exclude = ('user','username','email','password','password1',)
views.py
#login_required
def editprofile(request):
if request.method == 'POST':
userprofile_edit = EditForm(request.POST, instance = request.user.get_profile())
if userprofile_edit.is_valid():
userprofile_edit.save()
return HttpResponseRedirect('/profile/')
else:
userprofile_edit = EditForm(instance = request.user.get_profile())
return render_to_response('carloan/editprofile.html', {'userprofile_edit': userprofile_edit}, context_instance=RequestContext(request))
Thank you all...

Django 1.5 and custom user models will help with this, but in the mean time your ModelForm set up is fine.
To initialize a ModelForm from an instance of its object, do this:
user_profile_form = RegistrationForm(request.POST, instance=request.user.get_profile())
The request.POST in that line allows you to update the user_profile_form object with the user's input. It will nicely merge the existing data from your instance with the new info from the user.
You can then print this to a view, or you can save it doing this:
if user_profile_form.is_valid():
user_profile_form.save()
else
# do other stuff
