Render in django can't passing an argument - django

Question

i'm new in django and i'm trying to create an application that user can change his/her password based on his/her id. So far is good, but when i'm trying to passing an argument from my views.py, there is a trouble that an argument can't passing to the html template.
This is my views:
def tambah_user(request, template_name='form_user.html'):
if 'username' in request.session:
username = User.objects.all()
data = {}
data['object_list'] = username
if request.method == 'POST':
user_form = UserForm(data=request.POST)
profile_form = UserProfileForm(data=request.POST)
if user_form.is_valid() and profile_form.is_valid():
user = user_form.save()
user.set_password(user.password)
user.save()
profile = profile_form.save(commit=False)
profile.user = user
profile.save()
return redirect('manajemen_user')
else:
print user_form.errors, profile_form.errors
else:
user_form = UserForm()
profile_form = UserProfileForm()
return render(request, template_name,
{'user_form': user_form, 'profile_form': profile_form, 'data': data},)
else:
return HttpResponseRedirect('/simofa/login')
with that code, data can't passing to the html template.
when i changed render like this
return render(request, template_name,data)
it works properly, but user_form and profile_form isn't passing to the template.
My question:
Can i passing data, user_form, profile_form together to the template?
if can, how? if not, is there any other way ?
I really appreciate your input. so please help me. Thanks ^__^

The render statement isn't expecting a trailing comma like when you're defining a tuple, which is most likely what's causing the error, however your code could use some refactoring....
from django.contrib.auth.decorators import login_required
from django.contrib.auth.models import User
from django.core.urlresolvers import reverse
from django.http import HttpResponseRedirect
# assuming you're using your own form here for some reason...
from .forms import UserForm
# use the login_required decorator instead of manually checking for the session
#login_required
def tambah_user(request, template_name='form_user.html'):
# `users` just makes more sense here for the variable name
users = User.objects.all()
# no need for the extra if clause to create unbound forms
user_form = UserForm(request.POST or None)
profile_form = UserProfileForm(request.POST or None)
if request.method == 'POST':
if user_form.is_valid() and profile_form.is_valid():
user = user_form.save()
# you need to pass in the raw password here,
# otherwise you're hashing the already hashed password
# if you were to be editing an instance
user.set_password(user_form.cleaned_data('password'))
user.save()
profile = profile_form.save(commit=False)
profile.user = user
profile.save()
# you need to use reverse by name to do this
return redirect(reverse('manajemen_user'))
else:
print user_form.errors, profile_form.errors
# notice I have omitted the trailing comma after the context
# dictionary
return render(request, template_name, {'user_form': user_form,
'profile_form': profile_form, 'data': users})
I hope you've read the documentation for authentication in Django, because there are built-in forms and views to do pretty much everything you'd ever need to do for users instead of writing your own.
