Hi,

Problem was in my code I was using the request.POST['username'] instead of
request.POST.get('username')

You have given the solutions and the same I have implemented.

Once again thanks to you if any issues let you know.

*Actually, I am very new in Django hardly 1 week back started. This is my
first project to start for the learning purpose and I try to implement a
document management system with the workflow approval process.  I need your
support and help while developing the application. Once the design part
completed will share with you.*

def login_view(request):
templates = 'welcome.html'
username = request.POST.get('username')
password = request.POST.get('pass')
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
return render(request, templates ,{'user' : user  })
else:
#return redirect('welcome.html')
messages.error(request, 'Login Failed! Invalid username and password.')
return render(request, 'login.html',{'user' : user  })

Hey Vishal,

I don't think this error comes for what you told. The error raises for
which I v mentioned above.

And I agree with u as that is also have to do. As he did import auth so
need to write auto.authentication.

Re: dlango MultiValueDictKeyError

2019-08-05 Thread vishal singh

 //users = authenticate(request, username=username, password=password)

you have to use Auth keyword to remove this exception as right now it is
treated as a dict.

 users = Auth.authenticate(request, username=username, password=password)

Re: dlango MultiValueDictKeyError

2019-08-05 Thread Sipum Mishra

Hey Ajit,

This error comes when You are trying to get username, passwords from the
form.
It is due to the below reason -

In Login,
You are using -> request.POST['username'] which will raise a KeyError
exception if 'username' is not in request.POST.

Instead use -> request.POST.get('username') which will return None if '
username' is not in request.POST.

Additionally, .get allows you to provide an additional parameter of a
default value which is returned if the key is not in the dictionary.

For example, request.POST.get('username', 'mydefaultvalue')

Hope this helps. If any concern then let us know.
