Not able to post form data to action url

I have a login form. After pressing the login button the the post data is sent to the view login_auth that authenticates the user data and redirects accordingly. However,after pressing the login button, I am not being redirected to the appropriate page.

views.py

def login_successful(request):
return render(request,"login_successful.html")

def login_invalid(request):
return render(request,"login_invalid.html")


def login(request):
return render(request,'login.html',c)

def loginauth(request):
username=request.POST.get("username",'')
password=request.POST.get("password",'')
user=auth.authenticate(username=username,password=password)
if user is not none:
user.login(request.user)
return redirect(login_successful)
else:
return redirect(login_invalid)


urls.py

urlpatterns = [
url(r'^registration/',views.registration),
url(r'^registration_successful/',views.registration_successful),
url(r'^home/',views.home),
url(r'^login/',views.login),

url(r'^login_successful/',views.login_successful),
url(r'^login_invalid/',views.login_invalid),
url(r'^login/auth',views.loginauth)
]


login.html

<html>
<form action="/login/auth" method="POST">{% csrf_token %}

Username :<input type="textbox" name="username" >
Password :<input type="password" name="password">
<input type="submit" value="Login">

</form>
</html>

Answer

Your login url pattern is missing a trailing $. It should be:

url(r'^login/$', views.login),

Without the dollar, the /login/auth is matched by r'^login/, so the request is handled by your login view.

It's a bit unusual to process the form on a different url. Django comes with authentication views, including a login view. I would recommend using this rather than writing your own.
