login() missing 1 required positional argument: 'user'

Question

Here is my view,

def login_view(request) :
    if request.method == 'POST':
        form = LoginForm(request.POST)
        if form.is_valid():
          email = form.cleaned_data['email']
          password = form.cleaned_data['password']
          user = authenticate(email=email, password=password)

          if user is not None:
              form = LoginForm()
              login(request, user)

I get an error:

login() missing 1 required positional argument: 'user'

Also, I am using a custom user model

My urls.py:

urlpatterns = [
path('',views.register, name='register' ),
path('form',views.form, name = 'form'),
path('login',views.login, name = 'login ')]

You probably overwrote `login` somewhere with another function. — Willem Van Onsem, Jul 26 '18 at 14:30

You're not using the right view, try this instead

path('login',views.login_view, name = 'login ')

from django.urls import path, include
from django.contrib.auth import views

urlpatterns = [
path('',views.register, name='register' ),
path('form',views.form, name = 'form'),
path('login/', views.login, {'template_name': 'login.html'}, name='login'),
]

or

from django.urls import path, include
from django.contrib.auth import views as auth_views

urlpatterns = [
path('',views.register, name='register' ),
path('form',views.form, name = 'form'),
path('login/', auth_views.login, {'template_name': 'login.html'}, name='login'),
]

If you are using django's own authentication scheme, the second example will be more accurate.

I actually changed the login path in the url file. I think the error is due to the path connection. that's path =>

path('login',views.login, name = 'login ')]

This answer is confusing. Could you give OP more insights on what is the purpose of your solution ? — scharette, Jul 26 '18 at 14:41

Django built in user authentication only accepts username and password to login. You have to change it if you want to log in your user by email and password.

You declared your function as login_view in views.py but you are calling it as login on urls.py. Try view.login_view.

In your code, it seems that you have a function named login_view defined, but in your URL configuration, you are referring to a function named login. This mismatch in function names is likely causing the error.

Change the function name in your URL configuration to match the view function name,

urlpatterns = [
    # other URL patterns
    path('login', views.login_view, name='login'),
]

login() missing 1 required positional argument: 'user'
