Implementing the login functionality

Having implemented signup and logout, let's now implement login:

1. Create a login path in /accounts/urls.py:

   …
   urlpatterns = [        
       path('signupaccount/', views.signupaccount,
         name='signupaccount'),
       path('logout/', views.logoutaccount, 
         name='logoutaccount'),
       path('login/', views.loginaccount, 
         name='loginaccount'),
   ]

2. In /accounts/views.py, implement loginaccount with the following in bold:

   …
   ...
   from django.contrib.auth.models import User
   from django.contrib.auth.forms import
     AuthenticationForm
   from django.contrib.auth import login, logout,
      authenticate
   ...
   def loginaccount(request):    
    ...
