Re: Why does Django say my login form is invalid? How can I find out why Django thinks it is?

My `forms.py` looks like this. (I want user's email to be their login username.

class LoginForm(AuthenticationForm):
 username
= forms.EmailField(label=_("Email"), max_length=254)


 
class Meta:
 model
= User
 fields
= ("username",)

`views.py`:
def login_register(request, template="pages/login_register.html"):
 
if request.method=="POST":
  login_form
= LoginForm(request.POST)
  
if login_form.is_valid():
   
print "Login form valid"
   
return redirect(home_slug())
  # else:
  #  print "Login invalid"
 
else:
  login_form
= LoginForm()
 
return render(request, template, {"login_form": login_form})


`login_register.html`:
 <form method="post">
  {% csrf_token %}
  {{ login_form.as_p }}
  
<button type="submit">Log in</button>
 
</form>

The login form accepts two fields labeled "Email" and "Password." But when I hit "Log in" button, the page just seems to refresh. If I uncomment the `print` statement, it prints, indicating that `login_form.is_valid()!=True`. Why does Django do this?
