Django not accepting valid credentials - django

Question

views.py. My default user login template, I have tried both methods listed below and don't know where I am makeing a mistake - I get an error that my credentials are incorrect every time
def signup(request):
if request.method == 'POST':
form = SignUpForm(request.POST)
if form.is_valid():
user = form.save()
user.refresh_from_db() # load the profile instance created by the signal
user.profile.university = form.cleaned_data.get('university')
user.save()
raw_password = form.cleaned_data.get('password1')
user = authenticate(username=user.username, password=raw_password)
#user_login(request, user)
return redirect('main:main_page')
else:
form = SignUpForm()
return render(request, 'signup.html', {'form': form})
def user_login(request):
'''
Using different method for getting username, tried this and didn't work either
if request.method == 'POST':
form = AuthenticationForm(request, data=request.POST)
if form.is_valid():
username = form.cleaned_data.get('username')
password = form.cleaned_data.get('password')
user = authenticate(username=username, password=password)
if user is not None:
login(request,user)
messages.info(request, "Successfully signed in")
return redirect('main:home')
else:
message = 'Sorry, the username or password you entered is not valid please try again.'
return render(request, 'login.html', {'message':message})
else:
message = 'Invalid'
return render(request, 'login.html', {'message':message})

return render(request, 'login.html', {"form":form})

Forgot Password
</form>
I cannot figure out why my Django does not accept correct credentials. Which part of my code seems to be incorrect?

make sure to define the right user model to django settings, add
# AUTH_USER_MODEL = 'YOUR_APP_NAME.YOUR_CUSTOM_USER_MODEL'
to your django settings .like # AUTH_USER_MODEL = 'users.User'
and you need to write an abstract user model .
from django.contrib.auth.models import AbstractUser
class RightsSupport(models.Model):
class Meta:
managed = False # No database table creation or deletion \
# operations will be performed for this model.
permissions = (
("add_user", "Can Create User"),
("view_user", "Can View Single User"),
("change_user", "Can Change User"),
("list_user", "Can View User List"),
("add_plan", "Can Create Plan"),
("view_plan", "Can View Single Plan"),
("change_plan", "Can Change Plan"),
("list_plan", "Can View Plan List"),
)
class User(AbstractUser):
CREATED = 0
ACTIVE = 1
BANNED = 2
KICKED = 3
UPGRADE = 4
STS = (
(CREATED, 'Just Created'),
(ACTIVE, 'Activated'),
(BANNED, 'Disabled'),
(KICKED, 'Disabled'),
(UPGRADE, 'Active'),
)
status = models.IntegerField(choices=STS, default=CREATED, blank=True, null=True)
def __str__(self):
return self.username
also update your view, that code has a huge mistake on it . you forget to close docstring .
def signup(request):
if request.method == 'POST':
form = SignUpForm(request.POST)
if form.is_valid():
user = form.save()
user.refresh_from_db() # load the profile instance created by the signal
user.profile.university = form.cleaned_data.get('university')
user.save()
raw_password = form.cleaned_data.get('password1')
user = authenticate(username=user.username, password=raw_password)
#user_login(request, user)
return redirect('main:main_page')
else:
form = SignUpForm()
return render(request, 'signup.html', {'form': form})
def user_login(request):
'''
Using different method for getting username, tried this and didnt work either
'''
if request.method == 'POST':
form = AuthenticationForm(request, data=request.POST)
if form.is_valid():
username = form.cleaned_data.get('username')
password = form.cleaned_data.get('password')
user = authenticate(username=username, password=password)
if user is not None:
login(request,user)
messages.info(request, "Successfully signed in")
return redirect('main:home')
else:
message = 'Sorry, the username or password you entered is not valid please try again.'
return render(request, 'login.html', {'message':message})
else:
message = 'Invalid'
return render(request, 'login.html', {'message':message})
else:
form=AuthenticationForm()
return render(request, 'login.html', {"form":form})
