PASSWORD_HASHERS setting in Django

Question

i have an error when ever i try to login by any User error

Unknown password hashing algorithm \'sahar\'. Did you specify it in the PASSWORD_HASHERS

Answer 1

It means there is a plain text 'sahar' stored as the password of the account of a user who tries to log in.
Update the password of the user in Admin or in manage.py shell

user = User.objects.get(username=username)

# use set_password method
user.set_password('sahar')
user.save()

# INSTEAD OF 
user.password = 'sahar'
user.save()

Also check your other views to correct the user.password = '...' and User.objects.create(password='...') usages.

Answer 2

This is the best way to save log in details you can create an object from the form as

user = form.save(commit=False)

then clean the data to remove any scripts entered in the form fields.

username = form.cleaned_data['username']
password = form.cleaned_data['password']
user.set_password(password)
user.save()
