I am facing an error from this Django project. I have tried all the advice i can come across still its not working properly. Below is the error from the web.

CodePudding user response：

As error message clearly says, you have to encode the password first.

In main/views.py on line 171 you have

hashed = bcrypt.hashpw(request.POST['login_password'], bcrypt.gensalt())

Your request.POST data is a string, so you should encode it to bytes:

hashed = bcrypt.hashpw(request.POST['login_password'].encode(), bcrypt.gensalt())

You can select other encoding (not default utf8) with .encode('ascii') (choose one and don't change it later, utf8 is probably the best choice in general).
