Question

So I just got my first django app deployed.

I did a syncdb and created my superuser account for the site.

Now when I access the page and press the login button I get this error. I think it has something to do with the password but I’m not sure.

ValueError at /accounts/login/
too many values to unpack

I’m using the generic login view

(r'^accounts/login/$', login, {'template_name': 'authentication/login.html'}),

The following is the traceback

Exception Type: ValueError at /accounts/login/
Exception Value: too many values to unpack

Answer 1

Yes, there is a problem in the password.

The error is in the way the password has been encrypted and stored in the DB. It can be clearly seen from the statement algo, salt, hsh = enc_password.split('$') in the traceback. The encrypted password splitting returns more than 3 values.

So, please have look at the password encryption schemes and related.
