Hi everyone,

I am running through the RailsSpace tutorial. I’m trying to figure out  
the advanced login section, which in short creates a cookie and an  
authorization token in the users table in the database.

My trouble is, I’m getting error: Wrong number of arguments (0 for 1)

the code that has been updated is as follows:

In ApplicationController:

before\_filter :check\_authorization

When I comment this line out, the application is displayed without  
error. Unfortunately i don’t know enough about rails to understand how  
to fix this. However without it, I can’t add the remember me  
functionality in the site…

Any ideas???

Many Thanks for reading.

What does you check\_authorization method look like ? What’s the  
backtrace when you get that error ?
