How to check a boolean attribute in an if else statement?

Question

I have a user model with a column superuser:boolean. I also using a navigationbar where I want to to have three different views according to those conditions:

When someone is not signed in
When someone is signed in as a user

When someone is signed is as a user and the boolean value for superuser is true

<% if (user_signed_in? && user.super_user?) %>

<% elsif (user_signed_in?) %>

<% else %>

I am getting the error: "undefined local variable or method `user'"

How can I check if the column super_user of an user is true or false?

1) It looks like you're using Devise gem (because of user_signed_in?). In this case it is a current_user helper you're looking for, not user.

2) You do not need ? in here current_user.super_user - column is called super_user, not super_user?.

<% if (user_signed_in? && current_user.super_user) %>

<% elsif (user_signed_in?) %>

<% else %>
