Method wont define!

Hey everyone,

I am getting a very frustrating "no method define" error when I try to include an .erb tag in my 'status index' page. I cannot understand how the user is STILL undefined if the users "first & last' name is shown correctly on the 'status show' page.

I have read all the documentation i can find regarding strong params and devise on rails 4 so I think i must be missing something simple.

Any help would be much appreciated!

Thanks

Ok I worked it out! (i hope)

I needed to remove the @ in the index page. Everything works well now, however, I don't fully understand why, can anyone help me with this?

What is the significance of the @ in this situation? why is it used in the 'show' page and not in the 'index' page?

Thanks!

the @ symbol is used to indicate an instance variable; this kind of variables can be defined in the controller and they can be accessible from the view.

Without the @ symbol the variable must be defined in the same view.
