Hi…

I have list.rhtml file default generated by scaffold for user table.
This file displays list of all user table rows. Inside this file I want
to display the list of the all the rows from my anothe table (stores).
How to do that?
I tried with following inside my above list.rhtml.

<% for store in @stores %>

<% for column in Store.content_columns %> <%=h store.send(column.name) %> <% end %> <% end %> ==================

But its giving me error like:-

===============
You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.each

I think I am getting above error because list.rhtml file is in user view
& not in store view . How to fix above error ?

You need to populate the @stores variable before using it. If you look
in UserController#list you’ll see how @users is populated.

If you go to the UserController#list method, add

@stores = Store.find(:all)

Variables are created in the controller and then accessed in the view.
