Hi everyone,
I have a problem. I want to display a different select box wether the
current user is an admin or an user.
So I thought I could do this in my view where my form is displayed :
<p class="form-input">
<%= f.label(:role_id, ''Role:'') %>
<%
if (current_user.admin?)
then collection_select(:user, :role_id, Role.find(:all, :order =>
"name desc"), :id, :name)
else # Here I would code an another collection_select
end
%>
</p>
But It doesn''t work. Nothing is displayed!
Could you help me?
Thanks!

I would do 2 things to try to fix your problem if I were you: 1. Make sure you know the type of user you have when you get the request for the page 2. Put the logic of generating the data in the controller, then use an instance variable to display the values and forget the ''if then else'' logic in the view. Your view will be much easier to read and modify. My guess is that the problem you have is that you don''t have a current_user type value (or not the one you believe you have) by the time your code runs.
