Question

I have a users table. It contains a field “user_type”.
I added the following scope stmts to the user.rb file:

scope :uemployee, where(:user_type => 'employee')
scope :uclient, where(:user_type => 'client')
scope :ucontractor, where(:user_type => 'contractor')

I created a view and I would like it to list he employees.
Here is the code I’m trying to use:

 <% @users.uemployee.each do |user| %>

But, I get “undefined method `uemployee’ for nil:NilClass”

What am I doing wrong?

Thanks

Looks like you wanted to do this:

<% User.uemployee.each do |user| %>

But this is considered to be a bad practice. You have to prepare you data in a controller and a view just cycles through it:

# in a controller's action
@users = User.uemployee

#in a view
<% @users.uemployee.each do |user| %>

But even this isn’t the best approach. If you create the file views/users/_user.html.erb which shows the info about a particular user (current user will be available as a simple user variable, without the @) then you can simply write:

# in a view
<%= render @users %>
# remember, @users variable was set in your controller

then Rails will cycle through all the users “inside” the @users variable and show them one-by-one.
