will_paginate in the same page for the same instance variable but for three different displays

Question

This is the controller I have writter for Orders.

 def index
    if current_user.has_role? :admin
      @orders = Order.all.paginate(:page => params[:page], :per_page => 5)
    elsif current_user.has_role? :customer
      @orders = Order.where(:email => current_user.email).paginate(:page => params[:page], :per_page => 5)
    elsif current_user.has_role? :white_label
      @orders = Order.where(:performer_id => (Performer.where(:white_label_id => current_user.white_label.id))).paginate(:page => params[:page], :per_page => 5)
    else
      @orders = current_user.performer.orders.paginate(:page => params[:page], :per_page => 5)
    end
    @custom_video = CustomVideo.new
  end

As you see I have used will_paginate gem to do pagination. This is the view page where I am doing pagination.

<div class="container">
  <div class="span 8">
            <% if current_user.has_role? :admin %>
            <%role =1%>
          <%elsif current_user.has_role? :performer %>
            <%role =2%>
          <% else %>
            <%role =3%>          
          <% end %>

The problem in this is that. If I click the second page for the first table, it is going to the second for the next table too. I have tried giving the :param_name => 'questions_page' suggested here. But the trouble here is that, I am not using different instance variable for the tables but the same one. How do I solve this?>

Answer 1

You've almost answered your own question. You need to be using separate instance variables for each table if you want them to behave separately.
