Update to this post: "show" action for this category has been done. I think this is one among the CRUD pages. (create, read, update, delete) I guess, show => read The following pages are created/modified for this "show" action for "category" controller: ------------------------------------------------------------------------------ app/controller/category_controller.rb ( added show def to this file) app/views/category/show.erb (new template created. this is a new file) ################## app/controller/category_controller.rb ########### def show @category=Category.find(params[:category_id]) end ####################################################################### ################### view ########################################## /app/views/category# more show.erb <h1><%= @category.category_title %></h1> <p><strong>Title: </strong> $<%= @category.category_title %><br /> <strong>Short_Description :</strong> <%= @category.category_short_desc %><br /> <strong>Long_Description :</strong> <%= @category.category_long_desc %><br /> <strong>Status :</strong> <%= @category.status%><br /> <strong>Created Date:</strong> <%= @category.dt_created %><br /> <strong>Modified Date:</strong> <%= @category.dt_modified %><br /> <strong>Created User:</strong> <%= @category.user_created %><br /> <strong>Modified User:</strong> <%= @category.user_modified %><br /> </p> <p><%= @category.category_title %></p> <hr /> <%= link_to 'Back', {:action => 'list'} %> ################.################################# Summary: ----------------- To create the "show" action, controller file was modified and a new view template was created. Model remains inchanged. So, this works! The link created in the abover list.erb, shows this show.erb page when clicked. The link works and that means the "show" action is working. ------------------------ Please let me know if I'm missing any in this route. Just thought of updating this here, as this inspires me to move forward, thinking i have people here to discuss with. that makes all the big difference. I will keep you all posted. - thanks again, radha. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
