Hey Ian, You’re inpsect is telling us that @retrieve_case isn’t populated. You are populating that directly from the params, are there ids being passed in on the URL? The problem you have now is from before you render this view/controller.

You may want to do @retrieve_case directly. The link_to should be able to stringify the object for you. - Adam On Mon, Aug 11, 2014 at 10:06 PM, Ian Baraza Brayoni <[email protected]> wrote: Hi Cynthia/Kaufman, Thank you for your response. I have edited my gist and it looks like, this line: <%= link_to "Retrieve Case", {:controller => 'employee_indisciplines', :action => 'show_indisciplines', :employee_id => @retrieve_case.inspect }, { :class => 'submit_button' }, :method => 'post' %> is receiving a nil id after doing an inspect on it( I have shared my development logs in the gist). 1 2 3 4 5 6 7 Processing EmployeeIndisciplinesController#show_indisciplines (for 127.0.0.1 at 2014-08-12 07:27:35) [GET] Parameters: {"action"=>"show_indisciplines", "employee_id"=>"nil", "controller"=>"employee_indisciplines"} as a result, the following section in my rendered html is iterating on a nil object hence nothing is displayed. <% @employee_indiscipline.each do |employee | %> <tr class="tr-<%= cycle('odd', 'even') %>"> <td class="col-4"><%= employee.content %></td> <td class="col-7"><%= employee.created_at.strftime("%A, %d. %B %Y, %H:%M") %></td> </tr> <% end %> Regards, Ian Brayoni On Tue, Aug 12, 2014 at 1:52 AM, Rob Kaufman <[email protected]> wrote: Ian, From reading your gist, I think you’re talking about the link_to on line 17 of “_list_indisciplines.html.erb”. You’ve got a period in your params employee.id is not valid (you’re setting to the id (4), not to the symbol itself). Also, params[:retrieve_case[]] means that you’re getting [] every time. <%= link_to "#{t('retrieve_case')}", {:controller => 'employee_indisciplines', :action => 'show_indisciplines', :employee.id => params[:retrieve_case[]]}, { :class => 'submit_button' }, :method => 'post' %> On August 11, 2014 at 8:57:34 , Cynthia Kiser ([email protected]) wrote: You asked about passing parameters so, in addition to the code generating the link, I need to see the link that it creates and how the routing system interprets it. Please add the following 2 pieces of information to your gist: 1) the rendered html from _list_indisciplines.html.erb 2) the section of the development log when you click that link, e.g. Processing PagesController#show (for 131.215.229.27 at 2014-03-12 10:46:17) [GET] Parameters: {"action"=>"show", "url_parts"=>["protocols"], "controller"=>"pages"} And by the way, since you have map.feed, that should be creating a named route for you: feed_path. So if you want, you can use that instead of the hash explicitly listing controller and action. Use `rake routes` to see which of your routes have named route helper methods available.
