*First*: you should not use *params *method in your views, it is only available in a controller as a Hash to get values from views. *Second*: you should just use a symbol to indicated the key to are going to pass from the view to the controller; I mean do not use *:employee.id* but *:employee_id*. *Third*: as for Rails 2.3.8 API <http://api.rubyonrails.org/v2.3.8/>, you can specify link_to as follows: <%= link_to "#{t('retrieve_case')}", {:controller => 'employee_indisciplines', :action => 'show_indisciplines', :employee_id => retrieve_case, { :class => 'submit_button' }, :method => 'post' %> You should replace retrieve_case by the appropriate value that is available in the veiw. In your controller you will get this value from the 'params hash: patams[:employee_id] Fourth: do not forget to change the routes (routes.rb file) to enable the called controller action. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
