RoR: I'm having trouble doing a simple link to an action

Question

I am trying to link to action addData in the entries controller. I have constructed the link like this:

<%= link_to image_tag (w.link, :border =>0) ,:controller => :entries, :action  =>  :addData %>

but when I click on the link, I get this error:

Couldn't find Entry with ID=addData

I'm pretty sure this is because I have a restful design. Is there a way around this problem? Thanks for reading.

Answer 1

Have you defined the route properly for this action addData? By the way try this :

<%= link_to image_tag (w.link, :border =>0) ,{:controller => :entries, :action  =>  :addData} %>

Answer 2

Rails has migrated wholly to a RESTful design. This means that in order to use non standard actions you have to add them to your resources in config/routes.rb.

If they operate on all resources you add them to the hash :collection => {:addData => :post} In case you have one operating on a single resource with an id use :member. To some it up for you.

map.resources :entries, :collection => {:addData => :post}

To use the old style of mapping any action to any controller you can add the following two lines to your config/routes.rb

  map.connect ':controller/:action/:id.:format'
  map.connect ':controller/:action/:id'
