How can I update attributes with a link in Rails?

Question

I want to update attributes in a data table called "rang" from 0 to 1 using a link.

I have an action:

def ready
  @task = Task.find(params[:id])
  @task.update_attributes(:ready => '1')
  @task.save
  redirect_to :action => :index  
 end

And a link:

<%= link_to 'READY', { :action => :ready, :id => task.id } %>

But nothing happens. What am I doing wrong?

Answer 1

Try :

in routes.rb

  resources :tasks do
      member do
        get 'ready'
      end
    end

Then link like:

<%= link_to 'READY', ready_task_url(task.id) %>
