在Rails中进行RESTful删除后，有没有办法重定向到特定页面？

Question

Lets say I have a message resource. Somewhere in the html I have:

<%= link_to("Delete", message, :title => 'Delete', :confirm => 'Are you sure?', 
   :method => :delete )%> 

Right after I delete it, it redirects me to the page where it lists all the messages. Is there a way to redirect to a page that I specify after the deletion?

Answer 1

In the controller:

def delete
  Item.find(params[:id]).destroy
  redirect_to :action => "index"
end

To redirect to the last url, use:

redirect_to :back

http://api.rubyonrails.org/classes/ActionController/Base.html#M000662

If you can learn how to read api docs well, they are extremely useful, once you get the hang of them.

It's actually the destroy action that you should be dealing with if you're using Rails' resources.

def destroy
  Item.find(params[:id]).destroy
  redirect_to other_specified_path
end

If you look at the API documentation, you'll see there's a HUGE difference between the ActiveRecord::Base#delete and ActiveRecord::Base#destroy methods. Only use delete if you really understand why you're using it.

i only need this

def delete
  Item.destroy
  redirect_to :back
end

i used this if i want to back to current page
