Rails 3.2 UJS -> Can it grab the ID for me for a dynamic URL?

I need to construct the POST url for a resouce and the val() of the item that I am adding remote-true to will be the ID in the URL resource. IS there a rails shortcut for doing this or do I just have to do 

  data: {'id': $(this).val()}

in the jQuery ajax call?

Solution

  • Not sure I understood your problem, but I guess you want to achieve this

    data: {'id': '<%= params[:id] %>'}

    You can access the id contained in the url with params[:id] and embed this in your javascript snippet (unless it is in a .js file).

    Is this addressing your problem? If not can you please clarify / rephrase?
