Rails 3.2 jQuery JSONP request not working - Moved Permanently

I am trying to send a POST request ( ‘remove_tag_named’ )and getting a simple OK back on success ; it doesn’t work…

the post is correctly sent , but after then it’s looping on sending a GET request to the same url, with the error

301 Moved Permanently

I should not be far fro the solution, but I am stuck :

In my routes.rb

namespace :administration do

resource :dashboards, :only => :show do

collection do

post :remove_tag_named

end

end

end

In my view :

**= link_to t(:delete), "#", :id => :delete_tag_link**

generated html =>

  • remove
  • my js.coffee script ( # this should be using JSONP I guess )

    $(’#delete_tag_link’).bind “click”, (e) ->

    selected = $(’#tags.tab-pane.active #tag-list li span.myTag.selected’)

    tagName = selected.html()

    alert 'going remove tag: ’ + tagName # checking I get the correct tag value

    $.ajax

    url: “/” + locale + “/administration/dashboards/remove_tag_named.json”

    type: “POST”

    dataType: “json”

    contentType: “json”

    data: {“tag_name”: tagName }

    success: (result) ->

    selected.remove()

    I have also set an init js

    $.ajaxSetup beforeSend: (xhr) ->

    xhr.setRequestHeader “X-CSRF-Token”, $(“meta[name=“csrf-token”]”).attr(“content”)

    and the console output :
