Question

I am trying to post a form to a Rails controller using jQuery and AJAX however I am getting this error:

Started GET "/subscription_mails/14/create_recipients?utf8=%E2%9C%93&_method=put&authenticity_token=8HtssDY3kxnRlplQbBGlpUspL5ZLq4PqdgiiL5d73yQ%3D&group_ids%5B%5D=3&subscription_mail%5Btarget_users%5D=0&subscription_mail%5Btarget_owners%5D=0&subscription_mail%5Btarget_teachers%5D=0&subscription_mail%5Btarget_teachers%5D=1&subscription_mail%5Btarget_subscribers%5D=0" for 127.0.0.1 at 2012-11-29 19:59:47 +0000

I am not sure why I am getting this error as I have the path defined in my routes. This is my form:

{ :id => “mail-form”, :method => :put } do |f| %>

This is the code in my routes file:

  resources :subscription_mails do
    put 'create_recipients' => "subscription_mails#create_recipients"
  end

And this is my jQuery:

$('#save-config').click(function(){
  $.ajax({
    url: $('form#mail-form').attr('action'), //sumbits it to the given url of the form
    data: $('form#mail-form').serialize(),
    dataType: "JSON" // you want a difference between normal and ajax-calls, and json is standard
  }).success(function(json){
  //act on result.
  });
  return false; // prevents normal behaviour
});

I’m struggling to figure this out and would really appreciate some help.

Looks like your AJAX request is using the GET verb (default), rather than PUT, which is what you defined in the route. Run rake -T to confirm required method and path, then in your AJAX, add type: 'PUT', in there somewhere.
