Unable to fetch Rails response through Ajax

Whenever I make a post request from my phonegap app (using ajax in javascript) to my rails server, the post goes through successfully. However, I do not receive any response from the server which ultimately leads to failure. It's puzzling why I'm unable to retrieve the response...

Here is an example of my signup script in Javascript using ajax:

$('#sign-up-button').click(function(e) {
        var str = $("#signUpForm").serialize();
        $(".error").remove();
        e.preventDefault();
        $.ajax({url: "http://localhost:3000/api/users.json",
            type: "POST",
            data: str,
            success: function(result, status) {
                alert('success');
                $.mobile.changePage( "welcome.html", { transition: "slide"} );
            },
            error: function(result) {
                alert('error');
            }
    });
});     

And this is my code on the Ruby on Rails side:

# POST /users
  # POST /users.json
  def create
    @user = User.new(params[:user])

    respond_to do |format|
      if @user.save
        format.html { redirect_to @user, notice: 'User was successfully created.' }
        format.json { render json: @user, status: :created }
      else
        format.html { render action: "new" }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end

When checking in firebug, I see the message "201 Created", indicating that the user has been created. However, since I receive no response, the "alert('error')" message pops up...

Appreciate any advice and guidance on how to resolve this issue! Thanks!

Answer №1

In order to receive an empty response like a 201, you must include dataType: 'text' in your $.ajax settings. The current issue is that jQuery is trying to interpret the response as JSON, but it can't do so because there is no response to interpret.

Answer №2

Recently, I decided to give up on trying to get it to work with Firefox and instead opened it in X-code. Surprisingly, it worked flawlessly.

I started to question whether I needed a server to receive a response from a post. Does anyone happen to know if X code automatically generates a server?
