AJAX request with Rails 3 and jQuery is being processed as HTML. :O

Question

Hi,

I have a form that i want submitting with AJAX, using rails 3 and jquery. The problem that I am facing is that rails is responding to the AJAX request as HTML too. After a little search I found that this has something to do with the correct Accept headers not being passed. How do i fix this?

This is the controller code

  respond_to do |format|
    format.js { render 'user/create' }
    format.html { redirect_to ((params[:feed][:url].nil?)?url_for(:home) : params[:feed][:url]) }
  end

It seems to work on a friends firefox, and on my chrome too, smthng wrong with my firefox?

UPDATE: It seems that the error arises only when I use a proxy service as JonDo, which probably changes the accept headers... Is there a way to force rails to use js format if the X-requested-by header is present?

Thanks

Answer 1

Your controller code looks correct. Are you sure that you have added the .js suffix to the AJAX URL in your form? That's how the responder knows what format you want for the response. The default format is HTML so omitting the suffix would look like it's responding to a HTML request.

You likely didn't set the dataType properly. See the docs (this is &.post) If you set dataType to "js" you'll be all good!
