I am using Rails 3.2, I have a form and I want it to be posted via ajax and have the controller return json.
I am using a form_for helper like so:
= form_for(@object, :remote => true, :format => :json) do |f|
....
My objects controller create method looks like this:
def create
respond_to do |format|
if @object.save
format.html { redirect_to @object }
format.json { render json: @object, status: :created, location: @object }
else
format.html { render action: "new" }
format.json { render json: @object.errors, status: :unprocessable_entity }
end
end
end
The form is submitting ajaxly as expected. But the controller is returning html, not json!
Inspecting the request with firebug and sure enough the Content-Type http header on the ajax request is being set to application/html.
The documentation around this is pretty sparse, :format => :json seems to just append ".json" to the forms action, not actually modify any http headers.
I've also tried :content_type => :json to no effect.
I can't simply hard code the controller to return json as there are other places where I do want it to return html...
So does anyone know how to tell the controller to render json when using form_for?
Thanks for any help
