jQuery post to Rails
You can setup your post to structure the data in any way as long as it is interpreted correctly on the rails end, but best practice is to have an object of 'model-name' with all the values.
Javascript
$.ajax({ url: "/sub_comments", type: "POST", data: {subcomment: { field: val, field2: val, etc... }}, success: function(resp){ }});Rails
def create @sub_comment = SubComment.new params['subcomment'] if @sub_comment.save render :json => { } # send back any data if necessary else render :json => { }, :status => 500 endend
