My rating controller:
def rate
@ip = request.remote_ip
@konkurrencer = Rating.where(:IP => @ip, :konkurrencer_id => params[:id])
if @konkurrencer.empty?
params[:kon][:IP] = request.remote_ip
params[:kon][:konkurrencer_id] = params[:id]
@konkurrencer = Rating.new(params[:kon])
@konkurrencer.save
@konkurrencer.konkurrencer.rating_score += params[:kon][:ratings].to_i
@konkurrencer.konkurrencer.ratings += 1
@konkurrencer.save
else
// render error message
end
render :nothing => true
end
end
My AJAX:
jQuery.ajax({
url: frm.attr('action'), //your server side script
data: frm.serialize(), //our data
type: 'POST',
success: function (data) {
//write here something when everything went ok
},
error: function (jxhr, msg, err) {
alert(msg); //something went wrong.
}
});
Have do I make my controller more DRY? And how to create a error messages that gets rendered in the ajax call.
