JavaScript Rails 4 trying to parse POST JSON in controller
I have a controller with the path to create a row in my db
The page model.js has a function that does an ajax post
function autoSaveVideo(playPos){
$.ajax({
type: "POST",
url: "/video_views/create",
dataType: "json",
data: {
play_position: 0,
user_id: $('.user_id').text(),
video_id: $('.video_id').text()
},
error: function (data) {
console.log(data);
return data
}
});
setTimeout(autoSaveVideo, 6000);
I then have the controller
render :nothing => true, :status => 200, :content_type => :json
this sends a successful 200 response
but if I add to the video_views_controller.rb <-- edit and note: not Videos controller
jData = JSON.parse(request.body.read)
I get an 795: unexpected token, in the console
how do I parse it so that I can access the data object?
Pardeep is almost correct. You'll need to use params method to access the values in the data object you sent. So params['play_position'], etc.
It is a security best practice to explicitly list the keys you're expecting and permitting. See Rails Guide for strong parameters.
