React JS with Rails - Accessing JSON data with URL

Question

I'm learning how to use React JS with my Rails app. Disclaimer: This is the first time I am messing around with JS!

I'm following a talk by Michael Chan at Rails Conf . Everything works beautifully until I hit the CommentsContainer part, where he fetches the comments data from a Rails route. I am trying to the same thing, except on a simple Songs controller (generated with a scaffold, having name and artist as the attribute).

I am getting stuck at the part where he fetches this data with the path, I end up with a 500 error page when I try to run the code. I don't know how to debug my React code, since the browser console is just showing a 500 error.

Here's my view,

<%= react_component "SongsContainer", { songsPath: songs_path } %>

And here's my React code,

var SongsContainer = React.createClass({
componentWillMount(){
    this.fetchSongs();
    setInterval(this.fetchSongs, 1000);
},

fetchSongs() {
    $.getJSON(
        this.props.songsPath,
        (data) => this.setState({songs: data});
    );
},

getInitialState() {
    return { songs: [] };
},

render() {
    return <Songs songs={this.state.songs} />;
}
});

Any help would greatly be appreciated! I'm just looking at this 500 page not knowing what to do.

EDIT: Adding Server log

Answer 1

Finally after lots of struggle, I found a solution!

Remove Turbolinks from application.html.
Replace the $.getJSON function with this,
$.ajax({ url: this.props.songsPath, dataType: 'json', success: function(data) { this.setState({songs: data}); }.bind(this) });

Now, I really don't know much about JS, so I don't know why this works, but it just does! Cheers.
