How to access Backbone Fetch data server side
@app.route('/my_url_here/<entityId>', methods=['GET', 'POST'])isn't picking up any id because you aren't sending any.
Backbone fetch uses the id field of the model to construct the fetch URL, in your case I would recommend turning the entityId into id:
BB.Politician = Backbone.Model.extend({ defaults: { type: "Politician" }, url: "/my_url_here"});var currentUser = new BB.Politician({"id": "1625"});and let Backbone construct the GET, which would look like:
"/my_url_here/" + this.get('id'); // this refers to modelwhich turns into
"/my_url_here/1625"Backbone.Model.url also accepts function as value so you can define your own logic for constructing URLs. For instance, if you must retain the entityId you can construct your url like:
url: function () { return "/my_url_here" + this.get('entityId');}
