Issue with Backbone model not properly processing JSON response during POST save operation

I am facing an issue with saving my model to the server and returning the ID along with other attributes. It appears that the response is being accepted as a string instead of a JSON object, leading to the entire string being added. I am using the express framework on the server side and the express-json module to serve the JSON response, which I have used successfully in the past by calling the res.json(dataObject) function. Can anyone help me figure out what might be going wrong? Feel free to take a look at the images provided or ask for more details.

Answer №1

I was able to successfully troubleshoot the issue at hand. It turned out that the problem stemmed from the response being transmitted as plain text instead of having the appropriate JSON header. To rectify this, I made sure to include an "accepts" header in the request. Without this, Express would not permit me to set the correct "content-type" header for the response. Consequently, Backbone would struggle to parse it accurately. For those curious, here is the snippet I added to the options object within my jQuery AJAX call in the sync method of the Backbone model:

beforeSend: function(xhr) {
    xhr.setRequestHeader("accept", "application/json");
}
