Description

Form data successfully posted and gets updated in database. But newly inserted data does not show up in jsGrid, instead blank row is shown. Checked response separately and the controller returns newly inserted record in JSON format. Also tried with "return $.ajax" and "$.ajax", no luck in getting the data displayed in jsGrid, after browser refresh it shows up the newly inserted data. Not sure what am I missing, please help.

#--- Python  Controller `-----#`
@app.route('/user', methods=['POST'])
def add_user():
    user = mongo.db.user_mgmt
    new_user = []
    user_id = user.insert({'usr_nm':request.form['UserName'],
                           'psswd':request.form['Password'],
                           'isAdmin':request.form['isAdmin']})
    for usr in user.find({'_id':user_id}):
        new_user.append({
            'ID':str(usr['_id']),
            'UserName':usr['usr_nm'],
            'psswd':usr['Password'],
            'isAdmin':usr['isAdmin']})
    return jsonify(new_user)

//--- jsGrid client ----//
insertItem: function (item) {
	return $.ajax({
		type: "POST",
		url: "/user",
		data: item
	});
},

Research direction
The user reports that after an insert, a blank row appears instead of the new data. The server returns a JSON array with one object, but jsGrid's insertItem expects a single item object (not an array). Investigate the jsGrid documentation for the insertItem callback's expected return format. Check the server code at the Flask route '/user' to ensure it returns a single object or adjust the client side callback to handle the array. Also verify the HTTP status code is 200.
