Getting Form Data With Flask

When getting from data in Flask, can I somehow bind html elements and their values to an object without using Jinja templating. Or do I have to send the data via a manual HTTP Pos

Solution 1:

I think what you are really asking is "given a client-side JavaScript object, how can I serialize it so that I can easily access the data server-side". If that is your question, there are two ways to do so:

1. The way you provided in your answer, serializing your object as JSON and submitting it as the body of your POST request:

   @app.route("/user", methods=("POST",))defsave_user():
       data = request.get_json()
       # ... etc. ...

2. Using FormData on the client side:

   var yourUser = {
       firstname: "Joe",
       lastname: "Smith",
       email: "joe@smith.com",
       password: "12345"
   };
   
   var formData = new FormData();
   Object.keys(yourUser).forEach(function(key) {
       formData.append(key, yourUser[key]);
   });
   // Post formData back to your controller using XHR

   combined with the normal request.form access on the server side:

   @app.route("/user", methods=("POST",))defsave_user():
       data = request.form
       # ... etc. ...

Solution 2:

Solve the issue with this

@app.route('/post/user',methods=['POST','GET'])
def saveuser():
 data = json.loads(request.data)
 firstname = data['firstname']
 newuser = User(firstname,lastname,email,password)

 db.session.add(newuser)
 db.session.commit()

first I get the json string from request.data, then i parse it into a dict and save it to my db
