python - Flask: proper way of using routes and functions

Question

I wrote a small flask server. However, one of the routes was getting large so i thought of creating an external .py file, that contains all the logic in a function, and when the route gets executed, it simply calls that function in that different python file.

However, i also had to get parameters from a form. So my new route was:

@app.route('/convert', methods=['POST'])
conversion_item = request.form.get('item')
conversion_method = request.form.get('method')
#HERE CALL THE FUNCTION
convertMy(conversion_item, conversion_method)
return redirect(url_for('index'))

However, when i execute this, i get:

  File "server.py", line 24
    conversion_item = request.form.get('item')
    ^
SyntaxError: invalid syntax

Do i have to put everything in that route inside a function? Then i will have a function under that route, that will call another function? That seems weird to me.

How can i "glue" this?

Answer 1

the @ in @app.route represents a function decorator, it has to decorate a function. It is perfectly normal for a function to call another function.

@app.route('/convert', methods=['POST'])
def convert():
    conversion_item = request.form.get('item')
    conversion_method = request.form.get('method')
    #HERE CALL THE FUNCTION
    convertMy(conversion_item, conversion_method)
    return redirect(url_for('index'))
