Flask Python, trying to return list or dict to Ajax call

Question

Within a Flask app, I have the following ajax call:

    $.ajax({
            url: \"{{ url_for( \'bookings.get_customer\' ) }}\",
            type: \"POST\",
            


        

Answer 1

josonify works..but if you intend to just pass an array without the 'results' key, you can use json library from python. The following conversion works for me..

 import json

 @app.route('/test/json')
 def test_json():
 list = [
        {'a': 1, 'b': 2},
        {'a': 5, 'b': 10}
       ]
 return json.dumps(list)

Answer 2

Flask doesn't expect that you will return list object from your view function. Try jsonify it before:

from flask import jsonify

@bookings.route( '/get_customer', methods=[ 'POST' ] )
def get_customer():
    name = {}
    for key, value in request.form.items():
        name[ key ] = value

    customer_obj = customer_class.Customer()
    results = customer_obj.search_customer( name )

    return jsonify(customers=results)    

Answer 3

You need to do

return jsonify(result=your_result)

Also check documentation which could be really helpful.
