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

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)
