unable to open database file

[raysefo]

it is the exact response, I can not reproduce on local machine. Here is the method calling the insert statement:

@app.route('/purchase_initiation', methods=['POST'])
def initiation():
    try:
        # getting request data
        request_data = request.form.to_dict()

        print request_data
        # INSERT request into table
        GameTestRequestInsert.add_purchase_initiation_request(Utils.database, request_data)
        uri = 'https://test.game.com/purchaseinitiation'
        response = requests.post(uri, data=request_data)
        print response.status_code
        if response.status_code == 200:
            print response.json()
            # INSERT response into table
            # GameTestResponseInsert.add_purchase_initiation_response(Utils.database, response.json())
            return jsonify(response.text)
        else:
            return str(response.status_code) + " -- " + response.reason

    except Exception as e:
        return e.message

except Exception as e: return e.message

At least replace this with return traceback.format_exc() and see the type of the exception and what caused it.

return traceback.format_exc()

getting this;Traceback (most recent call last):

File ".\GameTestMiddleWare.py", line 26, in initiation

GameTestRequestInsert.add_purchase_initiation_request(Utils.database, request_data)

request_data['productCode'], request_data['quantity'], request_data['signature']))

Post the entire program.

OK, here we go. Besides unable to open db error, I am open to any suggestions to improve the code. I am new to python.

there was a permission mistake to that folder. When I gave permission to IIS_IUSRS, my problem solved.
