< H1 > place an order < / H1 >

def post_order_place (request):

"""

apiid,symbol,timestamp
type: buy-limit/sell-limit

"""  
timestamp = create_timestamp()
data = dict(request.POST)
print(data)
print(data.items)

for key, value in request.POST.iteritems():
    if "price" in key:
        price[key] = value
    if "quantity" in key:
        quantity[key] = value
    if "type" in key:
        type[key] = value

price = data["price"]
quantity = data["quantity"]
type = data["type"]
print(price)
print(quantity)
print(type)

what result do you expect? What is the error message actually seen?

to solve the problem of error reporting, I did not use dict before defining the function, but dict (request.POST) reported an error
error message: UnboundLocalError: local variable "dict" referenced before assignment

in the for loop, neither your price, quantity nor your type is initialized to dict, so you just use them as dict

for key, value in request.POST.iteritems():
    if 'price' in key:
        data['price'] = value
    if 'quantity' in key:
        data['quantity'] = value
    if 'type' in key:
        data['type'] = value
