django - RuntimeError：在带有 ib_insync 和 django 的线程“Thread-1”中没有当前事件循环

Question

我是 ib_insync 的新手，我正在用 django 实现 ib_insync。当我使用placeOrder()下订单时，我收到错误RuntimeError: There is no current event loop in thread 'Thread-1'。

我的意见.py

def placeOrder(request,  account):
    print("ACCOUNT: ", account)
    symbol = 'AAPL'
    action = 'BUY'
    strike = 145
    date = '20210430'
    quantity = 1
    currency = 'USD'
    secType = 'OPT'
    exchange = 'SMART'
    right = 'C'

    contract, order = create_contract(action, quantity, symbol, secType, date, strike, right,exchange, account)
    trade = place_order(contract, order)

以下是方法

def place_order(contract, order):
    place_order = ib.placeOrder(contract, order)

    return place_order


def create_contract(action, quantity, symbol, secType, lastTradeDateOrContractMonth, strike, right, exchange, account):

    contract = Option(symbol, lastTradeDateOrContractMonth, strike, right, exchange)
    order = MarketOrder(action, quantity)
    order.account = account

    return contract, order

错误：
