运行脚本时，Atom `script` 插件无法识别 Django 模型/设置

Question

在尝试使用 atom 附加组件 script 在基于 Django 的 Web 应用程序中运行 python 脚本时，我似乎遇到了一些依赖问题。

我想使用 Atom script 插件运行以下脚本：

feeder.py：

import zmq
import time
from time import sleep
import uuid
from models import AccountInformation

context = zmq.Context()
zmq_socket = context.socket(zmq.PULL)
zmq_socket.bind("tcp://*:32225")
time.sleep(1)


while True:
    try:
        msg = zmq_socket.recv_string()
        data = msg.split("|")
        print(data)
        if (data[0] == "account_info"):
            version = data[1]
            DID = uuid.UUID(data[2])
            accountNumber = int(data[3])
            broker = data[4]
            leverage = data[5]
            account_balance = float(data[6])
            account_profit = float(data[7])
            account_equity = float(data[8])
            account_margin = float(data[9])
            account_margin_free = float(data[10])
            account_margin_level = float(data[11])
            account_currency = data[12]

            feed = AccountInformation(
                    version=version,
                    DID=DID,
                    accountNumber=accountNumber,
                    broker=broker,
                    leverage=leverage,
                    account_balance=account_balance,
                    account_pofit=account_profit,
                    account_equity=account_equity,
                    account_margin=account_margin,
                    account_margin_free=account_margin_free,
                    account_margin_level=account_margin_level,
                    account_currency=account_currency
            )
            feed.save()
            # Push data to account information table
        else:
            print("no data")
    except zmq.error.Again:
        print("\nResource timeout.. please try again.")
        sleep(0.000001)

不幸的是，它引发了以下错误：

当我删除模型导入时，一切都运行良好，它不会填充我的数据库，因为我需要导入的模型...

如何解决这个问题？

Answer 1

您的模型在您的应用中，您的应用在您的设置中 (INSTALLED_APPS)，因此您应该先配置 django 的设置，然后才能访问它们。

只需在导入您的模型之前添加这些：

import django
django.setup()

您还应该设置DJANGO_SETTINGS_MODULE 环境变量来指定您的设置文件；如果您愿意，也可以使用django.configure (docs)。
