我有一个管理命令，它输出一个函数输出。但执行后会出现错误

错误是什么？如何解决

from django.core.management.base import BaseCommand
from Destinations.models import *
from LCR.views import *

class Command(BaseCommand):
    help = 'Generates a LCR when executed '

    def handle(self,*args, **kwargs):
        LCR(self)

在命令中，将命令实例本身传递给函数
就我所见，由于请求实例没有为LCR逻辑使用任何东西，所以应该将它从视图函数封装到单独的函数中，以便可以从两个位置调用它

例如：
在>leastConstrouting\LCR\views.py中定义一个新方法，例如

def get_LCR（）： #从最初的方法开始采取一切措施： emailadd=Email.objects.all（） # --- #另一个代码 #直至：打印（费率表）返回{“ratelist”：ratelist，“emailadd”：emailadd}
然后在LCR方法中调用它，如：
在您的命令方法中，例如：

当你还没有显示命令的代码时，我们怎么回答这个问题？@DanielRoseman请现在检查一下。我忘了加上它，这根本没用。什么是LCR？@DanielRoseman LCR是一个返回该输出的函数。我将用代码更新问题。@DanielRoseman也请看一看我之前问的问题。如何封装？
