django中 引用了User表, 获取到了登录名,怎样让他和我生成的用户名进行比对,加个关联的话 可以比对,但是新建的用户,没有关联数据会报错.我把用户也和别的数据关联了,这个问题怎么解决.

我的代码:

def customer(request):

    """显示我的客户"""

    businessList = Business.objects.filter(busOwner=request.user).filter(state= True)

    for i in businessList:

        if i.busOwner != request.user:

            return render(request,'myApp/sos.html')

        else:

            customerList = i.customer_set.all()  

            context ={"customer":customerList,"i":i}

            return render(request,"myApp/customer.html", context)

报错提示:

The view myApp.views.customer didn't return an HttpResponse object. It returned None instead.
