Python '；QueryDict&x27；对象没有属性'；用户'；

我目前在Django做我的项目，我需要外键（名称）分别显示给当前用户。它显示得非常好，就像我想要的一样，但是在我提交表单时它抛出了一个错误，“QueryDict”对象没有“user”属性

错误消息

        form = EmployeeForm(req)

因此，不要使用

form=EmployeeForm（req）

而使用

form=EmployeeForm（request）

或

form=EmployeeForm（request.user）

更改

form = EmployeeForm(req)

表单需要一个请求对象作为参数，但您向它传递了一个

名称的查询集

谢谢大家的回复。我设法消除了这个错误。我没有在POST方法中传递请求参数

谢谢你的回答：），但我也试过了，错误仍然是一样的。谢谢你的回答，我已经传递了参数'request'，并将forms.py更改如下，self.fields['designation'].queryset=designation.objects.filter（user=req.user）仍然得到相同的错误。但是外键是根据用户进行完美过滤的，在提交表单时，它会抛出与您希望在表单中执行的相同的错误，因为问题出在表单的init方法

self.fields['designation'].queryset=req.user.designation.all（）

我已经纠正了错误bro！。。。但它抛出了另一个错误NOTNULL约束失败：emp_employee.designation_ids显示完整的错误跟踪和更多代码，以便我们可以跟踪所涉及的名称（

req

，

request

，

DesignationForm

）。添加了更多代码，我希望这将有助于跟踪错误。感谢您的回答，我已经传递了参数'request'，并将forms.py更改如下，self.fields['designment'].queryset=designation.objects.filter（user=req.user）仍然得到了与抛出另一个错误相同的错误---非空约束失败：emp_employee.designation_id
