Question

我在其中一个选择字段中使用Django User模型。但是，我无法仅传递链接到commmon组织/公司的用户。

我为每个用户链接了一个onetoone个人资料。这个对于onetoone模型再次与组织模型相关联。

现在需要一个表单，其中select字段应该将用户链接到组织模型。

这是我的form.py：

class taskaddform(forms.ModelForm): 
    def __init__(self,user, *args, **kwargs):
        self.user = kwargs.pop('user', None)
        self.request = kwargs.pop('request', None)
        super(taskaddform, self).__init__(*args, **kwargs)
        self.fields["assigned_to"].queryset=User.objects.filter(company=self.request.user.company.entity)   
    class Meta:
        model=tasktable
        fields=('task','assigned_to','discription','documents',)

views.py：

@login_required
def taskadd(request):
    if request.method=='POST':
        form=taskaddform(request.POST,request.FILES,request.user)
        if form.is_valid():
            new_form=form.save(commit=False)
            new_form.created_by=request.user
            new_form.company=request.user.company.entity
            new_form.save()
            return HttpResponseRedirect(reverse('taskadd'),messages.add_message(request, messages.SUCCESS,'Task added succesfully.'))
    else:
            form=taskaddform(request.user) 

    return render(request,'taskadd.html',{'form':form})

更新了views.py。

@login_required
def taskadd(request):
    if request.method=='POST':
        form=taskaddform(request, request.POST,request.FILES,request.user)
        if form.is_valid():
            new_form=form.save(commit=False)
            new_form.created_by=request.user
            new_form.company=request.user.company.entity
            new_form.save()
            return HttpResponseRedirect(reverse('taskadd'),messages.add_message(request, messages.SUCCESS,'Task added succesfully.'))
    else:
            form=taskaddform(request) 

    return render(request,'taskadd.html',{'form':form})

并在您的forms.py -

中

class taskaddform(forms.ModelForm): 
    def __init__(self, request, *args, **kwargs):
        self.request = request
        super(taskaddform, self).__init__(request, *args, **kwargs)
        self.fields["assigned_to"].queryset=User.objects.filter(company=self.request.user.company.entity)

Django：'NoneType'对象没有属性'user'
