python - Fom缺少1个必需的位置参数:形式为“request”

我正在尝试使用以前的stackoverflow答案和Google来获取表格工作，但似乎没有任何工作适合我。

我有一个模型项目和一个项目团队，我希望用户能够从他创建的团队中选择一个并将其链接到项目。

我正在使用一个名为MyUser的自定义用户

这是我的表格，以便选择一个团队：

from django import forms
from django.contrib.auth.models import User
from registration.models import MyUser
from .models import Project, Team
from django.contrib.auth import get_user_model

User = get_user_model()

class EditSelectTeam(forms.Form):

    team_choice = forms.ModelChoiceField(widget=forms.RadioSelect, queryset=None)

    def __init__(self, User, request, *args, **kwargs):
        super(EditSelectTeam, self).__init__(*args, **kwargs)
        self.fields['team_choice'].queryset = Team.objects.all().filter(team_hr_admin = request.User)

我的看法：

def TeamSelect(request):
    if request.method == "POST":
        select_form = EditSelectTeam(request.user, request.POST)
        if select_form.is_valid():
            print('sucess')
        else:
            print('Fail')

    else:
        select_form = EditSelectTeam(request)
    return render(request,'link_project.html',
                            {'select_form':select_form })

如果以我的形式输入request.User，我认为该错误是：

TypeError: __init__() missing 1 required positional argument: 'request'

如果我没有在__init__中放置用户，则会得到表格，但是单击POST时会出现错误

AttributeError: 'MyUser' object has no attribute 'user'

最佳答案

您的__init__方法采用User和request，

def __init__(self, User, request, *args, **kwargs):

但您只能将以下其中一项传递给表单：

select_form = EditSelectTeam(request.user, request.POST)
...
select_form = EditSelectTeam(request)

我将__init__方法更改为仅采用user（小写），

def __init__(self, user, *args, **kwargs):
    super(EditSelectTeam, self).__init__(*args, **kwargs)
    self.fields['team_choice'].queryset = Team.objects.all().filter(team_hr_admin=user)

然后将视图更改为始终通过request.user。

select_form = EditSelectTeam(request.user, request.POST)
...
select_form = EditSelectTeam(request.user)
