Question

我正在尝试将查询集传递给表单的字段。我试图显示由当前项目过滤的开发人员（我通过slug获得当前项目）。不幸的是，我收到了一个错误global name 'project' is not defined。似乎参数没有从表单实例传递到forms.py文件或其他东西......

这是我的forms.py:

class TaskForm(ModelForm):
    class Meta:
        model = Task
        fields = ('iteration', 'story', 'description',  )

    def __init__(self, *args, **kwargs):
        self.project = kwargs.pop('project')
        super(TaskForm, self).__init__(*args, **kwargs)
        self.fields['developer'] = forms.ModelMultipleChoiceField(queryset = Developer.objects.filter(project = project)) # this is where I want my objects to filter

这就是我初始化表单的方式：

project = Project.objects.get(user=user, slug=slug)
taskForm = TaskForm(request.POST, project = project)

这是模型：

class Developer(models.Model):
task = models.ManyToManyField(Task)

我认为解决方案非常明显，但我无法让它发挥作用。

您正在尝试调用未定义的变量项目。
请改用 self.project 。

def __init__(self, *args, **kwargs):
    self.project = kwargs.pop('project')
    super(TaskForm, self).__init__(*args, **kwargs)
    self.fields['developer'] = forms.ModelMultipleChoiceField(queryset = Developer.objects.filter(project = self.project))

Django MultipleChoiceField和模型实例
