Django ModelForm ForeignKey查询

Question

我想要一个仅向用户提供其参与项目的问题的表格。

models.py：

class Project(models.Model):
    project_name = models.CharField(max_length=255, unique=True, blank=False)
    def __str__(self):
        return str(self.project_name)


class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    project = models.ManyToManyField(Project)
    def __str__(self):
        return str(self.user)

class Question(models.Model):           
    title = models.CharField(max_length=255, blank=False)
    content = tinymce_models.HTMLField(blank=False)
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    project = models.ForeignKey(Project, on_delete=models.CASCADE)
    ...
    def __str__(self):
        return str(self.title)


class QuestionForm(ModelForm):
    class Meta:
        model = Question
        fields = ['title', 'content', 'project']

在views.py中：

form = QuestionForm()
form.fields["project"].queryset = Project.objects.filter(project_name__in=request.user.profile.project.all())

但是以某种方式查询的结果始终保持为空。

也许有人知道我在想什么？

您的查询过于复杂。 您应该只直接使用用户的项目：

form.fields["project"].queryset = request.user.profile.project.all())
