Question

目前我有以下结构。

我有用户，可以是教师或学生。学生可以为老师留下评论。我为教师设置了详细视图，并为get_context_data添加了“评论”属性，以循环浏览评论以显示它们。

目标：作为学生的每个用户都可以提交对教师的评论。我想在详细视图的底部显示一个表单。如果用户已经有过评论，那么我们会调用update。如果用户没有审核，我们会创建它。

的 Models.py

class Teacher(models.Model):
    user = models.OneToOneField(User, on_delete=models.PROTECT, related_name='Teacher')
    availability = models.BooleanField(default=False)

    def __str__(self):
        return self.user.username

class Student(models.Model):
    user = models.OneToOneField(User, on_delete=models.PROTECT, related_name='Student')
    teacher = models.ForeignKey(Teacher)
    reviewed = models.BooleanField(default=False)

    def __str__(self):
        return self.user.username

class Review(models.Model):
    teacher = models.ForeignKey(Teacher)
    student = models.OneToOneField(Student, on_delete=models.PROTECT, related_name='Student')
    star = models.IntegerField(default=5)
    body = models.TextField()

Views.py

class ReviewSubmitForm(forms.Form):
    star = forms.IntegerField()
    body = forms.CharField()

class TeacherView(generic.DetailView):
    model = Teacher

    def get_context_data(self, **kwargs):
        # Call the base implementation first to get a context
        context = super(TeacherView, self).get_context_data(**kwargs)
        # Add extra context from another model
        context['reviews'] = Review.objects.filter(teacher_id=self.kwargs['pk'])
        context['rating'] = Review.objects.filter(teacher_id=self.kwargs['pk']).aggregate(Avg('star'))
        context['form'] = ReviewSubmitForm()
        return context

class ReviewSubmit(SingleObjectMixin, FormView):
    template_name = 'users/teacher_detail.html'
    form_class = ReviewSubmitForm
    model = Review

    def post(self, request, *args, **kwargs):
        if not request.user.is_authenticated:
            return HttpResponseForbidden()
        self.object = self.get_object()
        return super(ReviewSubmit, self).post(request, *args, **kwargs)

    def get_success_url(self):
        return reverse('users:detail', kwargs={'pk': self.object.pk})

我现在能够看到form并在我的模板中使用它。

我的教师视图位于/users/<pk>

我想要的逻辑是：寻找，检查当前的学生ID。

如果有pk = pk和student_id = student_id的条目，则加载更新表单。否则，如果是学生加载创建表单。

This example有些相似，但不完全相同。

修改： form_template.html

{% for field in form %}
<div class="form-group">
    <span color="red">{{ field.errors }}</span>
    <label>
        {{ field.label_tag }}
    </label>
    <div>{{ field }}</div>
</div>
{%  endfor %}

Django：包含评论的DetailView。使用update / create添加评论表单
