Question

我绝对是python，django框架的初学者。我不知道如何在Django中制作自定义装饰器。我正在尝试，如果用户的个人资料已100％完成，他们可以申请工作，否则他们会显示警告消息“您的个人资料已完成，请首先完成您的个人资料，然后申请此工作”

我遵循以下代码 models.py

class profile(models.Model):
    user = models.OneToOneField(User, on_delete = models.CASCADE, primary_key=True)
    random = models.CharField(max_length=50)
    image = models.ImageField(upload_to="profile_pics")

    def __str__(self):
        return f'{self.user.username} profile'

    def get_absolute_url(self):
        return reverse('jobseeker:profile_count')



    @property 
    def percentage_complete(self):
        percent = { 'random': 50, 'image': 50}
        total = 0
        if self.random:
            total += percent.get('random', 0)
        if self.image:
            total += percent.get('image', 0)
        return total

decorators.py

def complete_profile_required(view_func):
def wrapper_func(request, *args, **Kwargs):
    if request.user.profile.percentage_complete == 100:
        print(request.user.profile.percentage_complete)
        return redirect('jobseeker:apply_job')
    else:
        return view_func(request, *args, **Kwargs)
return wrapper_func

views.py

@login_required
@jobseeker_required
@complete_profile_required
def apply_job(request):
    return render(request, 'apply_job.html')

urls.py

 path('apply_job', views.apply_job, name='apply_job')

it will returns the this error

您必须重定向到另一个视图。您收到TOO_MANY_REDIRECTS错误。因为您将其重定向到同一视图。

您必须更换装饰器

def complete_profile_required(view_func):
  def wrapper_func(request, *args, **Kwargs):
    if request.user.profile.percentage_complete == 100:
        # change your logic here
        return redirect('jobseeker:another_view')
    else:
        return view_func(request, *args, **Kwargs)
return wrapper_func
