这是我的视图、模型和Html。我试图在django中创建一个用户配置文件页面。我只需要查询和拉取请求的信息。配置文件页面中的用户。问题似乎是我无法获得正确的查询过滤器。

视图.py

 class UserView(generic.ListView):
     model = Post
     template_name = 'post/user_page.html'
     context_object_name = 'all_post'

     def get_queryset(self):
         return Post.author.all()

class Post(models.Model):
    creator = models.CharField(max_length=250)
    post_name = models.CharField(max_length=250)
    category = models.CharField(max_length=250)
    post_photo = models.FileField()
    author = models.ForeignKey(User, blank=True, null=True, related_name ='user_post')
    category = models.ManyToManyField(Category)

    def get_absolute_url(self):
        return reverse('post:detail', kwargs={'pk': self.pk})

    def __str__(self):
        return self.creator + ' - ' + self.post_name

配置文件页面

 <div class="col-sm-6 col-sm-offset-3">
    <div class="roote-container container-fluid">
        <h1>Welcome {{user.username}}</h1>
        <div class="row">
                {% for post in all_post %}
                    <div class= col-sm-12">
