推荐答案

所以答案取决于您的模型设置.

So the answer depends on your model setup.

例如，如果您的models.py看起来像这样:

For example, if your models.py looks like this:

class Post(models.Model)
    user = models.ForeignKey(User)
    content = models.CharField(max_length=500)
    ...

    def __str__(self):
        return self.user

然后，如果您想要所有已登录用户的帖子，则可以使用此代码，例如，在请求中，您可以使用 filter 过滤出与某个参数(在本例中为 user )匹配的适当帖子:

Then if you wanted all of the posts of the user that is logged in, you would use this code, for example, in your request you would use filter to filter out the appropriate posts that match a certain parameter (in this case user):

def index_page(request):
    logged_in_user = request.user
    logged_in_user_posts = Post.objects.filter(user=user)

    return render(request, 'index.html', {'posts': logged_in_user_posts})

然后，例如，您可以这样操作 index.html 文件中的此 queryset :

Then, for example, you could manipulate this queryset in your index.html file as such:

<div>
{% for post in posts %}

    Username: {{ post.user.username }}
    Post: {{ post.content }}

    <br>

{% endfor %}
</div>
