在Django模板中获取用户信息并检查是否等于作者姓名

Question

我无法查询用户名，无法与作者进行比较。它适用于下面发布的一个案例。

{% if user.is_authenticated %}
    {% if user.get_username == blog.author %}
        <a href="{% url 'update' pk=blog.pk %}"><i class="fas fa-pen fa-2x fa-spin"></i></a>
    {% endif %}
    {% if user.is_superuser %}
        <a href="{% url 'update' pk=blog.pk %}"><i class="fas fa-pen fa-2x fa-spin"></i></a>/
        <a href="{% url 'delete' pk=blog.pk %}"><i class="fas fa-trash-alt fa-2x fa-spin"></i></a>
    {% endif %}
{% endif %}

我的看法

@login_required(login_url='login')
def update_post(request, pk):
    post = get_object_or_404(Post, pk=pk)
    if request.method == 'POST':
        form = EditPost(request.POST, request.FILES, instance=post)
        if form.is_valid():
            post = form.save(commit=False)
            post.author = request.user
            post.last_edited = timezone.now()
            post.save()
            return redirect('blog', pk=post.pk)
    else:
        form = EditPost(instance=post)
        context = {'form': form}
    return render(request, 'blog/edit_post.html', context)

我的模型

class Post(models.Model):
    author = models.ForeignKey('auth.User', on_delete=models.CASCADE)
    title = models.CharField(max_length=200, null=True)
    text = models.TextField()
    created_date = models.DateTimeField(default=timezone.now)
    pub_date = models.DateTimeField(blank=True, null=True)
   last_edited = models.DateTimeField(null=True, blank=True)

    def __str__(self):
        return f'{self.title}  by  author  {self.author}'

但它适用于

{% for comment in blog.comments.all %}
    <cite>{{ comment.author }}</cite>
    <time class="comment__time">{{ comment.created_date }}</time>
    {% if user.is_authenticated and request.user.username == comment.author %}
    <a class="reply" href="{% url 'remove' pk=comment.pk %}">remove</a>
    {% endif %}
    <div class="comment__text">
    <p>{{ comment.comment }}</p>
{% endfor %}

对于这个模型是

class Comment(models.Model):
    post = models.ForeignKey('blog.Post', on_delete=models.CASCADE, related_name='comments')
    author = models.CharField(max_length=50, null=True)
    comment = models.TextField()....

    def __str__(self):
        return f'{self.comment} by user {self.author}'

Answer 1

尝试打印输出 request.__dict__ 以查看其中的所有数据，以及 check 上下文中的内容。
什么是错误信息，有吗？

Answer 2

最后我发现 solution.It 会像

    {% if user.is_authenticated and if request.user == blog.author or if user.is_superuser %}
        <a href="{% url 'update' pk=blog.pk %}"><i class="fas fa-pen fa-2x fa-spin"></i></a>
        <a href="{% url 'delete' pk=blog.pk %}"><i class="fas fa-trash-alt fa-2x fa-spin"></i></a>
    {% endif %}

而不是

    {% if user.get_username == blog.author %}
        <a href="{% url 'update' pk=blog.pk %}"><i class="fas fa-pen fa-2x fa-spin"></i></a>
    {% endif %}
    {% if user.is_superuser %}
        <a href="{% url 'update' pk=blog.pk %}"><i class="fas fa-pen fa-2x fa-spin"></i></a>/
        <a href="{% url 'delete' pk=blog.pk %}"><i class="fas fa-trash-alt fa-2x fa-spin"></i></a>
    {% endif %}
{% endif %}
