在jinja2中访问字典

更改功能,

def bloglist(request):
like_ids = {}
blog_data = Blog.objects.select_related('published_by').filter(status='Published').all()
for blog in blog_data:
    blog.comment = blog.blogcomment_set.select_related('commented_by').all()
    blog.like = blog.bloglike_set.select_related('liked_by').all()
    like_ids[blog.blog_id] = [like.liked_by for like in blog.like]
args = {
    'data': blog_data,
    'like_ids': like_ids
}
print(args)
return render(request, 'bloglist.html', args)

到下面。

def bloglist(request):
    blog_data = Blog.objects.select_related('published_by').filter(status='Published').all()
    args = {
        'data': blog_data,

    }
    print(args)
    return render(request, 'bloglist.html', args)

更改模板如下。

{% for blog in data %}

  {% for like in blog.bloglike_set.all %}
    {{ like.id }}
  {% endfor %}

  {{ blog.id }}


{% endfor %}

模板说明。

{% for blog in data %}

# ALL THE IDs OF LIKES OF CURRENT BLOG
  {% for like in blog.bloglike_set.all %}
    {{ like.id }}
  {% endfor %}


# CURRENT BLOG ID
  {{ blog.id }}



{% endfor %}

你可以访问下面的词典。

<ul>
{% for key, value in data.items %} 
  <li>{{key}} - {{value}}</li>
{% endfor %}
</ul>

你为什么这么做,

{% for blog in data %}
    {% with current_ids=blog.blog_id %}
    {{ like_ids }}
    {{ current_ids }}

而你可以做到这一点。

{% for blog in data %}
    {{ like_ids }}
    {{ blog.blog_id }}
