[FIXED] Accessing Dictionary in jinja2

Issue

{% for blog in data %}
    {% with current_ids=blog.blog_id %}
    {{ like_ids }}
    {{ current_ids }}
    {{ like_ids['bar'] }}
    {% endwith %}
{% endfor %}

in above code {{ like_ids }} prints {'foo': [], 'bar': [<User: [email protected]>]} {{ current_ids }} prints foo || bar {{ like_ids['bar'] }} throws error "Could not parse the remainder: '['bar']' from 'like_ids['bar']'"

i tried like_ids.bar and it prints [<User: [email protected]>] but, like_ids.current_ids doesn't print anything

tried set instead of with and the problem still exists

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)

This is my views.py code

Solution

Change the function,

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)

To below.

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)

Change template as below.

{% for blog in data %}

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

  {{ blog.id }}


{% endfor %}

Template explanation.

{% 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 %}
