if a have a query like

    following = Relations.objects.filter(initiated_by = request.user)

in which i'm having all the users followed by the currently logged in user, and i want to display those user's blog posts. Using a query like:

    blog = New.objects.filter(created_by = following)

it only shows me the blog posts of the user with the id = 1 (though the currently logged in user doesn't actually follow him) in template i have :

{% for object in blog %}
<a href='/accounts/profile_view/{{object.created_by}}/'> {{object.created_by}}</a> <br /> 
{{object.post}}<br />
{% endfor %}

Where am i wrong?
