    <p>As we know, if we want to access user session from context within a inclusion tag, you can use <code>takes_context</code> argument and pass a request context in the view.</p> <p>But in my project, it is more complicated:</p> <p>The view is simple:</p> <pre><code># views.py def index(request): form = PersonForm() return render(request, 'add.html', {'form': form}) </code></pre> <p>Templates:</p> <pre><code># templates/add.html &lt;html&gt; &lt;head&gt; &lt;title&gt;Add Person&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form enctype="multipart/form-data" action="" method="post"&gt; {{ form.as_p }} &lt;/form&gt; {% render_attachments %} ... &lt;/body&gt; &lt;/html&gt; # templates/list.html {% load my_tags %} &lt;div class="attachments" style="margin:12px 0 12px 0;"&gt; {% for attachment in attachments %} &lt;a href="{{ attachment.attachment_file.url }}"&gt;{{ attachment.filename }} &lt;/a&gt; {% attachment_delete_link attachment %} {% endfor %} &lt;/div&gt; </code></pre> <p>Here is my custom tags:</p> <pre><code># my_tags.py @register.inclusion_tag('attachments/list.html', takes_context=True) def render_attachments(context): session = context['request'].session return {'attachments': session.get('attachments', [])} @register.inclusion_tag('attachments/delete_link.html', takes_context=True) def attachment_delete_link(context, attachment): if context['user'] == attachment.creator: return { 'delete_url': reverse('delete_attachment', kwargs={'attachment_pk': attachment.pk}) } return {'delete_url': None} </code></pre> <p>When i run my project, i got the following error:</p> <pre><code>KeyError at /person/ 'user' Request Method: GET Request URL: http://localhost:8000/person/ Django Version: 1.5.1 Exception Type: KeyError </code></pre> <p>So, i print context out within two tags to find out what happened, it seemed that the request context does not passed into <code>attachment_delete_link</code>, how can i resolve this problem?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
