Django Class based views Context data
Example
Sometimes, your template need a bit more of information. For example, we would like to have the user in the header of the page, with a link to their profile next to the logout link. In these cases, use the get_context_data method.
views.py
class BookView(DetailView):
template_name = "book.html"
def get_context_data(self, **kwargs)
""" get_context_data let you fill the template context """
context = super(BookView, self).get_context_data(**kwargs)
# Get Related publishers
context['publishers'] = self.object.publishers.filter(is_active=True)
return context
You need to call get_context_data method on the super class and it will return the default context instance. Any item that you add to this dictionary will be available to the template.
book.html
<h3>Active publishers</h3>
<ul>
{% for publisher in publishers %}
<li>{{ publisher.name }}</li>
{% endfor %}
</ul>
