I would like to return in my Link.html the number of links contained in allLinks
JSON variable.
So far I guess I misunderstand the use of get_context_data()
and how to pass in context['CountLink']
the total count of links for each Post
.
With the current code, I got:
Liste des recherches
terre : <QuerySet [<Post: terre>, <Post: océan>]> Links océan : <QuerySet [<Post: terre>, <Post: océan>]> Links
models.py
class Post(models.Model):
title = models.CharField(max_length=255)
url = models.URLField(max_length=255)
allLinks = models.JSONField()
def __str__(self):
return self.title
views.py
class LinkView(ListView):
model = Post
template_name = 'link.html'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['CountLink'] = Post.objects.all()
return context
Link.html
{% for post in object_list %}
<li>
<a href="{% url 'DetailLink' post.pk %}">{{ post.title }}</a> :
{{CountLink}} Links
</li>
{% endfor %}
Example of allLinks
: {"0": "github.com/kubernetes/kubernetes/releases/tag/v1.26.0", "1": "kubernetes.io/docs/concepts/overview/what-is-kubernetes",}
Use the built-in length
template filter:
{{ post.allLinks|length }} Links
