Retrieve info from many-to-many relationship in django temaplate - django

Question

I am creating a blog and have a many-to-many relationship between the posts and categories.
class Category(models.Model):
title = models.CharField(max_length=255)
slug = models.SlugField()
def __str__(self):
return self.title
class Post(models.Model):
title = models.CharField(max_length=255)
subtitle = models.CharField(max_length=255,null=True,blank=True)
published_date = models.DateTimeField(auto_now_add=True)
draft = models.BooleanField(default=True)
body = RichTextField(config_name='blog')
slug = models.SlugField()
categories = models.ManyToManyField(Category)
featured = models.BooleanField(default=False)
I am trying to retrieve the the list of categories associated to an individual post within the template so I can display those category titles at the bottom of the post.
Here is the template code which displays the posts properly but not the categories.
{% for post in blog_posts %}
<div class="post">
<div class="date">
{{post.published_date|date:"M"}}
<span class="day">{{post.published_date|date:"d"}}</span>
<span>{{post.published_date|date:"Y"}}</span>
</div>
<div class="entry">
<div class="page-header">
<h2 class="post-title">{{post.title}}</h2>
</div>
<blockquote>
<p><strong>{{post.subtitle}}</strong></p>
</blockquote>
<p>{{post.body|safe}}</p>
<div class="well well-small">
<i class="icon-th-list "></i> Categories:LIST CATEGORIES HERE
</div>
</div> <!--entry div-->
</div><!--post div-->
{% endfor %}
Does anyone have thoughts on how I could retrieve the categories for a specific post? I greatly appreciate the time and expertise.

Answer 1

You can access the categories with this
{% for category in post.categories.all %}
{{ category.title }}
{% endfor %}
I also recommend adding .prefetch_related('categories') to the queryset in your view to reduce the number of sql queries.
