Django: Querying Multiple Foreign Keys

django, models, orm, python

Solution

View:

def index(request):
    posts = Post.objects.filter(active=True)   
    return render(request, 'blog/index.html', {'posts': posts})

Template:

{% for post in posts %}
    <h2><a href="{{ post.get_absolute_url }}">{{ post.title }}</a></h2>
    <p>{{ post.excerpt|truncatewords:30 }}</p>
    <p>Posted by {{ post.user.first_name }} {{ post.user.last_name }}</p>
{% endfor %}

Problem

First off, I'm sure this is a simple question. I'm just getting started with Django and as all beginners do, I thought I'd build a simple blog. I have a simple data model, a Post model that contains with a link to a user via a FK. models.py ``` class Post(TimeStampedActivate): """ A blog post """ title = models.CharField(max_length=255) slug = models.SlugField() excerpt = models.TextField(blank=True) body = models.TextField() publish_at = models.DateTimeField(default=datetime.datetime.now()) created = models.DateTimeField(auto_now_add=True) modified = models.DateTimeField(auto_now=True) active = models.BooleanField(default=False, help_text='Is the blog post active?') user = models.ForeignKey(User, related_name='post_user') def __unicode__(self): return self.title ``` I then want a page that lists all of the Posts alongside the username of the person who created the post. My current view looks like this: views.py ``` def index(request): posts = Post.objects.filter(active=True) user = User.objects.get(id=1) return render(request, 'blog/index.html', {'posts': posts, 'user': user}) ``` My template At present this just displays the users name that matches an ID of 1. ``` {% for post in posts %} <h2><a href="{{ post.get_absolute_url }}">{{ post.title }}</a></h2> <p>{{ post.excerpt|truncatewords:30 }}</p> <p>Posted by {{ user.first_name }} {{ user.last_name }}</p> {% endfor %} ``` How would I modify my views.py file to ensure I get the first and last name of the user responsible for the post?
