Not showing bio tag in Django?

Question

I’m working on a blog page, and I’m creating page about authors but it doesn’t work to load bio (short description). I don’t know why it wasn’t working, please see code below:

this is author_detail.html

<p>Bio: {{ author.bio }}</p>

this is views.py

def author_detail(request, slug):
    user = User.objects.get(username=slug)
    author = Author.objects.get(user=user)
    posts = Post.objects.filter(author=user)
    return render(request, 'author_detail.html', {'author': user, 'posts': posts})

this is models.py

class Author(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    bio = models.TextField(max_length=500, blank=True, default='', help_text='Enter a short description about yourself.')
    slug = models.SlugField(unique=True)

    def save(self, *args, **kwargs):
        if not self.slug:
            self.slug = self.user.username.lower().replace(' ', '-')
        super().save(*args, **kwargs)
        if not self.bio:
            self.bio = "This author hasn't added a bio yet."
        
    def __str__(self):
        return self.user.username

if I add print('author.bio') it gives me in the terminal the bio, but I don’t know why it doesn’t show up in (html) page… Any idea?

As already described by kamran890 in the above comment.

It should be author in context not user so:

def author_detail(request, slug):
    user = User.objects.get(username=slug)
    author = Author.objects.get(user=user)
    posts = Post.objects.filter(author=user)
    return render(request, 'author_detail.html', {'author': author, 'posts': posts})

If you want to retrieve first_name from author instance then use {{author.user.first_name}}.
