Django TypeError objects is not iterable

Question

I tried to show a model data in html template in django.

My Model:

class Author(models.Model):
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)
    date_of_birth = models.DateField(blank=True, null=True)
    date_of_death = models.DateField(blank=True, null=True)

    def get_absolute_url(self):
        return reverse('author_detail', args=[str(self.id)])

    class Meta():
        ordering = ['first_name', 'last_name']

    def __str__(self):
        return f'{self.first_name} {self.last_name}'

My View:

def author_detail_view(request, pk):
    author = get_object_or_404(Author, pk=pk)
    return render(request, 'author_detail.html', context={'author_detail': author})

My URL:

 path('author/<int:pk>', views.author_detail_view, name='author_detail')

And My Templates View:
{% extends 'base.html' %}

{% block content %}
<h1>Author Detail</h1>
    {% for author in author_detail %}
<ul>
    <li>Name: {{ author.first_name }} {{ author.last_name }}</li>
    <li>Date of Birth: {{ author.date_of_birth }}</li>
</ul>
    {% endfor %}
{% endblock %}

But the probelem is, it shoing error that :

TypeError at /author/2

'Author' object is not iterable

Request Method: GET Request URL: http://127.0.0.1:8000/author/2 Django Version: 2.1.5 Exception Type: TypeError Exception Value:

Answer 1

The author_detail is a single Author object, so it does not make sense to iterate over it. What would be the elements over which you can iterate?

You can thus render it like:

{% extends 'base.html' %}

{% block content %}
<h1>Author Detail</h1>
<ul>
    <li>Name: {{ author_detail.first_name }} {{ author_detail.last_name }}</li>
    <li>Date of Birth: {{ author_detail.date_of_birth }}</li>
</ul>
{% endblock %}
