Re: Generic view template seems to have empty input

Maybe you should use ListView, not DetailView.

Hi

I have declared a model and the simple views I created are working.

Now I am trying to move to generic views.

So I added in urls.py

    path('book2/<int:pk>/', views.DetailView.as_view(), name='detail'),

And in views.py

class DetailView(generic.DetailView):
    model = Book

And the template is

{% block content %}

  <h1>book List</h1>
  {% if object_list %}
  <ul>
    {% for book in object_list %}
      <li>
        {{ book.author }}
      </li>
    {% endfor %}
  </ul>
  {% else %}
    <p>There are no books in the library.</p>
  {% endif %}      

{% endblock %}

For reference the models.py had been

class Book(models.Model):
    author = models.CharField(max_length=70)

But the result is "There are no books in the library". So it seems that the books list is not transferred to the template to be rendered. Could you help me understand where I have done wrong?

Thank you

Sorry, I mistaked.

You can use Detail view.

DetailView pass your model data, which named "book"(because model name is Book).

Model doesn't list.
