Templates

A Django template is an HTML file with special tags: {{ variable }} prints a value, and {% tag %} handles logic like loops and conditionals.

Example: looping and handling the empty case

{# blog/post_list.html #}
<h1>Blog Posts</h1>
<ul>
  {% for post in posts %}
    <li>{{ post.title }}</li>
  {% empty %}
    <li>No posts yet.</li>
  {% endfor %}
</ul>

Renders a bulleted list of every post's title, or "No posts yet."
if the posts list is empty.

The view's context dictionary (that {'posts': posts} from the Views lesson) is exactly what fills these placeholders in — {{ post.title }} reads the title attribute off each Post object the view passed in. {% empty %} is a small but genuinely useful detail — it renders only when the loop had nothing to iterate over at all, sparing you from writing a separate {% if %} just to handle an empty list gracefully.
