Slide 5 [00:18 | 01:00]
------------
**What is a Django Template**
  - We have hardcoded the output in the view
  - What if we want the displayed html to change dynamically?
    - Use a 'template' HTML file
  - Template HTML files contain Django template tags that act like variables
  - Django replaces these tags in the HTML file with dynamic data obtained from views

 Demonstration [04:00 | 05:00]
----------------
**How to create a template**

  - Create a directory called *templates* in blog directory (/blog/templates)
    - cd blogs
    - mkdir templates
  - Create a directory called *blog* within the *templates* directory
    - cd templates
    - mkdir blog
    
In this directory create an *blogs.html* file and add the below code
  
    # /blog/templates/blog/blogs.html
    {% if articles %}
        <ul>
        {% for article in articles %}
            <li>{{ article.title }} | Blog: {{ article.blog.name}}</li>
        {% endfor %}
        </ul>
    {% else %}
        <p>No Blog articles are available.</p>
    {% endif %}

  - We created a django template using an HTML file
  - The Django templates give the user limited programming logic capabilities like variables, if-else & for loops

This is an if-else statement in Django templates
      
      {% if %}
        ...
      {% else %}
        ...
      {% endif %}
      
This is a for loop
      
      {% for var in my_list %}
        ...
      {% endfor %}
      
  - variables and objects are represented as {{ my_variable }}
  - *Narrator's note* We will discuss more about Django templating later in the series 

Demonstration [03:00 | 08:00]
----------------
Now let's modify the blog/views.py as follows
    
    from django.http import HttpResponse
    from django.shortcuts import render
    
    
    from .models import Blog, Article

    def index(request):
        article_list = Articles.objects.all()
        context = {'article_list': article_list}
        return render(request, 'blog/index.html', context)

  - Run the django server
  - Access the link localhost:8000/blogs/
