Variable routing

Use specific values in URL positions as variables

# django_intro/urls.py
path('hi/<str:name>/', views.hi),
path('add/<int:a>/<int:b>/', views.add),

2. views.py

# pages/views.py
def hi(request, name):
    context = {
        'name':name
    }
    return render(request, 'hi.html', context)

3. template

<!-- pages/templates/hi.html -->
<h1>
 Hi, {{name}}
</h1>



DTL (Django Template Language)

Template files (HTML) can be structured using Django template language!


  • Django's template language is designed to strike a balance between power and ease.
  • It's designed to feel comfortable to those used to working with HTML.

Basic syntax

1. Output {{ }}

{{ name }}
{{ menu.0 }}

2. Syntax {% %}

{% for option in options%}

{% endfor %}
