Django + Jinja2
Django Templates • The Django Template Language • How Django
loads templates
Django Templates • The Django Template Language • How Django
loads templates DTL
<ul> {% for user in users.all %}
<li> <a href="{{ user.url }}"> {{ user.username|capitalize }} </a> </li> {% endfor %} </ul>
<ul> {% for user in users.all %}
<li> <a href="{{ user.url }}"> {{ user.username|capitalize }} </a> </li> {% endfor %} </ul> (Template) Tag
<ul> {% for user in users.all %}
<li> <a href="{{ user.url }}"> {{ user.username|capitalize }} </a> </li> {% endfor %} </ul> Variable
<ul> {% for user in users.all %}
<li> <a href="{{ user.url }}"> {{ user.username|capitalize }} </a> </li> {% endfor %} </ul> Variable + Filter
The DTL • Simple syntax with few rules • Lightweight
extensions • Self-contained
But… • Awkward DSL • No scoped functions • Slow
with frequent rendering
Django 1.8 • django.template • django.template.backends
TEMPLATE_CONTEXT_PROCESSORS TEMPLATE_DEBUG TEMPLATE_STRING_IF_INVALID TEMPLATE_DIRS TEMPLATE_LOADERS The
Language The System
TEMPLATE_CONTEXT_PROCESSORS TEMPLATE_DEBUG TEMPLATE_STRING_IF_INVALID TEMPLATE_DIRS TEMPLATE_LOADERS The
Language The System
TEMPLATES = [ {
'BACKEND': '...', 'DIRS': [], 'OPTIONS': { 'context_processors': [...], 'debug': False, 'string_if_invalid': '', }, }, ] Language-specific Setup Template-loading Setup
None
Jinja2 • Armin Ronacher (aka mitsuhiko) • Inspired by the
DTL • Standalone library • More programmer-friendly
<ul> {% for user in users.all() %}
<li> <a href="{{ user.url }}"> {{ user.username.toupper() }} </a> </li> {% endfor %} </ul> Function calling
<ul> {% for user in users.get_friends(me) %}
<li> <a href="{{ user.url }}"> {{ user.username.toupper() }} </a> </li> {% endfor %} </ul>
Settings for Jinja2 { 'BACKEND': (
'django.template.backends.' 'jinja2.Jinja2'), 'DIRS': [], 'APP_DIRS': True, },

demoapp ├── jinja2 │ └── a_jinja2_template.html ├── models.py ├── templates
│ └── a_django_template.html ├── urls.py └── views.py Configurable (not recommended)
Jinja2 for Django • Auto-escape on • Custom template loader
• Debug enhancements • Auto-reload • Undefined raises exceptions
But • Jinja2 is not built (just) for Web •
Web-related functionalities • Django internals
{% url 'pages:page' name=page_name %} {% static 'base/css/site.min.css' %}
{% trans 'This is my website!' %} {% csrf_token %}

{ 'BACKEND': ('django.template.backends.'
'jinja2.Jinja2'), 'DIRS': [], 'APP_DIRS': True, 'OPTIONS': { 'extensions': [ 'jdj_tags.extensions.DjangoStatic', 'jdj_tags.extensions.DjangoI18n', ] }, },
Jinja2 vs DTL • Functions vs template tags • Methods
vs filters • Extensions are loaded by project
The Flask Way • {% url_for(endpoint, **kwargs) %} • Endpoint
'static' • {% get_flashed_messages(...) %} • I18n API (already pretty similar) • {{ csrf_token() }}
To boldly go where no one has gone before.
