Tera Tags and Filters

Django-like Tags (syntactic sugar)

Tag	Transformed into	Description
`{% static "..." %}`	`{{ "..." \| static }}` (+ `integrity` / `crossorigin` in production)	Static file URL, with its SRI fingerprint outside dev
`{% runique_static "..." %}`	same, Runique's static folder	Files Runique provides (admin, auth, `js/csrf.js`)
`{% media "..." %}`	`{{ "..." \| media }}`	Media file URL
`{% csrf %}`	`{% include "csrf.html" %}`	Hidden CSRF field
`{% messages %}`	`{% include "message.html" %}`	Display flash messages
`{% csp %}`	`{% include "csp.html" %}`	CSP nonce attribute
`{% link "name" %}`	`{{ link(link='name') }}`	Named route URL
`{% form.xxx %}`	`{{ xxx \| form }}`	Full form rendering
`{% form.xxx.field %}`	`{{ xxx \| form(field='field') }}`	Single field rendering
`{% form.xxx.js %}`	`{{ xxx \| form(field='js') }}`	Form JS scripts (field-by-field rendering)

The form filter declares is_safe() — its HTML is emitted unescaped, \| safe is unnecessary.

Tera Filters

Filter	Description
`static`	App static URL prefix
`media`	App media URL prefix
`form`	Render full form or specific field
`csrf_field`	Generate a hidden CSRF input
`markdown`, `sanitize`	HTML rendered from Markdown / cleaned HTML (ammonia), not escaped

Runique also registers utility filters (humanize, slugify, format_date, filesizeformat, mask, plaintext, striptags, urlencode…): see Filters.

Tera Functions

Function	Description
`link(link='...')`	Named URL resolution

In context

The tags combine in a real template:

{% extends "base.html" %}

{% block content %}
  <link rel="stylesheet" href="{% static "css/contact.css" %}">

  {% messages %}

  <form method="post" action="{% link "contact" %}">
    {% form.contact_form %}
    <button type="submit">Send</button>
  </form>

  <img src="{% media avatar %}" alt="avatar">
{% endblock %}

{% static %} / {% media %} accept a string literal or a Tera variable (avatar above). See Django-like tags for the details of each tag.
