Templates

Templates are used to render HTML content generated from a set of context data. NetBox provides a set of built-in templates suitable for use in plugin views. Plugin authors can extend these templates to minimize the work needed to create custom templates while ensuring that the content they produce matches NetBox's layout and style. These templates are all written in the Django Template Language (DTL).

Template File Structure

Plugin templates should live in the templates/<plugin-name>/ path within the plugin root. For example if your plugin's name is my_plugin and you create a template named foo.html, it should be saved to templates/my_plugin/foo.html. (You can of course use subdirectories below this point as well.) This ensures that Django's template engine can locate the template for rendering.

Standard Blocks

The following template blocks are available on all templates.

Name	Required	Description
`title`	Yes	Page title
`content`	Yes	Page content
`head`	-	Content to include in the HTML `<head>` element
`footer`	-	Page footer content
`footer_links`	-	Links section of the page footer
`javascript`	-	Javascript content included at the end of the HTML `<body>` element

Note

For more information on how template blocks work, consult the Django documentation.

Base Templates

layout.html

Path: base/layout.html

NetBox provides a base template to ensure a consistent user experience, which plugins can extend with their own content. This is a general-purpose template that can be used when none of the function-specific templates below are suitable.

Blocks

Name	Required	Description
`header`	-	Page header
`tabs`	-	Horizontal navigation tabs
`modals`	-	Bootstrap 5 modal elements

Example

An example of a plugin template which extends layout.html is included below.

{% extends 'base/layout.html' %}

{% block header %}
  <h1>My Custom Header</h1>
{% endblock header %}

{% block content %}
  <p>{{ some_plugin_context_var }}</p>
{% endblock content %}

The first line of the template instructs Django to extend the NetBox base template, and the block sections inject our custom content within its header and content blocks.

Note

Django renders templates with its own custom template language. This is very similar to Jinja2, however there are some important distinctions of which authors should be aware. Be sure to familiarize yourself with Django's template language before attempting to create new templates.

Filters

The following custom template filters are available in NetBox.

Info

These are loaded automatically by the template backend: You do not need to include a {% load %} tag in your template to activate them.

`bettertitle(value)`

Alternative to the builtin title(). Ensures that the first letter of each word is uppercase but retains the original case of all others.

`content_type(model)`

Return the ContentType for the given object.

`content_type_id(model)`

Return the ContentType ID for the given object.

`linkify(instance, attr=None)`

Render a hyperlink for an object with a get_absolute_url() method, optionally specifying the name of an attribute to use for the link text. If no attribute is given, the object's string representation will be used.

If the object has no get_absolute_url() method, return the text without a hyperlink element.

`meta(model, attr)`

Return the specified Meta attribute of a model. This is needed because Django does not permit templates to access attributes which begin with an underscore (e.g. _meta).

Parameters:

Name	Type	Description	Default
`model`		A Django model class or instance	required
`attr`		The attribute name	required

`placeholder(value)`

Render a muted placeholder if the value equates to False.

`render_json(value)`

Render a dictionary as formatted JSON. This filter is invoked as "json":

`render_markdown(value)`

Render a string as Markdown. This filter is invoked as "markdown":

{{ md_source_text|markdown }}

`render_yaml(value)`

Render a dictionary as formatted YAML. This filter is invoked as "yaml":

`split(value, separator=',')`

Wrapper for Python's split() string method.

Parameters:

Name	Type	Description	Default
`value`		A string	required
`separator`		String on which the value will be split	`','`

`tzoffset(value)`

Returns the hour offset of a given time zone using the current time.

Name	Description	Default
`value`	The value to be displayed within the badge	required
`bg_color`	Background color CSS name	`None`
