Custom Links
Custom links allow users to place arbitrary hyperlinks within NetBox views. These are helpful for cross-referencing related records in external systems. For example, you might create a custom link on the device view which links to the current device in a network monitoring system.
Custom links are created under the admin UI. Each link is associated with a particular NetBox object type (site, device, prefix, etc.) and will be displayed on relevant views. Each link is assigned text and a URL, both of which support Jinja2 templating. The text and URL are rendered with the context variable obj representing the current object.
For example, you might define a link like this:
- Text:
View NMS - URL:
https://nms.example.com/nodes/?name={{ obj.name }}
When viewing a device named Router4, this link would render as:
<a href="https://nms.example.com/nodes/?name=Router4">View NMS</a>
Custom links appear as buttons at the top right corner of the page. Numeric weighting can be used to influence the ordering of links.
Conditional Rendering
Only links which render with non-empty text are included on the page. You can employ conditional Jinja2 logic to control the conditions under which a link gets rendered.
For example, if you only want to display a link for active devices, you could set the link text to
{% if obj.status == 1 %}View NMS{% endif %}
The link will not appear when viewing a device with any status other than "active."
Another example, if you want to only show an object of a certain manufacturer, you could set the link text to:
{% if obj.device_type.manufacturer.name == 'Cisco' %}View NMS {% endif %}
The link will only appear when viewing a device with a manufacturer name of "Cisco."
Link Groups
You can specify a group name to organize links into related sets. Grouped links will render as a dropdown menu beneath a single button bearing the name of the group.
