Tables
NetBox employs the django-tables2
library for rendering dynamic object tables. These tables display lists of objects, and can be sorted and filtered by various parameters.
NetBoxTable
To provide additional functionality beyond what is supported by the stock Table
class in django-tables2
, NetBox provides the NetBoxTable
class. This custom table class includes support for:
- User-configurable column display and ordering
- Custom field & custom link columns
- Automatic prefetching of related objects
It also includes several default columns:
pk
- A checkbox for selecting the object associated with each table row (where applicable)id
- The object's numeric database ID, as a hyperlink to the object's view (hidden by default)actions
- A dropdown menu presenting object-specific actions available to the user
Example
# tables.py
import django_tables2 as tables
from netbox.tables import NetBoxTable
from .models import MyModel
class MyModelTable(NetBoxTable):
name = tables.Column(
linkify=True
)
...
class Meta(NetBoxTable.Meta):
model = MyModel
fields = ('pk', 'id', 'name', ...)
default_columns = ('pk', 'name', ...)
Table Configuration
The NetBoxTable class features dynamic configuration to allow users to change their column display and ordering preferences. To configure a table for a specific request, simply call its configure()
method and pass the current HTTPRequest object. For example:
table = MyModelTable(data=MyModel.objects.all())
table.configure(request)
This will automatically apply any user-specific preferences for the table. (If using a generic view provided by NetBox, table configuration is handled automatically.)
Columns
The table column classes listed below are supported for use in plugins. These classes can be imported from netbox.tables.columns
.
BooleanColumn (Column)
Custom implementation of BooleanColumn to render a nicely-formatted checkmark or X icon instead of a Unicode character.
ChoiceFieldColumn (Column)
Render a model's static ChoiceField with its value from get_FOO_display()
as a colored badge. Background color is
set by the instance's get_FOO_color() method, if defined.
ColorColumn (Column)
Display an arbitrary color value, specified in RRGGBB format.
ColoredLabelColumn (TemplateColumn)
Render a related object as a colored label. The related object must have a color
attribute (specifying
an RRGGBB value) and a get_absolute_url()
method.
ContentTypeColumn (Column)
Display a ContentType instance.
ContentTypesColumn (ManyToManyColumn)
Display a list of ContentType instances.
MarkdownColumn (TemplateColumn)
Render a Markdown string.
TagColumn (TemplateColumn)
Display a list of Tags assigned to the object.
TemplateColumn (TemplateColumn)
Overrides django-tables2's stock TemplateColumn class to render a placeholder symbol if the returned value is an empty string.
