Search
NetBox v3.4 introduced a new global search mechanism, which employs the extras.CachedValue model to store discrete field values from many models in a single table.
SearchIndex
To enable search support for a model, declare and register a subclass of netbox.search.SearchIndex for it. Typically, this will be done within an app's search.py module.
from netbox.search import SearchIndex, register_search
@register_search
class MyModelIndex(SearchIndex):
model = MyModel
fields = (
('name', 100),
('description', 500),
('comments', 5000),
)
A SearchIndex subclass defines both its model and a list of two-tuples specifying which model fields to be indexed and the weight (precedence) associated with each. Guidance on weight assignment for fields is provided below.
Field Weight Guidance
| Weight | Field Role | Examples |
|---|---|---|
| 50 | Unique serialized attribute | Device.asset_tag |
| 60 | Unique serialized attribute (per related object) | Device.serial |
| 100 | Primary human identifier | Device.name, Circuit.cid, Cable.label |
| 110 | Slug | Site.slug |
| 200 | Secondary identifier | Provider.account, DeviceType.part_number |
| 300 | Highly unique descriptive attribute | CircuitTermination.xconnect_id, IPAddress.dns_name |
| 500 | Description | Site.description |
| 1000 | Custom field default | - |
| 2000 | Other discrete attribute | CircuitTermination.port_speed |
| 5000 | Comment field | Site.comments |
