Device Link Providers
A device link provider is a subscriber interface that gives a hook for adding context-specific html links (for example, the device links on the Device Details page). Zenpacklib provides a simple class to search the global catalog, device class catalog, or a device local catalog that match a specific query.
To search the global catalog, set global_search to true. If the catalog you wish to search is in a specific device class, set global_search to false and specify the class name with device_class. To search a catalog on the local device, simply set global_search to false and do not set device_class. You can use one or more queries to match up devices/components. In the above example, the XenServer provider will search the global device catalog and match any device’s manageIp attribute with the current device’s vm_id attribute.
Device Link Provider Fields
The following fields are valid for a device link provider entry.
|link_title||Title which will appear on the overview page of the type of device or component.||yes||string||(implied from key in link_providers map)|
|global_search||Search the global catalog?||no||boolean||false|
|link_class||Python class on which this provider will apply. Requires full python class name.||no||string|
|device_class||Device class containing the catalog to search.||no||string||None|
|catalog||Catalog name to search for linked devices or components.||no||string|
|queries||Queries to use to match a linked device/component.|
Each query must be in remote:local format, meaning that the catalog search will match a remote attribute with a local attribute. The local search term could also be actual text. Examples: id:manageIp will match the remote id attribute with the local device’s manageIp attribute, and meta_type:ClusterDevice will match the meta_type on a remote device to “ClusterDevice”.
