Graylog2
first draft of getting a related identifier
Description
Just a draft for now.
Motivation and Context
When using the entity table, we can define EntityAttributes, which allow us to specify the related collection and the relatedProperty (the value that should be displayed in the filter options).
The issue is that, e.g. inputs do not reference the node by its object ID, but instead by a UUID node_id column. As a result, when selecting one of the provided filter options, the filter returns no data because the relationship is based on the wrong identifier.
It would be useful to have the ability to specify which column or field should be used to relate the entries, rather than assuming the default object ID.
Another issue is that sometimes we don’t store a human-readable title in the database that lets users easily identify the entity. For example, nodes are identified by a combination of the short node_id and the host name, since the host name alone may be shared. After talking to Linus, there is a filter renderer, we can use utilize that to display the short names
