Add an isComputed method to field handlers

Open on Drupal.org →

Created on 3 October 2014, about 10 years ago

Updated 29 August 2024, 4 months ago

Problem/Motivation

All field handlers that provide things like links do not want to do anything to affect the views query. So the current 'API' for this is just overriding the query() method and leaving it empty, so the parent does not get called. It would be nicer to make this explicit, like click sort is declared.

Additionally, other Views plugins need to be able to determine whether or not a field handler influences the query, since those plugins might rely on the fact that the field handler adds one or more fields to the query. See #2401953: Database exception for View with Combined field filter with fields with no query alias → for an example of this scenario.

Task because computed fields always existed, at least on a implicit level.

Proposed resolution

Add an isComputed() method to FieldPluginBase, this would default to false. Handlers could then either add 'computed' to the views data implementation using the handler or just overriding the method. The base query method can then check this property.

Remaining tasks

- Address issue comments by updating issue summary about why issue is in Needs work status and add these to Remaining tasks.
- Add a merge request for 11.x branch so that tests run and test-only job can run.

Is anyone ever going to commit this ten year old issue? How can we get more attention on this issue?

We can start by creating an issue fork and merge request for 11.x, and the issue is in Needs work based on comments above. Once in Needs review, it might help to add this to the Needs Review Queue Initiative or discuss in an appropriate Slack channel.

I removed the beta table adjusting the issue summary to compensate because that was something we did specifically for Drupal 8 and no longer applies.
