[Task] Widgets should delegate isInitialValue calls as far as possible
Closed, InvalidPublic


In the terms view, the API requests to save changed values are done in the labelview, descriptionview and aliasesview widgets. These, but only these three widgets should have a full implementation of isInitialValue that possibly creates Wikibase-DataModel-JavaScript objects and compares them. All other, higher level widgets should delegate an isInitialValue call to their sub-widgets.

This not only avoids duplicate code. It also avoids creating Wikibase-DataModel-JavaScript objects.

Same for the statements and sitelinks views.

Candidates in the terms section:

  • label-, description- and aliasesview are all fine. All three handle edits itself and propagate them to a changer. Both isInitialValue and value (the later is tracked in T124787) are required for that. The only issue is that the code of the three widgets looks different, but shouldn't.
  • entitytermsforlanguageview wraps a label-, description- and aliasesview. It's isInitialValue forwards nicely.
  • entitytermsforlanguagelistview contains a list of entitytermsforlanguageview widgets. It does not forward isInitialValue but instead does a complicated comparison. This is the main issue why I created this ticket.
  • entitytermsview wraps a single entitytermsforlanguagelistview and forwards nicely.

Statements section:

  • statementview forwards to RankSelector.isInitialValue as well as snakview.isInitialValue, but compares qualifiers and references manually.
  • snaklistview contains a list of snakview widgets, but does not forward.
  • snakview is complicated. Does this count as a "leaf object"? Why is the code so complicated?
  • RankSelector is trivial and fine.
  • referenceview is also complicated and needs more investigation.

Sitelinks section:

  • sitelinkgroupview wraps a single sitelinklistview and forwards nicely.
  • sitelinklistview contains a list of sitelinkview widgets and should forward.
  • sitelinkview is a "leaf object" and fine.

Obsolete now, thanks to Adrian. :-)

Is there still something to do here? If yes it'd be good to clarify what.

isInitialValue does not exist any more.
