Query().WithAll()

[niondir]

When loading one entity and changing some value, the store.Update() method will delete all relations that are not loaded. Therefore one has to explicitly call all With**() methods.

If there isn't some other way to load an entity with all relations, or to save an entity without setting all relation to null I would suggest some method New**Query().WithAll() to load all related entities as well.

Relations being deleted when set to nil is actually a bug and not expected behaviour, as seen in related issues (#211). This should have been fixed with #214, but for some reason it's back to haunt us. I guess we'll need to wait for a fix.

As a workaraound, I just feed Update() the name of the fields I want to update explicitly.

You might want to edit the title to reflect the actual bug.

Last but not least, as setting the relation to nil won't actually delete the relationship when this is fixed, I've opened an issue (#219) to discuss if a set of functions to delete relations without touching the actual objects is something worth implementing (which I think it is).

Querying all relationships at once is probably a bad idea on most cases, so it makes no sense to me to expose this functionality that easy. Users willing to do this can easily chain all WithTYPE functions.

It's definitely more about the saving part that must not set the not queried relations to nil.

The issue you mention (#211) has already been fixed (#214).
