Description
The Where() method is only available for Update and Delete, not for UpdateOne and DeleteOne, but it would be quite useful to be able to use it on those simply as a way of specifying extra constraints. For example, let's say that you have two entities, A and B, where A has an edge to B but that edge is unique the other direction. The user wants to update a B belonging to a certain A. Currently, the only way to ensure that the user's input is correct for both IDs is to use an Update, such as
n, err := entc.B.Update().
Where(b.ID(bid)).
Where(b.HasAWith(a.ID(aid))).
SetSomeField(something).
Save(ctx)and then manually check if n is in fact one. It would be convenient to be able to do
b, err := entc.B.UpdateOneID(bid).
Where(b.HasAWith(a.ID(aid))).
SetSomeField(something).
Save(ctx)instead and let it properly fail with a ent.IsNotFound(err) == true error if nothing with that condition exists. Not to mention that this will return the updated entity, too.
