Update now creates non-extant entities #139

Closed scruzin closed 4 months ago

scruzin commented 4 months ago

Also, add a helper function, NewEntity, to create a new entity.

Can you take a look @scott97 at why this has broken some tests?

=== RUN   TestUpdateUserForNonExistentEntity
    users_test.go:137: Did not receive expected error when updating non-existent user

I have a test for trying to update a non-existent entity which looks for an error that no longer occurs. In the openfish api clients can supply a partial object that only contains the parts of the entity to update. So if the entity does not exist, we can't create one since not all the information is guaranteed to be supplied by the client. I think it is easily fixable with no changes to the datastore package needed, I'll look into it.

How is this for the update function? Takes an extra argument upsert - update or insert in a single operation 

func (s *CloudStore) Update(ctx context.Context, key *Key, fn func(Entity), dst Entity, upsert bool) error {
    _, err := s.client.RunInTransaction(ctx, func(tx *datastore.Transaction) error {
        err := tx.Get(key, dst)
        if err != nil && !(upsert && err == ErrNoSuchEntity) {
            return err
        }
        fn(dst)
        _, err = tx.Put(key, dst)
        return err
    })
    return err
}

I have tested this, all tests pass now. Downside is that oceantv is going to need changes to its usage of Update, to include the last argument.

We've decided to revert to the original functionality.
