Problem ved hentning af poster med tomt array

I Rails 4 kan du bruge User.where.not(id: []) hvilket vil give dig det rigtige resultat. Det producerer:

SELECT "users".* FROM "users" WHERE (1 = 1)

Desværre User.where('id NOT IN (?)', []) burde være ækvivalent, men det er det ikke. Det giver dig stadig det forkerte resultat:

SELECT "users".* FROM "users" WHERE (id NOT IN (NULL))
