Relatively minor issue, but in my model I have a localized field with a uniqueness validator.
field :name, type: String, localized: true
validates_uniqueness_of :name
Normally it will query for uniqueness with the following:
`"$or"=>[{"name.en"=>"My name"}]`
But if the input value is empty, it queries with:
`"$or"=>[]`
Which will trigger an error from the DB:
