Pregunta
In my model class Project
, I wish to create projects with a name
. I validate the name like this:
validates :name, :uniqueness => true
I would like the name
for the projects to be unique, only in the scope of a User
. Meaning, a user cannot have multiple projects with the same name, but the projects table may contain multiple projects with the same name, owned by different users.
