Class Method Details

.from_hash(permissions) ⇒ Array<Consent::Permission>

Transforms a hash of permissions and views to grant into a collection of Consent::Permission

I.e.:

Permission.from_hash User => { write: :territory }
=> [#<Consent::Permission view: :territory, action: :write, subject: User>]

Permission.from_hash User => { write: :territory, read: :all }
=> [#<Consent::Permission view: :territory, action: :write, subject: User>,]
    #<Consent::Permission view: :all, action: :read, subject: User>]

It also eliminates any invalid permission from the resulting set

I.e.:

Permission.from_hash User => { write: :territory, read: :no_access }, Department: { write: :all }
=> [#<Consent::Permission view: :territory, action: :write, subject: User>,]
    #<Consent::Permission view: :all, action: :write, subject: Department>]
