Instance Method Details

#setting_accessor(setting_name, options = {}) ⇒ Object

Generates a new accessor (=getter and setter) for the given setting

Options Hash (options):

  • :fallback (Symbol, Object) — default: nil —

    If set to :default, the getter will return the setting’s default value if no own value was specified for this record

    If set to :global, the getter will try to find a global setting if no record specific setting was found

    If set to another value, this value is used by default

    If not set at all or to nil, the getter will only search for a record specific setting and return nil if none was specified previously.
