class ActiveModel::Type::Boolean

  • All other values will be coerced to true
    - Empty strings are coerced to nil
    - “false”, “f” , “0”, 0 or any other value in FALSE_VALUES will be coerced to false
    Coercion behavior is roughly mapped to Ruby’s boolean semantics.
    Values set from user input will first be coerced into the appropriate ruby type.
    === Coercion
