Overview

Active Model Type Boolean

A class that behaves like a boolean type, including rules for coercion of user input.

Coercion

Values set from user input will first be coerced into the appropriate ruby type. Coercion behavior is roughly mapped to Ruby’s boolean semantics.

  • “false”, “f” , “0”, 0 or any other value in FALSE_VALUES will be coerced to false

  • Empty strings are coerced to nil

  • All other values will be coerced to true
