Stores a string in the database.

A built-in type that can be referenced via :string.

By default, values are trimmed and empty values are set to nil. You can use the allow_empty? and trim? constraints to change these behaviors.

Constraints

• :max_length - Enforces a maximum length on the value

• :min_length - Enforces a minimum length on the value

• :match - Enforces that the string matches a passed in regex

• :trim? - Trims the value. The default value is true.

• :allow_empty? - If false, the value is set to nil if it's empty. The default value is false.
