formtastic_tristate_radio 0.2.3

Have 3-state radiobuttons instead of a 2-state checkbox for your Boolean columns which can store NULL. What the gem does? 1. Provides a custom Formtastic input type `:tristate_radio` which renders 3 radios (“Yes”, “No”, “Unset”) instead of a checkbox (only where you put it). 1. Teaches Rails recognize `"null"` and `"nil"` param values as `nil`. See “[How it works](#how-it-works)” ☟ section for technical details on this. 1. Encourages you to add translations for ActiveAdmin “status tag” so that `nil` be correctly translated as “Unset” instead of “False”. Does not change controls, you need to turn it on via `as: :tristate_radio` option. By defenition Boolean values have 2 states: True & False. However, if you store a Boolean value in a database column with no `NOT NULL` restriction, it aquires a 3<sup>d</sup> possible state: `null`. Some may consider this practice questionable — I don’t think so. In real life you always have a case when the answer to your question may be only “yes” or “no”, but you don’t know the answer yet. Using a string type column, storing there `"yes"`, `"no"` and `"unset"` + using a state machine + validations — feels overkill to me.
