Overview

Form rows in, the variables: list PublishFormulaVersion takes out.

Two things here are not cosmetic. First, an HTML form can post repeated fields either as an array (version[variables][][name]) or as an index-keyed hash (version[variables][0][name]); the second is what fields_for emits and the only one that survives a row whose checkbox is the sole differing field, so both are accepted.

Second, required. CastVariableAttributes treats anything that is not literally false as true, and an unchecked Rails checkbox posts the string "0" — which would sail through as required: true and turn an optional variable into one that raises MissingVariableError at calculation time. The string has to become a real boolean before it gets anywhere near the core gem.
