Module: Plutonium::StructuredInputs::ParamCleaner

Defined in:
lib/plutonium/structured_inputs/param_cleaner.rb

Overview

Normalises an extracted structured-input value before it is stored.

The form’s ‘extract_input` already yields a `Hash` (single) or an `Array<Hash>` (repeater), so the only work left is to symbolise keys and, for repeaters, drop rows the user left entirely blank.

Class Method Details

.call(value, repeat:) ⇒ Hash+

Parameters:

  • value (Hash, Array, nil) —

    the extracted param for this input

  • repeat (Boolean, Integer) —

    truthy => array (repeater), else hash

Returns:

  • (Hash, Array<Hash>)
