Class: Mongory::Converters::ValueConverter

Inherits:
AbstractConverter show all
Defined in:
lib/mongory/converters/value_converter.rb

Overview

ValueConverter transforms query values into a standardized form. It handles arrays, hashes, regex, and basic types, and delegates fallback logic to DataConverter. Used by ConditionConverter to prepare values in nested queries.

  • Arrays are recursively converted
  • Hashes are interpreted as nested conditions
  • Regex becomes a Mongo-style $regex hash
  • Strings and Integers are passed through
  • Everything else falls back to DataConverter

Examples:

Convert a regex

ValueConverter.instance.convert(/foo/) #=> { "$regex" => "foo" }
