#rename_field(dirty_key, opts = {}) ⇒ Object

Given a string, convert it using #easy_name

  • if the rename table does not exist, return the converted string

  • if the rename table exists, and has an entry for that converted value

    • if the entry is a token, return the table’s token entry

    • if the entry is true, then just tokenize the converted string

    • if the entry is false, then pass through the converted string

    • otherwise, complain about the invalid value

  • if the rename table exists, and does NOT have an entry

    • return the string
