#money(column_names, options = {}) ⇒ Object

Note:

If we have defined a currency column for a record then only the integer column is defined.

Creates one or two columns to represent a Money object in the named table

An integer column for storing Money in its base unit eg. cents for a Dollar denomination and a string for storing its currency name. Can think of it as a persisted or serialized Money object in the database. The integer column is suffixed with ‘_money’ to aid in reflection ie. to find all money columns. Likewise the currency column is suffixed with ‘_currency’ If does not create an individual currency column if a common currency column is defined

Parameters:

  • column_names (Array|Symbol|String) —

    List of money columns to add

Returns:

  • is not important and can change
