[RUBY] Continuation ・ Active hash that can be handled as data even if it is not in the database ~ Display

Introduction

For how to use ActiveHash, please refer to the previously posted here.

How to retrieve ActiveHash strings

When you want to display the data saved in ActiveHash in the view, only the column name will display the numerical value.

ex)


item.prefecture.name

If you add name after the column name, the character string associated with id will be displayed.
