Class: CloneKit::Rules::Remap

Inherits:
CloneKit::Rule show all
Defined in:
lib/clone_kit/rules/remap.rb

Overview

Utilizes the SharedIdMap stored in Redis to remap original ids to their new cloned values.

Given an original blog post being cloned:
  { title: "Title", author_id: 5 }
And a blog post rule:
  Remap.new(BlogPost, "Author" => "author_id")
And an author record that was cloned from => to:
  { id: 5, name: "Pat" } => { id: 6, name: "Pat" }
The cloned blog post will show the remapped author id:
  { title: "Title", author_id: 6 }

When a remapped id is missing, an error is added to the operation.
