This plugin extends the default issue relation functionality in Redmine. When adding multiple issues as a relation via a comma-separated string (e.g., 12, 13, 15), Redmine natively links the base issue to each of these targets. This plugin automatically extends this behavior by cross-relating all the newly provided issues with each other.

Features

Automatically creates cross-relations for comma-separated issue IDs.
Gracefully handles validation failures (e.g., missing issues, cross-project restrictions).
Lightweight, using standard Rails ActiveSupport::Concern to patch the controller without overriding core files.

Compatibility

Plugin Version	Redmine Version
2026.8.0+	Redmine 5.x

Installation

1. Clone the Plugin

Install the plugin into your Redmine plugins directory.

cd /path/to/redmine/plugins  
git clone https://github.com/rickbarrette/redmine_recursive_relations.git  
cd redmine_recursive_relations  

# Optional but recommended: Checkout a specific tagged release for stability
git checkout <tag>

2. Restart Redmine

Because this plugin patches the core controller, no database migrations are required. Simply restart your Redmine application server (e.g., Puma, Passenger, or Unicorn) so the plugin and hooks are loaded.

Usage

Once installed and the server is restarted, there is no configuration needed.
