# Redmine Subtask Field Copier

A lightweight plugin for **Redmine** that automatically copies fields from a parent issue into a newly created subtask, saving time and reducing manual data entry.

## Features

* Automatically copies all Custom Field values from the parent issue to the new subtask.
* **Seamless Integrations:** Out-of-the-box support for the `redmine_qbo` and `redmine_qbo_vehicles` plugins (automatically copies Customer, Estimate and Vehicle fields).

## Installation

### 1. Clone the Plugin

Install the plugin into your Redmine `plugins` directory.

```bash
cd /path/to/redmine/plugins  
git clone https://github.com/rickbarrette/subtask_field_copier.git  
cd subtask_field_copier  

# 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. Simply navigate to an existing issue, click the **Add Subtask** link, and the new subtask form will automatically be pre-populated with the parent issue's data.
