Plone Add-On for alias contents 🚀

This is a Plone Add-On that allows to create content aliases.

Features

There is a new content type called ReferenceContent, which can be related to any other content on the site.

When a ReferenceContent refers to another content item, it will proxy the original content’s features:

• Data (both in catalog and REST API serializers). When the referenced content is updated, the proxy automatically inherits those changes.
• Workflow / review state. When the referenced content changes its state, the proxy reflects this transition as well.

By default, in a ReferenceContent item you can only edit the referenced item and its short name (id). By default, the short name is taken from the original content.

All data is proxied from the original content. However, if you need to add extra data to ReferenceContent, you can enable additional behaviors.

In that case, the fields provided by these behaviors are appended to the proxy’s data. If there is a field in common with the referenced content (for example, if you add the plone.categorization behavior), the field defined in the proxy always takes precedence.

Quick Start 🏁

Prerequisites ✅

• An operating system that runs all the requirements mentioned.
• uv
• nvm
• Node.js and pnpm 24
• Make
• Git
• Docker (optional)

Installation 🔧

1. Clone this repository, then change your working directory.

   git clone [email protected]:collective/collective-referencecontent.git
   cd collective-referencecontent

2. Install this code base.

   make install

Fire Up the Servers 🔥

1. Create a new Plone site on your first run.

   make backend-create-site

2. Start the backend at http://localhost:8080/.

   make backend-start

3. In a new shell session, start the frontend at http://localhost:3000/.

   make frontend-start

Voila! Your Plone site should be live and kicking! 🎉

Local Stack Deployment 📦

Deploy a local Docker Compose environment that includes the following.

• Docker images for Backend and Frontend 🖼️
• A stack with a Traefik router and a PostgreSQL database 🗃️
• Accessible at http://collective-referencecontent.localhost 🌐

Run the following commands in a shell session.

make stack-create-site
make stack-start

And... you're all set! Your Plone site is up and running locally! 🚀

Project structure 🏗️

This monorepo consists of the following distinct sections:

• backend: Houses the API and Plone installation, utilizing pip instead of buildout, and includes a policy package named collective.referencecontent.
• frontend: Contains the React (Volto) package.
• devops: Encompasses Docker stack, Ansible playbooks, and cache settings.
• docs: Scaffold for writing documentation for your project.

Why this structure? 🤔

• All necessary codebases to run the site are contained within the repository (excluding existing add-ons for Plone and React).
• Specific GitHub Workflows are triggered based on changes in each codebase (refer to .github/workflows).
• Simplifies the creation of Docker images for each codebase.
• Demonstrates Plone installation/setup without buildout.

Code quality assurance 🧐

To check your code against quality standards, run the following shell command.

make check

Format the codebase

To format and rewrite the code base, ensuring it adheres to quality standards, run the following shell command.

make format

Section	Tool	Description	Configuration
backend	Ruff	Python code formatting, imports sorting	backend/pyproject.toml
backend	zpretty	XML and ZCML formatting	--
frontend	ESLint	Fixes most common frontend issues	frontend/.eslintrc.js
frontend	prettier	Format JS and Typescript code	frontend/.prettierrc
frontend	Stylelint	Format Styles (css, less, sass)	frontend/.stylelintrc

Formatters can also be run within the backend or frontend folders.

Linting the codebase

or lint:

make lint

Section	Tool	Description	Configuration
backend	Ruff	Checks code formatting, imports sorting	backend/pyproject.toml
backend	Pyroma	Checks Python package metadata	--
backend	check-python-versions	Checks Python version information	--
backend	zpretty	Checks XML and ZCML formatting	--
frontend	ESLint	Checks JS / Typescript lint	frontend/.eslintrc.js
frontend	prettier	Check JS / Typescript formatting	frontend/.prettierrc
frontend	Stylelint	Check Styles (css, less, sass) formatting	frontend/.stylelintrc

Linters can be run individually within the backend or frontend folders.

Internationalization 🌐

Generate translation files for Plone and Volto with ease:
