LesliAdmin is the official account administration engine for the Lesli Framework.

It provides account owners and administrators with a central interface for managing organization settings and shared account data.

• Account details and administrative settings
• Locations and regional configuration
• Currencies and account-level preferences
• User profile administration
• Integration with Lesli users, permissions, and navigation

• Try the online demo
• Run the Docker demo

• A Rails application with Lesli
• SQLite by default, or PostgreSQL when preferred by the host application

Add the engine to the host Rails application and prepare its database:

bundle add lesli_admin
bin/rails db:prepare

Applications using Lesli's standard router mount LesliAdmin automatically at /admin:

# config/routes.rb
Rails.application.routes.draw do
    Lesli::Router.mount(self)
end

If the application does not use the standard Lesli router, mount the engine directly:

# config/routes.rb
Rails.application.routes.draw do
    mount LesliAdmin::Engine => "/admin"
end

Start Rails and visit http://127.0.0.1:3000/admin:

bin/rails server

Clone LesliAdmin into the host application's engines directory:

cd RailsApp
mkdir -p engines
git clone https://github.com/LesliTech/LesliAdmin.git engines/LesliAdmin

Reference the local engine from the host application's Gemfile:

gem "lesli_admin", path: "engines/LesliAdmin"

Install dependencies, prepare the host database, and start Rails:

bundle install
bin/rails db:prepare
bin/rails server

From a complete Lesli development workspace, run the engine test suite from the LesliAdmin directory:

cd engines/LesliAdmin
bin/rails test
