# Madmin ### 🛠 A robust Admin Interface for Ruby on Rails apps [![Build Status](https://github.com/excid3/madmin/workflows/Tests/badge.svg)](https://github.com/excid3/madmin/actions) [![Gem Version](https://badge.fury.io/rb/madmin.svg)](https://badge.fury.io/rb/madmin) Why another Ruby on Rails admin? We wanted an admin that was: * Familiar and customizable like Rails scaffolds (less DSL) * Supports all the Rails features out of the box (ActionText, ActionMailbox, has_secure_password, etc) * Stimulus / Turbolinks / Hotwire ready ![Madmin Screenshot](docs/images/screenshot.png) _We're still working on the design!_ ## Installation Add `madmin` to your application's Gemfile: ```bash bundle add madmin ``` Then run the madmin generator: ```bash rails g madmin:install ``` This will install Madmin and generate resources for each of the models it finds. ## Resources Madmin uses `Resource` classes to add models to the admin area. ### Generate a Resource To generate a resource for a model, you can run: ```bash rails g madmin:resource ActionText::RichText ``` ## Configuring Views The views packaged within the gem are a great starting point, but inevitably people will need to be able to customize those views. You can use the included generator to create the appropriate view files, which can then be customized. For example, running the following will copy over all of the views into your application that will be used for every resource: ```bash rails generate madmin:views ``` The view files that are copied over in this case includes all of the standard Rails action views (index, new, edit, show, and _form), as well as: * `application.html.erb` (layout file) * `_javascript.html.erb` (default JavaScript setup) * `_navigation.html.erb` (renders the navigation/sidebar menu) As with the other views, you can specifically run the views generator for only the navigation or application layout views: ```bash rails g madmin:views:navigation # -> app/views/madmin/_navigation.html.erb rails g madmin:views:layout # Note the layout generator includes the layout, javascript, and navigation files. # -> app/views/madmin/application.html.erb # -> app/views/madmin/_javascript.html.erb # -> app/views/madmin/_navigation.html.erb ``` If you only need to customize specific views, you can restrict which views are copied by the generator: ```bash rails g madmin:views:index # -> app/views/madmin/application/index.html.erb ``` You can also scope the copied view(s) to a specific Resource/Model: ```bash rails generate madmin:views:index Book # -> app/views/madmin/books/index.html.erb ``` ## Custom Fields You can generate a custom field with: ```bash rails g madmin:field Custom ``` This will create a `CustomField` class in `app/madmin/fields/custom_field.rb` And the related views: ```bash # -> app/views/madmin/fields/custom_field/_form.html.erb # -> app/views/madmin/fields/custom_field/_index.html.erb # -> app/views/madmin/fields/custom_field/_show.html.erb ``` You can then use this field on our resource: ```ruby class PostResource < Madmin::Resource attribute :title, field: CustomField end ``` ## Authentication You can use a couple of strategies to authenticate users who are trying to access your madmin panel: [Authentication Docs](docs/authentication.md) ## 🙏 Contributing This project uses Standard for formatting Ruby code.
