Admin generator for redde projects

Installation

  • Add this line to your application's Gemfile and run bundle command:
  gem 'redde'
  • For the first time installation run
rails g redde:layout

This command will generate basic structure for your admin interface.

  • Mound engine in your routes.rb
devise_for :managers, controllers: { registrations: 'managers/registrations' } if defined?(Devise)
mount Redde::Engine, at: '/redde'

It will disable Manager model registration with devise and mount engine.

  • Include layout concern in your ApplicationController
class ApplicationController < ActionController::Base
  include Redde::Layouts
  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception
end
  • Install and run migrations
rake redde:install:migrations
rake db:migrate
  • Include assets in your admin.js and admin.css

admin.js

//= require redde

admin.css

 *= require redde

Scaffold

To generate admin views and controller for a model, enter:

rails g redde:scaffold ModelNames

It will generate empty controller with all needed stuff. If you want to customize it - feel free to override views and controller actions.

If you have position field of integer type in your model, generator will add special column as a hook for sort. You should add POST sort action to you routes:

resources :article_categories do
  post 'sort', on: :collection
end

If you have visible field of boolean type in your model, generator will add small eye column for toggling visiblity

Notice

To customize notice, override method default_notice in controller

Tree sort

If your model have ancestry and position fields, it will be rendered as tree automatically.

UrlGenerator

Redde::UrlGenerator - is a small lib to convert title and id to combine url, used in to_param method.

Usage example:

generator = Redde::UrlGenerator.new(1, 'тестовый заголовок $%##@$@#$')
generator.url
=> '1-testovyy-zagolovok'

Sluggable

Sluggable is used to include into model with permanent slugs (similar to permalink).

Your ActiveRecord model should have slug field and title field.

You can set title field by setting TITLE_FIELD to symbol of method. This method will be used to generate slug. If TITLE_FIELD constant is not set, :title symbol will be used insted.

Usage example:

Book should have title and slug fields.

class Book < ActiveRecord::Base
  TITLE_SYMBOL = :name
  include Redde::Sluggable
  validates :name, presence: true
end

b = Book.new(name: 'Тестовая книга')
b.save
b.slug
=> 'testovaya-kniga'

b.to_param
=> '1-testovaya-kniga'

Photos

You can attach photos to any ActiveRecord model by including

include Redde::WithPhoto

Localization

By default, views in admin interface use I18n for field names and titles. Example:

ru:
  activerecord:
    models:
      article:
        acc: статью
        many: Статьи
        one: Статья
        other: Статьи
      article_category:
        acc: категорию
        many: Категории
        one: Категория
        other: Категории

    attributes:
      article:
        title: Заголовок
        slug: URL
        body: Текст
      article_category:
        title: Заголовок
        position: Позиция
        visible: Отображать на сайте

Index view customization

By default, gem will render view with all fields. You can customize this in two ways:

Array

You can INDEX_COLUMNS array to your model to customize index fields and ther sort order by defining constant inside model

INDEX_COLUMNS = %w(title created_at)

Hash

If you need to add, for example, link to nested model, you can define hash inside model:

class Calculator < ActiveRecord::Base
  INDEX_COLUMNS = {
    name: '',
    hop: ->(item) { ActionController::Base.helpers.link_to("На сайт (#{2 * 2})", Rails.application.routes.url_helpers.root_path(id: item.id)) }
  }
  FORM_COLUMNS = %w(name)
end
