AdminLTE for Rails

This is an attempt to create a reusable gem for AdminLTE theme.

Don't use this gem since it's changing a lot at the moment.

You might be better off using adminlte-rails or adminlte2-rails gem - at least for now.

This gem uses rails-assets-admin-lte gem under the hood. It started out as a container for AdminLTE assets but this is now handled for us by bower package at rails-assets.org.

This gem will probably slowly transform to only include helpers and custom modifications of AdminLTE.

Installation

Add this line to your application's Gemfile:

gem "admin_lte_rails"

And then execute:

$ bundle install

Usage

The easiest way to get started is to generate layout views

rails generate admin_lte_rails:views

Then in your controller define layout 'admin_lte' to use the new theme.

For widgets and their options check out theme's homepage.

Choosing admin theme

By default there no admin theme is used. You should include one from rails-assets-admin-lte gem. In your assets/application.scss add

//= require "admin-lte/skins/skin-blue"

Controller helpers

To get some default REST actions include AdminLteRails::RestControllerConcern in your controller.

class PostsController < AdminController
  include AdminLteRails::RestControllerConcern
end

You will probably override default actions for more complex actions.

View helpers

You can use nav_link_to(text, url, icon=nil) for generating links for sidebar.

Sidebar example

= content_for :admin_sidebar do
  %ul.sidebar-menu
    %li.header Products
    = nav_link_to "Products", [:admin, :products], "fa-bicycle"
    = nav_link_to "Categories", [:admin, :categories], "fa-list"
    = nav_link_to "Brands", [:admin, :brands], "fa-heart"
    = nav_link_to "Tags", [:admin, :tags], "fa-tags"
    %li.header Content
    = nav_link_to "Pages", [:admin, :pages], "fa-files-o"
    = nav_link_to "Blog posts", [:admin, :posts], "fa-newspaper-o"

Topbar example

= content_for :admin_topbar do
  %ul.nav.navbar-nav
    %li.dropdown.notifications-menu
      %a.dropdown-toggle{href:"#", "data-toggle" => "dropdown"}
        %span{class: "flag-icon flag-icon-#{I18n.locale}"}
      %ul.dropdown-menu
        %li
          %ul.menu
            %li{class: "#{'active' if I18n.locale == :en}"}
              = link_to url_for(locale: :en) do
                %span.flag-icon.flag-icon-en
                English
            %li{class: "#{'active' if I18n.locale == :de}"}
              = link_to url_for(locale: :de) do
                %span.flag-icon.flag-icon-de
                Deutsch
    %li
      - if signed_in?
        = link_to sign_out_path, method: :delete do
          %i.fa.fa-power-off
          %span Sign out

Template regions

You can use content_for with the following regions:

• content_for(:admin_title)
• content_for(:admin_topbar)
• content_for(:admin_sidebar)

For adding extra stylesheets/javascripts use

• content_for(:stylesheets) - added to the head after theme stylesheets
• content_for(:javascripts) - added to the end of page's body after themes javascripts

Plugins

If you want to use plugins you have to manually load them.

Setup example for iCheck plugin:

# config/initializers/assets.rb
Rails.application.config.assets.precompile += %w(
  jquery-icheck.js jquery-icheck/skins/all.css
)

Add plugin to your Gemfile

  source 'https://rails-assets.org'
  gem 'rails-assets-jquery-icheck'

If you're using gems default layout you'll have to add assets by using content_for :stylesheets and content_for :javascripts.

# views/sessions/_form.html.haml
- content_for :stylesheets do
  = stylesheet_link_tag 'jquery-icheck/skins/all'

- content_for :javascripts do
  = javascript_include_tag 'jquery-icheck'
  :javascript
    $(function () {
      $('input').iCheck({
        checkboxClass: 'icheckbox_square-blue',
        radioClass: 'iradio_square-blue',
        increaseArea: '20%' // optional
      });
    });

Reordering items

Add Sortable gem to your Gemfile

source "https://rails-assets.org" do
  gem "rails-assets-Sortable"
end

Include javascripts in your admin.js

//= require Sortable/jquery.binding
//= require Sortable/Sortable
//= require admin_lte_rails/reorderable

In your route file

concern :reorderable do
  post "reorder", on: :collection
end

resources :posts, concerns: :reorderable

In your stylesheets require

//= require admin_lte_rails/reorderable

In your views make sure you have

tbody.orderable-list data-reorder-url=reorder_admin_categories_path
  - @categories.each do |category|
    tr data-record-id=category.id
      td.text-center.reorder-handle
        span.fa.fa-sort
      td
        = category.name

Toastr (growl-like notifications)

Include following in application.js:

  //= require toastr

Include following in application.css:

  *= require toastr
