M3TableAdmin

Add to your gem file:

gem 'm3_table_admin', :git => "git://github.com/mice3/M3TableAdmin.git"

Create routes for viewing and editing your tables (this will add view/edit option for users table):

namespace :m3_table_admin, path: "admin" do
  get "/", to: "users#index"
  resources :users
end

Create controller with table definition in: "controllers/m3_table_admin/users_controller.rb"

class M3TableAdmin::UsersController < M3TableAdmin::ApplicationController

  before_action :set_table

  private
    def set_table
      @table = M3TableAdmin::Table.new("users")
      @table.add_column("email", "text", {"index" => true})
      @table.add_column("role", "text", {"index" => false})
    end
end

If a model is used in the autocomplete input, you must add inside your model

def m3_table_admin_autocomplete_label email #this is the name of the field, that you want to display end

And there must be defined also a scope.

scope :m3_table_admin_autocomplete_scope, ->(q, user = nil) { where("email LIKE ?", "%#{q}%").select("email as value, id as id") }

Manually create navigation header file (and modify it to your needs) in: "views/layouts/m3_table_admin/_navigation.html.haml"

%nav.navbar.navbar-default.navbar-fixed-top
  .col-sm-12
    .navbar-header
      .navbar-brand
        = link_to "/" do
          = "Logo goes here"
          / = image_tag "logo.png"
    .collapse.navbar-collapse
      %ul.nav.navbar-nav.navbar-right
        %li
          = link_to "Users", m3_table_admin_users_path
        %li
          = link_to "Logout?", "#"

For authorization purposes is added a concern and a method require_authorization. Those two things must be defined. the AuthorizationControllerConcern must de created inside controllers/concerns .Inside this file a function named require_authorization must also be defined. Example module AuthorizationControllerConcern extend ActiveSupport::Concern

module ClassMethods
  # Runs authorization check for current user and restricts access
  # for unauthorized roles.
  def require_authorization(options={})
    self.class_eval("
      before_filter :handle_authorization, #{options}
      def handle_authorization
        not_authorized unless authorized?
      end
    ")
  end
end

# Checks if current user is authorized for controller/action.
def authorized?
  true
end

# Called when access is restricted.
def not_authorized
  redirect_to root_path
end

end

Data types that can be used: add_column ( name, type = "text", attributes = {}) add_autocomplete_column ( name, select = "name", attributes = {}) add_timestamp_column ( name, format, attributes = {}) add_wysihtml5_column ( name, attributes = {}) #rich text editor add_checkbox_column ( name, collection, attributes = {}) add_country_column ( name, attributes = {}) add_dropdown_column ( name, collection, attributes = {}) add_json_column ( name, attributes = {})

You can also add filters add_filter ( name, find_in = "")

On top you can add additional buttons add_additional_button ( name, url, method )

Other things that can be customized are (After you define a new table @table = M3TableAdmin::Table.new("users")): Disable/enable the destroy ability at the end of the index table @table.enable_destroy = true #default true Disable/enable adding of new values @table.enable_add_new = true #default true Disable/enable the edit ability at the end of the index table @table.enable_edit = true #default true Disable/enable showing of ids at the beginning of the index table @table.show_ids = false #default false Disable/enable pagination of the index table @table.enable_pagination = true #default true Disable/enable sorting of the index table @table.enable_sorting = false #default true Add filter just those locales (the value) in connection with @row_has_locale @table.filter_locale = false #default true Sorting of index table ASC or DESC @table.sort_type = "DESC" #default DESC
