Developing on a Mac

(For Rails 3.0 and 2.3 see older versions)

Use the gem

gem install active_scaffold

Add it to your Gemfile of course:

gem 'active_scaffold'

Then you need to add active_scaffold to your assets pipeline, by adding it as a comment at the bottom of the following two ‘manifests’ files:

in Rails.root/app/assets/stylesheets/application.css (or application.scss)

*= require active_scaffold

in Rails.root/app/assets/javascripts/application.js

//= require active_scaffold

Finally, install the routes:

rails g active_scaffold:install

Use active_scaffold or active_scaffold_controller generators instead of resource or controller generators in rails 3. They will create controllers with active_scaffold enabled, as well as active_scaffold routes:

rails g active_scaffold Model attr1:type attr2:type
rake db:migrate

Note: On rails 4+ you should use

rails g active_scaffold:resource Model attr1:type attr2:type
rake db:migrate

That’s it! Your first ActiveScaffold is up and running.

Your scaffold should be up and running with default everything right now. Not quite how you want it?

First let’s introduce the global config block. You probably noticed that the active_scaffolding includes everything in the table. Let’s remove a few of these columns with one easy config block. Create an active_scaffold.rb initializer in config/initializers. And don’t forget to restart your application whenever you make changes to this file.

# config/initializers/active_scaffold.rb
ActiveScaffold.defaults do |config| 
  config.ignore_columns.add [:created_at, :updated_at, :lock_version]
end

It’s recommended to call `clear_helpers` in ApplicationController, as some helpers defined by ActiveScaffold, such as active_scaffold_enum_options, options_for_association_conditions, association_klass_scoped, are usually overrided for different controllers, and it may cause issues when all helper modules are available to every controller, specially when models have associations or columns with the same name but need different code for those overrided helper methods.

class ApplicationController < ActionController::Base
  clear_helpers

Let’s have a look at the local config block. This block goes in the model’s corresponding controller. The config block for the Company model goes in the CompaniesController. ActiveScaffold restricts one model per controller. Now for an example:

class CompaniesController < ApplicationController

  active_scaffold :company do |config|
    config.label = "Customers"
    config.columns = [:name, :phone, :company_type, :comments]
    list.columns.exclude :comments
    list.sorting = {:name => 'ASC'}
    columns[:phone].label = "Phone #"
    columns[:phone].description = "(Format: ###-###-####)"
  end

end

ActiveScaffold tries to be flexible: change the labels, decide which columns to include, control the columns included per-action, define a default sort order, specify a column label and a column description. Check the API docs to see what’s possible!
