INSTALL

1. Download from GitHub and unzip into vendor/plugins. (Rails 5 : Add Gem "record_select" in gem file)
2. Enable and configure it on a controller.

3. class UsersController < ApplicationController

   record_select :per_page => 5, :search_on => 'username'

end 1. Optional: to use RecordSelect RESTfully, add the following to your routes.rb: map.resources :model_id, :collection => {:browse => :get}, :member => {:select => :post} 1. Now go ahead and use it somewhere.

HOWTO

Let's assume that you have two models, NewsArticles and Authors, and every NewsArticle belongs_to :author. 

Let's assume that your goal is to set up the scaffold for NewsArticles so that the create/update forms use RecordSelect to pick the appropriate Author. To accomplish this using the default intelligence of these two plugins, you need to do two things:

1. Configure RecordSelect on the AuthorsController.
2. Configure the NewsArticles scaffold with config.columns[:author].form_ui = :record_select.
3. If you want to use both RESTfully, combine the configuration in your routes.rb: map.resources :news, :active_scaffold => true, :collection => {:browse => :get}, :member => {:select => :post}

It's important to understand that the relationship between the two models is mirrored between the two controllers. The NewsArticlesController will display a form that calls RecordSelect via /authors/browse. If you want to customize which authors are returned in the result set (e.g. change the number of authors per-page), you need to configure RecordSelect on the AuthorsController.

Advice from Sergio Cambra

1. You are reading a really old web, recordselect is not in google code anymore, 
but README in github is not updated either 

Do not change your layout, don't add record_select_includes, it doesn't exist 
anymore because current way is adding //= require record_select to asset 
manifest. 

Anyway, you don't have to add anything else to your application 
manifest, ActiveScaffold already includes record_select to assets through 
record_select bridge when recordselect gem is installed. 
Q2. ActionView::Template::Error (No route matches {:*action=>"browse"*,

A2
Add record_select_routes to your resources routes:

resources :rootcauses do

record_select_routes

concerns :active_scaffold

end

It will define get browse route on collection

Q3. But its shows as Root Cause:FEATURE, how can I make as FEATURE ?

A3
It uses to_label method in your model, as ActiveScaffold, you can change to_label method in your model. Or setup recordselect to use different method or partial:

Here is some old doc, still applies:

https://code.google.com/archive/p/recordselect/wikis/HTMLRecords.wiki

In summary, you can use partials, and set partial name with :label option:

record_select ..., :label => 'partial name'

Or use a proc or lambda:
