UnobtrusiveResources

This gem provides convenient set of methods for resource management to keep your controllers as "skinny" as possible. Main idea is to organize controller actions' code in terms of resource CRUD.

Example:

class BotsController < ApplicationController
  # ...

  unobtrusive finder_method: :find_by_slug!,
              find_for_create_by: :slug,
              resource_class: Bot,
              relationship_name: :bots,
              permitted_params_key: :bot,
              permitted_params_create_value: %i[name code],
              permitted_params_update_value: %i[name code]
  def index
    respond_with(collection)
  end

  def show
    respond_with(resource)
  end

  def new
    build_resource
    respond_with(resource)
  end

  def create
    find_or_create_resource
    respond_with(resource)
  end

  def update
    update_resource
    respond_with(resource)
  end

  def destroy
    destroy_resource
    respond_with(resource)
  end
  # ...
end

Keep in mind, that following methods should be defined (or configured with unobtrusive method call) in order to make default configuration to work properly:

• relationship_name
• resource_class
• find_for_create_by
• permitted_params_key
• permitted_params_create_value
• permitted_params_update_value
• parent_class
• parent_permitted_params_key

For real-life projects most resource related actions will be a bit more complicated. In such cases we can easily change underlying logic for, say, resource creation (redefine method):

class BotsController < ApplicationController
  # ...

  private

  # Here `Bot` may be some model class or service object.
  def create_resource
    @_resource = Bot.custom_create(permitted_params)
  end
  # ...
end

Installation

Add this line to your application's Gemfile:

gem 'unobtrusive_resources'

And then execute:

$ bundle

Or install it yourself as:

$ gem install unobtrusive_resources

Usage

There is no need for additional initializer. All necessary methods will be included into ActionController::Base via ActiveSupport.on_load (lazy load hook).

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
