Warped

Develop rails applications at the speed of thought. Warped is a collection of tools and utilities that make it easier to develop rails applications.

Installation

Install the gem and add to the Rails application's Gemfile by executing:

$ bundle add warped

Then run the generator to create the configuration file:

$ rails generate warped:install

The generator will create a file at config/initializers/warped.rb with the default configuration.

Installation for rails fullstack apps

For using the views provided by the gem, your app will need to have the following:

  1. rails/importmap-rails configured
  2. hotwired/stimulus-rails configured

Add the following to your config/importmap.rb:

pin_all_from "app/javascript/controllers/warped", under: "controllers/warped"

This will import all the stimulus controllers provided by the gem.

Add the following to your app/javascript/controllers/index.js, bellow the eagerLoadControllersFrom("controllers", application) line:

eagerLoadControllersFrom("warped/controllers", application)

Include the css provided by the gem in your app/views/layouts/application.html.erb:

<%= stylesheet_link_tag "warped/base" %>
<%= stylesheet_link_tag "warped/table" %>
<%= stylesheet_link_tag "warped/search" %>
<%= stylesheet_link_tag "warped/filters" %>
<%= stylesheet_link_tag "warped/pagination" %>

Usage

Warped provides utilities for making it easier to develop rails applications. The utilities are organized into modules and can be used by including the module in the class that needs the utility. The utilities are organized in concepts used by most rails applications:

  • Controllers
  • Services
  • Jobs

Controllers

The Warped::Controllers module defines five concerns that can be included in a controller to provide additional functionality:

  • Warped::Controllers::Filterable
  • Warped::Controllers::Searchable
  • Warped::Controllers::Sortable
  • Warped::Controllers::Paginatable
  • Warped::Controllers::Tabulatable

Warped::Controllers::Filterable

The Filterable concern provides a method to filter the records in a controller's action. The method filterable_by is used to define the filterable fields and the filter method to use.

class UsersController < ApplicationController
  include Warped::Controllers::Filterable

  filterable_by :name, :email, :created_at

  def index
    users = filter(User.all)
    render json: users
  end
end

The filter method will use the query parameters to filter the records. For example, to filter the users by name, email, and created_at, the following query parameters can be used:

GET /users?name=John
GET /users?email=john@example.com
GET /users?created_at=2021-01-01

Tip

It's highly recommended to use the type-safe filter methods provided by the gem. This prevents invalid queries from being executed on the database. See the Filterable documentation for more information.

Complete documentation for Warped::Controllers::Filterable.

Warped::Controllers::Searchable

The Searchable concern provides a method to search the records in a controller's action.

By default it calls the scope search on the model, and uses the query parameter q to search the records.

# app/models/user.rb
class User < ApplicationRecord
  # You can define your own search scope and use standard sql
  # scope :search, ->(query) { where('name LIKE ?', "%#{query}%") }

  # Or use pg_search
  include PgSearch::Model
  pg_search_scope :search, against: [:name, :email]
end

# app/controllers/users_controller.rb
class UsersController < ApplicationController
  include Warped::Controllers::Searchable

  def index
    users = search(User.all)
    render json: users
  end
end

Request examples:

GET /users?q=John
# calls #search(User.all, search_term: 'John', model_search_scope: :search) in the controller

Complete documentation for Warped::Controllers::Searchable.

Warped::Controllers::Sortable

The Sortable concern provides a method to sort the records in a controller's action.

The method sortable_by is used to define the sortable fields.

class UsersController < ApplicationController
  include Warped::Controllers::Sortable

  sortable_by :name, :created_at

  def index
    users = sort(User.all)
    render json: users
  end
end

Tip

It's highly recommended to use the type-safe sort methods provided by the gem. This prevents invalid queries from being executed on the database. See the Sortable documentation for more information.

This will use the query parameter sort_key and sort_direction to sort the records.

  • The default sort direction is desc.
  • The default sort key is :id.

Example requests:

GET /users?sort_key=name # sort by name in descending order
GET /users?sort_key=created_at&sort_direction=asc # sort by created_at in ascending order

When calling sort in a controller action, and the sort parameters are not provided, the default sort key and direction will be used.

class UsersController < ApplicationController
  include Warped::Controllers::Sortable

  sortable_by :name, :created_at

  def index
    users = sort(User.all)
    render json: users
  end
end

Request examples:

GET /users # sort by id in descending order

Complete documentation for Warped::Controllers::Sortable.

Warped::Controllers::Pageable

The Pageable concern provides a method to paginate the records in a controller's action.

The method paginate is used to paginate the records. It will use the query parameters page and per_page to paginate the records.

class UsersController < ApplicationController
  include Warped::Controllers::Pageable

  def index
    users = paginate(User.all)
    render json: users, meta: pagination
  end
end

Request examples:

GET /users?page=1&per_page=10 # returns the first page of users with 10 records per page
GET /users?per_page=25 # returns the first page of users with 25 records per page
GET /users?page=2&per_page=25 # returns the second page of users with 25 records per page

Complete documentation for Warped::Controllers::Pageable.

Warped::Controllers::Tabulatable

The Tabulatable concern provides a method to filter, sort, search, and paginate the records in a controller's action.

The method tabulate is used to filter, sort, search, and paginate the records. So, in the case that the controller action needs to filter, sort, search, and paginate the records, the tabulate method can be used.

The tabulatable concern provides the tabulatable_by method, which passes the values to filterable_by and sortable_by.

class UsersController < ApplicationController
  include Warped::Controllers::Tabulatable

  tabulatable_by :name, :email, :created_at

  def index
    users = tabulate(User.all)
    render json: users, meta: pagination
  end
end

Request examples:

GET /users?age[]=18&age[]=30&age.rel=between&sort_key=name&sort_direction=asc&q=John&page=2&per_page=10
# returns the second page of users with 10 records per page, where the age is between 18 and 30, sorted by name in ascending order, and searched by the term John

Just like paginate, when calling the tabulate method in the controller action, the pagination method can be used to access the pagination information.

Complete documentation for Warped::Controllers::Tabulatable.

Views

Warped comes with a set of partials and stimulus controllers that can be used to make development of index views easier/faster.

In order to use the views provided by the gem, warped provides ::Ui modules for each of the before menttioned concerns. These Warped::Controllers::<ConcernName>::Ui provide the helper methods needed by the partials in order to work.

The partials are:

  • Warped::Controllers::Filterable::Ui -> warped/_filters.html.erb
  • Warped::Controllers::Searchable::Ui -> warped/_search.html.erb
  • Warped::Controllers::Pageable::Ui -> warped/_pagination.html.erb
  • Warped::Controllers::Tabulatable::Ui -> warped/_table.html.erb

Example:

# app/models/user.rb
class User < ApplicationRecord
  # first_name :string
  # last_name :string
  # email :string
  # created_at :datetime

  scope :search, ->(query) { where('first_name LIKE ? OR last_name LIKE ? OR email LIKE ?', "%#{query}%", "%#{query}%", "%#{query}%") }

end

# app/controllers/users_controller.rb
class UsersController < ApplicationControlelr
  include Warped::Controllers::Tabulatable::Ui

  tabulatable_by name: { kind: :string }, email: { kind: :string }, created_at: { kind: :date_time }

  def index
    @users = tabulate(User.all)
  end

  def show
    @user = User.find(params[:id])
  end

  def destroy
    User.find(params[:id]).destroy
    redirect_to users_path
  end
end
# app/views/users/index.html.erb
<%= render "warped/table", collection: @users,
                           path: users_path,
                           columns: [
                             Warped::Table::Column.new(:id, 'ID'),
                             Warped::Table::Column.new(:full_name, 'Full Name', method: ->(user) { [user.first_name, user.last_name].compact_blank.join(" ") }),
                             Warped::Table::Column.new(:email),
                             Warped::Table::Column.new(:created_at, 'Created At', method: ->(user) { user.created_at.strftime('%Y-%m-%d') })
                           ],
                           actions: [
                             Warped::Table::Action.new('Show', ->(user) { user_path(user) }),
                             Warped::Table::Action.new('Delete', ->(user) { user_path(user) }, turbo_method: :delete, turbo_confirm: 'Are you sure?')
                           ],
                           turbo_action: :replace
                          %>

The code above, renders a table with:

  • The columns ID, Full Name, Email, and Created At, all of which are sortable.
  • The actions Show and Delete for each user. The action Delete will use the DELETE method and will ask for confirmation before executing the action.
  • The filters for the name, email, and created_at fields.
  • A search input that will search the users by the term provided.
  • A pagination component that will paginate the users, showing 10 users per page by default.
  • The table filtering/sorting/searching/pagination will be done using the turbo-action=replace.

Services

The gem provides a Warped::Service::Base class that can be used to create services in a rails application.

class PrintService < Warped::Service::Base
  def call
    puts 'Hello, world!'
  end
end

The call method is the entry point for the service. It can be overridden to provide the service's functionality.

class PrintService < Warped::Service::Base
  def call
    puts "Hello, #{name}!"
  end

  private

  def name
    'world'
  end
end

The way of calling the service is by calling the call method on the service class. The .call method is a class method that creates a new instance of the service, passing the arguments to the initialize method, and then calls the call method on the new instance.

PrintService.call # Executes new.call

If you want to pass arguments to the service, you can so by defining the initialize method in the service class.

class PrintService < Warped::Service::Base
  def initialize(name = 'John')
    @name = name
  end

  def call
    puts "Hello, #{@name}!"
  end
end
PrintService.call # Executes new.call, prints "Hello, John!"
PrintService.call('world') # Executes new('world').call, prints "Hello, world!"

Complete documentation for Warped::Services.

Jobs

The gem provides a Warped::Jobs::Base class that can be used to create background jobs in a rails application.

class PrintJob < Warped::Jobs::Base
  def perform
    puts 'Hello, world!'
  end
end

Warped::Jobs::Base is a subclass of ActiveJob::Base, and can be used as a regular ActiveJob job.

The superclass can be overriden to inherit from a different job class, by changing it in the config/initializers/warped.rb file.

# config/initializers/warped.rb
Warped.configure do |config|
  config.job_superclass = 'ApplicationJob'
end

Complete documentation for Warped::Jobs.
