Rails::Views

View Components for Ruby and Rails.

The gem provides view models for Ruby web applications. View models are plain objects that represent a part of the web page. View models can also render views, and be nested.

This gem bases on cells.

Installation

Add this line to your application's Gemfile:

gem 'rails-views'

And then execute:

$ bundle

Usage

This gem bases on cells, but includes only Concept logic.

A view is a light-weight class with show.slim temlate with base view logic.

class Comment::Cell < Rails::View

  private

  property :body, :author

  def author_link
    link_to "#{author.email}", author
  end
end

Rendering

Gem provides logic for rendering cells instead of ActionView templates.

def CommentsController < ApplicationController
  def index
    render cell: true # will render Comments::Cell
  end

  def show
    @comment = Comment.find(params[:id])

    render cell: :show, model: @comment # will render Comments::Show::Cell with @comment as model
  end

  def new
    @comment = Comment.new
    @user = User.find(params[:user_id])

    render cell: 'user/comment', model: @comment, options: {user: @user} # will render User::Comment::Cell with @comment as model and user options
  end
end

Helpers

Also gem provides new helpers for rails.

Flash

Provide method for working with flash.

= flash[:notice]

Render partials array

Method render_each_and_join can render array of templates and join it in one string.

class User::Info::Cell < Rails::View
  private

  def parts_of_info
    %w(contact_information about jobs transactions_list)
  end

  def info_body
    render_each_and_join(parts_of_info)
  end
end

class User::ShortInfo::Cell < User::Info::Cell
  private

  def parts_of_info
    %w(contact_information about)
  end
end

Options

Provide options reader. You can have automatic readers to the options's fields by using ::option

class User::Comment::Cell < Rails::View
  private
    options :user # delegate to options[:user]

    delegate :email, to: :user, prefix: true
end
