shikigami / 式神

shikigami is meant to make creating basic CRUD Rails apps as brain dead easy as possible.

Add this line to your application's Gemfile:

gem "shikigami"

And then execute:

$ bundle install

shikigami utilizes the I18n library and you will need to have these information in your locale file:

zh-TW:
  success:
    create: 新建資料成功
    update: 修改資料成功
    destroy: 刪除資料成功

  actions:
    new: 新增
    edit: 修改
    show: 檢視
    destroy: 刪除

  confirm:
    destroy: 確認要刪除？

  warnings:
    no_data: 尚無資料

Or, just let shikigami generate the locale file for you:

$ rails generate shikigami:install

shikigami also assumes that you use Kaminari for pagination and bootstrap for layout.

Tested with Rails 5 and Ruby 2.3.

Original credit goes to @ryudoawaru. I've been using this almost everywhere, with some tweaks of my own, so I figured I'd might as well put together a gem.

shikigami provides an abstract controller to handle CRUD actions in Shikigami::BaseController. Simply inherit your controllers from shikigami, specify the relevant current_scope and resource_params, and you're done. shikigami will do the remaining boring stuff for you.

# all set!
class BooksController < Shikigami::BaseController
  def current_scope
    Book
  end
  
  def resource_params
    parms.require(:book).permit(:title, :author)
  end
end

Then, in your view, just use current_collection or current_object to access your data.

# app/views/books/show.html.slim
h1 = current_object.title

# app/views/books/index.html.slim
- current_collection.each do |item|
  = item.title

Obviously, shikigami is only meant for the most basic CRUD Rails apps. If you need something more fancy, you shouldn't be using it :p

Generates the following HTML:

# no_data_alert
<div class="alert alert-warning">尚無資料</div>

Generates the following HTML. bs_dd_toggle for short. Yeah, I'm lazy.

# bootstrap_dropdown_toggle("something")
<a class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">something<span class="caret"></span></a>

Generates a bootstrap button style link. bs_btn for short.

# bs_btn(:edit, "#")
<a class="btn btn-xs btn-warning" href="#">修改</a>

By default, shikigami generated buttons will be sized as .btn-xs. Unless specified otherwise, it will use .btn-info for show actions, .btn-warning for edit actions, and .btn-danger for destroy actions.

You can also pass in methods and confirmation:

# bs_btn(:destroy, "#", method: :delete, confirm: true)
<a class="btn btn-xs btn-danger" data-confirm="確認要刪除？" rel="nofollow" data-method="delete" href="#">刪除</a>
