Colorcake

Find colors and generate palette. So you can show palette and search models by color

Installation

Add this line to your application's Gemfile:

gem 'colorcake'

And then execute:

$ bundle

Or install it yourself as:

$ gem install colorcake

Usage

  1. Run rails generate colorcake:install to install initializer.

  2. Add to your model include and method image_path_for_color_generator model should have character field palette

    class Photo include Colorable

     def image_path_for_color_generator
   image.big.path
 end

    end

Testing

Put images like 0.jpg .. 16.jpg in fixtures and run rake test then you should see html files with generated colors and photos

То, что автор гема называл тестами, переведено в несколько иную форму -- читать test/functionals/README.md

Так выглядит граф вызовов ф-ций колоркейка с примерными пояснениями:

after_create :process_colors : /colorcake/app/models/concerns/colorable.rb
  |
  |  [ a lot of times in marvin ]
  |       |
  v       v
process_colors      : /colorcake/app/models/concerns/colorable.rb
  |                 alias to generate_colors
  |
  |  preview_teaser : /marvin/app/controllers/reports_controller.rb
  |       |         : /marvin/app/controllers/marvin/posts_controller.rb
  v       v
generate_colors     : /colorcake/app/models/concerns/colorable.rb
  |       |         extract_colors[0].each{ colors.create }
  |       |         generate_palette extract_colors[1]
  |       v
  |  extract_colors : /colorcake/lib/colorcake.rb
  |                 return [colors, colors_hex]
  |
generate_palette    : /marvin/app/models/photo.rb
  |                  (/colorcake/app/models/concerns/colorable.rb)
  |                 assign_attributes palette: create_palette(colors), modified_palette: nil
  v
create_palette      : /colorcake/lib/colorcake.rb
                    colors = (slim|expand)_palette colors

Таким образом, image_generation_test.rb, дергая generate_colors и create_palette по сути имитирует generate_colors, сохраняя палитру (palette) и поисковые цвета (colors) не в базу, а в html.
