NutritionLabelPlugin¶ ↑

Nutrition label generation for Rails 3.1 using the asset pipeline.

1. If using bundler, add to your Gemfile and run bundle install:

   gem nutrition_label_plugin
   

2. Otherwise run ‘gem install nutrition_label_plugin’

3. To add the CSS file to your load path, add to your app’s application.css file:

   *= require nutrition_label_plugin

Currently, there is a single method available that accepts a hash of all optional parameters.

create_base_label(args)

The method returns html output, which you can use in your views to show these awesome nutrition fact labels.

create_base_label takes a number of optional arguments in the form of a hash:

• :name => “string”

• :yield => float, in grams

• :servings => float, # of servings

• :calories => float, # of calories

• :fat => float, in grams

• :saturated_fat => float, in grams

• :trans_fat => float, in grams

• :cholesterol => float, in milligrams

• :sodium => float, in milligrams

• :carbohydrate => float, in grams

• :fiber => float, in grams

• :sugar => float, in grams

• :vitamin_C => float, in milligrams

• :vitamin_A => float, in IU (international units)

• :Iron => float, in milligrams

• :calcium => float, in milligrams

• Automatic rounding according to USDA conventions

• Additional optional nutrients

• Additional output formats

• If you have ideas for features, let me know and I’ll see what I can do!

If you have any feedback or want to add methods other than the basic nutrition label, feel free to fork and send a pull request.
