Spree Reporting Tutorial

This is a gem that serves as a tutorial to add new reports to Spree Admin. It adds a simple report "Unavailable Products" to the existing "Sales Total" report that comes from a basic Spree installation.

Running Tests

1. Generate the dummy test app.

bundle exec rake test_app

2. Run the tests.

bundle exec rake spec

Build and Install The Gem

bundle exec rake install

Adding A Report

There are several things that need to be done in order to create a new report in Spree.

1. Register your report in the Spree::Admin::ReportsController decorator so shows up in /admin/reports. Currently this is done in a before_filter to work around issues with Spree.t text localization.

Spree::Admin::ReportsController.class_eval do
  before_filter :advanced_reporting_setup, only: [:index]

  ...

  def advanced_reporting_setup
    Spree::Admin::ReportsController.add_available_report! :unavailable_products
  end
end

2. Create the controller action that will handle the report.

Spree::Admin::ReportsController.class_eval do

  ...

  def my_report
    @products = Spree::Product.all
  end

  ...

end

3. Add the routes to config/routes.rb. These routes will be added in addition to the existing Spree routes and they should not interfere with each other. You must create a GET and POST route for the rendering and form-submission interactions

Spree::Core::Engine.routes.prepend do
  namespace :admin do
    resources :reports, :only => [] do
      collection do

        ...

        get   :my_report
        post  :my_report

        ...

      end
    end
  end
end

4. Build the report template. This is your standard ERB happiness!

5. Write tests. There are sample tests derived from the "Sales Total" tests in Spree Core.
