How to set up and validate locally

In console:

project = Project.find(1)
user = User.find(1) # user with sufficient access to project
Feature.enable(:import_work_items_csv)
csv_io = FileUploader.new(project)
csv_io.store!(File.open("/path/to/work_items.csv"))
service = ::WorkItems::ImportCsvService.new(user, project, csv_io)
service.execute

You can also just check the mail bit by feeding it a project and some fake results:

Notify.import_work_items_csv_email(user.id, project.id, {:success=>2, :error_lines=>[3,4], :parse_error=>false}).deliver!

Check the letter_opener for incoming mail. 👉 http://gdk.test:3443/rails/letter_opener.

You can also view sample mailer with fake info in http://localhost:3000/rails/mailers/notify/import_work_items_csv_email. If you play with the values on your local in app/mailers/previews/notify_preview.rb you can preview different what different values will look like.
