Add a feature that will let admins upload products to the Spree database from a .csv file
A form for file uploading is available at /admin/import_files/new
Index of last 10 uploads is at /admin/import_files
- Add validation for file extension and size
- Move file storing from DB to cloud(ex. AWS S3)
Run 'rspec'
At its current state the csv example file doesn't have all data to save Products. So tests fail. Admin side authorisation is not stubbed. So not tests for admin side.
