Ruby on Rails - Roo gem | Issue opening active record attachment

Question

Status:

• I have a simple new Ruby On Rails App
• I need to import some data from MS Excel in.xlsx format
• I programmed an uploading to ActiveRecord as attachment via an attribute called 'excel'
• I found a gem called Roo which should do the opening of the attachment
• ...via: Roo::Excelx.open() command
• Then executes the accessing part of the file

Issue: Roo::Excel.open() doesnt work for:

1. Roo::Excel.open(excel)
2. Roo::Excel.open(excel.attachment)

What is the correct command to execute to open the ActiveRecord::Attachment ?

Answer 1

how about do this?

ModelName.excel.open do |file|
 xlsx = Roo::Spreadsheet.open(file)
end

Answer 2

Actually I got an answer outside of Stackoverflow which was this:

Roo::Spreadsheet.open(ActiveStorage::Blob.service.path_for(excel.key), extension: 'xlsx')

I loaded one row from the Excel so must change code but opening it seemed to have worked: :-)
