Rails save tempfile to S3

Question

I'm trying to save a pdf to S3 by using a tempfile. I'm sure the pdf is being created correctly because I use the same code to email pdfs.

A file is being saved to S3, but it's empty.

pdf is created by CombinePDF.new - so, pdf contains the pdf data.

This is my code:

@file = Tempfile.new('costprojectspdf')
@file.write(pdf)
@obj = @bucket.objects.create("costprojects.pdf", @file.read)

Is @file.read correct? Do I need to @file.close?

Thanks for your help!

Answer 1

如果pdf是原始数据，则可以：

@obj = @bucket.objects.create("costprojects.pdf", pdf.to_pdf)
