Combine PDF in Rails with combine_pdf

I'm trying to use the gem combine_pdf in order to combine a number of PDFs in my app. They are located in assets/forms/packages/1.pdf 2.pdf 3.pdf.

I'm trying to following the gem's guide but the code yields an error:

@pdfForms = CombinePDF.new
@pdfForms << CombinePDF.new('assets/forms/packages/1.pdf')

I get a runtime error:

root is unknown - cannot determine if file is Encrypted

Any help is much appreciated, or another way to merge pdfs. The gem pdf-merge fails with my app due to its dependency on rjb.

Thanks!

Try using CombinePDF.load instead of CombinePDF.new.

new will try both loading the file and parsing the string - so you won't see the file loading exceptions.

It could be that the file path is wrong and CombinePDF is trying to parse 'assets/forms/packages/1.pdf' as if it were the content of a PDF file.

Your code should look like this:

@pdfForms = CombinePDF.new
@pdfForms << CombinePDF.load('assets/forms/packages/1.pdf')

Try to open a file by using

File.open("assets/forms/packages/1.pdf")

If this is not working then your file path is wrong. If this pdf file is in your app/assets folder of your application then you can access it by using:

file_path = Rails.root.join("app", "assets", "forms", "packages","1.pdf")

File.open(file_path)
