Forum: Ruby on Rails encrypt the pdf

I am encrypting the pdf in rails using pdf-toolkit

here is my code:
PDF::Toolkit.pdftk(infile output outfile user_pw rails)

It is giving error saying that
undefined method user_pw

Any suggestions

Have you provided that method or variable?  If not then what do you
think that user_pw is referring to?

I think that is predefined in pdftk

Can you point me to the docs that make you think that in

that user_pw is predefined in pdftk?

As you have coded it ruby will look for a variable or method called
user_pw from which to get the value to pass to pdftk.  If you want to
pass the string user_pw then I guess that you must put "user_pw".

That is the usage summary for the command line tools, not for the ruby
api. For starters you'll need to separate your arguments with commas,
not spaces

It is working pdf is encrypted

my_pdf = 
PDF::Toolkit.open(directory+@encrypt_pdf.attach.url.split('?')[0].to_s)
        my_pdf.user_password=@encrypt_pdf.user_password
        my_pdf.owner_password=@encrypt_pdf.owner_password
