Question

I have a TempFile object that is a zip file, and I wish to read from it as follows:

Zip::ZipFile.open_buffer(tempfile) do |zipfile|
    ...
end

However, when I do this, I get the following error:

Zip::ZipFile.open_buffer expects an argument of class String or IO. Found: Tempfile

I’ve also tried

Zip::ZipFile.open(tempfile.path) do |zipfile|
    ...
end

But that returns

can't dup NilClass

How can I process a temporary zip file?

Answer 1

It turns out that the temporary file was corrupted, so the

can't dup NilClass

error was as a result of trying to read the corrupted file.

Therefore the solution is to use

Zip::ZipFile.open(tempfile.path) do |zipfile|
    ...
end
