I have a form with multiple file upload fields (1-10), of which 2-10
are optional. So i need to cycle thru all file fields and pick only
those that have a file attached. Selecting only one file in the form,
the paramters look simple: “image”=>{“file_1”=>#<File:/tmp/CGI344.4>,
“file_2”=>"", “file_3”=>""}, so I tried this:
params[:image].each_value do |incomming_file|
unless incoming_file.empty?
#do file processing
end
end
However, this is still causing the empty fields (file_2, file_3 etc)
to be processed, which raises all sorts of errors as the File.methods
are not available of course. I tried .nil? and various other tests
but i simply can’t get it to skip those empty file fields. any ideas?
Thank you.
