Paperclip::Tempfile

Overriding some implementation of Tempfile

Public Instance Methods

make_tmpname(prefix_suffix, n) click to toggle source

Due to how ImageMagick handles its image format conversion and how Tempfile handles its naming scheme, it is necessary to override how Tempfile makes # its names so as to allow for file extensions. Idea taken from the comments on this blog post: marsorange.com/archives/of-mogrify-ruby-tempfile-dynamic-class-definitions

This is Ruby 1.9.3's implementation.

# File lib/paperclip/tempfile.rb, line 11
def make_tmpname(prefix_suffix, n)
  if RUBY_PLATFORM =~ /java/
    case prefix_suffix
    when String
      prefix, suffix = prefix_suffix, ''
    when Array
      prefix, suffix = *prefix_suffix
    else
      raise ArgumentError, "unexpected prefix_suffix: #{prefix_suffix.inspect}"
    end

    t = Time.now.strftime("%y%m%d")
    path = "#{prefix}#{t}-#{$$}-#{rand(0x100000000).to_s(36)}-#{n}#{suffix}"
  else
    super
  end
end
