Change tmp folder for uploaded files

Question

All my downloaded files are temporarily stored in the /tmp folder.

I would like to change this folder because the /tmp folder is too small. This does not help me download the file and after downloading move it somewhere else.

I already tried changing ENV['TMPDIR'] , ENV['TMP'] and ENV['TEMP'] to something else, but my downloaded files (RackMultipart *) are still temporarily stored in /tmp .

How can I change this behavior? Of course, I could install /tmp to another location, but it would be easier to tell Rails / Rack / Thin / Apache / ... where to store the files. I do not use paperclip etc.

For my server, I use Apache as a proxy balancer to transfer traffic to 4 thin servers.

I have a Rails Rails 4 project using ruby ​​2.0.

Edit:

 def create file = params[:sample_file][:files].first md5_filename = Digest::MD5.hexdigest(file.original_filename) samples = Sample.where("name in (?)", params["samples_#{md5_filename}"].map {|exp| exp.split(" (").first}) rescue [] file_kind = FileKind.find(params[:file_kind]) @sample_file = SampleFile.new @sample_file.file_kind = file_kind @sample_file.samples = samples @sample_file.original_file_name = file.original_filename @sample_file.uploaded_file = file #TODO: .. @sample_file.user = current_user ... #many other stuff ... respond_to do |format| if @sample_file.save format.html { render :json => [@sample_file.to_jq_upload].to_json, :content_type => 'text/html', :layout => false } format.json { render json: {files: [@sample_file.to_jq_upload]}, status: :created, location: @sample_file } else format.html { render action: 'new' } format.json { render json: {files: [@sample_file.to_jq_upload]}.to_json, status: :ok} end end end

If the settings for TMPDIR, TMP, TEMP do not work, it is possible that the directory you specified does not exist or is not writable. Or the variable $ SAFE> 0. The tmp folder is defined using the Dir.tmpdir function (see http://www.ruby-doc.org/stdlib-1.9.3/libdoc/tmpdir/rdoc/Dir.html#method-c -tmpdir ).

 class Dir def Dir::tmpdir tmp = '.' if $SAFE > 0 tmp = @@systmpdir else for dir in [ENV['TMPDIR'], ENV['TMP'], ENV['TEMP'], @@systmpdir, '/tmp'] if dir and stat = File.stat(dir) and stat.directory? and stat.writable? tmp = dir break end rescue nil end File.expand_path(tmp) end end end

Ruby 2.1

 def Dir::tmpdir if $SAFE > 0 tmp = @@systmpdir else tmp = nil for dir in [ENV['TMPDIR'], ENV['TMP'], ENV['TEMP'], @@systmpdir, '/tmp', '.'] next if !dir dir = File.expand_path(dir) if stat = File.stat(dir) and stat.directory? and stat.writable? and (!stat.world_writable? or stat.sticky?) tmp = dir break end rescue nil end raise ArgumentError, "could not find a temporary directory" if !tmp tmp end end 

So, if you set the TMP env variables, make sure the lines below are true

• $ SAFE == 0
• File.stat ("you_dir")
• File.stat ("you_dir"). Catalog?
• File.stat ("you_dir"). Recording?

Another way to set tempdir is to override tmpdir in your rails initializer, but obviously this bypasses any directory check, so you have to make sure that it exists / is written

 class Dir def self.tmpdir "/your_directory/" end end
