# Ramaze::Helper::SendFile

The SendFile module can be used to stream a file to the user's computer. While the performance of the module isn't optimal it's convenient and relatively easy to use.

### Public Instance Methods

send_file(filename, content_type = nil, content_disposition = nil) click to toggle source

The send_file method streams the specified file to the user's browser.

@param [String] filename The name or path to the file which will be

    streamed to the user.

@param [String] content_type The type of file we're dealing with. For

    example, if we want to stream a JPG image we'd set this variable to
    'image/jpg'.

@param [String] content_disposition Value for the Content-Disposition

    header.

    # File lib/ramaze/helper/send_file.rb, line 20
    def send_file(filename, content_type = nil, content_disposition = nil)
      content_type ||= Rack::Mime.mime_type(::File.extname(filename))
      content_disposition ||= File.basename(filename)

      response.body = ::File.open(filename, 'rb')
      response['Content-Length'] = ::File.size(filename).to_s
      response['Content-Type'] = content_type
      response['Content-Disposition'] = content_disposition
      response.status = 200

      throw(:respond, response)
    end
