Hi,
I'm looking into using merb to scale the file uploads on my Rails
website. I cannot afford to convert the whole application to merb
right now, so the Rails project and the merb app will coexist for a
while. For now, I'm looking into writing the simplest file upload
utility in merb. Here's what I have so far (code adapted from one of
Ezra's postings):
use_test :rspec
use_template_engine :haml
Merb::Config.use { |c|
c[:framework] = { :public => [Merb.root / "public", nil] }
...
}
Merb::Router.prepare do
default_routes
end
uploader = Proc.new do |env|
request = Merb::Request.new(env)
if request.path =~ /uploads/
params = request.params
FileUtils.mv params[:file][:tempfile].path, Merb.root /
'uploads' / params[:file][:filename]
[200, {}, 'ok']
else
[404, {}, 'not found']
end
end
merb = Merb::Rack::Application.new
If I try to upload a file to the merb app (curl -F
"[email protected]" http://localhost:4000/upload), it will complain
about "Controller class not found for controller `upload'". I
obviously don't know how to use the router section. What do I need to
do to make it work? Or better yet, how can I identify that the params
contain a multipart form and/or an attached file?
I have a second question: is the very_flat app type the lightest merb
app that one can create? I need to make sure it has a really small
memory footprint, as it will need to serve many, concurrent, large
file uploads.
Thanks a lot,
Tiberiu
