I'm about to add a Rainbows!-hosted file upload component to an existing application. At the moment I've got duplication between the app ("Note: maximum attachment size is 200MB") and rainbows.rb ("client_max_body_size 200*1024*1024") and am wondering if there's any way for the app to know what client_max_body_size the server is configured for so I can display a human-friendly version of that on the attachment page. (please cc: replies as I'm not subscribed to the list) cheers Russell _______________________________________________ Rainbows! mailing list - rainbows-talk-GrnCvJ7WPxnNLxjTenLetw@public.gmane.org http://rubyforge.org/mailman/listinfo/rainbows-talk Do not quote signatures (like this one) or top post when replying ^ permalink raw reply [flat|nested] 3+ messages in thread

Hi russell, There's no stable/official internal API, and there probably won't be. We try not to encourage propagating new, ad-hoc standards that other Rack servers do not support. Sometimes it's not easy to avoid (e.g. async.callback + EventMachine stuff), but we try. However, since the config file is Ruby, you can always use a global variable in your config file. > I'm about to add a Rainbows!-hosted file upload component to an > existing application.

So something like this: Rainbows! do client_max_body_size($client_max_body_size = 200*1024*1024) end If you have more variables you want to set, I know some folks that use a global hash object or Struct, too. > (please cc: replies as I'm not subscribed to the list) -- Eric Wong _______________________________________________ Rainbows! mailing list - rainbows-talk-GrnCvJ7WPxnNLxjTenLetw@public.gmane.org http://rubyforge.org/mailman/listinfo/rainbows-talk Do not quote signatures (like this one) or top post when replying ^ permalink raw reply [flat|nested] 3+ messages in thread

I wasn't sure what context the Rainbows! config was evaluated in and tried MAX_UPLOAD = 200*1024*1024 Rainbows! do client_max_body_size MAX_UPLOAD end and then referencing MAX_UPLOAD in my config.ru where app-wide stuff gets stuffed into Rack::Config but couldn't resolve that constant - rather than wading into looking at the scopes used for config evaluation I thought I'd just ask... rather than using global vars I've packed some constants into a Config module in my app and it's all good. thanks for the pointer! cheers Russell >> (please cc: replies as I'm not subscribed to the list) (now subscribed) _______________________________________________ Rainbows! mailing list - rainbows-talk-GrnCvJ7WPxnNLxjTenLetw@public.gmane.org http://rubyforge.org/mailman/listinfo/rainbows-talk Do not quote signatures (like this one) or top post when replying ^ permalink raw reply [flat|nested] 3+ messages in thread
