Hi all.
In my Rails 2.1 code (I am skipping 2.2...) used to do something like this from a reports controller:
render_proc = proc do |response, output| CSV::Writer.generate(output) do |csv| csv << [ 'Login', 'Name', 'Email' ] User.find(:all).each do |user| csv << [ user.login, user.name, user.email ] end end end
render :layout => false, :text => render_proc
This no longer works because CSV:Writer wants to call <<() and it is not defined.
Was this removal intentional?
As a side-note, it looks like other people seem to build the whole CSV as a string and then ship it at the end. Maybe my strategy results in the same behaviour under Rails unless I explicitly flush it somehow, in which case maybe I should just copy what everyone else is doing...
