Hello,
I have an application that should be able to export a list of users as
CSV.
So I put
Mime::Type.register "text/csv", :csv
into my environment.rb, and added this code to my UserController''s
index
action:
format.csv do
require ''csv''
CSV::Writer.generate(csv_string = "", '','')
do |csv|
csv <<
["login","attribute1","attribute2"]
@users.each { |user| csv << [user.login, user.email] }
end
send_data csv_string, :filename => "users.csv"
end
All this is working fine, but each time I start my "ruby
script/console", I get the following error:
./script/../config/../config/../vendor/rails/actionpack/lib/action_controller/mime_type.rb:48:
warning: already initialized constant CSV
The error disappears, as soon as I remove the Mime Type entry in the
environment.rb. But of course this breaks the CSV export action.
So the app is behaving fine, but what causes the error and how can I get
rid of it?
