Question

When I run the rails app on the production server, it gives me the following error:

NameError in LigesController#export_all

uninitialized constant LigesController::FasterCSV

However, in the development environment its working fine. This gem is already installed on the server. I can see it by "gem list" Any ideas???

Answer 1

I had this export all action in my controller. earlier instead of file I was using CSV, that gave me NameError. So i changed it to file and it worked. I dont know why we cant name it to csv..might be because of old csv gem…

def export_all

@liges = Liges.all

**file** = FasterCSV.generate do |line|
  cols = ["ID","Details","PartnerCode","Sence","Date","Partner","Person","TaxName","TaxID"]
line << cols

@liges.each do |entry|                
line << [entry.id, entry.description, entry.code, entry.ellipsis, entry.Date, entry.name, entry.people_name, entry.tax_name, entry.tax_id ]
    end  

end

send_data(file, 
:type => 'text/csv; charset=iso-8859-1; header=present', 
:disposition => "attachment; filename=Oligo_data_#{Time.now.strftime('%d%m%y-%H%M')}.csv")


 end
