Hi guys, When I export data into a .csv file, it works perfectly. when
I push the code to heroku, I get the following error:
ActionView::Template::Error (can't convert Hash into String):
My helper to generate the csv is:
def generate_csv
csv_str = CSV.generate(:col_sep => ",") do |csv|
Entrant.find(:all).each do |entrant|
csv << [entrant.firstname, entrant.lastname, entrant.email,
entrant.entrydate]
end
end
end
Is there any reason why I would get this error?
Thanks in advance for your help.
