Question

I am using csv to export data. I am dynamically populating the fields and in order to do so i have added loop in to csv:

csv_data = CSV.generate do |csv|
  csv << [
  @userHeaders.each do |user|
    "#{user.name}"
  end
  ]
end

but this returns some thing like this: [#<User >, #<User >, #<User >, #<User >]

but when i tried to inspect the value after assigning it to a variable, it displays all the names that have been passed.

name = "#{user.name}"
puts name.inspect  # (this diaplays all the names)

is there any format to display the data while looping inside csv?

please guide with answer
thanks

Try just using the map (aka collect) method of your array:

csv_data = CSV.generate do |csv|
  csv << @userHeaders.map { |user| user.name }
end
