Hello,

I'm trying to extract data from two related tables and send only specified fields to a method that creates a csv export. The problem is when send the data from the find method, only some of the fields match up in the export and are actually exported. I really only need to export the email, phone, and organization fields from the users table and the first_name, last_name, and expire_on fields from the accounts table. Accounts belongs_to the users table via the user_id.

Code:
    @account_all = Account.find(:all, :select => 'accounts.*, users.email, users.phone, users.organization', 
                                :conditions => @conditions, 
                                :joins => "LEFT OUTER JOIN users on users.id = accounts.id" , 
                                :order => 'accounts.created_at DESC')
I tried to scrub the fields I needed using the collect method:
Code:
    @format_account = @account_all.collect do |account|  
       account.first_name = account.first_name
       account.last_name = account.last_name
       account.phone = account.phone
       account.email = account.email
       account.organization = account.organization
       account 
    end if @account_all
here's the method call and export
Code:
@account_keys = ['first_name', 'last_name', 'phone','email', 'organization']   

    csv_string = format_faster_csv(@format_account, @account_keys)   
    send_data(csv_string, :type => 'text/csv; charset=iso-8859-1; header=present', :disposition => "attachment; filename=exported_accounts.csv")
Here's the export method:
Code:
  def format_faster_csv(csv_array, fields=csv_array.first.keys)
    csv_string = FasterCSV.generate do |csv|
      csv << fields.map {|f| f.titleize}
      csv_array.each do |row|  
        csv << fields.map{|f| row[f]}
      end
    end
  end
Any idea what I'm doing wrong?
