Problems w/ selecting model data in the right order



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.

    @account_all = Account.find(:all, :select => 'accounts.*,,, users.organization',
                                :conditions => @conditions,
                                :joins => "LEFT OUTER JOIN users on =" ,
                                :order => 'accounts.created_at DESC')

I tried to scrub the fields I needed using the collect method:

    @format_account = @account_all.collect do |account|
       account.first_name = account.first_name
       account.last_name = account.last_name = =
       account.organization = account.organization
    end if @account_all

here’s the method call and export

@account_keys = ['first_name', 'last_name', 'phone','email',

    csv_string = format_faster_csv(@format_account, @account_keys)
    send_data(csv_string, :type => 'text/csv; charset=iso-8859-1;
header=present', :disposition => "attachment;

Here’s the export method:

  def format_faster_csv(csv_array, fields=csv_array.first.keys)
    csv_string = FasterCSV.generate do |csv|
      csv << {|f| f.titleize}
      csv_array.each do |row|
        csv <<{|f| row[f]}

Any idea what I’m doing wrong?


Your join is wrong. Should be ON = accounts.user_id
