Is this a copy-paste error? s/b attachments_reminders (both plural), right? > through migrations and it has reminder_id and attachment_id fields. > > In controller I need to copy a record in attachment table and save it in > Attachment table.

If you add attachments to the @reminder.attachments collection, when you save the @reminder, the attachments will be "attached" automagically. The inverse is also true. You can create new attachments on the reminder by calling @reminder.attachments.build( any arguments here ). > can I achieve it.

If you have properly defined your habtm relationship (including correctly-named table) then nothing about this has to be declared like this. You don't need to test for post?, you don't need to do anything besides create or update the main object in your controller, just as if it didn't have any attachments. When you save the main object, all of its related objects are created, updated, saved -- whatever they need. > rec.save > end > flash[:notice]="Reminder updated successfully" > redirect_to :controller=>"reminde", :action=>"view_reminder", > :id2=>params[:id2] > end > Walter -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
