Assuming all your associations are setup right, you should be able to do the following. # in journals controller, this will return the current users journal def show @journal = @current_user.journals.find( params[:id] ) end # adding a new journal for the current user # example, instead of doing something like: @journal = Journal.new( params[:journal] ) if @journal.save .... You can do the following: @journal = @current_user.journals.new( params[:journal] ) if @journal.save ... By using the associations, you'll be able to add associated data to the current user without much extra work. Hope that helps!
