I am trying to implement HMT for the first time and having a ton of trouble. I would like to be able to have the user check a checkbox and fill some extra fields for data input.

I am trying to create a sortable list that is submitted not with an AJAX call but by a standard form submit button. Right now I have def reorder_group_members @group = Group.find(params[:id]) @group.group_members.each do |member| member.position = params[:memberlist].index(member.id.to_s) + 1 #I get a nil error for this line.

Hello list! I've been trying to list the users from a group of my samba server (running on an OpenBSD 4.2 box) by using "net rap groupmember list GROUPNAME -S PDC -U administrator%password -w DOMAIN", but I get nothing in return. By running the command with a -d for debug purposes, I get the messages above:

Or am I barking up the wrong tree here? -- Posted via

Hi, What''s the difference between attr_accessor and attr_accessible? Is attr_accessor to create a virtual variable/object and attr_accessible makes it accessible?
