Hello. LoginSystem is cool, it populates the @session instance variable of controllers with many useful info. The fact is : it would be cool to let models know about the session, too.

Hi there, I''m writing a little application that parses an image file and extracts the camera settings from the file (the EXIF data) and saves all the fields to the database.

How do you tell if an foreign key attribute has been changed? For example, lets say you have a model with attribute table_a_id. Would you do this? def table_a_id=(value) if value != table_a_id @table_a_changed = true write_attribute ''table_a_id'', value end end def table_a=(value) if value != table_a @table_a_changed = true

So my User model object is using has_many_and_belongs_to :topics and vice versa. I want to find all the topics that a user has *not* subscribed to. This is what I''ve got: @user = User.find(params[:id]) @topics = Topic.find(:all, :conditions =>
