Is there a perl equivalent of .= in ruby/rails??
I want to make a for loop that concats strings onto a variable: html .= var1 + "this is a test" + whatever What is the syntax that does this in ruby/rails? Also, is there a ''print'' method in ruby? Because when I try to use render_text it will only let me use this once. -- Posted via http://www.ruby-forum.com/.

Deleting join association of has_many :through
I''m trying to use has_many :through, since my join model deserves being more than just an intersection table. But when I try to break the association, the break only seems "temporary": Let''s say my two tables are Users and Colors, and the join model is Favorites. user = Users.find(1) user.colors.length >> 2 c = user.colors.first >> #<Color:....>

prevent orphan records
If I have belongs_to :user Do I need to have validates_presence_of :user_id ? Does Rails validate the presence of :user_id automatically if I have belongs_to :user? In other words, does Rails prevent against creating orphan records that belong to non-existent users? Thanks. -- Posted via http://www.ruby-forum.com/.

Hi there I need to store additional attributes on join table. Searching the Wiki [1] revealed two possible methods: 1) push_with_attributes, as described by Justin Palmer [2]. Unfortunately, "this method is now deprecated" [3]. Even if it wasn''t, there seem to be inherent problems with that approach, for example with updating those additional attributes, though Joshua Muheim
