Need some info regarding "how to add friends"

[gow]

hi every one,

i’m new to ruby on rails.so, need some help.

my project is that a user can add friends to his profile where friends
are users themselves.

i thought of creating two tables one for users and other for
user_friends.i don’t know how to relate these two tables so that they
serve my purpose.

any suggestions plz.

thanks in advance.

I am also new but I think you just need to add to Users model:
has_and_belongs_to_many :users.

check out self referential associations - it is exactly what you are
looking for.
the problem with doing has_and_belongs_to_many :users, is that you will
still need a join table that ‘holds’ these associated records.

give it time, it looks daunting at first, but it works.
a couple links:

i worked with this

• http://blog.hasmanythrough.com/2006/4/21/self-referential-through
  although it is clearly outdated, and there are probably better things
  out there.
  i also googled for a sec, and found

http://lists.rubyonrails.org/pipermail/rails/2006-February/021193.html

• http://blog.dnite.org/2007/6/8/howto-has_many_friends
  (same plugin)
• http://blog.dnite.org/2007/3/14/has_many_friends-released

anyway … check out google for self_referential; that’s the way to go.
hope this helps!
