Thanks Fred for your reply.

I modified with the following , but i get only the last value.

def dispfriends
@myfriend=[]
@myfriendlogin = []

i=0
@currentgroup = Group.find_by_id(params[:groupid])

puts @currentgroup.id

@currentfriends=
GroupFriend.find_all_by_user_id_and_group_id(current_user.id,
@currentgroup.id)

for n in @currentfriends
@myfriend=n.friend_id
@myusers = User.find_by_id(@myfriend)
@myfriendlogin[i]=@myusers.login
puts @myfriendlogin[i]
i=i+1
end

respond_to do |format|
# format.html { render :partial => 'users/dispfriends', :locals =>
{:user => @myusers}}

format.html { render :partial => 'users/dispfriends', :collections =>
@myusers}

end

end

Im very new to rails please help me in modifying my controller.

Thank you.
