I''m sure I''m not getting something. I have Users, and I have
Groups.
Each User has_and_belongs_to_many :groups and each Group
has_and_belongs_to_many :users.
When I add a user, I want to apply a bunch of groups (like tags) to the
user (manually, without acts_as_taggable).
Here''s User#create:
@user = User.new(params[:user])
@user.groups = params[:user][:group_names].split(/\s+/).collect do
|group|
Group.find(:first, :conditions => ["name = ?", group]) ||
Group.new({:name => group})
end
@user.save
Groups that have not yet been created are created and their associations
to the user are saved in groups_users. Groups that already exist,
however, are *not* added to groups_users.
The further oddity is that User#groups=() does add previously existing
Groups, *if* I call it on a User object that has already been added to
the database.
Here''s an entry from the logs:
before save, groups=[#<Group:0x40710a9c
@attributes={"name"=>"one",
"id"=>"1"}>, #<Group:0x4066e654 @new_record=true,
@attributes={"name"=>"eight"}>]
This Group gets added:
#<Group:0x4066e654 @new_record=true,
@attributes={"name"=>"eight"}>
This Group does not:
#<Group:0x40710a9c @attributes={"name"=>"one",
"id"=>"1"}>
Why? Validation? I checked and there''s no errors before or after the
save.

not sure if this is your problem or not but if you are using Rails 1.0 this might be your issue. http://dev.rubyonrails.org/changeset/3332 -- Posted via http://www.ruby-forum.com/.
"Fixed that saving a model with multiple habtm associations would only save the first one." Hm... the description doesn''t sound like my problem, but I guess it could definitely be a bug in rails. Is it possible to get a newer version of the gem? Or do I need to use svn to get an updated version? -Payton Rob Schultz wrote:> not sure if this is your problem or not but if you are using Rails 1.0 > this might be your issue. > http://dev.rubyonrails.org/changeset/3332 >
This sounds exactly like my problem: http://dev.rubyonrails.org/ticket/3692 This is similar: http://dev.rubyonrails.org/ticket/3604 As is this: http://dev.rubyonrails.org/ticket/3259 Looks like a recurring problem for lots of people. It looks like the solution is to manually patch activerecord... but is there a better way? -Payton Payton Swick wrote:> I''m sure I''m not getting something.

i haven''t done it yet but you can do this to get the the EdgeRails with all the fixs. http://wiki.rubyonrails.com/rails/pages/EdgeRails though not always an option if you are wanting to deploy an app. -- Posted via http://www.ruby-forum.com/.
Have you tried edge rails?

Yes! Revision 3332 makes it work! Wow, I spent a whole day assuming I had done something wrong there. Thank you guys. What''s the release schedule (if any) for activerecord? That is, any idea when this patch will be in the gem? -Payton Bob Silva wrote:> Have you tried edge rails? > > Looks like a fix has been applied. > > http://dev.rubyonrails.org/ticket/3244 > > > Bob Silva > http://www.railtie.net/ > > >>-----Original Message----- >>From: rails-bounces@lists.rubyonrails.org [mailto:rails- >>bounces@lists.rubyonrails.org] On Behalf Of Payton Swick >>Sent: Sunday, February 12, 2006 5:29 PM >>To: rails@lists.rubyonrails.org >>Subject: Re: [Rails] habtm doesn''t save old IDs >> >>This sounds exactly like my problem: >> >>http://dev.rubyonrails.org/ticket/3692 >> >>This is similar: >> >>http://dev.rubyonrails.org/ticket/3604 >> >>As is this: >> >>http://dev.rubyonrails.org/ticket/3259 >> >>Looks like a recurring problem for lots of people.
