Hi I''m working on a project that has users and groups, users can be members of a group *or* they can just be a user - what''s going to be the best way to deal with this? I understand the normal has_many relationship just not sure how to do this one. Will try to post some code snippets tomorrow.

If a particular member does not belong to a group then just leave group_id nil. You will obviously have to allow for user.group == nil in the code where appropriate. If he can belong to many (or no) groups then use has_many :through as Dave suggested. You can test user.groups to see if he is in any groups. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I was assuming (and you know what happens then!) that a User could belong to many Groups. -Dave -- Dave Aronson, the T.

Thanks Dave & Colin! That was how I had hoped it would work!

Here is an update, I have it working as only a group or as only a non-group
user. I have below the create controller and was wondering what would be
the best way to allow associations and non-associated records. Thanks
def create
if Group.nil?
@group = Group.find(params[:group_id])
@user = @group.users.create(params[:user])
else
@user = User.new
@user.ip_address = request.remote_ip
@user.ua_string = request.user_agent
@user = User.new(params[:user])
end
respond_to do |format|
if @user.save && @user.group_id == nil
format.html { redirect_to "/", notice: ''Thank you for
registering!''
}
elsif @user.save && @user.group_id != ""
format.html { redirect_to group_path(@group.token), notice:
''Thank
you for registering!'' }
else
format.html { render action: "new" }
format.json { render json: @user.errors, status:
:unprocessable_entity }
end
end

I''d recommend: if it saves redirect to (if it has a group, the group, else /) else give error msg end Also, look closely at the way you''re checking for a group. The first option will trigger if the group is nil, the second if it''s not "" (empty string)... but what if it *is* ""? That''s neither nil nor not-"", so it will take the "else" path and pretend like it didn''t save. I suggest you use .blank? (or its inverse, .present?) to tell if it''s there or not. Both nil and "" count as blank (and not present). -Dave -- Dave Aronson, the T. Rex of Codosaurus LLC, secret-cleared freelance software developer taking contracts in or near NoVa or remote.
