Hi, I am a bit of a rails novice and trying to work this out. Been
tearing my hair out over this for a long time.
I have 2 models that I am working on at the moment. The idea is that
Teams have many players and Players have many teams. I want to be able
to assign a starting team to a player when they are created.
class Team < ActiveRecord::Base
has_and_belongs_to_many :players
class Player < ActiveRecord::Base
has_and_belongs_to_many :teams
*Note: I have set up the correct join table and can insert these
relationships from the ruby console. *
At the moment I have this in my view:
<%= select(:player_id, :teams, Team.all.collect{|s| [s.name, s.id]})
%>
It collects all the team names however when I hit submit nothing is
sent. Am I missing out something?
Thank you. I have spent ages trying to sort this out.

Am I missing out something?Do you mean f.select( :player ...) rather than just select? Assuming you are inside a form_for that is.

Hi, thanks for your reply. I am indeed that a form_for. When I put an f. infrount i get an error. undefined method `merge'' for [["1st Team", 1], ["2nd Team", 2]]:Array Just to confirm. Without the f. the form loads however no Team data gets sent to the Params on the create.

This does not work. Using your code from before: <%= collection_select(:players, :teams, Team.all, :id, :name, :prompt => true) %> The form now submits however: *NO DATA IS SAVED IN THE JOIN TABLE IN THE HABTM RELATIONSHIP. * -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Have look at the Rails Guide on debugging to find out how to debug the code. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
