Rails - Feb 2008 - Validations not working - model mixup?

Hi there,

I''ve got a list of games, and users can guess the score of each game.
The guesses are appropriately sent to guesses_controller.rb, but I
can''t
get any of the validations in guess.rb to work. Here''s what I have in
the view:

<form method="post" action="/guesses/create" >

<%= error_messages_for :guess %>

<% @games.each do |game| %>

<tr>
  <td><%= game.home_team.city %></td>
  <td><input type="text"
name="home_score_<%=game.id%>" size="1"
/></td>
  <td><input type="text"
name="away_score_<%=game.id%>" size="1"
/></td>
  <td><%= game.away_team.city %></td>
</tr>
<% end %>
</table>
<button type="submit" class="button positive">
  Save your predictions
</button>
</form>

My model has this:

validates_numericality_of :home_score, :away_score

Is it because the guesses are called home_score_x and away_score_x?

Why aren''t you using the Rails helpers for your text fields?

<input type="text" name="away_score_<%=game.id%>"
size="1" />

Can be done as: <%= text_field "guess",
"away_score_#{game.id}" %> and the
other one like wise.

I would like to see your controller code before I can say anything more
(especially the part where you create the guess)

Here''s the relevant controller code:

guesses_controller.rb:

  def create
    params.keys.select {|k| /home_score/.match(k)}.each do 
|homescore_key|
          game_id = homescore_key.scan(/\d+/).first.to_i
          homescore_val = params[homescore_key]
          visitingscore_key = "away_score_#{game_id}"
          visitingscore_val = params[visitingscore_key]
          guess = Guess.new(:game_id => game_id, :home_score => 
homescore_val, :away_score => visitingscore_val)
          guess.save
    end
    ...
  end
