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:

\<%= error\_messages\_for :guess %\>

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

 \<%= game.home\_team.city %\> \<%= game.away\_team.city %\> \<% end %\> Save your predictions

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?

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
