got a problem with one to one relations

I have some Matches and i want to have one score for a match.

Use build instead of new:

def new
    @match = Match.find(params[:match_id])
    @score = @match.build_score
end

Here are the docs for this: http://guides.rubyonrails.org/association_basics.html#belongs_to-build_association

Similarly, in the create method, do it like this:

def create
    @match = Match.find(params[:match_id])
    @score = @match.create_score(params[:score])
end
