Question

I have nested controller Reviews under Users, both generated by scaffold generator; view/index actions works well, but when I’m trying to create model (/users/1/reviews/new) there is an error

No route matches {:controller=>"reviews", :user_id=>#<Review id: nil, user_id: nil, reviewer_id: nil, predisposition: nil, description: nil, created_at: nil, updated_at: nil>}

I’ve tryed to change form_for @review to form_for user_reviews_path(@review), but there is the same error on create action.

How can I fix this trouble?

Also I’d be grateful if you suggest me book about Ruby On Rails recipes (I’ve read ROR recipes from pragmatic, but it is too simple).

Answer 1

In your controller:

@user = User.find params[:id]
@review = @user.reviews.build(<enter your initialization params here>)

In your view:

=form_for [@user, @review] do |f|

I would start with the excellent http://ruby.railstutorial.org/ and of course http://railscasts.com
