On Rails 2.1.1, I have this simple case:
class Post < ActiveRecord::Base
has_many :comments
end
class Comment < ActiveRecord::Base
belongs_to :post
validates_presence_of :post_id
end
Now, when building associated comments to an unsaved post, the
validation fails:
p = Post.new
=> #<Post id: nil, name: nil, created_at: nil, updated_at: nil>
c = p.comments.build
=> #<Comment id: nil, text: nil, comment_id: nil, created_at: nil,
updated_at: nil>
c.valid?
=> false
c.errors
=> #<ActiveRecord::Errors:0x23f8d18 @base=#<Comment id: nil, text:
nil, comment_id: nil, created_at: nil, updated_at: nil>,
@errors={"post_id"=>["can't be blank"]}>
According to http://dev.rubyonrails.org/ticket/4147,
validates_presence_of the foreign key is the proper way to validate
the presence associated objects. However, the documentation warning
regarding this was later removed.
So, question is: How do I validate the presence of associated objects,
while still allowing the building of associated objects to an unsaved
model?
