I am running Rails 1.1.2 with Ruby 1.82-15. My database is Postgresql. I haven''t had any problems generating models, migrations, using scaffolds, and generally building and using my application, but I haven''t been able to get testing to work.

As far as I can tell, the counter_cache option on a belongs_to model doesn''t actually save anything in the database. For example, I have the following models: class Parent < ActiveRecord::Base has_many :children, :conditions => "deleted_at IS NULL" end class Child < ActiveRecord::Base belongs_to :parent, :counter_cache => true end With the following

Is there a way to use validates_numericality_of and still allow null values? I have a model with some optional values that can be nil, but if they''re present, they must be numbers. Will I need to construct a custom valiation for this, or is there some method built in? Seems like it would be a common enough need. Jeff -- Posted via http://www.ruby-forum.com/.

Before I file a ticket, I''ll query ya''ll about this: The API docs for acts_as_tree''s counter_cache is to create a database column called "children_count" to hold the counter_cache. I have enabled this option in my model. While writing tests I wrote a test for creating children from the a parent: message = @forum_message["parent"].find child =

Running ruby script/generate scaffold Product Admin is a wonderful way to set up well, exactly what it says, a scaffold. My problem is that I have several other tables that are linked, through foreign keys, to the Product table. Say an "authors" table.

I am a bit confused about counter_cache here. The API docs http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html say that only the belongs_to association can take the :counter_cache option. When I try to use it on a has_many I get an "unknown key(s): counter_cache" error. Why would this be the case? belongs_to means that this model has a field with an id
