Is ActiveRecord going to assume that there is a table behind these guys? If so, how do I indicate that these attributes are not

The new "pending" example feature reminds me of a feature I''ve been bouncing around in my head, to aid in refactoring.

Hi, i have a "place" model with 2 columns (id, name). I''m calling an external api which gives me data to create a new place object.

There are areas of my application that "want" to use a url structure like domain/<human_readable_param>/<Module>/<Controller>/<Action>/<Id> Please note that the human readable parameter I need to inject is NOT related to the <id> being used by the action/controller pair.

Hello How can I test equality with two objects when they include some attribute that is BigDecimal? if I make something like this: it "should ...whatever" do obj = Factory.create(:my_object) ... MyObject.first.should == obj end. FAILS This fails because the object expected is different from the object gotten, and the only difference are the BigDecimal attributes, that are

I have some properties that I want setable externally, but readable only internally. I''ve played around with attr_writer (and attr_reader separately) but can''t figure out how to get either to work. I can do what I want using attr_accessor, or just straight out defining the prop setter method. Anybody know how to use attr_writer or attr_reader with a model? You da man, Joe
