Hello, I''m trying to find a very abstract and "one size fits all" for converting nested active record results to nested hashes. It''s easy, to do one level deep as such: [code] results_to_hash = Hash[ found_categories.map{ |c| [c.id, c.title]}] [/code] But, when I try to add another collection to the mix, it completely borks and the results_to_hash only returns an

Hello, I have a question. I would like to know if there is a way with the reflection and respond_to? to know if there is a relationship between tables. When I say that I mean if inside a model there is a Has_many or belongs_to declaration. Because I try to get this information dynamically, during the execution of a script. If someone has an idea even if it''s not with the reflection,

Still new to Specs... How do I create a spec to test a model method?

Regarding validates_associated... Let''s say I have: article belongs_to author But for whatever reason, I want an article to also be written anonymously and therefore not require an author. Then I have: Article: belongs_to :author validates_associated :author But I DON''T have validates_presence_of. What I want to do is validate that an author is valid --if it is

This is pretty much the same as last time around, if you recall. Thanks to Wilson for converting to the new form. I''ve added a few lines. Basically, it iterates over your model associations and does two things. - First, just try to call the association. Usually fixes speeling erors or other such silliness. - Second, try to find a record with an :include on the association. This

Hi all, I''ve forwarded the following question from Steve Tuckner. Any ideas? From Steve - "I found this open source telnet server that I modified for my own purposes to run programs through telnet and display them in my own ruby console.
