Using JRuby / ActiveRecord-JDBC / PostgreSQL 8.1 I get jruby --command rake test (in /Users/stevel/Publisher) rake aborted!

In a Rails controller I set the scope on a model class in an around filter. I have defined expectations on the model classes, and ideally, I would add a further expectation for the scope. Is this already possible in some way? How would I go about adding support a scope expectation? Michael -- Michael Schuerig mailto:michael at schuerig.de http://www.schuerig.de/michael/

Hello, I have two ActiveRecord classes. One is Route the other is Waypoints. I have constructed an XML representation so I can use AJAX to create a Route with all waypoints in a single create call to RouteController. When I call Route.from_xml(xmlString) it is not returning an object - it''s leaving the object (@route) nil, but not erroring. Any ideas? Here''s some code:

Hi, I know that the AWDWR says to believe in magic and to not spend Xmas with people asking this question, but really how does it work under the hood? I was looking at the source code of crummy, and it seems that instance_variable_set and instance_variable_get may be part of the answer. Is there some resource on that or do I have to dive into Rails code? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups &quot...

I?m having a strange issue with nested routes though, and was wondering if anyone could shed some light on this?

Hi! If i have 2 tables i.e. product and images and product has_many images, image belongs_to product - how to create _form.rhtml, new/create and edit/update methods in product controller, so in a single form i can add one product and MANY (let''s assume for now that this number is fixed) images for this product?

So by default to get STI, I would have something like: create_table :items do |t| t.column "type", :string t.column "title", :string end But if I want to store those type values in a separate table, such that I have ... create_table :items do |t| t.column "item_type_id", :string t.column "title", :string

I have a couple forms that I''d like to be able to validate and automatically populate, but it shouldn''t be based on AR. In fact I often have a bunch of small forms that I can''t really justify writing a whole new model class for anyway. I''d like to validate the form input, and then use rails helpers to automatically populate the form if validations fail.

How can I find all the methods on an object from withing irb? Thanks, Joe

Hi all, I''m trying to move a bunch of methods out of a controller into a library that I can include and call a class method to have it dynamically add a bunch of methods to the controller. The goal is to just add to each controller: include UIEnhancements::SubList sub_list ''Note'', ''incomplete'' and have the sub_list method create all the methods

...red" (because rubygem Gem.path method caches the path on the first use, which is done by mongrel_rails). To make this work, I had come to this hack: ENV[''GEM_PATH''] = File.expand_path(''~/.gem'') require ''rubygems''; Gem.clear_paths; Gem.instance_variable_set(:@searcher, nil) Which clears the internal cache used by rubygems, and forces it to re-read the GEM_PATH env. variable. But I don''t fell comfortable using it... is there a better way to do this? Like, setting the GEM_PATH from the mongrel cluster config file? Best regards, Rui Lopes...

I''ve used wxFormBuilder to put a wxRichTextCtrl on my form. After doing this, I run xrcise and try to use the control. The variable for the rich text control is a FixNum. On examination, I saw that the class name in the xrc file is "unknown". Is there no way to use this control without manually laying out the controls - or writing this routine in C++?
