It's very simple, I want to handle a normal [show] request with a call to DataMapper like I did in Merb. With ActiveRecord I could have done this: class PostsController def show @post = Post.get(params[:id]) @comments = @post.comments unless @post.nil? end end and it handles the 404 by catching the resource's exceptions. ...
Hi, I've recently built a fairly deep nested form using http:// github.com/timriley/complex-form-examples for guidance. The form partial uses the following in order to render new fields when a link is clicked: <%= yield :warehouses_fields_template %> <%= yield :ratgrades_fields_template %> The content for these is generated i...
I added a unit test manually to test a library I'm building. I have some fixtures which are tested in their corresponding models without any issues.

Starting a new web app with Rails 3. I'm still relatively new to web development and have really enjoyed all the internet resources available to me while working in Ruby 1.8.7 and Rails 2.3.5. Any advice against using Ruby 1.9.2 on my new project? ...
In rails 2.3.5 you could do something like this inside the routes.rb file: map.root :controller => "pages", :action => "show", :id => 3 In rails 3 I haven't found any way to pass a specific parameter (like in rails 2.3.5 with :id => 3). I know I can handle it from the controller and have the same result (which I did), but I was wond...

This is likely something easy to accomplish, but I'm having difficulty even articulating clearly, leading me to get all sorts of semi-germaine, but not quite what I'm after posts on SO when searching. I have a resource, we'll just use User as a simple to discuss use case. I desire SEO friendly URLs, so instead of ~/users/:id, we have ~...
