   Good news! Does it happen to include support for signature version 0 to overcome the UTF8 problems in SDB?

   Juergen, I’m afraid not. We’ve been busy absorbing all the changes… A patch would be very welcome though

   Alright, I see what I can do. Currently I have simply overwritten the method in question to always use signature version 0. I try to make it more configurable.

   I posted this on rubyforge also. Feel free to respond in either place (but please cc: my email if your forum comments here won’t do that automagically).

   Hi,

   Just testing out ActiveSDB. I am wondering if my usage pattern is the most efficient?

   I setup my table like this:

   RightAws::ActiveSdb.establish_connection(“KEY”, “SECRET_KEY”, :logger => Merb.logger)
   Post.create_domain
   Post.create :title => ‘An SDB Blog Title’, :body => ‘Some really nice body text.’, :created_at => Time.now

   In my posts controller I have something like this (I am using Merb BTW). I did it this way since it was the only way I figured out to get the collection in a way that I could actually access it in my views:

   app/controllers/posts.rb
   –
   def index
   @posts = []
   Post.find(:all).each do |post|
   post = post.reload
   @posts<< post
   end
   display @posts
   end

   Is this the best way to send a collection of found items to the view? This #reload method is not really clear to me (and feels like something that should be handled by the lib instead of called every time. no?).

   Also, When accessing this collection from the view it feels very clunky. The strings I stored (see above) are returned (always) as an array. Is this fundamental to SDB? I find I have to do things like this in my view to access an attribute which is not very pretty:

   post['title'][0]

   And lastly when accessing an object should’nt I be able to also get it with a symbol like:

   post[:title][0]

   This fails with an error (its returns a nil)…

   Please set me right if I am missing something.

   Thanks,

   Glenn

   Hi. I heard your good news(http://gigaom.com/2008/04/23/rightscale-takes-45m-for-the-cloud/).
   I’m using your gem for SimpleDB, and wrote this post(http://flyingmate.net/46). Although it’s written in Korean, you can understand the code of ActiveItem(named temporarily) at the middle of the post.

   That code snippet helps using SimpleDB similar to ActiveRecord, for example, you don’t need to change controller codes and view codes for using RightAws::ActiveSdb. It wraps your attribute method like [] and []= with accessor method like #{attribute_name} and #{attribute_name}= for convenience. Action View’s form_for helper use #{attribute_name}= style methods in default, and can not recognize []= style methods. If developer use form_for method without changing form_for helper with RightAws::ActiveSdb, undefined method #{attribute_name}= error occurs.

   So I suggest that implement your code with #{attribute_name} style method. In advance, I hope RightAws::ActiveSdb supports validations and associations like ActiveRecord.

   Thanks

   Sung Hoon
