Method: SimpleRecord::ActiveSdb::Base#reload_attributes

Defined in:
lib/simple_record/active_sdb.rb

#reload_attributes(*attrs_list) ⇒ Object

Reload a set of attributes from SDB. Adds the loaded list to in-memory data. attrs_list is an array or comma separated list of attributes names. Returns a hash of loaded attributes.

This is not the best method to get a bunch of attributes because a web service call is being performed for every attribute.

item = Client.find_by_name('Cat')
item.reload_attributes('toys', 'name')   #=> {"name"=>["Cat"], "toys"=>["Jons socks", "clew", "mice"]}
