Camping list - Aug 2006 - Camping with Dr. Nic

Campers.  Dr. Nic.

The new migrations in Camping''s trunk are very nice.  They also open  
the door (just an inch) to using Dr. Nic''s Magic Models with Camping.

Here''s my stab at ''er:
   http://require.errtheblog.com/camping/blog.rb

Run that against Camping trunk.  Don''t forget to `sudo gem install  
dr_nic_magic_models`.

The hackery is in Blog.create.  Have to dance around Camping''s meta- 
ness and table prefix stuff.  Anyone have a better / easier way of  
doing this?  I tried a few different approaches but kept coming back  
to this one -- the brute force.

Either way, it works.  Maybe this is a candidate for Equipment,  
Jonas?  Enjoy.

Actually, this would be nice to have around in camping/db.rb.

  if Object.const_defined? DrNicMagicModels
    DrNicMagicModels::Schema.module_eval <<-LOAD
      def self.load_schema
        if conn = ActiveRecord::Base.connection
          @@models = DrNicMagicModels::ModelHash.new
          @@models.merge! conn.tables.inject({}) {|model_list,table_name|
           
model_list[ActiveRecord::Base.class_name(table_name.split(''_'')[1..-1]*''_'')]
table_name; model_list}
        end
      end
    LOAD
  end

Play with it for another week and let''s see if it holds up.  If
it''s just 12
lines, then yeah.
