Confusion about the create_id

[hadmut]

Hi,
I'm having two apps using couch_potato, i.e.

• a very simple as a Rakefile just to test and learn how to use couch_potato
• a Sinatra application making real use of couch_potato.

I noticed that with the simple test app, the document entry determining the ruby class is named "ruby_class", like

"ruby_class": "User"

while in the more complex Sinatra application it is something like

"json_class": "User",

Although couch_potato.rb starts with
JSON.create_id = 'ruby_class'

it seems to depend on the order of libraries loaded, or other libraries seem to change it, however, it looks as if it could cause trouble when loading such documents.
