setting up the SQLite database
...create
AppName::Models.create_schema
end
3.1 delete it after the db is created on the first run?
3.2 check if the db already exists (best way, please)?
3.3 check like this (never understood '':assume''?):
AppName::Models.create_schema :assume => (AppName::Models::
table_name.table_exists? ? 1.0 : 0.0)
or could we do something simpler like (?):
AppName::Models.create_schema unless table_exists?(table_name)
?

Why does AR use base_class for polymorphic relationship "type"
...lass that then
inherits from AR.
When they are used in a polymorphic relationship the "type" is always
the base class.
Just curious if anyone has a reason why it doesn''t use the *actual*
class rather then the base_class. I have patched AR to use the actual
class if !base_class.table_exists? but it adds another query each time
(which in turn fails some of the rails tests).
My only guess was for use with STI, but even then I am not sure if
there is a better solution then using the base_class

Rails 4.0.0.rc1 - A copy of <class> has been removed from the module tree but is still active!
.... The error goes away
after restarting the server but if I made a code change again and send a
request, the error would appear again.
This is what is in development.rb for reloading Reference::Base.

+ migrations in camping
Camping apps are supposed to be little independent apps, often contained in a
single file, which create the database tables and manage them without hassle.
These days it''s common to see in a Camping app:
module Tepee::Models
def self.schema(&block)
@@schema = block if block_given?
@@schema
end
end
Tepee::Models.schema do

Serialized object behaves weird
Hi!
I got a class named EinsatzFilter which I serialized to session. Before
saving to session it works afterwards I keep getting the message:
"undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from
ActiveRecord::Base inherited class.
Code:
class EinsatzFilter
