undefined method `quoted_table_name' with model called "schema"
Rails seems to have a problem with any model called Schema, when another model has a has_and_belong_to_many relationship with Schema.
Generate two scaffolds, one of which has a model called Schema. Generate a migration for a join table, including box_id and schema_id columns. Add has_and_belongs_to_many calls to the models.
Run the migrations and start the server. Create a record of the non-Schema type. Try to destroy that record. The server fails with an error message like:
NoMethodError (undefined method quoted_table_name' for
#<ActiveRecord::ConnectionAdapters::SQLite3Adapter:0x2470624>)

Dan Pickettnot reproducible
I was able to create a new rails app with a schema model and a user model - upon creating and destroying a user I did not get any errors

Behavior verified on 2-3-stable.

-1 The error stems from a reflection instance returning ActiveRecord::Schema (rather than regular Schema) as klass.
As a work around, use:
class User < ActiveRecord::Base
has_and_belongs_to_many :schemas, :class_name => "::Schema" end -

-1 It is evident that ActiveRecord will have problems with tables that have matching names to its internal classes.
