should pass table.engine in sanitize_sql_hash_for_conditions
Reported by bewang | December 22nd, 2010 @ 11:07 PM
class MyBase < ActiveRecord::Base
end
class Rule < MyBase
has_many :rule_associations
has_many :evaluations, :through=>:rule_associations,
:conditions => { 'join_table.column' => 'T' }
end
MyBase.establish_connection
ActiveRecord will fail in sanitize_sql_hash_for_conditions with error like
[INFO] undefined method `spec' for nil:NilClass (NoMethodError)

passing tabl.engine to b.to_sql fix the issue.
def sanitize_sql_hash_for_conditions(attrs, default_table_name = self.table_name)
attrs = expand_hash_conditions_for_aggregates(attrs)
table = Arel::Table.new(self.table_name, :engine => arel_engine, :as => default_table_name)
builder = PredicateBuilder.new(arel_engine)
builder.build_from_hash(attrs, table).map{ |b| b.to_sql *table.engine* }.join(' AND ')
end
