Hi all,
I have a has_and_belongs_to_many association, and define the delete_sql
myself.
Class A
has_and_belongs_to_many: b,
: delete_sql => ''.....''
end
Supposedly when A is destroy, the association record should be delete by
the delete_sql I define. But it seems that the delete sql will not be
overwritten.
Anybody works on this? Or I misunderstand the spec. ?
I checked the source code
activerecord-1.13.0/lib/active_record
def has_and_belongs_to_many(...
...
..
before_destroy_sql = "DELETE FROM #{options[:join_table]} WHERE
#{association_class_primary_key_name} = \\\#{self.quoted_id}"
module_eval(%{before_destroy
"self.connection.delete(%{#{before_destroy_sql}})"})
# "
..
end
It seems that the :delete_sql option is never taken?
Gary
