Surprise in (delete_all | clear | destroy_all) on association
Hi,
I was very surprised by difference of delete_all on association vs
model(delegated to relation).
Given TaskFilter.has_many(:qualifiers, :class_name=>''TaskFilterQualifier'')
TaskFilter.delete_all => one DELETE statement
Without :dependent option on "qualifiers" association
TaskFilter.first.qualifiers.delete_all =>
SELECT `task_filter_qualifiers`.* FROM
