Hello There:
I am trying to do a deep cascading deletes in rails.
The schema looks like this:
Blogs (has many) entries ( has many ) comments
A blog has n entries, an entry has n comments.
So, in my Blog model I use
has_many :entries, :dependent => :delete_all
and in my Entry model I use
has_many :comments,:dependent => :delete_all
The problem I am having is that deleting blogs, will only delete
entries, but will not delete comments. In other words, the cascading
delete isn''t deep?
Am I doing something wrong here?
Thanks
Hilal

Hi Hilal, You need to use :dependent => :destroy instead of :delete_all because :delete_all doesn''t fire any callbacks. That''s why it only deletes one level. /Lasse 2010/4/2 Hilal <hilal.shaath-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>> Hello There: > I am trying to do a deep cascading deletes in rails. > > The schema looks like this: > > Blogs (has many) entries ( has many ) comments > > A blog has n entries, an entry has n comments. > > So, in my Blog model I use > has_many :entries, :dependent => :delete_all > and in my Entry model I use > has_many :comments,:dependent => :delete_all > > The problem I am having is that deleting blogs, will only delete > entries, but will not delete comments.
