Hi everyone, A couple of weeks ago I noticed a bug with :dependent => :nullify on a has_many or has_one. When you delete the parent, the children''s foreign keys are nullified, as expected. But when you do parent.child.delete or parent.children.clear, ActiveRecord actually deletes the child records, rather than just nullifying them. In my eyes, if you''ve set :dependent => :nullify, you''re saying that the child records should only ever be nul...

If you have a model that has has_many :clients, :dependent => :nullify Will that run the save method for each client or will it just simply nullify the foreign key using straight SQL without every calling save. Because I have some very important before_save code in my Client model and I do not think it is getting ran. Thanks for your help. Thank You, Ben Johnson E:

Hi all, There is something confusing with has_many in the current API : When deleting a record with association.delete, the corresponding association''s foreign key is nullified. However, if has_many has the :dependent option set (to any value), the association''s destroy method is called instead. This is awfully inconsistent with the behavior expected when setting :dependent to :nullify. While browsing the Trac database, I found several patches submitted to add...

...th :dependent=>:nullify) But this association does not need to exist. In other words, I could have many A''s and B''s that are not associated in this manner. Presently, if I try to delete "B": 1. If B is associated to an "A", this works fine and A.my_B is nullified. 2. If B is NOT associated, I get an error saying it is trying to call "nil.update_attribute" (presumably trying to set the my_B to nil.) Seems to me this is a bug -- if my_B is already nil, nothing should happen; Rails should just happily delete B. Jake -- Posted via http://ww...

Currently, I'm looking to improve rosh and would like to start using getopt(). I'd like to parse a string obtained by fgets() to be like the argc/argv pair created by __parse_argv but in a way that's more cross-platform (such that it can also be used by .lnx files rather than just COM32) and suitable to use in rosh and lua.c32. I've made a function and inlined a test program for

...he actual xl and qemu processes are gone, so guest only seem to be still registered in the hypervisor. Another thing this seems to trigger (and that perhaps needs fixing) is that a "xl shutdown --all --wait" doesn''t wait anymore. It returns immediately, probably due to the "nullified" name ? -- Sander

Formally speaking blanking is not appicable to DVD+RW. dvd+rw-format -force merely zeros bitmap which describes which ECC blocks were de-iced/written to and nullifies few blocks in the beginning of the media. It's not what one would normally consider as [full] blanking. If you want to nullify the media, e.g. for privacy reasons, 'dvd+rw-format -force /dev/cd0c' won't do the tick, 'growisofs -Z /dev/cd0c=/dev/zero' would. > The probl...

Hi, Is there a way to use the :dependent option to set a certain attribute to null rather than destroying the records? For example, take the following models: User id, integer name, string group_id, integer belongs_to :democrats Groups id, integer name, string has_many :users If I delete a certain group, is there a way to have the ''group_id'' attribute of all the

Hello friends! I am trying to make a database that will have a group of people set to committees, and a person can be in multiple committees, and a committee obviously has multiple people. The people are senators at my university. These are my current models: senator.rb: -- class Senator < ActiveRecord::Base validates_presence_of :first_name, :last_name, :floor has_and_belongs_to_many

In my rails application,there are two models:post and catalog. One post has a catalog,and one catalog has many posts. When I delete a catalog,the posts belongs to the catalog will not be shown normal,for it''s catalog is no existed. Now I want to create(if the ''Defalut catalog'' is not existed) a ''Defalut catalog'' in catalogs table,and make the

One can perform a for loop without indices over the columns of a dataframe like this: for( v in df ) ... some statements involving v ... Is there some way to do this for rows other than using indices: for( i in 1:nrow(df) ) ... some statements involving df[i,] ... If the dataframe had only numeric entries I could transpose it and then do it over columns but what about the general case?

...ltime and instead provision users in sip.conf, a reload or restart DOES NOT clear 'sip show peers'. It must be populating this list from the astdb file in that case. I'm going to scoot over to bugs.digium.com and report this as a bug, because this is a real show stopper, and completely nullifies Realtime's use for us. Doug

...cing different assertions every run: - Target triple string gets changes with null characters (“\0\0\0\0\0\0\0\0\0\0\0”), or other values that have nothing to do with an llvm triple - Head of the function list contained in the module becomes NULL (I said functions but maybe other components may be nullified as well) I tried to see where the modules change, and I figured out that 6/10 times the target triple is ok before that instruction, then it takes weird changes after it. The problem is that function because when I removed it, everything worked fine. I didn't figure out how that function ma...

I am after a nice way to disable (not destroy, delete nor nullify) all associated records. I''m a hoarder, I don''t want to get rid of anything but I want to stop records being visible. I have a disabled boolean in my tables and if I disable the top record in the association (say the association is 5-6 levels deep), I would like to cleanly disable its children. I''ve

I have a user model that owns messages : class User < ActiveRecord::Base has_many :messages , :dependent => :nullify end I''m using nullify so that when the user is deleted, the messages continue to exist - they''re just marked as being ownerless. However, calling user.messages.clear actually deletes all his messages, which I was a little surprised at. I would

Hello, The main function in com32/modules/chain.c does a lot of argument parsing, finding the drivename, partition, seg, etc., for two statements nullifying most of the work: drivename = argv[1]; partition = argv[2]; /* Possibly null */ Seeing as the function initializes the variables correctly at the beginning: drivename = "boot"; partition = NULL; shouldn't these
