search for: nullifying

...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 nullified, not deleted. The behaviour I''m seeing seems to be a hang over from when setting :dependent always meant ''delete/destroy the child...

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

Let''s say I have: A BELONGS_TO B B HAS_ONE A (with :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

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

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?

I've been using realtime for sip users information. I noticed that when you are doing this, if you do a 'reload' or restart asterisk, the information in a 'sip show peers' goes away. When I do this, MWI stops working. I always though MWI used the astdb file ('database show') to determine where to send MWI but it must be using 'sip show peers' because when this

In these days I’ve integrated llc code into my compiler. I had an undefined behaviour because when cl::AddExtraVersionPrinter(TargetRegistry::printRegisteredTargetsForVersion) is called, the modules I give to the code in input to compile got somehow “corrupted" by this function. It is definitely an undefined behaviour because every debug I do, modules gets different changes, producing

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 statements be removed? This in syslinux-3.81-pre2. Regards,...
