Hello, I''m a bit stuck with where to put some method calls (separation of responsibility) and although I''m trying to do it just simply now in the models, I think my problem raises a bigger question about Fat Models. But that''s another subject for another day. Right now, I have .... Event has_many meetings ## has an a invitation_expiry date field. def

Given the following class Programmer < ActiveRecord::Base has_many :assignments has_many :projects, :through => :assignments end if I call Programmer#projects.clear, it will delete_all the joining assignments; however, I have a situation where I''d like the assignments to get destroyed instead so that their after_destroy callbacks get called. It would be simple to

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

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

We have a test that has been working find until we upgraded to rails 2.3.5. I''m not too familiar with mocks/stubs so maybe there is an easy solution. Here is a simple example of our scenario. Class Person < ActiveRecord::Base has_many :aliases, :dependent => :nullify before_destroy :mark_aliases_as_deleted def mark_aliases_as_deleted self.aliases.each do

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

Hi, While I was hacking ovirt-server, I have found that it's currently restricted to Postgres DB. Even if I like postgres for serious work on a server, I really prefer to hack/dev locally on a Sqlite or MySQL DB. I have googled on rails in order to find a good answer for the "foreign key problem" which forces OVirt to stay on pg. I have found a plugin on this particular

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

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

I have 2 models SmsAddress & OutboundSmsAtom SmsAddress { has_many :other_objects, :dependency => :nullify } OutboundSmsAtom { #note this object also "belongs_to" other objects if that matters belongs_to :this_object } Whenever I try to destroy an object of type ThisObject, which at the time has 0 "children" OtherObjects I get the following type of

I''m playing around with some legacy schemas; ones that make extensive use of foreign key update/delete rules. I''ve been working through a variety of cases to understand how different configurations within Rails will play with the DB. If the delete rule is Cascade and :dependent=>false, deleting the parent deletes the children, exactly as the DB rules specify and do so

I have a Deck object and a Card object with their corresponding tables. (You know a deck of cards.) When I destory a Deck it leaves orphaned cards in the database. Is there a way to set up the objects with ActiveRecord so that when a parent object is destoryed the child objects are destroyed as well? My code below. class Deck < ActiveRecord::Base has_many :cards end class Card <

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:

Hello, Anybody help me out? I done googled it good and didn''t find anything (which should mean that I''ve done something wrong). Not much code to talk about here, quite simply I have an attribute that is serialzied and when I update it, irb shows the object and my methods run on it as it were indeed so. Though when I reload it changes the data to a string. Not yaml, just one

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

Hello, I am having some problems understanding a few concepts in Samba while trying to use samba-common-3.0.0-14.3E, samba-client-3.0.0-14.3E and samba-3.0.0-14.3E on RHE 3.0. Basically, I have security = domain. My system is running winbind, I've added the winbind calls to nsswitch.conf. I can get my wbinfo -u and wbinfo -g commands to show me what I want. That all seems happy. I have a

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

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
