similar to: after_update attributes problem

With after triggers in Postgres, there are special NEW and OLD vars accessible to trigger functions. Any such thing in Rails? Or would it entail doing something like setting a class var in before_update? Jack -- Posted via http://www.ruby-forum.com/.

Hi, I am trying to replace my old database trigger with ActiveRecord callbacks in rails. I have a model like following: class Action < ActiveRecord::Base belongs_to :inquiry def after_update #clean up all action associated with the inquiry. Action.update_all("latest = ''''", ["inquiry_id = ?", self.inquiry_id]) #find the latest action

Hi, I''m doing a <model_name>.update(....) but I''m noticing that my before_update callback is not being called. If I do a find and then a save!, I notice that it is called. The problem with a find and save in my case is that I''m not able to set all my attributes in one shot by saving params["user"] and since I can''t do this, my overloaded

I have this situation where in an after_update, I would like to know the previous value of the record instead of simply being notified the record has been updated. For example let''s say I had a table called ''foo'' which had a field ''new_flag''. I want to know when the ''new_flag'' field changes from 0 -- > 1 in an after_update so I

I''ve got a strange behaviour that didn''t seem to be happening before I upgraded to 1.2. I''ve got two models - questions and results. When a user answers a question, his answer is recorded in results. In my results model, I have an after_create that increments! a count in the question model. This increment is now triggering an after_update method I have in a

Hi, I''m using Rails/AAF with Ferret 0.10.11, and my index occasionally (every few weeks, roughly) becomes corrupted. If the index is busted, until I rebuild it our users are unable to save anything. I get errors like the one below, and the save rolls back. My question is, is there any way to catch the error, and continue with the save even if the model isn''t indexed? What

Hello. LoginSystem is cool, it populates the @session instance variable of controllers with many useful info. The fact is : it would be cool to let models know about the session, too. For instance, after_update and after_create callbacks could store *who* did *what* on *what. Aim : having ActiveRecord::Base::session defined, returning the @session of the controller which manipulates the

Hi! I got a class named EinsatzFilter which I serialized to session. Before saving to session it works afterwards I keep getting the message: "undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from ActiveRecord::Base inherited class. Code: class EinsatzFilter include ApplicationHelper attr_reader :personen, :monat, :projekte, :kunde

How to update attribute(s) and save a record instance without triggering the hooks: after_save, after_create, after_update? I know it''s possible with Record.update() but this is dynamic. Only receive the instance, without knowing its class (thus cannot call the class method update()). Or is there a way of knowing the class and calling the class method? Thank you. -- Posted via

We're using the built-in CUPS interface for printing from Samba and this, as shipped, leaves the spool files in the directory defined by [printers] path = whatever in smb.conf. Other printing types typically explicitely delete these files as part of the print command but the CUPS interface doesn't offer any facility to do this. A possible solution is, as in the attached patch, to delete

Hey guys, I''ve been playing w/ ruby for a few years now, and I finally have a project that gives me an excuse to try out rails. I''ve been liking it a lot, but it''s hard for me to grasp some of the concepts... specifically, when do I need to make a new controller? I understand that different tables need their own controller, but what about other things that are

Here is some IR that is working and executing as expected -- All allocas are in the first basic block, and only updates happen in other basic blocks. define i32 @f() { entry: %x = alloca i32 store i32 333, i32* %x %i = alloca i32 store i32 11, i32* %i br i1 true, label %if.then, label %if.else if.then: ; preds = %entry store i32 3, i32* %i

Hi Is there any way to temporarily stop the updated_at field from being updated when a record is modified with ActiveRecord? I have a date field which is keeping track of when the record data was last checked by my application and my app manually updates it, of course when I do this the updated_at field is also touched making it fairly useless for finding out when the actual data was changed

I am pondering the possibility of encrypting/decrypting some fields in a SQLite backend on-the-fly. The point of the message is not security, I know that''s broken, but whether there''s a technique that provides on-the-fly save/read filters. Of course the solution would need to work transparently in joins, so user.posts.last.title would do the right thing if title

Don''t know why, but cant seem to get this to work for me. I have a phone number field for an addressbook. In the addressbook model I have a before_update declaration that says the following: I''d like to be able to remove all special characters (just numbers please), but this doesn''t want to work for me. before_update :format_phone def format_phone self.phone =

Hi all, here is the challenge: I have this validation method, that basically prevents an object which billed = true to be updated: def before_update if read_attribute(:billed) errors.add_to_base(''This service has already been billed for'') end !read_attribute(:billed) end The above code does not work in case I do something like: object =

It's not great IR, but it doesn't look like it should actually crash, just (without SROA) produce comparatively bad code. The alloca is only referenced in the basic block that it exists. If this isn't expected to work, then we should probably improve the documentation of alloca in the language reference. David > On 5 Apr 2015, at 04:55, Eric Christopher <echristo at
