similar to: after_(read|find) callback?

Names of models in my application have accented characters that imply unexpected orderings. For instance ?vila should go before Madrid, but String#<=> puts it the other way aroud. I am only sorting for views, so it would be OK to do some normalization on-the-fly on Ruby land, and since the same criteria has to be used throughout the application I was thinking on some sort of

Hi everybody I would like a function as the "before_save" method in the model. But it must be the opposite. When I take out data from the database through the model, I want to call a function before the data are available in the controller. Can anyone help me? ---- >>>> thx <<<< ---- -- Posted via http://www.ruby-forum.com/.

What''s the better thing to do in a before_save if you don''t want the save to continue? raise an exception, or do an errors.add or both? Thanks, Chris Nolan.ca http://kweschun.com/ - Do you have a Kweschun?

I have a new @offer that needs to generate a document if saved. But that''s all or nothing: transaction do @offer.save! generate_document end # handle exceptions if needed If save! fails everything is fine, but if generate_document raises an exception @offer is left as a model with timestamps, id, which is not a new_record? anymore (though the database was

In the Rails Recipes book the recipe "Keeping track of who did what" explains how to do decoupled observing of models. In my application I''d like to do a similar thing but watching the controllers. For example, when somebody hits the login method of the Security controller, I''d like to make a note of it. In this case I could observe the User model and watch for

Hey guys, I''m having a hard time w/ the after_update callback on rails... As far as I can tell, when I define a after_update callback on a model, the attributes of the object have the same values that they had *before* Base.save was called. I''m probably wrong so here''s the code: UNIT TEST: def test_register_item_adjusts_account_balance account =

One of my models has a column that is updated very frequently from a separate process, so it is important that when a record is saved in rails, this column should be left alone. In the update method of the controller I have: @record = MyModel.find(params[:id]) @record.update_attributes(params[:my_model]) params[:my_model] doesn''t have a reference to the column I''m talking

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

Is there any easy way to make a fancy looking form to take phone numbers. Something that looks like this: [ ] - [ ] - [ ] ext: [ ] Then when you submit it it''s combined into one string in the database. Optimally it would auto-switch from field-to-field after you fill each field. Has anyone seen anything like this in Rails? Thanks, Adam -- Posted via

Hi, I have a user model with an e-mail field. When a user registers for the site, I want them to confirm their email address by typing it in again. If they change their email address, I want them to confirm their email address by typing it in again. However, the user might change things on their account not related to their email address, such as their phone number, and they should not have

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

I have 2 distinct types of users (artists and curators) in my system and they currently share all associations (eg has_one :portfolio). However, a curator shouldn''t have a portfolio so I would like to only add that association when required. Obviously I could just return nil for that method, but it doesn''t feel right having that there in the first place. What''s the best

Question for all: Right now i have a Table in a mySQL DB that has a row called Ingredients. When the data is entered into the DB its enter like so from a text area: 1 1/2 lbs. beef top sirloin, thinly sliced 1/3 cup white sugar 1/3 cup rice wine vinegar 2 tablespoons frozen OJ concentrate 1 teaspoon salt 1 tablespoon soy sauce 1 cup long grain rice 2 cups water 1/4 cup cornstarch 2 teaspoons

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

There''s a small inconsistency in ActiveRecord''s callback syntax that has tripped me up before. It wouldn''t be a big deal, but it can lead to a silent failure. I''d like to suggest that it either be made consistent or be made to fail loudly. The issue is that to do something before validating, but only when creating, you use `before_validation on: :create`,

Le''s say that I have a table called people and the column middle_name is nullable. If the user enters say blank or empty space then in the database it is recorded as empty space. I would like in all my models all empty spaces to be recorded as null. I guess I can write a plugin which will do so for all the models but I''m sure something like that should already be existing.I

I read in the instructions of Tracks that "upgrading via the rake migrate command is quite a bit more tricky currently with SQLite and SQLite3". Is there any gotcha regarding migrations and SQLite3? -- fxn

Nothing special, just my first plugin. it came out of a request I saw on the list from someone who wanted to be able to tell if a model''s attributes had changed prior to being saved. Well, this plugin does just that (at least I hope it does). http://rubyforge.org/projects/actsasmodified/ Please see the README for details. Constructive comments and criticisms are appreciated.

i used this private function for removing leading and trailing white spaces from the values.that below function would be called before_save. when i print the value after it strips.it prints string without any spaces.but in the table fields it saves with spaces . waht would be the problem.pls help me class CompanyInfo < ActiveRecord::Base before_save :strip_whitespace def strip_whitespace

I''m using Restful Authentication, and the code to create a user is pretty straight forward - there is a before_save action and a before_create action: before_save :encrypt_password before_create :make_activation_code But for some reason when I try to create a user programmatically in the controller like this: User.new(:email =>
