similar to: Using before_create and conflicting setter method...

In ActiveRecord''s callbacks, methods within a before_create callback are called after the validation, but before the model is created. This was an intentional design decision, but I think it was the wrong one. What do you think? When I think of before_create, I think of before_validation :foo, :on => :create, but, by default, before_create is synonymous with after_validation :foo,

Hi, I am having a small problem concernig how to access local variables in before_create. I am not sure how to really form this question but here goes: I am wondering why this works def before_create self.last_logged_in = Time.now self.created = Time.now end but this doesn''t def before_create @last_logged_in = Time.now @created = Time.now end The latter fails

Hello everyone, I''m having trouble figuring out which approach is better. I have the following tables: products, orders and line_items. Every time an Order is placed, the quantity field in the products table has to be updated for each LineItem in the Order. One option is to use DB triggers which is not as portable as using before_create in the Order model. But with before_create I cannot

I have the following models: User, Registration, Event. User has_many Registration, Event has_many Registration, and Registration belongs_to User and Registration. So far, so good. There''s a registration deadline on a Event though, a few days before the Event occurs. So, I have this: class Registration < AR def before_create errors.add_to_base("Registration deadline has

I have a unit test which fails using Rails 1.2RC2, because a method marked by the before_create filter is firing twice when my ActiveRecord is saved. Is a before_create filter supposed to cause multiple invocations? We have assumed it is called once, and only once, when the object is created, in our code (but we unit tested it to make certain). This is one of three issues I have with my unit

Hello, I'm working on using the LLVM JIT for a little project of mine, amazing work first off! I have a question about optimization passes. I initially have this function I've created, in python it looks like this: OS_end = 50OS_start = 0OS_timestep = 1birth_rate = .3population = 30.0for time in range(OS_start, OS_end, OS_timestep): births = birth_rate * population deaths = 0.1

Hi, Can anyone spot why the below doesn''t work? * I have a "created_by" column in my create table in the dB * I have a "before_create" line, which definitely gets called * I tried a few different ways to set the "created_by" attribute in the model but it doesn''t seem to work, i.e. doesn''t appear in the database

I know that usually when people say ''i think i found a bug in rails/ruby'' they''ve done something dumb. I''m wondering if this is the case here, but this does seem like a genuine rails bug to me. In my user model i have a few different before_create callbacks. In one of them, if it happens to return false (just because the last statement in it evaluated to

Hi list, first evening of playing with rails, so please forgive me if I ask something stupid. ;-) I created a User model and tried to use ActiveRecord callbacks to convert the password to sha1 just before saving it. For some reason postgresql gives me a error because the given password is null. To test even further I tried to change :login too, same error happens, :login is empty too. I am sure

Hi all, I am not sure how to handle interactions with categorical predictors in the GAM models. For example what is the different between these bellow two models. Tests are indicating that they are different but their predictions are essentially the same. Thanks a bunch, > gam.1 <- gam(mortality.under.2~ maternal_age_c+ I(maternal_age_c^2)+ + s(birth_year,by=wealth) + +

I stumble across some strange problem. I have a model with a virtual attribute file_contents that is a string. The model has validates_format_of :file_contents, :on => create, :unless => no_contents? (The method that returns file_contents.nil?) Then, I have a before_create callback, where I get my model''s title and description by parsing file_contents, and do write_attribute for

Hi, I''m having an issue with calling a function that I''ve defined in ApplicationHelper called format_time: module ApplicationHelper def format_time(time) time.strftime("%a %b %d, %I:%M%p") end end I use this function in my views to format the Time.now that I would have stored in my tables as a DATETIME. I''m able to use this function, without any

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 =>

I''m confused about how attributes work in models. For example: class Page < ActiveRecord::Base attr_accessor :body def foo id # works @id # won''t work IIRC body # won''t work @body #works end end Why doesn''t everything work the same? Joe -- Posted via http://www.ruby-forum.com/.

Hi. I get a RecordNotSaved exception when trying to create a user record. The error: User Columns (0.005930) SHOW FIELDS FROM users SQL (0.000465) BEGIN SQL (0.000466) COMMIT ActiveRecord::RecordNotSaved (ActiveRecord::RecordNotSaved): ... As you can see, there''s no INSERT SQL generated, which is the root cause of the problem. In my user model, I have the following

Hi, I''m calling a helper I''ve written - format_time() that is called from my views with a given time that was selected from my database and was returned to the view via an instance variable. When I call format_time from a partial, I see that I get some kind of String error and the partial won''t render. Basically, the object being passed in to format_time is already a

Hey all, I created a seed task: def books! books = Book.where(:type_id => Type.find_by_name(''Fiction'')).order(''id'') books.each do |book| @books = 4.times.map do |i| subbook! "#{book.book_num}-#{i}".to_s, :book_state => BookState[:available].id, :book => book end end puts "log it:

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`,
