Today I found these comments in active record''s callbacks.rb file: # If the returning value of a before_validation callback can be evaluated to false, the process will be aborted and Base#save will return false. # If Base#save! is called it will raise a RecordNotSave error. # Nothing will be appended to the errors object. This caused me a lot of frustration earlier when I was

Hi all My visitors can create party organisator profiles, and I want assign them as the creators (the field creator_id in the organisators table references a member in the members table). To do that I tried it with before_validation: def before_validation creator = Member.find 1 end Sadly, this does not work. The validation validates_presence_of :creator_id Still tells me, that

Hi, I was looking around a bit and couldn''t find any callbacks that executed before before_validation The current problem with using before_validation is that it won''t fire if I''m not using validations with #save(:validate => false) - which makes sense. Before_save won''t suffice because I want these callbacks to fire before validation on the occasions that

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 trying to validate a numeric value passed in from a form, which is saved in a MySQL db as decimal(9,2) Now problem is I need to ensure people don''t enter a form value like -. 003. In my validations, I have a validates_numericality_of check being done. Furthermore, in validate method, I have a check using an if statement such as : ((an_object[n].nil? or an_object[n] < 0) and

I am still trying to get sentry working to encrypt a couple of attributes in the model. One of them is a password field and the other ssn#. I have crypted_password and crypted_ssn in the db. In addition, I also have validates_uniqueness_of :ssn Here is the problem... I get the error MysqlError: Unknown column ''ssn'' in ''where clause'': SELECT * FROM students

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`,

Hi all, For various reasons I need to have foreign keys with not null constraints. Eg: create_table :people do |t| t.column :name, :string t.column :household_id, :integer, :null => false end create_table :households do |t| t.column :name, :string end add_foreign_key_constraint :people, :household_id, :households, :id So the people table has a foreign key into

Hi all, I''ve got a form which accepts a "price" field and I''m attempting to validate it and allow some flexibility in the way the user enters it. It''s a numeric field but I want the user to be able to enter dollar signs and commas naturally in the data entry. I''m trying to understand how to use validates_format_of, and I''m not sure what

Hi, I often find myself using bits of code like this inside ActiveRecord, perhaps it''s useful for others, or others can improve on it: ########### # fix user input before validating it before_validation :sanitize_input # santize input before actual validation is called # this uses the little methods defined below def sanitize_input trim %w(adres postcode woonplaats email naam

I tend to allow nulls in cases where the value is unknown, even if it''s a text/varchar field. RoR seems to push empty strings into these fields. Is there any way to get RoR to use NULL vice '''' if the input box is empty? Thanks! - Ian

Buildings have units. Units have rooms. Rooms have people. I can grab building, room, and people IDs and store them in a session[:variable]. However, when creating a new unit, I need to give that session[:building_id] to ActiveRecord for creation. I''m not sure whether to use hidden fields or do it all in the model ''before_validation'' - in either case I

I want to remove the leading and training spaces for most of the resources in my rails application For a new POST request, rails does the xml parsing and passes the params hash to the controller. Some of the parameters have leading and/or trailing whitespaces which are causing problems (e.g. new resources being created rather than using the old ones). I don''t want to put the code in all

who can explain this to me? def before_validation logger.info url url = "http://" << url if url[0..3]=="www." end the logger line correctly logs any URL that''s been submitted, let''s say it''s "www.amazon.co.uk" BUT Rails raises an exception on the next line, complaining about nil. [] (obviously from the url[0..3] bit) It works

Hi All, Is there a way to filter / modify the output of a model class before it''s returned to controller/view that''s calling it? Example: I have a field phone_number which I always want to preformat using the number_to_phone() helper.... Any help is appriciated. Thanks! -- Posted via http://www.ruby-forum.com/.

I''m trying to create a separate class to do validation so that about 10 models can use the same date validation. I have tried to use the example from the agile book but it''s not working. Here''s what I have: app/models/date_callbacks.rb class DateCallbacks def before_validation(model) if model.start_date > Date.today model.errors.add(:start_date, "must

If I have a module with a callback in it: module Sanitize module PhoneNumber def before_validation self.phone.gsub!(/\D/, '''') if attribute_present?(''phone'') end end module MobileNumber def before_validation self.mobile.gsub!(/\D/, '''') if attribute_present?(''mobile'') end end end

Hi everyone, I''m starting on my first rails project and I have a problem that I''m sure has a simple solution. I have two models, an address model and a state model. The address belongs_to :state, foreign_key=>"state" and validate_associated :state I have new & edit controllers for address which contain a drop down list for the state choice. My list was

before_save :strip_strings validates_uniqueness_of :username validates_presence_of :username private def strip_strings self.username = username.gsub!(" ","") end example: username = " gissmoh-/upiLifMog2ELgA04lAiVw@public.gmane.org " becomes gissmoh-/upiLifMog2ELgA04lAiVw@public.gmane.org and is stored in the

Hi, I''ve defined the following model: class Eintrag < ActiveRecord::Base before_validation :vali protected def vali # self.feld1.reverse! self.feld2 = self.feld1 end end Now I''m wondering why I have to write self.feld2=self.feld1 and why @feld2=@feld1 doesn''t work. I''ve found the thread
