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

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

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

Hello, I''m having a hard time explaining this, so I hope i can say this correctly. I have these tables: people id fname lname departments id name buildings id name room wtkeys id key_number key_way Issued_keys id people_id department_id building_id wtkey_id date_issued My

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, Windows XP Oracle 10g client OCI8 0.1.16 Ruby 1.8.5 Rails 1.1.6 I''m hitting weird behavior with the Oracle adapter and a find_by_sql call on a multi-table join. The SQL looks like this: SELECT DISTINCT e1.ip_address, loc.street, loc.city, loc.state FROM schema.net_element ne, schema.equipment e1, schema.equipment e2, schema.building b, schema.cust_loc cl, schema.location

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,

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, 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

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

I have created a scaffold Admin/Radicals for doing CRUD. However, I''m not sure exactly where the scaffold uses the save() method. For a new entry, it creates form "radical" referencing method create(). The code for create() is as follows: def create @radical = Radical.new(params[:radical]) if @radical.save flash[:notice] = ''Radical was

Hi guys, I was thinking aboiut this for a while: If I have nested resource routes, for example /building/1/floor/2/ room/ 3 (building has_many floors and so on), I have to call the room_path method like this: room_path @room.floor.building, @room.floor, @room Isn´t there a better way to handle nested routes with foreign keys, or can I have this method overwritten somewhere?

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

Hello, - the form posted by the user have a date field - this date is begin_date, I need to compute end_date - so, added callback before_validation_on_create - in this method I do : end_date = begin_date >> 12 - unfortunately, beeing in before_validation the actual self.begin_date have not been type casted - It''s always a string - unfortunately again, I can''t put this code

Hi, I needed to be able to add actions to be taken during the lifecycle of ActiveRecord object, but needed to configure it dynamically. Observers were not flexible enough and I ended up developing ArEvents, which lets you easily attach and detach event listeners, the events correspond to the active record callbacks. If you have an existing model, just include the ArEvents module:

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

Hey, I got a form which looks like this: - form_for(@article, :html => {:multipart => true}, :url => articles_path) do |f| = errors_for(@article) .field = f.label :text %br = f.text_field :text .field = f.label :author_id %br = f.text_field :author_id .actions = f.submit But since I don''t want anyone to type in an author id I changed it

Hi all I tried and tried and tried, but I still fail in creating a form with proper validation and stuff for foreign keys... So I''d really like to get some help here. I''m creating a booking site for DJ''s, and for every booking one can choose one of different countries: class Booking < ActiveRecord::Base validates_presence_of :country_id
