similar to: Blank fields getting validated

Dear all, I am trying to understand the following behaviour of the ActionMailer in Rails 2. I have an emailer_controller.rb class EmailerController < ApplicationController def send_mail Emailer::deliver_contact_email(params[:email]) end end I have a model emailer.rb class Emailer < ActionMailer::Base def contact_email(email_params, sent_at = Time.now) @recipients =

Hello, I''m trying to cut down the errors if the guy already getting the empty nickname, so he doesn''t get anything about the nickname is short. validates_presence_of :nickname This below is not working ? validates_length_of :nickname, :within => 4..40, :if => Proc.new { |user| user.nickname.length > 1 } nor this one below? validates_length_of :nickname, :within

Hi! Yesterday I started to write my unit tests for the fist time using rails. I''m using this method: http://blog.codahale.com/2005/12/23/a-rails-howto-simplify-your-unit-tests/ My customer_test.rb looks like this: require File.dirname(__FILE__) + ''/../test_helper'' class CustomerTest < Test::Unit::TestCase fixtures :customers # Replace this with your real

In the model I have: validates :square_meters_public_land, :barrier_meters, :numericality => { :greater_than_or_equal_to => 0 }, :allow_nil => true but if, in the field, on create, I don''t insert a value I have the error "field is not a number". -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Here''s the issue: When I submit a form for updating, @person.update_attributes doesn''t work. But the next nested clause for updating images DOES work. How is that possible? However no matter what I do the Person object will not change its attributes. def edit @person = Person.find(params[:id]) if request.post? @person.update_attributes(params[:person])

I think I must be doing something wrong... when a form returns params to the controller, empty fields appear to be returned as blank, not nil. so what''s the point of an :allow_nil=>true setting on a validation? it fails because blank is not the same as nil. i would expect either returned empty fields to be nil, or :allow_nil to really be :allow_blank. otherwise i have to do a search

Hello people, I''d like to detect whether an attribute of a model has vaildates_presence_of applied to it so I can automatically apply a mandatory (*) to the field...it doesn''t look easy...any ideas? Cheers, -- Dan Webb http://www.danwebb.net

Hello all. I''ve got the following in my model: class Individual < ActiveRecord::Base validates_presence_of :first_name, :last_name, :street, :city, :state, :zip validates_acceptance_of :AZ_resident, :message => "You must be an Arizona resident." end The AZ_resident field is present and defined as boolean (PostgreSQL 8.1), but validation will not occur.

Sorry if I''m just dumbing out, but is there a reason that when using Single Table Inheritance Rails doesn''t really validate the "type" field or provide some mechanism to do so? seems like a good way to corrupt a database. Because the "type" is also a special attribute, I had to resort to an ugly hack like: class ActiveRecord::Base def type_attr

Is trhere any way how to support allow empty? Rails prefer empty string than null for database and then validations with allow_nil fails. -- Posted via http://www.ruby-forum.com/.

Is there a way to use validates_numericality_of and still allow null values? I have a model with some optional values that can be nil, but if they''re present, they must be numbers. Will I need to construct a custom valiation for this, or is there some method built in? Seems like it would be a common enough need. Jeff -- Posted via http://www.ruby-forum.com/.

How would I use validations to ensure I either received a blank value or a ten digit number? If I set validates_length_of :field, :in => 0..10 then that would allow any value in-between. The allow_nil => true option does not seem to work. I''ve also tried using this with some combination of validates_numericality_of but cannot get it to work. Any help would be greatly

Hello guys, I''m trying to validate the input of an integer from a form, here is a bit of code: This is the definition of the offending column in the migration: t.column :position, :integer, :default => 0, :limit => 3, :null => false And here is how I try to validate it inside de model: validates_length_of :position, :within => 1..3 And this is the exception I get when I

i have a model with this: file_column :image validates_file_format_of :image, :in => ["gif", "png", "jpg"] If inthe form the user not insert the image i receive an error. If i remove: validates_file_format_of :image, :in => ["gif", "png", "jpg"] it works. Is possible do the validation only when user insert the image in form? i

It appears that if your trying to use validates_inclusion_of for a string value allow_nil wont work. For example, if I have an attribute :year which is stored as a varchar then: validates_inclusion_of :year, :in => "1980"..Time.now.year.to_s, allow_nil=>true will successfully validate the range but will not allow an empty input field to be submitted. However, if :year is

I''ve been working with the problem that Joe Hosteny has been talking about on this list and on the tickets he''s posted (http://dev.rubyonrails.com/ticket/1196) and have come up with a tentative solution that I''d like to bring up here. What if we use a "conditional" parameter in the validates_* methods? Here''s how it would look like in practice:

Hi All, I’ve got a few versions or Rails installed and I''d like to run an App I’m developing with various versions of Rails. I heard of two ways to switch the version of Rails that an app uses: 1. Use GitHub as described by http://kylecordes.com/2008/04/30/git-windows-go/ . But that requires using Bash in a Command Window and more steps than I want to go through. 2. Alter

Hi, I''m looking for a way to implement subforms. For example, a form where you can add clients, and at the same time enter contactpersons for this client. I''ve been looking around, reading ebooks, etc, but can''t seem to find a good example/tutorial for something like this. So I would be very thankful if someone could point me in the right direction. Thanks, Sven

Dear Rubyists/Rails gurus, Though I''ve successfully completed the various Rails tutorials online and the Depot application from the Agile Web Development with Rails book, I''m still pretty much a Ruby/Rails newbie. I''m trying to learn by writing my own simple blogging application, but I''ve run into a problem that has had me scratching my head for a few days now.
