validates_uniqueness_of :username not catching case sensativity - ruby-on-rails-3

I just discovered that even with a validates_uniqueness_of :email, :username customers can create new accounts with different case similar values.
Examples:
username
USERNAME
email#email.com
EMAIL#EMAIL.COM
Is this by design or am I missing something?
I have this validate line in my model
validates_uniqueness_of :email, :username
It does work as expected with similar values:
username
username
I'm using rails 3.2.9

Yes this is by design. email#email.com and EMAIL#EMAIL.COM are not the same string, what you want in your situation is to turn case sensitivity off.
validates_uniqueness_of :email, :case_sensitive => false
validates_uniqueness_of :username, :case_sensitive => false

How to check emptiness on devise custom fields?

I've added two news fields to my users table :first_name and :last_name
In migration file I've specified these fields couldn't be null using the following code:
class Userscustomfields < ActiveRecord::Migration
def change
add_column :users, :first_name, :string, {:null => false, :limit => "128"}
add_column :users, :last_name, :string, {:null => false, :limit => "128"}
end
end
I've checked on my database and the table was configurated correctly. But when I'm going to do a new register, my rails app allows to me to add a new user with first and last names empty. The app saves the fields with "", which didn't worked as I expected.
How can I do prevent this, by making a check of emptiness on my field before save them on my database?
I put on model user.rb
validates :first_name, :last_name, presence: true

Rails nil value when saving to database

I am trying to implement a user authentication system inside rails, this is my model:
class User < ActiveRecord::Base
attr_accessible :id, :email, :name, :password, :created_at, :updated_at
has_secure_password
before_save { email.downcase! }
validates :email, presence: true, :uniqueness => { :case_senstive => false }
validates :name, presence: true
validates :password, presence: true, length: { minimum: 6 }
end
Running in the console i can read the User table successfully, then when i try to create a record:
User.new(:name => "A", :email => "a#a.a", :password => "password")
running valid on it retrurns true, but when saving the record, i get error:
users.password may not be NULL
Extracting the password out of the hash works fine.
What is the problem?
Thanks
Where are you setting :password_confirmation? The example in the docs suggests you need it.
http://api.rubyonrails.org/classes/ActiveModel/SecurePassword/ClassMethods.html
Main problem is in has_secure_password. If you are using that you should have string field :password_digest (it's where your encrypted password will be saved). And you need delete field :password and your validator of presence for that too. After add gem 'bcrypt-ruby', '~> 3.0.0' .
And now that should work
user = User.new(:name => "A", :email => "a#a.a",
:password => "password", :password_confirmation => "password")
But better use great gem https://github.com/plataformatec/devise . It has everything you need.
NEW ADDED
you should have attr_accessible for :password_confirmation too and that field should be used in your form.

Rails validation error email is too short, email is invalid

In attempting to seed my database I ran into a validation error on my User model's email attribute. The error:
Validation failed: Email is too short (minimum is 5 characters), Email is invalid
The thing is, my email is xxxxxxxx#gmail.com. I have five characters. Sorry for the beginner question but I don't know what is going on. I recently followed Railscasts to reset a User's password, and enable CanCan. I'm not sure if CanCan would affect anything, but prior to exploring that new functionality I've been able to fully seed my database without problems. I've pasted in some of my code below. I'm running Rails 3.0.5 and Ruby 1.9.2.
An example of how I create a User in my seed file:
me = User.create(:email => 'me#gmail.com', :password => 'test', :profile => my_profile)
User.rb model:
class User < ActiveRecord::Base
attr_accessor :password
attr_accessible :password, :password_confirmation
before_save :encrypt_new_password
before_create { generate_token(:auth_token) }
before_validation :downcase_email
has_one :profile, :dependent => :destroy
accepts_nested_attributes_for :profile
validates :email, :uniqueness => true,
:length => { :within => 5..50 },
:format => { :with => /^[^#][\w.-]+#[\w.-]+[.][a-z]{2,4}$/i }
validates :password, :confirmation => true,
:length => { :within => 4..20 },
:presence => true,
:if => :password_required?
Add :email to attr_accessible to allow mass assignment on it. Without that the email field will not even be set so validation will fail.

Mongoid and has_secure_password

I am trying to use rails 3.1 authentication using mongoid instead of active model
class User
include Mongoid::Document
include ActiveModel::SecurePassword
has_secure_password
validates_presence_of :password, :on => :create
attr_accessor :email, :password, :password_confirmation
field :email, :type => String
field :password_digest, :type => String
end
the problem is password_digest is not recognized by the bycrypt as in active model example http://railscasts.com/episodes/270-authentication-in-rails-3-1
Thanks
For anyone who is interested, the most minimal requirement for using has_secure_password with Mongoid is simply the inclusion of ActiveModel::SecurePassword in the model.
class User
include Mongoid::Document
include ActiveModel::SecurePassword
field :username
field :password_digest
has_secure_password
end
Article
Put
has_secure_password
After
field :password_digest, :type => String

Rails 3: validates :presence => true vs validates_presence_of

What is the difference between validates :presence and validates_presence_of? Looking through ActiveModel it looks like they setup the validation the same way. However, given the following model definition:
class Account < ActiveRecord::Base
has_one :owner_permission, :class_name => 'AccountPermission', :conditions => { :owner => true, :admin => true }
has_one :owner, :class_name => 'User', :through => :owner_permission, :source => :user
validate :owner, :presence => true
validates_associated :owner
end
Calling save on an instance of Account does not validate the presence of owner. Though, if I use validates_presence_of it will.
All those validates_whatever_of :attr macros do is call validates :attr, :whatever => true.
The problem is you are using validate and not validates.
In Rails 3.x and 4.x - it is now encouraged to use the following syntax:
validates :email, presence: true
validates :password, presence: true
Instead of the 2.x way:
validates_presence_of :email
validates_presence_of :password
In fact validates and validates_presence_of is not entirely equal !
validates_presence_of is allowing you to also lazily check by example of the value in the field is included in another table.
Like that:
validates_presence_of :pay_type, :inclusion => PaymentType.names
Which is something you can't do as easily with something like that
validates :pay_type, presence, :inclusion => PaymentType.names
Cause the inclusion is only evaluated the first time (not in a lazy way)
I would have thought that it is appropriate to use validates :foo presence: true when you want to include other validations of :foo such as length or uniqueness. But if you know the only validation you'll need for an attribute is presence, then validates_presence_of appears to be more efficient.
So:
validates :foo, length: {maximum: 50}, uniqueness: true,
format: {with: /bar/},
presence: true # lots of validations needed
But:
validates_presence_of :foo # only presence validation needed
