Instance Method Details
#has_secure_password ⇒ Object
Adds methods to set and authenticate against a BCrypt password. This mechanism requires you to have a password_digest attribute.
Validations for presence of password, confirmation of password (using a “password_confirmation” attribute) are automatically added. You can add more validations by hand if need be.
You need to add bcrypt-ruby (~> 3.0.0) to Gemfile to use has_secure_password:
gem 'bcrypt-ruby', '~> 3.0.0'
Example using Active Record (which automatically includes ActiveModel::SecurePassword):
# Schema: User(name:string, password_digest:string)
class User < ActiveRecord::Base
has_secure_password
end
user = User.new(:name => "david", :password => "", :password_confirmation => "nomatch")
user.save # => false, password required
user.password = "mUc3m00RsqyRe"
user.save # => false, confirmation doesn't match
user.password_confirmation = "mUc3m00RsqyRe"
user.save # => true
user.authenticate("notright") # => false
user.authenticate("mUc3m00RsqyRe") # => user
User.find_by_name("david").try(:authenticate, "notright") # => nil
User.find_by_name("david").try(:authenticate, "mUc3m00RsqyRe") # => user
