    text
    copied!<p>I have a rails model with a hashed password field in it (surprise, surprise), which after some manipulation, is 40 characters long. I generate a user in script/console and it appears as follows:</p> <pre><code>#&lt;User id: 1, firstname: "true", lastname: "false", username: "chaines51", hashed_password: "2Gr0GWvPunB3x5jomRTSTZJRIelC2RW103d7f3db"&gt; </code></pre> <p>I then run user_instance.save, which returns true, and the user then looks like this:</p> <pre><code>#&lt;User id: 1, firstname: "true", lastname: "false", username: "chaines51", hashed_password: "103d7f3db"&gt; </code></pre> <p>Any idea what is happening to the other 30+ characters? I changed the field in the migration from string to text, but it still gets truncated</p> <p>EDIT: The model code is:</p> <pre><code>require 'digest/sha1' class User &lt; ActiveRecord::Base validates_presence_of :username, :password, :password_confirmation, :firstname, :lastname validates_length_of :username, :within =&gt; 3..40 validates_length_of :password, :within =&gt; 5..40 validates_uniqueness_of :username validates_confirmation_of :password belongs_to :school attr_protected :id, :salt attr_accessor :password, :password_confirmation def self.random_string(len) #generate a random salt consisting of digits and letters. chars = ("a".."z").to_a + ("A".."Z").to_a + ("0".."9").to_a salt = "" 1.upto(len) { |i| salt &lt;&lt; chars[rand(chars.size-1)] } return salt end def password=(pass) @password=pass @salt = User.random_string(40-pass.length) self.hashed_password = User.encrypt(@password, @salt) end def self.encrypt(pass, salt) hash = Digest::SHA1.hexdigest(pass+salt) hash.slice!(0..(40-pass.length-1)) hash = salt+hash; end def self.checkhash(pass, hash) salt = hash.slice!(0..40-pass.length-1) rehash = User.encrypt(pass, salt) return rehash == (salt+hash) end def self.authenticate(login, pass) u = User.find_by_username(login) return nil if u.nil? return u if User.checkhash(pass, u.hashed_password) nil end end </code></pre> <p>and the db/schema.rb is:</p> <pre><code>ActiveRecord::Schema.define(:version =&gt; 20100127034504) do create_table "categories", :force =&gt; true do |t| t.string "title" end create_table "questions", :force =&gt; true do |t| t.string "question" t.string "a" t.string "b" t.string "c" t.string "d" t.string "e" t.datetime "created_at" t.datetime "updated_at" end create_table "questions_quizzes", :id =&gt; false, :force =&gt; true do |t| t.integer "app_id" t.integer "category_id" t.datetime "created_at" t.datetime "updated_at" end create_table "quizzes", :force =&gt; true do |t| t.string "title" t.integer "category_id" end create_table "schools", :force =&gt; true do |t| t.string "name" t.integer "coach_id" end create_table "users", :force =&gt; true do |t| t.string "firstname", :null =&gt; false t.string "lastname", :null =&gt; false t.string "username", :null =&gt; false t.boolean "needs_pass", :default =&gt; false t.integer "school_id" t.datetime "created_at" t.datetime "updated_at" t.boolean "confirmed", :default =&gt; false t.text "hashed_password" end end </code></pre>
