Learning Devise for Rails

Rails
1

I’m new to rails and was trying to get a handle on Devise. I’m
following the Packt Pub - Learning Devise For Rails tutorial and have a
problem around pg 19-20 (CH2). I’ve created a user, logged out, but
when I try to login again I get this error:

NameError in Devise::SessionsController#create
undefined local variable or method `signin’ for
#Class:0x00000004352b00

I was confused because I see “Sessions Controller” in the error, but the
code lists is in my devise user model:

class User < ActiveRecord::Base

Include default devise modules. Others available are:

:confirmable, :lockable, :timeoutable and :omniauthable

devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable

attr_accessor :signin

validates :username, :uniqueness => {:case_sensitive => false}

def self.find_first_by_auth_conditions(warden_conditions)
  conditions = warden_conditions.dup
  where(conditions).where(["lower(username) = :value
    OR lower(email) = :value", { :value => signin.downcase }]).first
end

end

Here’s a link to everything I have so far:

Any help that could be provided would be greatly appreciated!

If you are using Rails 4+, you need to read the Strong parameter section
of
the Devise github page here https://github.com/plataformatec/devise.

What is this attar_accessor supposed to do? Do you set it to a value at
any point? This is not a part of Devise, as far as I can tell.

I found this link very interesting:

I don’t know the dynamics of Devise, but I looked at your application:
2 controllers: application and home. home has show, new, edit defs.
All
empty
1 model user
3 view folders: devise, home, layouts.
Devise has folder session with new.html.erb. It has:
<%= form_for(resource, :as => resource_name, :url =>
session_path(resource_name)) do |f| %>

<%= f.label "Username or Email" %>
<%= f.text_field :signin, autofocus: true %>
Where have you defined resource?

Thanks for the help, everyone. After following the link to github that
Elizabeth posted I was able to cut and paste some updated code.

Thanks again.
