Question

In my rspec testing. I got NoMethodError:
undefined method `password_digest=’.

But in rails console. I do can use .password_digest method.

I am so confused. I searched google. Got sever threads about this. even in stackoverflow. But those don’t help. I do have password_digest as a field in my database.

I can even set my password_digest

see:

1.9.2-p290 :005 > user.password_digest
 => "$2a$10$X8CSsstOqZKKA6qVHpW9.uH5Lzd7dxfGNCAxvIbePpcfBg8KFbD4y" 
1.9.2-p290 :006 > user.password_digest = 1
 => 1 
1.9.2-p290 :007 > user.password_digest
 => 1 

And also, in my app. everything seems fine. That’s weird.
Please help…

And this is my user_spec.rb code:

  validates :name, presence: true, :length => { maximum: 50 }
  valid_email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
  validates :email, :presence   => true,

  validates :password,  length: { minimum: 6}
end

Answer 1

class User has method password_diges but has no method password_digest=
this is not the same methods, so instance of User shall not be responsible on password_digest
it shoud return password_digest but should_not respond_to password_digest i think
