Ruby-on-rails – How to verify a user’s password in Devise

deviseruby-on-rails

I'm having a problem matching user password using devise gem in rails. User password stored on my db which is encrypted_password and i am trying to find user by password, but I don't understand how to match password from form and encrypted_password in my db.

User.find_by_email_and_password(params[:user][:email], params[:user][:password])

I think this is a better, and more elegant way of doing it:

user = User.find_by_email(params[:user][:email])
user.valid_password?(params[:user][:password])

The other method where you generate the digest from the user instance was giving me protected method errors.

Ruby-on-rails – Devise form within a different controller

As Andres says, the form calls helpers which are specified by Devise and so aren't present when you access a Devise form from a non-Devise controller.

To get around this, you need to add the following methods to the helper class of the controller you wish to display the form under. Alternatively, you can just add them to your application helper to make them available anywhere.

  def resource_name
    :user
  end

  def resource
    @resource ||= User.new
  end

  def devise_mapping
    @devise_mapping ||= Devise.mappings[:user]
  end

Ruby-on-rails – Create a devise user from Ruby console

You can add false to the save method to skip the validations if you want.

User.new({:email => "guy@gmail.com", :roles => ["admin"], :password => "111111", :password_confirmation => "111111" }).save(false)

Otherwise I'd do this

User.create!({:email => "guy@gmail.com", :roles => ["admin"], :password => "111111", :password_confirmation => "111111" })

If you have confirmable module enabled for devise, make sure you are setting the confirmed_at value to something like Time.now while creating.
