设计 - Rails 4 - 无法登录

Question

I just started using Rails 4. I got devise<\/code> setup with custom fields. I'm able to login after I register, but I'm not able to login from the login page. The user registration goes in fine, and I have username<\/code> , password<\/code> etc in the database table.

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :confirmable,
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable

  validates :username, :uniqueness => true, :presence => {:message => '- Username cannot be blank'}
  validates :first_name, :presence => { :message => " - Firstname cannot be blank!"}    

  private
    def user_params
        params.require().permit(:first_name, :last_name, :username, :email, :password, :password_confirmation)
    end
end

Answer 1

In your application controller you have permitted params for sign_up, but not for sign_in. So i you change the configure_permitted_parameters method to this, it should work:

def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:username, :password, :remember_me) }
    devise_parameter_sanitizer.for(:sign_up) {|u| u.permit(:username, :first_name, :last_name, :password, :password_confirmation, :email) }
  end

Answer 2

I was using devise confirmable. devise.rb was setup in such a way that it wouldn't let me log in if the account's email wasn't confirmed. So what worked in my case was adding the following flag in devise.rb config.allow_unconfirmed_access_for = 999.days
