通过用户名或电子邮件设计查找

Question

after setup devise i would like to get the user by username or email with in a api session

I passed login to parameters but rails spits out a error

User.find_for_database_authentication(:login => params[:username][:email])

the overwrite of find_for_database_authentication on model is already done.

def self.find_for_database_authentication(warden_conditions)

Someone has any hint to spare?

Devise

class Api::SessionsController < Devise::SessionsController

  respond_to :json

  def create
    resource = User.find_for_database_authentication(:login => params[:username][:email])



    if resource.valid_password?(params[:login][:password])
      sign_in(:user, resource)

      render :json=> {:auth_token=>resource.authentication_token, :email=>resource.email}, :status => :ok
      return
    end
    invalid_login_attempt
  end
end

Answer 1

I did this by overriding find_for_database_authentication like this:

class User
  def self.find_for_database_authentication(auth_hash)
    self.where("username = :query OR email = :query", query: auth_hash[:email]).first
  end
end

Nothing more was needed.

Answer 2

试试这个： User.find_by(username: 'username')或User.find_by(email: 'your@email.com')
