試圖獲得認證的紅寶石在工作軌道

Question

我已經試過以下ROR代碼：

class SessionsController < ApplicationController 
    def new 
    end 

    def create 
    user = User.authenticated(params[:email], params[:password) 
    if user 
     session[:user_id] = user_id 
     flash[:notice] = "Log In Complete" 
     redirect_to root_url 
    else 
     flash.now.alert = "Invalid Email or Password" 
     render 'create' 
    end 
    end 

    def destroy 
    session[:user_id] = nil 
    redirect-to root_url, :notice =>"Logged Out" 
    end 
end 

但我得到這個錯誤：

I:/dev/abierto/app/controllers/sessions_controller.rb:5: syntax error, unexpected ')', expecting ']'
I:/dev/abierto/app/controllers/sessions_controller.rb:19: syntax error, unexpected tIDENTIFIER, expecting keyword_do or '{' or '(' redirect-to root_url, :notice =>"Logged Out"
I:/dev/abierto/app/controllers/sessions_controller.rb:19: syntax error, unexpected tASSOC, expecting tCOLON2 or '[' or '.' redirect-to root_url, :notice =>"Logged Out"
I:/dev/abierto/app/controllers/sessions_controller.rb:22: syntax error, unexpected keyword_end, expecting $end

任何人可以幫助我，告訴我什麼，我我做錯了嗎？

Answer 1

起初：

user = User.authenticated(params[:email], params[:password**]**) 

...但可能會有更多的錯誤。粘貼行號

Answer 2

你缺少]第5行，它應該閱讀：

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

也redirect-to是錯誤的，它應該是redirect_to

我不是在flash.now.alert甚至不確定，也許應該是flash.now[:alert]
