Error using logout link with Devise Rails 4

Question

I'd like to start off saying I know there are other questions on here about this however none of them are using rails 4 and I could not get their suggestions to work. The error I am getting is "uninitialized constant HomeController"

code in index.html.erb

<%if user_signed_in? %>
    <p align= "right">Hello <%=current_user.email %> <%= link_to "sign out", destroy_user_session_path, :method => :delete %></p>

Here are the first 3 lines to application.html.erb

<!DOCTYPE html>
<html>
<%= javascript_include_tag :defaults %>

I'm thinking it might have something to do with this line in my routes.rb file

root 'home#index'

Thanks in advance

Answer 1

you dont have home controller at app/controllers/

you should create app/controllers/home_controller.rb with:

class HomeController < ApplicationController
  def index
  end
end

for your second error: you call method email for nil(not post).

Answer 2

问题出在我的routes.rb文件中，它应该读为“ posts＃index”而不是“ home＃index”
