阅读更多关于 Why does current_user session become nil when updating a user?

问题 I'm using Devise and CanCan for user authentication and administrating roles restricting access to parts of my Rails 4 app for certain users. I've run into some problems with updating a user. The update works fine and the user object in the db get updated as it should, but my user session is lost on the following redirect_to my user show action. current_user becomes nil which means that CanCan restricts the access to the user show action. Why does current_user become nil after update, when

问题 I just finished my ruby foundations coursework at Bloc and I'm starting to bury my head into rails development. Things were going smooth until I hit this snag with devise and confirmation emails. I tried googling and looking around at some other questions but couldn't really find any that gave me anything that I could pull from and apply to my situation. I'm receiving the following error when signing up for an account. Net::SMTPAuthenticationError in Devise::RegistrationsController#create 535

Heroku/Rails/Devise: The change you wanted was rejected

问题 I'm having a problem with my Rails 4.2 app running the latest version of Devise on Heroku. I'm going to preface this by stating that I have not pushed any code changes to production in quite some time and that this issue only started recently. When I go to log in, I receive an error saying "The change you wanted was rejected." When I view the logs, I can see that it's a problem with the CSRF token. 2015-04-04T19:52:22.430533+00:00 app[web.1]: Started POST "/users/sign_in" for 76.119.72.58 at

Windows API 搭建OpenGL窗口

阅读更多关于 Windows API 搭建OpenGL窗口

步骤： 1、创建windows窗口，得到窗口句柄hwnd 2、获取该窗口的设备环境hDC（当然也可以获取其他的设备环境，但我们一般是在创建的窗口上绘制） 3、创建OpenGL绘制环境RC，这个只能从hDC创建 4、将hDC和RC绑定到当前的线程注：RC表示OpenGL的绘制环境，所有的OpenGL命令都会在RC这个绘制环境中作用，所以必须在RC绑定到当前线程之后才能调用OpenGL命令，否则运行出错，内存访问错误。　　一般的笔刷绘制，在hDC下即可。封装的窗口类如下：　　GLWindow.h #pragma once #include <windows.h> #include <GL/glew.h> #include <iostream> class GLContext { public : GLContext(); ~ GLContext(); void Setup(HWND,HDC); void SetupPixelFormat(HDC); private : HWND hWnd; HDC hDC; HGLRC hRC; int format; }; GLContext::GLContext() { this ->hWnd = 0 ; this ->hDC = 0 ; this ->hRC = 0 ; this ->format = 0 ; } GLContext::
