假设我有这个 Exception Message

catch (Cartalyst\Sentry\Users\LoginRequiredException $e)
{
     echo 'Login field is required.';
}

如何通过此消息 登录字段是否需要使用withErrors()？

return Redirect::to('admin/users/create')->withInput()->withErrors();

假设我有三个表用户,users_groups和groups.如何通过users_groups表获取用户的组？

class User extends Eloquent {
    protected $table = 'users';
}

class Groups extends Eloquent {
    protected $table = 'groups';
}

class Usergroups extends Eloquent {
    protected $table = 'users_groups';
}

我正计划创建一个太空射击游戏，我希望背景中的星星不断向下移动。您可以在下面查看我的代码。图片http://tinypic.com/r/9a8tj4/5

import pygame
import sys
import pygame.sprite as sprite

theClock = pygame.time.Clock()

background = pygame.image.load('background.gif')

background_size = background.get_size()
background_rect = background.get_rect()
screen = pygame.display.set_mode(background_size)
x = 0
y = 0
w,h = background_size
running = True

while running:
    screen.blit(background,background_rect)
    pygame.display.update()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    if(y > h):
        y = 0
    else:
        y += 5
    screen.blit(background,(x,y))
    pygame.display.flip()
    pygame.display.update()
    theClock.tick(10)
