小编Med*_*ros的帖子

我今天开始使用 Python Anywhere.我按照说明创建了数据库MySQL.问题是我无法做一个简单的manage.py syncdb,因为我的mysql数据库中的用户'irgmedeiros'出现访问被拒绝错误.我无法授予用户权限,也无法创建具有权限的其他用户.怎么解决？无法在他们的论坛中找到解决方案,我正在等待电子邮件的回答.以前有人经历过这个吗？

是否有命令允许结账最后一个分支？喜欢:

git checkout --recent

要么

git checkout --previous

这个想法是当你经常切换分支时,很容易忘记你在当前分支之前工作的分支.此外,如果有办法为此设置别名,那将是valide.

我正在尝试下载其中一个流浪汉的盒子,但此时他们的服务器速度很慢.他们有公共镜子吗？我想下载precise64.box文件.

谢谢

我对django守护者有些问题.我有一个新闻模型定义

class News(models.Model):
    title = models.CharField(_('Title'), max_length=255)
    slug = models.SlugField(_('Slug'), unique_for_date='pub_date',)

    objects = models.Manager()
    featured = FeaturedNewsManager()

    link = models.URLField(_('Link'), blank=True, null=True,)

    class Meta:
        permissions = (('view_news', _('view news')))

然后我尝试将view_news权限分配给我的一个用户,我收到以下错误:

>>> from guardian.shortcuts import assign_perm
>>> g = Group.objects.latest('pk')
>>> n = News.objects.get(pk=4)
>>> assign_perm( 'news.view_news', g, n)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/home/roberto/.virtualenvs/ve_news/local/lib/python2.7/site-packages/guardian/shortcuts.py", line 93, in assign_perm
    return model.objects.assign_perm(perm, group, obj)
  File "/home/roberto/.virtualenvs/ve_news/local/lib/python2.7/site-packages/guardian/managers.py", line 90, in assign_perm
    permission = Permission.objects.get(content_type=ctype, codename=perm)
  File …

我想从这个URL解析JSON(http://api.flickr.com/services/feeds/photos_public.gne?format=json),但该文档实际上返回了一个无效的JSON.看到

       jsonFlickrFeed({
        "title": "Uploads from everyone",
        "link": "http://www.flickr.com/photos/",
        "description": "",
        "modified": "2012-11-26T18:27:41Z",
        "generator": "http://www.flickr.com/",
        "items": [
       {
            "title": "2012 Thanksgiving Holiday Weekend",
            "link": "http://www.flickr.com/photos/agape_boarding_school/8220697785/",
            "media": {"m":"http://farm9.staticflickr.com/8478/8220697785_bb298ac5b3_m.jpg"},

       },  ...

我想让我的解析器尽可能通用,那么更好的方法是删除"jsonFlickrFeed"(文档的一部分,只用它自己的JSON？
