模板语法错误：“settings_tags”不是有效的标签库

Question

当我尝试运行此测试用例时，出现此错误： WHICH IS write in test.py of my django application:

def test_accounts_register( self ):
    self.url = 'http://royalflag.com.pk/accounts/register/'
    self.c = Client()
    self.values = {
        'email': '[email protected]',
        'first_name': 'bilal',
        'last_name': 'bash',
        'password1': 'bilal',
        'password2': 'bilal',
    }
    self.response = self.c.post( self.url, self.values )

my django version is 1.2.1 and python 2.6 and satchmo version is 0.9.2-pre hg-unknown

完整错误日志是：

Answer 1

在我看来，您的模板中可能有类似 {% load settings_tags %} 的代码。 Django 在已安装应用程序的目录中查找 templatetags/settings_tags.py 文件。这是没有找到这样的文件的结果。也许包含它的应用程序不在您的 INSTALLED_APPS 中，或者可能是一个拼写错误。当您将此网址输入浏览器时，您应该会收到相同的错误。

Answer 2

有时，当您忘记将 __ init __.py 放入包中时，就会发生这种情况。

Answer 3

就像@AJJ所说，您可能需要重新启动服务器才能加载新标签

Answer 4

这是此软件包的常见问题。当你从pypi获取它时，它不包含模板标签：settings_tag.py，这将导致错误'settings_tags'不是有效的标签库：找不到模板库settings_tags。

当前的解决方案是从 github zip 安装它。
