NameError：名称'base'未定义（干草堆搜索）

Question

我想在我的 django 应用程序中包含全文搜索。我为此使用 whoosh-haystack。当我在安装的应用程序中包含 whoosh 和 haystack 并执行命令 ./manage.py 时，我收到导入错误。谁能解决这个问题。

settings.py
INSTALLED_APPS = {
   'django.contrib.admin',
   'django.contrib.auth',
   'django.contrib.contenttypes',
   'django.contrib.sessions',
   'django.contrib.messages',
   'django.contrib.staticfiles',
   'search',
   'whoosh',
   'haystack',
 }

当我在我的模型中进行迁移时，我得到的错误是：

我的干草堆连接：

HAYSTACK_CONNECTIONS = {
'default': {
    'ENGINE': 'haystack.backends.whoosh_backend.WhooshEngine',
    'PATH': os.path.join(base(), 'whoosh_index')
  },
}

我的模型.py：

 from django.contrib.auth.models import User
 from django.db import models

 class Author(User):
      pass

 class Book(models.Model):
      title = models.CharField(max_length=300)
      author = models.ForeignKey(Author)
      isbn = models.CharField(max_length=300)
      resume = models.TextField()

      def __unicode__(self):
          return self.title

有关更多信息，我通过 django pip install 方法在我的 django 项目中安装 haystack 和 whoosh，如下所示：

pip install haystack
pip install whoosh

回溯很清楚：

File "C:\Users\Samad Talukder\Desktop\django-env\search\search\settings.py", line 80, in <module>
    'PATH': os.path.join(base(), 'whoosh_index')
    NameError: name 'base' is not defined

这意味着您的 settings.py 文件的第 80 行使用了一个未定义的名称（base - 显然应该是一个函数）。您的设置文件缺少导入或函数定义。 base 应该做什么等超出了我们的知识范围（它绝对不是内置的，并且在 django 设置文件中没有任何标准）但是 你 现在应该因为它是 你的项目。
