我正在尝试将大海捞针搜索添加到我的base.html,以便在我的网站上全局包含它。但是当我提交搜索时它会出错
我得到了:
Django-Haystack:' NoneType'对象没有属性' _default_manager'
我已将其添加到INSTALLED_APPS和我的urls.py. ./manage.py rebuild_index运行正常。
models.py:
class Site(models.Model):
site_name = models.CharField(max_length=100, blank=False, null=False)
site_manager = models.CharField(max_length=100, blank=False, null=False)
address_1 = models.CharField(max_length=100, blank=False, null=False)
address_2 = models.CharField(max_length=100, blank=True, null=True)
address_3 = models.CharField(max_length=100, blank=True, null=True)
town_city = models.CharField(max_length=100, verbose_name='Town/City')
county = models.CharField(max_length=100, blank=False, null=False)

creation = models.DateField(auto_now_add=True)
last_modified = models.DateField(auto_now=True)
def __unicode__(self):
return self.site_name

text = indexes.CharField(document=True, use_template=True)
site_name = indexes.CharField(model_attr='site_name')
site_manager = indexes.CharField(model_attr='site_manager')

错误是因为您的Haystack版本不支持您的Django版本。如果你想使用Django 1.9 +
,你需要升级你的django-haystack版本在Haystack 2.5中添加了对Django 1.9的支持,并在Haystack 2.5.1中添加了对Django 1.10的支持。

您可以从github安装最新版本(如信号回答),但使用pip:
pip uninstall django-haystack
pip install -e git+https://github.com/django-haystack/django-haystack.git#egg=django-haystack

我通过安装github的最新版本(目前为2.5.dev0)解决了这个问题:
pip uninstall django-haystack
git clone https://github.com/django-haystack/django-haystack
cd django-haystack
python setup.py install
