Django '；非类型'；对象没有属性'；rstrip&x27；干草堆

我正在使用haystack后端solr。 我收到一个奇怪的错误“NoneType”对象没有属性“rstrip” 我已经更新了我的索引很多次，检查了版本等，但没有任何工作

这是我的SearchIndex文件：

class JobIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    post_type = indexes.CharField(model_attr='post_type',faceted=True)
    job_location = indexes.CharField(model_attr='job_location',faceted=True,null=True)
    #job_type = indexes.CharField(model_attr='job_type',faceted=True,null=True)
    company_name = indexes.CharField(model_attr='company_name',faceted=True)
    hide_company_name=indexes.BooleanField(model_attr='hide_company_name', default='false')
    hot_job = indexes.BooleanField(model_attr='hot_job', default='false')
    how_to_apply_check = indexes.CharField(model_attr='how_to_apply_check')
    how_to_apply= indexes.CharField(model_attr='how_to_apply')
    job_title = indexes.CharField(model_attr='job_title', faceted=True, boost=1.5)
    start_date = indexes.DateField(model_attr='start_date', faceted=True,null=True)
    end_date = indexes.DateField(model_attr='end_date', faceted=True,null=True)
    job_description = indexes.CharField(model_attr='job_description', faceted=False)
    country = indexes.CharField(model_attr='country', faceted=True,null=True)
    is_online = indexes.CharField(model_attr='is_online', null=True)
    industry_id = indexes.CharField(model_attr='industry_id',faceted=True,null=True)
    functional_area_id = indexes.CharField(model_attr='functional_area_id',faceted=True,null=True)
    content_auto = indexes.EdgeNgramField(model_attr='job_title')
    content_location = indexes.EdgeNgramField(model_attr='job_location')
    creation_time = indexes.DateTimeField(model_attr='creation_time')

    def get_model(self):
        return jobpost

    def prepare(self, obj):
        data = super(JobIndex, self).prepare(obj)
        data['boost'] = 1.1
        return data

    def prepare_company_name(self, obj):
        if obj.hide_company_name:
            return "Confidential"
        else:
            return obj.company_name

    def index_queryset(self,**kwargs):
        return self.get_model().objects.all()

    def prepare_job_location(self, obj):
        #return [obj.user_id for obj in obj.users.all()]
        return (obj.job_location.strip())

    def get_updated_field(self):
        return 'updated'

以及日志：

有人能帮我解决这个问题吗？

从堆栈跟踪来看，self.url似乎没有定义，这导致pysolr抛出了一个错误。检查haystack配置文件是否为Solr设置了正确的url
