Question

我在我的Ubuntu服务器上使用django-haystack和elasticsearch，发现某些搜索查询只会引发错误页面，我不知道为什么会这样。任何帮助赞赏！：）

model.py:

class EnActress(models.Model):
    name = models.CharField(max_length=100, null=True)
    image_urls = models.CharField(max_length=200)
    images = models.TextField(null=True)
    actress_image = models.TextField(null=True)


class EnMovielist(models.Model):
    content_ID = models.CharField(max_length=30)
    release_date = models.CharField(max_length=30)
    running_time = models.CharField(max_length=10)
    actress = models.CharField(max_length=300)
    series = models.CharField(max_length=30)
    director = models.CharField(max_length=30)
    label = models.CharField(max_length=30)
    image_urls = models.CharField(max_length=200, null=True)
    images = models.TextField(null=True)
    image_paths = models.TextField(null=True)

search.indexes.py:

 class EnActressIndex(indexes.SearchIndex, indexes.Indexable):
         text = indexes.EdgeNgramField(document=True, use_template=True)
         en_name = indexes.CharField(model_attr='name')

         def get_model(self):
             return EnActress
         def index_queryset(self, using=None):
             return self.get_model().objects.all()

 class EnMovielistIndex(indexes.SearchIndex, indexes.Indexable):
      text = indexes.EdgeNgramField(document=True, use_template=True)
      content_ID = indexes.CharField(model_attr='content_ID')
      release_date = indexes.CharField(model_attr='release_date')
      actress = indexes.CharField(model_attr='actress')
      label = indexes.CharField(model_attr='label')

      def get_model(self):
          return EnMovielist

      def index_queryset(self, using=None):
          return self.get_model().objects.all()

这是Django的错误按摩

Failed lookup for key [actress_image] in 'EnMovielist object'

这意味着您正在查找actress_image对象的EnMovielist值。

您可能尝试做的事情需要result.object成为EnActress的实例。

渲染时VariableDoesNotExist：键[object]的查找失败
