问题:Django 弹性搜索:AttributeError:类型对象“PostDocument”没有属性“Django”

我在 django 的弹性搜索中非常新...当我运行这个命令时,python3 manage.py search_index --rebuild它会触发我这个错误:我没有得到它有什么问题

File "/home/pyking/.local/lib/python3.6/site-packages/django_elasticsearch_dsl/registries.py", line 39, in register_document
    django_meta = getattr(document, 'Django')
AttributeError: type object 'PostDocument' has no attribute 'Django'

这是我的documents.py

from django_elasticsearch_dsl import DocType, Index
from blog2.models import Article

posts = Index('articles')

@posts.doc_type
class PostDocument(DocType):
    class Meta:
        model = Article

        fields = [
            'alias',
            'author',
            'title',
            'body',
            'category',
        ]

这是我的模型:

class Article(models.Model):
    alias = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    author = models.ForeignKey(Author, on_delete=models.CASCADE, related_name='author')
    title = models.CharField(max_length=200)
    body = models.TextField()
    category = models.ForeignKey(Category, on_delete=models.CASCADE)

我的代码没有出错,即使它没有触发我的代码问题,它也触发了我一些奇怪的错误..

解答

它不是Meta类,应该是Django类,您应该创建并告诉模型、字段和其他与本文档及其模型相关的配置。请参阅文档及其示例。https://github.com/sabricot/django-elasticsearch-dsl#quickstart

from django_elasticsearch_dsl import Document, Index
from django_elasticsearch_dsl.registries import registry
from blog2.models import Article

posts = Index('articles')

@registry.register_document
@posts.document
class PostDocument(Document):
    class Django:
        model = Article

        fields = [
            'alias',
            'author',
            'title',
            'body',
            'category',
        ]
