django - ElasticSearch_ModelFieldNotMappedError

Question

我正在使用Django Elasticsearch版本6.1.0，目前遇到这种错误:

django_elasticsearch_dsl.exceptions.ModelFieldNotMappedError:
  Cannot convert model field 'price' to an Elasticsearch field

这是我的 models.py

class Product(models.Model):
    description = models.CharField(max_length=100)
    price = models.DecimalField(max_digits=9, decimal_places=2)
    quantity = models.IntegerField()

这是 文档。py

from django_elasticsearch_dsl import DocType, Index
from crudapp.models import Product

product = Index('products')

@product.doc_type
class ProductDocument(DocType):
    class Meta:
        model = Product
        fields = ['description', 'price', 'quantity']

谁能帮我这个 ？

Answer 1

引起此错误的小数字段。
从字段中删除它，然后执行类似的操作。

  from django_elasticsearch_dsl import DocType, Index,fields


  class ProductDocument(DocType):
      price = FloatField(attr=None, **elasticsearch_properties)

      class Meta:
      . . .. . . . .
