App Engine BadValueError On Bulk Data Upload - TextProperty 被解释为 StringProperty [英] App Engine BadValueError On Bulk Data Upload - TextProperty being construed as StringProperty

问题描述

bulkoader.yaml:

bulkoader.yaml:

transformers: 
    - kind: ExampleModel 
      connector: csv 
      property_map: 
        - property: __key__ 
          external_name: key 
          export_transform: transform.key_id_or_name_as_string 
        - property: data 
          external_name: data 
        - property: type 
          external_name: type 

模型.py:

class ExampleModel(db.Model): 
        data = db.TextProperty(required=True) 
        type = db.StringProperty(required=True) 

一切似乎都很好，但是当我上传时出现此错误:BadValueError: 属性数据长度为 24788 字节；它必须是 500 或较少的.考虑使用 Text，它可以存储任意长度的字符串.

Everything seems to be fine, yet when I upload I get this error: BadValueError: Property data is 24788 bytes long; it must be 500 or less. Consider Text instead, which can store strings of any length.

出于某种原因，它认为 data 是一个字符串属性.

For some reason, it thinks data is a string property.

有人知道我该如何解决这个问题吗?

Any one know how I can fix this?

推荐答案

您需要为文本字段指定导入转换，如下所示:

You need to specify an import transform for the text field, like this:

- property: data
  external_name: data
  import_transform: db.Text
