本文介绍了使用yaml自动生成配置和具有数字ID的实体时,Google App Engine批量加载器出现问题的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我的应用程序使用。我无法访问模型。



我有我的 bulkloader.yaml 文件由 appcfg.py create_bulkloader_config



问题是实体数字ID被导入为字符串键名称。因此,如果我导出具有例如 '62'的int ID的实体,那么它将导入为具有字符串键名称为 '61'的实体,这将拧紧Django。 / p>

Revelant bulkloader.yaml片段:

  property_map:
- property:__key__
external_name:key
export_transform:transform.key_id_or_name_as_string

我正在尝试使用bulkloader设置下载/上传od数据,我想要将数据视为易于理解的格式(如.csv)---所以使用 bulkloader.py --dump(...)不是一个可行的选择,因为它给了我的sqlite3文件,其实体内容被腌制成一行。



编辑



我试着做一些@Nick建议的例子:

  ErrorOnTransform:此时不输入数字键。 

这是否意味着我必须坚持bulkloader.py(使用该werid sqlite格式)或我搞砸了一些东西;)

import_transform:transform.create_foreign_key('auth_user',key_is_id = True)

解决方案

你有export_transform'key_id_or_name_as_string',但是你没有相应的导入转换。尝试这样:

  property_map:
- property:__key__
external_name:key
export_transform: transform.key_id_or_name_as_string
import_transform:transform.create_foreign_key('Kind',key_is_id = True)

种是配置文件中标识的类型的名称。


My application uses Django non-rel. I don't have access to model.

I have my bulkloader.yaml file autogenerated by appcfg.py create_bulkloader_config.

Problem is entities numeric ID's are being imported as string key names. So if I export entity with int ID of, for example, '62', it gets imported as entity with string key name of '61' which screws up Django.

Revelant bulkloader.yaml Fragment:

 property_map:
  - property: __key__
    external_name: key
    export_transform: transform.key_id_or_name_as_string

I'm trying to setup download/upload od data using bulkloader, and I want to have data as easy to understand format (like .csv) --- so using bulkloader.py --dump (...) is not a viable option since it gives me sqlite3 files that have entities contents pickled as a single row.

EDIT

I tried doing what @Nick suggested and I got an exception:

 ErrorOnTransform: Numeric keys are not supported on input at this time.

Does this mean that I have to stick to bulkloader.py (that uses that werid sqlite format) or I messed something? ;)

Header of Transformer:

- kind: auth_user
    connector: csv
    connector_options:
      encoding: utf-8
      skip_import_header_row: True
      print_export_header_row: True

    property_map:
      - property: __key__
        external_name: key
        export_transform: transform.key_id_or_name_as_string
        import_transform: transform.create_foreign_key('auth_user', key_is_id=True)

解决方案

You've got the export_transform 'key_id_or_name_as_string', but you don't have a corresponding import transform. Try this:

property_map:
 - property: __key__
   external_name: key
   export_transform: transform.key_id_or_name_as_string
   import_transform: transform.create_foreign_key('Kind', key_is_id=True)

Where 'Kind' is the name of the kind identified in the config file.
