软件:
Python3.6.2
Django1.11
Django的进出口== 0.5.1
OSX10.12.6
INSTALLED_APPS:
THIRD_PARTY_APPS = [
...,
'reversion', # django-reversion
'import_export', # django-import-export
]
要求:
1.模型有reversion
2.模型可以做import
3.每个导入的角色都有上传者created_user
和updated_user
(但是,就目前而言,我让它从Excel文件中读取,这是问题所在)
尝试:
1.由于严格的meta
课程,其中2项要求会受到严重影响。然后我应用reichert

解决方案是我必须将id
字段公开给文件:(
ZIPCODE_BASIC_FIELDS = [
'id', # Add
'zipcode',
'region',
'prefecture',
'city',
'town',
'building',
]
class ZIPCodeAddressResource(resources.ModelResource):
zipcode = fields.Field(widget=widgets.CharWidget())
created_user = fields.Field(column_name='created_user', attribute='created_user', widget=widgets.ForeignKeyWidget(User, 'username'))
updated_user = fields.Field(column_name='updated_user', attribute='updated_user', widget=widgets.ForeignKeyWidget(User, 'username'))
class Meta:
model = ZIPCodeAddressImportExport
# exclude = ['id', ] # Need to remove this line
fields = IMPORT_COLUMNS
skip_unchanged = True
report_skipped = True
import_id_fields = ['id', ] # Let it had 'id'
export_order = IMPORT_COLUMNS
答案 1 :(得分:0)
请参阅此答案,它将排除您的ID,并且如果您愿意,还可以包括任何外键 Exclude id from import in Django import-export Csv
