Django Import-export TypeError: clean() got an unexpected keyword argument 'row'

Question

导入 csv 文件时出现以下错误。我认为这与日期小部件有关？

这是我的 csv 示例：

" , ICE, France, EST Current, HD, 4.59, EUR, GROSS, 01/01/08, test"

Traceback (most recent call last):
File "/usr/local/lib/python3.6/site-packages/import_export/resources.py", line 662, in import_row
self.import_obj(instance, row, dry_run)
File "/usr/local/lib/python3.6/site-packages/import_export/resources.py", line 516, in import_obj
self.import_field(field, obj, data)
File "/usr/local/lib/python3.6/site-packages/import_export/resources.py", line 499, in import_field
field.save(obj, data, is_m2m)
File "/usr/local/lib/python3.6/site-packages/import_export/fields.py", line 110, in save
cleaned = self.clean(data)
File "/usr/local/lib/python3.6/site-packages/import_export/fields.py", line 66, in clean
value = self.widget.clean(value, row=data)
TypeError: clean() got an unexpected keyword argument 'row'

资源是这样构建的 正如我所说，我无法确定引发此错误的小部件是什么。这就是为什么我将所有 Class 粘贴在这里：（我知道太长了）

class retailResource(ModelResource):
    client = fields.Field(
        column_name='client',
        attribute='client',
        widget=widgets.ForeignKeyWidget(Client, 'name')
    )
    country = fields.Field(
        column_name='country',
        attribute='country',
        widget=widgets.ForeignKeyWidget(Country, 'name')
    )
    catalogue_type = fields.Field(
        column_name='catalogue_type',
        attribute='catalogue_type',
        widget=widgets.ForeignKeyWidget(CatalogueType, 'name')
    )
    currency_in_report = fields.Field(
        column_name='currency_in_report',
        attribute='currency_in_report',
        widget=widgets.ForeignKeyWidget(Currency, 'iso3_code')
    )
    start_date = fields.Field(
        attribute='start_date',
        widget=fields.Field(
            attribute='start_date',
            column_name='start_date',
            widget=widgets.DateWidget('%d/%m/%Y'))
    )
    end_date = fields.Field(
        attribute='end_date',
        widget=widgets.DateWidget('%d/%m/%Y')
    )

    class Meta():
        model = RetailPrice
        fields = ('id','client', 'country', 'catalogue_type','quality','gross_retail_price',
                  'currency_in_report','reported_as','start_date','end_date','comments',)
        export_order = ['id','client', 'country', 'catalogue_type','quality','gross_retail_price',
                  'currency_in_report','reported_as','start_date','end_date','comments']
        import_id_fields = ('id',)

管理员是这样的

class retailAdmin(ImportExportModelAdmin):
    resource_class = retailResource
  [...]

Answer 1

所以是的，问题是将 widget=widgets.DateWidget 用于日期字段。我删除了那部分资源，就这样留下了。它起作用了。所以，这个方法行得通。

class retailResource(ModelResource):
    client = fields.Field(
        column_name='client',
        attribute='client',
        widget=widgets.ForeignKeyWidget(Client, 'name')
    )
    country = fields.Field(
        column_name='country',
        attribute='country',
        widget=widgets.ForeignKeyWidget(Country, 'name')
    )
    catalogue_type = fields.Field(
        column_name='catalogue_type',
        attribute='catalogue_type',
        widget=widgets.ForeignKeyWidget(CatalogueType, 'name')
    )
    currency_in_report = fields.Field(
        column_name='currency_in_report',
        attribute='currency_in_report',
        widget=widgets.ForeignKeyWidget(Currency, 'iso3_code')
    )
 class Meta():
        model = RetailPrice
        fields = ('id','client', 'country', 'catalogue_type','quality','gross_retail_price',
                  'currency_in_report','reported_as','start_date','end_date','comments',)
        export_order = ['id','client', 'country', 'catalogue_type','quality','gross_retail_price',
                  'currency_in_report','reported_as','start_date','end_date','comments']
        import_id_fields = ('id',)

Answer 2

如果要覆盖行条目中使用的日期格式，则必须使用 DateWidget。

它是可选的：如果你不使用 DateWidget 那么逻辑仍然会在幕后使用 DateWidget，但会依赖于你在 settings.DATE_INPUT_FORMATS 中声明的格式.我希望这就是当您删除 widget=DateTimeWidget()

时它起作用的原因

查看您的原始代码，注意 widget 的声明如何包含 Field 声明，这显然是不正确的。如果您更正此问题，我认为它会正常工作。

    start_date = fields.Field(
        attribute='start_date',
        widget=fields.Field(
            attribute='start_date',
            column_name='start_date',
            widget=widgets.DateWidget('%d/%m/%Y'))
    )
