Django进出口选择字段

Question

我有一个带有选择列表（models.py）的模型：

class Product(models.Model):
    ...
    UNITS_L = 1
    UNITS_SL = 2
    UNITS_XL = 3
    PRODUCT_SIZE_CHOICES = (
    (UNITS_L, _('L')),
    (UNITS_SL, _('SL')),
    (UNITS_XL), _('XL'),
    )
    product_size = models.IntegerField(choices=PRODUCT_SIZE_CHOICES)
    ...

我还添加了一个新类，用于导出所需的fields（admin.py）：

from import_export import resources, fields
...
Class ProductReport(resources.ModelResource):
    product_size = fields.Field()

    class Meta:
        model = Product

    #I want to do a proper function to render a PRODUCT_SIZE_CHOICES(product_size)

    def dehydrate_size_units(self, product):
        return '%s' % (product.PRODUCT_SIZE_CHOICES[product_size]) 

    fields = ('product_name', 'product_size')

Class ProductAdmin(ExportMixin, admin.ModelAdmin):
    resource_class = ProductReport

但这是行不通的。如何通过Django import-export 获取PRODUCT_SIZE_CHOICESin 的命名值export？

Answer 1

您可以在Django Admin中使用“ get_FOO_display”实现此目的：

class ProductReportResource(resources.ModelResource):
    product_size = fields.Field(
        attribute='get_product_size_display',
        column_name=_(u'Product Size')
    )
