Django import-export choices field

Question

I have a model with choices list (models.py):

class Product(models.Model):
    ...
    UNITS_L = 1
    UNITS_SL = 2
    UNITS_XL = 3
    PRODUCT         


        

Answer 1

You can use 'get_FOO_display' to achieve this in the Django Admin:

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

Answer 2

Another solution:

class BaseModelResource(resources.ModelResource):

    def export_field(self, field, obj):
        field_name = self.get_field_name(field)
        func_name = 'get_{}_display'.format(field_name)
        if hasattr(obj, func_name):
            return getattr(obj, func_name)
        return super().export_field(field, obj)


class ProductReportResource(BaseModelResource):
    ...
