问题描述
我有以下模型:
class Supplier(models.Model):
unique_id = models.IntegerField(unique=True)
name = models.CharField(max_length=255, unique=True)
address = models.CharField(max_length=255, blank=True, null=True)
email = models.EmailField(blank=True, null=True)
telephone = models.CharField(max_length=15, blank=True, null=True)
class PaymentMethod(models.Model):
unique_id = models.CharField(max_length=3)
supplier = models.ForeignKey(Supplier, null=True)
last_updated = models.DateTimeField(auto_now=True)
为此,我尝试为供应商添加用于付款方式的过滤器:
For which I trying to add a filter to suppliers for payment method:
@admin.register(Supplier)
class SupplierAdmin(admin.ModelAdmin):
list_display = ('unique_id', 'name', 'last_updated')
ordering = ('unique_id',)
list_filter = ('payment_method__unique_id')
inlines = [PaymentMethodInline, ]
但是,当我遇到以下错误时,我似乎错误地指定了list_filter:
However I seem to have the list_filter incorrectly specified as I get the below error:
<class 'etariff.admin.SupplierAdmin'>: (admin.E116) The value of 'list_filter[1]' refers to 'payment_method__unique_id', which does not refer to a Field.
推荐答案
要使用相关的付款方式,您可以
To use the related payment methods, you can do
list_filter = ('paymentmethod',)
请注意没有下划线,请记住后面的逗号使其成为一个元组。
Note there is no underscore, and remember the trailing comma to make it a tuple.
如果要显示唯一的ID相关的付款方式,那么我认为您必须编写自己的 ListFilter
类。请参阅文档一个例子。
If you want to display the unique ids of related payment methods, then I think you'll have to write your own ListFilter
class. See the docs for an example.
