在一次admin注册中遇见了以下错误:
<class 'demo.admin.ProductAdmin'>: (admin.E108) The value of 'list_display[0]' refers to 'company__name', which is not a callable, an attribute of 'ProductAdmin', or an attribute or method on 'daquan.Product'.
<class 'demo.admin.ProductAdmin'>: (admin.E108) The value of 'list_display[1]' refers to 'category__name', which is not a callable, an attribute of 'ProductAdmin', or an attribute or method on 'daquan.Product'.
admin 代码为:
from demo.contrib import admin
from demo.models import Product
class ProductAdmin(admin.ModelAdmin):
list_display = ('company__name', 'category__name', 'product_name', 'sale_status', 'literal_code')
admin.site.register(Product, ProductAdmin)
这样写并没有出现预期的效果,而是直接报了上面的错误。
解决方法:
class ProductAdmin(admin.ModelAdmin):
list_display = ('get_company', 'get_category', 'product_name', 'sale_status', 'literal_code')
#搜索域支持双下划线关联
#search_fields =(company__name, category__name)
def get_company(self, obj):
return obj.company.name
def get_category(self, obj):
return obj.category.name
#get_company.admin_order_field = '所属公司' #准许排序
get_company.short_description = '所属公司' #修改表头字段名
也可以将两个get函数写在该models模型下。
