我想知道我是怎麼能夠使用外鍵瓶坯例如Search_fields Django的蟒蛇
class Product(models.Model):
name = models.CharField(max_length = 127)
description = models.TextField()
code = models.CharField(max_length = 127)
def __unicode__(self):
return self.name + " - " + self.code
class ProductLot(models.Model):
product = models.ForeignKey(Product)
code = models.CharField(max_length = 30)
lot_no = models.CharField(max_length = 30)
location = models.CharField(max_length = 127)
incoming = models.IntegerField()
commited = models.IntegerField()
available = models.IntegerField()
reorder = models.IntegerField()
created_date = models.DateField(auto_now_add=True)
def __unicode__(self):
return self.code + " - " + self.product.name + " - " + self.lot_no
class LotComment(models.Model):
product_lot = models.ForeignKey(ProductLot)
comment_user = models.ForeignKey(User, null=True)
comment_text = models.TextField()
created_date = models.DateField(auto_now_add=True)
def __unicode__(self):
return self.product_lot.product.code + " - " +
self.product_lot.product.name + " - " +
self.product_lot.lot_no + " - " + str(self.created_date)
搜索比我的admin.py文件我有
from CMS.Inventory.models import Product
class padmin(admin.ModelAdmin):
search_fields=['name', 'description', 'code', 'lot_no' ]
admin.site.register(Product, padmin)
,但我希望'LotComments'能夠使用'產品'可以用於代碼的相同搜索字段。
希望我解釋這口井
