问题描述
我想知道如何使用外键预览搜索例如
I was wondering how I am able to use a foreign key to preform a search for example
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)
比我的admin.py文件中我有
than in my admin.py file I have
from CMS.Inventory.models import Product
class padmin(admin.ModelAdmin):
search_fields=['name', 'description', 'code', 'lot_no' ]
admin.site.register(Product, padmin)
但是我想让LotComments能够使用与产品相同的搜索字段代码
but I want for 'LotComments' to be able to use the same search fields that 'Product' can as for code ect.
希望我解释得很好
推荐答案
您可以在admin search_fields
中指定相关字段搜索,方式与Django查询集相同。检查文档。对于 LotComments
对象, search_fields
将如下所示:
You can specify related field searches in the admin search_fields
the same way you do on Django querysets. Check on the documentation. For the LotComments
object, the search_fields
would look something like:
search_fields = ['product_lot__product__name',
'product_lot__product__description',
'product_lot__product__code',
'product_lot__lot_no']
