在学习Django的时候，我要做一个展示页面，发现不能通过 == 来判断两个实例其中一个字段的内容一致。以下代码不报错，但是html文件的==判断所有值不相等。
models.py
class Goods_of_type(models.Model):
goods_of_type=models.CharField(max_length=20)
def str(self):
return self.goods_of_type
class Good(models.Model):
goods_of_type=models.ForeignKey(Goods_of_type,on_delete=models.CASCADE)
name=models.CharField(max_length=50)
date_added=models.DateTimeField(auto_now_add=True)
describe_of_good=models.TextField()
class Meta:
verbose_name_plural='good'
def str(self):
return self.name
views.py
def goods(request):
goods=Goods_of_type.objects.order_by()
good=Good.objects.order_by()
context={'goods':goods,"good":good}
return render(request,'goods/goods.html',context)
goods.html
{% extends 'goods/base.html' %}
{% block content %}
river的商场具有如下品类
{% for line in goods %}
