Question

我一直在努力制作一个网站，人们可以在餐厅上发表评论。我完成了urls.py，views.py，models.py和html文件的创建。我试图将列表页面与每个餐厅的详细页面联系起来。因此，我使用str：pk标记将列表页面与详细信息页面连接起来。但是，它不起作用，但是我检查一次，却找不到错误发生的原因。

设置和其他设置已经完成。我只需要调整应用程序文件。

我的目标：餐厅列表已创建。我希望用户能够通过单击“ {{list.outline}}
”

下面的按钮进入详细信息页面

models.py

from django.db import models
from  django.utils import timezone

stars = [
    (1,"☆"),
    (2,"☆☆"),
    (3,"☆☆☆"),
    (4,"☆☆☆☆"),
    (5,"☆☆☆☆☆")
]
# Create your models here.
class Tabelog(models.Model):
    store_name = models.CharField("店名",max_length = 124,primary_key=True)
    title = models.CharField("タイトル",max_length = 124,null=True,blank=True)
    evaluation = models.IntegerField("評価",choices = stars)
    comment = models.TextField("口コミ")
    create_date = models.DateField("口コミ投稿日",default=timezone.now)
    price = models.PositiveIntegerField("値段",help_text='円',default=0)

    def outline(self):
        return self.comment[:10]

    def __str__(self):
        return ("{},{},{}".format(self.store_name,self.evaluation,self.comment[:10]))

urls.py

from django.urls import path,include

Answer 1

该问题是由从列表页面连接的详细信息页面引起的。我意识到错误消息不一定显示具体原因。
