Django没有反向匹配，上下文破坏我的代码

Question

我已经把它缩小到当我添加上下文到我的返回渲染(请求)行是当我的代码中断，但我不知道为什么。我不知道应该给出什么错误，也不知道你需要我代码的哪一部分，但是给你。

这是我的代码。如果有帮助的话。这是我的views.py文件

from django.shortcuts import render
from .models import Category, Photo
from django.db import models

# Create your views here.
def photogallery(request):
categories = Category.objects.all()
photos = Photo.objects.all()
context = {'categories': categories, 'photos': photos}
return render(request, 'picturegallery/pictures.html', context)
def viewPhoto(request, pk):
photo = Photo.objects.get(id=pk)
return render(request,'picturegallery/photo.html', {'photo': photo})
def addPhoto(request):
return render(request,'picturegallery/ADD.html')

这是我的models.py文件

from django.db import models

# Create your models here.

class Category(models.Model):
name = models.CharField(max_length=100, null=False, blank=False)
def __str__(self):
return self.name
class Photo(models.Model):
category = models.ForeignKey(Category, on_delete=models.SET_NULL, null=True, blank=True)
image = models.ImageField(null=False, blank=False)
description = models.CharField(max_length=500, null=False, blank=False)
def __str__(self):
return self.description

这是URL.py文件

from django.urls import path, include
from . import views
from django.conf.urls import url
from django.contrib import admin
urlpatterns = [
url('gallery', views.photogallery, name="gallery"),
url('photo', views.viewPhoto, name="photo"),
url('add/', views.addPhoto, name="add"),
]

Answer 1

在我的URL.py文件中。我把代码修改成这样，它工作了。

urlpatterns = [
path('gallery', views.photogallery, name="gallery"),
path('photo/<str:pk>/', views.viewPhoto, name="photo"),
path('add/', views.addPhoto, name="add"),
]
