我正在使用Django创建我的第一个网站。在创建表单并将网站返回到刚刚创建的页面的详细信息页面时,我在/ books / books / add /中遇到了此NoReverseMatch问题找不到带有关键字参数'{'pk':39}'的'detail'。尝试了1种模式:['books /(?P [0-9] +)/ $我曾尝试在urls.py文件中修复我的URL,但是对此是新手,所以我无法正常工作。
urls.py file
from django.conf.urls import url
from django.contrib import admin
from . import views
app_name = 'books'
URL patterns = [
url(r'^books/$', views.index, name='index'),
url(r'^$', views.index, name='index'),
url(r'^(?P<book_id>[0-9]+)/$', views.detail, name='detail'),
url(r'books/add/$',views.BookCreate.as_view(),name='book-add'),
]
model.py file
from django.db import models
# Create your models here.
from django.core.urlresolvers import reverse
class Books(models.Model):
def get_absolute_url(self):
return reverse('books:detail', kwargs={"pk":self.pk})
def __str__(self):
return self.name + '-' + self.author
name = models.CharField(max_length=100)
author = models.CharField(max_length=100)
price = models.CharField(max_length=100)
book_image = models.CharField(max_length=1000)
您可以尝试像这样构建模型:
class Books(models.Model):
name = models.CharField(max_length=100)
author = models.CharField(max_length=100)
price = models.CharField(max_length=100)
book_image = models.CharField(max_length=1000)
def get_absolute_url(self):
return reverse('books:detail', kwargs={"pk":self.pk})
def __str__(self):
return self.name + '-' + self.author
更改此方法的来源:
def get_absolute_url(self):
return reverse('books:detail', kwargs={"pk":self.pk})
到:
def get_absolute_url(self):
return reverse('books:detail', kwargs={"book_id":self.pk})
因为您在网址中使用<book_id>
,而不是pk
。
