Question

我试图通过单击显示产品下方的href链接导航到我的产品页面。但是由于某种原因，生成的绝对URL给了我404。这是我到目前为止尝试过的。 models.py

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import models


# Create your models here.

class Category(models.Model):
    name = models.CharField(max_length=50)
    slug = models.SlugField(max_length=50, unique=True,
                            help_text='Unique value for product page URL, created from name.')
    description = models.TextField()
    is_active = models.BooleanField(default=True)
    meta_keywords = models.CharField("Meta Keywords", max_length=255,
                                     help_text='Comma-delimited set of SEO keywords for meta tag')
    meta_description = models.CharField("Meta Description", max_length=255,
                                        help_text='Content for description meta tag')
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return 'catalog_category', (), {'category_slug': self.slug}


    class Meta:
        ordering = ['-created_at']
        verbose_name_plural = 'Categories'



class Product(models.Model):


    name = models.CharField(max_length=255, unique=True)
    slug = models.SlugField(max_length=255, unique=True,help_text = 'Unique value for product page URL, created from name.')
    brand = models.CharField(max_length=50)
    sku = models.CharField(max_length=50)
    price = models.DecimalField(max_digits=9, decimal_places=2)
    old_price = models.DecimalField(max_digits=9, decimal_places=2,blank = True, default = 0.00)
    image = models.CharField(max_length=50)
    is_active = models.BooleanField(default=True)
    is_bestseller = models.BooleanField(default=False)
    is_featured = models.BooleanField(default=False)
    quantity = models.IntegerField()
    description = models.TextField()
    meta_keywords = models.CharField(max_length=255,help_text = 'Comma-delimited set of SEO keywords for meta tag')
    meta_description = models.CharField(max_length=255,help_text = 'Content for description meta tag')
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
    categories = models.ManyToManyField(Category)

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return 'catalog_product', (), {'product_slug': self.slug}

    def sale_price(self):
        if self.old_price > self.price:
            return self.price
        else:
            return None


    class Meta:
        ordering = ['-created_at']

urls.py

from django.conf.urls import patterns, url, include

urlpatterns = patterns('catalog.views',
                       (r'^index/$', 'index', {'template_name': 'catalog/index.html'}, 'catalog_home'),

                       (r'^category/(?P<category_slug>[-\w]+)/$', 'show_category',
                        {'template_name': 'catalog/category.html'}, 'catalog_category'),

                       (r'^product/(?P<product_slug>[-\w]+)/$', 'show_product',
                        {'template_name': 'catalog/product.html'}, 'catalog_product'),

                       (r'^static/(?P<path>.*)$', 'django.views.static.serve',
                        {'document_root': '/home/surajt/Downloads/ecommerce/static'}),
                       )

这是我在html中执行代码检查时看到的。

                拥抱

这就是在html中生成href url的方式，这就是我单击url时得到的内容。 127.0.0.1:8000/demo/category/尿布/（u'catalog_product'，％20（），％20％7Bu'product_slug'：％20u'huggies'％7D）

我做错了什么？

Answer 1

您需要通过reverse传递参数，然后还要在中间省略那些空括号，有点像这样；

from django.core.urlresolvers import reverse


def get_absolute_url(self):
    return reverse('catalog_product', kwargs={'product_slug': self.slug})

您可以在此处查看示例； https://godjango.com/67-understanding-get_absolute_url/

get_absolute_url在Django 1.7中不起作用？
