Question

我在Tango的第9章使用Django - 创建用户身份验证。在注册页面中，我可以选择上传图片。在我的管理文件中，注册后我的一切看起来都不错。我显示在用户配置文件中，它甚至显示我上传的图像： cut -d: -f4 /etc/group | tr ',' '\n' | grep -v '^$' | sort | uniq -c。但是，当我点击该图片时，这是我收到的错误消息：

Picture:     Currently: profile_images/earth.jpeg  Clear

models.py：

Page not found (404)
Request Method: GET
Request URL:    http://localhost:8000/admin/rango/userprofile/1/change/profile_images/earth.jpeg/change/
Raised by:  django.contrib.admin.options.change_view
user profile object with primary key u'1/change/profile_images/earth.jpeg' does not exist.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

views.py - 只有register（）：

from __future__ import unicode_literals

from django.db import models
from django.template.defaultfilters import slugify
from django.contrib.auth.models import User


class Category(models.Model):
    name = models.CharField(max_length=128, unique=True)
    views = models.IntegerField(default=0)
    likes = models.IntegerField(default=0)
    slug = models.SlugField(unique=True)

    def save(self, *args, **kwargs):
        self.slug = slugify(self.name)
        super(Category, self).save(*args, **kwargs)

    class Meta:
        verbose_name_plural = 'categories'

    def __str__(self):
        return self.name


class Page(models.Model):
    category = models.ForeignKey(Category)
    title = models.CharField(max_length=128)
    url = models.URLField()
    views = models.IntegerField(default=0)

    def __str__(self):
        return self.title


class UserProfile(models.Model):
    user = models.OneToOneField(User)
    website = models.URLField(blank=True)
    picture = models.ImageField(upload_to='profile_images', blank=True)

    def __str__(self):
        return self.user.username

最后，我的register.html文件：

def register(request):
    registered = False

    if request.method == 'POST':
        user_form = UserForm(data=request.POST)
        profile_form = UserProfileForm(data=request.POST)

        if user_form.is_valid() and profile_form.is_valid():
            user = user_form.save()
            user.set_password(user.password)
            user.save()

            profile = profile_form.save(commit=False)
            profile.user = user

            if 'picture' in request.FILES:
                profile.picture = request.FILES['picture']
            profile.save()
            registered = True
        else:
            print user_form.errors, profile_form.errors
    else:
        user_form = UserForm()
        profile_form = UserProfileForm()

    return render(request, 'rango/register.html',
                  {'user_form': user_form,
                   'profile_form': profile_form,
                   'registered': registered}
                  )

Answer 1

主键u'1 / change / profile_images / earth.jpeg'的用户个人资料对象不存在。

看起来您的某个网址格式可能已关闭;它可能只是想捕获1以用作查找的PK，而是捕获1/change/profile_images/earth.jpeg。

Django - Tango随着Django上传图片
