当我尝试从表单上传图片时,一切都会处理,但图像没有保存.

有谁知道为什么会这样？

提前谢谢!

models.py:

class Photo(models.Model):
    user = models.ForeignKey(MyUser, null=False, blank=False)
    category = models.ForeignKey("Category", default=1, null=True, blank=True)
    title = models.CharField(max_length=30, null=True, blank=True)
    description = models.TextField(max_length=120, null=True, blank=True)
    image = models.ImageField(upload_to='user/photos/', null=True, blank=True)
    slug = models.SlugField(null=True, blank=True)
    active = models.BooleanField(default=True)
    timestamp = models.DateTimeField(auto_now_add=True, auto_now=False, null=True)
    updated = models.DateTimeField(auto_now_add=False, auto_now=True, null=True)

    class Meta:
        unique_together = ('slug', 'category')
        ordering = ['-timestamp']

    def __unicode__(self):
        return "%s" %(self.user)

views.py:

def photo_upload_view(request, username):
    u = MyUser.objects.get(username=username)

    if request.method == 'POST':
        form = PhotoUploadForm(request.POST, request.FILES)
        if form.is_valid(): …

当我尝试在URL中显示用户名时,出现此错误:

使用参数'()'和未找到关键字参数'{}'来反转'account_home'.尝试了1种模式:['/(？P\w +)/ $'].

这是我的views.py

@login_required
def account_home(request, username):
    u = MyUser.objects.get(username=username)
    return render(request, "accounts/account_home.html", {})

这是我的urls.py

urlpatterns += patterns('accounts.views',
    # url(r'^account/$', 'account_home', name='account_home'),
    url(r'^/(?P<username>\w+)/$', 'account_home', name='account_home'),
    url(r'^logout/$', 'auth_logout', name='logout'),
    url(r'^login/$', 'auth_login', name='login'),
    url(r'^register/$', 'auth_register', name='register'),
)

这是它尝试渲染的代码,但不能.

预先感谢您的帮助!

有人可以指导我在我的 Django 项目中安装 CKEditor 的正确方向吗？我对此很陌生，所以解释得越彻底，对我就越有帮助。

我找到了这个链接，但它对我来说不是很好：http : //docs.ckeditor.com/# ! / guide/dev_installation。

非常感谢！

在“ send_mail”功能下，我想更改“开始”变量以在电子邮件中将日期/时间显示为MM / DD / YYYY-HH：MM AM / PM。有人知道该怎么做吗？

先感谢您！
