小编Use*_*511的帖子

您好我想发送电子邮件激活使用django registration redux.

这是我的setting.py

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'

ACCOUNT_ACTIVATION_DAYS = 3
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = 'blahblah@gmail.com'
EMAIL_HOST_PASSWORD = 'blahpassword'
EMAIL_PORT = 465
EMAIL_USE_SSL = True

LOGIN_REDIRECT_URL = '/'

当我尝试

python manage.py shell

来自django.core.mail导入send_mail

send_mail('测试','这是测试','youremail @ gmail.com',['toemail@gmail.com'])

我收到这样的错误:

    Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/home/apsijogja/djangogirls/myvenv/local/lib/python2.7/site-packages/django/core/mail/__init__.py", line 62, in send_mail
    return mail.send()
  File "/home/apsijogja/djangogirls/myvenv/local/lib/python2.7/site-packages/django/core/mail/message.py", line 286, in send
    return self.get_connection(fail_silently).send_messages([self])
  File "/home/apsijogja/djangogirls/myvenv/local/lib/python2.7/site-packages/django/core/mail/backends/smtp.py", line 92, in send_messages
    new_conn_created = self.open()
  File "/home/apsijogja/djangogirls/myvenv/local/lib/python2.7/site-packages/django/core/mail/backends/smtp.py", line 50, in open
    self.connection …

7和python 2.7.我想在django注册中添加额外的字段.我试着像我这样扩展我的模型:

class Seller(models.Model):
user            = models.ForeignKey(User, unique=True)
name            = models.CharField(max_length=25)
phone_number    = models.BigIntegerField()
email           = models.EmailField(max_length=75)

def __str__(self):
    return self.name;

我添加像这样的form.py

    from django import forms
    from registration.forms import RegistrationForm
    from django.forms import ModelForm
    from django.contrib.auth.models import User
    from kerajinan.models import Product, Category, Seller

    class SellerForm(forms.ModelsForm):
        class Meta:
            model   = Seller
            fields  = ('name','phone_number','email')

并修改url.py,如下所示:

url(r'^accounts/', 'registration.views.register',{'form_class':SellerForm,'backend': 'registration.backends.default.DefaultBackend'})

如何使用这些模型与django注册,我得到我的ulr.py错误语法？

谢谢

我有代码来创建 slug 自动使用slugify。但是当我编辑标题时，不会用新标题生成。

这是代码model.py

class Tag(models.Model):

title           = models.CharField(max_length=50)
slug            = models.CharField(max_length=200, null=True, blank=True)
description     = models.TextField()
created_date    = models.DateTimeField(auto_now_add=True)
published_date  = models.DateTimeField(blank=True, null=True)

def publish(self):
    self.published_date = timezone.now()
    self.save()

def save(self):
    if not self.slug:
        self.slug = slugify(self.title)
    return super(Tag, self).save()

def __str__(self):
    return self.title

你能帮忙解决这个问题吗？

当我尝试运行时，收到有关 Django 模型的错误makemigrations：

您正在尝试向所有者添加一个不可为空的字段“person”，但没有默认值；我们不能这样做（数据库需要一些东西来填充现有的行）。
请选择修复：

1. 现在提供一次性默认值（将在所有现有行上设置）
2. 退出，让我在 models.py 中添加默认值

我正在使用 Django 1.8，这是我的模型：

class Person(models.Model):
    user            = models.OneToOneField(User)
    alphanumeric    = RegexValidator(r'^[0-9a-zA-Z]*$', message='hanya yang mengandung karakter alphanumeric')
    email           = models.EmailField(verbose_name='email address', unique=True, max_length=244)
    username        = models.CharField(unique=True, max_length=20, validators=[alphanumeric])
    first_name      = models.CharField(max_length=30, null=True, blank=True)
    last_name       = models.CharField(max_length=30, null=True, blank=True)
    date_of_birth   = models.DateTimeField()
    date_joined     = models.DateTimeField(auto_now_add=True)


    USERNAME_FIELD      = 'username'
    REQUIRED_FIELDS     = ['email']

    def get_full_name(self):
        fullname = self.first_name+" "+self.last_name
        return self.fullname

    def get_short_name(self):
        return self.username

    def list_operator(self):
        return self.operators.all()

    def __str__(self):
        return self.email …

您好我想在admin django中制作上传图片,但是当我使用media_root和媒体网址图片无法上传时.这是model.py

class Product(models.Model):
    category        = models.ForeignKey('Category')
    userprofile     = models.ForeignKey('UserProfile')
    title           = models.CharField(max_length=50)
    price           = models.IntegerField()
    image           = models.ImageField(upload_to=settings.MEDIA_ROOT)
    description     = models.TextField()
    created_date    = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.title;

setting.py

MEDIA_ROOT  = '/static/images/upload/'
MEDIA_URL   = '/upload/'

view.py

def home(request):
    posts = Product.objects.filter(created_date__isnull=False)
    return render(request, 'kerajinan/product_list.html', {
        'posts'         : posts,
        'categories'    : Category.objects.all(),
    })

这是tamplate product.html

<img src="{{post.image.url}}" alt="" />

你能帮我解决这个问题吗？
