我在使用python 2.7.9-2 amd64的Debian 8系统上遇到了问题:

我正在尝试构建一个包含卡片状物品的网格.每种类型的单元格(标题,图像,文本,按钮,......)每行应具有相同的高度,由最大单元格的内容决定,如下面的代码段所示.

现在我试图限制列的数量,并让卡片换行,就好像我flex-wrap: wrap;在基于flexbox的解决方案中使用的那样.列数应通过媒体查询确定.如果不使用尚未支持的子网格,这可能吗？

另外,使用子网格的解决方案如何？我想它会降级到当前浏览器中高度不等的单元格？

.grid {
  display: grid;
  grid-template-rows: repeat(4, auto);
  grid-gap: 10px;
  grid-auto-flow: column;
  grid-auto-columns: auto;
}

<div class="grid">

  <h2 class="a">Header 1</h2>
  <img class="b" src="https://placekitten.com/400/100" />
  <p class="c">text
  </p>
  <button class="d">Button</button>

  <h2 class="a">Header 2 is longer and may span multiple lines</h2>
  <img class="b" src="https://placekitten.com/400/100" />
  <p class="c">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Duis et cursus ligula. Maecenas non pharetra dui, eu tincidunt mi. Vivamus vitae luctus risus. Etiam vehicula sem est.

我有我的用户模型(AbstractBaseUserDjango 1.5)我使用电子邮件作为用户名进行身份验证,并ModelResource为我的API提供以下内容

class CartItemResource(ModelResource):
    product = fields.ForeignKey(CartItemRelatedResource, 'product', full=True)

    class Meta:
        queryset = CartItem.objects.all()
        resource_name = 'cart_item'
        excludes = ['creation_date', 'modification_date']
        allowed_methods = ['post', 'get', 'delete']
        authorization = CartAuthorization()
        authentication = SessionAuthentication()

当向API发出GET请求时,我得到:

'用户'对象没有属性'用户名'

编辑用户模型:

class User(AbstractBaseUser):
    objects = UserManager()
    name = models.CharField(max_length=100)
    email = models.EmailField(
        max_length=255,
        unique=True,
    )
    phone = models.IntegerField(max_length=10, null=True)
    is_admin = models.BooleanField(default=False, blank=True)
    is_driver = models.BooleanField(default=False, blank=True)
    lastOrderID = models.CharField(max_length=25, null=True)

    USERNAME_FIELD = 'email'
    #REQUIRED_FIELDS = ['name','phone']
    REQUIRED_FIELDS = ['name']

我正在使用Django并希望匹配URL domain.com/w和domain.com/words.我有一个表单的配置行:

url(r'^w(ords)?$', 'app_name.views.view_words')

view_words只接受一个参数(request),但似乎Django捕获(ords)正则表达式的一部分并将其传递给视图.当我(ords)从正则表达式和访问中删除时domain.com/w,它正常工作.

Django文档和类似StackOverflow的问题,包括如何捕捉可选的URL参数,但我并不想捕捉从URL的参数.有没有办法匹配URL的可选元素而不将其作为参数捕获？
