这是我的Gemfile

gem 'haml'
group :development do
  gem 'hpricot'
  gem 'ruby_parser'
end

然后我在终端/命令窗口中执行以下语句:

bundle install
rails generate devise:views users -e haml

要么

rails generate devise:views users -t = haml

但是在erb中创建设计视图.如何解决这个问题？

在我从文件中引发执行此错误时version.py有一种方法get_git_version()./manage.py runserverversion.py

提出ValueError("找不到版本号!")

def get_git_version(abbrev=4):
    # Read in the version that's currently in RELEASE-VERSION.

    release_version = read_release_version()

    # First try to get the current version using "git describe".

    version = call_git_describe(abbrev)

    # If that doesn't work, fall back on the value that's in
    # RELEASE-VERSION.

    if version is None:
        version = release_version

    # If we still don't have anything, that's an error.

    if version is None:
        raise ValueError("Cannot find the version number!")

    # If the …

class MyClass(Object):

    def __init__(self, x=None):
        if x:
            self.x = x
    def do_something(self):
        print self.x

现在我有两个对象

my_class1 = MyClass(x)

my_class2 = MyClass()

我想在调用my_class2对象时使用x

与其他语言一样支持静态变量,如java,c ++等.

我已经安装了Wordpress v3.3.2,然后安装了SlideDeck2插件.它工作得很好.

之后我安装了Role Scoper插件版本1.3.57.

现在,我的网站上的幻灯片放映(SlideDeck2)仅对登录用户可见,当注销时,只有iframe可见且图像不可见.如果我禁用Role Scoper插件,则再次显示幻灯片放映.

现在,幻灯片放映仅在我登录或者角色Scoper插件未激活时才可见.

如何解决这个冲突？任何帮助？

由于django模板中没有模数(%)所以如何在此应用循环

{% for story in data %}
   {{forloop.counter}}

当forloop.counter%4 == 1时,应执行此操作

    <div class="thumb">
    <a href="#"><img src="{{ STATIC_URL }}images/thumb.jpg" width="185" height="185" /></a>
    </div>
    <div class="thumbFooter">
    <span class="view">
    <a href="#" class="viewIcon">{{ story.views }}</a>
    </span>
    <span class="like">
    <a href="#" class="likeIcon">{{ story.likes }}</a>
    </span>
    </div>

    </li>

当forloop.counter%4 == 2或3然后这个

    <li>
    <div class="thumb">
    <a href="#"><img src="{{ STATIC_URL }}images/thumb.jpg" width="185" height="185" /></a>
    </div>
    <div class="thumbFooter">
    <span class="view">
    <a href="#" class="viewIcon">{{ story.views }}</a>
    </span>
    <span class="like">
    <a href="#" class="likeIcon">{{ story.likes }}</a>
    </span>
    </div>
    </li>
