设置我在容器margin: 0 5px上.item和margin: 0 -5px容器上使用的flexbox项目之间的最小距离.对我来说,这似乎是一个黑客,但我找不到更好的方法来做到这一点.

例

#box {
  display: flex;
  width: 100px;
  margin: 0 -5px;
}
.item {
  background: gray;
  width: 50px;
  height: 50px;
  margin: 0 5px;
}

<div id='box'>
  <div class='item'></div>
  <div class='item'></div>
  <div class='item'></div>
  <div class='item'></div>
</div>

我在vim中的colorscheme有问题:

替代文字http://new.tinygrab.com/ca56d2c7a8e13f7077012bece6abd90e.png

行号太靠近代码了.如何增加行数右边距的宽度？

我使用Katz的Bundler来管理gem依赖.

谁知道,如何告诉TextMate忽略"Go to File"中的"vendor/bundler_gems"文件夹？

图像展示了我的小问题.

你可以看到,我想找到我的application.sass,而不是"转到文件"找到很多来自bundler文件夹的垃圾.

在ApplicationHelper中我有这样的代码:

def inside_layout layout = 'application', &block
  @template.instance_variable_set '@content_for_layout', capture(&block)
  concat \
    @template.render :file => "layouts/#{layout}", :use_full_path => true
end

其行为如下:

application.html.haml:

!!!
%html
  %head
    ...
  %body
    = yield

common_pages.html.haml:

- inside_layout do
  ...

然后,common_pages布局在应用程序布局中呈现.

我如何用RSpec测试这个助手？

当我从spec文件中调用inside_layout时:

helper.inside_layout { }

RSpec说错误:

ActionView::MissingTemplate in 'ApplicationHelper inside_layout should render nested layout within application layout'
Missing layout layouts/application.erb in view path

但应用程序运行正常.

我正在尝试将pg_trgm模块加载到PostgreSQL,但出了点问题:
