小编Ada*_*dam的帖子

可能是一个微不足道的问题,但我正在寻找一种方法来说明获取网站网址的根,例如:http://localhost/some/folder/containing/something/here/or/there应该返回http://localhost/

我知道有,$_SERVER['DOCUMENT_ROOT']但那不是我想要的.

我确信这很容易,但我一直在阅读:这篇文章试图找出我应该使用或调用的内容.

想法？

我所遇到的另一个问题是 - 这将是答案是什么,在网站上工作,http://subsite.localhost/some/folder/containing/something/here/or/there所以我的最终结果是http://subsite.localhost/

我制作了一个composer.json脚本.

当我跑sudo composer install,我得到这个错误:

[Seld\JsonLint\ParsingException]               
"./composer.json" does not contain valid JSON  
Parse error on line 1:                         
"repositories": [    {        "t               
--------------^                                
Expected one of: 'EOF', '}', ',', ']'          

这是JSON:

"repositories": [
    {
        "type":"package",
        "package": {
          "name": "AdamKyle/Aisis-Core",
          "version":"development",
          "source": {
              "url": "https://github.com/AdamKyle/Aisis-Core.git",
              "type": "git",
              "reference":"development"
            }
        }
    }
],
"require": {
    "AdamKyle/Aisis-Core": "development"
}

如何更好地描述此JSON是如何错误的？

我已经看到了很多这些问题,但他们的解决方案都没有对我有用.我有一个这样的测试:

describe RolesController do
  describe "#delet" do 

    context "When the user is logged in" do 
      let(:user) {FactoryGirl.create(:user)}
      let(:admin) {FactoryGirl.create(:admin)}
      let(:adminRole) {FactoryGirl.create(:adminRole)}

      it "Should allow admins to delete roles" do 
        sign_in admin
        put :destroy, :id => adminRole.id
      end
    end
  end
end

简单,简单,简单.但我得到了典型的错误:

  1) RolesController#delet When the user is logged in Should allow admins to delete roles
     Failure/Error: Unable to find matching line from backtrace
     SystemStackError:
       stack level too deep
     # /home/adam/.rvm/gems/ruby-2.0.0-p247/gems/activesupport-4.0.0/lib/active_support/notifications/instrumenter.rb:23

而且我都喜欢......什么？我再次阅读了几十个关于此问题的问题,这似乎与工厂女孩有关,但我看不出这里的问题是什么.我有很多其他测试实例化像这样的工厂女孩​​对象没有问题.
