小编Cor*_*win的帖子

我刚刚完成了xcode安装,mac osx lion.完成后,我尝试使用pip,easy_install和home brew在虚拟环境中安装PIL.这三个人都错了.pip install会出现以下错误:

pip`

unable to execute gcc-4.0: No such file or directory

error: command 'gcc-4.0' failed with exit status 1

`

easy_install的 unable to execute gcc-4.0: No such file or directory error: Setup script exited with error: command 'gcc-4.0' failed with exit status 1

家酿 Error: Failed executing: python setup.py build_ext

我不确定从哪里开始.

谢谢,CG

我正在尝试设置一个选择菜单以将 ImageGallery 与产品相关联。ImageGallery 是多态的，因为它在几个模型之间共享。Formtastic 似乎对要做什么感到非常困惑。它试图调用一个名为 Galleryable 的方法，这是我的多态关联的名称，产品模型上的 _id (galleryable_id)。

产品

class Product < ActiveRecord::Base
  has_one :image_gallery, as: :galleryable, dependent: :destroy
  accepts_nested_attributes_for :image_gallery, :allow_destroy => true
end

画廊

class ImageGallery < ActiveRecord::Base
  belongs_to :galleryable, polymorphic: true

  validates :title, presence: true

  has_many :images, as: :imageable, dependent: :destroy
  accepts_nested_attributes_for :images, :allow_destroy => true, reject_if: lambda { |t| t['file'].nil? }

end

主动管理表单

form do |f|
    f.inputs "Details" do
      f.input :name
      f.input :category
      f.input :price
      f.input :purchase_path
      f.input :video_panels
      f.input :image_panels
      f.input :image_gallery, :as => …

我正在开发一个小javascript库,需要一些ajax功能,json,jsonp和一些xml.我非常喜欢jQuery ajax方法的工作方式,但不需要所有其他jQuery工具.有没有人知道实现大部分或全部jquery功能的小型跨浏览器ajax脚本？

谢谢!

我有一个Doctrine mongodb文档,我已经变成了一个表单.该文档有两个emebedOne文档,这些文档也在表单中.主文档正在验证,但嵌入文档不是.我正在使用自定义断言,但我认为这不重要.

文献

    class AccountRecord{
    /**
     * @MongoDB\Id
     */
    private $id;

    /**
     * @MongoDB\Field(type="BimcoreEmail")
     * @Assert\Email
     * @Assert\NotNull
     * @CustomAssert\BimcoreEmail
     */
    private $email;

    /**
     * Access Admin
     * 
     * @MongoDB\Boolean
     */
    private $access_admin = 0;


    /** @MongoDB\EmbedOne(targetDocument="vidAccountSettings") */
    private $vid;
   }

嵌入式类从不调用自定义断言.

/** @MongoDB\EmbeddedDocument */
class vidAccountSettings {
    /**
     * Share section path
     *
     * 
     * @MongoDB\Field(type="Url")
     * @CustomAssert\Url
     */
    private $sharePath;
}

我已经在本地设置了carrierwave背景资源以及sidekiq和sidekiq网站.我可以看到作业被添加到sidekiq Enqueued但它们永远不会运行.什么会妨碍他们执行？

设置:Rails 3.2.11 Unicorn 4.6.1 Sidekiq 2.7.5 carrierwave 0.8.0 carrierwave_backgrounder 0.2.0

配置背景.

CarrierWave::Backgrounder.configure do |c|
  c.backend :sidekiq, queue: :carrierwave
end

模型

class EntryImage < ActiveRecord::Base
  attr_accessible :alt, :image_path

  belongs_to :imageable, :polymorphic => true

  validates :image_path, presence: true

  mount_uploader :image_path, ImageUploader
  process_in_background :image_path


end

上传

# encoding: utf-8

class ImageUploader < CarrierWave::Uploader::Base
  include ::CarrierWave::Backgrounder::Delay
  # Include RMagick or MiniMagick support:
  # include CarrierWave::RMagick
  include CarrierWave::MiniMagick

我正在使用ex_admin并遇到启动Phoenix服务器的问题.我正在与Hound建立集成测试.ex_admin在测试/支持框架中有一个Phoenix端点.当我将端点服务器的配置设置为true时,我收到一个错误:

    ** (EXIT from #PID<0.70.0>) shutdown: failed to start child: Phoenix.Endpoint.Server
   ** (EXIT) shutdown: failed to start child: {:ranch_listener_sup, TestExAdmin.Endpoint.HTTP}

           ** (EXIT) no process

谢谢你的帮助!

我运行以下代码

session = create_session(bind=db)
#define tables, if they exist sqlalchemly will find them and sycn otherwise they will be created
delivered= Table('delivered', metadata,
    Column('delivered_id',Integer,primary_key=True),
    Column('domain',String(200)),

class Delivered(object):        
    def __init__(self,obj):

report1t = Table('clicked', metadata,

    session.commit()
    session.flush()

我收到此错误sqlalchemy.exc.InvalidRequestError:没有开始事务.

我试图第一次设置Spree.一切顺利,直到我上传图片.我在Mac OSX Mountain Lion上使用自制软件安装了Imageamgick.上传任何图像会给我以下错误.

我有一个递归JSON爬虫函数,它查找指定的函数然后返回它.但是,它返回undefined,我不知道为什么.

这是脚本:

function get(what, where){
    where = typeof(where) != 'undefined' ? where : user.object;
    for(entry in where){
        if(typeof(where[entry]) =="string"){
            if (entry == what) {
                result = where[entry];
                console.log(result)
                return result;
            }
        }else if(typeof(where[entry]) =="object"){   
            get(what, where[entry]);
        }
    }
}

在console.log正确的回报,但return语句下面失败.
