当我尝试提交更改时,我收到此错误:

error: object file .git/objects/31/65329bb680e30595f242b7c4d8406ca63eeab0 is empty
fatal: loose object 3165329bb680e30595f242b7c4d8406ca63eeab0 (stored in .git/objects/31/65329bb680e30595f242b7c4d8406ca63eeab0) is corrupt

不知道如何解决这个错误？

我试过git fsck我有:

error: object file .git/objects/03/dfd60a4809a3ba7023cbf098eb322d08630b71 is empty
fatal: loose object 03dfd60a4809a3ba7023cbf098eb322d08630b71 (stored in .git/objects/03/dfd60a4809a3ba7023cbf098eb322d08630b71) is corrupt

有人可以描述ERB文件中使用的以下字符的用法:

<%   %>
<%=  %>
<%  -%>
<%#  %>

每个人的用法是什么？

我在Ubuntu 11.10和RubyMine上运行我的开发

这是我对database.yml的开发设置:RubyMine为我创建的

development:
  adapter: postgresql
  encoding: unicode
  database: mydb_development
  pool: 5
  username: myuser
  password:

当我尝试运行应用程序时,我在下面收到此错误,似乎我还没有创建"项目"用户,但是,我如何创建用户并在postgres中为其授予数据库？如果这是问题,那么,在Ubuntu中为此任务使用的推荐工具是什么？如果这不是问题,那么,请指教.

我想知道将代码从SVN存储库移动到GIT存储库的推荐方法,以便我们转换开发人员团队并开始使用GIT.

我们可以进行转换并在SVN存储库中完成所有提交吗？

此外,我们的团队目前对SVN感到满意,但是,他们不知道GIT中的分支比SVN容易得多,在哪里可以找到一个证明GIT在分支方面具有强大功能的实际例子？

我使用的是simple_form gem,我有一个国家/地区集合,当我选择国家/地区时它工作正常,更新的记录将存储国家/地区ID,但是,当我尝试编辑记录时,默认情况下未选择所选国家/地区编辑表格.

以下是编辑表单中的代码:

= f.input :country_id, :collection => all_countries

simple_form不应该从db查看所选国家/地区吗？

我试图在heroku终端检测我的数据库,如下所示:

myapp@ubuntu:~/RubymineProjects/myapp$ heroku pg:info
The plugin heroku-sql-console has been deprecated. Would you like to remove it? (y/N) n
=== HEROKU_POSTGRESQL_JADE_URL (DATABASE_URL)

所以,我尝试过:

myapp@ubuntu:~/RubymineProjects/myapp$ heroku pg:psql
The plugin heroku-sql-console has been deprecated. Would you like to remove it? (y/N) n
psql (9.1.7, server 9.1.6)
SSL connection (cipher: **-**-****-**, bits: 256)
Type "help" for help.

我需要列出所有用户记录:

dbfjinfaes61gb=> …

在Rails中,我可以运行:

rake db:migrate:status

但是拉拉维尔怎么样？我怎么知道当我这样做时会运行哪些迁移:

php artisan migrate

我在生产服务器上,我需要确保我不会破坏它.

我可以看到Log facade非常有用.在laravel文档中:

记录器提供RFC 5424中定义的八个日志记录级别:紧急,警报,严重,错误,警告,通知,信息和调试.

但是,我如何记录模型的实例？例如:

$user= User::find($user_id);

那么,是否可以记录$user对象？

我已经开始使用Haxe将我的ActionScript 3项目转换为NME,但是,我想知道Neko在Linux世界中是什么？我搜索了它,我发现它是一只动画猫!

有人可以向我解释一下吗？

到目前为止,我只能判断一个属性是否被继承,但我需要知道继承的来源(例如,哪个CSS文件导致最终值？)这可能吗？

有一个方便的工具吗？

这是我在chrome Computed Style(show inheritance)中得到的内容.请参阅direction属性,没有关于其继承源的信息
