NERDTreeToggle总是让它显示在左侧.我想把它显示在右边.有可能吗？

我不确定这个问题的确切术语是什么.基本上,我需要删除远程存储库中的一些文件和目录

我在github上有一个本地git repo和远程仓库

1. 一直在自己工作.
2. 一位朋友发出拉动请求.
3. 我合并了他的请求(通过github接口)
4. 我拉了变化.
5. 我测试了代码并决定不采取他的更改(不应该在第一个地方合并)
6. 我恢复了之前的提交
7. 做了一些改变
8. 推送到服务器.

这就是我的本地存储库目前的样子:

*   7e143b1  (HEAD)
|\  
| *   18cea0f  (origin/master, origin/HEAD, master)
| |\  
| | * fc19ccf 
* | | 6f3c58a 
|/ /  
* | 8d82486 
|/  
| * d3ce65f  (pre-install-activeadmin)
|/  
* 7d0566c 
* d1c77ab 
* 75ba704 
* 30dc67c  (heroku/master)
* f89b1f6 
* ea5e2db 
* 08931d6 
* 9773a6f 
* b636aba 
* cb6f8d4 

我可以将我的本地回购改为7d0566c.我不确定我的远程仓库上的头指向哪里.

如何删除远程仓库中但不在我的本地仓库中的文件？

显然,我没有在我的本地仓库中看到他的任何文件,因为我将HEAD重置为之前的提交.但是,远程仓库仍然显示他的文件.当我提交时,它提交就好了.

我的工作流程错了吗？我应该在第一时间测试补丁.有什么建议吗？我是版本控制的新手.谢谢

我一直在尝试使用Rails,当我使用rake时,我得到了这个错误.我应该使用哪些运行时间的建议？

使用:Rails 3.0.3.

我在验证器中使用此代码:

validates_length_of :birth_date_8, :minimum => 8, :allow_nil => true, :message => "value_is_not_a_proper_date", :if =>:family_birthday? 

但是,它不允许该字段为零.我已经检查过了,这不是一件容易:if => :family_birthday?搞乱的问题.

代码有问题吗？

这是我在尝试通过Facebook登录时看到的错误,我总是看到错误.似乎无法摆脱它:

无法通过Facebook授权您,因为"Csrf已检测到".

我把一个跳过:

skip_before_filter :verify_authenticity_token

在Omniauth回调,但我仍然得到错误.这是在本地和prod(heroku)环境中.我已经设置了heroku环境变量.任何的想法？

我跟随模特:

class CapstoneMilestone < ActiveRecord::Base

  attr_accessible :capstone_id, :milestone_id, :rank, :id, :status, :statusweight, :rating, :ratingweight
  belongs_to :milestone
  belongs_to :capstone

  accepts_nested_attributes_for :capstone, :allow_destroy => false
  accepts_nested_attributes_for :milestone, :allow_destroy => false


end

class Milestone < ActiveRecord::Base

  has_many :capstone_milestones
  has_many :capstones, :through => :capstone_milestones
  attr_accessible :id, :name, :description, :department_id, :project

  accepts_nested_attributes_for :capstone_milestones, :allow_destroy => true

end

我也有一个formtastic形式:

<% semantic_form_for(@capstone_milestone) do |form| %>

    <%= form.semantic_errors :state %>
    <% form.inputs do %>
      <%= form.input :capstone_id , :as => :select, :collection => Capstone.all %>
      <%= form.input :milestone_id, …
