当有人尝试使用旧/:idURL而不是首选/:friendly_id链接浏览页面时,是否可以强制执行301重定向？

显然这样的重定向有助于告诉谷歌你已经更新了链接 ..所以它停止显示旧的非友好链接.

所以前几天我遇到了极端的硬盘问题,不得不手动删除我的.gem文件夹.我试图通过进入我的项目文件夹来重建我的应用程序的宝石bundle install...我很遗憾地遇到了这个错误:

/home/xxx/.rvm/rubies/ruby-2.2.2/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- bundler (LoadError)
    from /home/xxx/.rvm/rubies/ruby-2.2.2/lib/ruby/site_ruby/2.2.0/rubygems/core_ext/kernel_require.rb:54:in `require'
    from /usr/bin/bundle:7:in `<main>'

顺便说一下,kernel_require.rb的第54行是return gem_original_require(path):

if Gem::Specification.unresolved_deps.empty? then
  RUBYGEMS_ACTIVATION_MONITOR.exit
  return gem_original_require(path)
end

以下是我的看法:

<%= javascript_include_tag "social_sharing.erb" %>

然后我有:assets/javascripts/social_sharing.erb.js其中包括一些ERB标签,如<%= post.id %>......

第一个问题是我看到此错误消息:

`Asset filtered out and will not be served: add `Rails.application.config.assets.precompile += %w( social_sharing.erb.js )` to `config/initializers/assets.rb` and restart your server

如果我遵循这些指示,然后我将获得js文件,但没有评估任何ERB标记,所以我仍然<%= post.id %>在链接的js文件中看到.

我是"项目"回购的所有者,但不知怎的,我无法推动它.

user@none ~/rails_projects/project $ git remote -v
origin  git@github.com:user/project.git (fetch)
origin  git@github.com:user/project.git (push)

这是验证检查:

user@none ~/rails_projects/project $ ssh -T git@github.com
Hi user/project! You've successfully authenticated, but GitHub does not provide shell access.

推送尝试:

user@none ~/rails_projects/project $ git push origin qa
ERROR: The key you are authenticating with has been marked as read only.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

知道如何修复此错误吗？

我在/app/asssets/images/symbols.svg上有一个svg图像,内容如下.

在我的主页面容器中生成的内容与此DIV的内容重叠:

<div class="navbar navbar-fixed-bottom"></div>

这是来自github项目的CSS(bootstrap sass)

// Fix the top/bottom navbars when screen real estate supports it
.navbar-fixed-top,
.navbar-fixed-bottom {
  position: fixed;
  right: 0;
  left: 0;
  border-width: 0 0 1px;

  // Undo the rounded corners
  @media (min-width: $grid-float-breakpoint) {
    border-radius: 0;
  }
}
.navbar-fixed-top {
  z-index: $zindex-navbar-fixed;
  top: 0;
}
.navbar-fixed-bottom {
  bottom: 0;
  margin-bottom: 0; // override .navbar defaults
}

我相信这是由于在加载页面后JS呈现内容呈现而发生的.

有没有办法解决这个问题,而不知道JS内容的垂直高度提前？

编辑

这是导航栏上方的容器DIV的CSS:

-webkit-animation-delay: 0s;
-webkit-animation-direction: normal;
-webkit-animation-duration: 0s;
-webkit-animation-fill-mode: none;
-webkit-animation-iteration-count: 1;
-webkit-animation-name: none;
-webkit-animation-play-state: running;
-webkit-animation-timing-function: …

这是我想要做的：

2.1.2 :001 > UpdateStyleRanks.perform_async

这是错误：

NoMethodError: undefined method `perform' for #<UpdateStyleRanks:0x00000002f5e388>

这是我的工人：

# app/workers/update_style_ranks.rb
class UpdateStyleRanks
  include Sidekiq::Worker

  def perform
  end
end

我一直在研究这个小提琴,我想要一些建议.

如您所见,我无法在正确的位置渲染多个标记.无论我做什么,两个标记都根据htmlMarker[i]阵列中第二个标记的位置进行渲染.

谢谢你的帮助!

供参考,这是JS:

var overlay;

function initialize() {
    var myLatLng = new google.maps.LatLng(62.323907, -150.109291);
    var mapOptions = {
        zoom: 11,
        center: myLatLng,
        mapTypeId: google.maps.MapTypeId.SATELLITE
    };

    var gmap = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);

    function HTMLMarker(lat,lng){
        this.lat = lat;
        this.lng = lng;
        this.pos = new google.maps.LatLng(lat,lng);
    }

    HTMLMarker.prototype = new google.maps.OverlayView();
    HTMLMarker.prototype.onRemove= function(){}

    //init your html element here
    HTMLMarker.prototype.onAdd= function(){
        div = document.createElement('DIV');
        div.className = "htmlMarker";
        div.innerHTML = '<img src="http://www.vcsd.org/img/icon/red.png">';
        var panes = this.getPanes();
        panes.overlayImage.appendChild(div);
    }

    HTMLMarker.prototype.draw = …

我最近遇到过一个问题,我必须在gemfile中添加以下内容:

gem 'execjs'
gem 'therubyracer'

我必须这样做,以避免启动rails服务器时出现javascript运行时错误.我想将这个修改添加到使用rails new命令创建的所有新gemfiles中.

git add .在提交更改之前,我已经打字多年了.根据我的理解(从下面的信息中),现代的等价物将git add --ignore-removal <pathspec>更加冗长.有没有办法在即将发布的git 2.0版本中恢复旧的行为,或者至少在当前版本中将此消息静音？
