Nginx在Mavericks上工作正常,现在我升级到Yosemite后显示 nginx命令未找到,我尝试用brew install nginx安装nginx并显示错误

Error: You must brew link pcre before nginx can be installed

并brew link pcre显示

Linking /usr/local/Cellar/pcre/8.35... Error: No such file or directory - /usr/local/Cellar/pcre/8.34/share/doc/pcre

它试图链接8.34.我重新安装仍然是相同的,我如何解决它？

我是angularjs的新手,我在访问控制器中的指令属性时遇到困难.

指示

<rating max-stars="5" url="url.json"></rating>

app.directive('rating', [function () {
    return {
        restrict: 'E',
        scope: {
            maxStars: '=',
            url: '@'
        },

    link: function (scope, iElement, iAttrs) {
     console.log(iAttrs.url); //works
}

调节器

app.controller('ratingController', ['$scope', '$attrs' , '$http','$routeParams',function  ($scope,$attrs,$http,$routeParams) {


            console.log($attrs.url); //shows undefined

}]);

如何访问控制器中的url属性？

我正在尝试部署rails应用程序,但它坚持错误

我正在尝试拆分使用文本字段输入的日期。我想要它在一个数组中。

在 html 文件中

<%= text_field_tag :checkoutdate, params[:checkoutdate],:placeholder => 'Select Date', :class=>'form-control datepicker input-lg',:required=>true,"ng-model" => "checkoutdate"%>

    <p class='bg-danger' ng-show="isInvalidDate()">Check-out date cannot be lesser than check-in date</p>

在控制器 js 文件中

App.controller('validationController',['$scope', function($scope){
$scope.isInvalidDate = function(){
     var checkin = $scope.checkindate.split('-');
     var checkout = $scope.checkoutdate.split('-');

    if($scope.checkin[0]>$scope.checkout[0] || $scope.checkin[1]>$scope.checkout[1]){
        return true;
    }

}

我在控制台中收到错误

Cannot read property 'split' of undefined

我究竟做错了什么？

这是我第一个部署到heroku以外的服务器的rails应用程序.我已成功将我的rails应用程序部署到digitalocean.当我在浏览器中键入ipaddress时,会显示主页.但当我尝试重定向到其他控制器,如xxx.xxx.xxx.xx/users/sign_in它显示404 Not Found.此外,没有任何图像出现.

在/ etc/nginx的/启用的站点 - /默认

server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        server_name mydomain.com;
        passenger_enabled on;
        rails_env    production;
        root         /home/deploy/myapp/current/public;

        # redirect server error pages to the static page /50x.html
        error_page   500 502 503 504  /50x.html;
        location = / {
           passenger_enabled on; <-added this line for home page to show up
        }
        location = /users/sign_in {
           passenger_enabled on; <-added this line for sign_in view to show up
        }
}

我不知道我错过了什么.我是否必须添加passenger_enabled on; …

我正在尝试使用 :method => :delete 删除记录，但它改为调用 GET 。它重定向到 show 并显示 404 not found。但如果我返回并刷新，该记录实际上被删除了。

<% @photos.each do |photo| %>
<div class='photogallery'>
<%= link_to image_tag(photo.image_url(:thumb)) if photo.image? %>
<div class="name"><%= photo.caption %></div>
<div class="actions">
<%= link_to "edit", edit_admins_photogallery_path(photo) %> |
<%= link_to "remove",admins_photogallery_path(photo), :method => 'delete',:confirm => 'Are you sure?' %> |

</div>
</div>
<% end %>

我在尝试将 Rails 应用程序部署到生产环境时看到此错误

SSHKit::Runner::ExecuteError: Exception while executing on host xxx.xxx.xxx.xx: rake exit status: 1
rake stdout: Nothing written
rake stderr: rake aborted!
NoMethodError: undefined method `fetch' for "QLite version 3.x":String

这个错误是由 th 命令调用的

我有一个前端和管理部分。有3个角色super_admin，admin，user。使用super_admin或admin登录时，我应该能够访问/ admin /名称空间，该名称空间正在运行。但是，当我以用户身份登录时，我应该无法访问/ admin /名称空间，它应该重定向404页或索引页。我正在使用cancan限制对控制器的访问。

namespace :admin do
// admin routes
end

//Devise for user model
devise_for :users

//Role model
class Role < ActiveRecord::Base
    has_many :users 
end

//User model
class User < ActiveRecord::Base
belongs_to :role
end

//Role table columns
id name
1  super_admin
2  admin
3  user

当我以用户角色登录并转到/ admin /路径时，它将重定向到admin部分。如何仅在用户角色的路由中限制它？
