在我的Rails应用程序运行时收到此警告guard init rspec:

Warning: you have a Gemfile, but you're not using bundler or
RUBYGEMS_GEMDEPS
14:54:15 - INFO - Writing new Guardfile to
/home/ubuntu/railsprojects/sillyfish/Guardfile 14:54:16 - INFO - rspec
guard added to Guardfile, feel free to edit it

我不明白为什么会这样.可以忽略这个警告吗？

这是我的Gemfile:

source 'https://rubygems.org'

gem 'rails', '4.2.4'
gem 'pg'
gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc

group :development, :test do
  gem …

我现在正在我的应用程序中实现omniauth功能.一切正常,除了我不能从Facebook获得名字和姓氏.这是我的型号代码.

    def self.from_omniauth(auth)
    user = User.where(email: auth.info.email).first
    if user
      return user
    else
      where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
        user.provider = auth.provider
        user.uid = auth.uid
        user.first_name = auth.info.first_name
        user.last_name = auth.info.last_name
        user.email = auth.info.email
        user.image = auth.info.image
        user.password = Devise.friendly_token[0,20]
      end
    end

我已经为设计正确设置了强大的参数,因为我现在使用它进行默认身份验证并且工作正常.是否还需要来自facebook的名字和姓氏的其他权限？

我正在使用谷歌地方api自动完成位置作为用户类型.但是,我如何将建议限制在特定国家/地区？

这是我的javascript

function initAutocomplete() {

    // Create the search box and link it to the UI element.
    var input = document.getElementById('autocomplete-input');
    var searchBox = new google.maps.places.SearchBox(input);

    // [START region_getplaces]
    // Listen for the event fired when the user selects a prediction and retrieve
    // more details for that place.
    searchBox.addListener('places_changed', function() {
        var places = searchBox.getPlaces();
        if (places.length == 0) {
            return;
        }
    });
}

我遇到flex滑块问题,因为如果我使用ng-repeat,它会停止工作.否则它的工作正常.

myApp.controller('frontCtrl', function ($scope) {
  var results = {"id":4,"title":"sddddddd", "photos":[{"url":"http://placekitten.com/g/400/200","id":1},{"url":"http://placekitten.com/g/400/200","id":2}]};
  $scope.images=results.photos

});

myApp.directive('flexslider', function () {

  return {
    link: function (scope, element, attrs) {

      element.flexslider({
        animation: "slide"
      });
    }
  }
});

HTML

    <div class="flexslider" flexslider>
      <ul class="slides">

        /* This wont work*/
        <li ng-repeat="img in images">
          <img src="{{img.url}}">
        </li>


          /* This work*/
        <li>
          <img src="http://placekitten.com/g/400/200">
        </li>
        <li>
          <img src="http://placekitten.com/g/400/200">
        </li>
        <li>
          <img src="http://placekitten.com/g/400/200">
        </li>
      </ul>
    </div>

我已经在一个标题中重新创建了这个问题http://plnkr.co/edit/P2AOwQY0fQSMSXUQbc9t?p=preview

我正在尝试将payumoney支付网关集成到我的rails应用程序中.

我添加了gem active_merchant_payu_in,但是在此之后我无法启动app "warning: already initialized constant APP_PATH ".. 并且得到这个控制台错误..我发现这个模块来自于activemerchant我安装在我的gemfile而不是这个,现在我的应用程序启动.

根据文档,这是我们设置activemerchant的方式

ActiveMerchant::Billing::Base.mode = :test
      ::SAMPLEGATEWAY = ActiveMerchant::Billing::TrustCommerceGateway.new(
          :login => 'TestMerchant',
          :password => 'password')

因此,对于payu我改变了网关下面,但我应该怎么传递的,而不是:login和:password在下面的代码？

 ActiveMerchant::Billing::Base.mode = :test
  ::GATEWAY = ActiveMerchant::Billing::PayuInGateway.new(
      )

对于payumoney我们都有

商家ID,商家钥匙,商家盐

我无法在任何地方找到足够的文档.有人可以对这个话题有所了解吗？

我只是在 Rails 应用程序上试用 JWT 令牌，使用这个 jwt 库：https : //github.com/jwt/ruby-jwt

JWT.encode({sss: "333"}, 'SECRET_KEY')

返回以下令牌：

eyJhbGciOiJIUzI1NiJ9.eyJzc3MiOiIzMzMifQ.CwX_1FztYHVpyx_G27u938SceilsVc5AB5Akwqlo2HA

然后我使用上面的令牌解码

JWT.decode("eyJhbGciOiJIUzI1NiJ9.eyJzc3MiOiIzMzMifQ.CwX_1FztYHVpyx_G27u938SceilsVc5AB5Akwqlo2HA", 'SECRET_KEY')

正确返回以下响应：

[{"sss"=>"333"}, {"alg"=>"HS256"}]

但是，如果我尝试将令牌的最后一个字母更改为B而不是当前的A，它仍然返回相同的响应，这很奇怪。

JWT.decode("eyJhbGciOiJIUzI1NiJ9.eyJzc3MiOiIzMzMifQ.CwX_1FztYHVpyx_G27u938SceilsVc5AB5Akwqlo2HB", 'SECRET_KEY')

即使我提供的令牌是错误的，也会收到此响应：

[{"sss"=>"333"}, {"alg"=>"HS256"}]

实际上，我对所有字符都得到了相同的响应，直到 'D'

如果我使用F上面的和其他人，那么它会按预期显示错误：

JWT.decode("eyJhbGciOiJIUzI1NiJ9.eyJzc3MiOiIzMzMifQ.CwX_1FztYHVpyx_G27u938SceilsVc5AB5Akwqlo2HF", 'SECRET_KEY')

JWT::VerificationError（引发签名验证）来自 (irb):34

这可能是什么原因？这是预期的行为还是我在这里做错了什么？

运行时bundle exec guard收到这些警告。

它显然来自 pry gem …

我正在使用ransack进行搜索,现在我想在我的rails应用程序中实现分页.所以我使用了will_paginate gem.我面临的问题是,我无法弄清楚如何将paginate放在我当前的控制器代码中,因为它已根据查询获取结果.

这是我的控制器代码

def search
if params[:search].present? && params[:search].strip != ""
  session[:loc_search] = params[:search]
end
arrResult = Array.new
if session[:loc_search] && session[:loc_search] != ""
  @rooms_address = Room.where(active: true).near(session[:loc_search], 5, order: 'distance')
else
  @rooms_address = Room.where(active: true).all
end

@search = @rooms_address.ransack(params[:q])
@rooms = @search.result

@arrRooms = @rooms.to_a

有人能告诉我如何在这里加分吗？

用日志更新

18:29:40 web.1    |   Room Load (0.8ms)  SELECT  rooms.*, 3958.755864232 * 2 * ASIN(SQRT(POWER(SIN((12.9715987 - rooms.latitude) * PI() / 180 / 2), 2) + COS(12.9715987 * PI() / 180) * COS(rooms.latitude * PI() …

我的get路线中有一条如下路线.如何检查请求是xhr还是正常的http请求？

我想要做的是重定向,如果它http,如果xhr它将转到下面controller和action

#if xhr
get '/search' => 'pages#search'

#if http
get '/search' => redirect("/")

我怎么能这样做routes.rb???

根据BoraMa的回答,这里是routes.rb

Rails.application.routes.draw do
  require 'sidekiq/web'
  mount Sidekiq::Web => '/sidekiq'

  devise_for :users,
             :path => '',
             :path_names => {:edit => 'profile'},
             :controllers => {:registrations => 'registrations'}
  resource :pages, only: [:edit] do
    collection do
      patch 'update_password'
    end
  end

  resources :conversations, only: [:create, :index] do
    resources :messages, only: [:create, :index]
  end

  resources :notifications do
    collection do
      post :mark_as_read …

嗨,我有一个约150mb的统一游戏.我需要将其上传到谷歌Playstore.任何人都知道有任何解决方法吗？
