24小时后,我试图找到我的应用程序的问题.我终于找到了问题.

我跑了

rake assets:precompile RAILS_ENV=production

我一直在收到这个错误.

/Users/vezu/.rvm/rubies/ruby-1.9.3-p194/bin/ruby /Users/vezu/.rvm/gems/ruby-1.9.3-p194@global/bin/rake assets:precompile:all RAILS_ENV=production RAILS_GROUPS=assets

我的database.yml文件看起来像这样

我和Heroku以及Carrierwave Gem有点失落.我已经阅读了WIKI,阅读我并搜索网络,我承认,我需要帮助.一切都在当地很好,但Heroku粉碎了应用程序.

/// HEROKU LOGS的错误消息

end

当我将存储更改为文件而不是雾时,我不会得到错误.我是否正在跳过或丢失任何其他雾设置.任何帮助非常感谢.我是否需要创建具有雾设置的单独文档？

我刚刚添加了gem'carrierwave',它正在破坏护栏4.0.我添加了rubyzip gem,但它无法解决问题.我无法再运行任何测试,我无法弄清楚如何解决这个问题.

学习如何使用Rspec 3.我对匹配器有疑问.我关注的教程基于Rspec 2.

describe Team do

  it "has a name" do
    #Team.new("Random name").should respond_to :name
    expect { Team.new("Random name") }.to be(:name)
  end


  it "has a list of players" do
    #Team.new("Random name").players.should be_kind_of Array
    expect { Team.new("Random name").players }.to be_kind_of(Array)
  end

end

为什么代码导致错误,而我注释掉了通过折旧警告.

错误

Failures:

  1) Team has a name
     Failure/Error: expect { Team.new("Random name") }.to be(:name)
       You must pass an argument rather than a block to use the provided matcher (equal :name), or the matcher must implement `supports_block_expectations?`.

使用devise gem和获取JWT令牌时遇到问题devise-jwt gem。这就是我的确认结果。

devise.rb

  Devise.setup do |config|

    config.jwt do |jwt|
      jwt.secret =  SECRETS.devise_jwt_secret_key
      jwt.dispatch_requests = [ ['POST', %r{^/authentication_tokens/create$}] ]
    end
end 

user.rb

class User < ApplicationRecord

    devise :database_authenticatable, :registerable,
           :recoverable, :rememberable, :trackable, :validatable,
           :jwt_authenticatable, jwt_revocation_strategy: Devise::JWT::RevocationStrategies::Null

  end

authentication_tokens_controller.rb

class Api::V1::AuthenticationTokensController < Devise::SessionsController
  include Devise::Controllers::Helpers
  skip_before_action :verify_authenticity_token 

  prepend_before_action :require_no_authentication, only: [:create]

我正在尝试设置JPlayer插件和Shoutcast.根据他们的网站,这是可能的.

如何让jPlayer播放SHOUTCast流？您需要将媒体设置为流URL.例如,SHOUTcast服务器:http://mp3-vr-128.as34763.net/ MP3流URL:http: //mp3-vr-128.as34763.net/; stream/1

我试过这样做

<script type="text/javascript">
//<![CDATA[
$(document).ready(function(){

    $("#jquery_jplayer_1").jPlayer({
        ready: function (event) {
            $(this).jPlayer("setMedia", {
                m4a:"http://77.68.106.224:8018;stream/1",
                oga:"http://77.68.106.224:8018"
            }).jPlayer("play");
        },


        swfPath: "js",
        supplied: "m4a, oga, mp3", 
        wmode: "window"
    });
});
//]]>
</script>

我的设置没有任何输出.是否有人使用JPlayer进行shoutcast Stream,或者任何人都可以建议不需要php的播放器.

我在理解错误日志时遇到问题.我正在使用Active Admin,一切都在我的本地服务器上运行良好但是当我推送到Heroku时我无法登录或使用活动管理员.关于问题是什么,我有点困惑.我妻子的前端工作,但当我第一次尝试登录时,我收到此错误.

我跑了

 heroku run rake db:migrate

application.rb中

   config.assets.initialize_on_precompile = false

的routes.rb

 break if ARGV.join.include? 'assets:precompile'

尝试设置SSL以在mydomain.com上运行.遵循Heroku文档,我已经管理好了SSL工作在https://secure.mydomain.com.但是当我添加SSL时由heroku创建的实际端点仍在说

**Heroku | No such app**

There is no app configured at that hostname.
Perhaps the app owner has renamed it, or you mistyped the URL.

关于如何让tokyo-2121.herokussl.com指向我在Heroku上的实际应用程序,我有点困惑.

我正在研究我的第一个Rails应用程序.我有点卡住了时间.我正在研究食谱应用程序.我需要添加两个字段.

• 准备时间
• 烹饪时间

在这两个中,我想添加两个字段来计算准备餐点所需的总时间.

我接近它错误的方式,没有逻辑:(.基本上我有两个字段,我使用f.select选择预定义的时间.但我的方法的问题是,当添加两个,它忽略了格里高利格式例如40分钟+ 50分钟将变为90分钟而不是1小时30分钟.

我很感激社区的帮助.

使用法语在rails应用程序上工作,但每当我在flash消息中包含重音时,它就会破坏站点.

例如

format.html {redirect_to @message.annonce, notice:"Votre message a été envoyé"}
format.html {redirect_to @message.annonce, notice:"Votre email n'a pas pu être envoyer à cause d'une erreur."}

我的config/application.rb看起来像这样

 config.i18n.default_locale = :fr
 config.encoding = "utf-8"

人们如何做到这一点？

我刚刚离线创建应用程序后转移到了站点5.我有耙子的问题.当我尝试运行cd~/MYAPP /; rake db:migrate --trace RAILS_ENV ='production'

我收到以下错误

你已经激活了rake 0.8.7,但你的Gemfile需要rake 0.9.2.考虑使用bundle exec.

当我尝试在下面的数据上使用ES6 时,我很难理解为什么会出现错误.find.我正在尝试获取身份证号码为3的记录.

{
 {id:10,title:'Dairy & Eggs'}
 {id:7,title:'Laundry & Househo,}
 {id:9,title:'Bakery'}
 {id:8,title:'Fresh Food'}
 {id:4,title:'Frozen Food'}
 {id:6,title:'Health & Beauty'}
 {id:3,title:'Food Cupboard'}
 {id:5,title:'Drinks'}
 {id:2,title:'Chilled Food'}
}

我试过了

 const category = categories.find(function (category) { return category.id === 3; } 

 console.log(category)

和

const category = categories.filter(category => category.id === 3) 
console.log(category)

任何帮助表示赞赏.

我有一个优惠券模型,我试图计算你从原始交易中节省多少.

Coupons.rb

def original_deal
  original_price
end

def our_deal
  deal_price
end

def percentage_off
  original_deal / our_deal * 100.ceil
end

Show.html

<%= number_to_percentage(@coupon.percentage_off, :precision => 2) %> 

优惠券信息

original_price = £100.00
deal_price = £90.00

结果.

我得到111.11%的答案.我错过了什么？
