我只想指出:我的互联网连接很糟糕.所以我开始推新图像,场景是这样的:

同时推送所有这些图层只是简单地杀死我的互联网连接,不允许我导航和定位器抵制自己,因为许多这些图层都上传了错误并一次又一次地重新启动.
有没有办法在时间上传单个图层？(顺便说一句,不,改变我的ISP或我糟糕的路由器不是一个选项)

我是有一些问题,宙斯+ rspec的和我找到了解决办法说,我一定要删除require 'rspec/autorun'的spec_helper.rb.

这很有效,但我想知道它的用途是rspec/autorun什么？spec_helper.rb默认情况下它会出现,但无论有没有,规格都可以使用.

我是新手用Rails 4操纵angularjs,它只提供api.我尝试创建一个简单的角度服务来上传文件.但我使用Paperclip来管理文件,我有一些问题.

首先,我不明白如何正确收集输入文件.我已经看到很多插件或胖指令来做到这一点.但我想要一个简单的指令收集我的文件并放入我的ng模型.

最后我想知道在Base64中编码我的文件是否更有效？

我的Rails控制器

class Api::EmployeesController < Api::BaseController
  def create
    employee = Employee.create(employee_params)
    if employee.save
      render json: employee
    else
     render :json => { :errors => employee.errors.full_messages }, :status => 406
     end
  end

  def employee_params
    params.require(:employee).permit(:first_name,:mobile_phone,:file)
  end
end

我的Angularjs服务

angular.module('test').factory 'Employee', ($resource, $http) ->
 class Employee
  constructor: (errorHandler) ->
  @service = $resource('/api/employees/:id',
  {id: '@id'},
  {update: {method: 'PATCH'}})
  @errorHandler = errorHandler

  create: (attrs, $scope) ->
    new @service(employee: attrs).$save ((employee) ->
      $scope.employees.push(employee)
      $scope.success = true
      $timeout (->
        $scope.success = false
      ), 3000 …

我遇到了与此问题相反的问题.该Gemfile有:

source 'https://rubygems.org'
ruby '2.3.1'

在我的Gemfile.lock文件的末尾是:

RUBY VERSION
   ruby 2.3.1p112

 BUNDLED WITH
    1.12.4

但是当我运行时bundle install总是删除,RUBY VERSION无论我使用的是开发团队的版本.即使我使用的是比用于生成原始Gemfile.lock文件的更新的Bundler版本:

$ bundle -v
Bundler version 1.12.5
$ ruby -v
ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-linux]

任何想法我怎么能阻止这个？

我的Guardfilerails项目中有一个文件,但只是以纯文本显示,因此每次打开时都必须分配ruby语法才能正确显示它.
我不能使用Open all with current extension as...,因为它不具有扩展名,但我想我可以分配一个特定的语法文件没有扩展名的文件,因为喜欢Gemfile,Capfile还是Rakefile能正确显示.我怎样才能做到这一点？

当我尝试将网站更新到 Ruby 3.0.0 时，出现以下错误：

ArgumentError（参数数量错误（给定 2，预期 1））

 % rails console

irb(main):001:0> puts RUBY_VERSION

以下是与 Ruby 2.7.2 相同的命令

一个基本的问题，但是我在项目页面或Wiki中找不到清晰的内容。我有以下代码：

field = "secre"
Position.search( {:description_cont => field, :code_cont => field}).result(:distinct => true).to_sql
 => "SELECT DISTINCT `positions`.* FROM `positions`  WHERE ((`positions`.`description` LIKE '%secre%' AND `positions`.`code` LIKE 0))"

但是我的查询应该是这样的：

 => "SELECT DISTINCT `positions`.* FROM `positions`  WHERE ((`positions`.`description` LIKE '%secre%' OR `positions`.`code` LIKE 0))"

任何帮助，将不胜感激。提前致谢

我使用rake 10.0.4并且我已经升级到10.1.0,但现在当我部署到我的登台服务器时它会抛出我:

如何解决这个问题？

I am new to Ruby on Rails and maybe this is a very trivial issue, but I searched online for a solution and all of them are at least 2-3 years old and they described the same thing. All the tutorials and videos I watched, said to create a new app with webpack for React, using:

rails new app_name --webpack=react -d=postgresql -T\n

Everybody said, that this command will create a pack folder under my app/javascript folder like this: …
