我有一个属于个人资料模型的工作模型.配置文件has_many工作.我有一个嵌套的模型表单,用户可以在其中添加作业.表单已成功添加作业,但编辑/更新无效.相反,当我尝试编辑作业时,它会保留旧版本的作业,但也会添加新版本.它不会用新版本替换旧版本.我该如何解决？我很确定它与编辑/更新控制器有关.

编辑控制器:

def edit
    @profile = current_user.profile
end

更新控制器:

def update
    #if current_user.profile.jobs.any?

    @profile = current_user.profile.update_attributes(profile_params)

    if current_user.profile.invalid?
        @profile = current_user.profile
        render :edit, :status => :unprocessable_entity
    else
        redirect_to profile_path(current_user.profile_name)
    end
end

问题是,更新控制器正在处理非嵌套信息,它不适用于嵌套作业.以下是强大的参数:

def profile_params
      params.require(:profile).permit(:title,
           :category, :description, :state, :zip_code, :rate, 
           jobs_attributes: [:firm, :position, :category, :description,
           :begin, :end, :_destroy])        
end

这是配置文件模型:

class Profile < ActiveRecord::Base
    belongs_to :user
    has_many :jobs
    accepts_nested_attributes_for :jobs , :reject_if => :all_blank, :allow_destroy => true
end

此外,这是我的路线,如果这将有所帮助:

resources :profiles do
   resources :jobs
end

感谢您的帮助.

我有一个 ruby​​ 应用程序，自由职业者可以在其中为雇主完成工作。工作完成后，自由职业者可以上传文件供雇主审查。我认为自由职业者应该能够上传 zip 文件，但我不希望自由职业者能够上传无效或损坏的 zip 文件。有什么办法可以阻止这种情况或检查文件是否有效。我很确定是否有方法或函数可以做到这一点，它会在 ruby​​zip 库中，但我已经浏览了他们的文档，但找不到我要找的东西。

我有一个带有单选按钮的简单表单,它从服务器中提取值并循环遍历它们以提供单选按钮:

<form ng-submit="createSubCategory(subcategory)">
    <div ng-repeat="sub_category in event_sub_categories" >
        <label class="item item-radio">
                  <input type="radio" ng-model="subcategory" ng-value="'{{sub_category}}'" >
                  <div class="radio-content">
                    <div class="item-content">
                      {{sub_category}}
                    </div>
                    <i class="radio-icon ion-checkmark"></i>
                  </div>
         </label>
    </div>
    <div class="padding">
        <button type="submit" class="button button-block button-positive">Continue</button>
    </div>
</form>

表格完美显示.但是,我按下的单选按钮似乎没有保存.这是createSubCategory方法:

$scope.createSubCategory = function(subcategory){
  console.log(subcategory);
}

日志正在显示undefined.填写表格后如何记录子类别？

我已经尝试过 Devise 的 github 上的代码。在我的应用程序控制器中，我有：

after_filter :store_location

def store_location
  # store last url - this is needed for post-login redirect to whatever the user last visited.
  if (request.fullpath != "/users/sign_in" &&
      request.fullpath != "/users/sign_up" &&
      request.fullpath != "/users/password" ) 
    session[:previous_url] = request.fullpath 
    puts 'stores location'
  end
end

def after_update_path_for(resource)
  session[:previous_url] || dashboard_path
  puts 'after update'
end

当我检查我的服务器时，会出现 store_location 方法中的 puts 语句，但 after_update_path_for 中的 puts 语句没有出现。如何让 after_update_redirect 工作？

这是设计所说的，但它不起作用：

我正在使用thumbs_up gem创建一个投票系统.我正在使用PostgreSQL.当我跑:

rails generate thumbs_up

我该如何解决？

我刚从另一台计算机上克隆了我正在处理的存储库.当我尝试通过运行'rake db:migrate'进行数据库迁移时,我收到以下错误:

AbstractController::Helpers::MissingHelperError: 
Missing helper file helpers//users/psmith/projects/clie/projectlion/app/helpers/application_helper.rb_helper.rb

我已经在这里尝试了最常见的答案:Rails:AbstractController :: Helpers :: MissingHelperError - 缺少帮助文件application_helper.rb_helper.rb

它说要在终端中执行以下操作:

cd ~
mv projects projects1
mv projects1 projects

我也尝试过:

sudo ln -s Users users

但这对我不起作用.我该怎么办？

更新:

这是我的堆栈跟踪:

我让sublime text 2命令行工具正常工作。当我下载Sublime Text 3时，我无法使用命令行工具。我在这里尝试了所有答案：在macOS中从Terminal打开Sublime Text。当我输入：

ln -s /Applications/Sublime\ Text.app/Contents/SharedSupport/bin/subl /usr/local/bin/subl  

我回来了：

ln: /usr/local/bin/subl: File exists

但不管我做什么我仍然会回来 -bash: subl: command not found

我有以下设置：

class TeamEnrollment < ApplicationRecord
    belongs_to :team
    has_many :term_enrollments, through: :team
end

上面的代码工作正常。现在我需要将 has_many 行更改为如下所示：

has_many :term_enrollments, 
   -> {where("(term_enrollments.term_start_date <= ? AND term_enrollments.term_end_date >= ?) OR (term_enrollments.term_start_date >= ? AND term_enrollments.term_end_date > ?) OR (term_enrollments.term_start_date <= ? AND term_enrollments.term_end_date >= ?)", self.start_date, self.start_date, self.start_date, self.termination_date, self.termination_date, self.termination_date)}
   , through: :team

从上面的代码中，如果我尝试这样做，我会收到以下错误TeamEnrollment.first.term_enrollments：

undefined method `start_date' for #<TermEnrollment::ActiveRecord_Relation:0x007ff706550550>

我已经where用上面的代码的第一个配置测试了该子句，它工作正常。只有在has_many子句中它才不起作用。我很确定这与在has_many through. 我试图参考 TeamEnrollment 的 start_date。我该怎么做呢？

我无法让glyphicons与bootstrap 3和rails一起使用.我已经在互联网上找到了灵感,没有找到任何帮助.在我的bootstrap.css文件中,我有:

@font-face {
  font-family: 'Glyphicons Halflings';

  src: url('/assets/glyphicons-halflings-regular.eot');
  src: url('/assets/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons_halflingsregular') format('svg');
}

在application.rb中,我有:

config.assets.enabled = true  
config.assets.paths << "#{Rails.root}/app/assets/fonts" 
config.assets.precompile += %w( .svg .eot .woff .ttf )

我已经尝试过跑:

rake资产:预编译RAILS_ENV =开发

在application.js我有:

//= require jquery
//= require jquery_ujs
//= require_tree .
//= require bootstrap

在application.css我有:

 *= require_self
 *= require_tree .
 *= require bootstrap
 */

我的所有字体都存储在资源/字体中

我已经看过以下内容,但没有一个有效:

Bootstrap 3 + Rails 4 - 某些Glyphicons不工作

如何将自定义字体添加到Rails应用程序？

我怎样才能解决这个问题？

我已经使用 twilio api 发送消息 3 年了，它运行得很好。从 ruby​​ 2.6 升级到 ruby​​ 3.1.3 后，Twilio 不再工作。我们使用的是 twilio-ruby 5.74.2。我们收到错误ArgumentError (wrong number of arguments (given 1, expected 0)):。我有以下代码：

def send_pin_through_twilio
        client = Twilio::REST::Client.new
        client.messages.create({
            from: ENV["twilio_phone_number"],
            to: self.phone_number,
            body: "Hello from ...! Your one-time pin is #{self.one_time_pin}."
        })
end
