活动记录的未定义方法

Question

创建新作业时，我收到有关未定义方法<fragment xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/map" xmlns:map="http://schemas.android.com/apk/res-auto" android:layout_weight="1" android:layout_width="match_parent" android:layout_height="match_parent" class="com.google.android.gms.maps.SupportMapFragment" /> 的错误。我将发布我的代码的相关部分;提前感谢您的帮助！

以下是错误消息：

  

未定义的方法`employee'for＃   ActiveRecord :: Associations :: CollectionProxy []

Employee（发生错误的地方）：

_form.html.erb

职位控制人员：

  <td colspan="4">Client-Job
          # <%= text_field_tag 'client_num', @job.opportunities.employee.office.client_num, :size => "4", :readonly => true, :tabindex => -1 %>
          -<%= f.text_field :number %></td>

员工模型：

class Job < ActiveRecord::Base
  mount_uploader :file1, AttachmentUploader
  belongs_to :cost_proposal
  has_many :opportunities
end

Schema.rb：（相关表格）

class Employee < ActiveRecord::Base
  belongs_to :office
  has_many :opportunities
  has_one :user
  delegate :company, to: :office
  validates :f_name, :l_name, presence: true

  def self.emp_id(emp_id)
    find_by(id: emp_id)
  end

  def self.emp_f_name(emp_id)
    find_by(id: emp_id).f_name

  def name_1
    [f_name, l_name].compact.join(' ')
  end

  def full_name

Answer 1

您的问题是您在ActiveRecord集合（.employee）上调用了@job.opportunities。看起来您正在尝试使用@job.opportunities.employee.office.client_num显示客户端号码，这将永远不会有效，因为您首先需要选择一个机会记录来获取其员工。您应该重新审视Job和Office模型的关联方式。
