Rails嵌套窗體屬性不保存

難以從嵌套窗體保存嵌套屬性。我可以看到參數在提交後通過表單傳遞。我有2個表格：文件和salary_reports。我檢查了日誌，並且接收插入的唯一表是salary_reports，而不是文檔。可能是什麼問題呢？

型號：

class SalaryReport < ActiveRecord::Base 

    STATUS = %w[new waiting_for_approval approved dissaproved] 

    belongs_to :user 

    has_many :documents 

    accepts_nested_attributes_for :documents 
end 


class Document < ActiveRecord::Base 

    TYPES = %w[sales valuation mileage expense] 

    belongs_to :salary_report 
end

控制器

def new 
    @salary_report = SalaryReport.new 
    @salary_report.documents.build 
    end 

    def create 
    @salary_report = SalaryReport.new(salary_report_params) 

    if @salary_report.save 
     redirect_to salary_reports_path, notice: "Lönerapporten sparades korrekt!" 
    else 
     render :new, notice: "Något gick fel när lönerapporten skulle sparas!"  
    end 

    end 

private 
    def salary_report_params 
    params.require(:salary_report).permit(:user_id, :approved_by_admin_id, :status,  :comment_from_created_by, :comment_from_admin, :total_sales_since_year_start, :date_sent,  :date_of_approval, :total_buffer, :salary_period, documents_attributes: [:id, :description, :type,  :total]) 
end

登錄提交表格後：

的看法是這樣的：

<%= form_for @salary_report, :html => { :class => "well"} do |f| %> 
    <%= f.label :salary_period %> 
    <%= f.date_select :salary_period, :as => :date, :order => [:month, :year] %> 
    <%= f.label :comment_from_created_by %> 
    <%= f.text_area :comment_from_created_by %> 
    <%= f.label :comment_from_admin %> 
    <%= f.text_area :comment_from_admin, :disabled => true %> 
    <%= fields_for :documents do |builder| %> 
     <%= render "document_fields", :f => builder %> 
    <% end %> 
    <%= link_to_add_fields "ny rad", f, :documents %>   
    <%= f.submit "Skicka till admin för godkännande", disable_with: 'Skickar....', :class => "btn btn-success" %> 

<% end %>

嘗試增加一個f。前fields_for

<%= f.fields_for :documents do |builder| %> 
    <%= render "document_fields", :f => builder %> 
<% end %>

耶！那工作。謝謝！ –

不幸的是，我現在正在收到follwing錯誤：無效的單表繼承類型：銷售不是文檔 –

的子類：type是用於引用其他模型的名稱的保留屬性。嘗試將其命名爲：kind。 – Scymex

嘗試

private 
     def salary_report_params 
     params.require(:salary_report).permit(:user_id, :approved_by_admin_id, :status,  :comment_from_created_by, :comment_from_admin, :total_sales_since_year_start, :date_sent,  :date_of_approval, :total_buffer, :salary_period, documents_attributes: [:id, :description, :type,  :total]) 
    end

您必須通過「ID」在document_attributes ......在這個時候沒有很好的記錄...

乾杯

我添加此添加：id到documents_attributes（在我的問題中編輯），但這似乎沒有幫助。如果有幫助，也會添加有問題的日誌。 –

好更改列名的作品，但通常解決這個正確的方法是通過禁用該模型的inheritance_column功能。使用Rails你also.If要使用的名稱必須使用保留關鍵字特權：類型然後就在你的model.rb文件

self.inheritance_column = nil

希望它可以幫助
