Ruby on rails Rails创建具有嵌套属性的记录

我创建记录的RSpec测试失败

在我的收据课上

class Receipt < ActiveRecord::Base
  has_many :po_receipts, dependent: :restrict_with_exception
  has_many :jobquote_orders, through: :po_receipts
  validates_presence_of :receipt
  validates_presence_of :receipt_date
  validates_uniqueness_of :receipt, scope: :receipt_date, message: 'That receipt already exists.'

  accepts_nested_attributes_for :po_receipts
end

接收控制器.rb

def new
  @receipt = Receipt.new
end

def create
  @receipt = Receipt.new(receipt_params)
  if is_user_or_admin?
    if @receipt.save
      flash[:success] = "Receipt created."
      redirect_to receipts_path
    else
      flash[:warning] = "Invalid data."
      render :new
    end
  else
    flash[:danger] = "You are not authorized to do that."
    redirect_to receipts_path
  end
end

private

def receipt_params
  params.require(:receipt).permit(:receipt, :receipt_date, po_receipts_attributes: [:qty, :jobquote_order_id])
end

我也尝试过这个强参数

def receipt_params
  params.require(:receipt).permit(:receipt, :receipt_date, po_receipts_attributes: [])
end

def receipt_params
  params.require(:receipt).permit(:receipt, :receipt_date).tap do |t|
    t[:po_receipts_attributes] = params[:receipt][:po_receipts_attributes]
  end
end

我也尝试过这一强参数

def receipt_params
  params.require(:receipt).permit(:receipt, :receipt_date, po_receipts_attributes: [])
end

def receipt_params
  params.require(:receipt).permit(:receipt, :receipt_date).tap do |t|
    t[:po_receipts_attributes] = params[:receipt][:po_receipts_attributes]
  end
end

以下是从规范和视图传递的参数

pry(#<ReceiptsController>)> params
  => {"receipt"=>
     {"receipt"=>"3cufkz",
      "receipt_date"=>"01/09/2014",
    "po_receipts_attributes"=>
      {0=>{"qty"=>"25", "jobquote_order_id"=>"1"},
      1=>{"qty"=>"30", "jobquote_order_id"=>"2"}}},
    "controller"=>"receipts",
    "action"=>"create"}

它将保存收据，但不会通过rails服务器窗口中的accepts_nested_attributes_for:po_receipts

保存po_收据，当您创建一个具有嵌套属性的收据时。。。您通常会看到一条消息，告诉您它不接受某些属性，并将它们丢弃。您能否尝试在浏览器中创建，并查看是否有任何错误消息表明这一点，并检查它是否接受那里的属性？谢谢@TarynEast的回复。它实际上是无声地失败的。我最终根据浏览器中的视图生成的结果生成了RSpec参数。这就是为什么它让我困惑的部分原因。rspec默默地失败了。。。但在浏览器窗口中尝试，同时查看服务器日志。看看哪些参数实际上以散列形式传递，然后将它们复制/粘贴到您的问题中。然后此外，还应复制紧随其后的任何一行，该行将参数视为不允许删除，如果您的参数未通过许可/要求行，则该行将100%始终出现在日志中。
