Ruby on rails ROR脚手架破坏重定向到

实际上，我构建了一个参考用户设计和产品的“报价”框架。我可以在特定产品页面上添加报价。然而，我意识到，当我试图删除一个报价时，它在默认情况下会重定向到products_url。如何将其重定向回特定的产品页面？当我创建注释时，它会将_重定向到特定的产品页面。删除不这样做。 我试过使用

原始代码

class OffersController < ApplicationController
before_action :set_offer, only: [:show, :edit, :update, :destroy]

def index
 @offers = Offer.all
 end

def show
end

def new
 @offer = Offer.new
 end

 # GET /offers/1/edit
 def edit
 end

 # POST /offers
 # POST /offers.json
 def create
@product = Product.find(params[:product_id])
@offer = @product.offers.new(offer_params)
@offer.user = current_user

respond_to do |format|
  if @offer.save
    format.html { redirect_to @product, notice: 'Offer was successfully created.' }
    format.json { render json: @product, status: :created, location: @offer }
  else
    format.html { render action: "new" }
    format.json { render json: @offer.errors, status: :unprocessable_entity }
  end
  end
 end

 # PATCH/PUT /offers/1
 # PATCH/PUT /offers/1.json
 def update
   respond_to do |format|
     if @offer.update(offer_params)
       format.html { redirect_to @offer, notice: 'Offer was successfully updated.' }
      format.json { render :show, status: :ok, location: @offer }
     else
    format.html { render :edit }
    format.json { render json: @offer.errors, status: :unprocessable_entity }
  end
  end
  end

     # DELETE /offers/1
  # DELETE /offers/1.json
   def destroy
   @offer.destroy
    respond_to do |format|
      format.html { redirect_to product_url, notice: 'Offer was successfully destroyed.' }
      format.json { head :no_content }
    end
   end

  private
    # Use callbacks to share common setup or constraints between actions.
   def set_offer
    @offer = Offer.find(params[:id])
    end

     # Never trust parameters from the scary internet, only allow the white list through.
    def offer_params
      params.require(:offer).permit(:product_id, :priceOffer, :user_id)
   end
 end

这实际上表明了我的错误。26实际上是提供的id。它实际上应该重定向到。它向我展示了提取的源代码，如下所示

Couldn't find Product with 'id'=26
def set_product
  @product = Product.find(params[:id])
end

我不确定我是否理解了这个问题，但我认为您只需要将产品id作为附加参数传递，例如：

= link_to 'destroy', offer_path(@offer, product_id: @product.id), method: :delete

然后在你的控制器中使用

redirect_to product_path(params[:product_id])

---

在销毁方法中执行此操作

Product=@offer.Product

重定向到：产品

@您使用的产品未设置。所以我们需要在这里设置产品标识。

这就是为什么我们通过关系从offer变量中获取产品id，您在set_product中所做的只是使用params[：id]来查找产品，但是当您调用destroy时，params[：id]是指offer_id，这就是为什么您会得到RecordNotFoundError。我想你可以写这个

def set_product
  # maybe you should judge whether @product is nil or not
  @product = @offer.product
end

def set_product
  # maybe you should judge whether @product is nil or not
  @product = @offer.product
end
