購入ボタンを押して購入できるようにしたい

Question

購入機能の実装を行っています。

購入するのボタンを押したらNoMethodErrorが出てしまい、
コントローラーを確認するも、記述ミスがわかりません。

idを遷移させたいのです。

よろしくお願いします。

order コントローラーを修正
order index 修正

修正前

order.controller

省略

  def create
    @order = OrderDonation.new(order_params)

    if @order.valid?
      @order.save
      redirect_to root_path

    else
      render 'index'
    end
  end

省略

  private

  def order_params

    params.require(:order_donation).permit(:post_id, :prefecture_id, :city, :address, :buildingname, :tel, :token).merge(user_id: current_user.id, item_id: params[:item_id])
  end

省略

end

修正後

order.controller

省略

 def create
    @order = Order.create(order_params)
    if @order.valid?
      @order.save
      redirect_to root_path

    else
      render 'index'
    end
  end

省略

private

  def order_params
    params.permit(:item_id).merge(user_id:current_user.id)
　end

省略

order index 修正前

order/index

<div class='buy-btn'>
      <%# <%= f.submit "購入" ,class:"buy-red-btn" %> 
      <%= link_to '購入', order_item_path(), class: "buy-red-btn" %>
</div>

修正後

<div class='buy-btn'> 
  <%= link_to '購入', item_orders_path, method: :post, class: "buy-red-btn" %>
</div>

こちらで解決しました。
