Question

我仍然在轨道上学习ruby的基础知识，并在创建轻量级CRM时遇到错误。当我尝试为我的交易部分执行简单的创建操作时，我遇到以下错误：

ActionController::UrlGenerationError in DealsController#create

No route matches {:action=>"show", :contact_id=>"2", :controller=>"deals", :organization_id=>#<Deal id: nil, deal_name: "Amazon Deal", deal_amount: nil, contact_id: nil, created_at: nil, updated_at: nil>}, missing required keys: [:id], possible unmatched constraints: [:organization_id]

以下是我的错误截图。

Error Screenshot

我查看了StackOverflow并完成了许多Google搜索，以了解可能出现的问题，而且我似乎无法找到解决方案。

我目前正在使用 Ruby 2.4.1 和 Rails 5.1.4

这是我的控制器：

class DealsController < ApplicationController

def index
@deals = Deal.all
end

def new
@deal = Deal.new
end

def show
@deal = Deal.find(params[:id])
end

def create
@deal = Deal.new(deal_params)
@deal.save

redirect_to organization_contact_deal_url(@deal)

end

private
def deal_params
params.require(:deal).permit(:deal_name, :deal_amount)
end
end

以下是我的路线：

我希望这不是要求太多，但如果你能解释我的问题的答案，解释我做错了什么？我主要是想尽可能多地学习RoR。

谢谢！

P.S：如果您还需要其他信息，请告诉我。

修改：

添加了 new.html.erb ，其中包含我的表单：

<%= form_with scope: :deal, url: organization_contact_deals_path, 
local: true do |form| %>

<p>
<%= form.label :deal_name %>
<%= form.text_field :deal_name %>
</p>

<p>
<%= form.submit %>
</p>

<% end %>

我认为你的保存方法没有给我们真实，有些事情是错的。让我们修改像

这样的东西

def create
  @deal = Deal.new(deal_params)
  if @deal.save
    redirect_to organization_contact_deal_url(@deal)
  else
    render :new
  end
end

在新模板中

<% if @deal.errors.any? %>
  <div id="error_explanation">
    <h2><%= pluralize(@deal.errors.count, "error") %> prohibited this user from being saved:</h2>

    <ul>
      <% @deal.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
    </ul>
  </div>
<% end %>

ActionController :: UrlGenerationError-缺少必需的键：[：id]，可能是不匹配的约束
