将嵌套参数从创建重定向传递到嵌套控制器的显示

Question

我有一个类似的架构：

• 公司属于用户（设计）
• 报价属于公司
• 员工属于公司

我有一个 simple_form_for 使用 cocoon 从 Company 控制器中的 create 操作创建 Company & Quote & Employees，所有对象都通过 create 方法创建得很好。但是在这些对象的 .save 上，我试图重定向到 Companies#create 创建的报价的 Quotes#show，但我无法将 quote_id 转移到 Quotes#show。

您能帮我了解如何获得正确的参数以成功重定向吗？谢谢。

公司.rb

class CompaniesController < ApplicationController
    before_action :authenticate_user!, only: [ :new, :create, :edit, :update, :destroy ]

 def new
    @company = Company.new
    @company.quotes.build
    @company.employees.build
  end

  def create
    @company = current_user.companies.new(company_params)
    if @company.save
      redirect_to company_quote_url(@company.id), notice: 'Quote request created'
    else
      render :new
    end
  end

private

  def company_params
    params.require(:company).permit(:co_name, :co_number, :postcode, :industry,
    :quotes_attributes =>       [:id, :lives_overseas, :payment_frequency],
    :employees_attributes =>    [:id, :first_name, :last_name, :email, :gender, :date_of_birth, :salary, :_destroy] )
  end
end

quotes.rb

class QuotesController < ApplicationController
  def show
    @quote = @company.quotes.find(params)
  end
end

路线

           quotes_show GET    /quotes/show(.:format)                         quotes#show
            quotes_index GET    /quotes/index(.:format)                        quotes#index

                         DELETE /users(.:format)                               devise/registrations#destroy
                         POST   /users(.:format)                               devise/registrations#create

       company_employees GET    /companies/:company_id/employees(.:format)     employees#index
        company_employee GET    /companies/:company_id/employees/:id(.:format) employees#show
               companies GET    /companies(.:format)                           companies#index

             new_company GET    /companies/new(.:format)                       companies#new
            edit_company GET    /companies/:id/edit(.:format)                  companies#edit
                 company GET    /companies/:id(.:format)                       companies#show
                         PATCH  /companies/:id(.:format)                       companies#update
                         PUT    /companies/:id(.:format)                       companies#update
                         DELETE /companies/:id(.:format)                       companies#destroy
                    root GET    /                                              companies#new

错误信息

No route matches {:action=>"show", :company_id=>65, :controller=>"quotes"} missing required keys: [:id]

我看不到如何获取从 Companies#create 到 Quotes#show 的 quote_id 路线。当我像这样运行重定向时； redirect_to company_quote_url(company_params) 错误显示标题参数是这样传递的，即这是可用的；

No route matches {:action=>"show", "co_name"=>"acme1", "co_number"=>"12345678", :controller=>"quotes",

"employees_attributes"=>{"0"=>{"first_name"=>"brian", "last_name"=>"blessed", "email"=>"brian@test.com", "gender"=>"m", "date_of_birth(1i)"=>"2001", "date_of_birth(2i)"=>"6", "date_of_birth(3i)"=>"28", "salary"=>"10000", "_destroy"=>"false"}}, "industry"=>"financial_services", "postcode"=>"al8 8ba",

"quotes_attributes"=>{"0"=>{"lives_overseas"=>"true", "payment_frequency"=>"annually"}}} missing required keys: [:company_id, :id]

我玩过不同的变体，但都失败了；

• (params[:company][:quote_attributes[:id]])
• (@company.quote.id)

但我似乎无法正确解决问题，任何人都可以帮忙。谢谢

由于公司has_many报价，您应该跟踪该公司的最新报价并重定向到报价的显示视图。

def create
  @company = current_user.companies.new(company_params)

  if @company.save
    @quote = @company.quotes.last
    redirect_to company_quote_url(@company,@quote), notice: 'Quote request created'
  else
    render :new
  end
end

last 将在created_at 的帮助下为您提供最新记录

你还应该像下面这样调整你的quotes#show，否则它会出错。

def show
  @company = Company.find(params[:company_id])
  @quote = @company.quotes.find(params[:id])
end
