将嵌套参数从重定向中的创建传递到嵌套控制器的显示

Question

我的架构如下：

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 objects 都由 create 方法创建得很好。但是在保存这些 objects 时，我试图重定向到由 Companies#create 创建的报价的 Quotes#show 但我无法将 quote_id 转到 Quotes#show。

你能帮我理解如何获得正确的参数以成功重定向吗？谢谢。

companies.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

错误信息

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

我看不出如何获得从 Companies#create 到 Quotes#show 的 quote_id 路线。当我运行重定向时； redirect_to company_quote_url(company_params) 错误显示 header 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]

我玩过但失败了；

(参数[:公司][:quote_attributes[:id]])
(@company.quote.id)

但我似乎无法正确处理，请有人帮忙。谢谢

由于 company has_many quotes，您应该跟踪该公司的最新报价 并重定向到引用的显示视图。

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

另外你应该像下面那样调整你的 quotes#show 否则它会出错。

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

将嵌套参数从重定向中的创建传递到嵌套控制器的显示
