我使用Wicked在我的 rails 4 应用程序中构建了一个向导。我专门遵循了本指南，唯一的区别是我使用嵌套资源执行此操作。我的控制器操作遇到了困难，这些操作应该使用其 ID 来查找表单正在构建的对象。

应用程序的当前流程是用户单击创建对象的按钮并被重定向到向导的第一步，该向导在一系列步骤中更新对象。问题是我没有通过参数传递对象的 ID，因为我在 ID 字段中传递了向导的步骤。

创建对象的按钮

<%= link_to business_loan_application_path(@user), method: :post, :class => "btn btn-success" do %><% end
%>

贷款申请控制器

    def create
      @user = current_user
      @loanapplication = @user.loan_applications.new
      @loanapplication.save(validate: false)
      redirect_to business_loan_application_wizard_path(@user.id,LoanApplication.form_steps.first)
    end

我需要以某种方式将 :loan_application_id 传递给 business_loan_application_wizard_path 参数。

错误

Couldn't find LoanApplication without an ID

LoanApplication 通过 has_many 关系属于_to 业务。

{"business_id"=>"55", "id"=>"business_details"}

business_details 是向导中的第一步。这些是我第一次通过带有放置请求的按钮创建对象时传递的参数。

向导控制器

class WizardController < ApplicationController
  include Wicked::Wizard
  before_filter :authenticate_user!
  before_filter :require_business

  steps *LoanApplication.form_steps

  def show
    @business = current_user
    @loanapplication = LoanApplication.find(params[:loan_application_id])
    render_wizard
  end

  def update
    @business = current_user
    @loanapplication = @business.loan_applications.last
    @loanapplication.update_attributes(loan_application_params(step))
    render_wizard @loanapplication
  end
end

这个问题的讨论有助于解决这个问题。

改变了

resources :wizard

至

scope "loan_application/:loan_application_id" do
  resources :wizard
end

在我的 routes.rb 文件中。

我的向导控制器现在如下：

def show
  @business = current_user
  @loanapplication = LoanApplication.find(params[:loan_application_id])
  render_wizard
end

def update
  @business = current_user
  @loanapplication = LoanApplication.find(params[:loan_application_id])
  @loanapplication.update_attributes(loan_application_params(step))
  render_wizard @loanapplication
end

最后，贷款申请控制器重定向链接已更改：

def create
  @user = current_user
  @loanapplication = @user.loan_applications.new
  @loanapplication.save(validate: false)
  redirect_to business_loan_application_wizard_path(@user.id, LoanApplication.form_steps.first, :loan_application_id => @loanapplication.id) 
end
