Question

这是我的控制者：

class ReportNeedsController < ApplicationController
def index
@report_needs = nil
end
  def new
     @report_need = ReportNeed.new
  end    
  def create
     @report_need = ReportNeed.new(params[:report_need])
     @report_need.save
     redirect_to @report_need
  end
end

这是我的new.haml文件：

在视图中进行更改，如：

  %input{:type => "radio", :name => "report_need[product_type]", :id => "report_need[product_type]-1", :value => "salesforce", :checked => true}
  %br/
  %input{:type => "radio", :name => "report_need[product_type]", :id => "report_need[product_type]-2", :value => "salesforce", }

在控制器中，如果 product_type 是表格 report_needs 的字段，则无需更改操作。否则它会改变并存储起来：

  def create
     report_need = ReportNeed.new(params[:report_need])
     report_need.radio_field_name = params[:report_need][product_type]
     report_need.save
     redirect_to report_need
  end
