我有report_controller，其中有两个对象@report和@reporte，我想将两个对象保存在数据库中。当验证失败时，我想要以渲染的形式填充字段。验证失败后填充表单
我不能只用@report = ReportMain.new(params[:report_main])，因为我有两个对象，只有一个params对象。
我使用exportnew动作来显示表单，并用encreate来保存这个表单。
有一些简单的方法来填充表格？
ReportController：
class ReportController < ApplicationController
before_filter :authenticate_user!
before_filter :load
layout "application"
def load
@company = Company.find_by_id(current_user.company_id)
@date = Date.today
@report = ReportMain.new
@reporte = ReportE.new
end
def index
list
render("list")
end
def list
@reports = ReportMain.all
end
def exportnew
render("ennew")
end
def encreate
@report = ReportMain.new
@reporte = ReportE.new
@reportparam = params[:report_main]
@report.waste_id = params[:waste][:code]
@report.warehouse_id = Warehouse.find_by_user_id(current_user.id).id
@report.user_id = current_user.id
@report.company_id = current_user.company_id
@report.amount = @reportparam[:amount]
@report.isimport = false
@report.isfinished = false
@report.reportnumber = ReportMain.where(:company_id => current_user.company_id).count.to_i+1
if @report.save
@reporte.report_main_id = @report.id
else
@report_main = @report
render("etnew")
return
end
@reporte.vrstaotpada = params[:vrstaotpada]
@reporte.nacinpakovanja = params[:nacinpakovanja]
@reporte.ispitivanjebroj = @reportparam[:ispitivanjebroj]
@reporte.datumispitivanja = @reportparam[:datumispitivanja]
@reporte.q_pripadnost = @reportparam[:q_pripadnost]
@reporte.datumpredaje = @date
if @reporte.save
redirect_to(:action => 'show', :id => @reporte.id)
flash[:notice] = "Izveštaj je uspešno kreiran."
else
@report_main = @report
render("etnew")
end
end
def show
@report = ReportMain.find(params[:id])
@warehouse = @report.warehouse.name
end
end
查看开头（这是巨大的HTML）：
<%= form_for(:report_main, :url => {:action => 'encreate'}) do |f| %>
