Question

我正在控制器中从新方法发送一个表单，但不是通过创建操作，而是返回到新操作。关于这一点有无数的帖子，我做了一些研究但没有结束工作。我不确定是不是因为我的新网址不仅仅是'/ purchase / new'，而是“/purchase/new#{trip.id}”。我不认为这应该有所作为。

应用/控制器/ purchases_controller.rb

class PurchasesController < ApplicationController


  def new
    trip = Trip.find(params[:trip_id])

    @purchase = trip.purchases.build

    if @purchase.trip_id == 1
        render 'paris'
    elsif @purchase.trip_id == 2
        render 'ny'
    else
        render 'tokyo'
    end
  end

 def create
    @purchase   = Purchase.new(purchase_params)
    if @purchase.save
        redirect_to '/', :notice => "Enjoy your trip"
    else
        redirect_to '/'
    end
 end    

def show
end



private

def purchase_params
    params.require(:purchase).permit(:email)
end
end

应用/视图/布局/ _form.html.erb

    <br>

 <% if @purchase.errors.any? %>
    <div class="error_messages">
        <ul>
            <%= @purchase.errors.full_messages.each do |error| %>

配置/路由 资源：购买

Answer 1

<%=form_for @purchase, :url=>{:action=> "create", :controller=>"purchases"}, :method=>"post" do |f| %>

#Your form html code will here

<%end%>

Answer 2

事实证明，当我渲染表单时，我在页面中呈现它 <form>标记。 Rails不喜欢那样。只要我将<form>更改为<div>，提交请求便会进入后期路线。

发送到新操作而不是发布
