Question

我需要在提交表单时redirect_to用户/索引页面，但浏览器显示相同的页面，删除所有表单并显示这个奇怪的地址：

http://localhost:3000/signup?utf8=%E2%9C%93&authenticity_token=aKZ7qWC9ZUMyFXYNxvVfL%2F4BpTSB0sZtpm1a4AWNvWE%3D&user%5Bsecondname%5D=&user%5Bfirstname%5D=&user%5Bpatronymic%5D=&user%5Bdateofbirth%283i%29%5D=&user%5Bdateofbirth%282i%29%5D=&user%5Bdateofbirth%281i%29%5D=&user%5Blogin%5D=&user%5Bemail%5D=&user%5Bpassword%5D=&user%5Bpassword_confirmation%5D=&commit=%D0%97%D0%B0%D1%80%D0%B5%D0%B3%D0%B8%D1%81%D1%82%D1%80%D0%B8%D1%80%D0%BE%D0%B2%D0%B0%D1%82%D1%8C%D1%81%D1%8F

当我用空表单提交它时没有相同的事情发生（没有错误列表）虽然RSpec说所有测试都通过......

我的USERS_CONTROLLER.RB：

class UsersController < ApplicationController

  def new
    @user = User.new
  end

  def create
    @user = User.new(params[:user])
    if @user.save
      redirect_to action: :index
    else
      render 'new'
    end
  end

  def index
    @users = User.all
  end

  def destroy
    @user = User.find(params[:id])
    @user.destroy

    redirect_to action: :index
  end
end

哇！事实证明问题出在标记<form>中。没有它一切都很好，但为什么呢？ Bootstrap说：将.form-horizontal添加到表单

Answer 1

您的redirect_to错误，应该重定向到路径（网址）。

尝试：

redirect_to users_path

Answer 2

您可以直接重定向到某个操作，也可以使用

redirect_to :action => :index

Answer 3

问题出在您使用的<form>的两个标签中。另外，建议在form_for标记之外或之前呈现错误消息。对于添加类或任何html属性，可以添加到form_for或类似的标签，例如:attr_name => "value"，因此如果您想添加class以假设myclass，您可以像:class => "myclass"那样{1}}

redirect_to重定向同一页面，测试不会失败
