rails 会无缘无故地自动改变路线

Question

我的 signup_path 中有以下注册表单，映射到 users#new

在我的 new.html.erb 中

            <%= form_for(@user) do |f|%>

                    <!---handles the error messages within the form. -->
                    <%= render "shared/error_messages"%>

                    <%= f.label :name%>
                    <%= f.text_field :name, class: 'form-control'%></br>

                    <%= f.label :email%>
                    <%= f.text_field :email, class: 'form-control'%></br>

                    <%= f.label :password%>
                    <%= f.password_field :password, class: 'form-control'%></br>

                    <%= f.label :password_confirmation, "Confirmation"%>
                    <%= f.password_field :password_confirmation, class: 'form-control' %></br>

                    <%= f.submit "Create My Account!", class:"btn btn-theme btn-block"%>

                <%end%>

在我的 routes.rb 中

get "signup" => "users#new"

现在我可以在 localhost:3000/signup 成功注册新用户，非常理想。但是，每当我尝试通过将部分或全部字段留空来测试表单时，它会将我重定向到 localhost:3000/users。我想我的控制器可能有问题，但我找不到任何奇怪的地方

user_controller.rb

class UsersController < ApplicationController
    # before accessing the only and edit RESTful thing, go to logged_in_user first. 
    before_action :logged_in_user, only: [:edit, :update, :index, :destroy]
    before_action :correct_user, only: [:edit, :update]
    before_action :admin_user, only: [:destroy]


    def index
        @users = User.all
    end

    def new
        # create a new user!
        @user = User.new
    end

    def show
        # declare a user variable, assign it to the current user
        @user = User.find(params[:id])
    end

    def create
        @user = User.new(user_params)
        if @user.save
            #before we watned to log the user in after they create their account, now we want them to activate their emails

            #log_in @user
            #flash[:success] = "Welcome!"
            #redirect_to @user

            @user.send_activation_email
            flash[:info] = "Please check your email to activate your account."
            redirect_to login_url
        else
            render "new"
        end
    end

我在这里做错了什么？为什么路线变了？我尝试 redirect_to signup_path 反对 render "new"，但如果我这样做，错误消息就会消失，这是我不想要的。

现在您的登录表单发布到/users，所以当您render "new" 显示的网址是正确的。如果你想改变这种行为，你可以将post "signup" => "users#create"添加到你的路由中，这样你就可以将表单发布到/signup，当你通过create操作render "new"时，它会显示你想要的url。
