Rubyonrails Ruby on Rails form_with 不显示错误，卡在服务器端

我肯定我错过了一些非常简单的东西，但我很难理解.我有一个用户注册表单，它可以正确地识别服务器上注册过程中的错误，但它没有将该信息传递回视图以呈现表单上方的错误.

controllers/registrations_controller.rb个

class RegistrationsController < ApplicationController
    def new
        @user = User.new
    end

    def create
        @user = User.new(user_params)
        if @user.save
            redirect_to root_path, notice: "Successfully signed up!"
        else
            puts 'ERRORS BELOW:'
            puts @user.errors.full_messages
            render :new
        end
    end

    private

    def user_params
        params.require(:user).permit(:email, :password, :password_confirmation)
    end
end

views/registrations/new.html.erb个

<%= form_with model: @user, url: signup_path do |f| %>
    <% if @user.errors.any? %>
        <div class="alert alert-danger">
            <% @user.errors.full_messages.each do |message| %>
                <div><%= message %></div>
            <% end %>
        </div>
    <% end %>

    <div class='mb-3'>
        <%= f.label :email %>
        <%= f.text_field :email, class:'form-control', placeholder: 'john@test.com' %>
    </div>
    <div class='mb-3'>
        <%= f.label :password %>
        <%= f.password_field :password, class:'form-control', placeholder: 'password' %>
    </div>
    <div class='mb-3'>
        <%= f.label :password_confirmation %>
        <%= f.password_field :password_confirmation, class:'form-control', placeholder: 'password' %>
    </div>

    <div class="mb-3">
        <%= f.submit 'Get Started', class: 'btn btn-primary' %>
    </div>
<% end %>

routes.rb个

Rails.application.routes.draw do
    root to:'main#index'

    get "signup", to: 'registrations#new'
    post "signup", to: 'registrations#create'

    get "about-us", to: 'about#index', as: :about
end

View from my console showing the errors getting printed out serverside个

我试着把它们作为闪光灯通知，甚至在@user.save失败后也没有渲染:new，不知道还能try 什么.我在这里找到的许多类似问题的解决方案似乎都是通过将if/else块放在create函数中来解决的，但我已经把它放进go 了.不知道我错过了什么.

我还应该补充的是，当我输入正确的邮箱和匹配的密码时，我可以创建一个User，当我没有通过这两个判断时，它不会创建用户，只是不会将这些错误传递回客户端
