设计未定义的方法“registration_path”

Question

正在开发我的应用程序并安装和卸载一些宝石，然后突然设计的东西停止工作，我不明白为什么。我不断收到以下错误：

NoMethodError in Recipes#index
undefined method `registration_path' for #<#<Class:0x00560876ed7ef0>:0x00560876f06430>

它指的是我的注册和这段代码

<%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name), validate: true) do |f| %>
                <%= devise_error_messages! %>
                <%= f.input :email, validate: true, required: true, placeholder: "Email", label: false %>
                <% if @minimum_password_length %>
                  <em>(<%= @minimum_password_length %> characters minimum)</em>
                <% end %>
                <%= f.input :password, autocomplete: "off", required: true, placeholder: "Password", label: false %>
                <%= f.input :password_confirmation, autocomplete: "off", required: true, placeholder: "Confirm Password", label: false %>
                <%= f.input :firstname, required: true, placeholder: "First Name", label: false %>
                <%= f.input :lastname, required: true, placeholder: "Last Name", label: false %>
                <%= f.input :displayname, validate: true, placeholder: "Display Name", label: false %>
                <div class="recaptcha">
                  <%= recaptcha_tags %>
                </div>
                <%= f.button :submit, "Sign up", class: 'btn btn-primary' %>
              <% end %>

在我的routes.rb中我有这个：

Rails.application.routes.draw do
  devise_for :users, controllers: { registrations: 'registrations', omniauth_callbacks: "callbacks" }

这是注册控制器：

class RegistrationsController < Devise::RegistrationsController

    def sign_up_params
        params.require(:user).permit(:firstname, :lastname, :displayname, 
                                     :email, :password, :password_confirmation)
    end

    def account_update_params
        params.require(:user).permit(:firstname, :lastname, :displayname,
                                     :email, :password, :password_confirmation)
    end

    def create
        if !verify_recaptcha
            flash.delete :recaptcha_error
            build_resource(sign_up_params)
            resource.valid?
            resource.errors.add(:base, "There was an error with the recaptcha code below. Please re-enter the code.")
            clean_up_passwords(resource)
            respond_with_navigational(resource) {render :new}
        else
            flash.delete :recaptcha_error
            super
        end
    end

    def after_inactive_sign_up_path_for(resource)
        '/pages/confirm_email'
    end
end

我在用户模型和控制器中拥有标准的设计内容，它们没有任何变化，但它停止工作。不知道如何解决这个问题

编辑：rake 路由显示由于某种原因注册路径不在那里：

好吧，这个错误让我感到困惑。我正在使用 docker-compose 进行开发，并重建了容器和图像。删除所有内容并重新开始。设备的注册设置中的某些内容被搞乱了，不知道在哪里查看它是否正确。因此，当我转到：localhost:8000/users/sign_in一切正常，并且转到设备登录页面时...但是当我转到它时localhost:8000/users/sign_up，它说Couldn't find User with 'id'=sign_up. 就像 devise_for ：用户在注册时被忽略，并且不确定在哪里寻找该原因，这都是宝石内部的......我认为

因此，经过几个小时的挖掘我的代码，与我的旧代码进行比较并谷歌搜索我能想到的设计和注册的每种组合。我偶然发现了这个问题，这很愚蠢......在编辑我的 User.rb 模型时，我不小心从设计模块中删除了 :registable 。这就是为什么它没有生成注册路由。所以修复了我的代码行：

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable,  :confirmable, 
       :recoverable, :rememberable, :trackable, :validatable,
       :omniauthable, omniauth_providers: [:google_oauth2, :facebook]

对此：

class User < ApplicationRecord
  # Include default devise modules. Others available are:
  # :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable, :confirmable, 
       :recoverable, :rememberable, :trackable, :validatable,
       :omniauthable, omniauth_providers: [:google_oauth2, :facebook]

不确定它在哪里或如何被删除，但它确实被删除了，因为它位于块的中间，当我查看我的代码时没有注意到
