Rails 4.0 和 Devise 3.0

Question

我已经查看我的代码有一段时间了，但无法确定 Devise 的错误在哪里。我在 Sign Up 视图中添加了一些额外的行，并按照设计自述文件中的描述更改了所有内容，但是没有显示其他字段，只有通常的 Email、Password 和 Confirm Password 字段显示。我的用户被称为 Knockers，以防有人想知道！

这是我的浏览页面（registrations\new.html.erb）：

<h2>Sign up</h2>

<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>

   <div><%= f.text_field :first_name %></div>

   <div><%= f.text_field :last_name %></div>

   <div><%= f.text_field :username %></div>

   <div><%= f.text_field :gender %></div>

   <div><%= f.date_field :dob %></div>

   <div><%= f.label :email %><br />
   <%= f.email_field :email, :autofocus => true %></div>

   <div><%= f.label :password %><br />
   <%= f.password_field :password %></div>

   <div><%= f.label :password_confirmation %><br />
   <%= f.password_field :password_confirmation %></div>

   <div><%= f.submit "Sign up" %></div>
<% end %>

<% if knocker_signed_in? %>
   Signed in as <%= current_knocker.name %>. Not you?
   <%= link_to "Sign out", destroy_knocker_session_path,:method => :delete %>
<% else %>
   <%= link_to "Sign up", new_knocker_registration_path %> or
   <%= link_to "Sign in", new_knocker_session_path %>
   <%= link_to "Sign in with Facebook", knocker_omniauth_authorize_path(:facebook) %>
<% end %>

<% if knocker_signed_in? %>
   Signed in as <%= current_knocker.name %>. Not you?
   <%= link_to "Sign out", destroy_knocker_session_path,:method => :delete %>
<% else %>
   <%= link_to "Sign up", new_knocker_registration_path %> or
   <%= link_to "Sign in", new_knocker_session_path %>
   <%= link_to "Sign in with Twitter", knocker_omniauth_authorize_path(:twitter) %>
<% end %>

<% if knocker_signed_in? %>
   Signed in as <%= current_knocker.name %>. Not you?
   <%= link_to "Sign out", destroy_knocker_session_path,:method => :delete %>
<% else %>
   <%= link_to "Sign up", new_knocker_registration_path %> or
   <%= link_to "Sign in", new_knocker_session_path %>
   <%= link_to "Sign in with Google", knocker_omniauth_authorize_path(:google_oauth2) %>
<% end %>

<%= render "knockers/shared/links" %>

我的模型页面 (\knocker.rb)

我的数据库迁移：

 class DeviseCreateKnockers < ActiveRecord::Migration
   def change
     create_table(:knockers) do |t|
       t.string :first_name,         :null => false
       t.string :last_name,          :null => false
       t.string :username,           :null => false
       t.string :town
       t.string :postcode
       t.float :latitude                       
       t.float :longitude           
       t.date :dob,                  :null => false
       t.text :about
       t.string :gender,             :null => false
       t.string :nationality

       ## Database authenticatable
       t.string :email,              :null => false, :default => ""
       t.string :encrypted_password, :null => false, :default => ""

       ## Omniauth data
       t.string :provider
       t.string :uid

       ## Recoverable
       t.string   :reset_password_token
       t.datetime :reset_password_sent_at

       ## Rememberable
       t.datetime :remember_created_at

       ## Trackable
       t.integer  :sign_in_count, :default => 0, :null => false
       t.datetime :current_sign_in_at
       t.datetime :last_sign_in_at
       t.string   :current_sign_in_ip
       t.string   :last_sign_in_ip

       ## Confirmable
       # t.string   :confirmation_token
       # t.datetime :confirmed_at
       # t.datetime :confirmation_sent_at
       # t.string   :unconfirmed_email # Only if using reconfirmable

       ## Lockable
       t.integer  :failed_attempts, :default => 0, :null => false # Only if lock strategy is :failed_attempts
       t.string   :unlock_token # Only if unlock strategy is :email or :both
       # t.datetime :locked_at


       t.timestamps
     end

     add_index :knockers, :email,                :unique => true
     add_index :knockers, :reset_password_token, :unique => true
     add_index :knockers, :username,              :unique => true
     add_index :knockers, :latitude
     add_index :knockers, :longitude
     add_index :knockers, :dob
     # add_index :knockers, :confirmation_token,   :unique => true
     # add_index :knockers, :unlock_token,         :unique => true
   end
 end

最后是我的应用程序控制器：

 class ApplicationController < ActionController::Base
   # Prevent CSRF attacks by raising an exception.
   # For APIs, you may want to use :null_session instead.
   protect_from_forgery with: :exception
   before_filter :configure_permitted_parameters, if: :devise_controller?

   protected

   def configure_permitted_parameters
     devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :first_name, :last_name, :gender, :dob, :email, :password, :password_confirmation) }
   end
 end

任何帮助将不胜感激。我在这里查看了一些问题，但其中大多数似乎只是获取了错误的字段类型......看不到这里的问题是什么，除非它与实施不当的 OAuth 问题有关。

Answer 1

将application_name/app/views目录下的knockers文件夹重命名为devise。

在生成视图时，您错误地将它们生成为rails generate devise:views knockers 而不是rails generate devise:views。

如果您有多个设计模型并且需要不同的视图（自定义），您可以使用rails generate devise:views knockers 生成视图。
