Rails 3 Devise 手动更改密码

Question

我尝试在我的 Rails 应用程序中使用 devise 。但我不明白如何为用户提供更改密码的功能。我需要一个包含“旧密码”、“新密码”和“新密码确认”字段的表单。我该怎么做？

如果我在“/profile”页面上使用默认设计形式

<%= render :template => 'devise/passwords/edit', 
                        :locals => { 
                          :resource => my_user_model_variable, 
                          :resource_name => my_user_model_name } %>

在 user.rb 包含行

attr_accessible :email, :password, :password_confirmation, :remember_me

但是有 未定义的方法“devise_error_messages！”对于 #<# 然后（在注释 devise_error_messages! 行之后） # 错误未定义方法“密码”。

我尝试使用我自己的PasswordsController：

class PasswordsController < ApplicationController
  before_filter :authenticate_user!

  def edit
    @user = current_user
  end

  def update
    @user = current_user
    raise params.inspect
    if @user.update_with_password(params[:user])
      sign_in(@user, :bypass => true)
      redirect_to root_path, :notice => "Password updated!"
    else
      render :edit
    end
  end
end

并使用这个问题的建议：渲染设计编辑密码表单

将此代码插入

<%= render :template => 'passwords/edit', 
                    :locals => { 
                      :resource => current_user, 
                      :resource_name => User } %>

“/profile”页面。

passwords/edit.html.erb 包含此代码

<h2>Change your password</h2>
<%# raise resource.inspect %>
<%= form_for(resource, :as => resource_name, :url => password_path(resource_name), :html => { :method => :put }) do |f| %>
  <%# devise_error_messages! %>
  <%= f.hidden_field :reset_password_token %>

  <p><%= f.label :password, "New password" %><br />
  <%= password_field_tag :name => "user[password]"%></p>
  <%= password_field_tag :name => "user[password_confirmation]"%></p>

  <p><%= f.submit "Change my password" %></p>
<% end %>

<%= render :partial => "devise/shared/links" %>

，但呈现的表单的操作属性具有“/profile”值，并且提交此表单不执行任何操作。

您的表单应该是 password/edit.html.erb

<%# raise resource.inspect %>
<%= form_for(resource, :as => resource_name, :url => password_path(resource_name), :html => { :method => :put }) do |f| %>
  <%# devise_error_messages! %>
  <%= f.hidden_field :reset_password_token %>

   <p><%= f.label :current_password %><br />
   <%= f.password_field :current_password %></p>

  <p><%= f.label :password, "New password" %><br />
  <%= f.password_field :password %></p>

  <p><%= f.label :password_confirmation, "Confirm new password" %><br />
  <%= f.password_field :password_confirmation %></p>

  <p><%= f.submit "Change my password" %></p>
<% end %>

VIEW:

<h3>Change password </h3>
<hr/>
<%= render :template => 'passwords/edit', 
                    :locals => { :resource => current_user, :resource_name => "user" } %>

Controller:

class PasswordsController < ApplicationController
  before_filter :authenticate_user!

  def edit
    @user = current_user
  end

  def update
    @user = current_user
    # raise params.inspect
    if @user.update_with_password(params[:user])
      sign_in(@user, :bypass => true)
      redirect_to root_path, :notice => "Your Password has been updated!"
    else
      render :edit,:locals => { :resource => @user, :resource_name => "user" }
    end
  end
end

Routes:

devise_for :users ,:controllers => {:passwords => "passwords"} do
  end

  resources :passwords

它对我有用;

如果您在 User 周围添加引号，会发生什么情况，如下所示：

<%= render :template => 'passwords/edit', 
                    :locals => { 
                      :resource => current_user, 
                      :resource_name => "User" } %>
