Rails 3手动修改密码 [英] Rails 3 Devise manually change password

问题描述

我试图在我的rails应用程序中使用设计。但是我不明白如何给用户更改密码。我需要一个带有旧密码，新密码和新密码确认的表单。我该怎么做？

如果我在/个人资料页面上使用默认设计表单

 <％= 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 
  

但是对于＃<＃< Class：0x59b9200> ，然后（在评论devise_error_messages！行之后）有
undefined方法'devise_error_messages！'
未定义的方法'＃'为＃< Class：0x59b9200> 错误

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 => 密码已更新！ 
 else 
 render：edit 
 end 
 end 
 end 
  

并使用此问题的建议：渲染Devise编辑密码表单

插入此代码

 <％=呈现：template => 'password / edit'，
：locals => {
：resource => current_user，
：resource_name =>用户}％> 
  

进入/个人资料页面。

password / edit.html.erb包含此代码

 < h2>更改密码< / h2> 
<％＃raise resource.inspect％> 
<％= form_for（resource，：as => resource_name，：url => password_path（resource_name），：html => {：method =>：put}）do | f | ％GT; 
<％＃devise_error_messages！ ％GT; 
<％= f.hidden_​​field：reset_password_token％> 
 
< p><％= f.label：password，新密码％>< br /> 
<％= password_field_tag：name => 用户[口令] ％>< / p为H. 
<％= password_field_tag：name => 用户[password_confirmation] ％>< / p为H. 
 
< p><％= f.submit更改我的密码％>< / p> 
<％end％> 
 
<％= render：partial => devise / shared / links％> 
  

但是，渲染表单对于action属性具有/ profile值，并且提交此表单什么也不做。 p>

解决方案

您的表单应为 password / edit.html.erb

 <％＃raise resource.inspect％> 
<％= form_for（resource，：as => resource_name，：url => password_path（resource_name），：html => {：method =>：put}）do | f | ％GT; 
<％＃devise_error_messages！ ％GT; 
<％= f.hidden_​​field：reset_password_token％> 
 
< p><％= f.label：current_password％>< br /> 
<％= f.password_field：current_password％>< / p> 
 
< p><％= f.label：password，新密码％>< br /> 
<％= f.password_field：password％>< / p> 
 
< p><％= f.label：password_confirmation，确认新密码％>< br /> 
<％= f.password_field：password_confirmation％>< / p> 
 
< p><％= f.submit更改我的密码％>< / p> 
<％end％> 
  

VIEW ：

 < h3>更改密码< / h3> 
< hr /> 
<％= render：template => 'password / edit'，
：locals => {：resource => current_user，：resource_name => user}％> 
  

控制器：

  class PasswordsController< ApplicationController 
 before_filter：authenticate_user！ 
 
 def edit 
 @user = current_user 
 end 
 
 def update 
 @user = current_user 
＃raise params.inspect 
如果@ user.update_with_password（params [：user]）
 sign_in（@user，：bypass => true）
 redirect_to root_path，：notice => 您的密码已更新！ 
 else 
 render：edit，：locals => {：resource => @user，：resource_name => user} 
 end 
 end 
 end 
  

路线：

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

它适用于我;

I try to usung devise in my rails app. But i don't understand how can i give user functionality to change his password. I need a form with fields "old password", "new password" and "new password confirmation". How can i do it?

If i use default devise form on "/profile" page

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

In user.rb contain line

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

But there was undefined method 'devise_error_messages!' for #<#<Class:0x59b9200> and then (after commenting devise_error_messages! line) undefined method 'password' for #<Class:0x59b9200> errors.

I try to use my own 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

and use advise from this question: Rendering the Devise edit Password Form

insert this code

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

into "/profile" page.

passwords/edit.html.erb contain this code

<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" %>

But rendered form has "/profile" value for action attribute and submiting this form do nothing.

解决方案

Your form should be i.e. 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

It works for me;
