前言

在Django中有大量的通用類視圖，例如ListView,DetailView,CreateView,UpdateView等等，將所有重復(fù)的增刪改查代碼抽象成一個(gè)通用類，只需要配置極少量的代碼即可實(shí)現(xiàn)功能。

使用通用類視圖完成找回密碼功能

首先引入

from django.contrib.auth.views import PasswordResetView, PasswordResetConfirmView, / PasswordResetDoneView, PasswordChangeView, PasswordChangeDoneView, / PasswordResetCompleteView

配置如下：

class MyPasswordResetView(PasswordResetView): """重置密碼視圖""" template_name = 'users/registration/forget_pwd.html' form_class = ForgetForm success_url = reverse_lazy("users:password_reset_done") email_template_name = 'users/registration/password_reset_email.html'class MyPasswordResetConfirmView(PasswordResetConfirmView): """重置密碼頁面，輸入兩次密碼""" template_name = 'users/registration/password_change_form.html' success_url = reverse_lazy('users:password_reset_complete')class MyPasswordResetDoneView(PasswordResetDoneView): """發(fā)送確認(rèn)重置郵件""" template_name = 'users/registration/password_reset_done.html'class MyPasswordResetCompleteView(PasswordResetCompleteView): """完成重置密碼""" template_name = 'users/registration/password_change_done.html'

其中忘記密碼，填寫郵箱的模板forget_pwd.html模板如下：

   <form method="post" class="form-validate" action="{% url 'users:password_reset' %}">   <div class="form-group">    <input  type="text" name="email" required data-msg="請輸入您的郵箱" class="input-material">    <label for="login-username" class="label-material">郵箱</label>    {% if form.errors %}    <div >郵箱輸入錯(cuò)誤</div>    {% endif %}   </div>    {% csrf_token %}    <button type="submit"  href="#" rel="external nofollow" class="btn btn-primary">發(fā)送確認(rèn)郵件</button>   <!-- This should be submit button but I replaced it with <a> for demo purposes-->   </form>

其中輸入新密碼模板password_change_form.html頁面如下：

<form  method="post"> {% csrf_token %} {{ form|crispy }} <div class="form-group"> <button type="submit" class="btn btn-primary button-submit">確認(rèn)更改</button> </div></form>

其中重置密碼郵件發(fā)送成功的模板password_reset_done.html如下：

 <div class="col-lg-6 bg-white">  <div class="form d-flex align-items-center">  <div class="content">   <h1>重置密碼郵件發(fā)送成功！</h1>  </div>  </div> </div>

其中密碼重置成功password_change_done.html如下：

 <div class="container"> <div class="row">  <div class="col-md-6 offset-md-3">  <h1>重置密碼成功！</h1>  <a href="{% url 'index' %}" rel="external nofollow" >回到首頁</a>  </div> </div> </div>
