前言

在Django中有大量的通用类视图，例如ListView,DetailView,CreateView,UpdateView等等，将所有重复的增删改查代码抽象成一个通用类，只需要配置极少量的代码即可实现功能。

使用通用类视图完成找回密码功能

首先引入

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

配置如下：

class MyPasswordResetView(PasswordResetView):
 """重置密码视图"""
 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):
 """重置密码页面，输入两次密码"""
 template_name = 'users/registration/password_change_form.html'
 success_url = reverse_lazy('users:password_reset_complete')


class MyPasswordResetDoneView(PasswordResetDoneView):
 """发送确认重置邮件"""
 template_name = 'users/registration/password_reset_done.html'


class MyPasswordResetCompleteView(PasswordResetCompleteView):
 """完成重置密码"""
 template_name = 'users/registration/password_change_done.html'

其中忘记密码，填写邮箱的模板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="请输入您的邮箱" class="input-material">
    <label for="login-username" class="label-material">邮箱</label>
    {% if form.errors %}
    <div >邮箱输入错误</div>
    {% endif %}
   </div>

    {% csrf_token %}
    <button type="submit"  href="#" rel="external nofollow" class="btn btn-primary">发送确认邮件</button>
   <!-- This should be submit button but I replaced it with <a> for demo purposes-->
   </form>

其中输入新密码模板password_change_form.html页面如下：

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

其中重置密码邮件发送成功的模板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>重置密码邮件发送成功！</h1>

  </div>
  </div>
 </div>

其中密码重置成功password_change_done.html如下：

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