Django通用类视图实现忘记密码重置密码功能

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 id="login-username" 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 style="color: red">邮箱输入错误</div>
              {% endif %}
            </div>

              {% csrf_token %}
              <button type="submit" id="login" href="#" 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 id="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' %}">回到首页</a>
      </div>
    </div>
  </div>

最后配置路由

path('password/reset/', view=MyPasswordResetView.as_view(), name='password_reset'), # password_reset
path('password/reset/done/', MyPasswordResetDoneView.as_view(), name='password_reset_done'),  # password_reset_done

url(r'^reset/(?P<uidb64>[0-9A-Za-z_-]+)/(?P<token>[0-9A-Za-z]{1,13}-[0-9A-Za-z]{1,20})/$',
    view=MyPasswordResetConfirmView.as_view(), name='password_reset_confirm'), # reset
path('reset/done/', MyPasswordResetCompleteView.as_view(), name='password_reset_complete'),

效果如下：
