This article mainly introduces the example of the forgotten password retrieval function through email in Django development. Now I share it with you and give it as a reference. Let’s take a look together

1. Process analysis:

1. Click Forgot Password====》forget.html page and enter Email and verification code, send an email with the verification link URL ====》Sent successfully, jump to send_success.html prompt

2. Find the verification link URL in the email, visit the reset password URL reset.html= ==》Reset password and submit data. If successful, return to the homepage. If failed, return error message

1.users/forms .py file

from django import forms
from captcha.fields import CaptchaField


.......

#forget.html中，用于验证邮箱格式和验证码
class ForgetForm(forms.Form):
  email=forms.EmailField(required=True)
  captcha=CaptchaField(error_messages={&#39;invalid&#39;:&#39;验证码错误&#39;})

#reset.html中，用于验证新设的密码长度是否达标
class ResetForm(forms.Form):
  newpwd1=forms.CharField(required=True,min_length=6,error_messages={&#39;required&#39;: &#39;密码不能为空.&#39;, &#39;min_length&#39;: "至少6位"})
  newpwd2 = forms.CharField(required=True, min_length=6, error_messages={&#39;required&#39;: &#39;密码不能为空.&#39;, &#39;min_length&#39;: "至少6位"})

2 Relevant code in .users/views.py:

......
from django.shortcuts import render,redirect
from django.http import HttpResponse
from users.form import ForgetForm,ResetForm
from .models import UserProfile
from django.contrib.auth.hashers import make_password
from apps.utils.email_send import send_register_email
from .models import EmailVerifyRecord

......

class ForgetPwdView(View):
  &#39;&#39;&#39;忘记密码&#39;&#39;&#39;
  def get(self,request):
    forget_form=ForgetForm()
    return render(request,&#39;forget.html&#39;,{&#39;forget_form&#39;:forget_form})
  def post(self,request):
    forget_form = ForgetForm(request.POST)
    if forget_form.is_valid():
      email=request.POST.get(&#39;email&#39;,&#39;&#39;)
      send_register_email(email,&#39;forget&#39;)
      return render(request,&#39;send_success.html&#39;)
    else:
      return render(request,&#39;forget.html&#39;,{&#39;forget_form&#39;:forget_form})


class ResetView(View):
  &#39;&#39;&#39;重置密码&#39;&#39;&#39;
  def get(self,request,active_code):
    record=EmailVerifyRecord.objects.filter(code=active_code)
    print(record)
    if record:
      for i in record:
        email=i.email
        is_register=UserProfile.objects.filter(email=email)
        if is_register:
          return render(request,&#39;pwd_reset.html&#39;,{&#39;email&#39;:email})
    return redirect(&#39;index&#39;)


#因为<form>表单中的路径要是确定的，所以post函数另外定义一个类来完成
class ModifyView(View):
  """重置密码post部分"""
  def post(self,request):
    reset_form=ResetForm(request.POST)
    if reset_form.is_valid():
      pwd1=request.POST.get(&#39;newpwd1&#39;,&#39;&#39;)
      pwd2=request.POST.get(&#39;newpwd2&#39;,&#39;&#39;)
      email=request.POST.get(&#39;email&#39;,&#39;&#39;)
      if pwd1!=pwd2:
        return render(request,&#39;pwd_reset.html&#39;,{&#39;msg&#39;:&#39;密码不一致！&#39;})
      else:
        user=UserProfile.objects.get(email=email)
        user.password=make_password(pwd2)
        user.save()
        return redirect(&#39;index&#39;)
    else:
      email=request.POST.get(&#39;email&#39;,&#39;&#39;)
      return render(request,&#39;pwd_reset.html&#39;,{&#39;msg&#39;:reset_form.errors})

3. Create new forget.html, success_send.html, pwd_reset.html

#forget.html

<!DOCTYPE html>
{% load staticfiles %}
<html lang="en">

<head>
  <meta charset="UTF-8">
  <title>忘记密码</title>

<style>
.out{
  width: 500px;
  height: 900px;
  margin: 0 auto;
  margin-top: 100px;
}
</style>
</head>
<body>


  <p class="out">
    <h1>真粗心，忘了密码吧？快通过邮箱找回密码吧！</h1>
    <form method="post" action="{% url &#39;forget_pwd&#39; %}">
      <P><span>邮箱：</span><input type="text" name="email"></P>
      <P><span>验证码：</span>{{ forget_form.captcha }}</P>
      {% csrf_token %}
      <p><input type="submit" value="确认发送验证邮件"></p>
    </form>
    <h1>{{ forget_form.errors }}</h1>
  </p>


</body>
</html>

Copy after login

#success_send.html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">

}
</style>
</head>
<body>


  <p class="out">
    <h1>可以重新设置一个好记的新密码啦！</h1>
    <form method="post" action="{% url &#39;modify&#39; %}">
      <P><span>新密码：</span><input type="password" name="newpwd1" placeholder="至少6位"></P>
      <P><span>确认新密码：</span><input type="password" name="newpwd2" placeholder="至少6位"></P>
      {% csrf_token %}
      <input type="hidden" name="email" value="{{ email }}">
      <p><input type="submit" value="确认"></p>
    </form>
    <h1>{{ msg }}</h1>

4. Configure related urls.py ：

......

urlpatterns = [

  #忘记密码
  path(&#39;forget/&#39;,ForgetPwdView.as_view(),name=&#39;forget_pwd&#39;),
  #重置密码
  path(&#39;reset/<str:active_code>&#39;,ResetView.as_view(),name=&#39;reset&#39;),
  path(&#39;modify/&#39;,ModifyView.as_view(),name=&#39;modify&#39;),
