Live video source code, reset the relevant changes of the current password

Live video source , Relevant changes to reset the current password
One 、 Scenario requirements
stay allauth The default way to reset the password in is after the user sends the request to reset the password , Send a link to reset the password to the user's email to reset the password , If you use QQ Mailbox SMTP service , You can only send... At most in a day 50 Messages , This obviously does not meet the demand , If you deploy a mail server or apply for a corporate mailbox to achieve this function , I can't afford to spend thousands of years . So in small and medium-sized projects , There is a compromise , That is, users enter their own ID card [ Here is the telephone as an example ] You can reset the corresponding account password .

Two 、 Rewrite the form model
stay form.py Add form model （ Deal with mobile phone numbers ）

from django import forms

#  Rewrite the reset password form 
class ResetPasswordForm(forms.Form):
    """
     Reset password form , Mobile phone number verification is required 
    """

    tel = forms.CharField(max_length=20, required=True, label='Telephone')

    #  Get the phone number 
    def clean_identity_tel(self):
        tel = self.cleaned_data['tel']
        print(tel)
        """
         Because of the use of get Get objects , If not, an error will be reported , So here we use filter
         Get failure returns an empty object list 
         stay UserProfile Filter qualified users in , Return user name 
        """
        username = UserProfile.objects.filter(tel=tel)
        if not username:
            raise forms.ValidationError(" Wrong cell phone number !!")

        return self.cleaned_data['tel']

    def save(self, request, **kwargs):
        return self.cleaned_data['tel']

3、 ... and 、 rewrite view View function class
allauth The class view for resetting passwords in is located in allauth.account.views.PasswordResetView, We need to be in views.py Inherits this class and overrides its post Method .

stay view.py The view function
Be careful ！！： there default_token_generator The function is allauth Medium form.py Function of , No django.contib,auth.token Of , Otherwise it will be reported bad token error , Because it generates token The method is different （ And email, etc ）

from allauth.account.forms import default_token_generator,SignupForm  #  Be careful ！！ token Generating reality allauth Inside , No django Bring your own token generator 
from allauth.account.utils import user_pk_to_url_str
from allauth.account.views import PasswordResetView
from django.contrib.auth.decorators import login_required
from django.contrib.auth.models import User
from django.http import HttpRequest
from django.shortcuts import render, get_object_or_404, reverse, redirect, HttpResponseRedirect

from userprofile.forms import UseProfileForm, ResetPasswordForm
from userprofile.models import UserProfile


#  Rewrite the reset password form 
class CustomPasswordResetView(PasswordResetView):

    def post(self, request, *args, **kwargs):
        reset_password_form = ResetPasswordForm(request.POST)
        if reset_password_form.is_valid():

            #  Screen out from the phone   User object 
            tel = reset_password_form.clean_identity_tel()
            # UseProfile  Due to user Of the same property  username
            username = UserProfile.objects.get(tel=tel)
            user = User.objects.get(username=username)
            #  Check whether the parameter is transferred   token 
            token_generator = kwargs.get(
                "token_generator", default_token_generator)
            #  No generation token
            temp_key = token_generator.make_token(user)
            #  Reverse resolution path ,（ And herald board parameters ）
            path = reverse(
                "account_reset_password_from_key",
                kwargs=dict(uidb36=user_pk_to_url_str(user), key=temp_key),
            )
            #  Establish an absolute path under the root directory (self = request)
            url = HttpRequest.build_absolute_uri(request, path)
            #  Redirect to the change password link 
            return redirect(url)

        else:
            return render(request, 'account/telephone_error.html', {
    'content': " Telephone error ( Form format error ）"})

#  Be careful   You can't add... Here  login_required  The limitation of ！  Otherwise, the login page   If you forget your password, you will successfully jump to the page ！
password_reset = CustomPasswordResetView.as_view()

stay setting.py Add the configuration （ Rewrite form options ）

ACCOUNT_FORMS = ({
    
    'reset_password': 'Userprofile.forms.ResetPasswordForm'
})

Four 、 Configure project routing
Be careful ！！！： stay introduce When the extended model applies routing allauth application and userprofile Who is at the top must be considered , Otherwise, there will be page failure or error reporting in routing coverage ！！（ General default allauth On the top ）, Here, in order to reset the password , Must let account/password/reset Can't go allauth Registered view class for , It can't be modified allauth Source code , At this point, we use inheritance and in project Route modification priority , Give priority to expanding the application model Rewrite password class .

project urls.py

from django.contrib import admin
from django.urls import path, include

import userprofile.views

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', userprofile.views.profile),  #  home page   Is the information page （ When not logged in   Auto jump to login page ）
    #  Pay attention to the end of the route   One  /
    path('accounts/password/reset/', userprofile.views.password_reset, name='account_reset_password'),
    path('accounts/', include('allauth.urls')),
    path('accounts/', include('userprofile.urls'))
]
