如何在将密码保存到用户模型 Django 之前对其进行加密？答案

【问题标题】：How to Encrypt Password before saving it to User Model Django?如何在将密码保存到用户模型 Django 之前对其进行加密？

【问题描述】：

我创建了一个用户注册页面，将用户添加到 Django 中的用户模型

但在保存数据时，密码并未加密，即仅以文本形式存储。这会在用户尝试登录时产生问题（因为 Django 尝试解密原始密码，但它们都不匹配）。

另外，我正在扩展用户模型，以便添加有关保存在配置文件模型中的用户的更多信息（使用一对一链接）

views.py

def user_signup(request):
    if request.method == "POST":
        user_form = userSignup(request.POST)
        phone = request.POST['phone']
        address = request.POST['address']
        pincode = request.POST['pincode']
        
        if user_form.is_valid() :
            user = user_form.save()
            auth.login(request,user)
            userdata = User.objects.all()
            for userinfo in userdata:
                if userinfo.username == user.username:
                    user_id=user.id
            update_data = Profile.objects.get(pk = user_id)
            update_data.address=address
            update_data.phone=phone
            update_data.pincode=pincode
            update_data.save()
            return redirect('/')

        else:
            return HttpResponse(" SIGNUP FAILED")

    else:
        form = userSignup()
        profile_form = userSignup_profile()
        return render(request,"user_signup.html",{'form':form, 'profile_form':profile_form})


def user_logout(request):
    auth.logout(request)
    return redirect('/')

user_signup.html

<body>
    <form action="user_signup" method="POST"> 
        {% csrf_token %}
        {{form.as_p}}
        {{ profile_form.as_p}}
        <button class="primary" type="submit" >SIGNUP </button>
    </form>
</body>

Models.py

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    phone = models.CharField(max_length=10)
    address = models.TextField(max_length=200)
    pincode = models.IntegerField()

forms.py

class userSignup(forms.ModelForm):
    password = forms.CharField(max_length=50, widget = forms.PasswordInput())

    class Meta:
        model = User
        fields = ('first_name', 'last_name','username', 'password',  'email')

如何以加密形式保存新的用户密码，而不是实际密码？？

【问题讨论】：

set_password

标签： django django-models django-forms django-registration django-users

【解决方案1】：

import crypt
# To encrypt the password. This creates a password hash with a random salt.
password_hash = crypt.crypt(password)

# To check the password.
valid_password = crypt.crypt(cleartext, password_hash) == password_hash

【解决方案2】：

Django make_password (source code) 函数将纯文本密码转换为适合存储在持久数据库中的哈希值。

当这个函数已经存在时，你绝对不想尝试使用你自己的加密和散列函数来存储密码。

只需将您的views.py 编辑为：

from django.contrib.auth.hashers import make_password

def user_signup(request):
    if request.method == "POST":
        user_form = userSignup(request.POST)
        phone = request.POST['phone']
        address = request.POST['address']
        pincode = request.POST['pincode']

        if user_form.is_valid() :
            # Hash password using make_password() function
            user = user_form.save(commit=False)
            user.password = make_password(user.password)
            user.save()

            ...

【讨论】：

它没有用。 Exception Type : AttributeErrorException Value: 'userSignup' object has no attribute 'password'

【解决方案3】：

# You have to import make_password

from django.contrib.auth.hashers import make_password

# you have to pass string as parameter
password = "123"
make_password(password)



# You can write your code like this:-


def user_signup(request):
    if request.method == "POST":
        user_form = userSignup(request.POST)
        phone = request.POST['phone']
        address = request.POST['address']
        pincode = request.POST['pincode']

        if user_form.is_valid() :
            user = user_form.save(commit=False)
            user.password = make_password("123")
            user.save()
            .......
            .......
