在 Django Web 应用程序的注册页面，我只想询问所需的用户名和电子邮件地址，系统将通过电子邮件将随机生成的密码发送到用户给定的 ID。我该怎么办？
我正在使用 django 2.2.2 和 python 3.7.3。我正在使用 Crispy_forms 来渲染表单。
相关 django 表单文档 here .
我已经在 UserRegisterForm 类的 Meta 类中使用了“排除”变量。查看代码以了解我所做的事情
在forms.py文件中:
class UserRegisterForm(UserCreationForm):
"""
Inheriting the UserCreationForm class to add some additional fields in
the registration form because the #s of fields
in the UserCreationForm class has less fields than required.
We add email field in this extended class.
"""
email = forms.EmailField()
class Meta:
model = User
fields = ("username", "email")
exclude = ("password1", "password2")
我的register.html模板文件:
{% extends "blog/base.html" %}
{% load i18n %}
{% load crispy_forms_tags %}
{% block content %}
<div class="content-section">
<form method="POST">
{% csrf_token %}
<fieldset class="form-group">
<legend>
Join here!
</legend>
{{ form|crispy }}
</fieldset>
<div>
<button>Sign up!</button>
</div>
</form>
<small class="text-muted">
Already have an account? Sign in <a href="{% url "login" %}" class="ml-2">here</a>.
</small>
</div>
{% endblock content %}
我的views.py文件:
def register(request):
"""
Triggered when AnonymousUser clicks on the 'Sign Up' button anywhere on the site
The process:
1. User visits registration page
2. User enters his/her email only.
3. System makes an account in the database & sends an email
to that id with the password.
4. User logs in the website using that password
"""
if not request.user.is_authenticated:
if request.method == "POST":
request.POST = request.POST.copy() # To make the request.POST mutable
request.POST['password1'] = get_random_alphanumeric_password(_max_len=8)
request.POST['password2'] = request.POST['password1']
form = UserRegisterForm(request.POST)
if form.is_valid():
form.save()
# WORKS!
messages.success(request, _(f"Account successfully created"))
send_mail(subject=_(f"KBank - Password for {request.POST['username']}"),
message=_(f"Thanks for signing up at KBank. The password is {request.POST['password1']}"),
from_email=os.environ.get("EMAIL_USER"),
recipient_list=[f"{request.POST['email']}"],
)
messages.info(request, _("Please check your email for password & log in using that"))
return redirect('login')
else:
form = UserRegisterForm()
return render(request, "users/register.html", {"form": form})
else:
return redirect("site-home")
错误是要求输入密码 1 和密码 2 的两个字段仍然显示在我的注册页面上。
最佳答案
fields 和 exclude 属性适用于从模型创建的字段。 password1和password2字段不是来自模型，它们是直接在UserCreationForm上定义的额外字段。
您可以重写 init 方法以从表单中删除这些方法，但我不确定您为什么要这样做。我也不明白为什么，如果你不想显示表单，你仍然想改变 request.POST 来传递它们。实际上你应该只使用标准的 ModelForm，然后在保存时设置随 secret 码。所以:
class UserRegisterForm(forms.ModelForm):
class Meta:
model = User
fields = ("username", "email")
def register(request):
if not request.user.is_authenticated:
if request.method == "POST":
form = UserRegisterForm(request.POST)
if form.is_valid():
user = form.save(commit=False)
new_password = get_random_alphanumeric_password(_max_len=8)
user.set_password(new_password)
user.save()
messages.success(request, _(f"Account successfully created"))
send_mail(subject=_(f"KBank - Password for {user.username}"),
message=_(f"Thanks for signing up at KBank. The password is {new_password}"),
from_email=os.environ.get("EMAIL_USER"),
recipient_list=[user.email],
)
...
(请注意，您应该在电子邮件中使用来自用户对象的数据，而不是原始 POST 数据。)
关于python - 即使在 forms.py 中 UserRegistrationForm 的 Meta 类中使用 "exclude"变量后，password1、password2 的字段也会显示(在注册页面)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56592537/
