我从注册了我的django应用程序。但当我点击提交按钮时，我会收到这个错误：
赋值前引用的局部变量"first_name"请求方式：POST请求URL:http://127.0.0.1:8000/accounts/registerDjango版本：3.1.4异常类型：UnboundLocalError异常值：
分配前引用的本地变量"first_name"异常位置：E:\django\Hello_world\accounts\views.py，第8行，在寄存器中Python可执行文件：C:\Users\Asus\Envs\test\Scripts\Python.exePython版本：3.9.0Python路径：

我的代码是
views.py
def register(request):
if request.method == 'POST':
first_name = request.POST[first_name]
last_name = request.POST[last_name]
username = request.POST[username]
email = request.POST[email]
password1 = request.POST[password1]
password2 = request.POST[password2]
user = User.objects.create_user(username=username, email=email, password=password1, first_name=first_name, last_name=last_name)
user.save();
print('user created successfully')
return redirect('/')
else:
return render(request, 'register.html')
html文件为：
register.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Registration</title>
</head>
<body>
<form action="register" method="post">
{% csrf_token %}
<input type="text" name = 'first_name' placeholder="First Name"><br>
<input type="text" name = 'last_name' placeholder="Last Name"><br>
<input type="text" name = 'username' placeholder="Username"><br>
<input type="email" name = 'email' placeholder="E-mail"><br>
<input type="password" name = 'password1' placeholder="Password"><br>
<input type="password" name = 'password2' placeholder="Confirm Password"><br>
<input type="submit">
</form>
</body>
</html>
您忘记在字典键周围加引号了。将您的代码更改为：
first_name = request.POST['first_name']
last_name = request.POST['last_name']
username = request.POST['username']
email = request.POST['email']
password1 = request.POST['password1']
password2 = request.POST['password2']
