我从django应用程序进行了注册，但是当我单击``提交''按钮时出现此错误：

分配前引用的本地变量'first_name'请求方法：POST请求URL：http : //127.0.0.1 :8000/accounts/register Django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，在注册Python可执行文件中：C：\ Users \ Asus \ Envs \ test \ Scripts \ python.exe Python版本：3.9.0 Python路径：
[' E：\ django \ Hello_world'，'c：\ users \ asus \ appdata \ local \ programs \ python \ python39 \ python39.zip'，'c：\ users \ asus \ appdata \ local \ programs \ python \ python39 \ DLLs '，'c：\ users \ asus \ appdata \ local \ programs \ python \ python39 \ lib'，'c：\ users \ asus \ appdata \ local \ programs \ python \ python39'，'C：\ Users \ Asus \ Envs \ test”，“ C：\ Users \ Asus \ Envs \ test \ lib \ site-packages']

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')

和html文件是：

<!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上引号。将代码更改为此：

      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']
