用户表单未显示基于 django class 的视图
User Form not showing django class based views
我在医院管理系统上工作，有 5-6 种不同类型的用户，如患者、医生、护士、会计师、接待员等。我使用 AbstractUser 扩展了用户模型，它具有所有用户的公共字段，如 DoB、地址等。
models.py
class User(AbstractUser):
# user_type = models.CharField(choices=USER_TYPES, default='patient', max_length=20)
date_of_birth = models.DateField(blank=True, null=True, validators=[validate_future_date])
phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+9199999999'. Up to 15 digits allowed.")
mobile_num = models.CharField(max_length=15, validators=[phone_regex])
created = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
date_joining = models.DateTimeField(auto_now_add=True)

我正在尝试分离用于注册用户和为每个用户创建配置文件的通用逻辑，即 UserRegistrationMixin 具有创建用户的逻辑，而 PatientRegistrationView 将创建患者的配置文件及其权限。但是当我从 UserRegistrationMixin 继承时，user_form 不显示。我对 Django 的 GCBV 没有太多经验。提前致谢。
问题出在您的 get 方法上。 get_context_data 没有调用。可以查看View的get方法 class:
def get(self, request, *args, **kwargs):
"""Handle GET requests: instantiate a blank version of the form."""
return self.render_to_response(self.get_context_data())
您可以调用 context = self.get_context_data() 并将 context 传递给 render_to_response。
