Django Admin预先填充用户的电子邮件

Question

我需要一些帮助来在模型中预先填充用户的电子邮件。必须有一种简单的方法，但是我认为我太累了，看不到这个窍门。基本上我需要的是，在用户登录到admin之后，我需要已经使用当前用户的信息填充User模型中的用户，电子邮件和姓名等字段。

您的帮助将不胜感激！ 目前我的模型是这样的：

class ParcareManager(models.Manager):

    def active(self, *args, **kwargs):
        return super(ParcareManager, self).filter(draft=False).filter(parking_on__lte=timezone.now())

class Parcare(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL, blank=True, null=True, default=1, on_delete=True)

    email=models.EmailField(blank=True, null=True)
    # email = models.EmailField(settings.AUTH_USER_MODEL)
    parking_on = models.DateField(auto_now=False, auto_now_add=False,blank=True, null=True)
    parking_off = models.DateField(
        auto_now=False, auto_now_add=False, blank=True, null=True) #plecarea din parcare
    location =models.CharField(max_length=120, default="P1", blank=True, null=True)
    updated = models.DateTimeField(auto_now=True, auto_now_add=False,blank=True, null=True)
    timestamp=models.DateTimeField(auto_now=False, auto_now_add=True,blank=True, null=True)
    venire = models.TimeField(default=datetime.time(9, 00),auto_now=False, auto_now_add=False )
    plecare = models.TimeField(default=datetime.time(
        18, 00), auto_now=False, auto_now_add=False)
    objects = ParcareManager()

    def __str__(self):
        return self.email + " | " + self.location + " | " + str(self.parking_on) + " | " + str(self.parking_off)

    class Meta:
        verbose_name_plural = "parcare"

class Meta:
    ordering = ["-timestamp", "-updated"]

我的管理员是这样的：

from django.contrib import admin

# Register your models here.
from .models import Parcare


class ParcareModelAdmin(admin.ModelAdmin):
    list_display = [ "email","user", "location",
                    "parking_on", "parking_off",  "venire", "plecare"]
    list_display_links = ["email", "user" ]
    list_editable = [ "parking_off", "parking_on","venire", "plecare"]
    list_filter = ["parking_on", "parking_off", "venire",  "plecare"]
    search_fields = ["location", "name"]

    class Meta:
        model = Parcare

    def email(self, obj):
        return obj.user.email

admin.site.register(Parcare, ParcareModelAdmin)

如果是这种情况，则可以尝试以下方法：

def get_form(self, request, obj=None, **kwargs):
    form = super().get_form(request, obj, **kwargs)
    if not obj:
        user = request.user
        form.base_fields['user'].initial = user
        form.base_fields['email'].initial = user.email
    return form

这里是从请求中获取登录的用户对象，然后初始化该用户的值。
