Django - 房间模型需要有多种房间类型的选择。一个房间必须至少有预定义选择中的一种房间类型

房间没有保存到数据库，我该如何改进？有没有更好的办法？

一个属性可以有一个或多个房间。一个房间必须属于一个属性。

我首先创建房间模型

class Room(models.Model):
  property = models.ForeignKey(Property)

  name = models.CharField(max_length=250)

  description = models.TextField(max_length=800)

  image = models.ImageField(upload_to='room_images/', blank=False)

  bar_rate = models.IntegerField(default=0, blank=False)

  max_occupancy = models.IntegerField(default=1, blank=False)

  extra_beds = models.IntegerField(default=0, blank=True)

  price_per_exra_bed = models.IntegerField(default=0, blank=True)

  is_breakfast_included = models.BooleanField(default=False)

  room_type_quantity = models.IntegerField(default=0, blank=False)

  ROOM_TYPES = (
    ('SGL', 'Single'),
    ('TWN', 'Twin'),
    ('DBL', 'Double'),
    ('TRPL', 'Triple'),
    ('STND', 'Standard'),
    ('DLX', 'Deluxe'),
    ('EXET', 'Executive'),
    ('SPR', 'Superior'),
    ('JS', 'Junior Suite'),
    ('ONEBDR', 'One Bedroom'),
    ('TWOBDR', 'Two Bedroom'),
    ('THREEBDR', 'Three Bedroom'),
    ('FOURBDR', 'Four Bedroom'),
    ('FIVEBDR', 'Five Bedroom'),
    ('SIXBDR', 'Six Bedroom'),
    ('SEVENBDR', 'Seven Bedroom'),
   )
  room_type = models.CharField(max_length=1, choices=ROOM_TYPES, default="STND")


def __str__(self):
  return self.name

我创建了一个新表单以允许用户填写表单。里面的forms.py

class RoomForm(forms.ModelForm):
  class Meta:
    model = Room
    exclude = ("property",)

正如你在上面看到的，我排除了属性模型，我不需要将属性信息添加到 RoomForm 中。

在 views.py 中，我修改了 property_add_room 函数以将房间保存到数据库中：

@login_required(login_url='/property/sign-in/')
def property_add_room(request):
  form = RoomForm()

  if request.method == "POST":
    form = RoomForm(request.POST, request.FILES)

    if form.is_valid():
      room = form.save(commit=False)
      room.property = request.user.property
      room.save()
      return redirect(property_room)

  return render(request, 'property/add_room.html', {
     "form": form
  })

这是属性模型。用户拥有一项财产，一项财产必须属于一名用户。

class Property(models.Model):
 user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='property')
 name = models.CharField(max_length=500)
 phone = models.CharField(max_length=500)
 address = models.CharField(max_length=500)
 total_rooms = models.CharField(max_length=500)
 logo = models.ImageField(upload_to='property_logo/', blank=False)
