我有以下模型

from django.db import models

# Create your models here.

class Post(models.Model):
    text = models.TextField()

    def __str__(self):
        return self.text[:50]


POWER_CHOICES= (('O', 'ON'),
                ('F','OFF')
        )

STATE_CHOICES =(('AV','Available'),
               ('U','In Use '),
               ('NU','Do Not Use')                
       )

class Device(models.Model):

   name = models.CharField(unique=True,max_length=50 )

   ipaddress=models.ForeignKey('Ipaddress', on_delete=models.CASCADE,)

   devicetype= models.ForeignKey('DeviceType', on_delete=models.CASCADE)
   model= models.ForeignKey('DeviceModel', on_delete=models.CASCADE)
   description= models.TextField(max_length=400)
   location= models.ForeignKey('Location', on_delete=models.CASCADE)
   group= models.ForeignKey('DeviceGroup', on_delete=models.CASCADE)
   managment= models.CharField(max_length=100)
   power= models.CharField(max_length=6, choices=POWER_CHOICES)
   offtime= models.CharField(max_length=30)
   state= models.CharField(max_length=10, choices=STATE_CHOICES)
   user= models.CharField(max_length=100)
#   department= models.ForeignKey('Department',on_delete=models.CASCADE)
   comments= models.CharField(max_length=200)

   def __unicode__(self):
        return self.name[:50]

class DeviceType(models.Model):
    name= models.CharField(max_length=100, …

我正在使用内置函数为许多字段建立自动完成功能：https : //docs.djangoproject.com/en/2.0/ref/contrib/admin/#django.contrib.admin.ModelAdmin.autocomplete_fields

我有以下模型：

 class Ipaddress(models.Model):
        ipaddress=models.CharField(max_length=20)
        slug = models.SlugField(unique=True)
        machinename=models.CharField(max_length=500)
        user=models.CharField(max_length=200)
        department= models.ForeignKey('Department',on_delete=models.CASCADE,default='Empty')
        location= models.ForeignKey('Location', on_delete=models.CASCADE)
        updated = models.DateField("Date Updated",null=True)
        note =models.TextField()

    def __str__(self):
        return self.ipaddress[:50]

class Department(models.Model):
    name= models.CharField(max_length=100, unique=True)
    def __str__(self):
        return self.name[:50] 

class Location(models.Model):
    description= models.CharField(max_length=100, unique=True)
    def __str__(self):
        return self.description[:50] 

管理员页面在这里：

from django.contrib import admin
from pages.models import  Ipaddress, DeviceGroup, Location,Department,
from django_admin_listfilter_dropdown.filters import DropdownFilter, RelatedDropdownFilter

class IpaddressAdmin(admin.ModelAdmin):
        prepopulated_fields = {'slug': ('ipaddress',)}

        search_fields = ['ipaddress']
        autocomplete_fields = ['department',]

        list_display = ('ipaddress', 'machinename', 'user', 'department','location','updated',) …
