models.py中有以下内容：

from django.db import models

class LabName(models.Model):
    labsname=models.CharField(max_length=30)
    def __unicode__(self):
     return self.labsname

class ComponentDescription(models.Model):
       lab_Title=models.ForeignKey('Labname')
       component_Name = models.CharField(max_length=30)
       description = models.CharField(max_length=20)
        purchased_Date = models.DateField()
       status = models.CharField(max_length=30)
       to_Do = models.CharField(max_length=30,blank=True) 
       remarks = models.CharField(max_length=30)

       def __unicode__(self):
           return self.component

from django.contrib import admin
from Lab_inventory.models import ComponentDescription,LabName

class ComponentDescriptionAdmin(admin.ModelAdmin):
    list_display= ('lab_Title','component_Name','description','purchased_Date','status','to_Do','remarks')          
    list_filter=('lab_Title','status','purchased_Date')

admin.site.register(LabName)
admin.site.register(ComponentDescription,ComponentDescriptionAdmin)

我的
admin.py中有以下内容：

from django.db import models

class LabName(models.Model):
    labsname=models.CharField(max_length=30)
    def __unicode__(self):
     return self.labsname

class ComponentDescription(models.Model):
       lab_Title=models.ForeignKey('Labname')
       component_Name = models.CharField(max_length=30)
       description = models.CharField(max_length=20)
        purchased_Date = models.DateField()
       status = models.CharField(max_length=30)
       to_Do = models.CharField(max_length=30,blank=True) 
       remarks = models.CharField(max_length=30)

       def __unicode__(self):
           return self.component

from django.contrib import admin
from Lab_inventory.models import ComponentDescription,LabName

class ComponentDescriptionAdmin(admin.ModelAdmin):
    list_display= ('lab_Title','component_Name','description','purchased_Date','status','to_Do','remarks')          
    list_filter=('lab_Title','status','purchased_Date')

admin.site.register(LabName)
admin.site.register(ComponentDescription,ComponentDescriptionAdmin)

我想要的是显示要在实验室标题下显示的组件描述下的字段（与每个实验室标题相关的字段应显示在该实验室名称下）
您使用
list\u display
和
list\u filter
所做的操作与列出LabName对象列表的管理屏幕中显示的列表相关

假设一个
LabName
具有一对多
ComponentDescription
实体，您需要Django在特定
LabName
实体的管理页面中显示属于
LabName
的
ComponentDescription
对象列表。该守则的结构如下：

from django.contrib import admin
from Lab_inventory.models import ComponentDescription,LabName

class ComponentDescriptionInline(admin.TabularInline):
    model = ComponentDescription

class LabNameAdmin(admin.ModelAdmin):
    inlines = [
        ComponentDescriptionInline,
    ]

admin.site.register(LabName, LabNameAdmin)

其中，
TabularInline
是泛型
InlineModelAdmin
的子类
