from django.contrib import admin
from models import *

admin.site.register(HeroInfo)

class HeroAdmin(admin.ModelAdmin):
    ...

admin.site.register(HeroInfo,HeroAdmin)

@admin.register(HeroInfo)
class HeroAdmin(admin.ModelAdmin):

class HeroAdmin(admin.ModelAdmin):
    actions_on_top = True
    actions_on_bottom = True

在models.py文件中
from django.db import models
from tinymce.models import HTMLField
from django.utils.html import format_html

class HeroInfo(models.Model):
    hname = models.CharField(max_length=10)
    hcontent = HTMLField()
    isDelete = models.BooleanField()
    def hContent(self):
        return format_html(self.hcontent)

在admin.py文件中
class HeroAdmin(admin.ModelAdmin):
    list_display = ['hname', 'hContent']

在models.py中HeroInfo类的代码改为如下：
    def hContent(self):
        return format_html(self.hcontent)
    hContent.admin_order_field = 'hname'

在models.py中为HeroInfo类增加方法hName：
    def hName(self):
        return self.hname
    hName.short_description = '姓名'
    hContent.short_description = '内容'

在admin.py页中注册
class HeroAdmin(admin.ModelAdmin):
    list_display = ['hName', 'hContent']

class HeroAdmin(admin.ModelAdmin):
    ...
    list_filter = ['hname', 'hcontent']

class HeroAdmin(admin.ModelAdmin):
    ...
    list_per_page = 10

class HeroAdmin(admin.ModelAdmin):
    ...
    search_fields = ['hname']

class HeroAdmin(admin.ModelAdmin):
    ...
    fields = [('hname', 'hcontent')]

class HeroAdmin(admin.ModelAdmin):
    ...
    fieldsets = (
        ('base', {'fields': ('hname')}),
        ('other', {'fields': ('hcontent')})
    )

class HeroInline(admin.TabularInline):
    model = HeroInfo

class BookAdmin(admin.ModelAdmin):
    inlines = [
        HeroInline,
    ]
