django进阶-modelform&admin action

先看效果图:

from django.contrib import admin

# Register your models here.
from app01 import models

def make_forbidden(modelAdmin, request, queryset):  #queryset：选中的集合；modelAdmin代表BookAdmin类,相当于self
print("----->", modelAdmin,request,queryset)
queryset.update(status="forbidden")  #更改选中的为禁书
#使action框有选项set to forbidden
make_forbidden.short_description = "Set to forbidden"

class BookAdmin(admin.ModelAdmin):  #定制book，需将类当作参数传给admin
# list_display不能显示多对多的，比如authors:
# (admin.E109) The value of 'list_display[2]' must not be a ManyToManyField.
list_display = ("id","name", "publisher","publish_date","colored_status","status")  #定制为三列

search_fields = ("name", "publisher__name")   #__表示出版社关联到名字
list_filter = ("publisher", "publish_date")  #过滤
list_editable = ("name", "publish_date")     #可修改
list_per_page = 10   #每页显示数量
#即便只有一个值也要加逗号，不然就不当成元组了
#The value of 'filter_horizontal' must be a list or tuple.
filter_horizontal = ("authors",)   #选择作者时进行定制　PS:用于多对多关联
raw_id_fields = ("publisher",)    #选择出版社时进行定制　PS:用于FK外键关联

actions = [make_forbidden]

admin.site.register(models.Author)
admin.site.register(models.Book, BookAdmin)
admin.site.register(models.Publisher)
