Django admin注册model究竟要怎么写才优雅

比如在Django admin 注册models时,会用到。

对于APP里自带的models,可以使用这种方式注册。

from django.contrib import admin

# Register your models here.

from django.apps import apps
from django.contrib.admin.sites import AlreadyRegistered

app_models = apps.get_app_config("crm").get_models()  # 获取app:crm下所有的model,得到一个生成器
# 遍历注册model
for model in app_models:
    try:
        admin.site.register(model)
    except AlreadyRegistered:
        pass

但是如果想要扩展models在Django admin页面的显示效果时,就没法用上面的方法了,但是可以使用装饰器来简化书写的代码量。

from django.contrib import admin

# Register your models here.

from bbs import models


@admin.register(models.Article)
class ArticleAdmin(admin.ModelAdmin):
    list_display = ('title', 'category', 'author', 'pub_date', 'last_modify', 'status', 'priority')


@admin.register(models.Comment)
class CommentAdmin(admin.ModelAdmin):
    list_display = ('article', 'parent_comment', 'comment_type', 'comment', 'user', 'date')


@admin.register(models.Category)
class CategoryAdmin(admin.ModelAdmin):
    list_display = ('name', 'set_as_top_menu', 'position_index')


admin.site.register(models.UserProfile)

补充一个获取模块中类名的方法。

import inspect

# 找出模块里所有的类名
def get_classes(arg):
    classes = []
    clsmembers = inspect.getmembers(arg, inspect.isclass)
    for (name, _) in clsmembers:
        classes.append(name)
    return classes
