Django_Admin

创建Django_Admin 管理账户

D:githubDjango_Aadmin>python manage.py createsuperuser
Username (leave blank to use 'dpad'): root
Email address:
Password:    # 密码有复杂度要求
Password (again):
Superuser created successfully.

添加表到 Django_Admin 中进行管理

from django.contrib import admin
from app01 import models

# 添加 Department 表到 Django_Admin 管理
admin.site.register(models.Department)

设置显示为 正常名而非 UserInfo object

1.在创建表的时候，添加__str__(self)

class UserInfo(models.Model):
    """
    用户表
    """
    username = models.CharField(max_length=32)
    email = models.EmailField(max_length=32)
    dp = models.ForeignKey(to="Department")

    def __str__(self):
        return self.username

定制当前列表页面，显示哪几列数据admin.py 文件中

from django.contrib import admin
from app01 import models

# 方法一
class UserInfoConfig(admin.ModelAdmin):
    # 定制当前列表页面，显示哪几列数据 
    list_display = ["username", "email", "dp"]
    # list_display_links = ["email"]              # 设置 可点击 <a> 标签在哪个 字段上
# 继承定义的 UserInfoConfig 类
admin.site.register(models.UserInfo, UserInfoConfig)


# 方法二
@admin.register(models.UserInfo)                 # 通过装饰器实现
class UserInfoConfig(admin.ModelAdmin):
    list_display = ("username", "email", "dp")   # 第一个参数可以是列表

自定义编辑列

1.定义编辑列的函数值

from django.contrib import admin

from app01 import models


@admin.register(models.UserInfo)
class UserInfoConfig(admin.ModelAdmin):
    list_display = ("username", "email", "dp", "edit", "remove")
    list_display_links = ["edit", "remove"]

    def edit(self, obj):
        return "编辑"

    def remove(self, obj):
        return "删除"

自定义分组功能

from django.contrib import admin
from app01 import models

@admin.register(models.UserInfo)
class UserInfoConfig(admin.ModelAdmin):
    list_display = ("username", "email", "dp", "edit", "remove")
    list_display_links = ["edit", "remove"]

    # ##分组查询 过滤器
    list_filter = ["dp"]

    def edit(self, obj):
        return "编辑"

    def remove(self, obj):
        return "删除"

# 添加 Department 表到 Django_Admin 管理
admin.site.register(models.Department)

自定义指定的列，处于可修改状态

from django.contrib import admin
from app01 import models


@admin.register(models.UserInfo)
class UserInfoConfig(admin.ModelAdmin):
    list_display = ("username", "email", "dp", "edit", "remove")
    list_display_links = ["edit", "remove"]
    list_filter = ["dp"]
    
    # 时刻处于可修改状态,但该列不能处于可点击<a> 标签状态
    list_editable = ('username',)

    def edit(self, obj):
        return "编辑"

    def remove(self, obj):
        return "删除"

# 添加 Department 表到 Django_Admin 管理
admin.site.register(models.Department)

自定义指定的列，可用于模糊查询(出现搜索框)

from django.contrib import admin
from app01 import models


@admin.register(models.UserInfo)
class UserInfoConfig(admin.ModelAdmin):
    list_display = ("username", "email", "dp", "edit", "remove")
    list_display_links = ["edit", "remove"]
    list_editable = ('username',)
    list_filter = ["dp"]

    # 可用于模糊查询的列
    search_fields = ["username", "email",]

    def edit(self, obj):
        return "编辑"

    def remove(self, obj):
        return "删除"

# 添加 Department 表到 Django_Admin 管理
admin.site.register(models.Department)

定义编辑页面 上下都有可点击保存按钮

from django.contrib import admin
from app01 import models

@admin.register(models.UserInfo)
class UserInfoConfig(admin.ModelAdmin):
    list_display = ("username", "email", "dp", "edit", "remove")
    list_display_links = ["edit", "remove"]
    list_filter = ["dp"]
    search_fields = ["username", "email",]

    # 定义编辑页面 上下都有可点击保存按钮
    save_on_top = True

    def edit(self, obj):
        return "编辑"

    def remove(self, obj):
        return "删除"

# 添加 Department 表到 Django_Admin 管理
admin.site.register(models.Department)

定义选中动作,批量执行操作

from django.contrib import admin

from app01 import models


@admin.register(models.UserInfo)
class UserInfoConfig(admin.ModelAdmin):
    list_display = ("username", "email", "dp", "edit", "remove")
    list_display_links = ["edit", "remove"]
    list_filter = ["dp"]
    search_fields = ["username", "email",]
    save_on_top = True
    # fields = ('username',"email")

    def edit(self, obj):
        return "编辑"

    def remove(self, obj):
        return "删除"

    # 定制Action行为具体方法
    def func(self, request, queryset):
        print(self, request, queryset)
        print("可以拿到选中的 ID 值：", request.POST.getlist('_selected_action'))

        id_list = request.POST.getlist('_selected_action')
        # 数据库操作,删除选中的 id 数据
        # models.UserInfo.objects.filter(id__in=id_list).delete()

    func.short_description = "自定义删除选中"
    actions = [func, ]       # 会触发执行 func 函数

# 添加 Department 表到 Django_Admin 管理
admin.site.register(models.Department)
