• Django Admin 配置和定制基本功能(基本二次开发配置)


    一 列表显示页面

     1. list_display,列表时,定制显示的列

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
        list_display = ('user', 'pwd', 'xxxxx')
     
        def xxxxx(self, obj):
            return "xxxxx"

    2. list_display_links,列表时,定制列可以点击跳转

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
        list_display = ('user', 'pwd', 'xxxxx')
        list_display_links = ('pwd',)

    3. list_filter,列表时,定制右侧快速筛选

    4. list_select_related,列表时,连表查询是否自动select_related

    5. list_editable,列表时,可以编辑的列 

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
        list_display = ('user', 'pwd','ug',)
        list_editable = ('ug',)

    6. search_fields,列表时,模糊搜索的功能

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
         
        search_fields = ('user', 'pwd')

    7. date_hierarchy,列表时,对Date和DateTime类型进行搜索

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
     
        date_hierarchy = 'ctime'

    8. action,列表时,定制action中的操作

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
     
        # 定制Action行为具体方法
        def func(self, request, queryset):
            print(self, request, queryset)
            print(request.POST.getlist('_selected_action'))
     
        func.short_description = "中文显示自定义Actions"
        actions = [func, ]
     
        # Action选项都是在页面上方显示
        actions_on_top = True
        # Action选项都是在页面下方显示
        actions_on_bottom = False
     
        # 是否显示选择个数
        actions_selection_counter = True

    9. ordering,列表时,数据排序规则

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
        ordering = ('-id',)
        或
        def get_ordering(self, request):
            return ['-id', ]

     

    10. empty_value_display = "列数据为空时,显示默认值"

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
        empty_value_display = "列数据为空时,默认显示"
     
        list_display = ('user','pwd','up')
     
        def up(self,obj):
            return obj.user
        up.empty_value_display = "指定列数据为空时,默认显示"

    二  详情页面

    1 .inlines,详细页面,如果有其他表和当前表做FK,那么详细页面可以进行动态增加和删除

    class UserInfoInline(admin.StackedInline): # TabularInline
        extra = 0
        model = models.UserInfo
     
     
    class GroupAdminMode(admin.ModelAdmin):
        list_display = ('id', 'title',)
        inlines = [UserInfoInline, ]

    2. raw_id_fields,详细页面,针对FK和M2M字段变成以Input框形式

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
     
        raw_id_fields = ('FK字段', 'M2M字段',)

    3. fields,详细页面时,显示字段的字段

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
        fields = ('user',)

    4. exclude,详细页面时,排除的字段

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
        exclude = ('user',)

    5. readonly_fields,详细页面时,只读字段

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
        readonly_fields = ('user',)

    6.fieldsets,详细页面时,使用fieldsets标签对数据进行分割显示

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
        fieldsets = (
            ('基本数据', {
                'fields': ('user', 'pwd', 'ctime',)
            }),
            ('其他', {
                'classes': ('collapse', 'wide', 'extrapretty'),  # 'collapse','wide', 'extrapretty'
                'fields': ('user', 'pwd'),
            }),
        )

    7. 详细页面时,M2M显示时,数据移动选择(方向:上下和左右)

    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
        filter_vertical = ("m2m字段",) # 或filter_horizontal = ("m2m字段",)

    8. radio_fields,详细页面时,使用radio显示选项(FK默认使用select)

    radio_fields = {"ug": admin.VERTICAL} # 或admin.HORIZONTAL

    三 其它

    1. 定制HTML模板

    add_form_template = None
    change_form_template = None
    change_list_template = None
    delete_confirmation_template = None
    delete_selected_confirmation_template = None
    object_history_template = None

    2. form = ModelForm,用于定制用户请求时候表单验证

    from app01 import models
    from django.forms import ModelForm
    from django.forms import fields
     
     
    class MyForm(ModelForm):
        others = fields.CharField()
     
        class Meta:
            model = models = models.UserInfo
            fields = "__all__"
     
    @admin.register(models.UserInfo)
    class UserAdmin(admin.ModelAdmin):
     
        form = MyForm
