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
