        url(r'^password_change/done/$', wrap(self.password_change_done, cacheable=True),name='password_change_done'),
     
    3. app01/models.py
 
            from django.db import models
            class UserInfo(models.Model):
                user = models.CharField(max_length=32)
                email = models.EmailField()

    models.UserInfo: admin.ModelAdmin(models.UserInfo,admin.site)
    models.UserGroup: admin.ModelAdmin(models.UserGroup,admin.site)
}

ModelAdmin中提供可定制功能

1. list_display，列表时，定制显示的列

models.py

    from django.db import models

    class UserGroup(models.Model):
        title = models.CharField(max_length=32)

    class UserInfo(models.Model):
        user = models.CharField(max_length=32)
        email = models.EmailField()

        def __str__(self):
            return self.user

事例一: (显示类的列)

admin.py
    from django.contrib import admin
    from app01 import models
    from django.http import HttpResponse

    class UserInfoModelAdmin(admin.ModelAdmin):

        list_display = ('user','email')
        
        #自定义页面
        # def changelist_view(self, request, extra_context=None):
        #     return HttpResponse("....")

    admin.site.register([models.UserInfo],UserInfoModelAdmin)
    admin.site.register(models.UserGroup,admin.ModelAdmin)



事例二: (自定义类的列)

    from django.contrib import admin
    from app01 import models
    from django.http import HttpResponse

    class UserInfoModelAdmin(admin.ModelAdmin):

        def 自定义(obj):         # obj 每行的一个对象

            return "%s-%s" % (obj.user,obj.email,)

        list_display = ('user','email',自定义)


    admin.site.register([models.UserInfo],UserInfoModelAdmin)
    admin.site.register(models.UserGroup,admin.ModelAdmin)


事例三: (自定义类的列, a 链接 )

    #导入from django.utils.safestring import mark_safe

    from django.contrib import admin
    from app01 import models
    from django.http import HttpResponse
    from django.utils.safestring import mark_safe

    class UserInfoModelAdmin(admin.ModelAdmin):

        def 自定义(obj):         # obj 每行的一个对象

            return mark_safe("<a href='http://www.baidu.com'>%s</a>" % (obj.user,))

        list_display = ('user','email',自定义)


    admin.site.register([models.UserInfo],UserInfoModelAdmin)
    admin.site.register(models.UserGroup,admin.ModelAdmin)

View Code

2. list_display_links，列表时，定制列可以点击跳转 (默认是第一列)

# 原先 <a> 在user上 现在在email上

from django.contrib import admin
from app01 import models
from django.http import HttpResponse
from django.utils.safestring import mark_safe

class UserInfoModelAdmin(admin.ModelAdmin):

    def 自定义(obj):         # obj 每行的一个对象

        return mark_safe("<a href='http://www.baidu.com'>%s</a>" % (obj.user,))

    list_display = ('user','email',自定义)
    list_display_links = ('email',)

admin.site.register(models.UserGroup,admin.ModelAdmin)

View Code

3. list_filter，列表时定制右侧快速筛选

        return mark_safe("<a href='http://www.baidu.com'>%s</a>" % (obj.user,))

    list_display = ('user','email',自定义)
    list_filter = ('user','email')


admin.site.register([models.UserInfo],UserInfoModelAdmin)
admin.site.register(models.UserGroup,admin.ModelAdmin)

View Code

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

5. 分页相关

# 分页，每页显示条数
    list_per_page = 100
 
# 分页，显示全部（真实数据<该值时，才会有显示全部）
    list_max_show_all = 200
 
# 分页插件
    paginator = Paginator

6. 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',)

7. search_fields 列表时模糊搜索的功能

# 根据user筛选

from django.contrib import admin
from app01 import models
from django.http import HttpResponse
from django.utils.safestring import mark_safe

    class UserInfo(models.Model):
        user = models.CharField(max_length=32)
        email = models.EmailField()
        date = models.DateTimeField(auto_now_add=True)

        def __str__(self):
            return self.user


# admin.py 

    from django.contrib import admin
    from app01 import models
