我在django上有一个新项目,其中我使用Grappelli和filebrowser,我已经扩展了User以获得与之相关的UserProfile,我的问题是,如何修改我的代码以便能够在上传个人资料图片的用户的UserProfile信息,并将其显示在用户列表中?

这是我的代码,我在管理员身上看不到任何图片!

Admin.py

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.models import User
from models import UserProfile

class UserProfileInline(admin.StackedInline):
     model = UserProfile
     verbose_name_plural = 'User Profile'
     list_display = ('city', 'tel', 'description', 'image_thumbnail',)

class MyUserAdmin(UserAdmin):
    list_display = ('username','email','first_name','last_name','date_joined',
        'last_login','is_staff', 'is_active',)
    inlines = [ UserProfileInline ]


admin.site.unregister(User)
admin.site.register(User, MyUserAdmin)

Models.py

from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.utils.translation import ugettext_lazy as _
from apps.common.utils.abstract_models import BaseModel
from apps.common.utils.model_utils import unique_slugify
from filebrowser.base import FileObject
from django.conf import settings

class UserProfile(BaseModel):
    user = models.OneToOneField(User, related_name="profile")
    city = models.CharField(_("City"), max_length=200)
    tel = models.CharField(_("Phone Number"), max_length=50, 
    help_text=_("(Area Code) (Your phone number)"))
    description = models.TextField(null=True, blank=True, 
        help_text = _("Small description about yourself."))
    photo = models.ImageField(max_length=255, upload_to="profiles/", 
        null=True, blank=True, default="img/default_profile_image.png")

    def image_thumbnail(self):
        if self.photo:
             return u'<img src="%s" width="80" height="80" />' % self.photo.version(ADMIN_THUMBNAIL).url
        return u'<img src="/site_media/%s" width="80" height="80" />' % settings.DEFAULT_PROFILE_IMAGE

     image_thumbnail.allow_tags = True

    def __unicode__(self):
        if self.user.first_name or self.user.last_name:
            return "%s %s" % (self.user.first_name, self.user.last_name)
        else:
            return self.user.username

嗯,我得到了它,首先我想在管理员的用户模型的UserProfile内联部分以及管理员的更改列表中显示所选择的图像所以我是什么

我将models.ImageField更改为用户个人资料的model.py上的sorl ImageField

from sorl.thumbnail import ImageField
class UserProfile(BaseModel):
[...]
    photo = ImageField(max_length=255, upload_to="profiles/", 
        null=True, blank=True, default="img/default_profile_image.png")

然后在管理员上,我所要做的就是在UserProfileInline类上添加sorl的AdminImageMixin,如下所示:

from sorl.thumbnail.admin import AdminImageMixin

class UserProfileInline(AdminImageMixin, admin.StackedInline):
    model = UserProfile
    verbose_name_plural = 'User Profile'

这样,您就可以在该用户的管理员的UserProfile Inline部分获得一个图像,现在是change_list。

对于更改列表,我必须在UserAdmin类的admin.py文件中执行一个小的可调用函数,这是我所做的,使用sorl的get_thumbnail:

from sorl.thumbnail import get_thumbnail

class MyUserAdmin(UserAdmin):

    def image_thumbnail(self, obj):
        im = get_thumbnail(obj.get_profile().photo, '80x80', quality=99)
        return u"<img src='/site_media/%s' />" % im
    image_thumbnail.allow_tags = True

    list_display = ('image_thumbnail', 'username','email','first_name','last_name','date_joined',
    'last_login','is_staff', 'is_active',)

现在我有一个用户个人资料的更改列表图像,也有UserProfile内联部分。

希望这适用于所有人...并且感谢@pastylegs以获得您之前的答案!

list_display需要是可调用的:

https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_display

所以你可以这样做:

class UserProfileInline(admin.StackedInline):

    def image_thumbnail(self, obj):
        return obj.image_thumbnail()
    image_thumbnail.short_description = 'Thumbnail'

    model = UserProfile
    verbose_name_plural = 'User Profile'
    list_display = ('city', 'tel', 'description', 'image_thumbnail',)
