在管理页面中查看相册中的照片

Question

我希望能够在管理页面中查看我相册中的所有照片。

我是Django的新手，所以我不确定如何创建一个功能，点击相册标题后会显示所有照片。我相信我必须对AlbumAdmin课做些什么，但我不确定那会是什么。专辑和图片之间存在一对多的关系。当我点击并进入特定的专辑页面时，我只想抓住与该专辑相关的所有图片

当我点击相册时，目前没有显示任何内容。在我的数据库中，实际上有相册中的图片。

应用程序/ models.py：

from django.db import models
from django.contrib import admin
from PIL import Image
from Boothie.settings import MEDIA_ROOT
from django.conf import settings
import os.path
import re
from django.utils.safestring import mark_safe


class Album(models.Model):
    title = models.CharField(max_length=50, unique=True)

    def __str__(self):
        return self.title

    def images(self):
        lst = [x.photo for x in self.photo_set.all()]
        return lst

    def save(self, *args, **kwargs):
        rgx = re.search(r'.*\w', self.title)
        self.title = rgx.group(0).replace(" ", "_")
        super(Album, self).save(*args, **kwargs)


class AlbumAdmin(admin.ModelAdmin):
    search_fields = ["title"]
    list_display = ["title"]


def upload_path(self, filename):
        title = self.album.title
        if " " in title:
            title.replace(" ", "_")
        return os.path.join(title, filename)


class Photo(models.Model):
    title = models.CharField(max_length=50, blank=True)
    album = models.ForeignKey(Album)
    photo = models.ImageField(upload_to=upload_path)
    upload = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.title

    def size(self):
        return "%s x %s" % (self.photo.width, self.photo.height)

    def thumbnail(self):
        thumbnail_html = "<a href=\"{0}{1}\"><img border=\"0\" alt=\"\" src=\"{2}{3}\" height=\"80\" /></a>".format(settings.MEDIA_URL, self.photo.name, settings.MEDIA_URL, self.photo.name)
        return thumbnail_html

    thumbnail.allow_tags = True

    def photo_name(self):
        return os.path.basename(MEDIA_ROOT + "/" + self.photo.name)

    def photo_display(photo):
        return mark_safe('<a href="%s">%s</a>' % (photo.photo.url, os.path.split(photo.photo.name)[1]))

class PhotoAdmin(admin.ModelAdmin):
    search_fields = ["title", "photo"]
    list_display = ["photo_display", "thumbnail", "title", "album", "size"]
    list_filter = ["album"]

Answer 1

此功能由inline admin classes提供。

class PhotoAdmin(admin.TabularInline):
    model = Photo

class AlbumAdmin(admin.ModelAdmin):
    search_fields = ["title"]
    list_display = ["title"]
    model = Album
    inlines = [PhotoAdmin]

请注意，这些类应位于admin.py文件中，而不是models.py。
