django - 如何在单个 django 模型条目中包含数据行？

Question

我在多个 django 网站上工作，并且在使我的项目对客户看起来不错方面受到限制。

例如，在同一个应用程序中，我有两个模型图像和图像库。如果只有一个画廊的管理员条目和一张图像表，那就更好了。

Answer 1

这正是InlineModelAdmin它的用途。采取了这样的models.py：

class Gallery(models.Model):
   name = models.CharField(max_length=100)

class Image(models.Model):
   image = models.ImageField()
   gallery = models.ForeignKey(Gallery)

你像这样创建一个 admin.py 并且只为 Gallery 注册一个管理类：

class ImageInline(admin.TabularInline):
   model = Image

class GalleryAdmin(admin.ModelAdmin):
    inlines = [ImageInline]

admin.site.register(Gallery, GalleryAdmin)

感谢 Dirk 的帮助，这是我的解决方案。

from django.db import models

PHOTO_PATH = 'media_gallery'

class Gallerys(models.Model):
    title = models.CharField(max_length=30, help_text='Title of the image maximum 30 characters.')
    slug = models.SlugField(unique_for_date='date', help_text='This is automatic, used in the URL.')
    date = models.DateTimeField()

    class Meta:
        verbose_name_plural = "Image Galleries"
        ordering = ('-date',)

    def __unicode__(self):
        return self.title

class Images(models.Model):
    title = models.CharField(max_length=30, help_text='Title of the image maximum 30 characters.')
    content = models.FileField(upload_to=PHOTO_PATH,blank=False, help_text='Ensure the image size is small and it\'s aspect ratio is 16:9.')
    gallery = models.ForeignKey(Gallerys)
    date = models.DateTimeField()

    class Meta:
        verbose_name_plural = "Images"
        ordering = ('-date',)

    def __unicode__(self):
        return self.title

import models
from django.contrib import admin

class ImageInline(admin.TabularInline):
   model = Images

class GallerysAdmin(admin.ModelAdmin):
    list_display = ('title', 'date', 'slug')
    inlines = [ImageInline]

admin.site.register(models.Gallerys,GallerysAdmin)
