使用特定对象绑定每个模型字段

Question

我有一个文章模型，我写了一些文章。另外，在我的网站中，我有一个带有3个图像的滑块。我创建了一个模型。

class SliderImages(models.Model):
    class Meta():
        db_table = 'slider'
    image_1 = models.ImageField()
    image_2 = models.ImageField()
    image_3 = models.ImageField()

如何用一些文章绑定每个图像？在django admin中，我想上传图片并将其绑定到一些文章，然后在滑块中每个图片都会有一个指向某篇文章的链接

理想情况（一张图片一张）

代码： 机型：

class Slider(models.Model):
    article = models.ManyToManyField(Article)

class SliderImages(models.Model):
    slider = models.ForeignKey(Slider, null = True, related_name= '+')
    article = models.ForeignKey(Article, null = True, related_name= '+')
    image = models.ImageField()

    class Meta():
        db_table = 'slider'

并在admin.py中：

class SliderInline(admin.TabularInline):
    model = SliderImages
    max_num = 3

class SliderAdmin(admin.ModelAdmin):
    inlines = [SliderInline,]

admin.site.register(Slider, SliderAdmin)

Answer 1

只需添加一个ForeignKey与您要绑定的模型对象，并将正常的Django绑定设置为该文章对象：

class SliderImages(models.Model):
    class Meta():
        db_table = 'slider'
    article = models.ManyToManyField(Article)
    image_1 = models.ImageField()
    image_2 = models.ImageField()
    image_3 = models.ImageField()

Answer 2

只需在文章中添加三个外键：

class SliderImages(models.Model):
    class Meta:
        db_table = 'slider'
    article = models.ManyToManyField(Article)
    image_1 = models.ImageField()
    image_2 = models.ImageField()
    image_3 = models.ImageField()
    article_1 = models.ForeignKey(Article, related_name='+')
    article_2 = models.ForeignKey(Article, related_name='+')
    article_3 = models.ForeignKey(Article, related_name='+')

然后使用admin.py中的字段集将image_N / article_N放在一行中：

class SliderImagesAdmin(admin.ModelAdmin):
    fieldsets = (
        (None, {
            'fields': ('article', ('image_1', 'article_1'),
                                  ('image_2', 'article_2'),
                                  ('image_3', 'article_3'),)
        }),
    )    
admin.site.register(SliderImages, SliderImagesAdmin)

如果您想为每篇文章分配一些图像，那么：

class SliderImages(models.Model):

  article = models.ForeignKey(Article)
  image = models.ImageField()

  class Meta():
    db_table = 'slider'

然后在管理员中，您将SliderImages设为内联文章，请参阅https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.StackedInline

class SliderInline(admin.TabularInline):
    model = SliderImages
    max_num = 3

class ArticleAdmin(admin.ModelAdmin):
    inlines = [
       SliderInline,
    ]
