Question

我有一个上传滑块图片的模型，并将这些图片与一些文章绑定。

class SliderImages(models.Model):
    class Meta():
        db_table = 'slider'
    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='+')

然后在admin.py中写道：

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

它运作良好，没关系。但是图像文章的数量是有限的（3）。我希望管理员决定添加新文章的图片文章数量。我认为新模型看起来应该是这样的：

class SliderImages(models.Model):
    class Meta():
        db_table = 'slider'
    image = models.ImageField()
    article = models.ForeignKey(Article, related_name='+')

我想我应该使用inlines，但不知道如何

<强> models.py

from django.utils.translation import ugettext_lazy as _

class Slider(models.Model):
    title = models.CharField(_('title'), max_length=255, null=True, blank=True)

    class Meta():
        db_table = 'slider'


class SliderItems(models.Model):
    slider = models.ForeignKey(Slider, related_name='slider_items')
    image = models.ImageField()
    article = models.ForeignKey(Article, related_name='+')

<强> admin.py

from django.contrib import admin
from .models import Slider, SliderItems


class SliderItemsInline(admin.TabularInline):
    model = SliderItems

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


admin.site.register(Slider, SliderAdmin)
