python - 在 Django 管理中内联 : has no ForeignKey

Question

我有两个 Django 模型:

class Author(models.Model):
    user_email =  models.CharField(max_length=100, blank=True)
    display_name =  models.CharField(max_length=250)

class Photo(models.Model):
    author = models.ForeignKey(Author)
    image = ThumbnailImageField(upload_to='photos')

要获取内联照片，我在 admin.py 中有:

class PhotoInline(admin.StackedInline):
    model = Author

class AuthorAdmin(admin.ModelAdmin):
    list_display = ('display_name','user_email')
    inlines = [PhotoInline]

我收到一个错误:Exception at/admin/metainf/author/11/

<class 'metainf.models.Author'> has no ForeignKey to <class 'metainf.models.Author'>

为什么？

Answer 1

内联模型应该有一个指向父模型的外键。要在 Author 中内联获取 Photo，您的模型代码就可以了。但是您的管理员代码应该如下所示:

class PhotoInline(admin.StackedInline):
    model = Photo

class AuthorAdmin(admin.ModelAdmin):
    list_display = ('display_name','user_email')
    inlines = [PhotoInline]
