英文:
Add multiple instances of a model with some shared fields at once
问题
我正在尝试想出一种方法，允许用户在Django管理界面一次性添加多个特定模型的实例，但其中一些字段在它们之间共享。
示例模型：
class Something(models.Model):
ref = models.ForeignKey(to="AnotherModel", on_delete=models.CASCADE)
name = models.CharField(max_length=255)
is_active = models.BooleanField(default=True)
我想要实现的是在Django管理界面中有一个页面，用户可以在其中只定义一次ref字段的值，然后添加和填充尽他想要的name和is_active字段，然后点击保存按钮，ref字段会自动重新使用，以创建与用户创建的name和is_active字段一样多的Something实例。
我知道Django的StackedInline和TabularInline，但我无法使用它们来实现上述功能。
谢谢。

I'm trying to come up with a way of allowing a user to add multiple instances of a specific model at once in Django Admin, but with some fields being shared between them.
Example model:
class Something(models.Model):
ref = models.ForeignKey(to="AnotherModel", on_delete=models.CASCADE)
name = models.CharField(max_length=255)
is_active = models.BooleanField(default=True)
What I am trying to achieve is to have a page in Django Admin where the user would define the value of ref field only once, then add and populate as many name and is_active fields as he wants, press the Save button and the ref field would get automatically re-used to create as many Something instances as the user created with the name and is_active fields.
I know of Django's StackedInLine and TabularInLine, but I am not able to produce the above mentioned functionality with them, at all.
Thank you

得分: 3
class SomethingInline(admin.TabularInline):
model = Something
extra = 1
class AnotherModelAdmin(admin.ModelAdmin):
inlines = [SomethingInline]
这样你可以创建另一个模型实例并添加多个Something模型的内联项目。
英文:
class SomethingInline(admin.TabularInline):
model = Something
extra = 1
class AnotherModelAdmin(admin.ModelAddmin):
inlines = [SomethingInline]
this way you can create another model instance and add multiple inline items of Something model.
