django 1.5 admin inline extra

Question

我有一些带有大量内联的模型.因为并非所有对象都需要我声明内联模型,extra = 0所以add +内联上出现一个小的.

但是,这似乎不再适用于django 1.5.如果extra = 0设置,则内联不再可编辑.

有没有办法将1.4行为变为1.5？

示例代码:

class ModelInline(admin.StackedInline):
    model = MyModel
    extra = 0

class OtherModelAdmin(admin.ModelAdmin)
    inlines = [ModelInline]

admin.site.register(OtherModel, OtherModelAdmin)

编辑(一些屏幕):

Django 1.4:

Django 1.5:

Answer 1

这已经发生过了.

The new javascript made this impossible because the "Add Another" button 
was controlled by max_num, and ignored a value of 0.
The javascript ignored a value of 0 because max_num has a default value of 0, 
and all the code using it had taken to equating max_num = 0 with being "off". 
So you can't actually have a maximum of 0. It's not possible.

Gabrial Hurley创建了一个补丁,用于恢复所需的行为而不会破坏任何其他内容.这是3年前,我不知道它是否仍然适用于Django 1.5.试一试 :)
