Django admin - 删除自引用字段的“添加另一个”按钮

Question

I have a Django project that includes a model class with an optional self-referential ForeignKey field. A partial snippet:

class Site(models.model):
    name = models.CharField(max_length=100)
    parent_site = models.ForeignKey('self', null=True, blank=True)

I'm using the Django admin site to create new objects. For this class' admin form I'd like to disable the " Add another... " button next to the parent_site field (ie when you're creating a new site, you can't open the popup to create another new site as the parent).

I can't remove has_add_permission from the user, as they need it to be in the current add view. I don't mind removing the function from both add and change views, but limiting removal to the add view would be helpful.

I haven't been able to work out how to use the Inline field classes to achieve this, or formfield_for_foreignkey , or a custom ModelForm . Anyone got a solution more elegant than using JavaScript on a customised form template?

Answer 1

no css hacks add to admin class:

max_num=0

or try this in admin.py ( for older django versions):

class MODEL_ADMIN(admin.ModelAdmin):
    class Media:
        css = {'all': ('css/no-addanother-button.css',)}
