Provide decorators to easily mark functions/methods as list_display items or admin actions

[Matt Harasymczuk]

How about changing:

model_method.allow_tags = True
model_method.short_description = _('Model Method')

into:

@options(allow_tags=True, short_description=_('Model Method'))

or:

@allow_tags
@short_desctiption(_('Model Method'))

?

I've released a simple app for this some time ago: ​https://github.com/kmike/django-admin-decorators

#25134 is a duplicate with some discussion.

[Curtis Maloney]

In discussion with someone this morning, I whipped up this

class admin_list(object):
    def __init__(self, boolean=None, order_field=None, allow_tags=None, short_description=None):
        self.boolean = boolean
        self.order_field = order_field
        self.allow_tags = allow_tags
        self.short_description=short_description

    def __call__(self, attr):
        if self.boolean is not None:
            attr.boolean = self.boolean
        if self.order_field is not None:
            attr.admin_order_field = self.order_field
        if self.allow_tags is not None:
            attr.allow_tags = self.allow_tags
        if self.short_description is not None:
            attr.short_description = short_description
        return attr

Then asked if anyone thought it'd be useful, and @timgraham pointed me to this ticket. I'll dump this here for now... feel free to bike shed the names, or I'll make a PR if you like.

Also, keep in mind allow_tags is deprecated #25135.
