I use [https://github.com/etianen/django-reversion django-reversion]
library in one of my projects. In admin it uses `ModelAdmin`'s change
message generated by `construct_change_message` method as revision
comment. Besides admin I also need to generate same change message on
object creation / editing on frontend part of a site.
Using `construct_change_message` outside of admin is now possible like
that:
{{{#!python
from django.contrib.admin import AdminSite
from enterprises.admin import EnterpriseAdmin
comment = EnterpriseAdmin(enterprise,
AdminSite).construct_change_message(request, form, formsets, create)
}}}
`enterprise` is either created or edited model, `create` - boolean
variable (`True` when create and `False` otherwise).
I think it's not clean to refer to admin from frontend like that.
As a suggestion, we can move the method outside of a class. It does not
use `self` also.
Another option is to make this method static, but this will just reduce a
bit of code, and problem of referring from frontend to admin will still
present.
