如何从Django恢复对象访问评论和用户

Question

How can I access comments and user from an reversion object?

to create a reversion I use this

with transaction.atomic():
    with reversion.create_revision():
        reversion.set_user(request.user)
        reversion.set_comment("update event")
        form.save()

Now I want to access the user and comment ... I tried:

import reversion
revs = reversion.models.Version.objects.all()
rev1 = revs[0]
dir(rev1)
['DoesNotExist', 'MultipleObjectsReturned', '__class__', '__delattr__',
'__dict__', '__doc__', '__eq__', '__format__', '__getattribute__',
'__hash__', '__init__', u'__module__', '__ne__', '__new__', '__reduce__',

Answer 1

Check the revision attribute of the Version object. Notice that the usual way to get a list of Version s for a specific object obj is to use the reversion.get_for_object(obj) method.

Also, I've written a rather comprehensive Post about reversion (and other similar solutions) @ http://spapas.github.io/2015/01/21/django-model-auditing/

Answer 2

Create a function in your views as below

from reversion.models import Version
import json

def history_list(request)
 history_list = Version.objects.all().oreder_by('revision_date_created')
 data = []
 for i in history_list:
  data.append({
     'user': str(i.revision.user),
     'comment': i.revision.comment
  })
print(data)

Instead of printing in your terminal if you would like to have a route where it should print user and comment as json add the additional to above function

from django.http import HttpRespose
...............
...............
data_ser = json.dumps(data)
return HttpResponse(data_ser, content_type="application/json")
