Is there way to display historical records for all model instances using django-simple-history?

I am using django-simple-history for saving history of the objects. And it works fine. But I want to create a view in django admin that displays history records for all instances in model in one page.

For example I have a model

class TestModel(models.Model):
    title = models.CharField('title', max_length=100)
    history = HistoricalRecords()

and admin

class TestModelAdmin(SimpleHistoryAdmin):
    list_display = ['title']
admin.site.register(TestModel, TestModelAdmin)

And now I can see the history of each instance.

Not sure how I can solve this problem. May be there is a way to create custom views in admin site (without model), or maybe I should create another model?

What's the best way to display all history records (for all instances) in admin panel?

Use the through model of the TestModel.history as admin model:

class HistoricalTestModelAdmin(admin.ModelAdmin):
    list_display = ['title', 'history_object']


admin.site.register(TestModel.history.model, HistoricalTestModelAdmin)

The .history_object refers to the object for which we track the history. So in this case we can for example find the historical titles of your TestModel objects.
