The only thing that is different is the name of the template. How about:

```python
            if crash_age < datetime.timedelta(days=1):
                tmpl = 'crashstats/report_index_pending.html'
            else:
                tmpl = 'crashstats/report_index_not_found.html'
                         
            return render(request, tmpl, context)
                             
```
