So I think the fix is to move the "select_templates": select_templates context setting bit to here instead:

https://github.com/simonw/datasette/blob/e89b0ef2f9ae89eb3bde83b694f21452ea4858da/datasette/views/base.py#L75-L83

Here's why: the BaseView.render() method is running jinja_env.select_template() now here:

https://github.com/simonw/datasette/blob/e89b0ef2f9ae89eb3bde83b694f21452ea4858da/datasette/views/base.py#L75-L88

Which means this logic is always called with a template, not a list of strings:

https://github.com/simonw/datasette/blob/e89b0ef2f9ae89eb3bde83b694f21452ea4858da/datasette/app.py#L555-L571

git bisect start master 0.34 git bisect run python check_templates_considered.py

Just need the one checking script to run with bisect this time:

check_templates_considered.py

```python import asyncio import pathlib from datasette.app import Datasette import httpx

async def run_check(): ds = Datasette([]) async with httpx.AsyncClient(app=ds.app()) as client: response = await client.get("http://localhost/") assert 200 == response.status_code assert "Templates considered" in response.text

if name == "main": loop = asyncio.get_event_loop() loop.run_until_complete(run_check()) ```

I'm going to debug this using git bisect run - the same technique I used in #716 - https://github.com/simonw/datasette/issues/716#issuecomment-609453886
