Here's an example I can imitate: https://github.com/simonw/datasette/blob/7ac4936cec87f5a591e5d2680f0acefc3d35a705/tests/test_plugins.py#L588-L596,"{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",644309017,datasette.add_message() doesn't work inside plugins,

For example, this code in a plugin:
```python
        return Response.html(
            await datasette.render_template(
                ""write.html"",
                {""databases"": databases, ""sql"": request.args.get(""sql"") or """"},
                request=request,
            )
        )
```
This won't display messages. The reason is that the messages are made available to the template context in the `BaseView.render()` method here:

I may still complete this overall goal (registering internal views with `register_routes()`) as part of Datasette 0.45 but it would be OK if it slipped to a later release.

Here's where I added that custom `dispatch_request()` method - it was to implement flash messaging in #790: https://github.com/simonw/datasette/blame/1a5b7d318fa923edfcefd3df8f64dae2e9c49d3f/datasette/views/base.py#L85

If I want this to be made available to `register_routes()` views as well, I'm going to have to move the logic somewhere else. In particular I need to make sure that the `request` object is created once and used throughout the whole request cycle.

Currently `register_routes()` view functions get their own separate request object which is created here:

https://github.com/simonw/datasette/blob/1a5b7d318fa923edfcefd3df8f64dae2e9c49d3f/datasette/app.py#L1057-L1068

So I'm going to have to refactor this quite a bit to get that shared request object which can be passed both to `register_routes` views and to my various `BaseView` subclasses.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",644309017,datasette.add_message() doesn't work inside plugins,
