# `ActionController::Live` vs. `prevent_writes`

WIP trying to create a reproducible test case for an issue we're seeing in our

environment, when combining `ActionController::Live` with

`ActiveRecord::Base.connected_to`.

Run using `docker compose up`. Probably needs a recent Docker version.

The main test is in `test.bash`, which should expose the following behaviour:

- First it issues a GET to the `/ping` endpoint, which works.

- Then it GETs a `ActionController::Live` streaming endpoint and disconnects early.

- Then it issues another GET to the `/ping` endpoint again, which fails with the following error:

  `No connection pool for 'ActiveRecord::Base' found for the 'reading' role.`

Most of the files in this repository are just Rails scaffolding, the main

interesting files are the ones in `app/controllers`.
