What's this?

while_preventing_writes(enabled = true) public

Prevent writing to the database regardless of role.

In some cases you may want to prevent writes to the database even if you are on a database that can write. `while_preventing_writes` will prevent writes to the database for the duration of the block.

This method does not provide the same protection as a readonly user and is meant to be a safeguard against accidental writes.

See `READ_QUERY` for the queries that are blocked by this method.
