+  You'll see two patterns in older code: dynamic finders like `findOneByEmail(value)` and explicit `where=` finders. The dynamic finders parameterize the value automatically — Wheels turns `findOneByEmail(emailVal)` into a prepared statement with a bound parameter. Writing `findOne(where="email = '#emailVal#'")` would interpolate the user input straight into SQL, which is a SQL injection vulnerability. Stick to dynamic finders for single-column lookups; reach for `where=` only when you need an operator other than equality, and always use `cfqueryparam`-style binding via the [chainable query builder](/v4-0-0-snapshot/basics/models-and-the-orm/#chainable-query-builder).

 ## Troubleshooting
 
 **"Model spec fails with `cannot find Post.cfc`."** The test runner boots a fresh schema from `tests/populate.cfm`, which you haven't set up yet. See [Fixtures & Test Data](/v4-0-0-snapshot/testing/fixtures-and-test-data/) for the standard `populate.cfm` that mirrors your development schema into the test database.
 
-**"Browser spec hangs for thirty seconds, then times out."** Playwright isn't installed. Run `wheels browser install` — it downloads ~370MB and prints a progress bar. Once it completes, re-run the spec. If it still hangs, check that `this.browserTestSkipped` isn't incorrectly set; the guard clause should short-circuit when the JARs are missing, not when they're present.
