Adding buyer-to-seller chat to an order page

After nested chat service classes were added, the autoload check was run against the app. It completed successfully and reported no constant loading problems.

What worked
The new service layout loaded cleanly under the existing autoloader with no extra configuration.

Validating Rails constant autoloading

The Rails Zeitwerk check validated naming and autoloading for the newly added controllers, models, and service classes. Repeated checks completed successfully.

What worked
A single framework task caught an important class of integration errors without needing to exercise every runtime path.

Validating application autoload structure

Relied on Rails' Zeitwerk integration to validate the new service namespace and exception classes. The final autoload check passed after constants and files were aligned.

What worked
Strict file-to-constant mapping exposed structural mistakes that could otherwise have appeared only under eager loading in production.
What got in the way
The DocuSign brand capitalization conflicted with default inflection, and exception classes initially lived in files that did not match Zeitwerk's expected paths.

Checking Rails constant autoloading

Ran the Rails autoload consistency check after adding controllers, models, and namespaced service classes; the check passed.

Validating application autoloading and class naming

Ran the framework-provided Zeitwerk check repeatedly after adding namespaced services and controllers. It successfully eager-loaded the new classes and reported no naming or loading problems.

What worked
A single command provided a fast, database-independent check of file naming, namespaces, and constant loading.

Checking Rails autoloading and eager loading

Ran the Rails Zeitwerk check repeatedly after adding controllers, models, mailers, workers, and initializers. Every completed check reported that application eager loading was valid.

What worked
It provided a quick database-independent verification that constants, filenames, and autoload paths remained coherent.

Checking application autoloading after implementation

Explicitly ran the Rails-integrated Zeitwerk check after adding models, controllers, and query objects. The check passed, providing a focused validation of application loading.

Loading search service code

Relied on the autoloader for a search namespace that mixed a module file with a same-named directory of clients and indexers. After the layout and reload hook were fixed, the explicit check passed.

What worked
The dedicated check confirmed the final search namespace loaded. Keeping the client wrapper name distinct from the engine client avoided a constant clash.
What got in the way
A module file and directory sharing one name was an autoload conflict, and development reload could keep a stale client unless configuration ran on prepare. That cost extra layout and initializer work.
