How to use cache?

Hello,

thanks you for this simple and straightforward package!

I'm successfully using in one of my current projects. The DB interface works perfectly fine, however I have difficulties getting the caching layer to work.

I have written a little middleware that injects the CacheHandler.

func CacheMiddleware(next http.Handler) http.Handler {
	return firestorm.CacheHandler(next.ServeHTTP)
}

and adding it to my router (go-chi):

r.Use(db.CacheMiddleware)
r.Get("/", indexHandler)

From each of my HTTP handlers, I'm then passing the context onto the db functions:

func countryHandler(w http.ResponseWriter, r *http.Request) {
    ...
	countryData, err := LoadCountryData(r.Context())
	if err != nil {
		log.Printf("Failed to load  data: %s", err)
		http.Error(w, "Internal Server Error", 500)
		return
	}
    ...
}

// var Client *firestorm.FSClient was initialized somewhere else
func LoadCountryData(ctx context.Context) (*types.Country, error) {
	var c = &types.Country{ID: slug}
	_, err := Client.NewRequest().SetLoadPaths(firestorm.AllEntities).GetEntities(ctx, c)()
	if IsNotFoundError(err) {
		return nil, nil
	} else if err != nil {
		return nil, err
	}

	return c, nil
}

Nevertheless, I still get the message "Warning. Consider adding the CacheHandler middleware for the session cache to work" and subsequent database calls don't seem to be faster.

Am I using the cache (in)correctly? Is there a way I can verify its behavior?

panic: reflect: call of reflect.Value.NumField on zero Value

Hello 👋

Thank you for an excellent library! I've had some issues with panic: reflect: call of reflect.Value.NumField on zero Value.

Guessing it's caused by passing empty/nilled fields? Any tips to how I can fix it?

Not for Firestore in Datastore mode

The docs should mention that the library does not support Firestore in Datastore mode.

go-firestorm User Group

The link for go-firestorm User Group does not work, or rather I do not have access to it. Is it meant to be non-public or is something wrong?

Thanks again for an awesome project, @jschoedt!
