Failed to decode field config - extra data in buffer

[ramesh-lingappan]

Hi,
Am trying to store a struct into datastore like below,

type Config struct {
Id int64 datastore:"id,noindex" goon:"id" json:"id"
Config map[string]float64 datastore:"config,noindex" json:"config,omitempty"
}

I have also impl PropertyLoaderSaver interface to convert the map into json string before saving to datastore, everything work fine with datastore, while fetching the json string is convert to back to map,

But when this entity is fetched from memcache am getting following error from goon.go file,

goon - goon.go:475 - goon: Failed to decode field config - extra data in buffer

Any help on how to fix this issue?

Note: Every First time fetch from datastore it works fine, only subsequent fetch (while it fetch from memcache) its throwing this error

Unfortunately PropertyLoadSaver isn't fully supported yet. You may be in luck soon though, as there is a PR for supporting it (#69). My current plan is to review that PR this weekend.

(I'm not 100% sure if that PR will make your code work, I hope it will, but I'm 100% sure that the current goon version doesn't support PropertyLoadSaver)

PS. Completely unrelated to your issue, but you don't need to store the Id property in the datastore like that, it's already part of the key.

Id int64 `datastore:"-" goon:"id" json:"id"`

Thanks, i did looked the PR, sounds promising , awaiting for it. And thanks for pointing out the issue, will ignore storing id.

PropertyLoadSaver is now supported, so this issue is resolved.
