In my app, I receive a json from the client. This json can be anything since the user defines the keys and the values. In the backend I store it as string in the datastore.

Now i'm trying to override the MarshalJson / UnmarshalJson functions so that what I send / receive from the client is not a string but a json.

I can't figure out how to convert a string to json in go.

my structure

type ContextData string
type Iot struct {
Id              IotId       `json:"id,string" datastore:"-" goon:"id"`
Name            string   `json:"name"`
Context         ContextData  `json:"context" datastore:",noindex"` }

example of received data

{ 'id' : '',
  'name' '',
  'context': {
           'key1': value1,
           'key2': value2 }}

how i want to store this Context field in the datastore as a noindex string '{'key1':value1, 'key2':value2}' example of data i want to send

{ 'id' : '',
  'name' '',
  'context': {
           'key1': value1,
           'key2': value2 }}
