Recommendation for updating a nested value inside a JSON field?

I’d like to update a JSON field by changing one of it’s nested fields.

In mongo, you do this like (http://docs.mongodb.org/manual/reference/operator/update/set/#up._S_set):

instance.update({
  json_field: {
    "$set": {
        "nested_field": "value"
     }
   }
})

Is there anything like that with Sequelize/Postgres? Right now all I can do is read/write the entire JSON field, it doesn’t seem like I can do deep updates to parts of it.

@tudor33sud What I am doing is something like:

Table.update(
{
  output: Sequelize.literal(`output || '["${JSON.stringify(obj)"]'`)
},
{
  where: { id }
}

Where obj is the object you are trying to append.

This will do an atomic append to the array.

This issue is old, instance.set() supports nested field updates through dot-syntax. It is an atomic operation on database level.
