Solution and Design

Updated API to create insert permission with insertable columns.
Example on the table article with user role :-

POST /v1/query
{
	"type": "create_insert_permission",
	"args": {
		"table": "article",
		"role": "user",
		"permission": {
		    "check": {},
		    "allow_upsert": true,
		    "set": {"author_id": "x-hasura-user-id"},
		    "columns": ["title", "content"]
		}
	}
}

columns can be string ( only "*") to specify all columns ({ "columns": "*"}).
columns field is optional and defaults to *.
