Support for 'extra_response_fields'. 'on_posting' and 'on_posting_<resource>' events are raised before the documents are inserted into the database. This allows callback functions to arbitrarily edit/update the documents being stored. .. versionchanged:: 0.0.6 Support for bulk inserts. Please note: validation constraints are checked against the database, and not between the payload documents themselves. This causes an interesting corner case: in the event of a multiple documents payload where two or more documents carry the same value for a field where the 'unique' constraint is set, the payload will validate successfully, as there are no duplicates in the database (yet). If this is an issue, the client can always send the documents once at a time for insertion, or validate locally before submitting the payload to the API. .. versionchanged:: 0.0.5 Support for 'application/json' Content-Type .

If validation passes the document is inserted and ID_FIELD, LAST_UPDATED and DATE_CREATED along with a link to the document are returned. If validation fails, a list of validation issues is returned. :param resource: name of the resource involved. :param payl: alternative payload. When calling post() from your own code you can provide an alternative payload. This can be useful, for example, when you have a callback function hooked to a certain endpoint, and want to perform additional post() calls from there. Please be advised that in order to successfully use this option, a request context must be available.
