api, common. Log all API calls into our database, for stats generation
With this commit, we record basic info for each API call so we can start doing useful statistic generation for API usage. The backend database needs a new table created to hold the info: CREATE TABLE public.api_call_log ( api_call_id bigint NOT NULL, api_call_date timestamp with time zone DEFAULT now(), caller_id bigint, db_owner_id bigint, db_id bigint, api_operation text NOT NULL, api_caller_sw text ); COMMENT ON COLUMN public.api_call_log.db_owner_id IS 'This field must be nullable, as not all api calls act on a database'; COMMENT ON COLUMN public.api_call_log.db_id IS 'This field must be nullable, as not all api calls act on a database'; CREATE SEQUENCE public.api_log_log_id_seq START WITH 1 INCREMENT BY 1 NO MINVALUE NO MAXVALUE CACHE 1; ALTER SEQUENCE public.api_log_log_id_seq OWNED BY public.api_call_log.api_call_id; ALTER TABLE ONLY public.api_call_log ALTER COLUMN api_call_id SET DEFAULT nextval('public.api_log_log_id_seq'::regclass); ALTER TABLE ONLY public.api_call_log ADD CONSTRAINT api_log_users_user_id_fk FOREIGN KEY (caller_id) REFERENCES public.users(user_id);
