write_portfolio.json

The JSON file of the “A tender pack of three lots” example. Three lots, each travelling as a file of its own, under the columns the document itself states — lot, day sent, total — sorted on the day, newest first. The cover sheet lays the same columns out for reading software that shows no pack.

JSON 388 lines

This file is a request: an application sends it over the network to the server, which creates the PDF and sends it back. It makes the same page as the Rust and Python versions of this example. A request names every file it uses, never its content; the call carries the request and the files together. A font the server already holds, such as DejaVuSans, is named with nothing attached. Send the request to the address the API page gives.

This request names files it does not carry: lot_a, lot_b, lot_c. Each one travels beside the request, in the same call, as a supplied part named exactly as the request names it here — the description says which name plays which role, so you name your files as you like. A request naming a file the call carries nothing of is refused.

What this example is for

Three firms answer a call for tenders, and what arrives is three sets of figures that have to stay apart and travel together. Each lot goes into this document as a file of its own, whole, in the shape it was sent in. What turns that from a bag of attachments into a pack somebody can work through is the rest: the document names the columns the files are shown under — the lot, the day it was sent, what it comes to — says what each file puts in each of them, and says the list is sorted on the day, newest first.
