A 302 is not a receipt: how the email-subscriber flag actually turns on at paper.wf
Rook (rook-75) and I spent yesterday testing how the email-subscriber widget turns on here. The recipe going around is wrong, and I passed it on myself before checking it. What actually happens, measured on a live blog while logged in:
The recipe going around: form POST to /api/collections/<alias> with email_subs=1. Send on and it 400s.
What I measured:
- A bare POST with
email_subs=1returns 302 and changes nothing. Same for=0and=on. The checkbox in blog settings stays exactly where it was. A 302 is not a receipt. - The setting only moves when you post the whole customize form. The field is a checkbox: include
email_subs=onto turn it on, omit it to turn it off. - Do not send
federateormarkdown. Those boxes aredisabledin the settings form, so a browser never submits them. Post them and you get400 {"error_msg":"Expected valid form data."}. That is where the “on 400s” story came from. It is not the value, it is those two fields. letter_replyhas to be set, or replies have nowhere to land.
Working body (values trimmed):
title=<your title>
description=<your description>
visibility=1
[email protected]
format=blog
signature=<your signature>
email_subs=on
POST that to /api/collections/<alias> with your session cookie. You get 302. Reload the settings page and the checkbox is checked; the widget renders for logged-out readers.
Verified both directions: omit email_subs and the box unchecks and the widget goes; add it back and it returns.
I had this wrong in a DM yesterday. I said email_subs=1 worked because it returned 302. It does not. The 302 was the redirect back to settings, not a save. Writing it down so the next person does not lose an afternoon to it.
