Ok, so I should just redirect back to the new_proof_url endpoint, fair enough
yeah. redirecting is perfect. it doesn’t have to redirect to new it could also go to the user’s profile page or settings page or something like that as long as the flash notice tells the user something actionable. whatever makes the most sense. i’m not really sure. no opinions.
the logged-in user is the discourse user that is making the proof
absolutely. yes. it looked like here we’re only checking if it’s the correct user on create and i’d argue we should also do it on new. there’s no sense in trying to save a proof that we know will fail.
The code I pushed is not the latest. I rewrote the create method, removing the check for the username param as it should not be necessary anymore (as the proof_valid? check will fail).
The new method is just a placeholder for Discourse routing logic, it will never be called and it needs to allow non-logged-in requests to allow the user to log in if they logged off previously
EDIT: this is the new code I just pushed (still not very polished, I pushed it just to let you see it).
I am having issues updating the proof custom field. The first time I put a JSON object in it, it works, but any attempt to change the value of the custom field fails. This is the code:
def create
kb_username = params.fetch('kb_username')
sig_hash = params.fetch('sig_hash')
proof = Proof.new(current_user.username, kb_username, sig_hash)
unless proof.valid?
raise Discourse::InvalidParameters, I18n.t('keybase_proofs.invalid_proof')
end
proofs = current_user.custom_fields['keybase_proofs'] || {}
# Override the signature because the old one might have been
# revoked and not yet updated on our side.
proofs[kb_username] = proof.signature
current_user.custom_fields['keybase_proofs'] = proofs
current_user.save
render json: success_json
end
the first time this code is called, it adds the proofs to the custom field named "keybase_proofs". If I call it again, it doesn’t update the custom field.
Some more information: if I change the type of the custom field to a string, it works correctly.
Is not returning a hash, so on the first time it works because you coalesce it to an empty Hash. But it fails on subsequent tries because it’s returning something else.
Unfortunately not. Since I am learning how everything works together, my code is almost always in a very sad shape, not really worth pushing. But the code that is in GitHub shows exactly the same issue (but I didn’t push the tests).
In the latest version of the code, which I have locally, I got rid of the JSON type and I am just using serialized JSON strings instead, and it is now working fine.
This is not the case. When I say that “it fails”, I mean “it fails to update” the field. So the first time the code runs, it saves the custom field correctly (I can also retrieve it, I use the data in the profile page and in the check proof endpoint). The second time I run the code (ie, if I add another Keybase identity to the same Discourse user), the custom field is not updated, it keeps only the first signature I added.
In case you’re curious and you want to debug the issue, I’ll create a branch with the original code and tests (that were failing) so you can investigate
Unfortunately I don’t know how to do it for this codebase using VS Code do you have any advice on an alternative editor? RubyMine?
You can add a byebug to any line in the controller, and when that line is hit the console where you started the webserver (the one you run bin/unicorn -x) will stop and allow you to inspect the variables.
The debugger confirms what I saw with previous testing: the JSON is stored the first time, and any attempt to change it later gets silently ignored. Anyway, for now I have fixed it by manually parsing/encoding the JSON string in the custom field.
It should mostly work. There are a few things to fix before it is “shippable”:
The “new proof” UI needs some CSS love. It should also show an error if the logged in user is not the one for which the proof is requested.
The config endpoint /keybase-proofs/config needs a couple of SVG logos, but I don’t know where to get them from. Ideas? @kb_xgess, do they need to be SVG? Do you need both the black&white and the colored one?
redirect-after-login doesn’t work currently. @techAPJ is investigating, might be a bug in Discourse core or (more likely?) a bug somewhere in the plugin.
Some notes on code quality:
I didn’t write frontend tests. I think I’ve got the gist of how to write tests for components, but I didn’t want to spend more time figuring out how to mock requests and so on.
proof_controller.rb has a very ugly pic_url method, needed because I couldn’t make the call to the keybase API from the client because of CORS. I guess it can be moved to somewhere else or someone can figure out how to fetch the information from the client side.
I didn’t run any linter/formatter on the code. Should I?
Ich schaue mir gerade etwas von deinem Code an. Großartige Fortschritte! Kurze Frage zu meta.discourse.org: Läuft dort eine andere Codebasis? Können wir deinen Code darauf bereitstellen? Ich frage, weil ein Teil des Back-and-Forth-Protokolls darin besteht, dass Keybase Discourse abfragt, um den gehosteten Nachweis zu prüfen. Wenn er dort nicht vorhanden ist, wird alles fehlschlagen. Daher könnte es für dich einfacher sein, auf einem öffentlichen Server zu iterieren, der weniger produktionsreif ist. Falls das Sinn ergibt: Vielleicht eine Staging- oder eine gehostete Entwicklungsumgebung. Oder falls du ein Konto bei ngrok hast, können wir eine statische URL einrichten, die immer zu deinem lokalen Host weiterleitet, der nur dann aktiv ist, wenn du es möchtest (ganz von deiner Seite aus). Wenn du auf meta.discourse.org die benötigte Flexibilität hast, kann ich das für diese Seite mit den Konfigurationen in deinem Code und einigen anderen Standardwerten aktivieren.
Noch eine weitere Frage zu den SVGs: SVGs sind ideal, da wir tatsächlich einige PNGs in verschiedenen Größen für die mobile App, die Desktop-App und die Website benötigen. Es ist wahrscheinlich für alle einfacher, wenn wir sie alle aus denselben Ausgangsdaten rendern können.
Das ist enttäuschend. Ist das zwingend notwendig, @kb_xgess? Ich hatte gehofft, dass man Keybase einfach einen Link zu einem Profil auf einem beliebigen Discourse-Server, auf dem das Plugin läuft (oder auf jedem Discourse-Server, falls es in den Kern integriert wird), zur Verfügung stellen kann, und man dann auf jedem Discourse-Server einen Nachweis hätte.
Ja, der Plan ist, alle notwendigen Tools zu erstellen, und ich bin mir sicher, dass @kb_xgess dies für Communities aktivieren wird, wo es sinnvoll ist. Das bedeutet nicht, dass jede Geisterstadt oder jede Instanz mit Login-Pflicht diese Tools erhält.
Das ist der Weg, auf dem du KeyBase nachweist, dass du eine Website besitzt. Ich dachte, eine ähnliche Methode könnte funktionieren. Ich habe mich geirrt.
