Check for Slash Command Permission

Hey, I want to check if a user has the permission to use a slash command while taking into account all the different overrides (channel, roles, user etc.). (Im using this to match my prefix commands permissions with the slash commands)

• What's your exact discord.js npm list discord.js and node node -v version? • Post the full error stack trace, not just the top part! • Show your code! • Explain what exactly your issue is. • Not a discord.js issue? Check out method TextChannel#permissionsFor() Gets the overall set of permissions for a member or role in this channel, taking into account channel method GuildMember#permissionsIn() Returns channel.permissionsFor(guildMember). Returns permissions for a member in a guild channel, taking into account roles and permission overwrites.

Aren’t you able to set those up within the server settings?

Yes, im talking about the permission v2 that you can manage under the server settings > integrations

A friend made like a really complicated check for this and i was just wondering if you could do it with less code. I can send you his code snippet if you want to.

there we go you might have to load that into an editor because of formatting

Codeblocks: ```js const Discord = require("discord.js"); // further code ``` becomes
const Discord = require("discord.js");
// further code
const Discord = require("discord.js");
// further code
Inline Code: `console.log('inline!');` becomes console.log('inline!'); To share long code snippets use a service like gist, sourcebin, starbin, or similar instead of posting them as large code blocks.

ohh wait another problem the has method returns true if a permission exists. that permission could also allow the user to access the command

I dont think the channel permissions matter at all only the slash command overrides

You can take a look at the code, he did the checks in the order the types are applied Im not sure about the roles wdym overrides are missing?

Okay thank you :D Ill go through it and compare it to the old function
Lianecx

Im pretty sure the order is like that (all roles = everyone)

@lianecx did you use this in anything? I think I need to use something like this too
Lianecx

Discord has made some changes to permissions including a flowchart that should make it easy to implement something like this https://discord.com/channels/222078108977594368/992166350640386090/1042878335304347758
jolly jack
jolly jack2y ago
Yeah i saw the flowchart still a lot of work 😵‍💫
Lianecx
LianecxOP2y ago
I can send you my updated code once its done Its not released to every server yet so i havent changed it
jolly jack
jolly jack2y ago
ooh please do that'd be greatly appreciated
Lianecx
LianecxOP2y ago
👍 Feel free to ping me if I forget to post it
jolly jack
jolly jack2y ago
alr @lianecx hey, did you end up making this?
Lianecx
LianecxOP2y ago
I believe discord still has their new app permission system in beta. I also dont know if spoon feeding my code is welcome here 😅
monbrey
monbrey2y ago
Am I missing something here? That referenced post was from last year, definitely not a beta anymore
Lianecx
LianecxOP2y ago
It was opt-in for servers like a month ago idk if it still is I think its released they were planning to release it in late february I actually stopped support for my prefix commands so this wasnt needed anymore, with the flowchart that discord attached it should be pretty easy to implement this though as the discord.js objects and functions mostly resemble the discord api itself
jolly jack
jolly jack2y ago
Yeah I may have to have a stab at implementing the user/roles bit of it for my bot. Sorry for bothering you
Lianecx
LianecxOP2y ago
No worries, lmk if you need more help 😄
Lianecx
LianecxOP2y ago
If you still need this, a friend just implemented it for his bot, here it is:

jolly jack2y ago
I'll check this out at home, thanks for sharing
Lianecx

No problem!

obviously it's meant to do nothing while false trol makes me worry for when I open it up to look at I was hoping at the time it was in some sapphire library, it's not that I can't write it it's that it's annoying to write 🫠
