Receiving Error: Cannot find module './adapters/role-acl when attempting to add authorize to one of my models

I hope this message finds you well. In trying to implement "const authorize = require('objection-authorize')(acl, library[, opts])" from the Usage section of your repository, I am stalled due to a missing dependency in the objection-authorize directory. It looks like node is trying to find it and it appears to be missing.


I'm very much liking the project and hope this can be resolved. In my project, I added the file directly from the role-acl repository but only to see if the issue would be fixed in any way. Thank you for your time.

It looks like you're trying to use role-acl. As outlined in here: https://github.com/JaneJeon/objection-authorize#installation, for now I only support casl (because that's what I use), which is why it's saying it can't load the role-acl adapter - because, well, it doesn't exist!

I did used to support role-acl (I think back in v3? don't use that version please, there's been numerous improvements that have been made since); however, with the project being abandoned I dropped support for it as well, so if you want to continue using role-acl, there's nothing stopping you from implementing the adapter (everything else is already done) specifically for role-acl.

In particular, you should write an adapter that override these methods: https://github.com/JaneJeon/objection-authorize/blob/master/src/adapters/base.js#L97, and you can see an example of such implementation here: https://github.com/JaneJeon/objection-authorize/blob/master/src/adapters/casl.js.

The "base" adapter already has all of the context necessary for the ACL library (in your case, role-acl) to make the decision to reject things or not. All that is left is for you to basically wrap it in a way that role-acl understands.

Thank you, @JaneJeon . I wasn't trying to use role-acl but I will keep your feedback in mind from this point. Thank you also for getting back to me quick.

[JaneJeon]

Oh my god, I just realized what is going on now. You initialized the plugin WITHOUT specifying the library (in this case, it should be casl), and it defaulted to role-acl - a relic from the past.

I'll fix this and release a new version ASAP

[JaneJeon]

Okay, I addressed it in https://github.com/JaneJeon/objection-authorize/releases/tag/v5.0.2. Try pulling the latest version :)

Awesome, @JaneJeon ! Thank you for digging into it and finding the root cause of the issue there.
