Limit total number of inserts / records per user

[johnclary]

Hi community—I'm developing a (FOSS ✨) app that will be free to use by anyone with an email address. I'm considering how I might limit the number of records a user can create based on their role. To use the articles/authors example, I may want to limit a user to creating at most 1k articles.

The most obvious approach seems to be a custom action that performs the validation, along with some app UI code that prevents the user from attempting to insert beyond the limit. Has anyone implemented something similar? How would you approach it?

Thanks :)
