Do you mean "flash" messages from Flask?

I have not used Flask, but looking at that it does seem to be what I'm talking about.

I recommend you to check starlette-flash package.

It's very light but depends on SessionMiddleware to work.

Thanks. I got this working in my project. Here is what is looks like:

I roughly followed this: https://medium.com/@arunksoman5678/fastapi-flash-message-like-flask-f0970605031a

Which works with like your middleware suggestion above. And then it uses tabler's alert components.

Once I figure out how to get a dev setup in sqladmin I will submit it there.

Perfect, thanks

In practice how does one go about developing a feature in the core project? Do I start a demo project locally and link in the local sqladmin libs to see the changes there? Is there a particular demo to work off?

You can check this: https://github.com/aminalaee/sqladmin/blob/main/CONTRIBUTING.md
Chances are some steps might be old or wrong, but it should give you the idea how to contribute.

That doc explains how to checkout and build. But where do I actually run something to see my changes?

[aminalaee]

You can see the tests. You setup an example application within the project and when you run that example app it shows your changes.
