One thing that took me a while to wrap my head around is concerns. Part of that is just that I hadn’t really used them before and they’re more of a Ruby (and Rails) thing that with other languages. At the same time, they’re SUPER powerful and helpful. It feels like people could see the power of Rail…

We did it folks!!! https://github.com/rails/rails/pull/39766 is now merged. I got so much great feedback and honestly learned a lot during the process. Thank you all so much for your help, I couldn’t have done it without you! :sparkling_heart:

do you have a link to those videos?

Looks like the preferred home is The Getting Real Basecamp YouTube channel .

On the other side, I’ve been on Rails for about the same duration, and I couldn’t imagine my life without them. I will break out into concerning :X do; end at the snap of fingers. There really seems to be an information gap here as there is one with Git :eyes:

Hah, I thought this thread was about ActiveSupport::Concern TIL about Module::Concerning

I was thinking of ActiveSupport::Concern but Module::Concerning is also part of this too.

IMO, the problem with concerns, is that they are really nothing special, they are just plain Ruby modules. But the fact that a new word was introduced creates an expectation that you’re missing something. Which is something I totally understand. A concern is a module that you extract to split the i…

[image] fxn: And you see the problem, concerns are so simple that they do not deserve a full guide. Concerns are mixins, if you are a Ruby programmer, you already know what a mixin is and their use case to modularize APIs. I think there’s a lot of Rails users that don’t know this. I think the…

[image] wwahammy: I think there’s a lot of Rails users that don’t know this. I think there’s a decent number of Ruby devs who know vaguely about mixins but they don’t use it because they don’t understand it. Maybe, but you have to draw the line somewhere, in my view it is out of the scope of …

[image] fxn: Maybe, but you have to draw the line somewhere, in my view it is out of the scope of Rails documentation to teach you Ruby. As a Ruby programmer, you need to learn Ruby. I mean, if we’re here to talk about getting folks up to speed on using Rails properly I don’t think this is a …
