This is my first email to this discussion group.
I’d have one question. Is there an Arel guide planned?
I found Arel quite undocumented, I had to search a bit to find some stackoverflow discussions (but just once I luckily discovered that something like this exists), blog entries or presentations, when I think this topic is so important that it should have it’s own guide so that anyone new to Rails could get easily started with it (or at least he/she could notice that something like this is available).
Arel is mentioned on the ActiveRecord Query Interface page, but it’s only one use-case without any further explanation.
I found these links very useful:
If no guide is planned, then I’d suggest that at least a short introduction could be added to the RoR guides, listing some useful links where more information could be found.
I find this topic very important, because I have seen other libraries (in other frameworks) enabling describing complex business-related queries in a very elegant and efficient way, and till now I thought this is not existent in Rails.
Thank you all for your hard work,
