Historically, I'm a django developer. I find myself suddenly in a position where I'll be doing a bunch of rails programming. I've browsed through the rails docs and done a bit of poking and prodding. Most assume that I've never seen a web framework or (worse) that I've never written code.
Ideally I'd like a resources that is targeted towards people who know django (pylons / sinatra / etc would be fine) and tells me the differences that I need to know to get on my feet with ruby.
Such things are incredibly hard to search for, because the web is littered with "django vs rails" articles.
Is there a good rails resource that assumes knowledge of other frameworks? What do I need to know, going from django to ruby?
I'm in the same position as you: I need to learn Rails for work, and I was hoping to find an article/tutorial that expresses Rails concepts in terms of how they differ from Django concepts.
After a lot of searching, I found this:
This compares the ways in which Rails and Django each implement various web development concepts.
It's very long and in-depth, but it's well structured so you can just dip into the bits you need help understanding.
One big downside, though: it was written in 2007. But it's still useful as long as you bare this in mind.
UPDATE:
I've also found this – a shorter, more up-to-date, cheatsheet-style comparison:
This one is good for quickly checking what terminology is used by each framework for a given concept.
I guess that the answer here is "No".
Maybe I'll write one.
