I like that it doesn't use the CLI. I've always wondered who uses code generators. My sense is that experienced developers do not. And that novice developers are better off cutting and pasting. I personally loathe code generators which is one of the reasons I've never gotten in to Rails (I know I can do it without but seemingly all the instruction uses it).
Been doing rails for 3 years and web dev for 8. Scaffold generators are terrible but model generators save time on boilerplate code and give me most of what I want. Test libraries can hook into this process as well saving further time. Rails has plenty of drawbacks but I see some of the CLI capabilities as a strength IMHO.
It's the model generators that especially give me pause. I like to noodle around with my fields before putting them in place. I love designing my models in code.
