hi dan,
i apologize, i must have been unclear because it seems that you (& some of the commenters below) are dissecting some of my statements quite literally whereas i put a lot of disclaimery type of statements to try to indicate that this is a combo of personal opinion / hazy memory (if the commenter below ever sees this he can also now receive my apology about mentioning datamapper as an ORM gaining traction, that must be a memory from years ago when i still did RoR). :D
I am aware that RoR has been successfully adopted many places, but i guess part of what i failed to explain here (that thankfully foobarian touches upon a bit) is that i believe that part of the power of "a spec" in a programming context is to maintain a solid core of functionality, that then also paves the way for expanded functionality in the future based on extensions of a similar style of syntax.
I know Ruby & Rails teams are not one and the same, I just have many memories of experiences in that community where library evolution is not incremental, does not expand functionality, deprecates as a rival lib rises in popularity.
In Java you see 2 things -- slow spec evolution & incremental expansion of features. It takes time (I know the fast-moving lang communities hate this) but I find it makes for much more robust codebases that survive upgrade processes with wayyyyyy less re-factoring/re-writing, and in type even some libraries that had their own syntax start to embrace/support the spec (Hibernate implements JPA now...).
So.... I suppose, yes, it is a personal matter perhaps. Some companies have used Rails successfully. But in freelance it has kindof bitten me (the overhead of dealing with security vulnerabilities / gem upgrades alone is astronomically more than I've dealt with in upgrading Java projects). I understand that a competent team can handle this & enterprises can pour money into making it work, but as a programmer who often works alone & hates forced unplanned maintenance, it is a tough pill to swallow.
Also, maybe it is because I am dealing with a lot of enterprise/legacy code at times. Sure, maybe business logic shouldn't go in the database. But if someone supplies me a library of highly complex Oracle functions & tells me i need to wrap these into services ASAP, am I really going to begin an immediate re-write? I would prefer that my framework is just able to wrap these functions until a re-write can be scheduled (if the codebase isn't retired before then...). Also in the enterprise community I don't find as much of a desire to have ALL logic in the app layer... often devs feel that as long as a stored procedure / view / whatever returns a meaningful coherent entity that is useful in the business logic layer, they don't really care where/how the query was aggregated.
I also understand anything can be made to scale & work for an enterprise... but it takes enterprise-level support!! I am more a champion of the rogue programmer trying to build an enterprise with a few lines of code a day. ;)
Best,
john
