Mike,
I feel your pain man....
This list is a community of very talented folks that embrace grails
for being the distilled and concentrated embodiment of many, many best
practices. It is unreasonable to expect the community to be receptive
to something the community is so strongly against....However you have
a point...Executing a SQL query and getting a DataTable like
representation that you can pass to a component is not idiomatic to
Grails, and nor is it idiomatic to Rails or Django for that reason.
Django does provide for more direct SQL access than the other
frameworks. Still, the best forum for what you want is still:
http://forums.asp.net/There are large architectural issues with building a framework like
grails and allowing the kind of functionality that you want. Possibly
you could get a session from hibernate and allow an HQL query, but
still I don't think of it as good form.
Java and C# are great languages. However, a great element of the
design of both of these languages is aimed at making them easily used
by a large body of developers. In a sense both of them are a sort of
dumbed down Objective-C or C++.....So basically, if you got C++ and a
garbage collection library, then you can't argue that Java is more
powerful than C++.....
So the point is, that don't complain that Grails is a more powerful
framework but doesn't allow you to do things which are considered
wrong by most of the community. There are good reasons why it is
hard to do bad things in a framework such as grails. Haskell would
never be the beauty of a language that it is if it allowed side
effects or a void type. However, Haskell is very more powerful of
language than Java(IMHO) and much more difficult to learn.
Adoption is an issue for Grails that I'm banging my head against. I
constantly am encountering projects that should be grails apps but are
not. I am not sure what the community and G2One can do to cross this
chasm but as I've recently been out talking to lots of different Java
web projects, I'm shocked that few of the technologists I've been
meeting consider Grails a serious web framework. It will take some
time and alot more evangelism than I'm currently seeing. But I hope
it happens. Being able to build projects in Groovy and have access to
the Java body of content is a great Joy and makes my life as a
developer much better.
If you want to execute queries, get a datatable back and then render a grid,
this is your forum:
