activerecord - Ruby on Rails Sql transactions -


i wondering if there better way manage transactions ruby on rails attaching class model ? 

student.transaction   course.transaction     course.enroll(student)     student.units += course.units   end end

i don't want transactions model specific, can begin/commit/rollback them genericly @ controller level no model dependency.

you can use activerecord::base.transaction.

afaik there no difference @ all. opening transaction 1 of models not limit usage of different objects not belonging model within transaction @ all.

see here: http://api.rubyonrails.org/classes/activerecord/transactions/classmethods.html

c++ - Correct method for redrawing a layered window -

i have window created ws_ex_layered window style. drawing onto memory bitmap using gdi+, , using updatelayeredwindow update graphical content of layered window. intend use window main window of application, require redraw frequently. seeing layered windows not receive wm_paint windows message [?] , need come appropriate method re-drawing window. optimisation not essential , it's nice have cake , eat too. therefore, in search of "correct" method use. here thoughts far: i guess it's idea render onto off-screen bitmap before bitblt ing or similar. 60 frames rendered per second should (more than?) enough (but how compare other applications' frame rates?). possible solutions: use settimer send wm_timer message on regular basis. useful because through specifying time-out value, can achieve desired frames per second, without requirement measure duration "frame" takes rendered. would cause input or other lags due frequency , speed of m...
