i've been trying learn spring , hibernate, , i've used lot of examples around net put nice application. however, realized spring supports transaction management. in spring app made whatever calls wanted to, directly hibernate. there reason/benefit why people use spring's transaction management/db stuff? the real advantages are: lightweight declarative syntax. compare: public void saveemployee(employee e) { session s = sf.getcurrentsession(); s.gettransaction().begin(); s.save(e); s.gettransaction().commit(); } and @transactional public void saveemployee(employee e) { sf.getcurrentsession().save(e); } flexible transaction propagation. imagine need execute saveemployee() method part of complex transaction. manual transaction management, need change method since transaction management hard-coded. spring, transaction propagation works smoothly: @transactional public void hireemployee(employee e) { dao.saveemployee(e); ...

the following sql query displays products sold sorted cost , number of orders have sorted in partitioned manner. namely, products cost of under $100 should go first , else > $100 should follow it. adding having ts.totalsold < 100 query accomplish first partition, filter out other products. operation should atomic, query can executed once. note: cost query has partitioned calculated max of 2 cost columns, makes things bit more complicated (the proposed solutions of case when won't work highestcost not column) select ps.productname, ts.totalsold, ((ps.cost1 + ps.cost2 + abs(ps.cost1-ps.cost2)) / 2) highestcost products ps cross apply (select (select count(orderid) orders os os.productid=ps.productid) totalsold) ts order highestcost asc, ts.totalsold edit : modified query include calculated cost query has partitioned. edited select * ( select ps.productname, ts.totalsold, ((ps.cost1 + ps.cost2 + abs(p...

i'm re-writing rails web app in c#. i'm stuck ruby's hash function: # generates 128 character hash def password.hash(password,salt) digest::sha512.hexdigest("#{password}:#{salt}") end the following c# function gives different result: private static string hash(string password, string salt) { return bitconverter.tostring(new sha512cryptoserviceprovider().computehash(encoding.utf8.getbytes(password + ":" + salt))).replace("-", "").tolower(); } what doing wrong? thank you never mind. results are same. if ever need convert ruby's hashing c#, digest::sha512.hexdigest(some_string) does same bitconverter.tostring(new sha512cryptoserviceprovider().computehash(encoding.utf8.getbytes(somestring))).replace("-", "").tolower(); c# lot more verbose, main thing works! :)

i thought overkill unpack entire gem application. there way override single view provides? this gem spree_easy_contact allows add contact form spree application. want tamper 1 of views alternative. if gem namespaced, can namespace view in local application. example, if gem namespaced best_gem_ever, app structure this: app - assets - controllers - helpers - mailers - models - views - - best_gem_ever - - - wonderful_controller - - - - index.html.erb at job, purposefully use technique allow clients overwrite front-end views while still pulling administrative views gem. works well. one caveat, if create asset files store in local assets folder, reason asset pipeline doesn't pick them up. have explicitly added config.assets.precompile list. hope helps!
