i have encountered issue using subfolders codeigniter + hmvc. /system/application/modules/welcome/controllers/staff/welcome.php to access have access via http://www.app.com/welcome/staff/welcome unfortunately doesn't fit rest of url structure. how can remove first welcome url url http://www.app.com/staff/welcome i have tried adding route within module: /system/application/modules/welcome/config/routes.php like: $route['staff/welcome'] = "welcome/staff/welcome"; but unfortunately no luck. adding route real codeigniter route file works feel adding code external of modules modules work misses point of adopting modularisation. i hope able help. thanks, tim this line in routes.php correct: $route['staff/welcome'] = "welcome/staff/welcome"; you can try play order of routing rules, , put rule default controller ($route['default_controller'] = "home";) @ end. have project 4 modules , works fine

select u.username, count(t.tid) total tbl2 t join users u on t.userid = u.userid group t.userid the above query works fine , all, returns number of total task each user has atleast 1 task in tbl2 table. but want return users, if user doesn't have records associated him in second tbl2 table. want total show 0 users doesn't have records, how can accomplish this? the problem other answers given want select users have no associated records; using left join, users table on wrong (nullable) side of join. replace left join right join, syntax feels unintuitive me. the standard answer reverse order of tables while using left join: select u.username, count(t.tid) total users u left join tbl2 t on t.userid = u.userid group u.username note it's better practice (and, in dbmses, required) group on non-aggregated columns in select list, rather grouping on userid , selecting username.

i had 2 entities user , friends in app engine jdo in user had list of friends want when select table user retrieve entity friend list of friends associated user....how can perform in app engine ? relation between entities python described here (i guess pretty same java): http://code.google.com/appengine/articles/modeling.html it seems need many many relation. simplest way have list of db.key property in user model. can make sure whenever create new connection between friends, both lists of friends updated. alternatively define function searches db users have user's key in friends list, using gql query. imho seems less organised other method.

i'm trying test legacy code, using mockito. i want stub foodao used in production follows: foo = foodao.getbar(new bazoo()); i can write: when(foodao.getbar(new bazoo())).thenreturn(myfoo); but obvious problem getbar() never called same bazoo object stubbed method for. (curse new operator!) i love if stub method in way returns myfoo regardless of argument. failing that, i'll listen other workaround suggestions, i'd avoid changing production code until there reasonable test coverage. when( foodao.getbar( any(bazoo.class) ) ).thenreturn(myfoo); or (to avoid null s): when( foodao.getbar( (bazoo)notnull() ) ).thenreturn(myfoo); don't forget import matchers (many others available): import static org.mockito.matchers.*;
