ruby on rails - How should I be updating data with AJAX? -


i making rails mvc style application.

when loading pages, controller gets data model , forwards view , view renders itself.

however, wondering appropriate way interact between javascript , database.

say user playing game , has bunch of clues on screen. clicking clue move clue box , needs update userclues model add clue.

the user needs able remove clues clue gets removed etc...

this needs happen via ajax.

i wondering appropriate approach is.

say got page /investigation loaded page using investigationcontroller.

should investigationcontroller 1 calling model add/remove clues, or should sort of data controller it.

for example:

/investigation/addclue

or controller

/user/clues/add

the reason asking have lot of data on pages created/added/modified , wondering if routes/controllers should separate data manipulation , pages, or if should have controller each page , manages user can on page (like add / remove clues , cluebox)

thanks

ideally want have separate controller each resource. though current view in context of investigations, controller, dealing clues should have own resource. otherwise things can complex. if clues investigation specific, can scope them under investigation url.

resources :investigations   resources :clues end

this give /investigations/1/clues/1, maybe not necessary, , avoid nesting unless required.

the controller can respond in correct format. in case rails ujs provides tools need. can render create.js.erb or destroy.js.erb templates handle user actions. templates have required javascript , dynamic code update screen state.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
