php - How to get good performances when using symfony 2 ACL system with a large number of object? -

-

in our project using symfony 2 acl system control access entities stored in database (postgresql).

everything works fine until want check permission on large quantity of object (a few hundreds). performance getting bad. on pages number of query database above 4000. number in fact in direct relation number of entities in our database. more grows more query on page need done.

is there way check user's authorization on many object while conserving descent performance (keeping number of query db low)?

there way load acl data related 1 or many different entities. system tries load them in small amount of query , keeps data around can reused without going database again.

private function loadblogpostsacls($blogpostrepository) {     $oids = array();     foreach ($blogpostrepository->findby(array(), array('date' => 'asc')) $blogpost) {         $oids[] = objectidentity::fromdomainobject($blogpost);     }      $this->aclprovider->findacls($oids); }

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
