php - View/Twig best practice: retrieve sub/child records in controller or view? -

-

i'm building application using twig , symfony, has general *vc.

when want retrieve child/sub/related records (for example subcategories of parent categories), should be:

  1. create nested array of data needed in controller , pass view/twig.
  2. retrieve sub records within view , loop through them there (initially passing in parent records).

this provided sub records can retrieved single method call or access single property. in view anyway, if requires more single method call, it's getting complex view.

i realize opinion based, i'm wondering if there best practices in general or twig or symfony.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
