cakephp difference between Router::scope and Router::prefix -

-

i know router's prefix method adds prefix routes still confused scope method routes.is alias prefix or has own use.

router::prefix('api', function ($routes) {         $routes->scope('/v1', function ($routes) {                         $routes->connect('/', ['action'=>'index']);                $routes->connect('/:id', ['action'=>'view', ':id']);          });  });

both allow sharing of common path segments. difference prefix controller within sub-namespace.

from documentation:

prefixes mapped sub-namespaces in application’s controller namespace ... using our users example, accessing url /admin/users/edit/5 call edit() method of our src/controller/admin/userscontroller.php passing 5 first parameter. view file used src/template/admin/users/edit.ctp

in above case, scope controller @ src/controller/userscontroller.php.

mysql - FireDac error 314 - but DLLs are in program directory -

-
i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.

-
so per documentation https://developer.github.com/v3/repos/releases/#list-releases-for-a-repository get /repos/:owner/:repo/releases should list relases , https://api.github.com/repos/jquery/jquery/releases should list releases in jquery project , not , why ? because repository doesn't have releases. has tags github presenting in releases page. for more clear example, see: https://github.com/hashicorp/terraform/releases which has both releases , tags showing on page, api shows releases: https://api.github.com/repos/hashicorp/terraform/releases
