this seems simple enough can't seem figure out. i have below models city -> hasmany locations locations -> hasmany restaurants restaurants -> belongsto locations this means restaurant linked city via locations now want find restaurants in particular city based location provided not restricted location rather city . the values provided city name , location name. can city_id , location_id // city locations $city = city::with('locations')->where('value', $c)->first(); $city_id = $city->id; // location id $location = location::where('value', $l)->first(); $location_id = $location->id; so $restaurants query should find restaurants location part of location of $city . how can achieve this? you can define hasmanythrough relationship - class city extends model { public function locations() { return $this->hasmany('app\location'); } public function restaur...

i have weird issue google indexing several of site's pages 'www.w.example.com' causing issues security certificate. while i'm looking solution, i'd redirect using .htaccess can't seem work. currently have: rewriterule ^(.*)www\.w\.(.*)$/$ https://www.$1/$2 [r=301,l] but doesn't seem work.. i have multiple domains site ideally needs redirect correct domain e.g. https://www.example1.com or https://www.example2.com you need use rewritecond matching host name: rewriteengine on rewritecond %{http_host} ^www\.w\.(.+) [nc] rewriterule ^ http://www.%1%{request_uri} [r=301,l,ne] however might still ssl cert warning because cert negotiation happens before mod_rewrite rules invoked.

i want download file ftp server have 2 ways 1)using ftpclient in java using commons-net-3.0.1.jar 2)linux binary ftpget of busybox now want know utilities should use in application? mean parameter should have consider while selection right method download file ftp that depends on requirements; there can't "generic" answer here. if using java library, have more control on whole "process" (you can call methods using known types, stuff that). if calling binary host operating system, means have dependency towards element harder control 3rd party java library. in both situations, have different sets of dependencies, application has check in end (and might easier ship java application version of apache commons library; versus making sure got specific ftp binary on customer systems).
