the problem is there way eloquent model , all relationships using 1 query? example scenario: you have both post , comment eloquent models. add relationships in model class using hasmany('comment') , belongsto('post') respectively. now i've been doing retrieve both post , comments: $post = post::find($id); $post->comments; return $post; this returns beautiful json object. problem is, way, using 2 queries. that's not great. workaround two alternatives come mind: using join statements in order make query want. eloquent more elegant. leveraging cache class in order make fewer queries in future (this, anyway later on). any ideas? in eloquent can this $post = post::with('comments')->find($id); return $post; edit: not run query join in mysql single query in eloquent.

i have 4 domains, each different extension (.com / .de / .se / .no) i want domains load same main website folder on server, depending on extension language change on site. the domain names not same. eg. ostemad.dk cheeseflavour.com fromage.fr what question here? not need .htaccess style files @ all. files should avoided anyways wherever possible: considerably slow down server, error prone , hard debug. use real server configuration section instead: more clear , secure. you create 1 virtual hosts per domain , assign same document root each. for language switching can either rely on phps superglobal variables , switch depending on request host, or, more elegant, set environment variable inside virtual hosts definition means of apaches mod_setenvif.
