javascript - How to automatically add the current user to a model on save? -


i'm using built in user model of loopback application. want accomplish is, author of specific model entry (an article example) automatically saved model identified access token when it's saved.

i tried implement this, using relationship manager, built in user model not listed there.

optimally when querying articles, username available show in overview if current user authenticated.

** update **

after quite research found @ least way add current user loopback-context:

// see https://docs.strongloop.com/display/public/lb/using+current+context app.use(loopback.context()); app.use(loopback.token()); app.use(function setcurrentuser(req, res, next) {   console.log(req.accesstoken);   if (!req.accesstoken) {     return next();   }   app.models.user.findbyid(req.accesstoken.userid, function (err, user){     if (err) {       return next(err);     }     if (!user) {       return next(new error('no user access token found.'));     }     var loopbackcontext = loopback.getcurrentcontext();     if (loopbackcontext) {       loopbackcontext.set('currentuser', user);     }     next();   }); });

now i'm trying add user via mixin:

module.exports = function (model) {   model.observe('before save', function event(ctx, next) {     var user;     var loopbackcontext = loopback.getcurrentcontext();     if (loopbackcontext && loopbackcontext.active && loopbackcontext.active.currentuser) {       user = loopbackcontext.active.currentuser;       console.log(user);       if (ctx.instance) {         ctx.instance.userid = user.id;       } else {         ctx.data.userid = user.id;       }     }     next();   }); };

i opened issue on github.

i know question old might people

in loopback 2.x, need add model json

"injectoptionsfromremotecontext": true

then:

model.observe('before save', function(ctx, next) {   if(ctx.instance){      ctx.instance.userid = ctx.options.accesstoken.userid;   }else if (ctx.data){      ctx.data.userid = ctx.options.accesstoken.userid;   }   return next(); });

right in code, reading xlsx file, xssfworkbook, , writing database. but, when size of xlsx file increases, causes outofmemory error. can not increase server size, or divide xlsx file pieces. tried loading workbook using file (instead of inputstream), didn't either. i looking way read 10k rows @ time (instead of entire file @ once) , iteratively write workbook , database. is there way apache poi? poi contains called "eventmodel" designed purpose. it's mentioned in faq : the ss eventmodel package api reading excel files without loading whole spreadsheet memory. require more knowledge on part of user, reduces memory consumption more tenfold. based on awt event model in combination sax. if need read-only access, best way it. however, may want double check first if issue somewhere else. check out this item : i think poi using memory! can do? 1 comes quite lot, reason isn't might think. so, first thing check - what's source of prob...

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
