javascript - Update undefined in sailsjs model afterCreate hook -


in sailsjs app, i'm trying add default avatar user after user created have aftercreate hook in models/user.js:

var user = {   // ...   attributes: {     avatar: { model: 'image' },     // ...   },   aftercreate: function(user, next){     var url =  sails.config.s3 + "/" + sails.config.default_avatar;     sails.log.info(user); // displays proper user     var data = { url: url, isavatar: true, user: user.id };      image.create(data)      .exec( function (err, image) {       sails.log.info(image); // displays proper image       user.update(image.user, { avatar: image.id})       .exec( sails.log.info );     });     next();   },    }

i keep getting error:

 /users/rcanty/workspace/project/server/api/models/user.js:55   return user.update(image.user, { avatar: image.id}).exec( sails.log.info               ^ typeerror: undefined not function     @ /users/rcanty/workspace/project/server/api/models/user.js:55:19    @ bound (/usr/local/lib/node_modules/sails/node_modules/lodash/dist/lodash.js:957:21) @ applyinoriginalctx (/usr/local/lib/node_modules/sails/node_modules/waterline/lib/waterline/utils/normalize.js:416:80) @ wrappedcallback (/usr/local/lib/node_modules/sails/node_modules/waterline/lib/waterline/utils/normalize.js:315:18) @ callback.success (/usr/local/lib/node_modules/sails/node_modules/waterline/node_modules/switchback/lib/normalize.js:33:31) @ _switch (/usr/local/lib/node_modules/sails/node_modules/waterline/node_modules/switchback/lib/factory.js:48:28) @ /usr/local/lib/node_modules/sails/node_modules/waterline/lib/waterline/query/dql/create.js:241:9 @ /usr/local/lib/node_modules/sails/node_modules/async/lib/async.js:157:25 @ bound.<anonymous> (/usr/local/lib/node_modules/sails/node_modules/waterline/lib/waterline/utils/schema.js:151:44) @ fn (/usr/local/lib/node_modules/sails/node_modules/waterline/lib/waterline/utils/callbacksrunner.js:60:10) @ iterate (/usr/local/lib/node_modules/sails/node_modules/async/lib/async.js:149:13) @ object.async.eachseries (/usr/local/lib/node_modules/sails/node_modules/async/lib/async.js:165:9) @ object.runner.aftercreate (/usr/local/lib/node_modules/sails/node_modules/waterline/lib/waterline/utils/callbacksrunner.js:63:9) @ after (/usr/local/lib/node_modules/sails/node_modules/waterline/lib/waterline/query/dql/create.js:236:17) @ /usr/local/lib/node_modules/sails/node_modules/waterline/lib/waterline/query/dql/create.js:223:67 @ bound (/usr/local/lib/node_modules/sails/node_modules/lodash/dist/lodash.js:957:21)

however seems i'm doing what's prescribed in waterline docs

i think type of thing should inside user controller, not inside model. trying modify model defining inside model defining.

move controller , call @ end of createuser function.

edit:

try moving function outside attributes object, , add var user = this;, can reference itself:

  var user = {     // ...     attributes: {       avatar: {model: 'image'},       // ...     },     aftercreate: function(user, next){       var url =  sails.config.s3 + "/" + sails.config.default_avatar;       sails.log.info(user); // displays proper user       var data = { url: url, isavatar: true, user: user.id };       var user = this; // internal reference        image.create(data)           .exec( function (err, image) {             sails.log.info(image); // displays proper image             user.update(image.user, { avatar: image.id})                 .exec( sails.log.info );           });       next();     }   }

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
