javascript - Sequelize.JS many-to-many findAll not using join table -


i have following sequelize setup:

var sequelize = new sequelize('...', '...', '...', {     host: '...',     port: '3306',      logging:  true,      define: {         timestamps: true,         paranoid: true     } });  var period = sequelize.define('period', {     name: { type: sequelize.string, allownull: false },     periodstart: { type: sequelize.integer },     periodend: { type: sequelize.integer } });  var material = sequelize.define('material', {     name: { type: sequelize.string, allownull: false } });  var artefact = sequelize.define('artefact', {     accession: { type: sequelize.string, allownull: false },     simplename: { type: sequelize.string },     dimensions: { type: sequelize.string },     thumbnail: { type: sequelize.text },     storagedescriptor: { type: sequelize.text },     description: { type: sequelize.text } });   artefact.hasmany(period); period.hasmany(artefact);  artefact.hasmany(material); material.hasmany(artefact);  period.hasmany(period, { as: 'children', foreignkey: 'parentid', usejunctiontable: false }); period.belongsto(period, { as: 'parent', foreignkey: 'parentid' });  material.hasmany(material, { as: 'children', foreignkey: 'parentid', usejunctiontable: false }); material.belongsto(material, { as: 'parent', foreignkey: 'parentid' });  sequelize.sync().success(function ()  {     console.log('sync ok');      period.findall({ include: [ artefact ] }).success(function (periods)     {         console.log(json.stringify(periods, null, 4));     }); } ).error(function (err) {     console.log('sync fail');     throw err; });

the sync() call causes following create statements:

create table if not exists `periods` (`name` varchar(255) not null, `periodstart` integer, `periodend` integer, `id` integer not null auto_increment , `createdat` datetime not null, `updatedat` datetime not null, `deletedat` datetime, `parentid` integer, primary key (`id`)) engine=innodb; create table if not exists `materials` (`name` varchar(255) not null, `id` integer not null auto_increment , `createdat` datetime not null, `updatedat` datetime not null, `deletedat` datetime, `parentid` integer, primary key (`id`)) engine=innodb; create table if not exists `artefacts` (`accession` varchar(255) not null, `simplename` varchar(255), `dimensions` varchar(255), `thumbnail` text, `storagedescriptor` text, `description` text, `id` integer not null auto_increment , `createdat` datetime not null, `updatedat` datetime not null, `deletedat` datetime, `categoryid` integer, `findlocationid` integer, `storelocationid` integer, primary key (`id`)) engine=innodb; create table if not exists `artefactsperiods` (`periodid` integer , `artefactid` integer , `createdat` datetime not null, `updatedat` datetime not null, `deletedat` datetime, primary key (`periodid`, `artefactid`)) engine=innodb; create table if not exists `artefactsmaterials` (`materialid` integer , `artefactid` integer , `createdat` datetime not null, `updatedat` datetime not null, `deletedat` datetime, primary key (`materialid`, `artefactid`)) engine=innodb;

which expect. however, call period.findall(...) causes following sql , exception:

executing: select `periods`.*, `artefacts`.`accession` `artefacts.accession`, `artefacts`.`simplename` `artefacts.simplename`, `artefacts`.`dimensions` `artefacts.dimensions`, `artefacts`.`thumbnail` `artefacts.thumbnail`, `artefacts`.`storagedescriptor` `artefacts.storagedescriptor`, `artefacts`.`description` `artefacts.description`, `artefacts`.`id` `artefacts.id`, `artefacts`.`createdat` `artefacts.createdat`, `artefacts`.`updatedat` `artefacts.updatedat`, `artefacts`.`deletedat` `artefacts.deletedat`, `artefacts`.`categoryid` `artefacts.categoryid`, `artefacts`.`findlocationid` `artefacts.findlocationid`, `artefacts`.`storelocationid` `artefacts.storelocationid` `periods` left outer join `artefacts` `artefacts` on `periods`.`id` = `artefacts`.`periodid`;  error: er_bad_field_error: unknown column 'artefacts.periodid' in 'on clause'     @ query.sequence._packettoerror (/users/ndjm8/work/dev/sandbox/node_modules/mysql/lib/protocol/sequences/sequence.js:32:14)     @ query.errorpacket (/users/ndjm8/work/dev/sandbox/node_modules/mysql/lib/protocol/sequences/query.js:82:18)     @ protocol._parsepacket (/users/ndjm8/work/dev/sandbox/node_modules/mysql/lib/protocol/protocol.js:172:24)     @ parser.write (/users/ndjm8/work/dev/sandbox/node_modules/mysql/lib/protocol/parser.js:62:12)     @ protocol.write (/users/ndjm8/work/dev/sandbox/node_modules/mysql/lib/protocol/protocol.js:37:16)     @ socket.ondata (stream.js:51:26)     @ socket.eventemitter.emit (events.js:117:20)     @ socket.<anonymous> (_stream_readable.js:736:14)     @ socket.eventemitter.emit (events.js:92:17)     @ emitreadable_ (_stream_readable.js:408:10)     --------------------     @ query.sequence (/users/ndjm8/work/dev/sandbox/node_modules/mysql/lib/protocol/sequences/sequence.js:15:20)     @ new query (/users/ndjm8/work/dev/sandbox/node_modules/mysql/lib/protocol/sequences/query.js:12:12)     @ function.connection.createquery (/users/ndjm8/work/dev/sandbox/node_modules/mysql/lib/connection.js:48:10)     @ connection.query (/users/ndjm8/work/dev/sandbox/node_modules/mysql/lib/connection.js:100:26)     @ module.exports.query.run (/users/ndjm8/work/dev/sandbox/node_modules/sequelize/lib/dialects/mysql/query.js:26:17)     @ module.exports.execqueueitem (/users/ndjm8/work/dev/sandbox/node_modules/sequelize/lib/dialects/mysql/connector-manager.js:313:21)     @ /users/ndjm8/work/dev/sandbox/node_modules/sequelize/lib/dialects/mysql/connector-manager.js:269:25     @ adjustcallback (/users/ndjm8/work/dev/sandbox/node_modules/sequelize/node_modules/generic-pool/lib/generic-pool.js:187:7)     @ dispense (/users/ndjm8/work/dev/sandbox/node_modules/sequelize/node_modules/generic-pool/lib/generic-pool.js:211:9)     @ object.me.acquire (/users/ndjm8/work/dev/sandbox/node_modules/sequelize/node_modules/generic-pool/lib/generic-pool.js:260:5)

which appears isn't attempting use artefactsperiods table created result of sync(). i'm @ loss i'm doing wrong. self-referential relationships of period , material both function expected, many many don't work.

nevermind, after digging, known issue, discussed on:

  1. https://github.com/sequelize/sequelize/issues/515
  2. https://github.com/sequelize/sequelize/issues/745

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
