What kind of error is this?

I'm trying to update an entity with the following code:
db.Account.update({
'post_id': data.id
}, {
where: { id: account.id }
})
.spread(account => {
next();
});
but it doesn't work. Any idea?
The same issue I was facing and after a lot of debugging found out the silly mistake. The reason for me was in mysql added a column and forgot to add the same to sequelize model representing the same table so for your case also will suggest you to just double check for post_id is present in Account sequelize model.

I'm using the MySQL module for NodeJS, however I keep getting the following error after approximately 10 requests to the database. I'm using the following code to connect to the DB:
var con = mysql.createConnection({
host: "10.37.100.15",
user: process.env.MYSQLUSR,
password: process.env.MYSQLPASSWD,
database: process.env.MYSQLDB
});
Then I use con.query(sqlStatement, function (err, result, fields) {<function>}). I already tried changing the max_allowed_packet to 500M on the server but this didn't fix the issue. This is the full error:
events.js:377

default wait_timeout is 8 hrs.
I'd suspect the mysql-nodejs version isn't resetting the expected packet count on re-connection.
In a test environment you can reduce the wait_timeout.
It quite possibly is:

How do I fix this?
You most likely are inserting a row in a (an unspecified) table, but you forgot to specify the value for the column bio.
Therefore, you are trying to insert a null value on the column bio, and this columns is most likely defined as not null.
Solution? Either:
Put some value on the bio column before inserting.
Change the table definition and add a default value for the column bio.
Here is my (very simple) code :
var connection = mysql.createConnection(infosDB);
connection.connect()
connection.query(`SELECT * FROM action`, function(err, data){
console.log(data);
})
The action table is not empty... I think my database is ok.
This code works very well for me on localhost.
However, I bought A2 Hosting to launch node.js (v6.10.3 on localhost and server) project and I get that error when I try to launch this simple code.

Here are my model objects and get method.
model objects:models.js
var Client = sequelize.define("Client", {
name: DataTypes.STRING(100),
status : DataTypes.STRING(1)
});
var Lob = sequelize.define("Lob", {
name : DataTypes.STRING(100),
status : DataTypes.STRING(1)
});
Lob.belongsTo(Client, { constraints: true, foreignKeyConstraint:true });
Get method:
router.get('/getlobs', function(req, res) {
models.Lob.find({ where: { "id": 2000 }, include: [models.Client], attributes:["id", "name", "status"]}).then(function(lobs) {
return res.send(lobs);
});
});
With out include it works fine to get required attributes,while I am trying to get include Client model getting the error.Actually my intention to get client name insted of ClientId using foreign key relation.
Query:
Executing (default):
SELECT `Lob`.`id`, `Lob`.`name`, `Lob`.`status`, `Client`.`id`

I try to use my sails project on a server. I installed mysql.
When i call the request to create a user, sails doesn't automatically create the table "User".
I get this error:
sails-hook-sockets :: connected to Sails admin message bus.

Details: Error: ER_NO_SUCH_TABLE: Table 'mooz.user' doesn't exist
Here my model User.js
var Waterline = require('waterline');
// Define your collection (aka model)
var User = Waterline.Collection.extend({
attributes: {
connection:'mysql',
tableName:'user',
id: {
type: 'string',
required: true,
primaryKey: true,
unique: true
},
username: {
type: 'string',
required: true
}
}
});
My model.js:
module.exports.models = {
connection: 'mysql',
migrate: 'safe'
};
My connection.js:
module.exports.connections = {
mysql: {
adapter : 'sails-mysql',
host : 'localhost',
user : 'user',
port : 3306,
password : 'test',
database : 'mooz'
}
};
And my userController
module.exports = {
createUser: function(req, res){
var params = req.params.all();
User.create({username: params.username, id: params.id}).exec(function createUser(err,created){
return res.json({
notice: 'Created user ' + params.username
});
});
}
};
I don't understand why sails can't create automatically the table, did i forget something? Is there any command to do?
Thanks.
EDIT: Resolved with dev environnement
You can try to set migrate: 'alter' in model.js, and sails lift again.
