Unable to include models to retrieve values - mysql

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`
AS `Client.id`, `Client`.`Client_Name`
AS `Client.Client_Name`, `Client`.`Address`

AS `Client.Status`, `Client`.`Created_By`
AS `Client.Created_By`, `Client`.`createdAt`
AS `Client.createdAt`, `Client`.`updatedAt`
AS `Client.updatedAt` FROM `Lobs`
AS `Lob` LEFT OUTER JOIN `Clients`
AS `Client` ON `Lob`.`ClientId` = `Client`.`id` WHERE `Lob`.`id` = 2000;

mysqljs ER_PARSE_ERROR in valid request

I'm using mysqljs and I want to delete a row in a table with its id:
class_id is the id (string).
connection.query(
`DELETEĀ FROM classes WHERE id = ?`, [class_id], (err, result) => {
if (err) throw(err);
resolve();
}
);
Connection:
global.connection = mysql.createPool({
connectionLimit : 10,
host : config.mysql.hostname,
user : config.mysql.user,
password : config.mysql.password,
database : config.mysql.database,
charset: 'utf8'
});
But I got this error:

Can someone help me?

Unknown column "something" in `Field list`, What's wrong?

I'm writing a server at port 3000 and its job is to get the data from "Signup.ejs" input's values and then inserting them into the database.
All is fine but there's a problem, it says to me that TechnoBoy is an unknown column in Field list
I tried inserting "" or even `` around ${} but it didn't work well since a new error has appeared.
This is my Connection.js file that I use it to create a connection and then export it to connect it in my app's files:
let mysql = require("mysql");
let connection = mysql.createConnection({
host: "localhost",
user: "root",
password: "something",
database: "test"
});
module.exports = connection;
And this is my Server.js that I use it to create a server and connect to the database insert the data into it:
let connection = require("./Connection.js");
let bodyParser = require("body-parser");
let express = require("express");
let app = express();
let urlencodedParser = bodyParser.urlencoded({ extended: false });
app.listen(3000, function() {
console.log("The server at port 3000 is open!");
});
app.set("view engine", "ejs");
app.get("/Signup", (req, res) => {
res.render("Register");
});
connection.connect();
app.post("/Signup", urlencodedParser, function(req, res) {
console.log(req.body);
res.render("Register");
connection.query(
`insert into users (Username, User_Password) values (${
req.body.Username
}, ${req.body.Password})`
);
});
Error I receive when I insert some data into input fields:
Error: ER_BAD_FIELD_ERROR: Unknown column 'TechnoBoy' in 'field list'

The query I used(which is in connection.query btw):
insert into users (Username, User_Password) values (${
req.body.Username
}, ${req.body.Password})
Excuse me if this is a stupid question or something, I'm very new to backend and this one is my first try on it.
I'm an idiot. I configured Password field to be int so it can't enter strings but I passed it a string, that's why when I was passing it, it was saying wrong syntax and stuff.
Oh and also, I forgot to wrap the username with "" although I still don't know how it is a problem when the property is a string itself.
Problem got solved, it can be closed now.

All what i need is to return data from Model and include this data with others to get the count only
below my code and i used i some explanation in the code
models.Order.findAll({
where : {
userId : {
$and : {
$notIn: ['null']
}
},
serviceId : {
$and : {
$notIn: ['null']
}
}
},
limit : 10,
pageLength : 500,
order: '`id` DESC',
include: [
{
model : models.User,attributes : ['firstName','lastName','phoneNumber','rankId'],
include: [
{
model : models.Order
// return the count for orders
}
]
}
],
attributes: ['id','serviceId','orderStatus',
[sequelize.Sequelize.fn('COUNT', sequelize.Sequelize.col('User.Orders.id')), 'count']
],
group: ['`User.Orders`.`userId`']
so in the line
// return the count for orders
am trying to get the count for model
model : models.Order
thank you

Sails doesn't create mysql table

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.
Sending 500 ("Server Error") response:
Error (E_UNKNOWN) :: Encountered an unexpected error

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.

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.
