I’m having this error: Typeerror: isPassword is not a Function. I did a lot of web searches, found similarities, but I still can’t solve it. So another way I solved, but as I’m starting the studies I wanted to know the pq does not pass, where I may be wrong in creating a classMethod and using it:
I created this js:
import bcrypt from "bcrypt";
module.exports = (sequelize, DataType) => {
const Users = sequelize.define("usuarios", {
id: {
type: DataType.INTEGER,
primaryKey: true,
autoIncrement: true
},
nome: {
type: DataType.STRING,
allowNull: false,
validate: {
notEmpty: true
}
},
password: {
type: DataType.STRING,
allowNull: false,
validate: {
notEmpty: true
},
field : 'senha'
},
email: {
type: DataType.STRING,
unique: true,
allowNull: false,
validate: {
notEmpty: true
}
},
datacadastro: {
type: DataType.DATE,
defaultValue: new Date()
}
},
{
hooks: {
beforeCreate: user => {
const salt = bcrypt.genSaltSync();
user.password = bcrypt.hashSync(user.password, salt);
}
},
classMethods: {
**//estou tendo erro em utilizar este isPassword**
isPassword: (encodedPassword, password) => {
return bcrypt.compareSync(password, encodedPassword);
}
}
});
return Users;
};
Here in this token.js that will be used to validate the email and password:
import jwt from "jwt-simple";
module.exports = app => {
const cfg = app.libs.config;
const Users = app.db.models.usuarios;
app.post("/token", (req, res) => {
if (req.body.email && req.body.password) {
const email = req.body.email;
const password = req.body.password;
Users.findOne({where: {email: email}})
.then(user => {
**//Na linha abaixo que acontece o erro citado**
if (Users.isPassword(user.password, password)) {
const payload = {id: user.id};
res.json({
token: jwt.encode(payload, cfg.jwtSecret)
});
} else {
res.sendStatus(401);
}
})
.catch(error => res.sendStatus(401));
} else {
res.sendStatus(401);
}
});
};
First of all, what is the first file? A file that defines the template for Users? Second, where do you import / require the first file?

I’m sorry if I didn’t explain it very well, but this is it.

Already tried to define class method so:
const Users = ...; Users.isPassword = ...; return Users– nbkhope
Sorry ignorance but as I am starting in Node js I did not try no: if (Users.methods.isPassword(user.password, password)) { .. would be so said for me to try gave error: Typeerror: Cannot read Property 'isPassword' of Undefined

Comments everything inside the callback of then. Set a function whatever of a log console, for example, as I said before. After defining Users with sequelize.define(), just say
Users.qualquerFuncao = () => console.log('qualquerFuncao!!');There inside the callback I mentioned at the beginning, calls the class function:Users.qualquerFuncao(). If this works, then your problem will be solved.– nbkhope
Thanks friend I found a way to solve, with your help and tips I found a link about sequelize that show how to migrate and what changed from one version to another, as I said I am at the beginning I took a tutorial to learn because I did not pay attention to the versions of frameworks.

It is always good to mention the version of the tool and always read the documentation referring to such version. This happens a lot when the main version changes from one to another.
