Validate only when value is changing
I'm using Sequelize 4.38.0
and have the custom validation for email on the User model.
The way the custom validation is constructed (see below), I need to skip the validation if the email property hasn't changed. Otherwise it halts the whole update operation (as it thinks the email address is already taken).
How can I run validation for a property only when the value is changing?
email: {
type: DataTypes.STRING,
allowNull: false,
validate: {
isEmail: {
msg: 'Wrong email format',
},
notEmpty: {
msg: 'Email has to be present',
},
isUnique: function(value, next) {
User.find({
where: {
email: value,
organizationId: this.organizationId,
},
})
.then(function(result) {
if (result === null) {
return next()
} else {
return next(' Email address already in use')
}
})
.catch(err => {
return next()
})
},
},
},
node.js validation sequelize.js

@mihai I've updated the description. The custom email validation is run on every update operation of an user instance. And I wonder if it's possible to skip that custom validation when the email value isn't changing?

Solved it with a conditional like this:
isUnique: function(value, next) {
if (this.changed('email')) {
User.find({
where: {
email: value,
organizationId: this.organizationId,
},
})
.then(function(result) {
if (result === null) {
return next()
} else {
return next(' Email address already in use')
}
})
.catch(err => {
return next()
})
} else {
next()
}
},
