Very important

  • To access the important data of the forums, you must be active in each forum and especially in the leaks and database leaks section, send data and after sending the data and activity, data and important content will be opened and visible for you.
  • You will only see chat messages from people who are at or below your level.
  • More than 500,000 database leaks and millions of account leaks are waiting for you, so access and view with more activity.
  • Many important data are inactive and inaccessible for you, so open them with activity. (This will be done automatically)

Get Sequelize.js ENUM Values from Already Defined Model

#1
How do we get the ENUM values of a model after defining it in Sequelize.js?

For example, we define our model as:

sequelize.define('model', {
states: {
type: Sequelize.ENUM,
values: ['active', 'pending', 'deleted']
}
})

How do we get the pre-defined `['active', 'pending' ,'deleted']` values from this model?

The ENUM values in a schema can be found in the `rawAttributes` property of the model.

var Model = sequelize.define('model', {
states: {
type: Sequelize.ENUM,
values: ['active', 'pending', 'deleted']
}
});

console.log(Model.rawAttributes.states.values);
// logs ['active', 'pending', 'deleted'] in console

Create JavaScript Enum Object like that


module.exports.BookingStatus = Object.freeze({
Done: 'Done',
Pending: 'Pending',
Rejected: 'Rejected'
});



Next, is to create sequalize Schema having enum

```
const Booking = sequalize.define(
'booking',
{
customerId : DataTypes.STRING,
bookingStatus : {
type : DataTypes.ENUM,
values : Object.values(this.BookingStatus),
defaultValue : this.BookingStatus.Pending
},
},
{
timestamps: true,
}
);
```
