Is there a way to get the attributes of // associations using a previously defined Sequelize Model?

Question

I need to get some data using a previously defined Sequelize Model.

What I need:

* attributes list * attribute name * attribute type (INTEGER, STRING,...) * was it generated by association method? * list of associations * association type (belongsTo, hasMany, ...) 

For some reason, it’s quite difficult to test the Sequelize models in the console:

 > db.sequelize.models.Payment Payment // <- it valid Sequelize Model {Object}, however its not inspectable > db.sequelize.models.Payment.attributes ... type: { type: { values: [Object] }, values: [ 'cash', 'account', 'transfer' ], Model: Payment, fieldName: 'type', _modelAttribute: true, field: 'type' }, sum: { type: { options: [Object], _length: undefined, _zerofill: undefined, _decimals: undefined, _precision: undefined, _scale: undefined, _unsigned: undefined }, Model: Payment, fieldName: 'sum', _modelAttribute: true, field: 'sum' }, ... 

As you can see, there is no actual information about the types of fields. The same thing happens with associations.

So, is there any reliable “official” way to extract this data from the Model class without digging and reversing the object?

Answer 1

Try Payment.rawAttributes , which is an object with the property name as a key and an object with property data. property.type.key is a string with a type.

Payment.associations - association object - the key is the name and each association will have the associationType property - you can also make an association instanceof sequelize.Association.BelongsTo , etc.
