Sequelize - How to list/view all columns of existing model

Question

I know a simple answer could be query table with all attributes returned.

However, since the models are defined in code, I want to know is it possible to get the result without querying database? Or, if query is necessary, which query is the optimised one?

Btw, I am using Sequelize V5 and Mysql 5.7 .

Answer 1

You can iterate over rawAtributes of Model

for( let key in Model.rawAttributes ){
    console.log('Field: ', key); // this is name of the field
    console.log('TypeField: ', Model.rawAttributes[key].type.key); // Sequelize type of field
}

adicitionaly you have a lot information in this Model.rawAttributes, check it with Object.keys(Model.rawAttributes) and after see those values

Answer 2

It seems each model has an attribute "rawAttributes" which include all columns name. This may not be the official way, but it can solve my problem.

Answer 3

You can also use this as an answer:

for( let key of Object.keys(models.Modelname.attributes))   {
      columns.push({
          name:key,
          type:models.Modelname.attributes[key].type.key
      });
}
