Sequelize 使用对象类型创建模型

Question

Is this possible to create model with sequelize to look like:

var User = sequelize.define('User', {
    username: DataTypes.STRING,
    email: DataTypes.STRING,
    password: DataTypes.STRING,
    facebook: {
      id: DataTypes.STRING,
      token: DataTypes.STRING,
      email: DataTypes.STRING,
      name: DataTypes.STRING
    },
})

Idea is: When i will get user data from DB i would like to see User: { facebook: { id, token, ... } }

Answer 1

No.

Either

1. you make User.facebook a DataType.JSON field (which is supported by postgresql only)
2. you create an Entity 'facebook', which is 1:1 related to User

Option i) is fine, but you don't get any support from sequelize to check integrity and validity if you make it a json field.

Answer 2

Column dataType - TEXT save as JSON format after find table - return json patse text

 PodPodMaterial.afterFind(async (material) => { if(material.length) { for(let mat in material) { try { material[mat].ez_kolvo = JSON.parse(material[mat].ez_kolvo) } catch(e) {console.error(e)} } } else { try { material.ez_kolvo = JSON.stringify(material.ez_kolvo) }catch(e) {console.error(e)} } return material })
