Sequelize.js。 如何加入 2 个表（一对一）

Question

I have 2 tables

--- registries id name 1 dev --- registries_meta registryId data 1 {dev: true}

And how to join it? My code:

 public static associate() { RegistriesModel.hasOne(RegistriesMetaModel, { foreignKey: 'registryId', sourceKey: 'id' }); RegistriesModel.belongsTo(RegistriesMetaModel, { foreignKey: 'id' }); return; }

I got an error:

 SQLITE_ERROR: no such column: RegistriesMetaModel.id

How to fix thia stupid associations? Expected query:

 SELECT * FROM registries LEFT JOIN registries_meta ON registries.id = registries_meta.registryId;

In your case Registries model is target model, and it has RegistriesMeta . So when defining association you need to define them like below:

 Registries.hasOne(RegistriesMeta, { foreignKey: "registryId" }); RegistriesMeta.belongsTo(Registries, { foreignKey: "registryId" });
