Sequelize 从外键获取 N:M 关联

Question

I have a schema where I have an Asset which has many threats and each threat has many countermeasures. What I want to do is given the id of an asset to get the list of the threats, and the list countermeasures for each threat, of that asset. How can I achieve that?

I don't think my code will provide any help, but here you go anyway:

Asset.belongsToMany(Threat, { through: 'asset-threat' });
Threat.belongsToMany(Asset, { through: 'asset-threat' });

Countermeasure.belongsToMany(Threat, { through: 'countermeasure-threat' });
Threat.belongsToMany(Countermeasure, { through: 'countermeasure-threat' });

All the association stuff are here. I let sequelize handle everything that has to do with keys foreiggn and not.

Edit

Something I tried to do that doesnt work but explains really well what I want to achieve is the following:

const asset = await Asset.findOne({ where: { id } });

return await asset.getThreats({
    include: Countermeasure
});

Answer 1

At least you should indicate include option values as an array:

return await asset.getThreats({
    include: [Countermeasure]
});
