在 Postgres 中使用 Sequelize 更新特定的 JSON 字段

Question

I have a "user" table with one of the fields "info" being a JSON structure:

user table has these fields: id, name, info, created

info filed has this structure:

info: { email, password, device: { type, token } }

How can I use Sequelize to update the token field for a specific user in Postgres?

Answer 1

I know that this is a question about sequelize.js , but I don't know much about it, so let me give a general answer about postgresql (feel free to ignore it). First, postgresql does not support modifying json values. json columns should mostly be used to store JSON data in the database and not to manipulate JSON data. If you really want to manipulate JSON data in the database then you have to use a jsonb column. jsonb can be modified with the help the jsonb_set function and the || operator. In your case, if you can run raw SQL queries, you could do something like this:

UPDATE "user"
SET info = jsonb_set(info,'{device,token}','123')
WHERE id = 31;

Answer 2

user.findOne({where: {id: 31}}).then((u) => {
u.device.update(info: {type, token})

});

This is a user table. with id of 31 to update the value of type and token
