Sequelize findOne latest entry

问题

I need to find the latest entry in a table. What is the best way to do this? The table has Sequelize's default createdAt field.

回答1:

Method findOne is wrapper for findAll method. Therefore you can simply use findAll with limit 1 and order by id descending.

Example:

YourModel.findAll({
  limit: 1,
  where: {
    //your where conditions, or without them if you need ANY entry
  },
  order: [ [ 'createdAt', 'DESC' ]]
}).then(function(entries){
  //only difference is that you get users list limited to 1
  //entries[0]
}); 

回答2:

model.findOne({
    where: {
        key: key,
    },
    order: [ [ 'createdAt', 'DESC' ]],
});
