通过猫鼬使用.where()与.update()查询?
如何在猫鼬中将.where()与.update()一起使用?查询条件是传递给.update()的第一个参数.我应该将查询条件的null传递给.update()并跟随一个.where('_id', id)吗?另外，我也可以将其应用于.findByIdAndUpdate()/.findOneAndUpdate()吗?
How can I use .where() with .update() in mongoose? The query conditions are the first argument passed .update(). Should I pass null for the query condition to .update() and follow it with a .where('_id', id)? Also, can I apply this to .findByIdAndUpdate()/.findOneAndUpdate() as well?
如果没有，是否有一个Query方法，我可以只用更新文档来.update()并通过链中的其他.where()方法指定条件?
If not, is there a Query method in which I can .update() with just the update document and specify the conditions via other .where() methods in the chain?
在Model类上调用where将返回Query对象，该对象具有您要询问的方法:update，findOneAndUpdate
Calling where on a Model class returns a Query object which has the sort of methods you're asking about: update, findOneAndUpdate.
因此您可以将它们链接在一起以执行以下操作:
So you can chain them together to do things like:
MyModel.where('_id', id).update({$set: {foo: 'bar'}}, function (err, count) {});
