For a model with this Schema...
{
name: { type: String }
}
...the following automatically casts the provided value to a string instead of enforcing the type:
document.name = 2;
document.validate(err => {
// Err is null, document.name === '2'
})
Is there a simple way to disable this behaviour?
Just in case anyone else stumbles upon this, it looks like mongoose will be supporting this according to this issue.
you can use lean() method with your find/findOne queries.
lean() will remove all the effect a mongoose schema has, i.e. it will return data as it is saved in MongoDB without any typecasting.
Note:- After using lean() you will not be able to call update or save on that returned data.
Also, this will increase your query performance.
example
Model.find().lean().exec((err, result) => {
console.log(result); //data without any typecasting
/*some operations on result*/
result.save(); // this will not work
});
