Answer 1

{ "$eq": [ false, "$isApproved" ] } will return true or false
db.collection.update(
{},
[ { "$set": { "isApproved": { "$eq": [ false, "$isApproved" ] } } } ]
);
Use findByIdAndUpdate

Answer 2

i change the code to this but i always have a false value
router.post('/:id/approve', auth, async(req, res) => {
console.log("action base de donne begin");
Post.findById(req.params.id, (err, post) => {
console.log(post.isApproved);
if (err) {
console.log(err);
} else if (post.isApproved == false) {
post.update(
{},
[ { "$set": { "isApproved": { "$eq": [ true, "$isApproved" ] } } } ]
);
} else {
post.update(
{},
[ { "$set": { "isApproved": { "$eq": [ false, "$isApproved" ] } } } ]
);
}
});
});
