Question

I m trying to select/delete entries from my mongodb via node.js and mongodb-wrapper. I get the id of the entry as a string via a http request. Then I want to delete the entry with the specific id.

app.delete( /posts/:id , function(req, res) {
res.header("Access-Control-Allow-Origin", "*");
db.posts.remove({"_id": req.params.id}, function(err) {
    if (err) return res.send(err.message, 500); // server error
    res.send(200);
  })
res.send("ok");
});

But this is not working. I already tried several ways but nothing deletes the entry. I have red something that I must convert the string into a ObjectId but until now I didn t found anything how to do this via mongodb-wrapper.

采用:{>_id”: req.params.id} 您正在问,有人说谎,而不是客气。同上。页: 1 反对:

var ObjectID = require( mongodb ).ObjectID;
var oid = new ObjectID(req.params.id);

如果数据重q.params,这将造成错误。补贴不能转化为有效的目标。
