Unable to use mongo _id for await User.find(_id).

Able to find user with _id (objectID2) and user generated _id (abc2) but not working with auto-generated _id (“607cf59ec294c8c3f1261e4f”)

await User.find(_id as any)  // works with _id as objectId
User { 
  _id: ObjectId2 {
    [Symbol(id)]: Buffer2(12) [       
       96, 124, 245, 158, 194,        
      148, 200, 195, 241,  38,        
       30,  79
    ]
  },
  name: "user1"
}

await User.find("607cf59ec294c8c3f1261e4f")  // undefined

await User.find("abc1") // works

Auto-generated _id is 607cf59ec294c8c3f1261e4f

Auto-generated _id returns undefined

User generated _id works

Hey Mayur,

Thank you for sharing all this. I’m sure this can easily be fixed 😃

I’ve looked at the mongo connector and basically whenever you do .find(...) this is what it does:

await User.find(id);
// =>
await User.where({ _id: id }).get();

If we make an update, delete something, the id problem would be similar:

await User.where({ _id: id }).update({ name: "Mayur" });

From my perspective, it then seems that the where clause is the issue every time.

What we could do is to check whenever the connector has to deal with wheres, it could:

* Check for the field name

* If it equals to `_id`, then wrap it with an object id

* Otherwise do nothing (we keep the field name)

I could give it a try but if you’re adventurous:

* Look for `.wheres` and `.whereIn` into the [mongo connector](https://github.com/eveningkid/denodb/blob/master/lib/connectors/mongodb-connector.ts)

* [This is how `.wheres` are added to a query](https://github.com/eveningkid/denodb/blob/8dfb7ad30862b9d5a9bed967cda6c48a0101946a/lib/query-builder.ts#L177)

* [This is how `.whereIn` are added to a query](https://github.com/eveningkid/denodb/blob/8dfb7ad30862b9d5a9bed967cda6c48a0101946a/lib/query-builder.ts#L142)

The goal is to only update the mongo connector, not Model that should remain generic.

Let me know if you want to give it a try 😃

Tried this in #240

Sure. I’ll try it.
