RealmSwift - Unable to get data after creating new collections

MongoDB Atlas App Services & Realm Atlas Device Sync

Hi there!

I’m using Realm Sync to develop an iOS app.
I recently added a new database with some collections and since I’m unable to retrieve any objects of any databases.
I tried to erase the new database and collections I added but still not working.
I also tried to restart Sync.

According to the log of my app, the connection is correctly established, the realm is well opened but it appears that there is no object on my collections. Here is a example where I’m opening a Realm to access a collection Customers to retrieve objects with the partition value “customers”:

Hi @Julien_Chouvet,
Could you please share the model of Customers object?

Hi @Pavel_Yakimenko

Here it is :

{
  "title": "Customers",
  "bsonType": "object",
  "required": [
    "_id",
    "_parentId"
  ],
  "properties": {
    "_id": {
      "bsonType": "objectId"
    },
    "_parentId": {
      "bsonType": "string"
    },
    "lastName": {
      "bsonType": "string"
    },
    "firstName": {
      "bsonType": "string"
    },
    "phoneNumber": {
      "bsonType": "string"
    },
    "email": {
      "bsonType": "string"
    },
    "address": {
      "bsonType": "string"
    },
    "notes": {
      "bsonType": "string"
    }
  }
}

Can we see the Swift Object model? Did you check the error log in the Realm Console? Any errors?

Are you using Developer mode?

The fact is that before I tried to add another db and other collections everything was working fine and I was able to get my customers objects as well as all the other objects of all my other collections. So I don’t think it come from my swift code.

class Customers: Object {

@objc dynamic var _id: ObjectId = ObjectId.generate()

@objc dynamic var _parentId: String = “”

@objc dynamic var address: String? = nil

@objc dynamic var email: String? = nil

@objc dynamic var firstName: String? = nil

@objc dynamic var invoices: String? = nil

@objc dynamic var lastName: String? = nil

@objc dynamic var notes: String? = nil

@objc dynamic var phoneNumber: String? = nil

@objc dynamic var quotes: String? = nil

override static func primaryKey() → String? {

return “_id”

}

}

I checked the Realm console and there is no error. And I’m not using the developer mode.

I tried to create a new Realm app (within the same cluster) and it is working, I’m able to get my customers objects.
Any ideas why it is not working in the initial Realm app?

Maybe … sounds a little like my problem … if you’re making schema changes check they are reflected correctly in the Realm App… i think mine got out of whack and yet i couldn’t always find anything in the logs.

8

Yes I saw your post! Is it working now for you?
What do you mean by :

How can I check that?

9

I’ve just tried again with my first Realm app (i.e. initial configuration) and now it’s working again…

In Data Access / Schema … glad you’re up and running again .
