media-tools / sqlite-net-extensions Goto Github PK

Im trying to establish a one to one relationship with same entity type, but I can't understand why the data gets inserted incorrectly and even when I insert the data manually, when I try to gets them, instead of getting the object that have his PrimaryKey = to the ForeignKey, it go gets the object that has his ForeignKey = to the ForeignKey.

[Table("Localisations")]
public class Localisation
{
    [PrimaryKey]
    public  int Id { get; set; }

    public  string Label{ get; set; }


    [ForeignKey(typeof(Localisation))]
    public int ParentId{ get; set; }

    [OneToOne]
    public Localisation? Parent{ get; set; }
    
}

Please consider using System.Text.Json for serialization instead of Newtonsoft.Json as System.Text.Json already exists in the .Net and don't need additional pakage.
Although I see many people complaining about getting errors related to Newtonsoft.Json being used.

Hi!

First of all, I have to say, you've coded a nice piece of software. Makes life with Sqlite-databases much easier!

It would be even better if you could consider filling Lists/Arrays/ObservableCollections instead of overwriting them with a property setter. This would make object models even more clean.

Example: You have the following object property:
[OneToMany(CascadeOperations = CascadeOperation.CascadeRead)]
public List<Foo> Bar { get; set; }

more clean would be (as it would allow other objects to only add or remove items from the List:

[OneToMany(CascadeOperations = CascadeOperation.CascadeRead)]
public List<Foo> Bar { get; } = new List<Foo>();

In the SQLite-Net-Extensions, the method for setting this List has to be extended with something like

List.Clear();
List.AddRange(IEnumerable<T> readObjects);

With best regards,

I stucked with some primitive object as string => List

    public class EventData
    {
        [PrimaryKey, AutoIncrement]
        public int Id { get; set; }
        [JsonProperty("eventType")]
        public long EventType { get; set; }

        [JsonProperty("eventValue")]
        public string EventValue { get; set; }

        [JsonProperty("date")]
        public DateTimeOffset Date { get; set; }

        [JsonProperty("device")]
        public string Device { get; set; }

        [JsonProperty("name")]
        public string Name { get; set; }

        [JsonProperty("classname")]
        public string ClassName { get; set; }

        [JsonProperty("parameters")]
        [OneToMany(CascadeOperations = CascadeOperation.All)]
        public List<string> Parameters { get; set; }
        public string EventTypeString { get; set; }
        public string DateFormated { get; set; }
                
        public string EventGlyph { get; set; }

        public string EventColor { get; set; }

        public string EventFont { get; set; }
    }

It wont recognize List, I m getting message to add a fk on that? How to do that when I dont have a complex model?

Hello,
I've been testing my Xamarin.Forms on iOS and ran into an error with the WithChildren methods.
My code:

try
{
    return DB.GetAllWithChildren<T>().ToArray();
}
catch (Exception ex)
{
    return null;
}

Where DB is SQLiteConnection....

Usually this works well, but sometimes when I open the app it gets stuck on this specific line, or a similar line containing GetWithChildren.

I'm not sure what's going on, but it feels like some kind of deadlock issue in the library that seldom occurs but can happen.

Your help would be appreciated.
