Parent and Child object in SimpleRepository


How would it work in Subsonic's SimpleReporitory if I wanted to be able to have a 1 to many relationship between objects?

Would I have to create a bridge object and then build my parent object at runtime, or is this support built in?

What I am looking for is the folowing:

Adam's Example Shop...

Public Class Shop

    Private m_id As Integer
    Private m_Name As String
    Private m_Employees As List(Of Employee)

    Public Property Id() As Integer
        Get
            Return m_id
        End Get
        Set(ByVal value As Integer)
            m_id = value
        End Set
    End Property

    Public Property Name() As String
        Get
            Return m_Name
        End Get
        Set(ByVal value As String)
            m_Name = value
        End Set
    End Property

    Public Property Employees() As List(Of Employee)
        Get
            Return m_Employees
        End Get
        Set(ByVal value As List(Of Employee))
            m_Employees = value
        End Set
    End Property

End Class

Public Class Employee

    Private m_id As Integer
    Private m_Name As String

    Public Property Id() As Integer
        Get
            Return m_id
        End Get
        Set(ByVal value As Integer)
            m_id = value
        End Set
    End Property

    Public Property Name() As String
        Get
            Return m_Name
        End Get
        Set(ByVal value As String)
            m_Name = value
        End Set
    End Property

End Class

Main bits:

        Dim repo As New SimpleRepository("SubSonicObjectTest", SimpleRepositoryOptions.RunMigrations)

        Dim emplyee1 As New Employee
        emplyee1.Name = "Martin"
        Dim emplyee2 As New Employee
        emplyee2.Name = "Adam"

        Dim shop As New Shop
        shop.Name = "Sub Sonic Store"

        shop.Employees = New List(Of Employee)
        shop.Employees.Add(emplyee1)
        shop.Employees.Add(emplyee2)

        repo.Add(Of Shop)(shop)

I think this should create 3 tables:

Shops
Employees
ShopsToEmployees (or some other naming convention)

But I only get a Channels table!


Solution

  • I'm updating the SimpleRepo stuff currently to automatically create joined tables based on collections. Not easy to determine many/many vs 1/many - but I have some ideas :).
