提供对Djangoclusion_tag的阻止

Question

我有以下标签：

Public Class Form1

    Public Delegate Sub delegateSub()

    Public Sub func1()
        MsgBox("I AM FUNC1")
    End Sub

    Public Sub func2()
        MsgBox("I AM FUNC2")
    End Sub

    Public Sub func3()
        MsgBox("I AM FUNC3")
    End Sub

    Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim functions As delegateSub() = {New delegateSub(AddressOf func1), New delegateSub(AddressOf func2), New delegateSub(AddressOf func3)}
        InvokeDelegates(functions)
    End Sub


    Private Sub InvokeDelegates(ByVal functions() As delegateSub)
        For Each funcy As delegateSub In functions
            funcy.Invoke()
        Next
    End Sub

End Class

html文件：

@register.inclusion_tag('template.html')
def my_field(field: BoundField):
     return {"field": field, "spam":42}

但是现在我想为此标签提供一段HTML代码：

<span>{{ field }}</span> {{ spam }}

对于模板，我可以使用块，但是如何为includement_tag使用块呢？ 我可以创建自定义的编译函数并创建自定义的Node，但随后include_tag创建了{% my_field field %} <b>I want this code to be displayed instead of spam </b> {% end_my_field %} ，我无法控制它。
