Sample: Adding Tags to Content

This sample illustrates how to add a Migrated tag to both data sources and workbooks.

Both the Python and C# transformer classes inherit from a base class that handles the core functionality, then create versions for IPublishableWorkbook and IPublishableDataSource.

Transformer Class

To implement the tag addition in Python, you can utilize the following transformer class:

from typing import TypeVar
from tableau_migration import (
    ContentTransformerBase,
    IDataSource,
    ITag,
    IWorkbook)

T = TypeVar("T")


class MigratedTagTransformer(ContentTransformerBase[T]):
    def transform(self, itemToTransform: T) -> T:
        tag: str = "Migrated"
        
        itemToTransform.tags.append(ITag(tag))
        
        return itemToTransform
    
class MigratedTagTransformerForDataSources(MigratedTagTransformer[IDataSource]):
    pass

class MigratedTagTransformerForWorkbooks(MigratedTagTransformer[IWorkbook]):
    pass
