Open Issues Addressed by the Fork

#138 – Datasource-dependencies columns being passed as fields

✅ Resolved in v012: Introduced a DatasourceDependency class and extended each Worksheet with a .datasource_dependencies property.

• Dependencies now expose their own columns and column instances, separate from Datasource.fields.
• This distinction allows developers to correctly differentiate between true fields and dependency columns, avoiding the ambiguity in the original API.

#33 – Datasource Filters

✅ Resolved in v012: Added a Filter class that provides direct access to worksheet-level and datasource-level filters.

• Exposes filter class, target column(s), and nested groupfilter structures.
• Eliminates the need for manual XML parsing when analyzing filters.

Example:

workbook.datasources[3].filters
# Output: [<tableaudocumentapi.filter.Filter at 0x104765600>]

#164 – Expose all child objects of Workbook/Worksheet

✅ Resolved in v012: Added a Worksheet class that exposes structured child elements and objects, including:

• Datasource Dependencies
• Filters
• Rows
• Columns
• Column Instances
• Worksheet ID (UUID)

This provides full programmatic access to worksheet internals that were previously only accessible by traversing raw XML.

#246 – Missing attributes for meta-data records

✅ Resolved in v012: Extended support for column instances at the worksheet level.

• Each column instance now exposes contextual attributes (derivation, pivot type, etc.).
• Previously, this metadata was only available at the datasource level in the pre-fork API.

#129 – Retrieve all fields used in a workbook

✅ Resolved in v012: Added a Query object that supports high-level traversal of XML for cross-workbook analysis.

• Query.get_workbook_dependencies() generates a tabular usage report of all fields across dashboards and worksheets.
• Greatly simplifies complex dependency mapping that previously required custom XML logic.

workbook.query.get_workbook_dependencies()
# Outputs a tabular field usage report for every Dashboard and Worksheet
