Important

Introduces ViewQueryBuilder for handling view-based queries in DatasetLoader and adds related tests and schema validations.

• Behavior:
  • DatasetLoader now uses ViewQueryBuilder if schema.source.view is true, otherwise uses QueryBuilder.
  • ViewQueryBuilder formats queries with a WITH statement for views.
  • SemanticLayerSchema raises error if no relations are defined for views.
• Classes:
  • Adds ViewQueryBuilder extending QueryBuilder to handle view-specific query logic.
• Tests:
  • Adds test_view_query_builder.py to test ViewQueryBuilder functionality.
  • Adds tests in test_semantic_layer_schema.py for view relation validation.
  • Adds test_agent_chat.py for integration tests with various data scenarios.

3. pandasai/data_loader/view_query_builder.py:11

• Draft comment:
  Check if the query already contains a WITH clause before adding another one.
• Reason this comment was not posted:
  Decided after close inspection that this draft comment was likely wrong and/or not actionable:
  This is a valid concern - if format_query() is called with a query that already has a WITH clause, concatenating another WITH statement would create invalid SQL. However, I need to consider if this is actually possible in the codebase's usage. The class seems designed to build views specifically, and the WITH clause is core to its functionality. The parent QueryBuilder likely doesn't handle WITH clauses.
  I don't have visibility into how format_query() is used in the broader codebase. The query parameter could come from anywhere.
  While I don't have full context, the class name ViewQueryBuilder and its purpose strongly suggest it's specifically designed to wrap queries in WITH clauses to create views. Any code using this class would expect this behavior.
  The comment should be deleted. While technically correct, it goes against the class's core purpose of building view queries with WITH clauses.

4. pandasai/data_loader/semantic_layer_schema.py:171

• Draft comment:
  Check if self.relations is None before iterating over it to avoid TypeError.
• Reason this comment was not posted:
  Comment was on unchanged code.

5. pandasai/data_loader/semantic_layer_schema.py:172

• Draft comment:
  The error message can be improved for clarity and conciseness.

                raise ValueError("At least one relation must be defined for a view.")

• Reason this comment was not posted:
  Marked as duplicate.
