Validate.to_code()

Render this validation plan as canonical Pointblank Python code.

Usage

Source

Validate.to_code()

The to_code() method walks the validation plan and reconstructs the equivalent pb.Validate(...).col_vals_*()... method chain as a string. This is the inverse of writing the plan by hand: it takes an in-memory Validate object and produces source code that, when executed, recreates the same plan.

This is useful for sharing a plan, reviewing it in a diff, persisting it alongside results, and it is the foundation for the AI edit/iterate flow (see EditValidation), which sends the current plan to a model as editable code.

Returns

str

The validation plan as a block of Python code. The data source is rendered as the placeholder your_data, since the original data variable name is not known to the plan.

Notes On Fidelity

Most validation steps round-trip exactly. Steps that carry non-serializable Python objects, such as pre= preprocessing callables, actions=, callable active= conditions, or the expressions used by col_vals_expr(), conjointly(), and specially(), cannot be reproduced from memory. For those, a syntactically valid placeholder is emitted and a warning is raised so the code still parses and the loss is visible.

Examples

import pointblank as pb

validation = (
    pb.Validate(data=pb.load_dataset("small_table"))
    .col_vals_gt(columns="d", value=100)
    .col_vals_not_null(columns="a")
    .rows_distinct()
)

print(validation.to_code())
