Incorrect rounding in Custom Constraint example

[npatki]

If I follow the exact code in the Custom Constraint User Guide, the resulting constraint doesn't work as intended -- it never produces employees that are not constractors.

The issue is in the reverse_transform method. Instead of round(2) the code should be round().

i.e. change this line

rounded_data = transformed_data[is_included][column_name].round()

Further Context

In previous versions of the docs, we were multiplying by the increment first. Now, we are multiplying by the increment last. Therefore, it is necessary to round to the nearest whole number instead of 2 digits.
