Feature Request: Enhanced Soft Failure support #122
Description
Just started experimenting with dataframely and liking a lot of what I see.
It would be great if Soft Failure support was extended in a way that makes it easy to generate failure reports for users who supply the input data.
Some ideas that sound useful to me:
- Provide a way to mark a set of columns as debug ID columns for Failure reports
- Extend FailureInfo counts and cooccurrence_counts methods with a "group_by_ids=True" or "group_by='id'" or similar parameter - if set, errors are grouped by the id columns suggested above
- it would be great if friendly names (that have a meaning to non technical users) could assigned to dy.rule

raayu83 could you elaborate what's currently missing to assign "friendly names" to rules? The rule assumes the name of the function which allows you to provide arbitrarily expressive names.

Hi Oliver Borchert (@borchero) ,
What I mean is an alternative representation of the Name that looks cleaner and allows you to use any character you want.
I'd like to add that I see this as a nice bonus feature, nothing really important to get things done.

Fair enough. I am personally not a fan of adding this as it will allow providing arbitrary names to
@dy.rules but you're still restricted to auto-generated names for column-level checks (e.g. nullability, min, max, ...). Maybe we can reconsider this at some point as dataframely's usage area expands but I will close this for now.borchero commentedon Feb 18, 2026
Ah prematurely closed this, I only meant to close the "friendly names" part. Will keep open.
