How would I add minimum/maximum constraints? #86

Open anuveyatsu opened 5 years ago

anuveyatsu commented 5 years ago

E.g., I have a table with time series and I wish to have constraints.minimum and constraints.maximum in the schema so that I have aggregated information about the table.

Is there a standard approach using existing processors or should I go for a custom processor?

You can use the set_type processor for setting constraints. Something like this:

set_type(fieldname, constraints=dict(required=True))
