Declarative query builder for SQLAlchemy
Project description
filteralchemy is a declarative query builder for SQLAlchemy. filteralchemy uses marshmallow-sqlalchemy to auto-generate filter fields and webargs to parse field parameters from the request. Use it to filter data with minimal boilerplate.
For Django users: the design of filteralchemy is strongly inspired by django-filter.
