Dynamic Filters

Give the people using your admin a way to cut a crowded Index view down to the handful of records they're after, stacking conditions however they need, without you writing a scope for each one. Mark a field filterable: true and it becomes a filter, auto-mapped to the right control for its type: :text, :number, :date, :boolean, :select, or :tags. Each type carries its own conditions, so text gets contains and starts-with, dates get is-within and on-or-before, and numbers get the full set of comparisons.

Queries run through Ransack, so you whitelist columns with ransackable_attributes and filtering rides on the layer you already trust. Conditions on the same attribute combine with OR, different attributes with AND. When a plain field isn't enough, declare a dynamic_filter with your own label, query lambda, and query_attributes to reach across associations or into JSON columns. It's a gem you add, not a filtering UI you build, secure, and then maintain as your schema grows.
