SetBuilder is a library for:
- Describing a set of constraints in a simple data structure that can easily be serialized
- Presenting that data structure in natural language
- Performing the set of constraints as a SQL query
The following Set describes a group of people:
[{ trait: :awesome, choices: ["are"] },
{ trait: :attended, choices: ["have"], school: "school" },
{ trait: :died, choices: ["have not"] },
{ trait: :name, modifiers: [{ operator: :is, values: ["Jerome"] }] }]
SetBuilder can render this Set in plain English:
[Those] who are awesome, who have attended school, who have not died, and whose name is Jerome.
It can also generate an ActiveRecord::Relation on an ActiveRecord model to fetch the people who fit in this set.
