Module: Subflag::Rails::Targeting

Defined in:

lib/subflag/rails/targeting.rb

Overview

Targeting module for evaluating rules that control who sees what flag values.

Rules are stored as JSON in the database and evaluated at runtime. Use targeting to roll out features to internal teams before wider release.

Rule Format

Rules are an array of objects, each with a value and conditions:

[
{
  "value" => "true",
  "conditions" => {
    "type" => "OR",
    "conditions" => [
      { "attribute" => "email", "operator" => "ENDS_WITH", "value" => "@company.com" },
      { "attribute" => "role", "operator" => "IN", "value" => ["admin", "qa"] }
    ]
  }
}
]

Supported Operators

• EQUALS, NOT_EQUALS - exact match
• IN, NOT_IN - list membership
• CONTAINS, NOT_CONTAINS - substring match
• STARTS_WITH, ENDS_WITH - prefix/suffix match
• GREATER_THAN, LESS_THAN, GREATER_THAN_OR_EQUAL, LESS_THAN_OR_EQUAL - numeric
• MATCHES - regex match

Evaluation

Rules are evaluated in order. First match wins. If no rules match, the flag's default value is returned.
