⚡️ Usage

In your Rails app or console:

require 'active_Buddy'

analyzer = ActiveBuddy::Analyzer.new(User)
puts analyzer.suggest_validations
puts analyzer.suggest_associations
puts analyzer.quick_audit

Output:

validates :email, presence: true
validates :email, uniqueness: true
validates :email, format: { with: /\A[^@\s]+@[^@\s]+\.[^@\s]+\z/ }
validates :name, presence: true
belongs_to :account

---

✅ Supported Patterns

ActiveBuddy automatically picks up and suggests validations based on:

Field Pattern	Suggested Validations
email	format, presence, uniqueness
phone, mobile	phone format
name, title	presence, length
password	length (>= 6)
age, count, qty	numericality (integer)
price, amount	numericality (>= 0)
bio, description	length (max 1000)
status, role, type	presence

Also detects and formats associations from ActiveRecord relationships.

🔍 Auditing model: User Fields detected: id, email, password, account_id, created_at, updated_at

✅ Suggested Validations: validates :email, presence: true validates :email, uniqueness: true

🔗 Suggested Associations: belongs_to :account

💡 Tips:

• Consider adding presence validations for key fields.
• Add associations if your model connects to others (like belongs_to, has_many).
