In this lesson, you’ll learn about: enforcing low-level business rules in Ruby on Rails using validations, database constraints, and lifecycle hooks to ensure strong data integrity1. Understanding Business Rules🔹 Definition:Business rules = constraints that define how data should behave🔹 Focus:Low-level rules → apply directly to model attributes🔹 Examples:A name must existA ticker symbol must follow a specific format👉 Key InsightBusiness rules translate real-world requirements into enforceable logic2. Application-Level ValidationsUsing Ruby on Rails built-in validators:🔹 Common validations:presence → value must existuniqueness → no duplicates allowednumericality → must be a numberinclusion → must match allowed values🔹 Example:validates :name, presence: true, uniqueness: true validates :price, numericality: true 👉 Key InsightValidations act as the first line of defense against invalid data3. Testing Validations in Console🔹 Tool:rails console🔹 What to check:Attempt invalid savesInspect error messages🔹 Example:company = Company.new company.save company.errors.full_messages 👉 Key InsightError messages clearly explain why validation failed4. Custom Validation Logic🔹 When to use:When built-in validators are not enough🔹 Example:validate :ticker_length def ticker_length if ticker_symbol.length != 3 errors.add(:ticker_symbol, "must be exactly 3 characters") end end 👉 Key InsightCustom validations give full control over complex business logic5. Why Validations Alone Are Not Enough🔹 Problem:Validations can be bypassed (e.g., direct database access)👉 Key InsightApplication-level protection is not sufficient for critical data integrity6. Database-Level Constraints🔹 Solution:Enforce rules at the database level🔹 Migration example:change_column_null :companies, :name, false 🔹 Common constraints:null: false → prevents empty valuesUnique indexes → prevent duplicates👉 Key InsightDatabase constraints create a “bulletproof” safety layer7. Model Lifecycle Hooks🔹 Concept:Run logic automatically at specific stages🔹 Common hook:before_save🔹 Example:before_save :capitalize_ticker def capitalize_ticker self.ticker_symbol = ticker_symbol.upcase end 👉 Key InsightHooks automate data consistency without manual intervention8.
