## Resource

In this lesson, you’ll learn about: rapid resource building in Ruby on Rails using scaffolding and manual prototyping, and how to balance speed with control1. Understanding CRUD Operations🔹 Core actions: Create → add new data Read → retrieve data Update → modify data Delete → remove data 👉 Key Insight CRUD operations are the foundation of every web application2. The Power of ScaffoldingUsing Ruby on Rails generators:🔹 Command: rails generate scaffold Crypto name:string price:decimal 🔹 What it generates: Model Controller Views Routes Migrations 👉 Key Insight Scaffolding enables rapid prototyping by generating a full feature instantly3. When to Use Scaffolding🔹 Best for: Quick prototypes Learning Rails structure CRUD-heavy applications 🔹 Limitation: Generates extra (unused) code 👉 Key Insight Scaffolding prioritizes speed over precision4. Manual Prototyping (Cherry-Picking)🔹 Approach: Build only what you need 🔹 Steps: Create controller manually Define custom routes Build minimal views 👉 Key Insight Manual prototyping gives full control and cleaner architecture5. Custom Routes and Controllers🔹 Example: Define only specific endpoints instead of full CRUD 🔹 Benefit: More efficient and tailored application flow 👉 Key Insight Custom routing reduces complexity and improves maintainability6. Advanced Database Queries🔹 Using Active Record:Crypto.where(name: "Bitcoin") 🔹 Variations: Key-value queries Parameterized queries Symbol-based conditions 👉 Key Insight The where method enables flexible and powerful data filtering7. Managing Model Associations🔹 Relationships: has_many belongs_to 🔹 Example: A Company has many stock prices A Crypto has many price records 👉 Key Insight Associations connect related data into a cohesive system8. Using Rails Console🔹 Command: rails console 🔹 Use…
