The Problem with as_jsonUsing Ruby on Rails default serialization:🔹 Issue: Models become bloated with formatting logic Business logic + presentation logic get mixed 🔹 Example problem:def as_json super.merge(custom_data: ...) end 👉 Key Insight Models should handle data, not how data is presented2. Introducing JBuilderUsing JBuilder:🔹 What it does: Moves JSON generation into view templates Keeps controllers and models clean 🔹 File structure:app/views/projects/show.json.jbuilder 👉 Key Insight JBuilder brings the MVC pattern back to balance3. JBuilder Template Basics🔹 Example:json.id @project.id json.project_title @project.title json.description @project.description 🔹 Features: Rename fields Select attributes Build structured JSON 👉 Key Insight You explicitly control every field in the response4. Handling Nested Associations🔹 Example:json.milestones @project.milestones do |milestone| json.id milestone.id json.name milestone.name end 👉 Key Insight JBuilder makes nested data easy and readable5. Adding Derived Data🔹 Example:json.single_day_project @project.start_date == @project.end_date 🔹 Use cases: Flags Calculations Business logic outputs 👉 Key Insight You can enrich API responses without touching the model6. Why JBuilder Is Better Than as_json🔹 With as_json: Logic scattered across models Hard to maintain 🔹 With JBuilder: Centralized JSON structure Cleaner, modular design 👉 Key Insight Separation of concerns improves scalability7. JBuilder Partials (Reusability)🔹 Problem: Repeating the same JSON structure 🔹 Solution: Use partials json.partial! \"milestones/milestone\", milestone: milestone 👉 Key Insight Write once → reuse everywhere8.
