Jul 1, 2025July 2025 (2025-07) monthly summary for the rubyforgood/stocks-in-the-future repo, focusing on delivering business value through end-to-end stock trading capabilities for students, improving data accuracy and UX, and strengthening code quality. Key features delivered: - Student stock trading flow (buy/sell): Implemented end-to-end functionality for students to buy/sell stocks, linking orders to users and stocks, and generating corresponding portfolio transactions. Updated UI to navigate to new order paths with transaction types. - Pending portfolio transactions: Created pending portfolio transactions when an order is created, enabling a reliable audit trail and smoother workflow. - Cash balances and visibility improvements: Corrected cash balance calculations to reflect available funds for purchases, included withdrawals in cash-on-hand, and restricted balance visibility to student users for a tailored UX. - Stocks UI enhancements: Added a stocks table partial, calculated current price from cents, and improved styling for the stocks index page to boost readability and engagement. - Documentation and seed/access updates: Added troubleshooting guidance for Ruby/ASDF installation, updated seed data with stock tickers, and refactored access control for StocksController to improve security and onboarding. - Code quality and linting improvements: Applied RuboCop fixes, updated Rails best-practices, extracted long methods for readability, refined parameter handling, and added clarifying comments about transaction types. Major bugs fixed: - Fixed test flakiness by requiring a non-null number of shares in trades, stabilizing buy/sell workflow tests. - Corrected cash balance logic so available balance accurately reflects funds usable for purchases. - Included withdrawals in cash_on_hand calculations to ensure correct liquidity reporting. Overall impact and accomplishments: - Accelerated time-to-value for student users by enabling a complete, auditable stock trading experience with consistent UI and data behavior. - Improved financial accuracy and UX by aligning cash handling with real-world expectations and restricting sensitive balances to students. - Increased maintainability and onboarding readiness through seed/data updates, documentation, and code quality improvements. Technologies and skills demonstrated: - Ruby on Rails, with emphasis on model associations (User, Stock, Order, PortfolioTransaction) and controller access controls. - UI/UX enhancements via partial rendering and front-end styling adjustments. - Data integrity and validation practices (input validation for shares, strong params considerations). - Code quality tooling and practices (RuboCop, Rails best-practices refactors, readability improvements).
