Profiles and Media

Goal

This snapshot advances Redrock Wire by teaching you to show author profiles and accept constrained avatar uploads.

Every numbered folder is a complete app. Run this stage independently, then compare it with the previous folder.

Prerequisites

Use Rust 1.75+, Cargo, and a terminal. No Docker is required for SQLite stages.

Port 8082 must be free. Copy .env.example before starting database stages.

• Rust and Cargo
• A code editor and terminal
• Optional Docker only if you prefer another database later

Concepts

Upload endpoints must check type and size and store safe filenames.

Keep handlers thin: extractors accept input, sqlx queries enforce rules, and Askama escapes output by default.

Walkthrough

Protect profile editing and serve uploads.

Read the example, then open the matching snapshot. The repository includes the surrounding setup and error handling.

if content_type != "image/jpeg" && content_type != "image/png" { return Err(StatusCode::BAD_REQUEST); }

Run and verify

Enter 08-Profiles-And-Media, copy .env.example, run cargo run, and start on port 8082.

Open http://127.0.0.1:8082. Watch the terminal for validation and database errors.

git clone https://github.com/michaeldunga1/fcc-axum-blog.git
cd fcc-axum-blog/08-Profiles-And-Media
cp .env.example .env
cargo run

Troubleshooting

Confirm multipart enctype and field name.

For database failures, confirm Docker and the *.db name when applicable. Never commit .env or *.db.

• Read the first error first
• Restart after environment changes
• Never commit secrets

Try this

Upload a valid image, then reject a text file.

Test a happy path and one invalid or unauthorized request.

• Make one small change
• Test it in the browser
• Compare with the next snapshot only after it works
