Posts CRUD and Ownership

Goal

This snapshot advances Redrock Wire by teaching you to create, edit, and delete posts with owner authorization.

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

Authorization compares session user with post.author_id.

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

Walkthrough

Return 403 when another account mutates.

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

if user.id != post.author_id { return Err(StatusCode::FORBIDDEN); }

Run and verify

Enter 09-Posts-CRUD-And-Ownership, 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/09-Posts-CRUD-And-Ownership
cp .env.example .env
cargo run

Troubleshooting

UI hiding is not authorization.

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

Log in as Ada and confirm Grace's post returns 403 on delete.

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
