Profiles and Media

Goal

This snapshot advances Emberquay Market by teaching you to edit profiles, shipping addresses, and product images.

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

Prerequisites

Use Elixir 1.15+, Mix, Node.js 20+, and Docker for Postgres stages.

Port 4002 must be free. Copy .env.example before database stages.

• Elixir and Mix
• Node.js and npm
• Docker from part 4 onward

Concepts

Uploads need image validation, size limits, and a public storage path.

LiveView keeps interactive UI on the server; Tailwind styles the storefront; Ecto owns persistence and authorization checks.

Walkthrough

Protect profile and address forms; store product images for sellers.

Read the example, then open the matching snapshot. The repository includes validation, CSRF, and the surrounding structure.

Accounts.save_avatar(user, upload)
Catalog.attach_image(product, upload)

Run and verify

Enter 08-Profiles-And-Media, mix deps.get, copy .env.example, migrate, seed, and start Phoenix on port 4002.

Open http://127.0.0.1:4002. From data lessons onward, Ada and Grace use password123.

docker compose up -d
git clone https://github.com/michaeldunga1/fcc-phoenix-ecommerce.git
cd fcc-phoenix-ecommerce/08-Profiles-And-Media
mix deps.get
npm --prefix assets install
cp .env.example .env
mix ecto.setup
mix phx.server

Troubleshooting

Broken images usually mean the public upload symlink or static mount was skipped.

For database failures, confirm Docker and the ember_NN name. Never commit .env, _build, deps, or node_modules.

• Read the first exception first
• Rebuild assets after Tailwind class changes
• Never commit secrets

Try this

Upload a valid product image, then reject a text file upload.

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
