== Use-case 6 - Favorite Build

Initiating actor: User \\
Other actors: / \\

The registered user wants to add a build to a list of favorite builds. The system ensures the user is logged in and that the build exists. Then it stores the build as 'favorited' for that user.

== Scenario

Step 1. User goes to the COMPLETED BUILDS page. \\
Step 2. System gets the approved builds that the user can see. \\
{{{
SELECT 
  b.id,
  b.name,
  b.total_price,
  b.created_at
FROM build b
WHERE b.is_approved = TRUE;
}}}

Step 4. The user clicks on ADD TO FAVORITES button. \\

Step 5. The system checks if the build has already been added to the favorites list:
{{{
SELECT *
FROM favorite_builds
WHERE user_id = userId
  AND build_id = buildId
LIMIT 1;
}}}
* If the build hasn't already been favorited, the system inserts it:
{{{
INSERT INTO favorite_builds (user_id, build_id)
VALUES (userId, buildId);
}}}

* If the build was already favorited, the system removes it from the favorites list:
{{{
DELETE FROM favorite_builds
WHERE user_id = userId
  AND build_id = buildId;
}}}

Step 6. The user can see his favorited builds in the user dashboard, by clicking on the username in the top right corner.
