# Update Asset

`PUT /api/projects/{project_id}/assets/{asset_id}`

Update an existing asset with a new generated image.
This is used for asset revisions - instead of creating a new asset,
the existing asset's image_url is updated.

Args:
    project_id: Project ID containing the asset
    asset_id: Asset ID to update
    prompt: New text description of the asset
    files: Optional list of reference images for generation
    preview: If True, generates image and returns URL without persisting to DB.
             User can then accept (call again with preview=False) or discard.
    commit_url: If provided, skips generation and commits this URL to DB directly.
                Used when accepting a previewed image.
    current_user: Authenticated user
    db: Database session
    
Returns:
    Updated asset data with new image URL
