I am creating a method on my model that I can use to return the URL to the correct logo, photo or a fallback image. My code is:

def image
    if photo1.attached?
        { url: photo1.url, alt: "Photo of #{full_name}" }
    elsif photos.any?
        photo = photos.first
        url = photo.url(:large_square)
        { url: url, alt: "Photo of #{full_name}" }
    else
        { url: url_for(asset_path "placeholder.svg"), alt: "Placeholder for #{full_name}" }
    end
end

But it’s erroring with url_for and asset_path and i’m unsure how to resolve it?
