Subject: Added bootstrap alert when body preview is empty
X-Git-Tag: live~326^2
X-Git-Url: https://git.openstreetmap.org./rails.git/commitdiff_plain/92f9d57a4072d11c6995a1291c587a48e6c50362

Added bootstrap alert when body preview is empty

Fixes #3748. Added check to SiteController#preview to detect if (message, diary entry, diary entry comment) body is empty and if positive, returns rendered bootstrap alert "Nothing to preview" to be displayed in richtext_field.
