I would like to know some points about rails:
When I am in a completed post view and I resolve to leave it, how do I post an alert warning that I can lose these changes?
Is it possible to display a deleted post, or is it possible to insert that will be marked as deleted but still present in the database?
Is it possible to display an alert when a post with the same title already exists?
Is it possible that some fields appear in the edit view but do not appear in the creation view of a new post, since both are part of the same form?
