ruby on rails - How do I force a user to either register or login before their post is saved? -

-

i have post model, , can create post. before saved, user must logged in.

i using devise. how force them login/register before saved, , complete operation once that?

i thinking of doing before_save on post model. issue approach don't have access current_user object in model.

i unsure how save record, , continue operation once login.

another hacky way change f.submit regular button redirects them login page. issue approach doesn't save info , allow them hit "submit" upon successful login. have go through entire post/_form again - trying avoid.

sounds me problems avoided if forbid people access post-creating if aren't logged in. if there no cases user can create post without being logged in, make them log in first. 1 way make link leads post-creating (if there such thing) check if user logged in, , if aren't send them login form.
