I want to create a post and gave the author_id = current_author.id.

#in post controller

def create
    @post = Post.new(post_params)
    @post.author_id = current_author.id if current_author
    ...

I've put this project on Github

As others pointed the possible solution. to make sure though,

run heroku run rake db:version and see if it matches your latest migration version in db/migrate/*

If it doesnt run heroku run rake db:migrate as oreoluwa and lolosco have said already.

I think you recently added the author reference to the posts table. To fix the error, I'd say you should try to do heroku run rake db:migrate. Let me know if that helps
