I am getting the above error When I accessing the http://127.0.0.1:3000/posts/show url its giving me the error

Couldn't find Post with id=show
Extracted source (around line #5)

@post = Post.find(params[:id])--here is line number 5
end
def create
@post = Post.new(post_params)

You need to supply an id. A record isn't found because you are supplying "show" as the id. http://ruby.railstutorial.org/chapters/sign-up#code-user_show_action

example: visit posts/1 instead of posts/show
