Have you created a rails application ? What in your opinion is Post? Ruby expects to find a constant by that name. class names in Ruby are constants. constant is any word that starts with a capital letter.
If say you've written a class Post, then you must have done so in a file. You need to require that file when inside irb to load that class.
