I have been working on a project based on Michael Hartl's book Ruby on
Rails Tutorial in order to try to teach myself Ruby on Rails. However,
when it tries to render a form designed to allow a user to submit a
small message, I get an error saying, "undefined method `model_name' for
NilClass:Class". It says the error is at line 1, which is "<%= form_for
@micropost do |f| %>". I have the following defined in
app/controllers/microposts_controller.rb:
def new
@micropost = Micropost.new
end
I would have expected this code to create a blank Micropost object that
gets passed to form_for, but that doesn't seem to be what happened. I
attached a few files for reference.
