What am I doing wrong here when I wrote a very simple component so :
C:\ruby\letter4sure>ruby script\generate scaffold pso_printers
printing_setting_id:integer pso_id:integer
exists app/models/
exists app/controllers/
exists app/helpers/
create app/views/pso_printers
…
Then I did a rake db:migrate
And then I simply went to take a look at the url for the above :
http://localhost:port/pso_printers
NameError in Pso_printers#index
Showing pso_printers/index.html.erb where line #22 raised:
undefined local variable or method `new_pso_printers_path’ for

Extracted source (around line #22):
