I created a rails application by “rails demo” command and generated a
controller “script/generate controller Say”. Then I created a file in
app/view/say/hello.html.erb. I added a method “hello” in
app/controllers/say_controller.rb. From a browser to access the link
"http://localhost:3000/say/hello, I got this error:
MissingSourceFile in SayController#index
no such file to load – sqlite3
What’s wrong with my application? Did I forget anything?
