Scaffold not generating _form.rhtlml.erb fiel in app/view

I’m learning about Ruby on Rails. Please help me.
Althougth I do step-by-step with books(config data, generate model, add
data field in db/migrate/file.rb) but i can’t generate with scaffold or
When run command: ruby script\generate scaffold Employee
And check:
–> it shows successful with show,edit,destroy however it can’t show
data field although i inserted data in mysql. It shows:
Listing employees

            Show Edit Destroy
            Show Edit Destroy

            New employee

Or if i click on: New employee, it doesn’t have textbox to input data.
It shows:
New employee
