Question

I would like to create a new model for a Ruby on Rails application. I know that this should do:

$ ruby script/generate model Book

But it gives me:

ruby: No such file or directory -- script/generate (LoadError)

Why is that? How can I fix that? I am in my application folder.

Answer 1

What version of rails are you running? As far as I know it should be script/rails – but I am running rails 3.1.3

Edit: as @Jeremy bellow stated, in rails 3 and up it is script/rails – or of course, more generally, just rails

Run

ruby script/rails -h

and you should see the available commands

Run

ruby script/rails generate -h

to see what is available to generate

Alternatively, you should also just be able to run:

rails generate -h

I have never found the ruby script/rails portion to be necessary, it defaults to that automatically
