Hello,  
I would like to generate a model through my rails 3 application.  
Eg I can type:  
rails g model Abc  
at the command line.

I want to do the same through my application.

I have done it before with an earlier version of rails eg :

Rails::Generator::Scripts::Generate.new.run([‘model’,@name])

but I am not sure of the command in Rails 3, and the ‘require’  
statements to ensure I won’t get any ‘no such file errors’.

There is plenty of documentation on how to create a generator but not  
the more basic step of how to run the existing ones,

thanks in advance,  
Hal

I don’t know exactly how generators have changed but I’m curious - why  
would you want your app to be running generators on itself at  
runtime ?
