Rails - Jan 2010 - run 'script/generate controller' from inside app

Is it possible to run generator commands from within a running rails
application?

I''m experimenting with creating an application that can create
''views''
on the fly.

In my ''pages_controller.rb'' I have the following code:

    # Run Ruby script to create all pages defined in
''website_pages.txt''
    load "/railsprojects/#{Website.find(@page.website_id).name}/public/
build_pages.rb"

In my ''build_pages.rb'' I have the following code:

f = File.open("website_pages.txt", "r")
f.each_line do |page|
    ruby script/generate controller page
  end
file.close

The ''ruby script/generate controller page'' command fails. 
Does anyone
know how this line of code can be changed so that it will work?

Thanks,

Frank

Try this instead:

f.each_line do |page|
  %x[script/generate controller #{page}]
end
file.close

You can also invoke the generator by hand:

require ''rails/generators''
require ''generators/rails/controller/controller_generator''
Rals::Generators::ControllerGenerator.start %w(page),
{}, :destination_root => "path/to/tmp/dir"

Where :destination_root is the place you want to lay the generated
templates. You could put them in a temp directory and then zip/tar.gz
the directory''s content and send them.

This sounds like a bad idea, but if you really want to try it, then I 
think that running the generators is the wrong approach.  Remember that 
Ruby can programmatically define classes and methods.  That''s what you 
should be doing in this case.

You really shouldn''t be using a separate controller action for each
page
in this case.  Instead, have one controller action that takes the page 
name as a parameter.
