Hey there  
I would like to know if I can call a rake task from inside my Rails App.  
Something like

class MyModel \< ActiveRecord::Base  
after\_save :run\_task

def run\_task  
Rake.run(“my:little:task”)  
end  
end

This is the deal: I use thinking-sphinx and need to update a bunch of  
data  
through Model.update\_all. But I would like sphinx to index it just after  
I’m  
done, by running rake ts:index.

Is that possible?

Thanks,  
Dante

def run\_task  
result = %x(rake #{params[:rake\_task]})  
end

If you don’t want to hold the thread you can install the crontab gem  
and install a new crontab with a ts:in or use background-fu and push  
the job to the background…
