I am looking the above answer and found a link , https://www.odoo.com/forum/help-1/question/is-it-possible-to-call-method-on-menu-65980 but i still this is not what i want ,

the scenario is this ,

  • i have a sale.lead with a method call process_daily_lead 
  • it is designed to be a scheduler function but i need this to be called ad-hoc for testing purpose and i do not wish to write a line of code , can i do it …
after much hacking for about half an hour , this is what i found out !
the magic lies here …
  • Menu and Server Actions only !
First ,
we need to set up at the Menu ,
and the server action setup is as follow , you should by right , create the server action 1st,
if you put a test code , e.g. print ‘i am here’ are the module py code , 
if everything goes , well , u will get an extra menu under sales/sales and when you click it
it will directly execute function.
