Here's the write () method i want to restrict in my custom module. I don't want this existing write method to work how can I do that? 

class Product (models.Model):

    _name = 'product.product'

     @ api multi

def  write ( self ,  values ): 
'' 'Store the standard price change in order to be able to retrieve the cost of a product for a given date' '' 
res = super ( ProductProduct , self ). write ( values ) 
if 'standard_price' in values : 
    self . _set_standard_price ( values [ 'standard_price' ]) 
return res        
           
I can't comment this code as it belongs to the source model. I just want this function to bypass so it wont have any effect because i have written another method according to my requirement.
