Hi,

@tools.ormcache is a decorator which helps to store dataset in memory cache. This is the methodology to manage cache for your functions.

For example there is method which calls every time when you reload any page at Odoo then every time it execute definition of that function. Due to this page takes to much time to load.

So in order to avid this issue Odoo introduces this decorator which stores the method response in memory cache. Then whenever someone trigger this method then instead of executing definition of this method it takes the response directly from cache.

Example:

@api.model
@tools.ormcache('self.env.cr.dbname')
def get_setting(self):
    return int(
		self.env['ir.config_parameter'].sudo().get_param('demo.setting',0)

)

Now in case you change setting then you can clear cache in write function using "clear_cache()",

def write(self, vals):
    res = super(IrConfigParameter, self).write(vals)
    self.get_setting.clear_cache(self.filtered(lambda r: r.key == 'demo.setting))
    return res

Feel free to ask in case of any confusion,
