logging in odoo

Logging in odoo is very important thing in order to know what is happening in odoo server and to tracking any process in the server , and to make logging in odoo we have 2 steps

• Import logging in odoo class just like
  

  _logger = logging.getLogger(__name__)

• use type of logging in odoo which has many types just as
  
  INFO Logging : to log info message
  _logger.info("Any thing you want to log it")
  
  WARNING Logging : to log WARNING message
  _logger.warring("Any thing you want to log it")
  
  DEBUG Logging : to log DEBUG message
  _logger.debug("Any thing you want to log it")
  
  ERROR Logging : to log ERROR message
  _logger.error("Any thing you want to log it")
  
  CRITICAL Logging : to log CRITICAL message
  _logger.critical("Any thing you want to log it")
  
  
  Now let us Give an example and say that we want to log the current company name and the current user name , so
  we will inherit res.company name and add our logger in it as bellow
  
  
  class LoggerLogger(models.Model):
      _inherit = 'res.company'
  
      def odoo_logger(self,current_company,current_user):
          """
              Function To make logging for company and uers
          """
          _logger.info("Current Company : "+current_company+", The Current User : "+current_user)
  
  
  and when we call this function we have to pass company and user such as
  
  
     def logger_caller(self):
          current_company = self.env.user.company_id.name
          current_user = self.env.user.name
  
          self.env.user.company_id.odoo_logger(current_company,current_user)
