Solve the following python programming problem given the following code:
@ wsgi.response (201) 
def create(self, req, body, gid) : 
    def _validate(context, body, gid) : 
        if (not self.is_valid_body (body, 'securitygroup')) : 
            msg = _ ('Invalid request body') 
            raise exception.InvalidInput (reason = msg) 
self._uuid_check (gid) 
        db.group_get_by_gid (context, gid) 
        values = body ['securitygroup'] 
        name = values.get ('name') 
        is_default = values.get ('is_default') 
        if is_default : 
            try : 
                is_default = strutils.bool_from_string (is_default, strict = True) 
except ValueError : 
                msg = _ ('is_default must be a boolean') 
                raise exception.InvalidInput (reason = msg) 
else : 
            is_default = False 
valid_values = { 
            
} 
        valid_values ['gid'] = gid 
        valid_values ['display_name'] = name 
        valid_values ['is_default'] = is_default 
        rules = values.get ('securitygrouprules') 
        valid_rules = [] 
        if (rules is not None) : 
            if (not isinstance (rules, list)) : 
                msg = _ ('securitygrouprules must be a list') 
                raise exception.InvalidInput (reason = msg) 
for rule in rules : 
                valid_rule = { 
                    
} 
                valid_rule ['protocol'] = rule.get ('protocol') 
                valid_rule ['port_range_max'] = rule.get ('port_range_max') 
                valid_rule ['port_range_min'] = rule.get ('port_range_min') 
                valid_rule ['remote_ip_prefix'] = rule.get ('remote_ip_prefix') 
                remote_securitygroup_id = rule.get ('remote_securitygroup_id') 
                if remote_securitygroup_id : 
                    ref = db.securitygroup_get_by_securitygroup_id (context, gid, remote_securitygroup_id) 
                    valid_rule ['remote_neutron_securitygroup_id'] = ref ['neutron_securitygroup_id'] 
valid_rules.append (valid_rule) 
return (valid_values, valid_rules) 
try : 
        context = req.environ...

    
    

    Fix the buggy line: securitygroup = db.securitygroup_create (context, securitygroup)
assistant
#Here is Python code to fix the buggy line: securitygroup = db.

securitygroup = db.securitygroup_create (context, values)
