Solve the following python programming problem given the following code:
def has_permission(self, method, endpoint, user = None) : 
    "Return does the current user can access the resource.
        Example::

            @app.route('/some_url', methods=['GET', 'POST'])
            @rbac.allow(['anonymous'], ['GET'])
            def a_view_func():
                return Response('Blah Blah...')

        If you are not logged.

        `rbac.has_permission('GET', 'a_view_func')` return True.
        `rbac.has_permission('POST', 'a_view_func')` return False.

        :param method: The method wait to check.
        :param endpoint: The application endpoint.
        :param user: user who you need to check. Current user by default.
        " 
    app = self.get_app () 
    _user = (user or self._user_loader ()) 
    roles = _user.get_roles () 
    view_func = app.view_functions [endpoint] 
    return self._check_permission (roles, user, view_func) 

    
    

    Fix the buggy line: return self._check_permission (roles, user, view_func)

#Here is Python code to fix the buggy line: return self.

return self._check_permission (roles, method, view_func)
