missing custom class

Trying to make my own analyzer I got this error : The type is set to custom, but can’t be instanciated… because it’s missing. I made something wrong?

/home/workspace/eggs/elasticsearch_dsl-0.0.8-py2.7.egg/elasticsearch_dsl/analysis.pyc in _type_shortcut(cls, name_or_instance, type, **kwargs)
    109         if type is None:
    110             type = 'custom'
--> 111         return cls.get_dsl_class(type)(name_or_instance, **kwargs)
    112 
    113 class Analyzer(AnalysisBase, DslBase):

/home/workspace/eggs/elasticsearch_dsl-0.0.8-py2.7.egg/elasticsearch_dsl/utils.pyc in get_dsl_class(cls, name)
    194             return cls._classes[name]
    195         except KeyError:
--> 196             raise UnknownDslObject('DSL class `%s` does not exist in %s.' % (name, cls._type_name))
    197 
    198     def __init__(self, **params):

UnknownDslObject: DSL class `custom` does not exist in token_filter.

Thanks! This error is definitely misleading and should be fixed. What is going on, however, is that you are not passing in the filter but just it’s name. There is then no way for the analyzer (autocomplete) to know where to take the autocomplete_filter you refer to. Correct way is to pass the token filter itself, not its name.

I am sorry @thavidu, I completely missed your question here. Please see #328 which is exactly the same issue.
