spell check with haystack

Question

I am getting None in spell check

first i made changes in settings.py

HAYSTACK_CONNECTIONS = {
    'default': {
        'ENGINE': 'haystack.backends.solr_backend.SolrEngine',
        'URL': 'http://127.0.0.1:8983/solr',
        'INCLUDE_SPELLING': True,
    },
}

made changes in search_indexes.py

class JobIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    post_type = indexes.CharField(model_attr='post_type',faceted=True)
    job_location = indexes.CharField(model_attr='job_location',faceted=True)
    job_type = indexes.CharField(model_attr='job_type',faceted=True)
    company_name = indexes.CharField(model_attr='company_name',faceted=True)
    job_title = indexes.CharField(model_attr='job_title', faceted=True)
    start_date = indexes.DateField(model_attr='start_date', faceted=True)
    end_date = indexes.DateField(model_attr='end_date', faceted=True)
    job_description = indexes.CharField(model_attr='job_description', faceted=True)
    country = indexes.CharField(model_attr='country', faceted=True)
    suggestions = indexes.FacetCharField()

    def prepare(self, obj):
        prepared_data = super(JobIndex, self).prepare(obj)
        prepared_data['suggestions'] = prepared_data['text']
        return prepared_data

    def get_model(self):
        return jobpost

    def index_queryset(self,**kwargs):
        return self.get_model().objects.all()

Then made solr_schema replaced it rebuild index..looked solrconfig.xml for appropriate chnages. Tested through django shell

>>> from haystack.query import SearchQuerySet
>>> sqs = SearchQuerySet().auto_query('spider')
>>> suggestion = sqs.spelling_suggestion()
>>> print suggestion
>>> None

Got None, can anyone help me?

You should rebuild your indexes using this command:

python manage.py rebuild_index

From the docs:

To work, you must set INCLUDE_SPELLING within your connection’s settings dictionary to True, and you must rebuild your index afterwards. Otherwise, None will be returned.
