autoComplete is now working

[wenzhi xue]

I have two modle here :

class StockSymbol(models.Model):
   symbol = models.CharField( max_length = 15 )
   exchange = models.CharField( max_length = 15, blank=True, null=True )
   companyName =  models.CharField( max_length = 40 )

   def __unicode__(self):
       return self.companyName

class WeatherLocation(models.Model):
   woeid = models.IntegerField()
   cityChar = models.CharField( max_length = 30,blank=True, null=True )
   stateChar =  models.CharField( max_length = 30, blank=True, null=True )

   def __unicode__(self):
       return self.cityChar

and I implement my index object like that :::

class WeatherLocationIndex(SearchIndex):
   text = CharField(document=True, use_template=True)
   stateChar =  indexes.CharField(model_attr='stateChar')
   cityChar = indexes.NgramField(model_attr='cityChar')

   def get_model(self):
       return WeatherLocation

   def index_queryset(self):
       """Used when the entire index for model is updated."""
       return WeatherLocation.objects.all()

   def get_queryset(self):
       return WeatherLocation.objects.all()

class StockSymbolIndex(SearchIndex):
   text = CharField(document=True, use_template=True)
   companyName =  indexes.CharField(model_attr='companyName')
   symbol = indexes.NgramField(model_attr='symbol')

   def get_model(self):
       return StockSymbol

   def index_queryset(self):
       """Used when the entire index for model is updated."""
       return StockSymbol.objects.all()

   def get_queryset(self):
       return StockSymbol.objects.all()

site.register(WeatherLocation, WeatherLocationIndex)
site.register(StockSymbol, StockSymbolIndex)

Then i did rebuild_index and go to django shell

My data here is "new york" and "new England"

but I can only get result if i do
>>> SearchQuerySet().filter(cityChar ='new')
[<SearchResult: rulesData.weatherlocation (pk=u'1')>, <SearchResult:
rulesData.weatherlocation (pk=u'3')>]

I can not get any result if i use "ne"  or simply "n"
>>> SearchQuerySet().filter(cityChar ='ne')
[]

any one can help me ?
