Just started on Whoosh + Haystack.

I tested a test model which indexed fine and gave results. But indexing fails for some unknown reason on the second model (the important one)

Here is the model

class Sale(models.Model):
    brand = models.ForeignKey('Brand', related_name='sales_p')
    outlets = models.ManyToManyField('Outlet', null=True, blank=True, related_name='sales')
    child_brands = models.ManyToManyField('Brand', null=True, blank=True, related_name='sales_c')
    child_categories = models.ManyToManyField('Category', null=True, blank=True, related_name='sales_c')
#collecting subcategories for subcategory sale
    child_subcategories = models.ManyToManyField('SubCategory', null=True, blank=True,related_name='subcategory')

The search index for this is 

class SaleIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    outlets = indexes.CharField(model_attr='outlets')
    child_brands = indexes.CharField(model_attr = 'child_brands')
    child_categories = indexes.CharField(model_attr = 'child_categories')
    child_subcategories = indexes.CharField(model_attr = 'child_subcategories')
    content_auto = indexes.CharField(model_attr='brand')

    def get_model(self):
        return Sale

    def index_queryset(self, using=None):
        return Sale.objects.all()

    def prep_childbrands(self, object):
        return [brand.name for brand in self.child_brands.all()]

No one else in the world seems to have faced this ever. Am new to programming in general. Is there something I am missing that is obvious?

Traceback if that helps:

  • After a lot of fiddling I can say that the error is only thrown when indexing the manytomany field entries. If I only try to index the foreignkey field (named brand above) then the indexing seems to proceed correctly. – Kunstructor Apr 23 '15 at 17:11

There seems to be a bug in Haystack + Django 1.7 that is causing this error. This is also referenced in this other question which I had not noticed because of the Xapian mention (we are using Whoosh)

Django-haystack with xapian engine: can't execute update_index if model has ManyToManyField
