Haystack tweaks for Django 1.7.7. I had to upgrade to Haystack 2.3.1 to get it to work with Django 1.7.7. I also had to update the Xapian backend. But I ran into problems. On my laptop anyway (Ubuntu 14.0.4), xapian gets mad when search terms are greater than 245 chars (or something) when indexing. So I created a custom field that would simply omit terms greater than 64 chars and used this field everywhere I previously used a CharField. Secondly, the custom search form was broken now. Something changed in the Xapian backend and exact searches stopped working. Fortunately the auto_query (which I was using originally and broke during an upgrade) started working again. So I cut the search form back over to doing an auto_query. I kept the form the same (3 fields) because I didn't want to change the form and I think it's better that way.

from django.contrib import admin
from django.contrib.flatpages.models import FlatPage
from django.contrib.flatpages.admin import FlatPageAdmin as FlatPageAdminOld
from django.conf import settings

class FlatPageAdmin(FlatPageAdminOld):
    class Media:
        js = settings.GPP_THIRD_PARTY_JS['tiny_mce']

# We have to unregister it, and then reregister
admin.site.unregister(FlatPage)
admin.site.register(FlatPage, FlatPageAdmin)
