HStoreField reading broken from external script or console.

[Dario Deledda]

Bug Description

When you run from external script or console the reading of an HStoreField return a String instead a Dict.
for example: an object from a class like:

class Alert(models.Model):
  data = HStoreField(default={})

if you try:

a=Alert.objects.all()[0
type(a.data)

return <class 'str'> instead <class 'dict'>

Brief analysis

It seems that in the console or script init, the register_hstore it's not called.

WorkAround:

If you use for the init of the console or external script the following code:

sys.path.append(gDjangoProjectPath)
os.environ["DJANGO_SETTINGS_MODULE"] = gDjangoSetting
django.setup()
from django.contrib.postgres.fields import HStoreField
from wot.apps.website.alert import Alert

# HSTORE BUG WORK AROUND!!
from django.db import connection
from psycopg2.extras import register_hstore
register_hstore(connection.connection)

the HStoreField work normally.

pip Freeze
