Description (last modified by Wael BEN ZID EL GUEBSI)

I want to store a tweet status in database, below the model definition

class Status(models.Model):
    raw = pgfields.HStoreField()
    # other fields

status = Status(raw=dict_object)

and I got this error:

ProgrammingError: ARRAY types integer and integer[] cannot be matched
LINE 1: ... 'id_str', 'screen_name', 'name'], ARRAY[9284062, ARRAY[3, 1...

below the data that I want to insert:

HStoreField (and the Postgres hstore type in general) can't store arbitrarily nested mappings of arbitrary types, only single level mappings of string to string (as noted in the first sentence of the HStoreField docs). You may want a JSONField instead.

Note: See TracTickets for help on using tickets.
