django: Can't save data to the model, psql error

I have following model described:

class UserProfile(models.Model):
    avatar = models.ImageField(blank = True, upload_to='files')
    about = models.TextField(blank=True)
    rank = models.IntegerField(default = 1)
    solvedProblems = models.ManyToManyField(Composition, blank=True)
    user = models.ForeignKey(User, unique=True)
    country = CountryField(blank = True)
    status = models.ForeignKey(UserRank)

where UserRank is:

class UserRank(models.Model):
    rankName = models.CharField(max_length = 300)
    upLimit = models.IntegerField()
    downLimit = models.IntegerField()

I have added the status, country and avatar field later after describing model, so updated the database via sql.

Now database looks this way:

chess_problems=# \d registration_userprofile; Table "public.registration_userprofile" Column | Type | Modifiers

-----------+------------------------+----------------------------------------------------------------------- id | integer | not null default nextval('registration_userprofile_id_seq'::regclass) about | text | not null rank | integer | not null user_id | integer | not null avatar | character varying(100) | country | character varying(2) | status_id | integer | Indexes: "registration_userprofile_pkey" PRIMARY KEY, btree (id) "registration_userprofile_user_id_key" UNIQUE, btree (user_id) Foreign-key constraints: "registration_userprofile_status_id_fkey" FOREIGN KEY (status_id) REFERENCES registration_userrank(id) DEFERRABLE INITIALLY DEFERRED "registration_userprofile_user_id_fkey" FOREIGN KEY (user_id) REFERENCES auth_user(id) DEFERRABLE INITIALLY DEFERRED

The error code I see is:

(, DataError('value too long for type character varying(2)\n',), )

Traceback (most recent call last): File "/usr/lib/python2.5/site-packages/Django-1.1.1-py2.开发者_Go百科5.egg/django/core/servers/basehttp.py", line 280, in run self.finish_response() File "/usr/lib/python2.5/site-packages/Django-1.1.1-py2.5.egg/django/core/servers/basehttp.py", line 320, in finish_response self.write(data) File "/usr/lib/python2.5/site-packages/Django-1.1.1-py2.5.egg/django/core/servers/basehttp.py", line 416, in write self._write(data) File "/usr/lib/python2.5/socket.py", line 274, in write self.flush() File "/usr/lib/python2.5/socket.py", line 261, in flush self._sock.sendall(buffer) error: (32, 'Broken pipe')

I feel it happens because I incorrectly updated database to fit the model...But not sure what is wrong, and how to fix it. Same code works locally on mysql instance...But I have psql on prod....

I'm betting you're using this: http://djangosnippets.org/snippets/494/ and [as tcarobruce says] CountryField is a 2-char code that represents the country -- 'FR', 'GB', 'US' etc and you're trying to store the full string name of the country instead.
