When I try to save in the admin, I get:

TypeError: 'MyModelName' object is not subscriptable

affected line is: e = self.model(None, None, user_id, content_type_id, smart_text(object_id), object_repr[:200], action_flag, change_message)

I dropped back down to Django 1.4.5 and the form works just fine now

class CountryNameInline(admin.TabularInline):
    model = GlobalCountriesNames
    extra = 1

class CountryAdmin(admin.ModelAdmin):
    list_display = ('countrycode', 'country_name', 'primary_lang_id', 'active')
    list_display_links = ('countrycode', 'country_name')
    inlines = [CountryNameInline, ]

class GlobalLanguages(models.Model):
    lang_id = models.CharField(max_length=2,
                               verbose_name=_('Language ID'),
                               help_text=_('ISO 639-1 2 letter language code - see: <a href="" target=_blank></a>'))
    lang_name = models.CharField(max_length=30,
                                 verbose_name=_('Language Name'),
                                 help_text=_('Use the language name in it\'s native language'))
    active = models.BooleanField(default=True,
    created = models.DateTimeField(auto_now_add=True,
    modified = models.DateTimeField(auto_now=True,

    def __unicode__(self):
        return self.lang_name

    class Meta:
        verbose_name = _('Language')
        verbose_name_plural = _('Languages')
        permissions = (('can_add_edit_languages', _('Can Add or Edit Languages')))

class GlobalCountries(models.Model):
    countrycode = models.CharField(max_length=2,
                                   verbose_name=_('Country Code'))
    primary_lang_id = models.ForeignKey(GlobalLanguages)
    active = models.BooleanField(default=True,
    created = models.DateTimeField(auto_now_add=True)
    modified = models.DateTimeField(auto_now=True)

    class Meta:
        verbose_name = _('Country')
        verbose_name_plural = _('Countries')
        permissions = (('can_add_edit_countries', _('Can Add or Edit Countries')))

    def _get_country_name(self):

        countryname = GlobalCountriesNames.objects.get(country_id=self.countrycode,
        if countryname is None:
            countryname = GlobalCountriesNames.objects.get(country_id=self.countrycode,
        return unicode(countryname)

    country_name = property(_get_country_name)

    def __unicode__(self):
        return self.country_name

    country_id = models.ForeignKey(GlobalCountries,
    lang_id = models.ForeignKey(GlobalLanguages,
    country_name = models.CharField(max_length=120,
                                   verbose_name=_('Country Name'))

I cannot reproduce your issue (I tried with both version 1.5 and the latest one).

The problem you describe seems to arrise when creating a LogEntry object corresponding to the creation of your model.
The error message indicates that your model's __unicode__ method returned an instance of MyModelName rather than the expected unicode string, which is not consistent with the code you pasted.

In consequence, I'm marking this issue as invalid. Please re-open it and provide:

  • The full error traceback
  • The actual code that triggers the error (the more you can simplify this code, the easier it is for someone to review this ticket)
