Description

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

admin.py:

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, ]

models.py:

class GlobalLanguages(models.Model):
    lang_id = models.CharField(max_length=2,
                               primary_key=True,

Hi,

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)

Thanks.
