Supersedes #766

[Copilot]

Pull Request Overview

Adds validation to ensure the fields attribute on translation options isn’t accidentally provided as a single string and includes a test to cover that error case.

• Introduce a check in FieldsAggregationMetaClass to raise ImproperlyConfigured if fields is a str
• Add a user-friendly error message with a code hint via textwrap.dedent
• Add a test verifying that passing a string to fields raises ImproperlyConfigured

modeltranslation/translator.py:3

• The exception class ImproperlyConfigured is not imported in this file. Add an import, for example: from django.core.exceptions import ImproperlyConfigured to avoid a NameError when raising the exception.

from textwrap import dedent

modeltranslation/tests/tests.py:8

• You reference ImproperlyConfigured in the test, but it isn’t imported. Add from django.core.exceptions import ImproperlyConfigured (or the correct module) so pytest.raises(ImproperlyConfigured) works.

from modeltranslation.translator import TranslationOptions
