Şimdi, terminalde çıkış okur: "Menü Konum Ekleme Sorun." İşte benim populate_db.py senaryo. Benim traceback okur hariç/denemek çıkardıktan sonra https://docs.djangoproject.com/en/1.8/topics/db/examples/many_to_many/
: Sorun populate_db komut burada var olduğunu görüyoruz: m.location.add (l) Ama Bu sorgu burada verilen söz dizimi ile uyumludur :
TypeError: int() argument must be a string or a number, not 'Location'
Lütfen burada neler olduğunu açıklayın. Ve bir queryset aracılığıyla ManyToManyField için bir değer doğru bir şekilde nasıl eklenir.
Olası kopya: Django Error: TypeError: int() argument must be a string or a number, not 'BuildsTable' Yine de ManyToManyField kullandığım için durumumdaki cevabı bilmek istiyorum.

Lütfen tam geri izlemeyi gösterin. Eğer burada deneyin/çıkarmayı kaldırırsanız, bir tuple ile ilgili bir hata görmeyi beklerim, çünkü 'get_or_create'' döndürür (örnek, yaratılmış). –
