Django South Hata: AttributeError: 'DateTimeField' nesnesinin 'model''özellik yok'

Question

Bu yüzden bir tabloya iki sütun ekleyerek geçiş yapmaya çalışıyorum. Bir startDate ve bir endDate. Django için south'u kullanarak, bu basit bir geçiş olmalıdır. Ben de bunlarla birlikte dateTimes ile diğer tabloların bir sürü var, ama neden ve burada alıyorum ve burada görmüyorum.

yığın izleme belirten edilir: Burada

AttributeError: 'DateTimeField' object has no attribute 'model' 

Ben da taşıma modelidir: startDate ve endDate hariç

# Keep track of who has applied for a Job 
class JobApply(models.Model): 
    job = models.ForeignKey(Jobs) 
    user = models.ForeignKey(User) 
    # Keep track of the Developer accepted to do the work 
    accepted_dev = models.IntegerField(null=False, blank=False, default=0) 
    # If 1 (True) the User has applied to this job 
    isApplied = models.BooleanField(default=0) 
    startDate = models.DateTimeField() 
    endDate = models.DateTimeField() 

Tüm alanlar zaten VT var. Yani bu sütunları vermek için her şeyi kare tutmak için terminal aracılığıyla datetime.date.now() kullandığım varsayılan değerler. Sorun şu ki Güney'in schemamigration çalışması sadece iyi çalışıyor, ama gerçek göçmen barfs.

Hata gören herkes varsa, saçlarım buna değer. : P

Ben benim sürümünü yükseltmek zorundaiçin south sürümü 0.8.4 sürümünde. pip kullanılıyorsa,

sudo easy_install -U South 

Veya: Bundan sonra

pip install South --upgrade 

beklendiği gibi benim göç çalıştı

aşağıdaki komutu çalıştırın zorunda kaldı.
