New issue 102 by paddyjoy: Error when evolving from IntegerField to
FloatField
http://code.google.com/p/django-evolution/issues/detail?id=102
What steps will reproduce the problem?
1. Create sample project and enable django-evolution
2. Create simple model
class Author(models.Model):
name = models.CharField(max_length=50)
email = models.EmailField()
date_of_birth = models.DateField()
age = models.IntegerField()
3. Run syncdb
4. Modify model and change Integer to Float
class Author(models.Model):
name = models.CharField(max_length=50)
email = models.EmailField()
date_of_birth = models.DateField()
age = models.FloatField()
5. Run python manage.py evolve --hint
What is the expected output? What do you see instead?
Expected output is to see evolution hint, instead an eror is produced:
joytech:/var/django/evolution_test# python manage.py evolve --hint
