from django.db import models

```
class Developer(models.Model):
    name = models.CharField(max_length=21, null=False, blank=False)
    created = models.DateTimeField(auto_now_add=True)

    def __unicode__(self):
        return str(self.name)

```

models.py

```
from django.db import models

from developers.models import Developer

class Task(models.Model):
    story = models.ForeignKey(Story)
    developer = models.ForeignKey(Developer)
    description = models.CharField(max_length=360)
    iteration = models.IntegerField()
    created = models.DateTimeField(auto_now_add=True, auto_now=False)

```

forms.py 

```
class AddTask(forms.ModelForm):
    story = forms.ForeignKey(Story)
    developer = forms.ForeignKey(Developer)
    description = forms.CharField(max_length=360)
    iteration = forms.IntegerField()

    class Meta:
        fields = ["name", "developer", "description", "iteration"]
        model = Task

```
