CarePlans forms

Careplan has:
- condition_name: string
- privacy_settings: integer
- start_date: date
- treatments[]: Array

Treatments are build using form which are mapped to the DB. The base for the rest of care_plans is Treatment form:

class Treatment(models.Model):
    duration = models.DateField(blank=True, null=True)
    prescribed_by = models.TextField(blank=True, null=True)
    plan_details = models.TextField(blank=True, null=True)
    length = models.IntegerField(blank=True, null=True)
    length_unit = models.TextField(blank=True, null=True)
    condition = models.ForeignKey(Condition, related_name='treatments')

    class Meta:
        db_table = 'treatments'
        app_label = 'miamiApp'

    def as_json(self):
        return dict(
            condition=self.condition,
            diagnosis_date=self.diagnosis_date,
            duration=self.duration,
            privacy=self.privacy,
            prescribed_by=self.prescribed_py,

            length=self.length,
            length_unit=self.length_unit
        )

The other care_plans models:

    session_length_unit = models.TextField(blank=True, null=True)
