Need Help in django form widgets - django

Question

I am in a middle of a project. I need help in using widgets. I have a Model for which i want a model form :
My model is :
class Appointments(models.Model):
doctor = models.ForeignKey(Doctor, on_delete=models.CASCADE)
patient = models.ForeignKey(Patient, on_delete=models.CASCADE)
app_time = models.DateTimeField()
diognoses = models.TextField(max_length=1000, null=True, blank=True)
prescriptions = models.TextField(max_length=250, null=True, blank=True)
class Meta:
unique_together = ('doctor', 'patient', 'app_time')
def __str__(self):
st = str(self.patient.user.name)+str(self.doctor.user.name)
return st
The corresponding model form is :
class AppointmentBookForm(forms.ModelForm):
app_time = forms.DateTimeField(widget=forms.SplitDateTimeWidget())
class Meta:
model = Appointments
fields = ['doctor','app_time']
Now for app_time I have split the date and time field which is already working fine.
Now I want a dropdown for date and a suitable widget for time.
The time should contain only hours and minutes.
And Finally I also want to provide the options for timing depending on the date and doctor.

Answer 1

For plain html the easiest way might be to define two input fields, one for the time and one for the date.
Input type="date":

Input type="time":

There are multiple results to this, here is one proposal:
models.py
from datetime import datetime
class Appointments(models.Model):
doctor = models.ForeignKey(Doctor, on_delete=models.CASCADE)
patient = models.ForeignKey(Patient, on_delete=models.CASCADE)
time = models.TimeField()
date = models.DateField()
app_time = models.DateTimeField()
diognoses = models.TextField(max_length=1000, null=True, blank=True)
prescriptions = models.TextField(max_length=250, null=True, blank=True)
def save(self, *args, **kwargs):
self.app_time = datetime.combine(self.date, self.time)
super().save(*args, **kwargs)
class Meta:
unique_together = ('doctor', 'patient', 'app_time')
def __str__(self):
st = str(self.patient.user.name)+str(self.doctor.user.name)
return st
forms.py
class AppointmentBookForm(forms.ModelForm):
class Meta:
model = Appointments
fields = ['doctor', 'time', 'date']
"""
# Optional: Define dedicated types or classes for the single fields
widgets = {
'time': forms.DateField(attr={"class": "myclass", "type": "time"})
}
"""
The app_time is quite redundant in this case. You could also define a property to receive the datetime:
class Appointments(models.Model):
doctor = models.ForeignKey(Doctor, on_delete=models.CASCADE)
patient = models.ForeignKey(Patient, on_delete=models.CASCADE)
time = models.TimeField()
date = models.DateField()
diognoses = models.TextField(max_length=1000, null=True, blank=True)
prescriptions = models.TextField(max_length=250, null=True, blank=True)
#property
def app_time(self):
return datetime.combine(date, time)
class Meta:
unique_together = ('doctor', 'patient', 'time', 'date')
def __str__(self):
st = str(self.patient.user.name)+str(self.doctor.user.name)
return st
example:
appointment = Appointments.objects.first()
print(appointment.app_time)
Alternatively, use some nice front end framework if you want to keep a single datetimefield.
