Scenario:
I instantiate a ModelForm and pass it to a template which displays the
form. When POST is submitted, code tries to search the database by any
of the given inputs. I dont require all inputs to be entered as in the
Model. I just need one (or more, if user desires to do an AND search)
to be entered.
Question: How can I make any of the ModelForm fields optional, where
in the Model, the field isnt optional. The field isnt optional in the
Model because I have another ModelForm based on the same Model, where
user is required to enter all his details.
My model:
class customer(models.Model):
# Need autoincrement, unique and primary
cstid = models.AutoField(primary_key=True, unique=True)
name = models.CharField(max_length=35)
age=models.IntegerField()
gender_choices = (('male', 'Male'),
('female', 'Female'))
gender = models.CharField(
choices=gender_choices, max_length=10, default='male')
maritalstatus_choices = ( ('married', 'Married'),
('unmarried', 'Unmarried'))
maritalstatus = models.CharField(
choices=maritalstatus_choices, max_length=10, default='Unmarried')
mobile = models.CharField(max_length=15, default='')
alternate = models.CharField(max_length=15, default='')
email = models.CharField(max_length=50, default='', blank=True)
address = models.CharField(max_length=80, default='', blank=True)
city = models.CharField(max_length=25, default='', blank=True)
occupation = models.CharField(max_length=25, default='', blank=True)
bloodgroup_choices = (('apos', 'A+'),
('aneg', 'A-'),
('bpos', 'B+'),
('bneg', 'B-'),
('opos', 'O+'),
('oneg', 'O-'),
('abpos', 'AB+'),
('abneg', 'AB-'),
('unspecified', '-')
)
bloodgroup = models.CharField(choices=bloodgroup_choices,
max_length=3, default='-', blank=True)
class Meta:
unique_together = ["name", "mobile", "age"]
def __str__(self):
return self.name
My form:
class CheckinPatientMetaForm(ModelForm):
class Meta:
model = customer
exclude = [
'gender',
'maritalstatus',
'occupation',
'bloodgroup'
]
views.py:
def checkin_patient(request):
results = ''
if request.method == 'POST':
form = CheckinPatientMetaForm(request.POST)
print("POST data",request.POST)
else:
form = CheckinPatientMetaForm()
return render(request, 'clinic/checkin.html', {'rnd_num':
randomnumber(), 'form': form, 'SearchResults': results})
