How can I display an AutoField in a ModelForm?

[Joel Mathew]

Question: How can I display an AutoField in a ModelForm. I have a need
where a Form is generated and displayed. Based on the input, I need to
read the AutoField's value and search for it in my database.

My form:

class CheckinPatientMetaForm(ModelForm):
class Meta:
model = customer
exclude = [
'gender',
'maritalstatus',
'occupation',
'bloodgroup'
]

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

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})

Relevant part of my template:

<form class="" action="/clinic/checkin" method="post">
{% csrf_token %}
<div class="form-row">
<div class="col-md-24 mb-6">
<label for="cstid" id="lbl-cstid">Hospital ID</label>
{{ form.cstid|add_class:"form-control" }}
</div>
</div>
<div class="form-row">
<div class="col-md-24 mb-6">
<label for="Name">Name</label>
{{ form.name|add_class:"form-control" }}
</div>
</div>
<div class="form-row">

<div class="col-md-12 mb-3">

{{ form.alternate|add_class:"form-control" }}
</div>
</div>
<div class="form-row">
<div class="col-md-24">
<label for="Address" id="lbl-Address">Address</label>
{{ form.address|add_class:"form-control" }}
</div>

<div class="form-row">
<div class="col-md-24">

</div>
</div>
<div>
<input class="btn btn-primary btton-right" value="Search"
id="btnCheckinSearch" type="submit">
</div>
</form>

The generated html:

</div>
<div class="form-row">

<input type="text" name="city" maxlength="25"

</div>
<div>

</form>

As you can see, there is not input field for cstid. In the actual
model, it's an automatic field. But in the ModelForm it needs to be a
form input so I can search for a patient's hospitalid (which is this
automatic field). How can I display this field in the form?
