Hello, I've only just started with Django and need a bit of help steering
myself in the right direction.
I want to create a page that has a list of possible forms that could be
filled in for a patient in a medical study and differentiate between those
forms which have already been completed and those that have yet to be
started. I have 3 tables: 'Building' which contains the list of forms,
'Street' which contains the list of patients and 'Address' which records
which form exists for each patient. The relevant bit of models.py looks
like this:
class Building(models.Model):
crf_code = models.CharField(max_length=6, primary_key=True)
crf_name = models.CharField(max_length=100)
class Street(models.Model):
village = models.ForeignKey(Village)
patient_number = models.PositiveIntegerField()
initials = models.CharField(max_length=3)
class Address(models.Model):
street = models.ForeignKey(Street, related_name='addresses')
building = models.ForeignKey(Building, related_name='addresses')
completed = models.BooleanField(default=False)
I've created a view that creates two lists, one of all buildings (i.e.
forms that could be entered for a patient) and another of forms already
existing, filtered by patient id:
def street2(request, patientid):
context_dict = {}
try:
address = Address.objects.filter(street__pk=patientid)
crf = Building.objects.all()
context_dict['address'] = address
context_dict['crf'] = crf
except Street.DoesNotExist:
context_dict['address'] = None
context_dict['crf'] = None
return render(request, 'trial/street2.html', context_dict)
My problem comes with relating the two lists to each other in my template.
what I want to do is list the buildings and then, depending if the form
already exists, display an "edit form" or "create form" link:
<div>
<ul>
{% for x in address %}
<li>
<div>{{ x.building }}</div>
<div>
{% if ???? %}
link to edit form
{% elif %}
link to create form
{% endif %}
</div>
</li>
{% endfor %}
</ul>
</div>
I'm not sure if I've explained myself clearly; if not I apologize. I'm only
just starting out and am floundering a bit. Any help or guidance would be
hugely appreciated.
Thank you,
Richard
