First time poster, so go easy on me...
I need to create a form that will display a heading / description that
comes from one model (DReq) which I can get to display in a for loop.
Each dreq.desc is dependent on the results of a var that gets set and
read in from the user's session. Then I need to add a couple form
fields (from Saq) to each one that will relate to dreq.req_number
(also displayed alongside the desc) so that I can save the user's
input to the db (the DReq and MSaq are related as a MTM through
another model Saq).
The best way I can figure out how to do this is to use some sort of
for loop that will display each item and the respective form fields. I
have gotten that far by going the template route (see below). My
problem is that I do not know how to relate them to each other. Below
is some of what I have come up with. If all else fails I will just
create four (there are only four possible configurations for the form,
but it seems like this would be more elegant in a loop, somehow
relating them) individual forms to handle the task.
Here is what I have come up with so far (I know this together doesn't
work, it is just what I have tried in the various MTV places):
forms.py:
class MSForm(forms.Form):
answer = forms.Charfield(widget=forms.NullBooleanSelect)
note = forms.Charfield(widget=forms.TextArea)
# Perhaps use a ModelForm?
# class Meta:
# model = DReq
# fields = [
# 'answer',
# 'note',
# ]
views.py
@login_required
def saq(request):
current_saq = request.session.get('current_saq')
question = DReq.objects.filter(s_types=current_saq)
# Probably not the right place for the loop, but i was trying
something different
for dreq in question:
if question.headline:
req_headline = question.headline
req_number = dreq.req_num
if dreq.needs_answer:
saq_form = MSForm()
if request.method == 'POST':
saq_form = MSForm(request.POST)
if saq_form.is_valid():
# Query that pulls the requirement and assigns the correct
answer to it.
...
template.html -- This will display the form with the proper
information (from a different views.py version), but the form inputs
and the desc/reqs are not related in any way. Closest I've come except
it obviously doesn't work.
...
<form action="" method="post">{% csrf_token %}
<ul>
{% for dreq in question %}
{% if dreq.headline %}
<li>{{ dreq.headline }}</li>
{% endif %}
<li>{{ dreq.req_num }}: {{ dreq.desc}}</li>
{% if dreq.needs_answer %}
<div class="field">{{ saq_form.answer }}
{{ saq_form.note }}</div>
{% endif %}
{% endfor %}
</ul>
<input type="submit" value="Submit">
</form>
...
models.py
...
# This is where the desc text comes from
class DReq(models.Model):
req_num = models.CharField(max_length=5, blank=False)
headline = models.CharField(max_length=200, blank=True)
description = models.CharField(max_length=400, blank=False)
needs_answer = models.BooleanField(blank=False)
s_types = models.ManyToManyField(SType)
class MSaq(models.Model):
complete = models.BooleanField(blank=True)
d_req = models.ManyToManyField(DReq, through='Saq')
# This is where the data needs to be stored and related to
class Saq(models.Model):
d_req = models.ForeignKey(DReq)
m_saq = models.ForeignKey(MSaq)
answer = models.NullBooleanField(blank=False)
note = models.CharField(max_length=200, blank=True)
...
I have redacted some of the names to protect the innocent, I hope it
is still easy to follow. I feel like I am missing something very
basic, but I just can't wrap my head around what.
So, I just need to link the descriptions (which get iterated and
displayed just fine) to the form fields that get displayed with them,
so I can write the responses to the db. I hope this isn't info
overkill.
Thanks in advance.
