Diplay ModelForm in html - django

Question

I am creating a webapp in which a user can create a project, inside each project he can answer a set of question(in my app, I call them secondquestions).
I am trying to use ModelForm to ease the creation of the form by following this guide: https://docs.djangoproject.com/en/2.2/topics/forms/modelforms/
Howver I do not understand how I can display in my html my form.
secondquestions/views.py
def secondquestionstoanswer(request, project_id):
project = get_object_or_404(Project, pk=project_id)
if request.method == "POST":
form = SecondquestionForm(request.POST)
if form.is_valid():
form.save()
return render(request, 'secondquestions/secondquestionstoanswer.html', {'project':project})
secondquestions/models.py
from django.db import models
from django.contrib.auth.models import User
from django.conf import settings
from projects.models import Project
from django.db import models
from django.forms import ModelForm
class Secondquestion(models.Model):
second_one = models.TextField()
second_two = models.TextField()
second_three = models.TextField()
second_four = models.TextField()
second_five = models.TextField()
second_six = models.TextField()
second_seven = models.TextField()
second_eighth = models.TextField()
second_nine = models.TextField()
developer = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
project = models.OneToOneField(Project, on_delete=models.CASCADE)
class SecondquestionForm(ModelForm):
class Meta:
model = Secondquestion
fields = ['second_one', 'second_two', 'second_three', 'second_four', 'second_five', 'second_six', 'second_seven', 'second_eighth', 'second_nine']
secondquestions/secondquestionstoanswer.html
{% extends 'base.html' %}
{% block title %}First set{% endblock %}
{% block content %}
<form method="post">
{% csrf_token %}
{{ form }}
<button type="submit">Submit</button>
</form>
{% endblock %}
My problem:
In my html I just see the Submit button, not the form.

Answer 1

You never constructed a form that you passed to the template engine.
from django.shortcuts import redirect
def secondquestionstoanswer(request, project_id):
project = get_object_or_404(Project, pk=project_id)
if request.method == "POST":
form = SecondquestionForm(request.POST)
if form.is_valid():
form.instance.project = project
form.save()
return redirect('some_view')
else:
form = SecondquestionForm()
return render(
request,
'secondquestions/secondquestionstoanswer.html',
{'project':project, 'form': form}
)
With 'some_view', the name of the view to where you want to redirect in case the submission is successful.
In your <form> you specify in the action="..." attribute where what endpoint should be triggered, like:
<form method="post" action="{% url 'view_name_of_second_question' project.pk %}">
{% csrf_token %}
{{ form }}
<button type="submit">Submit</button>
</form>

You need a forms.py file that will contain your Model Form
secondquestions/forms.py
from django import forms
from .models import Secondquestion
class SecondquestionForm(forms.ModelForm):
class Meta:
model = Secondquestion
fields = ['second_one', 'second_two', 'second_three', 'second_four', 'second_five', 'second_six', 'second_seven', 'second_eighth', 'second_nine']
