Django modelformset_factory id is required field

I'm trying to create a table of records to update with a single click. I keep getting the error [{'id': ['This field is required.']}] I can't seem to figure it out. I have tried to put {{ form.label_tag }} in somewhere to see if that would help, but it doesn't. I can't figure out how to be sure id gets passed back in for the edit.

Comparing fields from two models using foreign key.(for displaying correct product under correct category) using django

I have two models Category and Product. Here is models.py
class Category(models.Model):
type=models.CharField(max_length=30)
def __str__(self):
return self.type
class Product(models.Model):
category = models.ForeignKey(Category, on_delete = models.CASCADE)
productid=models.CharField(max_length=30)
name=models.CharField(max_length=30)
disimage=models.ImageField(upload_to='pics')
def __str__(self):
return self.productid
In my template I have two for loops the outer one that iterates category model and the other that iterates through products and i want to display the product only if the category.type is equal to the product category (for example if there is a type=Shirt in category then I want display a product under it only if it has type=Shirt )
Here is my HTML
{% for i in types %}
<div class="container">
<div class="row product-btn d-flex justify-content-end align-items-end">
<!-- Section Tittle -->
<div class="col-xl-4 col-lg-5 col-md-5">
<div class="section-tittle mb-30" id="{{i.type}}">
<h2>{{i.type}}</h2>
</div>
</div>
</div>
<div class="tab-content" id="nav-tabContent">
<!-- card one -->
<div class="tab-pane fade show active" id="nav-home" role="tabpanel" aria-labelledby="nav-home-tab">
<div class="row">
{% for product in prods %}
{% if i.type == product.category %}
<div class="col-xl-4 col-lg-4 col-md-6">
<div class="single-product mb-60">
<div class="product-img">
<img src="{{product.disimage.url}}" alt="">
</div>
<div class="product-caption">
<h4>{{product.name}}</h4>
<div class="price">
<ul>
<li>RS {{product.currentprice}}</li>
<li class="discount">RS {{product.originalprice}}</li>
<div>
View
Add to Cart
</div>
</ul>
</div>
</div>
</div>
</div>
{% endif %}
{% endfor %}
</div>
</div>
</div>
</div>
</div>
{% endfor %}
I am trying to do this using {% if i.type == product.category %} but i am not succeeding. Any help on how to work this out will be appreciated.

you should use the following
{% if i.type == product.category.type %}

Django HTML for loop with filter

In my django project, I have an HTML that renders questions header, and inside the question headers I have question items. In my model, Question headers and items are two different entities. I need to show for every header, just the items related to that header. As it shows all items for all questions without any filters. Greatly appreciate any help!
Model:
class Question(models.Model):
question = models.CharField(max_length=240)
mission_section = models.ForeignKey('Mission_Section', on_delete=models.CASCADE)
type_question = models.ForeignKey('Type_Question', on_delete=models.CASCADE)
categories_question = models.ForeignKey('Categories_Question', on_delete=models.CASCADE, default=1)
order = models.IntegerField(default=1)
def __str__(self):
return self.question
class Question_Option(models.Model):
question = models.ForeignKey('Question', on_delete=models.CASCADE,default=1)
option = models.CharField(max_length=240)
correct = models.BooleanField()
order = models.IntegerField(default=1)
View:
class Questions(LoginRequiredMixin, FormView):
template_name = "questions.tmpl"
def get(self, request, pk):
context = {
'pk': pk,
'section': Mission_Section.objects.get(pk = pk ),
'questions_items': Question_Option.objects.filter(question__mission_section__pk=pk).order_by('order','pk'),
'questions': Question.objects.filter(mission_section__pk = pk ),
'question_types' : Type_Question.objects.all(),
'questions_categories': Categories_Question.objects.all()}
return render(self.request, self.template_name, context)

</div>
</div>
</div></li>
{% endfor %} </ol>

using this answer I figured it out Double loop in Django template
What I need is:
<div id = "question_content_{{question.id}}" name="question-options" class="collapse">
{% csrf_token %}
{{ form.as_p }}
<form class='ajax-form-option' id="form-option-{{question.id}}" method='GET' action='.' data-url='{{ request.build_absolute_uri|safe }}'>
<ol class="example list-group">
{% for qi in question.question_option_set.all %}
<li class="list-group-item d-flex justify-content-between align-items-center" id=option-{{qi.id}} name="opt-{{question.id}}-{{qi.id}}">
<div contenteditable="true">{{ qi.option }}</div>
<div>
<button type="button" name='option-check' class="btn btn-light" value={{qi.id}} id="check-option-{{question.id}}-{{qi.id}}">
<i class="fas fa-check"></i>
</button>
<button type="button" class="btn btn-warning" id="delete-option-{{question.id}}-{{qi.id}}" onclick="deleteOption({{qi.id}})">
<i class="fa fa-trash" aria-hidden="true"></i>
</button>

</li>
{% endfor %} </ol>
<div onclick="CreateOption({{question.id}})">

<div class="d-flex justify-content-center"> <br><i class="fa fa-plus-circle fa-1x" aria-hidden="true"></i></div>

You can access the related dogs with .dog_set.all:
{% for lostPost in lostPosts reversed %}
<h6>{{lostPost.id}}</h6>
{% for dog in lostPost.dog_set.all %}
<h6>{{dog.breed}}</h6><br>
…
{% endfor %}
{% endfor %}
In the view, you pass a queryset with .prefetch_related:
def lostList(request):
lostPosts = LostNotice.objects.prefetch_related('dog')
dogs=Dog.objects
return render(request, '/lostList.html', {'lostPosts' : lostPosts})
