Django form in form - django

Question

I wonder if it is possible to make form in form by using django.
For example:
class Category(models.Model):
title = models.CharField(max_length=200)
icon = models.ImageField(upload_to="icons", default="icons/dot.png")
def __str__(self):
return self.title
def get_posts(self):
return Post.objects.filter(category__title=self.title)
class Post(models.Model):
author = models.ForeignKey(Account, on_delete=models.CASCADE)
title = models.CharField(max_length=200)
category = models.ForeignKey(Category, on_delete=models.CASCADE)
description = models.CharField(max_length=400)
date_posted = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.title
While I was working with forms based on these models I was splitting CategoryForm and PostForm into two forms (category had to be made before post to make user able to choose new category during making new post) and then into two views.
class PostForm(forms.ModelForm):
class Meta:
model = Post
exclude = ('author',)
class CategoryForm(forms.ModelForm):
class Meta:
model = Catergory
fields = '__all__'
def newPostView(request):
if request.method == 'POST':
form = PostForm(request.POST)
if form.is_valid():
obj = form.save(commit=False)
obj.author = request.user
obj.save()
return redirect('home')
form = PostForm()
context = {'form':form}
return render(request, 'blog/post_form.html', context)
def newCategoryView(request)
...
...
...
I'd like to make one newPost form which will have Category form implemented - I mean I'd like to be make it possible to choose category from already made categories or make new one if its needed without using another view
How can I make it ?
