Django: AttributeError Объект 'WSGIRequest' не имеет атрибута 'get'

Я пытаюсь добавить набор встроенных форм, но когда я пытаюсь сохранить информацию форм, выдает ошибку

views.py

Намерение состоит в том, чтобы создать больше заказов для конкретного клиента, поэтому для достижения этой цели я ориентируюсь на функцию "createOrder".

from django.shortcuts import render, redirect

from django.http import HttpResponse
from .models import *
from django.forms import inlineformset_factory
from .forms import OrderForm, CustomerForm

# Create your views here.

def home(request):
    orders_value = Order.objects.all()
    customer_value = Customer.objects.all()
    
    total_orders_value = orders_value.count()
    total_customers_value = customer_value.count()

    pending_value = orders_value.filter(status='Pending').count()
    delivered_value = orders_value.filter(status='Delivered').count()

    context = {'orders_key': orders_value, 'customer_key': customer_value,
    'total_orders_key':total_orders_value, 'pending_key': pending_value, 
    'delivered_key': delivered_value}

    return render (request, 'accounts/dashboard.html', context)

def products(request):
    products_value = Product.objects.all()
    return render (request, 'accounts/products.html', {'products_key': products_value})

def customer(request, pk_test):
    customer_value = Customer.objects.get(id=pk_test)
    orders_value = customer_value.order_set.all()
    orders_value_count = orders_value.count()
    context = {'customer_key':customer_value, 'orders_key': orders_value, 'orders_key_count': orders_value_count}
    return render (request, 'accounts/customer.html', context)

def createOrder(request, pk):
    OrderFormSet= inlineformset_factory(Customer, Order, fields=('product', 'status'))
    customer = Customer.objects.get(id=pk)
    form_set_value= OrderFormSet(instance=customer)
    if request.method == 'POST':
        form_set_value= OrderFormSet(request, instance=customer)
        if form_set_value.is_valid:
            form_set_value.save()
            return redirect('/')
    context = {'form_set_key':form_set_value}
    return render(request, 'accounts/order_form.html', context)

order_form.html

{% extends 'accounts/main.html' %}
{% load static %}
{% block content %}

<form action="" method="POST">
    {% csrf_token %}
    {{ form_set_key.management_form }}
    {% for form in form_set_key %}
        {{form}}
    <hr>
    {% endfor %}
    <input type="submit" name="Submit">

    email = models.CharField(max_length=200, null=True)
    data_created = models.DateTimeField(auto_now_add=True, null=True)
    
    def __str__(self):
        return self.name
class Tag(models.Model):
    name = models.CharField(max_length=200, null=True)
    
    def __str__(self):
        return self.name 

class Product(models.Model):
    CATEGORY = (
            ('Indoor', 'Indoor'),
            ('Out Door', 'Out Door'),
            ) 
    
    name = models.CharField(max_length=200, null=True)
    prince = models.FloatField(null=True)
    category = models.CharField(max_length=200, null=True, choices=CATEGORY)
    description = models.CharField(max_length=200, null=True, blank=True)
    data_created = models.DateTimeField(auto_now_add=True, null=True)
    tags = models.ManyToManyField(Tag)

    def __str__(self):
        return self.name

class Order(models.Model):
    STATUS = (
            ('Pending', 'Pending'),
            ('Out for delivery', 'Out for delivery'),
            ('Delivered', 'Delivered'),
            )
    
    customer = models.ForeignKey(Customer, null=True, on_delete=SET_NULL)
    product = models.ForeignKey(Product, null=True, on_delete=SET_NULL)
    status = models.CharField(max_length=200, null=True, choices=STATUS)
    data_created = models.DateTimeField(auto_now_add=True, null=True)

    def __str__(self):
        return self.product.name

Я думаю, что это связано с тем, как информация управляется из шаблона, но я не совсем уверен. Кто-нибудь может мне помочь?

OrderFormSet(request, instance=customer)

OrderFormSet(request.POST, instance=customer)
