How to update all instances of a model for multiple models on the same page?
I am trying to update all instances of Goals and Competencies all at once, within the same page, using modelformset_factory. However, everytime I do that, it loads very weirdly such that goals formset will never be saved.

I think the form for goals is invalid, and I have no idea how to continue. I am new to Django and am wondering if I am doing this the wrong way with regards to updating all the instances of multiple model at the same time. models class Goals(models.Model): appraisal = models.ForeignKey(User_Appraisal_List, blank = False, null = True, on_delete=models.SET_NULL) summary = models.CharField(max_length = 150, blank = False, null = False) class Competencies(models.Model): appraisal = models.ForeignKey(User_Appraisal_List, blank = False, null = True, on_delete=models.SET_NULL) summary = models.CharField(max_length = 150, blank = False, null = False) class User_Appraisal_List(models.Model): STATUS_CHOICE = ( ('Employee', 'Employee'), ('Manager', 'Manager'), ('S2Employee', 'S2Employee'), ('S2Manager', 'S2Manager'), ('Approved', 'Approved') ) status = models.CharField(max_length = 30, blank = False, null = False, choices=STATUS_CHOICE) views.py def UpdateAppraisal(request, *args, **kwargs): id = kwargs.get('mk') selfappraisal = get_object_or_404(User_Appraisal_List, id=id) GoalsFormset=modelformset_factory(Goals, form = AppGoalsForm, extra … -

CSRF verification failed. Using Python Django backend and React, Axios(using POST) frontend
I am following this tutorial https://www.valentinog.com/blog/drf/ and succesfully finished it. I am trying to add a POST functionality to this tutorial. The thing is I am having trouble adding the POST command to send a csrf value using the Axios ajax framework. I have obtained the csrf on the cookies, and stored it in "csrfmiddlewaretoken" variable followed by a test message embedded in a json format to the axios function but it doesn't work resulting in a 403 error. I added @ensure_csrf_cookie decorator to the views.py but still the same error. Using the @csrf_exempt decorator on views.py solves this however I want to use csrf for security. csrftoken.js import React from "react"; function getCookie(name) { var cookieValue = null; if (document.cookie && document.cookie !== "") { var cookies = document.cookie.split(";"); for (var i = 0; i < cookies.length; i++) { var cookie = cookies[i].trim(); if (cookie.substring(0, name.length + 1) === name + "=") { cookieValue = decodeURIComponent(cookie.substring(name.length + 1)); break; } } } return cookieValue; } var csrftoken = getCookie("csrftoken"); const CSRFToken = () => { return <input type="hidden" name="csrfmiddlewaretoken" value={csrftoken} />; }; export default CSRFToken; App.js ... import axios from "axios"; import CSRFToken from "./csrftoken"; ... sendPost() { var … -

retrieve a coupon in stripe using python
I'm working on a project to create a subscription function for our products. I'm creating a function to check if the coupon code entered by the user matches the coupon.id in stripe if it does then it should store it in session else it should display "incorrect code" message. My code seems to be incorrect and is not working. Please help !!! views.py def retrieve_coupon(request): if request.method == 'POST': form = CouponApplyForm(request.POST) if form.is_valid(): code = form.cleaned_data['code'] try: coupon_id = stripe.Coupon.retrieve(code) request.session['coupon'] = code except coupon.DoesNotExist: messages.info(request, "This coupon does not exist") request.session['coupon'] = None context={ 'form':form } return render(request, "retrieve_coupon.html", context) forms.py class CouponApplyForm(forms.Form): code = forms.CharField() template <div class="divo"> <p> coupon code to apply discount </p> <form action="" method="post"> {% csrf_token %} {{ form }} <input type="submit" value="apply" class="btn"> <ul class="messages"> {% for message in messages %} <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li> {% endfor %} </ul> </form> </div>
