Django DetailView page - inline formset not saved in SQL
I am trying to implement Django inline formset to my DetailView. According to documentation it is much better to separate Detail and Form views and bring them back together in the third view and this is what I did. My form is visible in my template file but after submission, nothing happens. It is returning correctly to my product detail view but no data is saved to SQL. Can you please let me know what am I doing wrong? models.py class Product(models.Model): title = models.CharField('title', max_length=400, blank=False, null=False, help_text='max 400 characters', default='') class CERequest(models.Model): author = models.CharField(max_length=255, blank=True, null=True) related_component = models.ForeignKey(CostCalculator, on_delete=models.CASCADE, blank=True, null=True, default=1) number_of_units = models.IntegerField(default=0) related_product = models.ForeignKey(Product, on_delete=models.CASCADE, null=True, blank=True, related_name='related_product_ce_request') created = models.DateTimeField(default=timezone.now) total_price = models.IntegerField(verbose_name='Price (€)', default=0, blank=True, null=True) forms.py class CalculatorFormProduct(forms.ModelForm): author = forms.CharField(widget = forms.HiddenInput(), required = False) number_of_units = forms.IntegerField(help_text='Only numeric values are allowed.', min_value=0) total_price = forms.IntegerField(widget = forms.HiddenInput(), required = False) created = forms.DateTimeField(widget = forms.HiddenInput(), required = False) class Meta: model = CERequest fields = ('author', 'created', 'related_product', 'related_component', 'number_of_units') CalculatorFormsetProduct = inlineformset_factory(Product, CERequest, form=CalculatorFormProduct, fields=('author', 'related_product', 'related_component', 'created', 'number_of_units'), extra=3, can_delete=False) views.py class ProductView(LoginRequiredMixin, DetailView): model = Product template_name = 'hubble/ProductDetailView.html' def get_success_url(self): return reverse('product', kwargs={'slug': … -

How to run parallel tasking with celery django?
I am looking to run tasks in parallel with django celery. Let's say the following task: @shared_task(bind=True) def loop_task(self): for i in range(10): time.sleep(1) print(i) return "done" Each time a view is loaded then this task must be executed : def view(request): loop_task.delay() My problem is that I want to run this task multiple times without a queue system in parallel mode.

Matching data from two functions in django context?
I'm struggling with matching contexts in my django project. I want to insert a .annotate() queryset, perfectly in just a set variable. I know it sounds weird but it's the best as I can describe it.

Gunicorn Django response statusText missing
I have a Django DRF/React setup using React and JWT for authorisation. On local runserver, I send the request for token, I recieve access and refresh tokens. When the access token expires, I have an Axios interceptor set which checks the error response and sends new response with refresh token. All passes and works fine. if ( error.response.data.errors[0].code === "token_not_valid" && error.response.status === 401 && error.response.statusText === "Unauthorized" ) { I noticed on server (Gunicorn), that the process all works fine, access token received and works as expected until expiry, but the refresh token request doesn't even send. Then after some debugging I noticed the gunicorn server sends the same response but without statusText. I am only assuming it is something to do with Gunicorn as that is the only difference than running code on runserver locally. On image, Left side is local response. Right side is server response. Any reason I would not receive the statusText? Any setting I need to be aware of? -

Django bulk update/replace substring keeping the previous value
I have a model with two fields: field_a and field_b field_a field_b JPY 6 blabla JPY 677 blabla I would like to replace / update the contents of field_a but keeping the old values (numbers) and just changing the currency.

Any help would be appreciated -
How to send an email through Sendgrid, as a reply to some email I received through Sendgrid inbound parse using Django?
So I am sending my email using sendgrid personalization something like this: message = { "personalizations": context["personalizations"], "from": {"email": context["sender_email"]}, "subject": context["subject"], "content": [{"type": MimeType.html, "value": context["body"]}], "reply_to": {"email": context["reply_to"]} } sg = SendGridAPIClient(os.environ.get("SENDGRID_API_KEY")) sg.send(message) Here context["personalization"] is an object as below: { "to": [{"email": applicant.email}], "custom_args": { "email_id": str(correspondance.id), "env": settings.ENVIRONMENT } } Sending and receiving the emails work fine. The problem is that I can't send an email as a reply to some email. Like a user sends me an email which I receive through sendgrid's inbound parse. Now I want to reply to the email I received. A solution I found on the internet was that I have to add an 'in_reply_to' ID which I receive as Message_ID in inbound parse but that didn't work. I did something like this: message = { "personalizations": context["personalizations"], "from": {"email": context["sender_email"]}, "subject": context["subject"], "content": [{"type": MimeType.html, "value": context["body"]}], "reply_to": {"email": context["reply_to"]}, "in_reply_to": message_id } sg = SendGridAPIClient(os.environ.get("SENDGRID_API_KEY")) sg.send(message) Here the message_id is Message_ID I received in the inbound email's json. -
