Why celery is giving Database connection error even though database server has connection pooling active
Currently I am facing some problem regarding my web app. I have a web app built with django along with celery for some background task. The workflow is - client uploads an image and then some processing is done in celery task like some api call and some db update. Then client polls for result and if the task is done the result is given as response. I am using DigitalOcean managed postgresql db and using a connection pool. For celery message queue I am using rabbitmq and redis as backend result server. As most of my task is I/O bound I am using gevent for celery so that I can receive concurrent requests without any problem. My server has 2vcpu, 4GB RAM, 25GB SSD. At first when no connection pooling was activated in DB, we stress tested with around 100 image uploaded at the same time and got "FATAL: remaining connection slots are reserved for non-replication superuser connections". After some research found that this was due to db connection limit crossing, So I used connection pooling. Then there was no problem for django. But strangely celery was giving the same error while updating database. My celery command is (from … -

Actually I need suggestion about best practice to handle guest checkout and customer checkout. I have a scenario that 1 order can have multipul products (which is not problem). My order table is like class Orders(models.Model): customer= models.ForeignKey(Customer, on_delete=models.CASCADE) order_number = models.AutoField(primary_key=True) total_amount = models.DecimalField(max_digits=10, decimal_places=2) ordertime = models.DateTimeField(auto_now_add=True) order_status = models.CharField(max_length=50) is_placed = models.BooleanField(default=False) and then it is linked to product table like this class OrderProduct(models.Model): order=models.ForeignKey(Orders, on_delete=models.CASCADE) activity = models.ForeignKey(ActivityOrganizer, on_delete=models.CASCADE) participants=models.IntegerField(default=0) totalPrice=models.DecimalField(max_digits=10, decimal_places=2) checkIn = models.DateField() language = models.CharField(max_length=50, null=False, blank=False) And my Customer Table is class Customer(models.Model): customerProfile = models.OneToOneField(User, on_delete=models.CASCADE) first_name=models.CharField(max_length=50, null=False, blank=False) last_name=models.CharField(max_length=50, null=False, blank=False) email=models.CharField(max_length=50, null=False, blank=False) mobile_number=models.CharField(max_length=50, null=False, blank=False) profile_image=models.ImageField(null=True, upload_to='CustomerProfile') is_customer=models.BooleanField(default=False) city=models.CharField(max_length=50, null=True, blank=True) gender=models.CharField(max_length=50, null=True, blank=True) verification_key = models.CharField(max_length=100, null=True, blank=True) def __str__(self): return str(self.first_name) Now I want to Enable guest checkouts aswell . then Should I use existing tables of order by allowing Foregin key Null ?

Django 2.2 - change with of related auto_complete field on admin form
I'm trying to change the field width of a related auto_complete field. So that the selected record is shown a bit wider. <span class="select2 select2-container select2-container--admin-autocomplete select2-container--focus" dir="ltr" style="width: 260px;"> // ... ></span> I created my own form and tried fiddling with widget.attrs (inside the init) but it has zero effect. Which itself is no strange, since these are all span elements rendered. class OrderLineForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.fields['product'].widget.attrs.update({'stytle': 'width: 400px'}) self.fields['product'].widget.attrs.update({'width': 400}) I was also looking which widget is being used, but didn't find it either. Djanog docs do explainThe form.Select is a simple dropdown list, which does not provide auto complete functionality. I also tried changing some css for .select2 class, but seems to gave no effect. -
How to add extra field to django serializer?

I have a Model and a ModelForm. The ModelForm has a dependent dropdown list implemented with JQuery.

Django raw sql insert query in triple quotation: Django interprets null values from ajax request data as None column
I am working on a Django/React project. Using DRF, I am throwing an API route for performing SQL queries in my PostgreSQL database. But I am having issues with my current code setup. I have setup my INSERT query in the API as raw queries (using cursor) enclosed in a triple quote multi-line string """INSERT...""", then format my values using string formatting %s. In my API, I capture each request body into a variable. Everything works fine if all request data are filled. But, if it is null, Django obviously assigns None to the variable. Now back to my sql query, Django will treat the null %s as None and as a table column instead of a correct null value, thus throwing a ProgrammingError column "none" does not exist. Here are sample codes: React Frontend const [lastName, setLastName] = useState('') const [firstName, setFirstName] = useState('') const [middleName, setMiddleName] = useState('') const [nameExtn, setNameExtn] = useState('') const [sex, setSex] = useState('') const [civilStatus, setCivilStatus] = useState('') const [bloodType, setBloodType] = useState('') const [height, setHeight] = useState('') const [weight, setWeight] = useState('') const newPersonalInfo = (token, data) => { let endpoint = "/jobnet/api/profile/pds/basic/personal/" let lookupOptions = { method: "POST", headers: { 'Content-Type': … -

So, I'm trying to let the user be automatically logged in as soon as he/she registers. Here's my register function. def register(response): if response.method == 'POST': form = RegisterForm(response.POST) if form.is_valid: form.save() return redirect('/main/inputuserinfo') else: form = RegisterForm() return render(response, 'register/register.html', {'form' : form}) As I mentioned, I'd like to log the user in right after he/she registers, then redirect him/her to '/main/inputuserinfo'. But I have no idea on how I can create it. I very much appreciate your help. :)
