Google file picker API giving error Javascript
I am trying to implement a google file picker in my Django Project. Currently when I try to create an HTML page with Google file picker integrated I am facing 500 Something went wrong error. This happens after I authorize my app and create access token. First I was thinking that access token generation must be having some issues, but I tried listing files using the access token generated and I was able to successfully list down files in my Google drive as can be seen in the browser console. Help will be greatly appreciated.

Django 3.2 CITEXT and unique_together
I'm using Django 3.2 and postgreSql 12. I've added a new text field that should be case-insensitive, i.e if the value 'ab' exists, I want the DB to fail the request if someone is inserting 'Ab'. But this field shouldn't be unique all over the table, but unique with another field (unique_together). I've tried creating the field as 'CITEXT' and since it's deprecated in Django 4.2 I've used the Collation migration as recommended. The migrations passed, and when testing it I see that I can create two objects with the same letters, and different cases. Am I doing something wrong or this implementation of case-insensitive shouldn't work with 'unique_together'? The collation migration: operations = [ CreateCollation( "case_insensitive", provider="icu", locale="und-u-ks-level2-kn-true", deterministic=True, ), ] The model changes: class MyItem(models.Model): identifier = models.CharField(db_collation="case_insensitive", db_index=True, max_length=100, null=True) container = models.ForeignKey(Container, related_name='my_items', on_delete=models.CASCADE, null=True) class Meta: unique_together = ('identifier', 'container_id') After running the migrations, I've successfully created two MyItems with the same container and identifier='ab' and 'Ab' -

Google App Engine deployment error 502: Bad Gateway with Django and Gunicorn
I am trying to deploy a Django application on Google App Engine using Gunicorn as the WSGI server.

Local gulp not found inside docker container

Django forms's logic for a form in a base template
I'm trying to figure out how to deal with this situation. I have three views: def view0(request): ... return render(request, 'home.html') def view1(request): ... return render(request, 'about.html') Both view templates extends a template called 'base.html', in which there is a contact form. What I'm wondering is: do I need to write python code in both views to handle all the logic inherent in the form's operation? Or can I create a view whose only job is to handle the logic of this specific form? I tried to create a separate view, assigning it a url to which the 'action' attribute of the form refers: def base_view(request): if request.method == 'POST' contact_form = Form(request.POST) #logic here else: contact_form = Form() context = {'contact_form': contact_form} return render (request, 'base.html', context) def view0(request): ... return render(request, 'home.html') def view1(request): ... return render(request, 'about.html') 'base.html' has the following code for the form: ..... <form action="{% url 'base_view_url' %}" method="post"> {% csrf_token %} {{contact_form}} <input type="submit" value="Invia"> </form> .....

Database Optimization of a Giveaway Website Using Django
Hello everything is fine? So, the old project that is a "raffle" site has a chronic problem which is the use of up to 1000% of the CPU that is an AMD Ryzen 9 with 16 cores at high peaks of site usage. The total responsible for this enormous use is the database due to its lack of architecture/optimization. The challenge is: Solve this and make the site fast and accessible. For that, I'll use Django and thought of some ways to solve this, among them, here's a possible solution. models.py from the app raffle class Raffle(models.Model): ... amount_of_numbers = models,PositiveInteger(default=100000) The system will define the total number of tickets or the user and with these numbers, in the save method I will create 50-100 .txt files with numbers from 1 to 100000 without repetitions to avoid adding repeated numbers and causing " harmful queries" import fcntl with open('arquivo.txt', 'r') as arquivo: fcntl.flock(arquivo, fcntl.LOCK_EX) ... fcntl.flock(arquivo, fcntl.LOCK_UN) I will use the a lib fcntl to guarantee that only one user has access to that list of numbers (that's why several lists) and avoid having to check repeated numbers in the database and after finishing the process, I will release the … -

Problems with Django structuring when entering models, views and serializers in folders?

I was told that inside each folder create the init.py and integrate there the from of what is created in that folder, but when I start to spread it to the other modules it generates error.

Does apply_async(retry=False) disable the task level retry
I have a task like such @shared_task(bind=True, max_retries=150) def payout_reconciliation_single_task(self, txn_id): try: txn = Transaction.objects.filter(pk=txn_id).select_for_update().get() except Transaction.DoesNotExist: self.retry(throw=False, countdown=10 * 60) return Now if I call the task like payout_reconciliation_single_task.apply_async((123,), countdown=10, retry=False) Will the self.retry inside the try-catch block inside the except block in the task still be honored?
