Django ModelFormSet to answer an ordered list of questions that shouldn't change their order in the formset after submit if answered in a random order
I have to display a Django formset containing a list of predefined questions (a few dozen questions) arranged in a specific order. The user has the freedom to answer whatever questions they want, in an arbitrary order, save their answers, and continue answering later. So there are no mandatory fields. For instance the user answers the questions 2, 5, 6, and 7: Question Answer Question 1 Question 2 Answer to question 2 Question 3 Question 4 Question 5 Answer to question 5 Question 6 Answer to question 6 Question 7 Answer to question 7 Then the user submits the formset. The first issue I had was that after submitting the formset the newly added answers (and their questions) were moved to the top of the formset: Question Answer Question 2 Answer to question 2 Question 5 Answer to question 5 Question 6 Answer to question 6 Question 7 Answer to question 7 Question 5 Question 6 Question 7 The (simplified) models I used are: class Question(models.Model): position_nr = models.SmallIntegerField(db_index=True) content = models.CharField(max_length=200) class Answer(models.Model): question = models.ForeignKey(Question, on_delete=models.PROTECT) content = models.CharField(max_length=100, blank=True, null=True, ) I used a ModelFormSet. In the simplified versions of my view and forms (see below) the … -
django - submit multiple forms in one post request (different from one click cause I need to process the data of those two forms together!)
I have two models jobposition and wage and models are related by a OneToMany relation. class JobPosition(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) title = models.ForeignKey(Title, on_delete=models.CASCADE) ... class Wage(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) amount = models.FloatField(blank=True,null=True) type = models.CharField(choices=WAGETYPE, max_length=30) position = models.ForeignKey(JobPosition, related_name='wages', on_delete=models.CASCADE, blank=True, null=True) I am building a user interface where a user can create a position with associated wage (let's say just one wage for now). The problem I am facing is that I would like to do this using some combination of forms instead doing everything manually. I created these two forms and served them to a django template using a templateview class JobPositionForm(forms.ModelForm): class Meta: model = JobPosition fields = ['title','city','dept_head','files','department_budget'] ... class WageForm(forms.ModelForm): class Meta: model = Wage exclude = ['id'] The page is rendered smoothly, however I am now realizing that I don't know how to submit those two forms together inside a single post request. I thought about using formset but I don't know how to use it with different forms. I guess I can always do this manually using Javascript to parse each value and place it into the same POST... but I was hoping there was a work … -

Odd Django queryset behavior trying to filter use 'lte' filer on datetime field
I'm seeing some weird behavior with one of my models and am having a hard time tracing down what's going on.

jsonfield queryset and filtering

CSRF token missing or incorrect - using auto-complete light in Django
Running into CSRF_Token missing or incorrect in my Django-app, don't really understand what the issue is as I've included the {% csrf_token %} in any possible form being rendered by my template. I suspect it may have to do with the ajax requests that are done within the form to retrieve area-names and more, maybe someone can tell me what the issue is.

Django Countries - unable to pre-select the right country in an edit form
Consider this model: class Address(models.Model): line1 = models.CharField(max_length=255, db_index=True, blank=True, null=True) city = models.CharField(max_length=255, db_index=True, blank=True, null=True) state = models.CharField(max_length=255, db_index=True, blank=True, null=True) postcode = UppercaseCharField(max_length=64, blank=True, db_index=True, null=True) country = CountryField(db_index=True, blank=True, null=True) I'm trying to populate this model using data that comes in through webhook call. I'm having trouble populating the country in two cases: When the country is "United States" (this is what the webhook returns, I have no control over it) - django_countries does not recognize this, so I added an if condition to change "United States" to USA before creating a new Address object but, when the country is not United States, for example "Panama", I populate it directly into the model by doing this: country = request.POST.get('country') # returns something like "Panama" Address.objects.create(line1=line1, city=city, state=state, country=country) This works fine, except when I try to edit the Address form, the country field is blank, it isn't pre-selecting "Panama" from the options. I know the country field of this Address instance is a country object because I can do address_form.instance.country and it outputs Pa, if I do address_form.instance.country.name it outputs Panama. So why isn't the country field in the form pre-selecting the right Country, why does … -
Azure Hosted ASGI Django Server Bottleneck When Handling Over a Dozen Simultaneous Requests
I'm new to working with ASGI and I'm having some performance issues with my Django API server so any insight would be greatly appreciated. After running some load tests using JMeter it seems that the application is able to handle under 10 or so simultaneous requests as expected, but any more than that and the application's threads seem to lock up and the response rate vastly diminishes (can be seen in sample #14 and up on the 'Sample Time(ms)' column in the screenshot provided). It's as if requests are only being processed on 1-2 threads after that point as opposed to the configured 4. Here is my startup.sh config: gunicorn --workers 8 --threads 4 --timeout 60 --access-logfile \ '-' --error-logfile '-' --bind=0.0.0.0:8000 -k uvicorn.workers.UvicornWorker \ --chdir=/home/site/wwwroot GSE_Backend.asgi I am aware that the individual API responses are quite slow. That is something I want to address. However, is there perhaps something I am doing wrong on the ASGI level here? Thanks. -
