Error with PgBouncer on Heroku with Django and Docker
I'm currently running into database connection issues with my Django & Postgres app hosted on Heroku. Before upgrading my database plan, I wanted to try solving the issue with pgbouncer. According to this article by Heroku, the Procfile would need to be updated from something like web: gunicorn hellodjango.wsgi to web: bin/start-pgbouncer-stunnel gunicorn hellodjango.wsgi after provisioning the pgbouncer buildpack. The thing is, I don't use a Procfile but a heroku.yml. Currently, my yml file has this: run: web: command: - gunicorn --bind 0.0.0.0:$PORT --workers 1 --threads 8 --timeout 0 my_app.asgi:application -k uvicorn.workers.UvicornWorker I tried updating the web command to this: bin/start-pgbouncer-stunnel gunicorn --bind 0.0.0.0:$PORT --workers 1 --threads 8 --timeout 0 my_app.asgi:application -k uvicorn.workers.UvicornWorker but that gives me this error: bin/start-pgbouncer-stunnel: not found I tried this answer as well, but get an pgbouncer: unrecognized service error. Any ideas on how to solve this? -

Django test suite throws error on field that's not loaded: "could not convert string to float"
The following simple test throws the errors ValueError: could not convert string to float: '' The above exception was the direct cause of the following exception: ValueError: Field 'amount' expected a number but got ''. from django.test import TestCase from .models import Customer class TestSetup(TestCase): def setUp(self): self.testCustomer = Customer(firstname='Ron', street_name='Somestreet', street_suffix='Dr', street_number='1', phone='111-111-1111', city='Somecity', zipcode='87000') The field 'amount' does exist, but in a model that isn't loaded for any tests: class Appointment(models.Model): amount = models.FloatField(blank=True, default=0.0) But just in case it's instantiating that model in the process of creating the test database, I migrated "default=0.0" to "default='0.0' " (Single quotes around the value). Same error. I'm initiating the test with python manage.py test from the project directory. -

Django's update_or_create failing although kwargs is specified
I have the following Django model: class Itens(models.Model): id = models.AutoField(primary_key=True) itempr_id = models.IntegerField(unique=True) # This is NOT a relationship cod_item = models.CharField(max_length=16, unique=True) # Other fields... As you can see, both itempr_id and cod_item are unique, so I specified update_and_create to take this into account: class CreateItensSerializer(serializers.ModelSerializer): class Meta: model = Itens fields = '__all__' def create(self, validated_data): item, created = Itens.objects.update_or_create( itempr_id=validated_data.get('itempr_id'), cod_item=validated_data.get('cod_item'), defaults=validated_data ) return item I call and save the serializer like this: serializer = CreateItensSerializer(data=itens, many=True) if serializer.is_valid(): serializer.save() However, whenever there is a duplicate, I get the following error: {'itempr_id': [ErrorDetail(string='itens with this itempr id already exists.', code='unique')], 'cod_item': [ErrorDetail(string='itens with this cod item already exists.', code='unique')]} I do not expect any uniqueness violation problems since the fields were already specified to be unique in the function call How can I fix this? EDIT: just to make it clear, this works if the DB's table is empty, there's no problem in the itens argument in serializer = CreateItensSerializer(data=itens, many=True) -
How to access Django session using class-based views? (with Angular) The self.request.session.get('key') returning None
I am currently developing a Django/Angular application. Within the frontend component, several methods are called upon initialization (ngOnInit), and these methods all rely on the same base query (and then they do other things with that data). What i'm trying to do is to create a single method that retrieves the base data used by these other methods. What I'm currently doing here is to query this base data once, store it in the Django session and then access it from the other views as needed (I would appreciate any alternative points of view if you think this aint a good solution). The issue is that I can't access the Django session beyond the view where is being created. Whenever I try to access it from the other views I get 'None'. Here is a simplified version of my Angular code: export class AnalysisComponent { fieldID = 4; constructor(private _service: Service) {} async ngOnInit() { await this.getBaseData(this.fieldID); // I used async/await so the other methods do not execute until this one is over. this.testOne(this.fieldID); this.testTwo(this.fieldID); this.testThree(this.fieldID); } async getBaseData(field_id){ try { const result = await this._service.getBaseData(field_id).toPromise(); } catch (error) { console.error(error); } } testOne(field_id) { this._service.testOneView(field_id).subscribe( (data: any) => { … -

How to pass request object for dynamic form in django-formtools form wizzard?
Probably there is someone who's tried to make multistep form wizzard, but the goal is to make them dynamic. By dynamic i mean that after submiting one form, this form remains in its position and data from this form is sent in ajax and if it's valid a server sent html with second form. Seems to be easy, but i'm really strugling how to render csrf_token in dynamic forms. So, i have main.html like: <div class="col-xxl-6" id="testId"> {{ wizard.form }} </div> and partial htmls with forms, like first_form.html: {% load static %} <form action="{% url 'app:url' %}" method="post" novalidate> {% csrf_token %} {{ wizard.management_form }} {{ first_form.field }} </form> and the second_form.html is the same, let's say so, obviously, i have to pass a request and it's completely possible to do that with render_to_string if form is supposed to be sent with AJAX. But in case with regular rendering (without AJAX) render_to_string is not the appropriate way. Another best place i find: __init__ in my form i looked at the render() method in class RenderableMixin, which is parent for forms.Form and wanted to do something like this: class MyForm: template_name = "app/templates/forms/first_form.html" def __init__(self, request=None, *args, **kwargs): self.request = request … -
How to upload files with Django and Python

Autocomplete dropdown for related-field filtering in Django admin
I'd like to have a nice autocomplete dropdown in my Django admin backend for filtering out results in the project model according to the subject attached to a person. this is my models.py: class Person(models.Model): subject = models.ForeignKey(Subject, on_delete=models.CASCADE, blank=True, null=True) class PersonRole(models.Model): project = models.ForeignKey('Project', on_delete=models.CASCADE) class Project(models.Model): person = models.ManyToManyField(Person, through=PersonRole) For now I managed to get a simple list using SimpleListFilter with the following code in admin.py: class PISubjectFilter(admin.SimpleListFilter): title = 'PI Subject' parameter_name = 'subject' def lookups(self, request, model_admin): return Subject.objects.values_list("id", "name").order_by("id") def queryset(self, request, queryset): count = range(1, 100) for x in count: if self.value() == str(x): return queryset.filter( person__personrole__person__subject=x ).distinct() break How can I turn this long list into a autocomplete dropdown?

I am new to django and am not able to implement it properly. form.py class Files_uploadedForm(forms.Form) doc_name=forms.CharField(max_length=100) doc_type=forms.CharField(max_length=5) description=forms.CharField(max_length=100) remarks=forms.CharField(max_length=100) Files_uploadedFormSet=formset_factory(Files_uploadedForm) view.py if request.method='POST' med_qrset=medical_doc.objects.values('doc_name','doc_type','description','remarks') .filter(doc_id=doc_id) formset=Files_uploadedFormSet(queryset=med_qrset) context = {'formset'=formset} return render(request,"upload_doc.html") upload_doc.html ... {% for form in formset %} form.as_p {% endfor %} Please excuse the syntax errors.My issue here is to know it this method of initialising formset is correct. Because I get a error saying that BaseFormSet.init() got an unexpected keyword argument 'queryset'. Please help. -
Django post request is good in postman but not from frontend with the same payload
Django api interface and postman is working fine in posting the payload, however with the exact same payload posted from my frontend it doesn't work even while disabling cors. -This is my mode: `class Activity(models.Model): cid = models.CharField(max_length=10) percent = models.IntegerField() name = models.CharField(max_length=255)` -this is my view: class ActivityViewSet(viewsets.ModelViewSet): queryset = Activity.objects.all() serializer_class = ActivitySerializer def get_queryset(self): queryset = self.queryset # Start with the base queryset # Get the cid from the query parameters cid = self.request.query_params.get('cid') # If cid is provided in the query parameters, filter the queryset if cid: queryset = queryset.filter(cid=cid) return queryset -this is my url: `router.register(r'activities', ActivityViewSet)` And this is my frontend code: \` const postOutcomesAsync = async () =\> { function getCSRFToken() { const csrfCookie = document.cookie.match(/csrftoken=(\[\\w-\]+)/); if (csrfCookie) { return csrfCookie\[1\]; } return null; } const csrfToken = getCSRFToken(); axios.post('http://127.0.0.1:8000/activities/', inputValues[2], { headers: { 'Content-Type': 'application/json', 'X-CSRFToken': csrfToken } }); console.log('All activities posted successfully'); } \` The backend log shows OPTIONS 200 ok and no posting at all. Network tab shows post request failed but OPTIONS 200 ok. Axios shows network error 500. -
Vue 3 mutation is not reflected on Django backend
In my blog app, I want to like, dislikes and share posts using Vue 3 composition API. I provided Mutation class in schema.py and UpdatePostCounts Vue component. But for some odd reason the mutation is not showing on the Django backend database in Django Admin interface. How can I resolve this? Also how can I embed the likes, dislikes, and shares as I use SocialMedia.vue buttons?
