JavaScript "Uncaught DOMException: Failed to execute 'insertBefore' on 'Node'
can anyone help me with this message error, please? "Uncaught DOMException: Failed to execute 'insertBefore' on 'Node': The node before which the new node is to be inserted is not a child of this node. at HTMLButtonElement." I don't know javascript, but I need this code in my Django(a python framework) app to create a dynamic form. I pick up this code in this tutorial https://engineertodeveloper.com/dynamic-formsets-with-django/ . My template is almost identical to tutorial's template. The difference between then is that my formset have three fields to fill and the tutorial's formset(not the main form) has one field. JavaScript code by https://engineertodeveloper.com/dynamic-formsets-with-django/ : const imageForm = document.getElementsByClassName("image-form"); const mainForm = document.querySelector("#pet_form"); const addImageFormBtn = document.querySelector("#add-image-form"); const submitFormBtn = document.querySelector('[type="submit"]'); const totalForms = document.querySelector("#id_form-TOTAL_FORMS"); let formCount = imageForm.length - 1; function updateForms() { let count = 0; for (let form of imageForm) { const formRegex = RegExp(`form-(\\d){1}-`, 'g'); form.innerHTML = form.innerHTML.replace(formRegex, `form-${count++}-`) } } addImageFormBtn.addEventListener("click", function (event) { event.preventDefault(); const newImageForm = imageForm[0].cloneNode(true); const formRegex = RegExp(`form-(\\d){1}-`, 'g'); formCount++; newImageForm.innerHTML = newImageForm.innerHTML.replace(formRegex, `form-${formCount}-`); mainForm.insertBefore(newImageForm, submitFormBtn); totalForms.setAttribute('value', `${formCount + 1}`); }); mainForm.addEventListener("click", function (event) { if (event.target.classList.contains("delete-image-form")) { event.preventDefault(); event.target.parentElement.remove(); formCount--; updateForms(); totalForms.setAttribute('value', `${formCount + 1}`); } }); My Django template: <div … -
Why does Django auto_now_add fail with not null on insert or update
I am trying to implement a data warehouse. So the django system will query an api at regular intervals to update the database. I am using client ids as the primary key which might be the problem but when I do save I obviously want it to create or update. I get this error whatever I do! django.db.utils.IntegrityError: null value in column "created" violates not-null constraint So originally I just had my model like this: class PersonalTaxClient(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) invoice_client = models.ForeignKey(InvoiceClient, blank=True, null=True, on_delete=models.PROTECT) client_name = models.CharField(max_length=100) email = models.CharField(max_length=100) Then I tried: class PersonalTaxClient(models.Model): created = models.DateTimeField(editable=False) updated = models.DateTimeField() client_code = models.CharField(max_length=20, primary_key=True) invoice_client = models.ForeignKey(InvoiceClient, blank=True, null=True, on_delete=models.PROTECT) client_name = models.CharField(max_length=100) email = models.CharField(max_length=100) # history = HistoricalRecords() def save(self, *args, **kwargs): ''' On save, update timestamps ''' print(timezone.now()) if not self.client_code: self.created = timezone.now() self.modified = timezone.now() return super(PersonalTaxClient, self).save(*args, **kwargs) and try to update like this: >>> from sbsite.models import PersonalTaxClient >>> p = PersonalTaxClient(client_code="HHH001", client_name="Bob") >>> p.save() I get the same error. I've read about 20 other SO pages but am none the wiser..............! -
Django child models don't inherit Meta inner class
I have two Django 3.0 models, one of which is a subclass of the other: # models.py class BaseCategory(models.Model): class Meta: verbose_name_plural = "categories" class Category(BaseCategory): # fields 'n' stuff Only the Category model is registered in the Admin # admin.py @admin.register(Category) class CategoryAdmin(admin.ModelAdmin): # stuff here In the Admin, the Category model is labeled "Categorys", despite the fact that it should have inherited the Meta inner class and its verbose_name_plural attribute from BaseCategory. In fact, if I copy the same code into the Category model, # models.py class Category(BaseCategory): class Meta: verbose_name_plural = "categories" # fields 'n' stuff the model is correctly labeled "Categories" in the Admin. This indicates that the Category class is not inheriting the Meta inner class of BaseCategory. Why does a child class not inherit the Meta inner class? Is there another way for me to only specify verbose_name_plural once instead of copying the exact same code into every child of BaseCategory? -
django-mssql-backend - Invalid connection string attribute (0)
OK, I'm slowly going crazy. I want to connect Django 3 to MSSQLv15 Server. Connection works if I use Trustedconnection=yes (using win credentials), it also works on Ubuntu if I'm using FreeTDS v7.4 but it won't work in Windows if I want to use service account or personal credentials without Trustedconnection.

when exactly django query execution occures
In a technical interview a questioner asked me a weird question regarding to the execution of querysets. Suppose we have a profile model like below: class Profile(models.Model): user = models.OneToOneField('User').select_related(User) surname = models.TextField(null=True) q = Profile.object.all() or q = Profile.object.get(id=1) l = q.filter(active=True) he asked how many query execution has been happened and I replied as the python interpreter executes Profile.object.all() at the begging then one query is already done. However, he answered zero, and one if we call the query, something like this: for a in l: a.surname Is his answer true in django? another doubt was about models.OneToOneField('User'), why he didn't use django.contrib.auth.models.User and defined models.OneToOneField('User').select_related(User) -

How can I put 2 views in one template? Django
To put multiple forms in one view we are using request.POST.get(name argument of form), but When I am doing that with my register and login page than the login page is working, but I cant see the register form. The problem is to check if request is POST and than return the result for each case. def index(request): # login view if request.user.is_authenticated: return render(request, 'authenticated.html') else: if request.method == 'POST': username = request.POST['username'] password = request.POST['password'] user = auth.authenticate(username=username, password=password) if user is not None: auth.login(request, user) return redirect('index') else: messages.error(request, 'Username or password is incorrect, try again!') return render(request, 'index.html') def register(request): if request.method == 'POST': form = UserRegisterForm(request.POST or None) if form.is_valid(): form.clean_email() form.save() username = form.cleaned_data.get('username') messages.success(request, f'Successfully created account for {username}') return redirect('index') else: form = UserRegisterForm() return render(request, 'users/register.html', {'form': form}) Html for login and registration <form method="post" name="login"> {% csrf_token %} <input type="text" name="username" placeholder="username"> <input type="password" name="password" placeholder="password"> <input type="submit" value="Login Yeah!"> </form> <form method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Sign Up"> </form> -

How to redirect to an authenticated view with access token from another app in Django?
I have a Django website with two apps running on it. On app 1 the user receives an auth token and is supposed to be redirected to app 2 with said token. App 2 requires authentication in all views through APIView's permission_class "IsAuthenticated". app2/urls.py: app_name = 'app2' urlpatterns = [ path('',views.waitingroom_view.as_view(), name = 'waitingroom_index'), path('authenticated/',views.authentication_view.as_view(), name ='authentication') ] app2/views.py: class waitingroom_view(APIView): def get(self, request): return redirect('app1/index') My code correctly authenticates the user by giving them authentication tokens (refresh and access tokens) through a requests.post function: app1/views.py: def get_authentication_tokens(request, username, password): #BEWARE: hardcoded URL url = 'http://127.0.0.1:8000/api/token/' postdata = { 'username': username, 'password': password, } r = requests.post(url, data=postdata) tokens_json = r.json() #splits the respective tokens into 2 variables: "refresh" and "access" refresh_token = tokens_json['refresh'] access_token = tokens_json['access'] return access_token, refresh_token response = requests.get('http://0.0.0.0:8000/authenticated', auth=BearerAuth(access_token)) return HttpResponse(response) This returns a .html page that requires an auth token to access. However, the return is on app 1 instead of redirecting to app 2 with auth token. How do I redirect to an authenticated view (app 2) from another app (app 1) (that generated the auth token)? -

What is the best video storage solution
I have an application which connects to Instagram API and pulls massive amount of data everyday. My next challenge is to pull and save many Instagram users stories to a storage, then let my application users to see/view those stories in my django web app. I need to save nearly 50 GB of short videos (stories) everyday This makes nearly 20 TB of data for a year, so the storage must be at least that big The amount of stories that will be watched per day on my web app will be < 1000 (less than 1 GB) I don't have any experienced developers/engineers around me, so I do my own research about the subject. Azure Blog Storage looks like the solution that fit my needs but also a very expensive one (200-400$ per month). I have experience with Postgres and MySQL databases but not with Cloud services like Google or Azure, so any links, advices and tips are appreciated highly. -

Django model query .values() on a JSONfield
I have a JSONfield that contains a lot of data that I need to aggregate over, but i'm having a little trouble doing so. So I have a field in the JSON data that contains the amount of cores for a specific node, and i'd like to grab all these values in the DB and count them afterwards. I've tried the following data = Node.objects.filter(online=True).values( data__golem.inf.cpu.cores).annotate(the_count=Count(data__golem.inf.cpu.cores)) But that didn't work out, which might be because JSONfield doesn't support .values() queries? I'm not sure if that's the case anymore but it was mentioned at an old answer back from 2017. Next thing I tried was to just filter the by online=True and loop over each element in the QuerySet and then get the golem.inf.cpu.cores manually and add that to a dict and add it all together in the end. But that results in a KeyError and that's because of the punctations in the fieldname I would assume? How can I go on about this? print(obj.data['golem.inf.cpu.capabilities']) KeyError: 'golem.inf.cpu.capabilities' views.py @api_view(['GET', ]) def general_stats(request): """ List network stats.

Django - Limiting selection of many to many field on ModelForm to just values from parent record
Could really use some help. I have a django app that has the following tables: Mission. Package. Target. Flight. A mission has 1 or many packages. 1 or many targets and 1 or many packages. A package has one or many flights. A Flight has a many to many relationship such that there is a multi-select field that allows you to select pre-added targets (added as children of the mission parent) to the flight. The problem is the dropdown shows all targets ever added to the database. I was expecting it would only show targets that belong to the mission parent. How do I limit the target options that appear in the Flight form, to just those of targets that belong to a mission?

Django annotate and apply different aggregation functions on the same field

To recap: How I could apply multiple aggregation functions on the same field using annotate? -
Make HTML custom field sortable in django-admin
I have a very simple model that just consists of a name and serial number. I can use that serial number to ask for a status on an API and I want to display the result as icon/HTML: class ProductAdminForm(admin.ModelAdmin): class Meta: model = Product fields = ["get_status", "name",] def get_status(self, obj): status = get_status_from_API(obj)["status"] style = """style="height: 10px; width: 10px; border-radius: 50%; COLOR display: inline-block;" """ if status == 2: new_style = style.replace("COLOR", "background-color: green;") elif status == 2: new_style = style.replace("COLOR", "background-color: red;") else: new_style = style.replace("COLOR", "background-color: grey;") return mark_safe(f"""<span class="dot" {new_style}></span>""") How can I make the get_status column sortable? -
