django inlineformset_factory not saving the froms data
Why the data of inlineformset_factory not saving? here is my code: models.py class HeaderImage(models.Model): header_image = models.ImageField() post = models.ForeignKey(Post, on_delete=models.CASCADE) froms.py BlogImageFormSet = inlineformset_factory(Post, # parent form HeaderImage, # inline-form fields=['header_image'] ,can_delete=False, extra=1) #views.py class BlogUpdateView(PermissionRequiredMixin,UpdateView): raise_exception = True permission_required = "blog.change_post" model = Post template_name = "blog_update_post.html" form_class = BlogPost def get_success_url(self): self.success_url = reverse_lazy('my-account') return self.success_url def get_context_data(self, **kwargs): context = super(BlogUpdateView, self).get_context_data(**kwargs) if self.request.POST: context['form_image'] = BlogImageFormSet(self.request.POST, instance=self.object) else: context['form_image'] = BlogImageFormSet(instance=self.object) return context def form_valid(self, form): context = self.get_context_data() image_form = context['form_image'] if image_form.is_valid(): self.object = form.save() image_form.instance = self.object image_form.save() return HttpResponseRedirect(self.get_success_url()) else: return self.render_to_response(self.get_context_data(form=form)) I am not understanding why data is not saving for inlineformset_factory field. -
Django JSONfield update element in list
I'm using a JSONField to store a list of elements in this format: [{"name": "field1", "value": "100"}, {"name": "field2", "value": "500"}] This is my model: from django.contrib.postgres.fields import JSONField class MyModel(models.Model): json_data = JSONField(default=list, null=True) # Create an empty list always I have a form to update the values stored in json_data, I update the data like this: obj = MyModel.objects.get(pk=1) json = obj.json_data # [{"name": "field1", "value": "100"}, {"name": "field2", "value": "500"}] new_data = {"name": "field2", "value": "99"} # data to update that comes from form fields_not_updated = [field for field in json if new_data['name'] != field['name']] # Create a list of elements that are not updated fields_not_updated.append(new_data) # Add the new data, output: [{"name": "field1", "value": "100"}, {"name": "field2", "value": "99"}] obj.json_data = fields_not_updated # set new json obj.save() # save object I was wondering if there is an easier or more efficient method to update the elements inside the list and save them in the JSONField using django functions or methods or directly using python. -

Django creates two model instances instead of one
I'm trying to learn some django basics and have got strange result when I try to create some model instances using forms. This is my view: from django.shortcuts import render from .forms import ProductModelForm from .models import Product def create(request): form = ProductModelForm(request.POST or None) if form.is_valid(): obj = form.save(commit=False) data = form.cleaned_data Product.objects.create(title_text=data.get("title_text")) obj.save() return render(request, "test_app/create.html", {"form": form}) Form: from django import forms from .models import Product class ProductModelForm(forms.ModelForm): class Meta: model = Product fields = [ "title_text", ] And a template: {% block content %} <form action="." method="post">{% csrf_token %} {{ form }} <button type="submit">Save Model</button> </form> {% endblock %} Thanks in advance. -

Using Django to create Strava Webhook subscription
I am trying to create a Strava webhook subscription to recieve events from users who have authorised my Strava application. I was able to successfully create a subscription using the code in this Strava tutorial. However, I don't understand Javascript, so can't adapt the code to my needs. I am therefore trying to replicate it's functionality within Python using Django. My basic approach has been to follow the setup outlined in the Django section of this webpage, then replace the code in the file views.py with the code below. I have tried to make the code function as similarly as possible to the Javascript function within the tutorial I linked above. However, I'm very new to web applications, so have taken shortcuts / 'gone with what works without understang why' in several places. from django.http import HttpResponse from django.views.decorators.csrf import csrf_exempt from django.views.decorators.clickjacking import xframe_options_exempt import json @csrf_exempt @xframe_options_exempt def example(request): if request.method == "GET": verify_token = "STRAVA" str_request = str(request) try: mode = str_request[str_request.find("hub.mode=") + 9 : len(str_request) - 2] token = str_request[str_request.find("hub.verify_token=") + 17 : str_request.find("&hub.challenge")] challenge = str_request[str_request.find("hub.challenge=") + 14 : str_request.find("&hub.mode")] except: return HttpResponse('Could not verify.

Autocomplete for input with Django, Bootstrap and JQuery
I have a form in Django + Bootstrap/JQuery, and the fields (labels/inputs) are generated from a ModelForm, that is, directly from Django and not in the .html, just like this: <div class = "panel" id = "personal_data"> <div class = "panel-body"> {% bootstrap_form client_form%} </div> </div> This "client_form" is a .py, which contains a ModelForm, which contains the fields automatically generated when the page is loaded My goal is to make an autocomplete on a specific input of this form, for example "Client Name". This autocomplete would show names the same as those typed by the user in real time, and each name would have a link to redirect to another page, it could be, for example, a page to change that customer's data The autocomplete data must come from a function that queries the database! Consider that this function already exists I tried to do this with Typeahead and Bloodhound but I couldn't -

Django - catch migrating process

How can I add a relationship in Django to a model that's created before the model I need to reference?
I have two different models: Movies and Characters. I want Characters to have a movies field where I can see the movies in which the characters appear and I want Movies to have the characters that appear in them. However, since one of the models has to be defined first, I am not sure how to make the first one relate to the second one. This is my code so far but this doesn't show 'movies' when I access the Character model: class Character(models.Model): image = models.ImageField() name = models.CharField(max_length=100) age = models.IntegerField() story = models.CharField(max_length=500) def __str__(self): return self.name class Movie(models.Model): image = models.ImageField() title = models.CharField(max_length=100) creation_date = models.DateField(auto_now=True) rating = models.IntegerField() characters = models.ManyToManyField(Character) def __str__(self): return self.title I am not sure how to add the movies to the Character model since it's referenced before the Movie model, how can I accomplish this? Thank you. -

Django Class based views and their cohesion
I'm coming from laravel and trying to do something like laravael model controller where functions are mapped to request methods and no of arguments. I tried to find something similar in Django but the class based views are too scattered. The conventional approach with CBVs(ListView,TemplateView,GenericEditView) won't let me implement all the function in one class. That would make a number of classes and a number of URLs to handle also, so with my low knowledge, I have done the thing below. Please check and guide. class InvoiceView(View): @method_decorator(login_required) def dispatch(self, request, *args, **kwargs): if (args or kwargs) and request.method == 'GET': if kwargs['data'] =='create': return self.create(request,*args,**kwargs) else: return self.show(request, *args, **kwargs) else: return super().dispatch(request, *args, **kwargs) def get(self,request): all_invoice = Invoice.objects.all() content = {'invoices': all_invoice} return render(request, 'Invoicing/invoice/index.html', context=content) @transaction.atomic def post(self, request): data = json.loads(request.POST.get('data')) inv = Invoice(payment_mode=data['invoice_details']['payment_mode'], total_amount=float( data['invoice_details']['total_amount']), created_by=User.objects.get(pk=1)) inv.customer = Customer.objects.get( pk=data['invoice_details']['customer_id']) inv.full_clean(exclude='id') inv.save() inv_data = data.pop('invoice_details') for key in data: if key in ('sublimation', 'printing'): self.addOrder(inv, data[key], key) elif key in ('designing', 'transfer', 'ink', 'paper', 'part'): self.addItems(inv, data[key][0], key) message = 'Stored successfuly' if inv_data['payment_mode'] == '0': inv.payment_status = 0 inv.save() pmnt = Payment(invoice=inv, amount=inv.total_amount, payment_method=2) pmnt.save() return HttpResponse(json.dumps({ 'message': message, 'link': reverse('invoice'), 'template': render_to_string('Invoicing/invoice/printPreview.html',context=self.extract_invoice_data(inv.id)) … -
Django loading image from url - ImageField objected has no attribute _committed
I am using Django 3.2 I am trying to programatically create a model Foo that contains an ImageField object, when passed an image URL. This is my code: image_content = ContentFile(requests.get(photo_url).content) # NOQA image = ImageField() # empty image data_dict = { 'image': image, 'date_taken': payload['date_taken'], 'title': payload['title'], 'caption': payload['caption'], 'date_added': payload['date_added'], 'is_public': False } foo = Foo.objects.create(**data_dict) # <- Barfs here foo.image.save(str(uuid4()), image_content) foo.save() # <- not sure if this save is necessary ... When the code snippet above is run, I get the following error: ImageField object does attribute _committed I know this question has been asked several times already - however, none of the accepted answers (from which my code is based) - actually works. I'm not sure if this is because the answers are old. My question therefore is this - how do I fix this error, so that I can load an image from a URL and dynamically create an object that has an ImageField - using the fetched image? -
Add columns in django model table postgres
I recently edited my table and had overriden the primary_key to a title attribute. I tried deleting all previous migrations and even so, the model id, which should be the pk by default, isn't so. Since then I've been trying to add a new column id to my appname_model table. Here the appname is courses and model-class is course (written in lowercase in reference to the tablename statement I just made) I've entered the following commands multiple times and none have managed to add the field id: ALTER TABLE courses_course ADD COLUMN id int constraint; I've tried several other variants of the same syntax from other stackoverflow questions but none have worked out so far. I also want to set id to the primary key in that table. -

Cannot assign "'1'": "Offers.state must be a "States" instance
I have read several answers to this same question, but none have worked for me.

And as you can see, i am passing an instance, not the id of the element. I use the id that comes from the form just to query the DB and find the instance with this: state = States.objects.get(pk=request.POST['state']) The form works just fine, and I tried to do it with forms.py and if form.is_valid(), but got the exact same result. am on: django 3.2.3 python 3.9.2 -
Django automatically appending csrftoken to cookies send by React Native request
I've got a React Native app that is making requests using axios to my django server. const axios = require("axios").create({ baseURL: BASE_URL, headers: { 'cookie': `credentials=abc123;`, 'X-Requested-With': 'my_custom_app', } }); On my Django app, I am printing out the cookies for the request. print(request.COOKIES) When I'm printing the cookies on my local instance of the backend, things look fine: Here's the output from my local instance: {'credentials': 'abc123'} But on my prod instance of the server, the output is different: {'csrftoken': 'B17DuZmxWPyuTAEdcldsJqZX0dsDct4k6nHLXYtRPiJQFEpBrSPIH5G7M6rty0FH,credentials=abc123'} This obviously gets read incorrectly by the server and it thinks that my credentials are not available in the cookie. I'm not sure what is going on here, or why this only happens on my production instance. -
Optimal way for letting user download big files in the server using Django
I am making a Django application for an experiment and it will offer the possibility to the user to be able to download really big image files to a specific directory in the server. I have a PoC of that working, where the user sees a button clicks on it and the process to download begins. I have put the download process inside views.py which means it occurs upon visiting a specified URL. The code responsible for the download part similar to the following: with open(loc, "wb") as f: response = s.get(pos, stream=True) total_length = response.headers.get('content-length') if total_length is None: f.write(response.content) else: dl = 0 total_length = int(total_length) for data in response.iter_content(chunk_size=4096): dl += len(data) f.write(data) The problem is that for some images which are > 500MB the process takes quite some time and there are several issues, like if the user closes the app, or clicks away then the process stops. How can I make it in such a way so the user visits that page and clicks that button and the download process begins on the background without binding the user to stay to that page. Also maybe creating another endpoint which could update the user about the … -
