Is there a way to specify a "master" or "index" migration?
I'm working on an existing Django 2.2 application comprising a custom app in conjunction with a Wagtail CMS, where I'm iteratively adding new wagtail page-types in separate user stories over time. I want to be able to create a "master" or "index" migration that pre-builds each page-type in the database automatically when migrations are run (ours are performed in an Ansible task upon deployment). As far as I can tell, what I need requires: The auto-built migration that modifies the DB schema for each page A further migration that is always run last and which contains a dependencies attr - able to be updated with a single list-entry representing the new page's migration name, each time one is added. I can already auto-build page-types using the following logic in a create() method called from migrations.RunPython() but at the moment, this same page-build logic needs to exist in each page's migration - I'd prefer it if this existed in a single migration (or an alternative procedure if one exists in DJango) that can always be run. Ideally, the page_types list below could be replaced by just iterating over BasePage.__subclasses__(), (Where all page-types inherit from BasePage) meaning this "master" migration need never … -
How to make a read-only field in a Django formset
I've looked at a few other posts but they don't seem to work for me. I am trying to make one of my form fields to be read only but I can't get it to work. Here is my code. Also it isn't working perfectly when the form is posted, but it saves all the correct objects to the database. Gives the error 'list' object has no attribute 'dict' if you have any advice with that too. forms.py class OrderProductForm(forms.ModelForm): class Meta: model = OrderProduct fields = ('product', 'current_stock') def __init__(self, *args, **kwargs): super(OrderProductForm, self).__init__(*args, **kwargs) if self.instance.id: self.fields['product'].widget.attrs['readonly'] = True OrderProductFormSet = modelformset_factory(OrderProduct, extra=4, form=OrderProductForm) views.py class OrderProductCreateView(CreateView): model = OrderProduct form_class = OrderProductForm template_name = 'create_order_product.html' success_url = '/' def get_context_data(self, **kwargs): context = super(OrderProductCreateView, self).get_context_data(**kwargs) context['formset'] = OrderProductFormSet(queryset=OrderProduct.objects.none(), initial=[{'product': x} for x in Product.objects.all()]) return context def post(self, request, *args, **kwargs): formset = OrderProductFormSet(request.POST) if formset.is_valid(): return self.form_valid(formset) def form_valid(self, form): date = timezone.now() order = Order.objects.create(date=date) for item in form.cleaned_data: if item: order_product = OrderProduct(product=item.get('product'), current_stock=item.get('current_stock')) order_product.save() if order_product.order_amount() > 0: order.products.add(order_product) return super(OrderProductCreateView, self).form_valid(form) -
Django: Remove Exif data from Images in ImageField
There seem to be multiple variants of this question of how to strip exif data in django imagefields. None of the answers seem great. Many of them involve re-saving the image with PIL, at the risk of potentially breaking it. Others suggest using things like gexiv2... Given how important stripping exif is from image data for privacy is there any simple way to remove exif data from a user uploaded image? Perhaps this isn't even worth doing, since maybe it's less common of a precaution than I thought? -

ValueError at / dictionary update sequence element #0 has length 1; 2 is required
I have an issue i encounter while trying to run my urls & views in my Django project. It seems like that one way solves it but the other way (that suppose to work too, doesn't).

How to create class based views in Django with nested crud?
I was able to refactor half of my code to Class Based Views, but I am having a hard time with the nested crud portion of it. Here are my code. I am trying to refactor all the reviews to Class Views. I am new to this. Any advice would be helpful. Thank you. I have two models here. One is for Beer and the other is Review. A beer has many reviews so when I go to Beer_List, I am able to access all the reviews for that beer. I just don't know how to refactor the review into class based views. from .models import Beer, Review from .forms import BeerForm, ReviewForm from django.shortcuts import render, redirect def get_beer(beer_id): return Beer.objects.get(id=beer_id) def beer_list(request): beers = Beer.objects.all() return render (request, 'beers/beer_list.html', {'beers': beers}) def new_beer(request): if request.method=="POST": form = BeerForm(request.POST or None) if form.is_valid(): beer = form.save(commit=False) beer.save() return redirect('beer_detail', beer_id=beer.id) else: form = BeerForm() return render(request, 'beers/beer_form.html', {'form': form, "type_of_reqeust": "New"}) def beer_detail(request, beer_id): beer = get_beer(beer_id) return render (request, 'beers/beer_detail.html', {'beer': beer}) def edit_beer(request, beer_id): beer = get_beer(beer_id) form = BeerForm(request.POST or None, instance=beer) if form.is_valid(): form.save() return redirect('beer_list') return render(request, 'beers/beer_form.html', {'form': form, 'type_of_reqeust': 'Edit'}) def delete_beer(request, … -
Django Queryset get value

When testing Django REST Framework, why can't I get APIClient.credentials() to authenticate using a token?
I'm writing a functional (not unit) test against a basic API, like so: from decouple import config from rest_framework.test import APIClient, APITestCase class ObjectAPIResponseTest(APITestCase): base_url = 'http://localhost:8000/api/objects/' token = config('LOCAL_API_TOKEN') # token stored in local .env file authenticated_client = APIClient() def setUp(self): self.authenticated_client.credentials(HTTP_AUTHORIZATION='Token ' + self.token) def test_list_object_reaches_api(self): real_response = self.authenticated_client.get(self.base_url) self.assertEqual(real_response.status_code, 200) self.assertEqual(real_response.headers['content-type'], 'application/json') The test fails: AssertionError: 401 != 200 After successfully testing the request with curl, I decided to try to load up requests with the Authorization header instead of using Django REST Framework's APIClient: import requests from decouple import config from rest_framework.test import APIClient, APITestCase class ObjectAPIResponseTest(APITestCase): base_url = 'http://localhost:8000/api/objects/' token = config('LOCAL_API_TOKEN') # token stored in local .env file authentication_header = { 'Authorization': 'Token ' + token } def test_list_object_reaches_api(self): real_response = requests.get(self.base_url, headers=self.authentication_header) self.assertEqual(real_response.status_code, 200) self.assertEqual(real_response.headers['content-type'], 'application/json') This passes, which makes me wonder if I'm somehow using APIClient.credentials() incorrectly, although what I've done seems basically in line with the documentation. Any ideas what I'm doing wrong? -

How to configure URLs within an existing site to direct to certain URLs within a WSGI application using apache?
I have a website that is built using static HTML and CSS being served by Apache at a URL, say www.example.com. On my server, I am also serving several other websites all of which are configured by .htaccess files. I have decided that I would like to add some functionality to my www.example.com website and have written a django application that I would like to include under this domain as part of the website to add functionality. The ultimate goal is to move more of this website over to Django but for now, the django application will only handle 2 functions, collecting feedback - which I'd like to live at www.example.com/feedback - and listing reviews - which I'd like to live at www.example.com/reviews and this has a subpage www.example.reviews/add. But the thing about these 2 features is that they are unrelated to each other and so it does not make sense to have them both under the same URL such as www.example.com/django/feedback(reviews) - I am trying to avoid this or avoid having to split my django application into 2 different applications each with its own wsgi entry point. Because all the individual configs are done with .htaccess files, my main … -

Django can't load media image if DEBUG = False (WARNING:django.request:Not Found: /media/cache/)

Django User-Specific objects via ForeignKey
I am trying to implement a user-specific Shopping Cart, which looks like: class Cart (models.Model): items = [] totalprice = 0 user = models.ForeignKey(User, on_delete=models.CASCADE, related_name="cart", null=True) I have an HTML template that will display an Item and allow the current user to add it to their cart: <ul> <img src={{ item.pic.url }}> <li>{{ item.name }}</li> <li>{{ item.desc }}</li> <li>${{ item.cost }}</li> </ul> <br> <a href={% url 'gallery:add_to_cart' item.id %}>Add to Cart</a> The add_to_cart function is: def add_to_cart (request, id): if request.user.is_authenticated: if not request.user.cart.all(): c = Cart() c.save() request.user.cart.add(c) request.user.cart.all()[0].addItem(Item.objects.get(id=id)) return HttpResponseRedirect('/gallery/') Everything works fine for the first user, but once the first user logs out and another user logs in, their carts seem to be intertwined. Django will create a Cart for the second user, but this Cart will not initialize as empty; it will have the same contents as the Cart of the first user. Upon adding any item to the Cart as the second user, that item will be added to both Carts, and their contents will be identical. Active "Cart" objects upon adding an Item as the second user In short, I can't differentiate between individual users when accessing their Carts. Is there something I … -
