Django MoneyField: Invalid value for MoneyField
I'm having slight of a problem while using MoneyField in Django. I have 2 models: Work and Price. And Price gets Work id as a Foreign Key. In Postman I'm trying to post a Work with a Price, but I keep getting an error. Here is my work_model: from django.db import models from django.contrib.auth import get_user_model User = get_user_model() class Work(models.Model): user = models.ForeignKey(User, null=True, on_delete=models.SET_NULL) name = models.CharField(max_length=200) length = models.IntegerField(null=True) width = models.IntegerField(null=True) def __str__(self): return "{}".format(self.name) And here my price_model from django.db import models from .model_work import * from djmoney.models.fields import MoneyField class Price(models.Model): work = models.OneToOneField(Work, on_delete=models.CASCADE, related_name='price') price = MoneyField(max_digits=19, decimal_places=4, default_currency='USD', null=True) shipping = models.IntegerField(null=True) total = models.IntegerField(null=True) def __str__(self): return "{}".format(self.price) When I'm posting a Work in Postman: { "user":"2", "name":"work 20", "price": [ { "price":20, "price_currency":"USD", "shipping":12, "total":32 } ], "length":"50", "width":"60" } I keep getting this error: ValidationError at /works/ ["Invalid value for MoneyField: [OrderedDict([('price', <Money: 20.0000 USD>), ('shipping', 12), ('total', 32)])]."] I've looked everywhere but can't manage to understand my error, does anyone have a clue? Thanks for your responses! -

Decorators for authentication using oauth in Django
I am trying to complete Oauth2 using a Decorator in Django. Until before I tried using decorator, I was doing it using this endpoint oauth (which works alright): Note: OSCAR_CALLBACK_URL is URL for oauth endpoint only def oauth(request): if not request.GET.get('oauth_verifier'): return oscar_oauth_init(request) else: res = oscar_oauth_accesstoken(request) return res def oscar_oauth_init(request): oauth = OAuth1(OSCAR_CLIENT_ID, client_secret=OSCAR_CLIENT_SECRET) url=OSCAR_INIT_URL+OSCAR_CALLBACK_URL r = requests.get(url=url, auth=oauth) credentials = convert(parse_qs(r.content)) resource_owner_key = str(credentials.get('oauth_token')[0]) resource_owner_secret = str(credentials.get('oauth_token_secret')[0]) verifier = oscar_oauth_auth(resource_owner_key) request.session['resource_owner_key'] = str(resource_owner_key) request.session['resource_owner_secret'] = str(resource_owner_secret) request.session['verifier'] = str(verifier) return verifier def oscar_oauth_accesstoken(request): verifier = request.GET.get('oauth_verifier') resource_owner_key = request.GET.get('oauth_token') resource_owner_secret = request.session.get('resource_owner_secret') oauth = OAuth1(OSCAR_CLIENT_ID, client_secret=OSCAR_CLIENT_SECRET, resource_owner_key=resource_owner_key, resource_owner_secret=resource_owner_secret, verifier=verifier) r = requests.get(url=OSCAR_TOKEN_URL+verifier, auth=oauth) credentials = convert(parse_qs(r.content)) resource_owner_key = credentials.get('oauth_token')[0] resource_owner_secret = credentials.get('oauth_token_secret')[0] request.session['resource_owner_key'] = str(resource_owner_key) request.session['resource_owner_secret'] = str(resource_owner_secret) return credentials This endpoint was required to be called before other API calls that needed user to be authorized.

How to exchange base docker images safely, when image is down?
I'm learning Docker. Right now I'm working on a Django app and I want to make a container. I'm on Windows 10. When I run docker-compose build, I get: $ docker-compose build Building movies Step 1/9 : FROM python:3.8.2-alpine 3.8.2-alpine: Pulling from library/python Service 'movies' failed to build: no matching manifest for windows/amd64 10.0.18363 in the manifest list entries As far as I've investigated, I'm getting that error because the image is down (because of a bug of docker?) a) https://github.com/nginxinc/docker-nginx/issues/230 b) https://github.com/docker-library/official-images/issues/3835 So what image can replace this one: FROM python:3.8.2-alpine???

How to mock out custom throttle class for testing in django-rest-framework?
I have a custom throttle class like: (print statements are for debugging :)) in api.throttle.py print("befor CustomThrottle class") class CustomThrottle(BaseThrottle): def __init__(self): super().__init__() print("initializing CustomThrottle", self) self._wait = 0 def allow_request(self, request, view): print("CustomThrottle.allow_request") if request.method in SAFE_METHODS: return True # some checking here if wait > 0: self._wait = wait return False return True def wait(self): return self._wait my api.views.py is like: from api.throttle import CustomThrottle print("views module") class SomeView(APIView): print("in view") throttle_classes = [CustomThrottle] def post(self, request, should_exist): # some processing return Response({"message": "Done."}) and my tests is api/tests/test_views.py: @patch.object(api.views.CustomThrottle, "allow_request") def test_can_get_confirmation_code_for_registered_user(self, throttle): throttle.return_value = True response = self.client.post(path, data=data) self.assertEqual( response.status_code, status.HTTP_200_OK, "Should be successful", ) @patch("api.views.PhoneConfirmationThrottle") def test_learn(self, throttle): throttle.return_value.allow_request.return_value = True response = self.client.post(path, data=data) self.assertEqual( response.status_code, status.HTTP_200_OK, "Should be successful", ) the first test passes correctly but still the CustomThrottle class is instantiated but the allow_request method is mocked; the second test shows that neither CustomThrottle class is mocked nor the allow_request method and it fails with status 429 (CustomThrottle has a throttle rate of 2 minutes). -

How do I allow users of Django to create their own personal blog?
I have created a Django site that allows users to post and comment on these posts. I thought it would be a good idea to allow each user to have their own "page" where they can allow invited members this page to basically use the blog feature that I've designed. The only thing I can't figure out is how to allow users to dynamically create a page that is specific to them. Can this be done with one template? -

Posting product quantity in a Django form
I'm working with an e-commerce webapp and in the product detailed-view I want to give the option to set the quantity before the checkout. I thought I could do this with a simple form: class QuantityForm(forms.Form): quantity = forms.IntegerField(widget=forms.NumberInput(attrs={'class':'required'})) And then implementing it to the view: class BagDetailView(DetailView): context_object_name = 'ctx' model = Bag template_name = 'product_page.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['form'] = QuantityForm(initial={'quantity':1}) context['Jackson'] = Bag.objects.get(title = 'Jackson') context['Anthony'] = Bag.objects.get(title = 'Anthony') return context But the problem is the POST request. I cannot call the render() function because I have another view to handle the checkout, so I need to call redirect(). This is the code: def post(self, *args, **kwargs): form = QuantityForm() b = Bag.objects.get(slug=kwargs['slug']) if form.is_valid: return redirect(b)# calls get_absolute_url which redirects to checkout/<slug> And I cannot access the data that I'm posting in the other view. I think it's bad practise to post data like this to another view, but I couldn't come up with anything but that. Is there any other way to pass that data into the other view? Note: I'm not using a cart system because I'm only dealing with two products. -

Trying to generate separate DOB fields on edit profile view - Django
I have been looking around and trying to get a drop down menu for Date of Birth e.g. dd/m/yyyy for my project, I'm currently using the following: This code snippet is from the edit profile page of my web application. YEARS= [x for x in range(1940,2021)] birth_date = forms.DateField(label='What is your birth date?', initial="1990-06-21", widget=forms.SelectDateWidget(years=YEARS)) When viewing the actual edit page, this does not appear to render. However, if you were to either inspect element, or view page source you can see the following: <select name="birth_date_month" required id="id_birth_date_month"><option value="1">January</option><option value="2">February</option><option value="3">March</option><option value="4" selected>April</option><option value="5">May</option><option value="6">June</option><option value="7">July</option><option value="8">August</option><option value="9">September</option><option value="10">October</option><option value="11">November</option><option value="12">December</option></select><select name="birth_date_day" required id="id_birth_date_day"><option value="1">1</option><option value="2">2</option><option value="3">3</option><option value="4">4</option><option value="5">5</option><option value="6">6</option><option value="7">7</option><option value="8">8</option><option value="9">9</option><option value="10">10</option><option value="11">11</option><option value="12">12</option><option value="13">13</option><option value="14">14</option><option value="15">15</option><option value="16">16</option> --- Truncated for demo purposes --- Model: birth_date = models.DateField(null=True, blank=True) I am however able to use and view the following successfully, although this is not what I want to view: dob = forms.CharField(widget=forms.widgets.DateTimeInput(attrs={"type": "date"})) However, this just looks like one of those crappy date selectors that aren't particular great... Inefficient date selector Can someone point me in the right direction please? -

Django Channels Realtime Chat
Django channels Realtime chat Task build realtime chat, as well as sending / receiving notifications not related to the chat. A total of 2 real-time functions. Tools backend - django frontend - Android Mobile App Problem on a localhost, the code works, messages reach the client. Deployed on Heroku, the tariff is free. It turned out that there is a limit on connections = 20 (which is not enough for one user for 10 minutes). After each request, a new connection is created through ASGI, everything is ok for WSGI. To the limit - everything works, but when there are 20 connections, messages reach 2-3 times. Attempts to solve 1. I registered in the code close_old_connections, it did not work to kill the connection. Those for each message creates a new connection. Googled for several days, did not find a solution on this issue. 2. I tried with both Daphne and Uvicorn - the effect is the same Question maybe django-channels is not a suitable option for the task. Perhaps it’s worth abandoning Heroku, deploying to another hosting and raising Nginx, and all the restrictions will disappear?

Porting and existing nested set hierarchy
I have a nested set category table developed with the PHP ORM Doctrine and I would like to port it to a Django app. I started porting it to django-treebeard, but I am having difficulties and I am not sure it can work. The original table had the needed fields lft, rgt and depth, so I added the tree_id field. I also had a foreign key to Accounts with one tree/account. Thus the table hold multiple independent trees that are not under a common root, with the lft and depth columns starting at 1 for each tree. So basically one nested set for each account in the table. I can add nodes to a tree just fine, but when I call the get_last_child method, I get nodes from other accounts. Does anyone know if there is a way to use treebeard, mptt or any other package without having to restructure the trees? -

How to plug the reponse of a django view GET request into the same view as a POST request during testing?
I have a Django function-based form view that initializes a form with default data on a GET request, and saves the model object on a POST request: def copy(request, ann_id): new_ann = get_object_or_404(Announcement, pk=ann_id) new_ann.pk = None # autogen a new primary key (quest_id by default) new_ann.title = "Copy of " + new_ann.title new_ann.draft = True new_ann.datetime_released = new_ann.datetime_released + timedelta(days=7) form = AnnouncementForm(request.POST or None, instance=new_ann) if form.is_valid(): new_announcement = form.save(commit=False) new_announcement.author = request.user new_announcement.datetime_created = timezone.now() new_announcement.save() form.save() return redirect(new_announcement) context = { "title": "", "heading": "Copy an Announcement", "form": form, "submit_btn_value": "Create", } return render(request, "announcements/form.html", context) I can't figure out how to test the form.is_valid() branch when the form is posted, without manually providing the form data to self.client.post(url, form_data) in my view. What I want to actually test is that the result of the get provides valid default data for the form that can then be submitted via post request. But I can't figure out how to change the repsonses, so that the form data resulting form the get request is then fed into the form data provided to the post request. EDIT I found the location of the form in the get response, but …
