How can we notify the admin about newly added project by user, by defualt project is_active=False
How the admin will be notified on the dashboard (not by mail), and verify all the projects or can decline the projects. class Compaigns(models.Model): nameOfDeceased = models.CharField(max_length=100, null=False, blank=False) nameOfDeceasedEn = models.CharField(max_length=100, null=False, blank=False) projectName = models.CharField(max_length=255, null=False, blank=False) projectNameEn = models.CharField(max_length=255, null=False, blank=False) phone = models.CharField(max_length=255, null=False, blank=False) image = models.ImageField(upload_to='projects/compaigns/%Y/%m/%d', blank=True, null=True) is_compaign = models.BooleanField(default=True) **is_active = models.BooleanField(default=False)** detail = models.TextField(blank=True, null=True) detailEn = models.TextField(blank=True, null=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) suggestedDonation = models.DecimalField( max_digits=10, decimal_places=3, default=0.000) compaignCategory = models.ManyToManyField(CompaignCategory) user = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.nameOfDeceased class Meta: verbose_name_plural = "Compaigns" -
Django: Is there a way to make sure that only a unique FK related object can be added/related to the PK object?
Say there is a poll app and I want a user to vote only once for a poll question. Assume models.py to be as follows, class PollUser(models.Model): username = models.CharField(max_length=120, unique=True) class PollQuestion(models.Model): question = models.CharField(max_length=250) issuing_user = models.ForeignKey(PollUser, on_delete=models.CASCADE) class PollChoice(models.Model): text = models.CharField(max_length=250) votes = models.PositiveIntegerField(default=0) Is there a way to implement this functionality, without making this check in the views? -
Django Rest Framework: How to properly test a ViewSet?
I'm new to testing in DRF. I have the following ViewSet where I'm only allowing the 'List' and 'Retrieve' actions: class RecipeViewSet(mixins.ListModelMixin, mixins.RetrieveModelMixin, viewsets.GenericViewSet): permission_classes = [permissions.AllowAny] queryset = Recipe.objects.filter(visible=True).order_by('-created') pagination_class = RecipeListPagination lookup_url_kwarg = 'recipe_id' def get_serializer_class(self): if self.action == 'list': return RecipeListSerializer elif self.action == 'retrieve': return RecipeDetailSerializer These are the tests I've written so far: class RecipeViewSetTestCase(test.APITestCase): def setUp(self): # Create objects self.category = RecipeCategory.objects.create(name="meals") Recipe.objects.create(name="Pepperoni Pizza", category=self.category, description="It's rounded") Recipe.objects.create(name="Beef Ragu", category=self.category, description="It's moo'") # Get urls self.recipe = Recipe.objects.first() self.list_url = reverse('recipes-list') self.detail_url = reverse('recipes-detail', kwargs={'recipe_id': self.recipe.id}) def test_recipe_list(self): response = self.client.get(self.list_url) self.assertEqual(response.status_code, status.HTTP_200_OK) self.assertEqual(len(response.data['results']), 2) def test_recipe_detail(self): response = self.client.get(self.detail_url) self.assertEqual(response.status_code, status.HTTP_200_OK) self.assertEqual(response.data['name'], self.recipe.name) def test_recipe_create_not_allowed(self): response = self.client.post(self.list_url) self.assertEqual(response.status_code, status.HTTP_405_METHOD_NOT_ALLOWED) def test_recipe_delete_not_allowed(self): response = self.client.delete(self.detail_url) self.assertEqual(response.status_code, status.HTTP_405_METHOD_NOT_ALLOWED) def test_recipe_update_not_allowed(self): response = self.client.put(self.detail_url) self.assertEqual(response.status_code, status.HTTP_405_METHOD_NOT_ALLOWED) def test_recipe_partial_update_not_allowed(self): response = self.client.patch(self.detail_url) self.assertEqual(response.status_code, status.HTTP_405_METHOD_NOT_ALLOWED) I'm not sure if it's necessary to write a test for each method that shouldn't be allowed, or if there is a better way. Also, I'm not sure of what else I should be testing inside this viewset. Does anyone with experience in testing DRF knows how to properly test viewsets? Many thanks! -

Get all entries with price greater than given price in json filed
I have a model Van which van_slug field and a price field I am using MySQL. I have to save different price for all 12 months. I am using jsonfield. class Van(models.Model): slug = models.SlugField(max_length=200) price = JSONField(null=True) I am saving price like this and showing price of current month to visitor. {'January': 987.0, 'February': 567.0, 'March': 567.0, 'April': 456.0, 'May': 6.0, 'June': 654.0, 'July': 456.0, 'August': 456.0, 'September': 456.0, 'October': 546.0, 'November': 89.0, 'December': 456.0} Problem I have to add an filter for min and max price. I don't know how can I do this. I have tried this Van.objects.exclude(price__June__gte=340) but this is raising error Unsupported lookup 'June' for JSONField or join on the field not permitted. I searched the error and found this only work in postgres. I know this solution query = User.objects.filter(data__campaigns__contains=[{'key': 'value'}]) but i don't need exact matching.Is there any other method to filter vans by price? -
How to Get Items in a model connected to another model using a foreign key in detail view in django?

ML and Django: using Conda and Pip depending on what I am doing... no?
So I am starting in Data Science and there are two things I am using quite a bit: Machine learning and Django. I have looked throughout the internet and the two worlds seems to be at different ends - ML going with Anaconda/miniconda and Django with PIP. To me, it makes sense, Anaconda has most of the packages needed for DS and feels a more solid option when using it for those purposes (i.e. data analysis, wrangling, ml modelling, etc). However, for Django, there seems to be everyone (by everyone I mean tutorials and articles on Django) uses PIP. And it makes sense, when deploying a quick app, all you want to do is to create a virtual env, install the needed packages, build the app, pip freeze it and upload to server. Boom. However, the more I look on the internet, everyone seems to be use either Anaconda/miniconda or PIP. Some stuff I read on Stackoverflow mentions using pip inside Anaconda/miniconda's environment... but for that I would have to create a PIP-virtual-environment inside Anaconda/miniconda's environment. As you can see, as a newbie, I feel slightly confused with this. As anyone got experience this? What did you do? -

Django ORM implementation of StdDev on DateTimeField
I'm trying to get the standard deviation of a time in Django. I keep running into django.db.utils.ProgrammingError. I tried it with various data types (DateTimeField, DurationField, IntegerField), also tried casting it first. Event.objects.annotate(StdDev(F('end_ts') - F('start_ts'), output_field=models.DurationField())) Event.objects.annotate(x=Cast(F('end_ts') - F('start_ts'), models.DurationField())).annote(y=StdDev(x, output_field=models.DuratinField)) Given the error, I think it's not yet implemented: django.db.utils.ProgrammingError: function stddev_pop(interval) does not exist LINE 1: SELECT "app_event"."task_id", STDDEV_POP((("app_event"."end_... However, it would save me quite some performance to do it with the ORM compared to manually in Python. If anybody knows a work-around with the ORM, that would be much appreciated! -
Django form data modification with jquery
I am trying to adapt an already working application in Django, but I am quite new to this environment and I am not the original developer so I may have some conceptual errors, but I have not found a way to solve the problem. I have a django model which references a client list: clients = models.ManyToManyField( Client, blank=True, verbose_name=_('Clients'), related_name='clients', ) It is being feed in the admin using the autocomplete feature, obtaining the client data from the other table. This is working perfectly. I want to preload some data based on a select dropbox I have included in the form. On change of the select box, I want to include some values on this manytomany field. I am using jquery to add values to the field, and as far as I have found, I need to add the client references in two places: Add the name and the Id in a Select <select name="clients" id="id_clients" class="admin-autocomplete select2-hidden-accessible" data-ajax--cache="true" data-ajax--type="GET" data-ajax--url="/en/admin/client/client/autocomplete/" data-theme="admin-autocomplete" data-allow-clear="true" data-placeholder="" multiple="" tabindex="-1" aria-hidden="true"> <option value="2355">Client1</option> </select> Add the name in the unordered list (ul) as a new li. <ul class="select2-selection__rendered"> <span class="select2-selection__clear">×</span> <li class="select2-selection__choice" title="Client1"> <span class="select2-selection__choice__remove" role="presentation">×</span>Client1</li> <li class="select2-search select2-search--inline"> <input class="select2-search__field" type="search" tabindex="0" … -
How to signal "ready to accept requests" to Gunicorn in Django application?
Some Context / my problem I develop a Django-appliaction, that is "served" using Gunicorn (configured to use 5 workers) I face the problem that when a new worker is booted after another worker is restarted (I've set max-requests to 1000 and max-requests-jitter to 50), then that new worker's handling of its first request is really slow (approximately ~5 seconds compared to a usual ~0.01 seconds). The extended time for handling the workers' first request coincide well with the time for booting the Django-application. Question Is there a way to signal to Gunicorn that the application is now fully initialized and ready to accept requests? Or alternatively: Can I supply Gunicorn an "I'm ready" HTTP-endpoint on my Django application? Thanks in advance :) Any input or feedback is appreciated -
