Django - what is wrong with my If statement?
Good afternoon all, I inserted an if statement in my template - I only want the form to appear if the product category is "Champagne". For some reason, the product does not appear for champagne products. Here is the code Models.py CATEGORY=( (1,'Rum'), (2,'Gin'), (3,'Whisky'), (4,'Champagne'), (5,'Others'), ) class Product(models.Model): name = models.CharField('Product Name', max_length=120, null=True) category = models.IntegerField(choices=CATEGORY, default=0) description = models.TextField(blank=True, null=True) price = models.DecimalField(null=True, max_digits=6, decimal_places=3) image_url= models.URLField('Image Web Address', blank=True) product_url = models.URLField('Product Web Address', blank=True) class Meta: db_table='Product' def __str__(self): return str(self.name) HTML {% if product.category == 'Champagne' %} <div class="d-flex flex-column mt-4"> <a class="btn btn-outline-secondary btn-sm" href="{% url 'ElderFlowerReview' product.id %}">Tasting Notes</a> </div> {% endif %} Forms.py class DrinkForm(ModelForm): class Meta: model = Product fields = ('name','category', 'description') labels ={ 'name': '', 'category': '', 'description': '', } widgets = { 'name': forms.TextInput(attrs={'class':'form-control', 'placeholder':'Enter name'}), 'category': forms.Select(attrs={'class':'form-control', 'placeholder':'Enter category'}), 'description':forms.TextInput(attrs={'class':'form-control', 'placeholder':'Enter description'}), } -

Placement of {% if form.errors %} on login template
I'm not sure if I'm allowed to ask these types of questions here since it's not a problem per say, so please let me know. But I was wondering for the login.html template on Django: {% extends 'learning_logs/base.html' %} {% block content %} {% if form.errors %} <p>Your username and password didn't match. Please try again.</p> {% endif %} <form method = "post" action="{% url 'login' %}"> {% csrf_token %} {{ form.as_p }} <button name = "submit">log in</button> <input type="hidden" name="next" value="{% url 'learning_logs:index' %}" /> </form> {% endblock content %} How come it checks for the form.errors before the it even processes the form? Thanks for any help on this question. -
Django APITest case not returning anything in get request
I am developing an API with Django, and I also want to test it, but I am having some trouble doing that. I need to test that to a given URL, what is returned is what I expect, and I want to do so with APITestCase of django rest framework. The endpoint is something similar: http://localhost:5000/api/v1/rest_of_url/ When I type it in the browser, it return something similar: {"count": 1, "next": null, "previous": null, "results": [{"stuff": 3, "stuff2": "adf", "stuff3": "asdf", "stuff4": "ff"}]} So, to test that I wrote the following code in Django: class TargetApiTestCase(APITestCase): def test_get(self): response = self.client.get("/api/v1/rest_of_url/", format='json') print(response) print(response.content) print(response.status_code == status.HTTP_200_OK) As response I get the following output from the prints statements: <JsonResponse status_code=200, "application/json"> b'null' True But I should get some data, to check. I know that after that I have to query the db to check and use self.assertEqual, but for now my problem is retrieving data via get Maybe it is only a problem of settings. I tried require responde.data, but it responded with an error. Please, can someone help me? Thank -
How to check if a object has ManyToMany reference in a queryset django?
I have these models in my django project class Question(models.Model): heading = models.CharField(max_length=300) description = models.TextField() class Profile(models.Model): name = models.CharField(max_length=100,null=False,blank=False) completed = models.ManyToManyField(Question) I'm trying to find a optimized way for fetching a list of questions for user it should with whether they have completed it or not. I think it can be done with these quersets:- all_questions = Question.objects.all() completed_questions = Question.objects.filter(profile = profile_instance) where profile_instance is a profile object. Then we can loop through the all_questions and check whether they also exist in completed_questions, but i am not sure whether this is optimized for pagination. I'm using Django-Rest Framework pagination. -
How to write changes in fields to LogEntry?
I had a task to create action which will change status of object(s). Action is already create. Code for example: class MyAdmin(admin.ModelAdmin): actions = ['decline_status', ] def decline_status(self, request, queryset): decline_status = constants.DECLINED.value objects_to_decline = queryset.exclude(status=decline_status).filter(status=decline_status) if objects_to_decline.count() > 0: objects_to_decline.update(status=decline_status) But now I have a problem: I need to write changes which were called by decline_status action to LogEntry table. Nothing is happend when i use LogEntry.objects.create(different_kwargs). And I'm trying to use self.log_change(request, obj, some_change_message), but changes appear only on the main page of admin in the window: recent actions window I need to write changes to LogEntry like they are written after default action delete_selected. Can you help me? -
How to update M2M field related data attributes in Django

Django: Prepopulate extra fields in a Formset with a ManyToMany Model
I have two models with a ManyToMany (M2M) relationship. In order to have extra fields on the M2M Model, I defined a through= model. I tried setting up a inlineformset_factory, using parent=ChildModel and model=ParentModel.parent_child.through as described in this thread pendant to inline formsets for many-to-many relations. But it did not solve my issue. How can I access (i.e. prepopulate) and update the extra fields of the M2M model, when using formsets? models.py class ParentModel(models.Model): name = model.CharField() parent_child = model.ManyToManyField(ChildModel, through='ParentChildModel') class ChildModel(models.Model): name = model.CharField() class ParentChildModel(models.Model): parent = models.ForeignKey(ParentModel, on_delete=models.CASCADE) child = models.ForeignKey(ChildModel, on_delete=models.CASCADE) extra_field_1 = models.CharField() forms.py class ChildForm(forms.ModelForm): class Meta: model = ChildModel fields = '__all__' ChildFormset = modelformset_factory(ChildModel, form=ChildForm, extra=0, can_delete=True, can_order=True, ) -
Can't load local images with HTML
I am developing a simple site with Django, and wanted to load some images locally to some pages. But it doesn't load for some reason. I know there are similar questions, and from what i understand; a-) It can be a directory problem, html file and img file is in the same directory. Still doesn't work; directory, and the html file. I tried moving the img.jpg to the templates/images directory and try <img src="images/img.jpg" height="400" width="374"> within the html file but that didn't work either. b-) It could be a typo, but from the images up there that shouldn't be the case either. c-) Files could be corrupted, I can open the image with browsers and tried using different images too. d-) Img could be restricted, but that is not the case either. I think. Trying to fix this for two days now, thought for some reason usage of extend or block might cause some problems and tried without them, still no good. and as i said its only a problem with local files. Can use files with direct link. Thanks in advance, sorry for any problems with the format. -
Recipient variables have no value in django-anymail and Mailgun
I'm trying to add some metadata to emails, but never receive it in logs and in webhooks. Here is what I'm doing: recipient_variables = {recipient:metadata} msg.merge_metadata = recipient_variables This is how the msg.merge_metadata looks like: {'EMAIL': { 'submission_id': 'ID'}} This is what data looks like in Mailgun web logs: "user-variables": { "submission_id": "%recipient.v:submission_id%", }, And webhook just receives: {'submission_id': ''} I also tried msg.extra_headers["X-Mailgun-Recipient-Variables"] = json.dumps(recipient_variables) It also hasn't changed anything much, but webhook now receives this instead> {'submission_id': '%recipient.v:submission_id%'} Am I doing anything wrong? The whole process seems to be pretty straightforward. — Anymail version — 8.6 ESP (Mailgun, SendGrid, etc.) — Mailgun django 4.0.4, requests 2.27.1, python 3.10 Settings: ANYMAIL = { "MAILGUN_API_KEY": "", "MAILGUN_SENDER_DOMAIN": '', "MAILGUN_API_URL": "https://api.eu.mailgun.net/v3", "WEBHOOK_SECRET" : "", "MAILGUN_WEBHOOK_SIGNING_KEY": "", } -
Pagination with ordering and other get variables
In a class based ListView, while rendering i want to dynamically change the no of items shown per page and the sorting order of those items. I referred to this question and the answer by skoval00 works for me when i change the ordering and change the pages. But as soon as i change the no of items per page, my ordering is lost. For ex: my generic view links to http://127.0.0.1:8000/marketplace/. If i set the pagination to 10 items per page. The url changes to http://127.0.0.1:8000/marketplace/?paginate_by=10 But now if i change my ordering too, i expect something like http://127.0.0.1:8000/marketplace/?paginate_by=10&ordering=end_date but i get http://127.0.0.1:8000/marketplace/?ordering=end_date And the pagination changes to the default value. Same thing happens vice-versa. If i order first and then change pagination, then i lose the ordering once the pagination changes. How do i preserve the first argument while adding the second one? Here is the relevant class in views.py class CatalogueListView(ListView): model = Catalogue context_object_name = 'catalogues' template_name = 'marketplace/catalogue_list.html' paginate_by = 5 ordering = ['end_date'] def get_queryset(self): if self.request.GET.get('ordering'): ordering = self.request.GET.get('ordering') else: ordering = 'end_date' query_set = Catalogue.objects.filter(admin_approved=True, end_date__gt=timezone.now()).order_by(ordering) return query_set def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) if self.request.GET.get('paginate_by'): context['paginate_by'] = self.request.GET.get('paginate_by') else: context['paginate_by'] = … -

Does Django Optimize the query if it gets run multiple times with the same filter?
class MyModel(models.Model): task_id = models.UUIDField() task_type = models.ForeignKey(ContentType, on_delete=models.CASCADE, related_name='+') task = GenericForeignKey('task_type', 'task_id') ..... @property def task_description(self): if self.task_status === 'pending': return 'Pending Task' else: task = Task.objects.filter(self.task_id).first() return task.name or '' In case self.task_status is not pending, then for each task, it looks up the Task table for the name. My Question. suppose task ids [1,2,3,3,3] then what will be the queries that get run ? is this N+1 problem ? for id 1, it checks the Task table where id = 1. for 2 3 it does too. But for id == 3, does it look up the table 3 times with same filter like where id = 3 ? -
How can I deploy code to production when I am running celery, redis, django with docker compose?
I am running celery, Redis, Django, and flower containers with docker compose. The docker-compose.yml file is similar to this tutorial. The whole app can run very well. The problem is when I change the code and deploy it to production. I found that the code was often not updated and this caused errors. For example, I try to change the celery task code or add new tasks. The updated tasks cannot be deployed From restarting the workers, I tried to run the commands: celery multi start 1 -A proj -l INFO -c4 --pidfile=/var/run/celery/%n.pid celery multi restart 1 --pidfile=/var/run/celery/%n.pid kill -HUP $pid But the task is not updated after my testing. The task is still loading the old code. How can I deploy code to production? Should I restart the container with? docker-compose restart celery From the celery docs, it says that: For production deployments you should be using init-scripts or a process supervision system (see Daemonization). The Daemonization is completely not related to docker. I don't understand how Daemonization is related to deployment with docker / docker compose. Actually I don't understand why Daemonization is related to deployment from the official docs. -
Wagtail add bulk actions to ModelAdmin IndexView
I would love to add custom bulk actions to a ModelAdmin index view. Is that possible already or a feature request potentially? The ModelAdmin module’s IndexView is great to filter a larger number of pages. I would love to select a bunch of these pages and start a custom bulk action like "publish", "unpublish" or "add to another page". Alternatively I could try to add more attributes/columns to the page Explorer, which already offers these bulk actions. But the ModelAdmin module was added to Wagtail to do exactly that. So I think, that adding bulk actions to the ModelAdmin is the way to go. -
