Django Rest universal linking -- json file path not found
I have a Django REST framework that is integrating universal app linking for iOS https://developer.apple.com/library/archive/documentation/General/Conceptual/AppSearch/UniversalLinks.html The main point is that I have a json file called "apple-app-site-association" in my root directory (as instructed) that controls the redirect. When I put this through an aasa validator https://branch.io/resources/aasa-validator/ it returns a 400. My server logs show Not Found: /.well-known/apple-app-site-association I can't find any resources doing this with django, so I'm a little stuck on what to try or do next. -
expecting one result, but django .filter() returns multiple
I am chaining the filters and expecting one result to return -because according to the conditions result should be one- but it returns related rows as well... // taking the ID from the parent table. pid = Budgets.objects.filter(project_name=direct["project_name"]).values("id")[0]["id"] // checking the row exist or not. exists = Advertisements.objects.filter(budgets_id=pid).filter(saved_date="2020-02").filter(ad_kind="gsn").exists() if exists == True: // if it's exist then return it with the according criterias value = Advertisements.objects.filter(budgets_id=pid).filter(saved_date="2020-02").filter(ad_kind="gsn").values_list("ad_kind", flat=True)[0] print(value) // the problem occurs here. normally filter(ad_kind="gsn") should filter it till gsn left. But it doesn't. And it return other kinds too... Any idea what can be causing this problem? -

Which URL does CreateView in Django redirects to when the success_url is not provided?
I am learning Class-based views in Django(inheriting from generic views) and stumbled upon a code for CreateView which did not provide any success_url. But after creation, I am getting redirected to DetailView (i.e, the page describing a particular object, in this case the object just created). I am not sure how this redirection is happening. Can anyone help me with this? # ...other imports... # ... from django.views.generic.edit import CreateView #... other views... class TweetCreateView(FormUserNeededMixin, CreateView): form_class = TweetModelForm template_name = "tweets/create_view.html" class TweetDetailView(DetailView): model = Tweet #...other views... Thanks. -
Asking user to select a local directory
I've been looking everywhere in the hope of finding a good implementation of allowing a user to select a local directory for, in this case, selecting where to download files. The best method I found was through tkinter with the filedialog method but I thought this couldn't be the best approach. -
Error in Django ModelForm. Select a valid choice. That choice is not one of the valid choices
I have a Model and a ModelForm. The ModelForm has a dependent dropdown list implemented with JQuery. The category dropdown changes accordingly each time a choice from the gender dropdown is selected (Done with JQuery). Whenever I try to save the ModelForm in my views, I get an error saying that the choice that I have selected is not valid. Does it have to do with the choices/options to the category dropdown being added after a choice from the gender dropdown has been selected? Does it cause some conflict with the default empty two-tuple of the category field? The errors occur on the category field. In models.py, GENDER_CHOICES = [ ('Male', 'Male'), ('Female', 'Female'), ] class Person(models.Model): name = models.CharField(max_length=50, unique=True) gender = models.CharField(max_length=7, choices=GENDER_CHOICES) category = models.CharField(max_length=20, choices=[('', ''), ]) In forms.py, class PersonForm(ModelForm): class Meta: model = Person fields = [ 'name', 'gender', 'category', ] In views.py, def personform_page(request): context = {} if request.method == 'POST': personform = PersonForm(request.POST) if personform.is_valid(): personform.save() return redirect('personform_page') context['personform'] = personform else: personform = PersonForm() context['personform'] = personform context['male_categories'] = MALE_CATEGORIES context['female_categories'] = FEMALE_CATEGORIES return render(request, 'app1/personform_page.html', context=context) In app1/personform_page.html, <form class="form-class" action="" method="post" enctype="multipart/form-data"> {% csrf_token %} {% for field in … -

Too much view logic in django template
i am currently building an e commerce platform. I am working on the Order part of the app which creates an order after two people agree to enter into a transaction. Issue is that the order model has a lot of fields and as i want my template to look different depending on many values such as; has payment been made? Has the product been shipped? has a dispute been raised? I also want the page to look different depending on if its the buyer viewing the page or the seller. Obviously if the seller is viewing the page i dont want him to see the checkout button, or the buyer to see the mark item as posted etc. So i currently have this working however there is a LOT of if statements in my template to do so and the view has a lot of logic as well. My question is, is there a better (more efficient and faster) way to do this as i know most logic should be kept out of the template. If this won't slow my site down then that is acceptable but if it is then i really need to change it. The Model … -

Why is my Django serializer telling me an attribute doesn't exist when I see it defined in my model?
I'm using Python 3.7 and the Django rest framework to serialize some models into JSOn data. I have this data = { 'articlestats': ArticleStatSerializer(articlestats, many=True).data, and then I have defined the following serializers ... class LabelSerializer(serializers.ModelSerializer): class Meta: model = Label fields = ['name'] ... class ArticleSerializer(serializers.ModelSerializer): label = LabelSerializer() class Meta: model = Article fields = ['id', 'title', 'path', 'url', 'label'] class ArticleStatSerializer(serializers.ModelSerializer): article = ArticleSerializer() class Meta: model = ArticleStat fields = ['id', 'article', 'score'] I have defined my Label model like so ... class Label(models.Model): name = models.CharField(max_length=200) def __str__(self): return self.name class Meta: unique_together = ("name",) but I'm getting this error when Django processes my serialize line ... AttributeError: Got AttributeError when attempting to get a value for field `name` on serializer `LabelSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `str` instance. Original exception text was: 'str' object has no attribute 'name'. Not sure why it's complaining. The "name" attribute is right there. What else should I be doing? -
Creating .ebextensions directory in Django on Mac
I am trying to add an .ebextensions directory to my site root in Django. In the terminal I was able to create the file with no error, cd into the directory, and then add a django.config file (following this tutorial: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html#python-django-configure-for-eb) However, when I view the parent directory of the .ebextensions directory, the file is not there! When I try recreating the directory in the terminal I get the following error: "mkdir: .ebextensions: File exists" When I try to manually create a folder titled .ebextensions in Finder, I get the following error: "You can't use a name that begins with a dot "." because these names are reserved for the system. Please choose another name." Any advice? -

can I filter against the URL with a Django Rest Framework ViewSet?
Is there a way to filter against the URL (as described here) using a DRF ViewSet? I have the following sort of code: models.py: class Author(models.Model): name = models.CharField() class Book(models.Model): title = models.CharField() author = models.ForeignKey(Author, related_name="books") views.py: class BookViewSet(viewsets.ReadOnlyModelViewSet): serializer_class = BookSerializer def get_queryset(self): author = self.kwargs["author"] return Book.objects.filter(author__name=author) urls.py: api_router = SimpleRouter() api_router.register(r"books/<str:author>", BookViewSet) urlpatterns = [ path("", include(api_router.urls)) ] But this pattern actually matches the URL /books/<str:author> (with the angle brackets) instead of letting my enter something like /books/shakespeare and get back all books with the author "shakespeare". Is it possible to do this kind of a filter with a ViewSet? -

Saving the form and updating the 'PackingLists' model is no issue, creating the document is no issue, but how to automatically create a new object in PackingListDocuments I am not sure. models.py class PackingList(models.Model): Reference_Number = models.CharField(max_length=100, null=True) ... class PackingListDocuments(models.Model): Reference_Number = models.ForeignKey(PackingList) PackingListDocument = models.FileField(upload_to='media') views.py def PackingListView(request): if request.method == "POST": form = PackingListForm(request.POST) if form.is_valid(): ... elif 'save' in request.POST: context = request.session['data'] = form.cleaned_data pdf = render_to_pdf('packlist_preview.html', context) filename = "YourPDF_Order{}.pdf" PackingListDocuments.PackingListDocument.save(filename, File(BytesIO(pdf.content))) #this does not work form.save() messages.success(request, "Success: Packing List Has Been Created!") return redirect('HomeView') else: form = PackingListForm() return render(request, 'packlist.html', {'form': form}) -
Django REST: Serialize a ManytoMany field that is within another ManytoMany field
I have a three models with Opportunity being the Serialized model. The Broker model is a M2M field within the Project field. Then the ServiceLines model is a M2M field of Broker model. When I serialize my data, I receive all information about the Broker model related to the Opportunity, however, I do not receive any information on the ServiceLine within the Broker M2M. The following are my Serializers: class ServiceLineSerializer(serializers.ModelSerializer): class Meta: model = ServiceLine fields = ['id', 'servicelinename'] depth = 1 class BrokerSerializer(serializers.ModelSerializer): class Meta: model = Broker fields = ['id', 'fullname', 'primarybl'] depth = 1 primarybl = ServiceLineSerializer(many=True) class ProjectSerializer(serializers.ModelSerializer): class Meta: model = Opportunity fields = [*] depth = 1 broker = BrokerSerializer(many=True) And my models: class Broker(models.Model): firstname = models.CharField(max_length=100, default= "First Name") lastname = models.CharField(max_length=100, default= "Last Name") fullname = models.CharField(max_length=100, default= "Full Name") primarybl = models.ManyToManyField('ServiceLine') class ServiceLine(models.Model): servicelinename = models.CharField(max_length=100) def __str__(self): return self.servicelinename class Opportunity(models.Model): broker = models.ManyToManyField('team.Broker') Thanks for your time! -
Refreshing request in Django
I'm pretty new to Django and I'm trying to build a website, which finds a movie for you. My problem is that sometimes API doesn't find anything and I'm getting error "query must be provided". I'd like to know if there is any way to refresh the request until query is provided? here is my code view def result(req): search_result = req.GET.get('search') movie_genre = req.GET.get('movie_genre') if search_result == '' and movie_genre == 'none': return redirect('/') else: result = search_movie(search_result) if result == None: return redirect('/') else: movie_title = result[0] movie_id = result[1] movie_release_date = result[2] movie_overview = result[3] number_of_movies = result[4] return render(req, 'movie_app/result.html', { 'movie_title': movie_title, 'movie_id': movie_id, 'movie_release_date': movie_release_date, 'movie_overview': movie_overview, 'number_of_movies': number_of_movies, }) Here especially is where I need help: if result == None: return redirect('/') From UX point it seems dumb to redirect to homepage. I'be really thankful for help!
