Django file upload: Upload form has no save method
I got the following situation: model.py class DocumentUploadForm(forms.Form): file = forms.FileField( validators=[validate_file_extension], required=True ) author = forms.CharField(required=True) class Meta: model = Document fields = ['file', 'author'] forms.py class Document(models.Model): file = models.FileField(upload_to='documents/') author = models.CharField(max_length=50) date = models.DateField(auto_now=False, auto_now_add=True) imported = models.BooleanField(default=False) views.py if request.method == "POST": form = DocumentUploadForm(request.POST, request.FILES) if form.is_valid(): # author = request.POST.get('author', None) # if author is None: # return HttpResponseRedirect("/") # document = Document(file=request.FILES['file'], author=author) # document.save() form.save() # no save() method !! Error: 'DocumentUploadForm' object has no attribute 'save' I don't like the way by creating a document object by my self and fill in all the necessary information. This leads to a lot of error handling that I don't want to have. So I had a look at https://docs.djangoproject.com/en/1.8/topics/http/file-uploads/#handling-uploaded-files-with-a-model They describe the exact way I implemented but I don't know why I get the AttributeError. Any help would be nice! aronadaal -

Badly affecting performance in populating ManyToMany field values in rest api (using django rest framework)
As I'm using django rest framework for building my product api. Here is my model in models.py class Tag(models.Model): tag = models.CharField(max_length=10, unique=True) class Product(models.Model): product_name = models.CharField(max_length=100) tag = models.ManyToManyField(Tag, blank=True, default=None, related_name='product_tag') serializers.py : class TagSerializer(serializers.ModelSerializer): class Meta: model = Tag fields = '__all__' class ProductSerializer(serializers.HyperlinkedModelSerializer): tag = TagSerializer(many=True, read_only=True) class Meta: model = Product fields = '__all__' views.py : class ProductViewSet(viewsets.ModelViewSet): queryset = Product.objects.all() serializer_class = ProductSerializer I have given the url for ProductViewset, so when I hit the api it gives me the results as well but it takes too much time to load, it takes around 2 minutes to give me the response. I'm having 2000 product objects in database which needs to be populated. When I exclude the 'tag' field in "ProductSerializer", response comes very fast with all 2000 records. Please suggest where is the loophole, why its affecting performance so much especially when I add this ManyToMany field. -
How to use stream-django with djangorestframework
I'm new to django and I'm currently working on a small project using djangorestframework. I was having issues creating an activity stream but I stumbled on getstream.io(stream-django) and I've been unable to wrap my head around it. I'll like to see a example of how an activity stream can be created using DRF and stream-django. I'll just drop the model and serializer i'm working with. Many thanks. Models.py class Imprest(models.Model, Activity): user = models.ForeignKey(User, on_delete=models.CASCADE) description = models.TextField() amount = models.PositiveIntegerField() is_approved = models.BooleanField(default=False) created_at = models.DateTimeField(default=datetime.now) def __str__(self): return 'Raised by: {}'.format(self.user) serializers.py class ImprestSerializer(serializers.ModelSerializer): user = UserSerializer(read_only=True, required=False) class Meta: model = Imprest fields = '__all__' def get_validation_exclusions(self, instance=None): exclusions = super(ImprestSerializer, self).get_validation_exclusions(instance) return exclusions + ['user'] views.py class ImprestViewSet(ModelViewSet): queryset = Imprest.objects.all() serializer_class = ImprestSerializer permission_classes = permissions.IsAuthenticated, def get_permissions(self): if self.request.method in permissions.SAFE_METHODS: return permissions.AllowAny(), return permissions.IsAuthenticated(), def perform_create(self, serializer): instance = serializer.save(raised_by=self.request.user) -
Database to store models with variable number of fields
I'm implementing grammatical vocabulary, each part of speech in different languages has different number of fields. Currently I use Postgresql. For example, class EnNoun(Model): word = CharField(max_length=75) class FrNoun(Model): singular_masculine = CharField(max_length=75) plural_masculine = CharField(max_length=75) singular_feminine = CharField(max_length=75) plural_feminine = CharField(max_length=75) Note that there are many languages and many parts of speech. Next, I have Translation table, where I store translations. class Translation(Model): from_word_id = UUIDField() part_of_speech = CharField(max_length=25) # (noun, adjective etc.) to_word_id = UUIDField() from_lang = CharField(max_length=2) # (en, fr, it etc.) to_lang = CharField(max_length=2) # (en, fr, it etc.) The problem is with searching translation. If user enters "look" and wants to translate from English into French, then I need to query all tables (en tables to be precise) to determine whether there is such word. Then I query Translation to find translation and again query Word tables to fetch info about words. Pretty inefficient. Things got worse when I want to sort translations alphabetically (like in physical vocabulary). I heard about mongodb. Is it capable of storing such data? I want to preserve tables, because each table has its own behavior (__str__ method etc.) Can I write in Mongodb something like class Translation(Model): from_word = SomeObjectField() … -
Serving custom forms from Django's wagtail CMS

Cloning a heroku hosted django project to your local machine
I'm new to python, Django, heroku and even PostgreSQL but am working on a Django project with a team of 3 devs (they set it up), so I'm trying to set it up on my local machine so I can start developing. Firstly I cloned the repository to my local machine, there was a requirement.txt file, so I ran pip install -r ./requirements.txt to install all the python packages the project uses. Theres a runtime.txt file which specifies python 3.5 so I need to upgrade that. I see that gunicorn is one of the packages in requiments.txt, so I'm guessing I need to use that as the web server. Heres the packages in requirements.txt that look important to me: Django==1.9.6 gunicorn==19.5.0 psycopg2==2.6.1 boto3==1.3.1 boto==2.40.0 whitenoise==3.2 django-extensions==1.6.7 The site also has a .buildpacks file, which seems to be a heroku specific thing: https://github.com/a2ikm/heroku-buildpack-libjpeg62 https://github.com/heroku/heroku-buildpack-python https://github.com/rafaelp/heroku-buildpack-wkhtmltopdf Theres a Procfile that contains this: web: gunicorn myproject.wsgi --log-file - worker: celery worker --app=genome.tasks.app -l info --beat I'm wondering what the best way to do this is. Is there a way to automatically generate a virtual environment that has all the requirements and software specified in the project? I'm already using a virtual dev environment … -

Custom Error 400/500 page in Django
There is some strange problem. When I do like this def error_page(request): return HttpResponseBadRequest it raises My custom error page that I listed in main URLconf. But when i pass and exception there - I got just a blank page with the text of exception. For example, view is something like this: def error_page(request): return HttpResponseBadRequest('The error text') And I get a blank page with the "The error text" text in body, but not my custom error page. How can I make Django use my Error page Template, but with error text? -

Django-assets not compiling
Installed django-assets with pip install django-assets into my virtualenv environment.

Why would Django respond with differently to the same request
We've recently inherited a Django project which is new territory for me. In debugging an issue I've come across something I've never seen before in my 20 years of programming. I have an API (written in Django) which has multiple end points (usual user profile stuff). When I make a GET request I get a response in the format I expect, however each time I make the request the subset of data is different. I have attached 3 screenshots of the Postman request immediately following new user sign up, these are taken seconds apart with no changes to the data. I can continually make the requests and cycle through the 3 states. This is the code for the endpoint: class UserProfile(RetrieveUpdateDestroyAPIView): serializer_class = SRUserSerializer queryset = SRUser.objects permission_classes = (IsAuthenticated,) def retrieve(self, request, *args, **kwargs): instance = request.user instance.not_now_count = instance.not_now.all().count() serializer = self.get_serializer(instance) return Response(serializer.data) The only thing I can assume is that the serializer is making additional data requests to the database but returning the data before they have necessarily returned. Would there be a way to identify this? What else can I provide to help identify the issue? This is a Django 1.9 instance running on AWS … -

If someone could help identify why it would be very helpful. detail.html <h1>{{ question.question_text }}</h1> {% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %} <form action="{% url 'polls:vote' question.id %}" method="post"> {% csrf_token %} {% for choice in question.choice_set.all %} <label for="choice{{ forloop.counter }}">{{ choice.choice_text }} </label><br /> <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.id }}" /> {% endfor %} <input type="submit" value="Vote" /> </form> Views.py from django.http import HttpResponseRedirect, HttpResponse from django.template import loader from django.urls import reverse from django.shortcuts import get_object_or_404, render from .models import Choice, Question # Long Method of return HttpResponse # def index(request): # latest_question_list = Question.objects.order_by('-pub_date')[:5] # template = loader.get_template('polls/index.html') # context = { # 'latest_question_list': latest_question_list, # } def index(request): latest_question_list = Question.objects.order_by('pub_date')[:5] context = {'latest_question_list': latest_question_list} return render(request, 'polls/index.html', context) # render takes the request (object,template,dictionary<optional>) # def detail(request, question_id): # try: # question = Question.objects.get(pk=question_id) # except Question.DoesNotExist: # raise Http404("Question does not exist") # return render(request, 'polls/detail.html', {'question': question}) # SHORTCUT TO USE GET AND … -
Django Template Tag for Boolean Value
I'm new to Django, and I'm stuck on a template tag that I can't figure out how to get working. I know I'm missing something in my view but I have written it in several different ways and can't seem to find the right way to do this. I have a Morris chart in my app that I am trying to provide information to. I want to show the percentage of operators that are available. In my model, I have a Boolean value that says if the operator is_available. When I pass it back to the template I want the template tag to run the percentage and pass back the value to the morris pie chart. Here is my view: @login_required(login_url='login/') def operator(request): operators = Operator.objects.all() operator_status = Operator.objects.values_list('is_available', flat=True) context = { 'operators': operators, 'operators_available': operator_status, } return render(request, 'content/operator.html', context) This is the template tag in use: <div class="widget-detail-1"> <h2 class="p-t-10 m-b-0"> {{ operators_available | percentage_of:True }} </h2> </div> </div> and finally my template tag: @register.filter(name='percentage_of') def percentage_of(part, whole): try: return "%d"[2:] % (float(part) / whole * 100) except (ValueError, ZeroDivisionError): return "Division by Zero" -
