Django: How to read question mark (?) in the django URL
I am developing a Django app that stores the user input in the database. Now the problem is that when the user writes the ? in the input field, Django treats it as the part of querystring so it doesn't save it. I am using the following JavaScript code: $("#submit").on("click",function(){ text = $("#input").val(); $.get('/add/'+text); } And here is my urls.py file: urlpatterns = [ path('add/<str:text>',views.add, name='add'), .............. ] And in views.py, I have: def add(request,text): field = Text(text=text) field.save() return HttpResponse('') -

Connecting Django and Postgres: FATAL authentication error
I'm trying to use PostgreSQL in my Django project.

How to dynamically load data in django
I've been learning django for the last couple of days and I'm trying to build a very simple app that consists on the following: models.py class Stock(models.Model): date = models.DateField() price = models.IntegerField() views.py def index(request): list_dates = Stock.objects.order_by('date').values_list('date', flat = True).distinct() my_dict = {'list_dates' : list_dates} return render(request, 'stocks/index.html', context = my_dict) index.html <body> <select name="date" id="date"> <option value="select">Select Data</option> {% for date in list_dates %} <option value="{{date}}">{{date}}</option> {% endfor %} </select> <h1>{{price here}}</h1> </body> This is a very simplified version of the final concept, which will have many more fields other than price What I want to do is: Get the date the user selected on the select tag Use it to access the django database and then only load the price that matches the selected date Insert it inside the h1 tag Refreshing this when the date is changed on the select tag What's the easiest way to do this? Thanks! -

Render a Multipage Excel File
There is a library called templated-docs that allowes render templates to different file formats. My goal is to render multipage Excel file: I have an .ods template which looks like this: Also have a list of dicts each for a page: context = [ {"number": 1}, {"number": 2}, ] Rendering of context happens here https://github.com/alexmorozov/templated-docs/blob/master/templated_docs/init.py#L128. As far as I can see context should be a dictionary. And there is no built-in way to render a multipage excel, right? Well, for now everything I could figure out is to render data dicts by one (template.render({"number": 1}), template.render({"number": 2})) and then combine them into a single entity. But I'm not sure this to be a proper way. Could you say please if there is some another ways to solve this problem? P.S. The real file have 15 pages. -
virtualenvwrapper on Mac (using terminal) : Error while finding module specification for 'virtualenvwrapper.hook_loader'
Trying to finish installing virtualenvwrapper. I have already installed Python 3.8.3 and virtualenv/virtualenvwrapper but when I am exporting to setup a virtual environment location using: export WORKON_HOME=$HOME/.virtualenvs export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 export VIRTUALENVWRAPPER_VIRTUALENV_ARGS=' -p /usr/bin/python3 ' export PROJECT_HOME=$HOME/Devel source /usr/local/bin/virtualenvwrapper.sh It says there is no directory. So I have changed my source to be /Library/Frameworks/Python.framework/Versions/3.8/bin/virtualenvwrapper.sh because after using which virtualenvwrapper.sh, that is where it is. once I have done this though i get the error virtualenvwrapper.sh: There was a problem running the initialization hooks. If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenvwrapper has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 and that PATH is set properly. What exactly do I need to change for this environment to work? -

models.DoesNotExist [...] matching query does not exist. Result is being found in the DB

Check for string in queryset within a Django template

I have a django form, but it's not showing the "upload file" field when I render it on my website. What am I doing wrong? Ideally, the form has a question ID associated with it that's submitted automatically (e.g. it doesn't have to be manually put in by the user when uploading the file) models.py class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) response_file = models.FileField(upload_to='audio_responses') forms.py class PostAudio(forms.ModelForm): class Meta: model = Choice fields = ('response_file',) views.py def QuestionRecordSubmitView(request, pk): model = Question if request.method == 'POST': form = PostAudio(request.POST, request.FILES) if form.is_valid(): form.instance.question_id = pk form.save() # get survey pk question_instance = Question.objects.get(pk=pk) survey_pk = question_instance.survey.pk return redirect('survey-share',pk=survey_pk) else: form = PostAudio() return render(request, 'survey/question_audio_submit.html') html {% extends "landing/base.html" %} {% block content %} <h2>New Submission</h2> <form method="POST" class="post-form" enctype="multipart/form-data">{% csrf_token %} {{ form.as_p }} <button type="submit" class="save btn btn-default">Save</button> </form> {% endblock content %} -
How to set default group group for users in Django Rest Framework?
I would like to automatically assign the newly registered user to the "User" group. So the group "User" should be the default group for all users. Register Serializer class RegisterSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('id', 'username', 'email', 'password', 'groups') extra_kwargs = {'password': {'write_only': True}} def create(self, validated_data): groups_data = validated_data.pop('User') user = User.objects.create_user(validated_data['username'], validated_data['email'], validated_data['password']) for group_data in groups_data: user.groups.add(group_data) return user Register API # Register API class RegisterAPI(generics.GenericAPIView): serializer_class = RegisterSerializer def post(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) user = serializer.save() return Response({ "user": UserSerializer(user, context=self.get_serializer_context()).data, "token": AuthToken.objects.create(user) [1] }) When i run the code i get an error: Bad Request: /api/auth/register. I can not really trace back where my mistake is? Im happy for any clarification. -

How do I resolve a non-interactive object in Django
