Filtering out a message for a single user
Inbox = Messages.objects.filter(Q(sender=request.user)&Q(senderDeleted=False) | Q(receiver=request.user)&Q(receiverDeleted=False)).order_by("-time", "read") context['Inbox'] = Inbox unreadMessagesCount = Messages.objects.filter(Q(receiver=request.user) & Q(read=False)&Q(receiverDeleted=False)).count() context['unreadMessagesCount'] = unreadMessagesCount I am trying to filter out messages by who doesn't want them to be seen anymore. The logic goes if senderDeleted or receiverDeleted is True then don't let the messages appear anymore. Currently the messages stay on the page unless they both click delete or the message sender being deleted is the current user logged in. What I'd like for it to do is remove it from the view of a single user and allow the other user to still view it. When clicking on the elements it does switch the fields to the True value as well. @login_required @require_http_methods(["POST"]) def delete(request,messageID): #Only remove the message if both people want it removed or if the send and receiver are the same person data_to_be_deleted = Messages.objects.get(id = messageID) if data_to_be_deleted.sender == data_to_be_deleted.receiver: data_to_be_deleted.delete() return redirect('messagesInbox') else: if data_to_be_deleted.sender==request.user: data_to_be_deleted.senderDeleted=True data_to_be_deleted.save() else: data_to_be_deleted.receiverDeleted=True data_to_be_deleted.save() data_to_be_deleted = Messages.objects.get(id = messageID) if data_to_be_deleted.senderDeleted and data_to_be_deleted.receiverDeleted: data_to_be_deleted.delete() return redirect('messagesInbox') models.py: class Messages(models.Model): sender = models.ForeignKey(Profile,related_name='sender',on_delete=models.CASCADE) senderDeleted = models.BooleanField(default=False) receiver = models.ForeignKey(Profile,related_name='receiver',on_delete=models.CASCADE) receiverDeleted = models.BooleanField(default=False) subject = models.CharField(default='',max_length=100) text = models.CharField(default='',max_length=4096) time = models.DateTimeField(auto_now_add=True) read = models.BooleanField(default=False) parent = … -
How do you setup your .venv environment?
I have a few basic questions regarding Virtualenv. I can install it, I can run it, activate it, all of this is good. My question is "And then what ?" How do setup your dev env ? -Do you create a new .venv for each project ? -And within that each project having its specific modules ? -Modules which are not used (for any reason, try a few, keep one, for instance) how are they removed ? -Going this way, once your project is finished and delivered, or dropped for any reason, how do you uninstall its .venv ? I did read the docs, it's mainly about installation, examples, coding and so on. What I can't figure is a proper usage of this tool. Thanks in advance for your help -
How to use jQuery to make a Django Alert appear (sliding down)
The following script is working fine to fade out my Django alert: <script> $(document).ready(function(){ window.setTimeout(function() { $(".alert").fadeTo(500, 0).slideUp(500, function(){ $(this).remove(); }); }, 2000); }); </script> But the following is not working---I'm just trying to do the opposite here: make the Django alert appear by sliding down.

Django web page shows error when running server
I have just started a Django project and spun up a web server. I have made minimal changes which I will post below.

Logging in django is not outputting anything
I was having issues with print statements and Django and I saw on here that its better to do logging. I am not sure what I am doing wrong though. It logs sometimes to console and other times it doesn't for the same page and I cant get it to log anything in my post method. I have tried doing the ```logger = logging.getLogger("mylogger") above all the class views, ive tried adding that line to each individual method and ive tried only having it in 1 at a time. Any thoughts?

How do I make my urlpatterns smarter, to avoid cumbersome code in my templates?
Right now I have defined my URLs such that they can include different combinations of category (always on), attribute_slugs (1 and/or 2) and brand_slug, all using the urlpatterns defined below. In my views.py file I make sure that each slug exists in the respective model, or else a 404 is thrown. I also make sure that the attributes have a specific ordering, so that I avoid identical pages where the attributes are just switched around in the URLs. Then the context is sent to a template. In my template for the categories, I implement an ecommerce filter based on the context. For example, the filter can show links to the attributes contained by the products on that particular page. So if you are on the page: /shoes/, then the color filter has the options: /shoes/green, /shoes/blue/, /shoes/black/ etc. This filter is made with the default { % url % } template tag with parameters based on the context. It works fine, but there is one issue. It is based on a lot of logical statements in the template, which is cumbersome. For example, there is an if-statement to check if there is 0 attribute, 1 attribute and 2 attributes on … -
Extend user to have many medications
I would like to save many medications to the Profile like so. models.py class Profile(AbstractUser): class Medications(models.Model): user = models.ForeignKey(Profile,related_name='user',on_delete=models.CASCADE) name = models.CharField(default='',max_length=100) amount = models.IntegerField() per_time = models.IntegerField() time_choices = (('other', 'Other'),('Post meal', 'Post meal'),('Breakfast' ,'Breakfast')) choice = models.CharField(max_length=10, choices=time_choices,default='others') forms.py class MedicationForm(forms.ModelForm): name = forms.CharField(max_length=100, required=True, help_text='Required.') amount = forms.IntegerField( required=True, help_text='Required.') class Meta: model = Medications fields = ('name','amount','per_time','choice') Now in here I would like to create a Medication with the request user.

Set up connection to VPN on Amazon Lightsail app
I've got an server on AWS using Lightsail that uses Linux/Django OS/app combination. I need to use the Django framework to create a function that will take requests coming into the server, and forward them on to another API. This API is only accessible through a VPN. I believe that by just connecting my OS to the VPN any requests my Django app sends should go through the VPN (in theory, please correct me if I'm wrong), however I am unsure how to connect to the VPN using just the Linux command line. I have the server name, a username and password, which I can connect to fine on my Windows machine by just adding a VPN connection. Is anyone able to advise if it is possible to connect this OS provided by Amazon Lightsail to a VPN, and if so how to do so in order for me to able to route HTTPS requests to the API behind a VPN! Thanks, hopefully I'm posting this in the right place! -

Using related_name in Django

How can I make packages installed using Poetry accessible in Docker?

Django isn't evaluating template variables

Chromedriver not opening Django development server

Currently its sending all values except PK. class UserByState(View): page_limit = 100 def get_paginated_context(self, queryset, page, limit): if not page: page = 1 if limit: self.page_limit = limit paginator = Paginator(queryset, self.page_limit) page_obj = paginator.get_page(page) serialized_page = serialize("json", page_obj.object_list) serialized_page = [obj["fields"] for obj in json.loads(serialized_page)] return { "data": serialized_page, "pagination": { "page": page, "limit": limit, "has_next": page_obj.has_next(), "has_prev": page_obj.has_previous(), "total": queryset.count() } } def get(self, request, *args, **kwargs): user = self.request.user page = request.GET.get('page') limit = request.GET.get('limit') state = request.GET.get('state') queryset = User.objects.all() if state and state != "all": queryset = queryset.filter(state=state) to_return = self.get_paginated_context(queryset, page, limit) return JsonResponse(to_return, status = 200) -
Not getting correct output in django filter
I have following models. class Stocks(models.Model): ticker = models.CharField(max_length=30, primary_key=True, unique=True) company_name = models.CharField(max_length=100, blank=True, null=True) ... class Advice(models.Model): ticker = models.ForeignKey(Stocks, db_column='ticker', related_name='advices', on_delete=models.CASCADE) advice_date = models.DateField(blank=True, null=True) ... class Recommendation(models.Model): ticker = models.ForeignKey(Stocks, db_column='ticker', related_name='recommendation', on_delete=models.CASCADE) target = models.FloatField(blank=True, null=True) I want to fetch details where Advice.advice_date is latest. but following code gives me all records from advice reco = Recommendation.objects.all().values('ticker__advices__advice_date').filter(ticker__advices__advice_date=datetime.date(2022,1,19)) print(reco) this is what I get: <QuerySet [{'ticker__advices__advice_date': datetime.date(2022, 1, 10)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 11)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 12)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 13)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 14)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 17)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 18)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 19)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 10)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 11)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 12)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 13)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 14)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 17)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 18)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 19)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 10)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 11)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 12)}, {'ticker__advices__advice_date': datetime.date(2022, 1, 13)}, '...(remaining elements truncated)...']> this is what I need: <QuerySet [{'ticker__advices__advice_date': datetime.date(2022, 1, 19)}] -
Django FileField upload_to custom function error
