Django filter based on start date and end date for single day
I have a query start_date = '2019-11-17' end_date = '2019-11-18' events = Event.objects.filter(start_date__gte=start_date,end_date__lte=end_date) This doesn't return any result.. I tried direct mysql query, even this doesn't return any results, SELECT * FROM `events` where start_date >= '2019-11-17' and end_date <= '2019-11-18' Any idea where I am wrong? In my database I have these 3 rows, -

Slow Django Page - Doesn't Appear to be caused by SQL
I'm trying to debug a slow Django listview page. The page currently displays all tests (133), as well as the latest result for each test. There are approximately 60,000 results, each result having a FK relationship to a single test. I've optimized the SQL (I think) by selecting the latest result for each test, and passing it in as a prefetch related to my tests query. Django Debug Toolbar shows that the SQL is taking ~350ms, but the page load is ~3.5s. If I restrict the list view to a single test though, the SQL is ~7.5ms, and page load is ~100ms. I'm not fetching anything from S3 etc, and not rendering any images or the like. So my question is, what could be causing the slowness? It seems like it is the SQL, since as the result set grows so does page load, but maybe rendering of each item or something similar? Any guidance on what to look into next would be appreciated. -
return render(request, "index.html", {'index': "<div> dfdafadfasdsad </div>"})
I'm trying to append some html onto my index.html template from a view in django.

Django 2 multi model update view
I'm having a really hard time trying to get an update view class to work. I'm trying to make a cooking recipe app. I found an example of a createview that handles multiple models. im trying to write an update view, but. When ive plugged in my url, the page renders blank with no records. I think the problem is withthe context data, but my experiance with djagno is very limited. my class is below class RecipeUpdateView(UpdateView): model = Recipe form_class = RecipeForm success_url = '/recipe/' def get(self, request, *args, **kwargs): self.object = None form_class = self.get_form_class() form = self.get_form(form_class) ingredient_form = IngredientFormSet() instruction_form = InstructionFormSet() return self.render_to_response( self.get_context_data(form=form, ingredient_form=ingredient_form, instruction_form=instruction_form)) def post(self, request, *args, **kwargs): self.object = None form_class = self.get_form_class() form = self.get_form(form_class) ingredient_form = IngredientFormSet(self.request.POST) instruction_form = InstructionFormSet(self.request.POST) if (form.is_valid() and ingredient_form.is_valid() and instruction_form.is_valid()): return self.form_valid(form, ingredient_form, instruction_form) else: return self.form_invalid(form, ingredient_form, instruction_form) def form_valid(self, form, ingredient_form, instruction_form): self.object = form.save() ingredient_form.instance = self.object ingredient_form.save() instruction_form.instance = self.object instruction_form.save() return HttpResponseRedirect(self.get_success_url()) def form_invalid(self, form, ingredient_form, instruction_form): return self.render_to_response( self.get_context_data(form=form, ingredient_form=ingredient_form, instruction_form=instruction_form)) Can any one help me out with this?

How to properly filter or exclude based on a parameter in Django?
I can do this in Django: query = {field_name: value} if include: return queryset.filter(**query) else: return queryset.exclude(**query) That's bad because there's a fair bit of duplication, and it's rather verbose. I can also do this, which is much simpler: return queryset._filter_or_exclude(not include, field_name=value) But that's also bad, because I'm calling a protected method. Is there a way to combine the best of both? return queryset.filter(exclude=not include, field_name=value) is not a thing. -
How do I get a specific value from an object through foreign key connection in django?
guys! I got the following table and want to get all scad files from objects of Model3D where part of is not null and has the same id as Model3D. Model3D is an 3D printer object that may consists of more than just one part and has therefore the "part of" attribute that holds the id of the original model. class Model3D(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=300) description = models.CharField(max_length=500) original_Model = models.ForeignKey('Model3D', on_delete=models.CASCADE, null=True) creation_Date = models.DateTimeField(auto_now=True) stl_File = models.FileField(null=True, upload_to='models/stlFiles') scad_File = models.FileField(null=True, upload_to='models/scadFiles') parameter_id = models.ForeignKey('Parameter', on_delete=models.CASCADE, null=True) part_of = models.ForeignKey('Model3D', related_name="part_of_model3d", on_delete=models.CASCADE, null=True) I tried the following: part_models_scad_files = Model3D.objects.filter(part_of__isnull=False).select_related(id=self.id) but how do i get the scad files and not only the objects? Thanks for your help, I really want to learn more! -

VS Code: Python Interpreter can't find my venv
I've been stuck on this for a few days, kindly help me if you can. I have my venv folder on my root project folder. When I try to set the Python Interpreter, it shows me only the Python installed in my machine and not the one in my root folder. It was working fine until I formatted my PC and installed windows 10 64 bits. (was running on windows 7 64 bits prior) Things I have tried: Set the path manually via pythonPath and/or venvPath, in both workspace and user settings: "python.pythonPath": "F:/Web Dev/Python/Django/project_x_v2/backend/venv/Scripts/python.exe", "python.venvPath": "F:/Web Dev/Python/Django/project_x_v2/backend/venv/Scripts/python.exe", It shows me the correct location in the placeholder but I don't have the option to choose it from the dropdown list: Any ideas how I can solve this? Thank you very much. -
Confused with multiple dimension dictionaries
I got this method which returns a multi-dimensional dictionary. def get_apps(): menu_one = { 'name': 'Apps group one', 'menu_one_app_one': { 'name': 'app one!', 'icon': 'fa-rocket', 'url': '/Url' }, 'menu_one_app_two': { 'name': 'app two!', 'icon': 'fa-user', 'url': '/Url2' } }, menu_two = { 'name': 'Apps group two', 'menu_two_app_one': { 'name': 'app three!', 'icon': 'fa-clipboard', 'url': '/Url3' }, 'menu_two_app_two': { 'name': 'app four!', 'icon': 'fa-users', 'url': '/Url4' } } return menu_one, menu_two So in my Django view I'm calling the method get_apps() in order to get the apps with their attributes and show them on different groups like this: def my_django_view(request): apps = get_apps() return render(request, "apps.html", {'apps': apps}) And the idea is to display them by group in my template like this: {% for menu in apps %} <!-- this is ok! --> <div class="breadcrumb"> <h1>{{ menu.name }}</h1> {% for app in menu %} <!-- here is the part where I am wrong --> <a href="{{ app.url }}" data-toggle="tooltip" title="{{ app.name }}"> <i class="fa {{ app.icon }}></i> </a> {% endfor %} </div> {% endfor %} I know what is wrong thanks to django since it's saying 'str' has no attr 'name', of course, since it is a dictionary.

<a> tag is not clickable and not linked
Okay , I am not sure if that is a problem with my Django project logic or with my html tags , so here it goes I am trying to make a link that lists all the groups created by a specific user the template code <h1> <a href"{% url 'infrastructure:user-orgs-view' slug=request.user.slug%}"> Your Organizations </a> </h1> url.py part path('accounts/<slug>/orgs', views.UserOrgsView, name='user-orgs-view' ) my view def UserOrgsView(request, slug): orgs = Profile.objects.get(slug=slug).organization_set return render(request, 'user_orgs.html', { 'orgs' : orgs}) the only css I am using on this page body { text-align: center; vertical-align: middle; } p *{ vertical-align: middle; } what happens is the tag appears as normal text , not clickable .. not linked .. nothing .. any idea why is that happening ? -
How do I auto increment field that is part of unique_together in Django admin
Basketball Game has 4 Quarters. I would like Django to auto increment Quarter.number for each Game in Admin, so I don't have to always correct them manually. Example models.py class Game(models.Model): name = models.CharField() class Quarter(models.Model): number = models.IntegerField(help_text='quarter number from 1 to 4') game = models.ForeignKey(Game) class Meta: unique_together = ['game', 'number'] So number in Quarter can be 1, 2, 3 or 4 (or more for other sports) and should be set to 1 by default. After saving first quarter for one Game it should suggest number=2 for the next entry of the same Game. The incremented numbers should also get shown correctly in admin.TabularInline if I set Quarter as inline of Game in admin.py (in below code Django would by default show 3 entries for a new Game, but all would have default number=1): class QuarterInline(admin.TabularInline): model = Quarter class Game(admin.ModelAdmin): inlines = [QuarterInline] How can I achieve that number gets incremented by default for each game? -
Is there a way for Django to accept naive datetimes with USE_TZ=True, or to suppress warnings?
Our company has been a long-time user of Django -- for more than 10 years. We are currently running Django 1.11.26. We've dealt with a lot of datetime-related issues over the years, but our current issue is proving challenging. Our goal is to do the following: use Django's timezone support (setting USE_TZ=True) with UTC as default time zone for a couple of denormalized fields (daily rollups of energy data) store naive datetimes As is documented in many Stack Overflow questions, Django will issue a warning with datetime field values set to a naive datetime: RuntimeWarning: DateTimeField received a naive datetime...while time zone support is active. We think our use case for storing naive datetime is a reasonable one. While for almost all our datetime fields it make sense to use UTC, for certain kinds of daily rollups we want to store a naive/agnostic datetime indicating the start datetime of the day in the local time zone (multiple time zones for different objects). By using a naive datetime, we are able to use datetime-related filters. Therefore if we are summarizing certain kinds of energy rollups for a given datetime, we can find the rollup for the same local datetime for buildings … -
Use DeleteView to delete an object, got "'mysite' is not a registered namespace"

Django Rest Framework get_field is not being called
I've got an existing Django code base which uses Django Rest Framework to expose the data. I had one field which was defined as a SerializerMethodField() in the Serializer: categories = serializers.SerializerMethodField() And in the same serializer this get_method is defined: def get_categories(self, obj): return [obj.categories.choices[key.upper()] for key in obj.categories] That worked, but I had to add a way to also let users post new data to the api. Since the SerializerMethodField is read-only by definition I changed the field to a CharField (because it's a varchar in the DB): categories = serializers.CharField(required=True, allow_blank=False, max_length=100) That works for posting new content, but unfortunately, the get_categories() is not being called anymore. Does anybody know how I can make it call the get_categories() method while keeping the CharField? -
Django Show Unique List Of Subjects (Many To Many) In Dropdown Menu
I want to be able to produce a dropdown menu in my template with a unique list of subjects. Subjects are populated inside of admin rather than hard coding them in SUBJECT_CHOICES. A course can have many subjects or only 1 subject. For example: Course Title = Django Subject = Technology Course Title = Python Subject = Technology Course Title = Accounting Subject = Business Course Title = E-commerce Subject(s) = Technology, Business CourseListView corresponds to the course_list.html template. Models and views: https://dpaste.de/s8jq Desired Output: https://imgur.com/a/l0FWJoN I tried writing a for loop in my template that does return the subjects successfully but they are not unique or showing only once. https://dpaste.de/NHdF I would prefer to do it with a for loop that produces unique results, but maybe it can be done with django-select2 or use a form with model select or multiple model select? Can someone provide some code for either the loop or one of these methods? I would appreciate any help with this. -

Best stack for uploading and processing several pdf files on a website?
I'm making a website where users can upload several pdf files (normally 10 MB in total, but can it can go up to 80-100 MB) and extract certain parts of those files in an Excel sheet. It involves heavy use of functions on each page, as there are a lot data to retrieve. I've already coded it in python as a script, but I want to make it as a website. Noob question: What stack should I use? Is it better using server-side or client-side? I know pdf.js can retrieve some information, but I'm not sure it would be the most appropriate for this. I was thinking about flask or django as it's already in python. What would be the best option for speed? User would use the browser, not the smartphone for this app. -
Django documenation page
I'm busy making a documentation page in my Django project and would like to make a dynamic page where theres a sidenav with links but if you click on a nav item it loads the page within the "master page aka the documentation page" without leaving that page like so https://www.nbinteract.com/tutorial/tutorial_github_setup.html I have created the side nav etc and it's working fine and linked my first URL to a nav item but if you click on the nav item, it opens that .html file instead of loading it within the main documentation page. I would like to find a way to do it with Django only and not JavaScript if possible, any guidance would be appreciated. Yes, this could be a silly question but please don't flame me about learning how to do stuff :) -
Django Rest Framework - GenericViewSet with Authentication/Permission decorator
Currently i have a simple rest setup for a single entity, you can create an object and you can retrieve it by the id. "POST" requires authentication/permission, "RETRIEVE" requires no authentication/permission. settings.py (requires global authentication/permission from every resource): REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'api.authentication.token_authentication.TokenAuthentication' ], 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.IsAuthenticated' ] } In my resource the global authentication/permission settings are applied correctly but i want to generate an exception for the retrieve method: my-resource.py: from django.utils.translation import gettext_lazy as _ from rest_framework import mixins, serializers, viewsets from rest_framework.decorators import authentication_classes, permission_classes from api.models import Entity class EntitySerializer(serializers.ModelSerializer): class Meta: model = Entity fields = [...] read_only_fields = [...] class EntityViewSet( mixins.CreateModelMixin, mixins.RetrieveModelMixin, viewsets.GenericViewSet ): queryset = Entity.objects.all() serializer_class = EntitySerializer @permission_classes([]) # this is ignored ? @authentication_classes([]) # this is ignored too ? def retrieve(self, request, *args, **kwargs): return super().retrieve(request, *args, **kwargs) Result: "POST" works as expected "RETRIEVE" return 403 ??? Why does the retrieve method still require authentication and returns 403? Is there any easier way to accomplish this? Greetings and thanks! -
