Timed Based Graph Plotting Python Django Using Firebase
I am using Django to make a dashboard to show sensor data. I am using chart.js for that I am retrieving sensor data of two days or less only. The problem is that how can I divide my graph for it.I think it might be possible using python time library or Django or something like that if so kindly suggest me some way to do it. I think that if java script can help us that will be great too. I just want data parsing based on time to plot and view it nicely. -
how to use django class model self in views.py
I want to create a filtering function and output the result value to the table. [A - models.py] class School(models.Model): .... def proceeding(self, request): from_date = request.GET.get('from_date') to_date = request.GET.get('to_date') student= Student.objects.filter(school_id=self.id) return Feedback.objects.filter( entry_date__range=[from_date, to_date], student_id__in=student).values('entry_date').distinct().count() [B- models.py] class Student(models.Model): ... school = models.ForeignKey(School, on_delete=models.CASCADE) class Confirm(models.Model): .... school = models.ForeignKey(Student, on_delete=models.CASCADE) I know why the results are not displayed. I know that the request written next to self in models.py doesn't work. However, the reason you must use it in models.py rather than views.py is that you must use self. Please answer to the seniors who know how to make a request in models.py!! -

Assign a model to another model using ModelChoiceField
I am new to Django and would like to create a platform where teachers can create student profiles and assign reports to the specific student. Therefore, I have made two models (Student & Report) and two CreateViews. When creating a report, the teacher has the option to select a student from a choice field. This I have done using ModelChoiceField. However, when submitting the report model, the students name is not saved to that model. How can I accomplish this? Ultimately I would like to have a profile to each student showing their info and reports attached to their model. models.py class Student(models.Model): author = models.ForeignKey(User, null=True, on_delete=models.CASCADE) name = models.CharField(max_length=30, default="") age = models.CharField(max_length=2, default="", blank=True) class Report(models.Model): date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, null=True, on_delete=models.CASCADE) title = models.CharField(max_length=30) forms.py class StudentForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(StudentForm, self).__init__(*args, **kwargs) class Meta: model = Student fields = ['name','age',] class ReportForm(forms.ModelForm): student = forms.ModelChoiceField(queryset=Student.name, initial=0) class Meta: model = Report fields = ['title','file','player',] views.py class StudentCreate(LoginRequiredMixin, CreateView): model = Student template_name = 'student_create.html' form_class = forms.StudentForm def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) class ReportCreate(LoginRequiredMixin, CreateView): model = Report template_name = 'report_create.html' form_class = forms.ReportForm def form_valid(self, form): form.instance.author = … -
Dynamic filter in django template
I would like to provide users possibility of filtering orders by any value, for example date, id etc. Is there any way how to do it using django feautures?

Iframe stops working after upgrading to Django 3.2 LTS
I was using Django 2.2 up till now and I recently tried upgrading to Django 3.2 We use a website live chat plugin called tawk.to which works by embedding an iframe to our page with the chat option in there. However, after upgrading to Django 3.2, even though the plugin's JS code is loading, the iframe is missing from the website altogether. I am not sure what is causing the issue. Is the iframe blocked in Django 3.2 or do I have to enable any setting for it? -
Django - reading MultiPolygons from postgres database does not return valid geometries
I'am creating web app to display some data in forms of charts, maps etc. I am using Bokeh for plotting. For maps I need to load shapefile with MultiPolygons containing regional borders. I have it loaded in my PostgreSQL database and I can display geometries from pgAdmin. I have a model for this table registered, here's the code class Polska(models.Model): gid = mdls.AutoField(primary_key=True) region = mdls.CharField(max_length=80, blank=True, null=True) geom = mdls.MultiPolygonField(srid=0, blank=True, null=True) When I'm trying to load these shapes and pack them into GeoDataFrame from geopandas I get a massive wall of text with an error (its just a snippet, basically it prints me the entire geometry) Input must be valid geometry objects: MULTIPOLYGON (((494179.5260320738 358814.2954531405, 494173.5314778397 358816.6456283908, 494178.0633204972 358822.8603784787, 494231.7738932786 358896.5675205989, 494321.7782545781 359023.6103092115, 494341.6988730072 359051.7332468079.....))) Code from loading in my views:geodf = gpd.GeoDataFrame(pd.DataFrame(Polska.objects.values("region","geom")),geometry="geom") So there is a geometry object, but for some reason it doesnt read as one. Interestingly when I try to check the type of this Multipolygon object it tells me "MULTIPOLYGON EMPTY". Can someone help me out and suggest where the problem can be? If some info is missing than let me know, I'll update asap. -
Argparse arguments in Flask application (production)
I'm trying to refactor a command line Python 3 application to an API with Flask. The application has a computer vision use case and I'm receiving an image for analysis. I'm currently using OpenCV, Python 3.8.7 I am not sure on how to refactor the arguments passes into the command line. What is the best way to bring these arguments into a production environment?

Is my approach for creating a custom user model for my Ecommerce website correct?
I am creating a Custom User Model for my Ecommerce website . There are three types types of users in my website : Buyer Seller Company employee (Note : Company employee are further classified into the following types) 3.a) Sales support 3.b) Moderation team 3.c) Analytics team 3.d) Ticket manager 3.e) Super admin So basically there are 7 different types of users in our ecommerce seller , buyer and 5 types of company users . Now , In order to achieve this , I first created a new app called "Users" in my freshly made blank Django project . Inside the Users/models.py , I created the Custom user model as follows : #Users/models.py from django.contrib.auth.models import AbstractUser from django.db import models user_type_choices = ( (1, 'buyer'), (2, 'seller'), (3, 'Sales-Support'), (4, 'Moderator-Team'), (5, 'Analytics-Team'), (6, 'Ticket-Manager'), (7, 'Super-Admin') ) class CustomUser(AbstractUser): age = models.PositiveIntegerField(null=True, blank=True) user_type = models.PositiveIntegerField(choices=user_type_choices) phone = models.PositiveBigIntegerField() After this model was created , I did the required changes to the settings.py file in the main app of the project by adding the "Users" app to the list of installed apps and adding the following line : AUTH_USER_MODEL = 'Users.CustomUser' Is my approach for creating custom user … -

How can I access my graphql endpoint with authentication implemented using graphene_django_crud?
I want my api to be accessible by only authenticated user, So, I used **views.py** class PrivateGraphQLView(LoginRequiredMixin, GraphQLView): pass **urls.py** from users.views import PrivateGraphQLView from users.views import activate_account,password_reset from graphene_django.views import GraphQLView urlpatterns = [ path('admin/', admin.site.urls), path('api/',PrivateGraphQLView.as_view(graphiql=True)), But now I am not able to login , which seems reasonable since I put my endpoints in the LoginRequiredMixin. What I thought to make two endpoints but which is also not possible. What should I do, so that it won't be accessible to unauthenticated user and also able to do the login. I also tried schema.py from graphene_django_crud.types import DjangoGrapheneCRUD from graphene_permissions.mixins import AuthNode class ItemType(AuthNode,DjangoGrapheneCRUD): permission_classes = (AllowAuthenticated,) class Meta: model = Item max_limit = 10 but then I am able to access Item query being unauthorized user -

Django: Which takes more time, a query to database or filtering the data we received?
I have a table of questions that have different type of questions (minimum 3 types). I make a query for every type of question. I'm sure this is heavy on the database and takes a lot of time.

I want to know which is recommended? and which one takes less time? -

How to access these tables more efficiently in django
we have the following data base schema to store different types of data. DataDefinition: basic information about the new data. *FieldDefinition: Every DataDefinition has some fields. Every field has a type, title, etc, that information is stored here. Every DataDefinition has more than one FieldDefinition associated. I have put '' because we have a lot of different models, one for every kind of field supported. DataValue, *FieldValues: we store the definition and the values in different models. With this setup, to retrieve a data from our database we need to do a lot of queries: Retrieve the DataDefinition. Retrieve the DataValue. Retrieve the *FieldDefinition associated to that DataDefinition. Retrieve all the *FieldValues associated to those *FieldDefinition. So, if n is the average number of fields of a DataDefinition, we need to make 2*n+2 queries to the database to retrieve a single value. We cannot change this setup, but queries are quite slow. So to speed it up I have thought the following: store a joined version of the tables. I do not know if this is possible but I cannot think of any other way. Any suggestion?

Custom django mangement command to add/amend views.py, filters.py etc
Django has the built-in command startapp which creates a new app directory and some standard files within. I was wondering whether custom management commands (or something different?) can be used to automate similar repetitive steps. For example I find myself repeating a certain set of steps when creating certain generic new homepages. To name a few: Adding a url to urlpatterns in <app>.urls.py Creating a template in <app>.templates Adding a view, subclassing django.views.generic.TemplateView to <app>.views.py Adding the template to the view Adding ViewSet to <app>.rest.py Register this ViewSet to router in <app>.urls.py Ideally I would like to create a command in the following style createNewPage --viewName <name1> --viewSetName <name2> --url <url> --api <api_url> Is something like this achievable? -

I have 2 models User and Suspension class Suspension: content_type = models.ForeignKey(ContentType, related_name='suspension', on_delete=models.CASCADE) object_id = models.CharField(max_length=255) content_object = GenericForeignKey('content_type', 'object_id') suspended = models.BooleanField(_("suspended"), default=False) reason = models.TextField(blank=True) I want to change user.is_active based on a related suspension.suspended instance. My code is: def form_valid(self, form): from userprofile.models import User as user model_name = self.get_model_name_from_url_kwargs() model = eval(model_name) suspension, created = Suspension.objects.get_or_create( content_type = ContentType.objects.get(app_label=model._meta.app_label, model=model._meta.model_name), object_id = self.kwargs['pk'], ) suspension.reason = form.cleaned_data['reason'] suspension.suspended = form.cleaned_data['suspended'] suspension.content_object.is_active = not form.cleaned_data['suspended'] suspension.save() return super().form_valid(form) I can confirm that printing suspension.content_object.is_active returns a correct result, however, it is not saved. What is wrong? -
Django Rest Framework: How to use EXCEPTION_HANDLER with DEBUG = True?
I'm using a custom exception handler for my REST API. I'd like to use my custom exception handler, which responds with JSON data that my front end knows how to handle. The problem is that with the setting DEBUG = True, Django doesn't use my custom exception handler. Instead, it responds with the standard HTML debug page, like this: Here's my settings.py: DEBUG = True REST_FRAMEWORK = { # I still get the default Django 'EXCEPTION_HANDLER': 'stripe_app.utils.custom_exception_handler' } ... I know that I could just set DEBUG = False, but if I did that I'd also have to change many other things that use the DEBUG variable. So, How can I use my custom exception handler with the DEBUG = True setting? I've already looked for answers in the DRF docs: https://www.django-rest-framework.org/api-guide/settings/#exception_handler and the Django docs: https://docs.djangoproject.com/en/3.1/ref/settings/#debug but I can't find the answer I'm looking for.
