Django How to get a queryset from another queryset in a template
I want to filter a queryset that depends on another queryset that already depends on another queryset My models.py class Escola(models.Model): id = models.AutoField(db_column='ID', primary_key=True) nome = models.CharField(db_column='Nome', max_length=255, blank=True, null=True) class Inscrio(models.Model): id = models.AutoField(db_column='ID', primary_key=True) escolaid = models.ForeignKey(Escola, models.DO_NOTHING, db_column='EscolaID', blank=True, null=True) class Utilizador(AbstractBaseUser) id = models.AutoField(db_column='ID', primary_key=True) inscriçãoid = models.ForeignKey(Inscrio, models.DO_NOTHING, db_column='InscriçãoID', blank=True, null=True) email = models.CharField(db_column='Email', max_length=255, blank=True, null=True, unique=True) nome = models.CharField(db_column='Nome', max_length=255, blank=True, null=True) password = models.CharField(db_column='Password', max_length=500, default='pass'); USERNAME_FIELD = 'email' EMAIL_FIELD = 'email' My views.py def view_forms(request): return render(request, "main/view_forms.html", {"escolas": Escola.objects.all(), }) I am doing {% for escola in escolas %} {% for inscrio in escola.inscrio_set.all %} {% for utilizador in inscrio.utilizador_set.all %} <tr> <td><center>{{inscrio.id}}</center></td> <td><center>{{escola.nome}}</center></td> <td><center>{{utilizador.id}}</center></td> {% endfor %} {% endfor %} {% endfor %} I am currently trying to get the Inscrio data from Escola.

Configure SSL (HTTPS) for my Django (Elastic Beanstalk) Backend API
I've been struggling the past week learning AWS to deploy my React - Django application to AWS. My react stack is successfully deployed to AWS Amplify, took no time at all. After deploying my Django stack to Elastic Beanstalk, I've stumbled on the following error: xhr.js:178 Mixed Content: The page at 'https://amplify.url' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://api.elasticbeanstalk.com/'. This request has been blocked; the content must be served over HTTPS. My question is, how do I configure https to my django eb application? I purchased a domain for my front-end, but do I also have to purchase a domain for my back-end api, or do I use a subdomain? I'm having trouble finding instructions for the best practices, and how to implement them. If anyone can give me advice for configuring my elastic beanstalk load balancer, that would be great, thanks so much! -
How to save multiple videos and images in Django Rest Framework?

Django Nested inline formset-- nested form does not save to DB, no errors thrown
We have a few nested inline formsets in an application. Ideally, the goal is to allow for dynamic and unlimited population of these fields so that users can add an arbitrary number of notes. The form renders, the JS calls are populating; however, I am not seeing the update on the nested from manager. This is my first Django project and I am not finding anything regarding what is causing the hang up. The Organization is saved in the DB, but the notes are not. Thanks in advance for any help Model.py: class Organization(models.Model): //irrelevant organization information// class OrganizationNote(AbstractNotes): note = models.TextField(blank=True) org = models.ForeignKey(Organization, on_delete=models.CASCADE,blank=True, null=True) modelforms.py: class OrganizationForm(AbstractBigThree): class Meta: model = custModels.Organization fields = '__all__' orgNoteFormSet = inlineformset_factory(custModels.Organization, custModels.OrganizationNote, form=OrganizationForm, extra=0) ModelView.py class OrganizationCreateView(CreateView, AbstractOrganizationView): def get(self, request, *args, **kwargs): self.object = None form_class = self.get_form_class() form = self.get_form(form_class) org_note_form = orgNoteFormSet() return self.render_to_response( self.get_context_data(form=form, org_note_form=org_note_form)) def get_context_data(self, **kwargs): data = super(OrganizationCreateView, self).get_context_data(**kwargs) if self.request.POST: data['notes'] = orgNoteFormSet(self.request.POST) else: data['notes'] = orgNoteFormSet() return data def form_valid(self, form): context = self.get_context_data() notes = context['notes'] with transaction.atomic(): self.object = form.save() if notes.is_valid(): notes.instance = self.object notes.save() return super(OrganizationCreateView, self).form_valid(form) def get_success_url(self): return '/portal' template: {% extends 'base.html' %} {% … -
Custom backend authenticate success without returning User object
I'm writing a backend to validate users based on tokens from AWS Cognito. Is it possible to write an authenticate() method for a backend that "succeeds" without returning a Django User object? For example: class CustomBackend(BaseBackend): def authenticate(self, request, username=None, password=None): if token_is_valid(request.COOKIES["nz_auth_jwt"]): # Success, let the user through else: # Failure, redirect to login page to get token from Cognito My understanding of "authenticate()" is that "success" is denoted by returning a User object, and failure by returning None. Can this work or do we need to make User objects based on the tokens so we have a User to return? -
Apply an AND filter on search results with Django
I have a django application where I maintain a list of products. Each product has a number of "categorizations" attached to it. I want to search the table of product and apply filters to that search, so that with each added filter, there are less and less products returned. The categorizations have a relationship to product. They way they are attached to products is a bit complicated, but here is the gist of it: class ProductCategorization(Categorization): """ A categorization value selected for a specific `Product` """ value = models.ForeignKey(ProductCategorizationValue, related_name="categorizations", on_delete=models.PROTECT) product = models.ForeignKey(Product, related_name="categorizations", on_delete=models.CASCADE) class ProductCategorizationValue(CategorizationValue): value = models.CharField(max_length=100) So you could imagine that you would search for all products that have a categorization with value "SHOES" as follows: Product.objects.filter(Q(categorizations__value__value="SHOES")) Now this is all fine. However, now I want to apply a second filter, so that I only get a list of products that are SHOES and BLACK. I have tried variations of the following but I keep getting an empty list instead of relevant products: Product.objects.filter(Q(categorizations__value__value="SHOES") & Q(categorizations__value__value="BLUE")) I know there is something strange going on behind the scenes when the SQL query is built, I just can't figure out how to structure my Django code. -

Returning a function from a separate python file in django
I have a project that just creates a plot. The code to generates this plot is stored in theplot.py from a function called theplotfunction. What i am trying to do is to show this plot to the user by pressing a HTML button in my index.html but it is not loading. I have my theplot.py to create the plot: THEPLOT.PY: def theplotfunction(request): import matplotlib.pyplot as plt import numpy as np import io from django.shortcuts import render plt.plot(range(10)) fig = plt.gcf() buf = io.BytesIO() fig.savefig(buf,format='png') buf.seek(0) string = base64.b64encode(buf.read()) uri = urllib.parse.quote(string) return render(request, 'plot.html',{'data':uri}) I then link my url to go to a function in views.py. URLS.PY: path('plot', views.plot, name='plot'), Then the views.py plot function will go to the theplot.py to run the code to generate the plot. VIEWS.PY: `from .theplot import theplotfunction` def plot(request): return (theplotfunction) My index.html shows the connection to views function to be run INDEX.HTML: <input type="button" value="plot" onclick="window.open('plot')"> finally the plot.html is shown to the user and the graph is seen PLOT.HTML: <img src="data:image/png;base64,{{ data }}" alt="" height="250" ,width="250"> my problem is the I click the button to generate the plot i get a function' object has no attribute 'get' error.

Do Django Template Processors Mess with URLs?
In Django, I am trying to render a url to a template. However, this url is rendered differently depending on how it is called. In the view: url = request.build_absolute_uri() print(url) # returns http://127.0.0.1:8000/path/ raise Exception(url) # returns //localhost:8000/path/ print(url[0]) # returns h raise Exception(url[0]) # returns h In the template: {{ url }} <!-- returns //localhost:8000/path/ --> I feel like I am going crazy here. Do Django's template context processors contain a regular expression that specifically checks for urls and messes with them? -

Django: How to fix 'The QuerySet value for an exact lookup must be limited to one result using slicing.' error
I am attempting to make a simple query where I grab all "STATION_ROLE" objects with parameters Active and Deleated equal to True and False respectively. In doing so I trigger an error: "The QuerySet value for an exact lookup must be limited to one result using slicing." #Query station_roles = STATION_ROLE.objects.filter(Active__exact=True,Deleated__exact=False) #Model class STATION_ROLE(models.Model): S_ID = models.ForeignKey(STATION, null=True, verbose_name="Ground Station", on_delete=models.CASCADE) Type = models.IntegerField(blank=True, null=True, verbose_name="Role Type") Settings = models.TextField(max_length=100000, blank=True, null=True, verbose_name="Role Settings") Active = models.BooleanField(default=False, verbose_name="Active Flag") #Task Turned on Deleated = models.BooleanField(default=False, verbose_name="Deletion Flag") #Task is compleated or user deleated DeleatedBy = models.ForeignKey(User, blank=True, null=True, verbose_name="Deleted By", on_delete=models.CASCADE) Others have asked this question but under different circumstances. In one I saw, someone passed in a queryset into one of the filter parameters. I understand the error that case, as a queryset wouldn't make sense for a filter parameter in an exact lookup. In this case I am not passing any queryset. Another answer has them slice the result as follows: station_roles = STATION_ROLE.objects.filter(Active__exact=True,Deleated__exact=False)[0] While this eliminates my error, I do not want to limit the results of this query to one result. I want station_roles to be comprised of multiple STATION_ROLEs Why does Django want me to … -

Django combining form entries by datetime
I've created a django project to track medications at work. Using modelformset factory, I've created a form that allows the user to document the amount of each medication on the same form. For example, Drug 1, Drug 2, and Drug 3 are all listed on the same form and the user needs to enter the total amount of mg for each drug. When submitted, the entry creates a separate database record for each drug with the same datetime. I have created a query page that lists all the entries. I would like for the query to combine all the entries that share the same datetime, but I cannot figure this out. Does anyone have any suggestions? Thanks so much. -
