Storing and accessing nested JSON in a Django Database
I'm using Django to store some information about a DAW and Software Synth set up. I've managed to get the database to work for storing very simple non-nested data like this: {"name": "Drums", "arm": 0, "solo": 1, "mute": 1, "devices": "compressor, reverb"}, But I have a bunch of data that's formatted something like this, which I need to be able to store and access: {"Config": { "Tracks": [ {"name": "Drums", "arm": 0, "solo": 1, "mute": 1, "devices": ["compressor", "reverb"]}, {"name": "Bass", "arm": 0, "solo": 1, "mute": 1, "devices": ["compressor", "reverb"]} ], "SelectedTrack": 0, "ActiveView": "Session" } I need to be able to update and access specific pieces of information from this, for example I need to be able to get to the names of every track easily. Or the SelectedTrack, whose number represents the index of the track. Or update the "arm" of a single track. Is there a better way of storing this? The order of the tracks is really important too as it reflects the index position of the tracks in the DAW, if they change, I need this to be reflected in the database so that I can find the index position of track named "drums" or … -
Using Boolean in Django Custom Query Set
Lately I had came to one strange thing when I was working with Django custom querysets. So, I am using request.GET for passing boolean value to my django view. Then I pass this value to my custom queryset function. It seems weird because it works in case of basic query but not with '__isnull'. Are there any differencies? views.py if request.GET.get('available'): items = Item.objects.is_available(request.GET.get('available')) # this works ... if request.GET.get('order'): transfers = Transfer.objects.not_working_is_order(request.GET.get('order')) # not working managers.py class ItemQuerySet(QuerySet): def is_available(self, is_available): return self.filter(is_available=is_available) # this works class TransferQuerySet(QuerySet): def is_order(self, bool): if bool == 'False': return self.filter(order__isnull=False) elif bool == 'True': return self.filter(order__isnull=True) # this works def not_working_is_order(self, bool): return self.filter(order__isnull=bool) # not working mytemplate.html <a href="?available=False&pg={{ request.GET.pg }}&search={{ request.GET.search }}">Not available</a> myothertemplate.html <a href="?order=True&pg={{ request.GET.pg }}&search={{ request.GET.search }}">Not order</a> -

Django: variable as initial value for form field; and filtering a form field's queryset?
I'm trying to create a form with a variable as an initial value for a form field, and to filter a MultipleChoiceField in the same model by that variable. I'm using very minimal ModelForms and Create/UpdateViews. models.py class BigLocation(models.Model): name = models.CharField(max_length=255) [...] class SmallLocation(models.Model): name = models.CharField(max_length=255) in_big_location = models.ForeignKey(BigLocation, [...]) exit_points = models.ManyToManyField('SmallLocation', [...]) From my BigLocation page, I can open a link to a SmallLocation form. In that form, I would like the value of 'in_big_location' to automatically be assigned to the BigLocation instance from which I opened the form. And also I would the 'exit_points' field to display only the SmallLocations that are in that BigLocation. I can't seem to wrap my head around how to go about doing that. Can anyone point me in the right direction? Thanks. -

Django infinite loop request is not blocking other requests
I have created a django project, and then i created two request handlers, where one completes instantly, and the other is executing an infinite loop. class IndexView(View): def get(self, request): return HttpResponse('Hello, World!') class LoopView(View): def get(self,request): while True: pass return HttpResponse() First, I make a loop request, expecting it to block incoming index requests. However, the index requests are not blocked by the loop request. Why is that happening? -
Django ORM confusion

How to control the number of objects in a Django model
I have the following model: # Product Photos class Photo(models.Model): title = models.CharField(max_length=255, blank=True) product = models.ForeignKey("Product", null=False, default="0", on_delete=models.CASCADE, related_name='photos') file = ProcessedImageField(upload_to=get_upload_path, max_length=500, null=True, blank=True, processors=[ResizeToFill(800, 450)], options={'quality': 80}) #height_field = models.IntegerField(default=0, null=True) #width_field = models.IntegerField(default=0, null=True) uploaded_at = models.DateTimeField(auto_now_add=True) As you can see there is a product foreign key.

Django WSGI script only handles root URL, Apache throws 44 for deeper URLs
The tutorials, guides and even other posts here on SO dealing with how to deploy Django on Apache seem to assume that by default when using the WSGIScriptAlias directive all deep links under that alias are handled by the script as well (usually demonstrated by visiting the /admin page). For me that seems not to be the case. Requests to the root at api.mydomain.com/v1/ are handled by my Django app, but api.mydomain.com/v1/users/ (with or without trailing slash) generate Apache's 404 "Not Found. The requested URL was not found on this server." message. Is there a setting I've missed somewhere that handles these deep links? For example for SPA's I'm used to having to redirect all requests to a front controller. Here's my Apache configuration: <VirtualHost *:80> ServerName api.mydomain.com ErrorLog /var/www/api.mydomain.com/log/error.log CustomLog /var/www/api.mydomain.com/log/requests.log combined RewriteEngine on RewriteCond %{SERVER_NAME} =api.mydomain.com RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent] </VirtualHost> <VirtualHost *:443> ServerName api.mydomain.com RedirectMatch ^/$ https://api.mydomain.com/v1/ WSGIPassAuthorization On WSGIScriptAlias /v1/ /var/www/django_app/django_app/wsgi.py ErrorLog /var/www/api.mydomain.com/log/error.log CustomLog /var/www/api.mydomain.com/log/requests.log combined SSLCertificateFile /etc/letsencrypt/live/api.mydomain.com/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/api.mydomain.com/privkey.pem Include /etc/letsencrypt/options-ssl-apache.conf </VirtualHost> -

How to serve a temporary file (non-static) via HTTP request?
I have a Python REST server, that is able to download and write a temporary file using Python TempFile. That is, at request time I have a a file in the filesystem of the server, but it is not permanent so the client cannot access it statically (I.e. via http://myserver/path-to-my-file ). I need a way to access an endpoint, and then get a file returned based on the request. (I.e. http://myserver/myendpoint/myrequestparameters) How does that work over HTTP? Is it possible? (For context, right now I am serving the file encoded as string using base64 encoding and utf-8 decoding, but my frontend application needs a direct download link) -
Django adds route address when looking for static files
Im trying to do a blog. My project has 2 urlpatterns [ path('', views.main, name='home'), path('users/<str:username>/', views.view_profile, name='profile'), ] Home page shows all posts, post includes avatar of post's author and avatars are visiable. When i change page to profile to see all posts of one author, django is looking for static files in weird way, by adding users/str:username/ at the beginning of path. e.g. '/users/TestUser/static/images/male.png', when correct path is 'static/images/male.png'. Why django looking for static files in that way and how to 'fix' it? Tree looks like this: project app app_stuff project project_stuff static images male.png Settings are like this: STATIC_URL = '/static/' MEDIA_URL = '/images/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, "static"), ] MEDIA_ROOT = os.path.join(BASE_DIR, 'static/images') -

Adding more than one model using Django ModelFormMixin in views.py
I have a Django related problem. I have two models; Model A & Model B. Model B is related to Model A trough a foreign key. In my views.py I have a CBV for a Single instance of Model A using generic.DetailView & generic.ModelFormMixin. I'm now wondering if there is a way to pass in more than one instance of a model in this view. At this point, I'm only able to pass in the Model A (which enables me to change values of the model in the DetailView). The idea would be something like this (this is ofc not working): #views.py class SingleModelA(generic.DetailView, ModelFormMixin): model = ModelA, ModelB I assume this would probably also require some changes in the post() method as well, which at the moment looks like this: def post(self, request, *args, **kwargs): self.object = self.get_object() form = self.get_form() if form.is_valid(): return self.form_valid(form) else: raise ValueError(f"INVALID FORM: {form}") I am able trough get_context_data() to present the ModelB instances belonging to this instance of ModelA, but I would like to access the ModelB instance's form in order to update ModelB straight from ModelA's DetailView. Any help is much appreciated! -
How to dynamically change a form in django based on user input (before submission)
I'm doing a web page that contains a form that must be changed dynamically based on the previous user inputs (before it's submitted). For example, if a name ends up with the string S.L, it needs to automatically span the rest of the fields to introduce the company data, if not it must submit the form with the default values or with any value at all. The form inherits from a model and everything is rendered as a crispy form. In the views.py I have: @login_required def form_home(request): if request.method == 'POST': Inputs = InputsForm(request.POST) if Inputs.is_valid(): inp = Inputs.save(commit=False) inp.author = request.user inp.email = request.user.email data = {'email': request.user.email, **Inputs.cleaned_data} obtain_calculate_create_send(data) inp.save() messages.success(request, f'Your form is valid!') return redirect('result/' + str(inp.pk) + '/') else: messages.warning(request, f'Please, check the inputs and enter valid ones') content = {'Inputs': Inputs, 'title': 'valuations'} else: Inputs = InputsForm(request.POST or None) content = {'Inputs': Inputs, 'title': 'valuations'} return render(request, 'valuations/form_home.html', content) In forms.py: class InputsForm(forms.ModelForm): # Basic Info country_choices = import_lists('Countries', equal=True) years = import_lists('years') name = forms.CharField(label='Company Name', initial='Example.
