Passing a date to a queryset based on a button click in Django
I have Manifest View that querys date_scheduled and returns distinct values. I pass that queryset to a template and loop over the values and present them as buttons on the HTML file. I am able to click any button and pass the corresponding date into the URL,((localhost/schedule/2019-06-20) when I click on the June, 20 2019 button) thus redirecting me to my RoastManifestDetailView. Now I want to be able to filter my RoastManifestDetailView based only on the date passed to the URL (or which date button was clicked). I have tried RoastManifest.obejects.filter(date_scheduled__date=date.today())just to see if I could return anything schedule for today but I keep getting Fielderrors (Unsupported lookup 'date' for DateField or join on the field not permitted.). Please note I know that is not the exact queryset for me. I wish to pass in a variable into the queryset. This is the model: (NOTE: roast_order is in there only to allow for use of adminsortable2 library) def batch_number_incrementer(): current_max = RoastManifest.objects.order_by('-batch_number').first() if current_max: return current_max.batch_number + 1 else: return 8000000 batch_number = models.IntegerField(unique=True, default=batch_number_incrementer, ) product = models.ForeignKey(Product, related_name="products", on_delete=models.PROTECT) date_scheduled = models.DateField() roaster_profile = models.ForeignKey(RoasterProfile, on_delete=models.PROTECT) roast_order = models.PositiveSmallIntegerField(default=0, blank=False, null=False) class Meta: ordering = ('roast_order',) This is … -
SSL error in Django MySQL Connection (2026 SSL_CTX_set_tmp_dh failed)

django-filter filter on annotated field
class EventViewSet(viewsets.ModelViewSet): queryset = Event.objects.all() serializer_class = EventSerializer def get_queryset(self): return super().get_queryset().annotate( is_active=ExpressionWrapper( Q(start_date__lt=timezone.now()) & Q(end_date__gt=timezone.now()), output_field=BooleanField() ), ) search_fields = [ 'name', 'short_desc', 'desc', ] filterset_fields = [ 'is_active', ] I have this ViewSet that I want to filter on an annotated field, normally you can simply just filter on the annotation in django querysets, however the above combined with this serializer: class EventSerializer(serializers.ModelSerializer): is_active = serializers.SerializerMethodField() @staticmethod def get_is_active(obj): return obj.is_active class Meta: model = Event fields = [ 'timestamp', 'id', 'name', 'short_desc', 'desc', 'start_date', 'end_date', 'is_active', ] I haven't looked deep into the source code but I'd assume it would do a simple qs.filter for the fields in filterset_fields but I'm getting this beautiful error that fails to explain much(at least to me): 'Meta.fields' contains fields that are not defined on this FilterSet: is_active -
Django is not sending me an email when there is an error 500
After deploying my website, I would like to get an email with the errors when there is an error 500. I am able to send normal emails with send_mail. I alsp have DEBUG= False, ADMINS=[('name'),('email')] andSERVER_EMAIL = "domain email", however I and not getting any emails. I believe it is because I created a custom template for handler500 urls.py handler500 = myapp.error_500 views.py def error_500(request): data = {} return render(request,'.../error_500.html', data) How do I send the email with an error? -
Is it possible cache the whole page in Django?
I'm currently working this website. The problem is that the pages takes 3-4 seconds to get the first bye, and I think it's because query to load data in the pages is very slow. In the store page, it basically uses an object of a store to show the store's basic information and uses ForeignKey relation to access the store's images. In addition, it uses ManyToManyField to access the store's similar stores which are a store object as well. For this solved, I used prefetch_related and select_related so minimized many of duplicated queries. But still it shows a low performance. After that I thought, I could improve it with caching, so I did the below. To be honest, what I expected with caching was like super fast loading as it is supposed to store all the processed queries and just show the data from the requested cache. But, to be honest, it still shows 3-4 seconds loading performance. Am I using the cache in a wrong way? settings.py ... CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.db.DatabaseCache', 'LOCATION': 'django_cache', } } ... views.py class StoreDetailView(View): def get(self, request, *args, **kwargs): store_domainKey = self.kwargs['store_domainKey'] cache_store = 'store-{0}'.format(store_domainKey) store = cache.get(cache_store, None) if … -

Django ORM: filter for tuples of foreign key attributes
I'm writing a matching service that will match you with profiles based on overlapping expertise. E.g. if you are REQUESTING python expertise, it will match you with folks OFFERING python expertise. I'm having trouble determining how to structure that query with the Django ORM.

strange data display in select at Django

How does one save Django objects to models dynamically using functions?
I have several models that inherited an abstract model. With Django Rest Framework, I'm creating a custom action. I'm trying to save models based off an argument provided when utilizing the function: def mover_func(blobs, noteModel, commentModel): myself = blobs.get_object() U1(author=myself.author, title=myself.title, summary=myself.summary).save() class P1ViewSet(viewsets.ModelViewSet): queryset = PNote1.objects.all() serializer_class = PNote1Serializer @action(detail=True, methods=['get']) def pnote_move_to_unote(self, request, pk): mover_func(self, blah1, blah2) return Response({'status', 'Done'}) U1 is one of the models inheriting the abstract model. Later on, other viewsets such as P2ViewSets, P3, etc. are included, I need to save them to the models U2, U3, etc. There's more unrelated stuff than that, but I just wanted to minimize it for readability. I was thinking of adding an argument to mover_func like mover_func(self, blah1, blah2, U1) U1 being the model that should be creating and saving the object, but my recollection of previous experiences in Django 2.2 tells me that won't work... Again, something helpful is that the attributes author, title, and summary are the same across U1-->UInfinite (if you forgot that these models inherited from the same abstract model). -
Problem sending information between Django template and views using AJAX call
I used an ajax post request to send some variable from my javascript front end to my python back end. Once it was received by the back end, I want to modify these values and send them back to display on the front end. I need to do this all without refreshing the page. With my existing code, returning the values to the front end gives me a 'null' or '[object object]' response instead of the actual string/json. I believe the formatting of the variables I'm passing is incorrect, but it's too complicated for me to understand what exactly I'm doing wrong or need to fix. This is the javascript ajax POST request in my template. I would like the success fuction to display the new data using alert. $.post({ headers: { "X-CSRFToken": '{{csrf_token}}' }, url: `http://www.joedelistraty.com/user/applications/1/normalize`, data: {arr}, dataType: "json", contentType : "application/json", success: function(norm_data) { var norm_data = norm_data.toString(); alert( norm_data ); } }); This is my Django URLs code to receive the request: path('applications/1/normalize', views.normalize, name="normalize") This is the python view to retrieve the code and send it back to the javascript file: from django.http import JsonResponse def normalize(request,*argv,**kwargs): norm_data = request.POST.get(*argv, 'true') return JsonResponse(norm_data, safe = … -

No matching object on query during save() override on model - DoesNotExist error thrown
I'm overriding my Model save() to check and see if there is a Consumer (related object) that already exists with the email entered. When a Consumer does exist with a matching Email, the code executes as expected and associates the Case to the correct Consumer. However, if there is not an existing Consumer that exists with a matching Email, I'm receiving the error: "DoesNotExist: Consumer matching query does not exist." I've tried adjusting the save() method, however to me it looks correct (obviously, could be wrong here). Models.py class Case(models.Model): ... def save(self,*args,**kwargs): if Consumer.objects.get(email__iexact=self.email): self.consumer = Consumer.objects.get(email__iexact=self.email) else: consumer = Consumer(first_name=self.first_name,last_name=self.last_name,email=self.email) consumer.save() return super().save(*args,**kwargs) The expected results is to create a new Consumer object in the case that the Email entered on the Case does not match an already existing Consumer's email. Instead, it throws this error. -
How to highlight and get informations from elasticsearch-dsl search in django?

How to use purchased UI Theme with Django
I'm working with Django framework and I've recently purchased a dashboard Theme in order to give to my application a nice front end. My idea is to use styles, components, fonts and everything else provided in the Theme through in Django's templates. The product that I bought is called architectui-html-pro-theme. According to documentation provided the template is powered by jQuery, Bootstrap4 & Webpack The installation process of the Theme consist of: 1) Download files 2) Run npm install 3) and then start the application thought npm run start After all that, what i got is a nice Demo of the Theme running on http://localhost:8081 Great... But none further informations is provided regarding how to make the Theme works in My Django application. It's looks like the Theme installed a lot of dependencies (node_modules directory ) so I think to make it work in my Django project it is not just a matter of copy and paste the full directory in some "static" folder and just make reference some main.css style file in my "base.html" file. I have already asked the provider but no answer so far. This is the file structure of the Theme: .babelrc .gitignore architectui-html-pro <dir> node_modules <dir> … -

This entire communication process is done by rabbitmq. when an http request arrives at a certain endpoint the application django sends a message in a queue this process is working to consume the answer I thought about launching a theader that consumes the answer queue. I can launch theader but the client (django) closes the connection with rabbitmq my app ready from django.apps import AppConfig from rpc.rpc_queues import RcpOrder class SaleConfig(AppConfig): name = 'sale' def ready(self): r = RcpOrder() r.daemon = True r.start() my rpc interface class RpcInterface(Thread): host = None queue = None def __init__(self): #cria conexao TCP self.connection = pika.BlockingConnection( pika.URLParameters(self.host) ) #cria um canal virtual que server para o envio e consumo de mensagens self.channel = self.connection.channel() #declara a queue criando se for necessario result = self.channel.queue_declare(queue='', exclusive=True) self.callback_queue = result.method.queue super().__init__() def on_response(self, ch, method, props, body): #verifica se a mensagem foi para este consumer if self.corr_id == props.correlation_id: self.response = body def call(self, body): self.response = None #cria um id unico … -
returning related field in template
I have the following classes, I can get the related objects through this {{plantpart.fraction_id.fraction}} going up the models, but I want to go the other way. I know I need a related_name to avoid the _set ending and it needs to be in a nested for loop. So how do I correct the following: {% for f in fractions %} {% for pp in plantparts%} {{pp.plantparts.fraction}} {% endfor %} {% endfor %} class Fraction(models.Model): fraction_id = models.AutoField(primary_key=True) composition_id = models.ForeignKey(Composition, db_column='composition_id', on_delete = models.PROTECT) fraction = models.CharField(max_length=20, choices = FRACTIONS) class PlantPart(models.Model): plantpart_id = models.AutoField(primary_key=True) fraction_id = models.ForeignKey(Fraction, db_column='fraction_id', on_delete = models.PROTECT, related_name='plantparts') taxon_id = models.ForeignKey(Taxon, db_column='taxon_id', on_delete = models.PROTECT, related_name='plant_taxon', blank=True, null=True) part = models.CharField(max_length=100) weight = models.DecimalField(max_digits=10, decimal_places=3) quantity = models.DecimalField(max_digits=10, decimal_places=3) p.s. I know I don't need to use an id, but this connects to an existing database. -
Are Django models tightly coupled with databases?
Are Django Models tightly coupled with databases? I want to create a web application using Django framework, but I don't want to use any database. By this, I mean that my data is stored in the network file system and I have already written python functions to read/write data from/to the file system. How can I go about creating such an application using Django?
