DRF - How to change serializer.PrimaryKeyRelatedField's filter lookup key with condition?
I am trying to change serializers.PrimaryKeyRelatedField's filter lookup key based on other boolean field on serializer but I could not be successful. PrimaryKeyRelatedField filtering by pk key by default. In some condition (if condition field on serializer sent as True), I just want to change that filtering key with another field on related model's field like remote_id. class SomeSerializer(serializers.Serializer): condition = serializers.BooleanField(default=False) model_pks = serializer.PrimaryKeyRelatedField(queryset=Model.objects.all(), many=True) I tried to create new field which is inherited from PrimaryKeyRelatedField and override get_queryset method (not sure to override correct method) so far but I could not access condition and model_pks fields values. class CustomPrimaryKeyRelatedField(PrimaryKeyRelatedField): def get_queryset(self): queryset = self.queryset # model_pks = sent model_pks if condition: return queryset.filter(remote_id__in=model_pks) return queryset.filter(id__in=model_pks) Also, I tried to use SerializerMethodField instead of PrimaryKeyRelatedField like; class SomeSerializer(serializers.Serializer): condition = serializers.BooleanField(default=False) model_pks = serializer.SerializerMethodField() def get_model_pks(self, value): pks = self.initial_data.get('model_pks', []) if value.get('condition', False): return Model.objects.filter(remote_id__in=pks) return Model.objects.filter(pk__in=pks) It's provide changing lookup key based on condition but this time I could not access model_pks values with serializer.validated_data. Is there any way to make conditional lookup key filtering using PrimaryKeyRelatedField? -
Frontend editing stopped working in Django CMS after installing application

How to correctly write custom Renderer to download file with django REST API
I am running a Django app where I can upload files. Now I want to download the files using django REST framework. I am trying to overwrite the custom renderer following the spare documentation on Renderers and on FileResponses as well as this question: How to return generated file download with Django REST Framework? My model: class FileCollection(models.Model): name = models.CharField(max_length=120, null=True, blank=True) store_file = models.FileField(storage=PrivateMediaStorage(), null=True, blank=True) creation_date = models.DateTimeField(null=True, blank=True) My views class PassthroughRenderer(renderers.BaseRenderer): media_type = 'application/pptx' format = 'pptx' def render(self, data, accepted_media_type=None, renderer_context=None): return data class FileView(viewsets.ReadOnlyModelViewSet): queryset = FileCollection.objects.first() Now I am lost.... It's not clear to me how I can use this renderer to create a download for my file. I'm very grateful for help or hints. Thanks so much -
Key error - "type" in django while migrating from existing mysql to mongodb through djongo
while migrating my existing database engine from SlqlLite to MongoDB through djongo ( a django ODM), I am facing this issue of key error, which simply means when a key and its associated value is not present in the dictionary of constraints, I am suspecting its because I am already having existing data model classes. The tutorials I followed were only about starting a fresh project through mongoDB. The key 'type' is not present in the dictionary within file scripts.py (library file). I got to know that through a simple modification of printing the dictionary, plz help me guys as I am a Django newbie! major suspect is identification_identification_slug_27be3d04': {'columns': ['slug'] in dictionary i dont even know type the type field stands for ? its not ven any constraints powershell screenshot settings.py affecting lines in schema.py -
Handle error of a specific time raised at any point
Occasionally we are getting OperationalError: FATAL and we have no idea why. I want to handle this error wherever it happens in the application and send me a personal email. I would also like to set up a system command call to inspect the database activity (I know this is a bad idea but it's the only thing I can think of to try to figure out why this is happening). How can I do this? Summarized: catch an error of a specific type raised at any point and handle it in a custom and granular way. -

Django ListView with post method, get_queryset does not come filtered
In my application i made a ListView, in this ListView i have to make a post so i'm defining the post method, in this post method i need the filtered get_queryset method, but it comes unfiltered as if it is default. I made some research and i've noticed method post() is ran before get_queryset(), my question is: Is there any way i can get the filtered get_queryset() in the post() method? Ex: def get_queryset(self): qs = super(FilteredListView, self).get_queryset() q = Q() if self.request.session.get('make_id'): q.add(Q(owner__make=self.request.session['auto_id']), Q.AND) if self.request.user.is_superuser: return qs.filter(q).distinct('id').order_by('-id') return qs.filter(q, owner=self.request.user.company).distinct('id').order_by('-id') def post(self, request, *args, **kwargs): if 'action' in self.request.POST: action = self.request.POST.get('action') if action == 'batch_approve': queryset = self.get_queryset() # i need the filtered queryset here, but it comes unfiltered return redirect('{}?{}'.format(reverse('flow:filtered_list'), request.GET.urlencode())) return redirect('flow:filtered_list') -

Is it possible to forward processed (in views.py) form data for further use?
I am new to django so sorry if I will not succeed to express myself clear enough. To begin with: I have build simple form to perform simple calculations and return result based on user input. Now I would like to add an option for user to generate PDF from these results, but I am not sure what kind of approach should I use. My first idea was to store calculation data in some sort of global variable and pass it to the view responsible for generating PDF. According to answer to this question there should be few ways to do that (but I am not sure if they fit because for example my url never changes). My second idea that since url never changes maybe data is still somewhere and can be accessed somehow? What I am trying to say, that I have calculation results passed in dictionary form (named context in my code) to results html template. Can I still access this dictionary and use it in another views.py function? Can somebody provide some insights or direct me to what kind of literature I should search (since I do not exactly know what approach I should take and … -

Issue with django POST requests and nginx
I have an nginx in front of my Django application, and I have a frustrating issue with POST requests. It seems that sometimes, the response of a POST request gets "lost" and is not returned to the browser. However, no error is generated. I have tested this with both uwsgi and gunicorn, and I can reproduce the same error under both application servers. My nginx config is quite simple: upstream django { server myapp:8000; # } server { listen 8000 default_server; location / { charset utf-8; #include uwsgi_params; #uwsgi_pass django; proxy_pass http://django; client_max_body_size 512M; # add_header X-XSS-Protection "1; mode=block" always; # add_header X-Content-Type-Options "nosniff" always; } location /media/ { alias /uploads/; add_header X-XSS-Protection "1; mode=block" always; add_header X-Frame-Options "SAMEORIGIN" always; add_header X-Content-Type-Options "nosniff" always; add_header Cache-Control "no-store" always; } location /static/ { alias /static/; add_header X-XSS-Protection "1; mode=block" always; add_header X-Frame-Options "SAMEORIGIN" always; add_header X-Content-Type-Options "nosniff" always; expires 1y; add_header Cache-Control "max-age=31536000"; } } The problem is, there is no consistent way to reproduce it.

Conditionally nest Django serializers
So, I have a foreign key to my User model in many of my models. Now, the serializers for these models are nested, in that they include the entire user object rather than just the id. I have done so as shown bellow: class BadgeSerializer(serializers.ModelSerializer): user = UserSerializer(read_only=True) class Meta: model = Badge fields = '__all__' It works as expected. However, I seldom find myself in a situation where I want just the id. I was wondering if there is a way to conditionally nest my BadgeSerializer... -

Django form save related object only if form is valid
I think I have a rather uncommon feature here, at least I couldn't find a answer. What I'd like to achieve is a text input with autocomplete on a related model with its label field. the given text should then get_or_create the related model. this already works but the problem is, that the new related model instance is saved on form submit no matter if the form is_valid or not. given the following situation and implementation (shortened for better overview) class Correspondent(models.Model): label = models.CharField(_("label"), max_length=100, unique=True) class Document(BaseModel): correspondent = models.ForeignKey( Correspondent, verbose_name=_("correspondent"), on_delete=models.PROTECT, related_name="documents", ) with the following form: class DocumentForm(forms.ModelForm): correspondent = forms.CharField( label=_("correspondent"), widget=forms.TextInput(attrs={"class": "awesomplete"}) ) class Meta: model = Document exclude = ["created_by", "modified_by"] def clean_correspondent(self, *args, **kwargs): # ToDo: don't save the FKed instance if complete form isn't valid user = self.initial["user"] data = self.cleaned_data["correspondent"] errors = {} try: obj = Correspondent.objects.get(label=data) except: obj = Correspondent(label=data, created_by=user, modified_by=user) obj.save() return obj so the problem here is obj.save() which is called before form.is_valid() and I couldn't figure a way yet how to solve this.

EMAIL_BACKEND = "sendgrid_backend.SendgridBackend" SENDGRID_API_KEY = os.environ.get("SENDGRID_API_KEY") views.py def index(request): if request.method == "POST": ContactUsForm = ContactUs(request.POST) if ContactUsForm.is_valid(): firstName = ContactUsForm['firstName'] fromEmail = ContactUsForm['email'] message = ContactUsForm['message'] send_mail(subject=f"{firstName} sent you a message", message=message, from_email=fromEmail, recipient_list=['toaddress@email.com']) return redirect('home') else: ContactUsForm = ContactUs() context = {'contactUs': ContactUsForm} return render(request, 'index.html', context) But when I submit the form, I get this error message TypeError: 'in <string>' requires string as left operand, not BoundWidget I dont know where I went wrong. This is the link I followed to send emails with sendgrid -
Why am i getting importerror: module not found when i have it installed already?
I am migrating from django-sqlite3 to postgresql and so I have installled postgresql and required modules(psycopg2) in my apache2 server. I have installed psycopg2 correctly- >>> import psycopg2 >>> psycopg2.__version__ '2.8.4 (dt dec pq3 ext lo64)' >>> psycopg2._psycopg.__version__ '2.8.4 (dt dec pq3 ext lo64)' Yet, it throws an error as follows-ImportError: No module named psycopg2._psycopg(as shown in my error.log file) I have searched all threads on stackoverflow and github but couldnt find any solution.
