Pdf format output is scattered in django
Hi I wanted to create invoice using WeasyPrint. I would like get a well formatted print as output for invoice. I'm using following function to create pdf: from weasyprint import CSS, HTML def render_to_pdf(context, file_name): file_data = render_to_string('order_detail.html', context) html = HTML(string=file_data).write_pdf( target='collections/%s' % (file_name), stylesheets = [CSS(string='body { font-size: 7px }')] ) fs = FileSystemStorage("") with fs.open("collections/" + file_name) as pdf: response = HttpResponse(pdf, content_type="application/pdf") response['Content-Disposition'] = '"attachment; filename="%s"'% (file_name) print("pdf working") return response In the latest version I used stringformat but earlier I tried with normal jinja templating and output was same. here is my html: {% load static %} <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Email</title> <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous"> <style> .container { border: 1px solid #585696; padding: 0; } .header { background-color: #585696; padding: 1.5rem; } h1.text-center { color: #fff; text-align: center; } .text-center { text-align: center; color: #585696; } .text-content { padding: 2rem; } .order-header{ color: #585696; margin-top: 1rem; } .table-stripped{ width: 100%; border: 1px solid #585696; } .title-bar { background-color: #585696; color: #fff; } th, td { text-align: center; border-bottom: 1px solid #585696; } tr { border-bottom: 1px solid #585696; } .address-time { margin-top: 0; … -

New Django project admin urls are somehow being overridden by prior project Django-Allauth settings
I have a new project, using DRF, and when trying to login to admin panel I get an error stating that the page not exist. The problem is that the url being generated when entering the current url is the same url that I used in my prior project using Django-Allauth. I have checked the current project for any traces of Django-Allauth and there are none. I checked the DB to make sure it was empty upon initiation of the project, and it was. What could be the problem here? current url.py urlpatterns = [ path('admin/', admin.site.urls), ..., ] prior urls.py path("accounts/", include('allauth.urls')), When I try to login to admin on localhost: http://127.0.0.1:8000/admin/ it redirects to old project's path of: http://127.0.0.1:8000/accounts/login/?next=/admin/login/%3Fnext%3D/admin/ resulting in an error stating page not found. I cleared cache by restarting project with Pycharm's Invalidate Cache/Restart but that did not resolve the issue. Any guidance is appreciated. -

How do i display multi images in two column grid in django
I Have tried using the forloop.counter but it makes the whole grid look messy and plus it only shows three pictures in the grid when you click a picture to have a detail view and sliding to see the other pictures it wont show other pictures as i have about eight pictures posted in the same grid. if the pictures are few i have to go back into the forloop.counter and change the divisible number which is not a good practice how best do i go about it. <div uk-lightbox> <div class="grid grid-cols-2 gap-2 p-2"> {% for p in photos %} {% if forloop.counter|divisibleby:3 %} # The First image goes here <a href="{{ p.pic.url }}" class="col-span-2"> <img src="{{ p.pic.url }}" alt="" class="rounded-md w-full lg:h-76 object-cover"> </a> The second goes here <a href="{{ p.pic.url }}"> <img src="{{ p.pic.url }}" alt="" class="rounded-md w-full h-full"> </a> # the rest of the pictures goes <a href="{{ p.pic.url }}" class="relative"> <img src="{{ p.pic.url }}" alt="" class="rounded-md w-full h-full"> <div class="absolute bg-gray-900 bg-opacity-30 flex justify-center items-center text-white rounded-md inset-0 text-2xl"> + {{ forloop.counter }} more </div> </a> {% endif %} {% endfor %} </div> </div> After i tried the above this what i did again but … -
Unauthorized response using Firebase auth with DRF
I have created a drf API which I have connected to a react-admin frontend in order to have a ready-to-go dashboard interface and it works. But I want to implement firebase authentication into the frontend, and when I try to do that I get errors, and seems that my backend is reading my auth header because it is giving me the bearer token into the console but still gives me an unauthorized response. The backend I am using for the moment is sqlite and I have not created any custom user models, for the moment I am trying to log in from the front-end with an account from firebase. Here are my code samples: class FirebaseAuthentication(authentication.BaseAuthentication): def authenticate(self, request): token = request.headers.get('authorization') print(token) if not token: raise NoAuthToken("No auth token provided") try: decoded_token = auth.verify_id_token(token) uid = decoded_token['uid'] except Exception: raise InvalidAuthToken("Invalid auth token") if not token or not decoded_token: return None try: user = User.objects.get(username=uid) return user except Exception: raise FirebaseError("User does not exist") and here is the react configuration for the firebase auth provider const authProvider = FirebaseAuthProvider(firebaseConfig, firebaseOptions) const dataProvider = drfProvider('http://127.0.0.1:8000/api') export { authProvider, dataProvider } -
Stop a C /C++ extension in Django
Summary of the problem I am implementing a long-running C/C++ extension within a Django framework (called via a request POST). In some cases, the user may want to interrupt the calculation by just leaving/unloading the specific web page that calls the C extension. Is it possible to kill the extension from Python? Minimal Reproducible Example In order to reproduce the problem, we can make our own Fibonacci C extension. The call in Django is as follows: import fibonacci from django.views.generic.base import TemplateView # Computation class ComputationView(TemplateView): template_name = 'Generic/computation_page.html' @staticmethod def get_results(request): N=1000 if request.method == "POST": # When button is pressed # Long computations cs_min = fibonacci.fib(N) else: cs_min = None return render(request, ComputationView.template_name, {'cs_min': cs_min}) While the code in C is: #include <Python.h> // Compute the Minimal cutsets int Cfib(int n) { int fib1; int fib2; if (n < 2) return n; else{ Py_BEGIN_ALLOW_THREADS // Release GIL // Some stric operations in C Py_END_ALLOW_THREADS // Reacquire GIL return Cfib(n-1)+Cfib(n-2); } } // Our Python binding to our C function // This will take one and only one non-keyword argument static PyObject* fib(PyObject* self, PyObject* args) { // instantiate our 'n' value int n; // Order of cutset // … -

Problem with serializers creating an API with Django
I am writing an API with django and I am having this problem: When I create a serializer object, if I do it like this: document_serializer = DocumentSalesforceSerializer(data={ "AccountId": patient_id, "ContactId": patient_id, "Proveedor__c": "docline", "Servicio_asociado__c": "report", "Mapfre_Id__c": patient_id, "Status": "In Progress", "StartDate": document["createdAt"], "EndDate": "hoy", "Subject": document["category"], "Description": description, "SAV_fld_source__c": "docline", "SAV_fld_doclineExtId__c": id, "SAV_fld_doctor__c": "", }) document_serializer.is_valid(raise_exception=True) I get the following error: The translation infrastructure cannot be initialized before the apps registry is ready. Check that you don't make non-lazy gettext calls at import time. Reading on the internet some people said that I whould delete the data= part, so I left it like this: document_serializer = DocumentSalesforceSerializer({ "AccountId": patient_id, "ContactId": patient_id, "Proveedor__c": "docline", "Servicio_asociado__c": "report", "Mapfre_Id__c": patient_id, "Status": "In Progress", "StartDate": document["createdAt"], "EndDate": "hoy", "Subject": document["category"], "Description": description, "SAV_fld_source__c": "docline", "SAV_fld_doclineExtId__c": id, "SAV_fld_doctor__c": "", }) document_serializer.is_valid(raise_exception=True) But then I am getting this error: Cannot call `.is_valid()` as no `data=` keyword argument was passed when instantiating the serializer instance. Does anyone have and idea of what is causing the error? Thanks in advance for reading this question. -

I discovered that I could use a function to achieve my goal, but when I went to the admin page, in place of the data I wanted it to display, it would display <django.db.models.query_utils.DeferredAttribute object at 0x00000208375C9280> Here is my admin.py file: from django.contrib import admin from .models import RiskRegister, Category, Severity, RSev from account.models import Account class RiskRegisterAdmin(admin.ModelAdmin): list_display = ['id', 'user', 'user_dept', 'date', 'category', 'roles', 'responderID', 'severity', 'action_taken_explanation', 'created_at'] list_filter = ['id', 'user', 'date', 'category', 'roles', 'responderID', 'severity', 'action_taken_explanation'] search_fields = ['id', 'user', 'user_dept', 'date', 'category', 'roles', 'responderID', 'severity', 'created_at'] def user_dept(self, obj): return Account.department And my models.py file containing the Account model: class Account(AbstractBaseUser, PermissionsMixin): username = models.CharField(max_length=150, unique=True) email = models.EmailField(verbose_name='email', max_length=254, unique=True) department = models.CharField(verbose_name='department', max_length=100, editable=True) first_name = models.CharField(verbose_name='first name', max_length=254, blank=True) last_name = models.CharField(verbose_name='last name', max_length=254, blank=True) date_joined = models.DateTimeField(verbose_name='date joined', auto_now_add=True) last_login = models.DateTimeField(verbose_name='last login', auto_now=True) is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) How can I make it display what is in the department? -

Django + NGINX 404 Not Found
Whenever I run server using gunicorn --bind command, all static files load without any error. but when I try to access my domain It gives 404 error.

Key 'fieldname' not found in 'ModelForm'. Django 3.2
I am trying to override the get_form function in admin class in Django 3.2. I defined a custom permission for a specific user that can only view some defined fields of a model. It worked fine but when I tried to navigate to the change form of an object with the non-permitted users, I cannot be able to view the change form as superuser until other user closes the change form. So basically, override get_form method is not working at the same time for different kind of users. By the way I did not have any defined view because I am only using admin template as view, I am just only overriding admin template. I am new in django so I don't know that I am doing this correctly... Here is the admin class that I created and override get_form method(for instance I do not want to display surname if the user does not have the custom permission): class HumanAdmin(admin.ModelAdmin): fieldsets = ( ('Fields 1', {'fields': ('id','name', 'surname'),}), ) def get_form(self, request, obj=None, **kwargs): if request.user.has_perm('app_name.custom_permission'): self.fieldsets[0][1]["fields"] = ('id','name', 'surname') form = super(InventoryAdmin,self).get_form(request, obj, **kwargs) else: self.fieldsets[0][1]["fields"] = ('id','name') #I do not want to see if user does not have … -
DRF Pagination custom response without model APIView
Hello I have a project in Django, which performs several queries to different databases returning them in several endpoints, for this I use Pandas and DRF (APIViews). The problem arises when the response is very long and logically the server runs out of memory, I understand that I need to paginate the result but I have not found the way to do it because I do not use models or serializers, I do raw queries with pandas to make the queries. Is there any way to paginate the results the way I'm doing it? I leave some snippets of my code. class AffiliateAPIView(APIView): permission_classes = (IsAuthenticated,) def get(self, request): insurance = self.request.query_params.get('insurance', None) emergensys_df = pd.read_sql_query(general_attention(insurance), engine()) return Response(emergensys_df.to_dict(orient='records'))
