How to return an html file as a response python django
This is my views file: from django.shortcuts import render from django.http import HttpResponse def hellothere(request): return render(request, "hello.html") # use forward slashes Everything is right, the name of the file is right, but for some reason django keeps saying that "the template could not be found". What reasons could there be that django couldn't find the template? This views.py file is in an app called "playground" and the hello.html file is in a folder in playground called "templates". Also, I've already tried adding the filepath to the DIRS attribute in the TEMPLATES array and I've tried using the exact and relative path of hello.html instead of just "hello.html", yet the problem still persists. -
Generate PDF's Pages with a background image
I'm generating a pdf with Django. This is the code def generar_pdf(request): response = HttpResponse(content_type='application/pdf') response['Content-Disposition'] = 'attachment; filename="mi_archivo.pdf"' buffer = BytesIO() doc = SimpleDocTemplate(buffer, pagesize=letter) contenido = [ {"spaceBefore": 0, "spaceAfter": 15, "texto": "text 1", "tipo": 1, "negrita": False}, {"spaceBefore": 0, "spaceAfter": 0, "texto": "text 2", "tipo": 2, "negrita": False}, {"spaceBefore": 15, "spaceAfter": 15, "texto": "text 3", "tipo": 3, "negrita": False}, {"spaceBefore": 0, "spaceAfter": 0, "texto": "text 4", "tipo": 2, "negrita": False}, {"spaceBefore": 15, "spaceAfter": 0, "texto": "text 5", "tipo": 3, "negrita": False}, ... ] flowables = [] for item in contenido: parrafo = Paragraph(item['texto'], ParagraphStyle( name=name, fontName='Helvetica', fontSize=18, alignment=TA_LEFT, spaceBefore=item['spaceBefore'], spaceAfter=item['spaceAfter'] )) flowables.append(parrafo) doc.build(flowables) pdf = buffer.getvalue() buffer.close() response.write(pdf) return response In this pdf, I need each page to have a background image. I tried using PageTemplate this way: frame = Frame(inch, inch, doc.width - 2 * inch, doc.height - 2 * inch) template = PageTemplate(id='background', frames=[frame], onPage=add_background) doc.addPageTemplates([template]) But it only apply in the first page, and no to the others.In addition, it reduces the size where the information is displayed but i don't know why. -

Looking for a monorepo system to handle it all
I am currently working on X repositories. We would like to refine everything at work to use them within a monorepo. But here comes the point. The repositories include JavaScript (NodeJS, NextJs, ReactJs) [including TypeScript], a Django backend written in Python, and serverless functions. The JS parts are not the big problem. Here I use npm (we would change to pnpm) as package manager and VITE as bundler. My biggest problem is the Python part. We use pip currently and use a "requirement.txt" for the dependencies. I have already seen Nx and tried it. But the python plugin uses poetry . I can get it to work. But my boss doesn't want to switch to poetry unless it's absolutely necessary. Is there a monorepo that I can use without switching to poetry? Additionally, we want to upgrade to python 3.11. Otherwise there is a monorepo system which meets the requirements? Hours and hours of research -

How to insert placeholder in Django Admin text input
I've tried three methods, first as described in how-to-add-placeholder-text-to-a-django-admin-field and in the docs from django import forms class AppointmentAdmin(admin.ModelAdmin): def get_form(self, request, obj=None, **kwargs): kwargs['widgets'] = { 'name': forms.TextInput(attrs={'placeholder': 'Type here'}) } return super().get_form(request, obj, **kwargs) Then the method described in django-add-placeholder-text-to-form-field, slightly altered to get around Python errors. class AppointmentAdmin(admin.ModelAdmin): def get_form(self, request, obj=None, **kwargs): form = super().get_form(request, obj, **kwargs) form.base_fields['customer'].widget.attrs["placeholder"] = "Type here" return form Finally, using formfield_overrides: class AppointmentAdmin(admin.ModelAdmin): formfield_overrides = { models.TextField: { "widget":forms.TextInput(attrs={'placeholder':'Type here'})}, } None of these are working. I must be overlooking something simple? The relevant portion of models.py: class Appointment(models.Model): customer = models.ForeignKey(Customer, blank=False, null=True, default=None, on_delete=models.CASCADE, related_name='appointments') -

SSO authentication not working on cross-domain requests
I am trying to enable SSO on my website. The backend is on Django hosted on a different domain and frontend is on React on a different domain. The backend is making Djoser package to handle social authentication. The sessionId which I receive in the form set-cookie header is not getting saved in browser cookies even though Access-Control-Allow-Credentials is true due to which SSO is failing. The same is working if my backend and frontend are on the same domain. Is there any solution to this? I am expecting SSO authentication on cross domain architecture but it is failing because session Id is not getting saved in browser cookies even though Access-Control-Allow-Credentials were enabled.
