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 add an editable field in the django admin that is not directly linked to a model field?
How to add a custom editable field in the django admin and then transform it before storing it in a field in the model? Given this Model: import json from django.db import models from django.core.serializers.json import DjangoJSONEncoder class Foo(models.Model): _encrypted_data = models.TextField(null=True, blank=True) @property def data(self): encrypted = self._encrypted_data if not encrypted: return {} return json.loads(decrypt(encrypted)) @data.setter def data(self, value): if not value: self._encrypted_data = {} return self._encrypted_data = encrypt( json.dumps(value, cls=DjangoJSONEncoder) ) The field Model._encrypted_data contains encrypted data. The property Model.data makes it easy to work with the decrypted data in the code: encrypt/decrypt automatically. I am looking for an editable admin field that represents the Model.data property. I started to explore a custom Admin Form but I am not sure how to pass the decrypted data to the field and then save it on the model. class FooAdminForm(forms.ModelForm): class Meta: model = Foo fields = '__all__' data = forms.JSONField(label='Data', required=False) class FooAdmin(admin.ModelAdmin): form = FooAdminForm -
FileField in Django does not send file to its form request
I have a Django form where I upload an image through an input type file. class Form(forms.Form): photo = forms.FileField( label="Photo", widget=forms.FileInput( attrs={ 'class': 'form-control', } ) ) I wrote the next view: def upload(request): context = {} if 'photo' in request.POST: form = Form(request.POST, request.FILES) if form.is_valid(): handle_uploaded_file(request.FILES["photo"]) else: print(form.errors) else: form = Form() context['form'] = form return render(request, 'app/upload.html', context) def handle_uploaded_file(file): with open('app/upload/'+file.name, 'wb+') as destination: for chunk in file.chunks(): destination.write(chunk) When I send the form the request does not recieve any file, even if I loaded a file before. I am able to show by javascript jpeg files loaded when the field has changed. So the field is loading files but is not sending theme in the request. Form does not check the validation form.is_valid(): it says it is required even when I have uploaded a file .jpeg Error shown in print(form.errors): <ul class="errorlist"><li>photo<ul class="errorlist"><li>This field is required.</li></ul></li></ul> I leave my template form here: <form action="" method="post" id="search_face_form" style="width: 100%;"> {% csrf_token %} <div class="row"> <div class="col-sm-4"> <div class="input-group-sm mb-4"> <label for="floatingInput">Archivo de búsqueda</label> {{ search_form.face }} {{ search_form.face.errors }} </div> </div> <div class="col-sm-6"> <img id="search_face_img" src="{% static 'cameras_admin/img/not_found.jpg' %}" style="display: none; max-height: 25vh;"> </div> <div … -

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.

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. -
Azure mobile app service keep getting it's pyodbc library version change without any actions
We have a Django/React mobile app that is hosted in Azure with the an app service plan (python 3.8.17) on Linux. 2-3 times a week, it stops working because the version of the pyodbc changes without any action on our side. We need to log into the SSH and switch the library libmsodbcsql-17-10.so.4.1 to libmsodbcsql-17-10.so.2.1 and then everything comes back to normal. What can cause this issue ? We checked if it was planned maintenance or any other Azure service that took action of some sort but couldn't find anything. -
Django unittest. Extract pk of a created object using .post method
Im studying some Python courses and i've got a project fully dedicated to unittest and pytest. The problem I have here is that i use the client.post method to create a note. My reviewer asked me get the note i just created using its pk. Have no idea how to do it. This is the code i currently have : def test_user_can_create_notes(self): response = self.auth_another_author.post(URL_NOTES_ADD, data=self.form_data) self.assertRedirects(response, URL_NOTES_SUCCESS) self.assertTrue(Note.objects.filter( title=self.form_data['title'], text=self.form_data['text'], slug=self.form_data['slug']).exists()) So i need to get the note object by pk and then check with assertEqual if its fields match the self.form_data fields I also tried getting the freshly created object using get and filter by the slug field. But that did not convince my reviewer -

Which Certificate Authorirties can issue an X.509 certificate for document signing in PEM format?
I am looking to build a custom document signing solution in my Django application using PyHanko. I want to use the certificates from a CA for this purposes. However majority of CAs that I reviewed either offer the complete document signing service or they provide certificate as tokens/Yubikey. Only Digicert is the provider that I could find which allows to download the certificate and then use it manually. Are there any other CAs that allow to download a dcoument signing cert in PEM etc format? -

DRF doesnt populate field label when using source
So, I have some model with few fields I want to expose over REST API: class MyModel(models.Model): field1 = models.TextField(verbose_name="Field 1") field2 = models.TextField(verbose_name="Field 2") and have corresponding serializer: class MySerializer(serializers.ModelSerializer): class Meta: model = MyModel fields = ('field1', 'field2') This way it works fine: using GET I retrieve fields values, and using OPTIONS I retrieve secondary fields information (e.g. if the field is required, help text, and label) The problem is that I don't want to expose real fields name, and I want to use some other name instead, for example: field1 and secondField. For that I modify my serializer: class MySerializer(serializers.ModelSerializer): secondField = serializers.CharField(source='field2') class Meta: model = MyModel fields = ('field1', 'secondField') Now I receive correct values on GET, but fields labels are wrong on OPTIONS: for second field I receive "Secondfield" instead of "Field 2" How do I get correct field label when using source? -

django-livereload-server installation
I am new to django and trying to install django-livereload-server In the installation guide, somewhere says: You need to inject the loading of the livereload javascript. You can do this in one of two ways: Through middleware by adding 'livereload.middleware.LiveReloadScript' to MIDDLEWARE_CLASSES (probably at the end): MIDDLEWARE_CLASSES = ( ... 'livereload.middleware.LiveReloadScript', ) Through a templatetag in your base.html (or similar) template: {% load livereload_tags %} ... {% livereload_script %} For the first solution, I've noticed there is no MIDDLEWARE_CLASSE = () in the settings.py file (django 4.2.4). Theres only a MIDDLEWARE_CLASSE = [] list, and putting 'livereload.middleware.LiveReloadScript' in it does not work. (Live reload runs, but can't refresh the page.) Where should I put 'livereload.middleware.LiveReloadScript' to get it to work? Whats the instruction for the second solution? I don't see the base.html in my project/ app. Should I create it myself?
