Any documentation for Django firebase email verification web backend [closed]
Firebase has some features like email verification and password recovery link. So I'm new to this, so I was wondering whether these features should be handled in frontend or backend. Plus if it needs to be handled in backend,is there any documentation which shows how to use the firebase email verification codes in Django Thanks! -
How to handle a token key in a website made with django, django-rest-auth, and react?
First of all, I am pretty new to working with Rest APIs and tokens, I have learned the basics of Django and React and I've kinda made some projects using those, so I'm giving a shot at making a website with both of them. Since, registering is simple with django-rest-auth, it's been handled with just POSTING the user data. However, when making a login, the token was returned and I simply do not know how to handle it. I have searched many articles about tokens, but they were all about JWT which returns an access token and a refresh token. However, django-rest-auth returns a single token and I saved it inside a cookie using a 'universal-cookie' in React. Since I'm making an e-commerce website, and I do want to add some functionality to the website by enabling the users to change their email, last name, first name and username, I do need to know the username of the account as it is unique. So, I am wondering if it would be alright and a good practice to save the username inside a cookie, again using a universal-cookie. It'd also be appreciated if someone shows me a good article about "what … -
Dynamically delete and add forms to inline formset (single printed fields) in django
I wanna have a button to add a new form, as well as I wish a delete button, that deletes a selected form. I can add forms by now, but the added ones don't become submitted. I wanna be able to delete them with ajax, so they do not refresh the whole page too. How can I do this? I got the following code currently: template <tr class="item"> <td> {% render_field forms.service name="service" class="" required="" %} </td> <td> {% render_field forms.unit name="unit" class="" required="" %} </td> <td> <a href="javascript:void(0)" id="inline-sex" data-type="select" data-pk="1" data-value="" data-title="Select sex" class="editable editable-click editable-open" style="color: rgb(152, 166, 173); display: none;">not selected</a> {% render_field forms.quantity name="quantity" class="" required="" %} </td> <td> {% render_field forms.unit_price name="unit_price" class="" required="" %} </td> <td> {% render_field forms.vat_rule name="vat_rule" class="" required="" %} </td> <td></td> {% if formset.can_delete %} <td>{{forms.DELETE}}</td> {% endif %} </tr> {% endfor %} <tr> <td colspan="4"> <input type="button" value="Add More" id="add_more" /> </td> </tr> <tr class="total"> <td colspan="3"></td> <td>Total: $385.00</td> </tr> <script> $("#add_more").click(function () { cloneMore("tr.item:last", "service"); }); function cloneMore(selector, type) { let newElement = $(selector).clone(true); let total = $("#id_" + type + "-TOTAL_FORMS").val(); newElement.find(":input").each(function () { let name = $(this) .attr("name") .replace("-" + (total - 1) + "-", … -
Django AsyncWebsocketConsumer with ws: and wss: protocol
I'm working on an application that requires me to send data packets to and from server. I'm using AsyncWebsocketConsumer in Django and WebSocket in JavaScript to create a socket connection. The problem I'm facing is that my application works with ws: protocol but when I switch to wss:, the requests don't appear on the server at all. Here are more relevant details about my project: myproject/settings.py ASGI_APPLICATION = 'myproject.routing.application' CHANNEL_LAYERS = { 'default': { 'BACKEND': 'channels_redis.core.RedisChannelLayer', 'CONFIG': { "hosts": [('127.0.0.1', 6379)], }, }, } myproject/routing.py application = ProtocolTypeRouter({ 'websocket': AuthMiddlewareStack( URLRouter( chat.routing.websocket_urlpatterns ) ), }) chat/routing.py websocket_urlpatterns = [ re_path(r'ws/(?P<room_name>\S+)/$', consumers.ChatConsumer), ] chat/consumers.py from channels.generic.websocket import AsyncWebsocketConsumer class ChatConsumer(AsyncWebsocketConsumer): async def connect(self): await self.accept() # ... more code ... # some self.send() statements to send data over Socket JavaScript ... wsPath = "wss://" + window.location.hostname + ":8000/ws/" + roomName + "/"; webSocket = new WebSocket(wsPath); webSocket.onopen = ... When I use ws: instead of wss: in above JavaScript code, I see following in my server: WebSocket HANDSHAKING /ws/<room-name>/ [127.0.0.1:44450] WebSocket CONNECT /ws/<room-name>/ [127.0.0.1:44450] but I see no WebSocket requests when I use wss: I'm running python manage.py runserver.

Writing custom middleware in Django 2.2, control not coming to __call__() method at all
I'm trying to create custom middleware within Django 2.2 application Below is my settings file : MIDDLEWARE = [ 'html_template.middleware.CorsMiddleware' ] and my middleware code is: class CorsMiddleware: def __init__(self, get_response): import ipdb; ipdb.set_trace() self.get_response = get_response # One-time configuration and initialization. def __call__(self, request): import ipdb; ipdb.set_trace() # Code to be executed for each request before # the view (and later middleware) are called. response = self.get_response(request) # Code to be executed for each request/response after # the view is called. return response Now according to Django 2.2 documentation https://docs.djangoproject.com/en/2.2/topics/http/middleware/ __call__() method should be executed every time a request hits the server, but the weird part is even though the __init__() method is executed but the control never reaches the __call__() method. Any thoughts? -
Accessing a database table using docx in python
Ihave a django db table called my_defect_table in database table i have an item which is a float, it is called number_in_table. I am trying to use docx module in order to access this table and generate a word document with this number. Main.py import docx import docx2pdf from docx2pdf import convert from django.http import FileResponse from django.shortcuts import render from site1app.models import my_defect_table def making_a_doc_function(request): doc = docx.Document() doc.add_heading(my_defect_table.number_in_table) doc.save('thisisdoc.docx') #converting the generated docx into a pdf file convert("thisisdoc.docx", "output.pdf") generated_doc = open('output.pdf', 'rb') response = {"generated_doc": FileResponse(generated_doc)} return render(request, 'doc.html', response) the problem is that when i am trying to access my_defect_table.number_in_table it is not reading the values. i just get an error that says 'DeferredAttribute' object is not iterable. I know that my document generation works because when i swap my_defect_table.number_in_table for just text "hello", a document is generated with "hello" as the heading. Any ideas where im going wrong? -

Django different models versions on the same data
Currently I'm working on some Django + Postgres project. There I currently have 2 branches: dev and master. Usually as soon as I finish developing and testing a new feature (I develop this part of the project on my own, no other developers involved) I merge dev into master and then upload it onto the production server (dev was uploaded and tested on the test server before, of course). And that's it. That WAS it. Now my boss wants me to use beta versions, like an extra layer between master and dev. So, now when I want to merge dev into master first I should merge it into new beta branch. Then beta is uploaded onto the master server but under its own sub-domain, like beta.some.site.com. Some trusted users will have access to this subdomain and will be able to use the new unstable features. However, if they discover some blocking bug they can switch back to the stable version (some.site.com, without beta prefix). Then, after some significant time and trusted user reviews beta gets merged into master. Our main goal with such move is to decrease the amount of hotfixes we usually do after introducing another version to the … -

django-storages aws s3 costs reduction and calculation
i would like to calculate and reduce my costs for my file storage on s3. I have deploy my django app to elastic beanstalk in Europa (Frankfurt) eu-central-1. At the moment i use a t2.micro ec2 instance, a db.t2.micro PostgreSQL database and a additional standard s3 bucket beside the standard bucket from elastic beanstalk. I think the cost for the ec2 and the database are easy manageable because after the free tier i would like to use reserved instances. But the s3 costs make me worry. Users can upload and download files to my application. My django application use django-storages to manage the files but i don't know what happened in the background and for what i must pay. For example i have a storage class and a model with a file field named export: class PrivateMediaStorage(S3Boto3Storage): location = 'private' default_acl = 'private' custom_domain = False class Document(models.Model): name = models.CharField(max_length=255) ... class FileDocument(models.Model): document = models.ForeignKey('documents.Document', on_delete=models.CASCADE, related_name="files") file = models.FileField(storage=PrivateMediaStorage()) ... - - Upload I store files thats a user upload like this: document = Document.objects.get(...) files = request.FILES.getlist('files[]') if files: for file in files: try: file_obj = FileDocument.objects.get(name=file.name, document=document) file_obj.file.save(file.name, file) file_obj.save() except FileDocument.DoesNotExist: file_obj = FileDocument() … -

Pipfile not showing all installed packages
I am using pipenv as the virtual environment in a Django project. I installed the Django third-party package django-allauth-2fa via pipenv install django-allauth-2fa==0.8. In the package's docs regarding its installation it says: note that this will install Django, django-allauth, django-otp, qrcode and all of their requirements. After successfull installation I wanted to check if this is in fact the case, however my Pipfile did not show any new installation besides django-allauth-2fa. I double checked with pip freeze from within the virtual environment shell and got a list back, in which all the package's dependencies were indeed listed (qrcode, django-otp, etc.) My question is hence: Do I have a misunderstanding about how the Pipfile works? I assumed that the file shows all the packages that are installed in my virtual environment. Or are only those shown that were installed via the pipenv install <package> command but not those that were installed alongside packages installed via pipenv install <package>? -

How would I achieve to get the correct pks for contact_person into contacts? I thought about generating a dict in the models method like [{"name": "bart", "id": 1}, {"name": "Rita", "id": 2},]. But sure there is a smoother way? views.py: class CustomerListView(SingleTableView): model = Customer context_object_name = 'customer' table_class = CustomerTable template_name = "customerlist.html" def get_queryset(self): qs = super(CustomerListView, self).get_queryset() return list(qs) -

Is there any way to add CSS/JS files dynamically in Django templates?
Actually I am trying to implement a content delivery application in Django to support my SASS based application with dynamic style sheets and Javascript files. I searched a lot but wasn't able to find a single solution for this. In a nutshell, I simply want to implement an application in which views fetch the CSS/JS files and then use the URLs of these views in a Django template (HTML) so that the response of those views as the content of a CSS/js file could include in the Django template. I would be very grateful if someone helps me with this problem. I am stuck on this and not able to proceed further with my project. It sucks a lot. Thanks a lot in advance. -
Why is my login route not working in django 3?

How to save initial object to database that has a self reference in Django
Let's say I have a custom Django model User with a self-reference: Class User(models.Model) name=models.CharField(max_length=80) . . . user_created = models.ForeignKey( 'self', on_delete=models.PROTECT, ) As you can see, I want the user_created field to have a NOT NULL constraint. Not surprisingly, if I try to create the first ever user without a user_created reference like so... User.create(name='Bob') <-- Remember I'm the first ever user in the DB I get: django.db.utils.IntegrityError: null value in column "user_created" violates not-null constraint I get why Django throws this error. I have declared a NOT NULL CONSTRAINT for the user_created field, but I can't provide anything because no other user currently exists in the database. I have previously dealt with this by first creating a User object, and then applying the Not Null constraint, which works fine except when I run tests. When I run tests Django creates a new database and there is no way for me to supply the first user to that test database. I worked around this by creating a CustomTestRunner(DiscoverRunner) that drops the constraint before the test database is created, which also works fine. However, I was wondering if anyone else out there ran into this problem and found a … -

Is it possible to generate PDF with StreamingHttpResponse as it's possible to do so with CSV for large dataset?
I have a large dataset that I have to generate CSV and PDF for. With CSV, I use this guide: https://docs.djangoproject.com/en/3.1/howto/outputting-csv/ import csv from django.http import StreamingHttpResponse class Echo: """An object that implements just the write method of the file-like interface. """ def write(self, value): """Write the value by returning it, instead of storing in a buffer.""" return value def some_streaming_csv_view(request): """A view that streams a large CSV file.""" # Generate a sequence of rows. The range is based on the maximum number of # rows that can be handled by a single sheet in most spreadsheet # applications. rows = (["Row {}".format(idx), str(idx)] for idx in range(65536)) pseudo_buffer = Echo() writer = csv.writer(pseudo_buffer) response = StreamingHttpResponse((writer.writerow(row) for row in rows), content_type="text/csv") response['Content-Disposition'] = 'attachment; filename="somefilename.csv"' return response It works great. However, I can't find anything that can be done for PDF. Can it? I use render_to_pdf as well as I use a template for PDF.
