HTMX websockets with Django channels
I try to connect a Django channels Consumer to a HTMX ext-ws element, but I can't get a step further. class MessageConsumer(WebsocketConsumer): def connect(self): self.accept() print("connect") self.send( "type": "websocket.send", "text": "<div id='message'>Hi!</div>" ) ... <head> ... <script src="{% static 'common/js/htmx/htmx.min.js' %}" defer></script> <script src="{% static 'common/js/htmx/ext/ws.js' %}" defer></script> ... </head> ... The HTMX.js and the ws.ss gets loaded correctly at the client's browser. <div id="messages-container" hx-ws="connect:/ws/messages/" {# hx-ext="ws" ws-connect="/ws/messages/" does not work at all #} > <div id="message"></div> </div> If I use the old HTMX-builtin hx-ws method, at least the websocket connects. But I can't get a message to the HTMX element (I thought the #message div should be replaced). If I use the new-style (HTMX extension) syntax (hx-ext="ws" ws-connect...) Can anyone point me to the right direction? -

Smartcard authentication using Django
Is there a way to enable CAC authentication with Django? I've been looking at articles stating to use OpenSSL, pkcs11, etc, but no clue on how to actually get python to parse x509 certificates. Goal is to be able to authenticate users via their smart cards on a custom django web server i'm building out. So far, I've gotten it to work locally by using bash pkcs11-tool to parse cac certs, but no clue on how to do this server-side if a user was to browse to my webserver to be prompted for a cac cert. hope this makes sense. -
create multiple workbooks with xlsxwriter in Django/Python
I am in the middle of a reporting function which will break up reports into different workbooks then zip the files and send them out to users. At this time, I get a successful book for the second iteration, but the first iteration seems to be overridden/lost when the bytesIO object reinitializes on subsequent iterations. def runPullReports(): sharedOrderFxs.sendEmail([], 'Starting..', "Running") start = datetime.date(2022, 7, 7) #now start += datetime.timedelta(2)#running sunday means we've already run tuesday labels dateList = [start + datetime.timedelta(days=x) for x in range(4)] food_programs = list(refModels.FoodProgram.objects.all().values_list('id', flat=True)) pack_list = ['HOT PACK', 'COLD PACK'] workBookList = [] SA = refModels.ServiceArea.objects.all() for service_area in SA: fileName = str(service_area.name) + '.xlsx' output = BytesIO() ## Other Processing here irrelevant to the question book.close() output.seek(0) # resetting BytesIO() buffer before we add workbooks to the list, since we're using BytesIO again in the generate_zip function workBookList.append((fileName, output)) archive = generate_zip(workBookList) dateRange = f'{dateList[0].month}-{dateList[0].day}_{dateList[-1]}' #email send fnx sending archive.

Handling static files and venv during deployment to AWS EB
I have my Django project up static files set-up like this: STATIC_ROOT = BASE_DIR / 'static' STATICFILES_DIRS = [(BASE_DIR / 'staticfiles'), ] I add static to .gitignore, this way I put my files in staticfiles folder and upload them to git. And on the deployment server I run collectstatic to move them to the static folder. This worked ok until I decided to move the project to AWS EB. Because I have to run collectstatic before eb deploy it ignores my static folder during deployment (since it is in .gitignore). A solution I used before was adding .ebignore with staticfiles in it instead of static. Only with this project it throws an error: An error occurred during execution of command [app-deploy] - [StageApplication]. Stop running the command. Error: chown /var/app/staging/ve/lib64: no such file or directory From what I've read it has something to do with simlinks in aws cli that were created for my venv folder ve. But I can't find a fix for it. So I have two questions: What is the proper way to handle static files with Django? How to remove venv folder from eb? -
Django email contact me form
So I'm working on this django web app and I want to create a contact me form for my client. My client wants the users of his website to be able to send him emails directly from the form available on the platform. But my client uses a free yahoo email address. I'm kind of confused of where to begin. But here is my suggested approach see if you can give me an advice: 1- create a form in the forms.py with the different fields of the form. 2 - link the form to the template. 3- create the view for the contact form. 4- add the path in the url pattern. I read an article that says I need to go through an email service like SendGrid to actually send an email. But it said that I need a professional account to be able to do it. I really appreciate your attention. -

Publishing Django project in EC2 AWS instance
I am trying to publish a Django Web page in an instance of AWS. I have configured the EC2 instance based on Windows machine, with elastic IP to get a fixed public IP. However, when I try to run the Django project, I can only assign the private IP. In this case, if, after running the project, I try to access the Web from the public IP, I cannot access the Web site (just an error message from the browser warning about the impossibility to access the site). Below, the two snapshots of the execution. While the first one shows how with the private IP it works, the second one depicts the error I am receiving. I have tried with the 0:8000, but also with <public_IP>:8000 without success. In the case of setting the public IP, I got Error: That IP address can't be assigned to. Last but not least, in the settings.py file, I have included ALLOWED_HOSTS = ['*']. Could you let me know how to proceed, please? Many thanks in advance. -
Nginx and Django/Wagtail : Origin checking failed - null does not match any trusted origins
When i try to log on my admin page in wagtail, i get this error. My settings.py has this line : CSRF_TRUSTED_ORIGINS = ["http://localhost","http://domain","http://server_ip","https://localhost","https://domain","https://server_ip"] Where server_ip is my ip and domain is my domain. However the error message might to be dealing with nginx : the origin is not present in the request as django finds null as origin. I have a reverse_proxy set in nginx as follows: location /api { proxy_pass http://backend:8000/api; proxy_set_header Host $host; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 20M; } What can I add so django finds a correct origin? -
Django Friends all declined
I am trying to add friends in a django app and I try to do it with this way. I created a new table named Friends where there is no foreign key. It looks like this: class Friends(models.Model): name = models.CharField(max_length=200) hisname = models.CharField(max_length=200) answer = models.CharField(max_length=200) And in the views.py I wrote: def seeit(request,aname): friends = Friends.objects.filter(hisname=aname).all() if request.method == 'POST': for i in friends: if 'accept' in request.POST: request3 = Friends.objects.filter(name=i.name).first() setattr(request3,'answer', 'yes') request3.save() elif 'decline' in request.POST: request2 = Friends.objects.filter(name='5319').first() request2.answer = 'no' request2.save() return render(request,'all.html',{'requests':friends}) In all.html it just shows the friend requests and you can accept or decline it. But when I run it I don't get an error but if for example, I declined a friend request then all of them are declined and if I accept one then all of them are accepted. What should I do? Thanks. -

Why is my url parameter undefined in Django?
I'm trying to pass a url parameter to a Django's generic DeleteView. I've included the parameter in my urls.py, but it still comes back undefined. This is my code: My view in views.py: class Delete(post_id, DeleteView): #error on this line ... Urls.py urlpatterns=[ ... path('delete/<uuid:post_id/', views.delete.as_view(), name='DeleteView'), ... I have no clue what the issue is, as I've passed variables to views before dong this same simple process. I have also tried passing Deleteview first like class Delete(DeleteVew, post_id): but that didn't work either. Thank you for your time. -

django form field displayed out of order
I have this form and model for a group: class GroupForm(forms.ModelForm): class Meta: model = Group fields = ('leader', 'description', 'size', 'max_size', 'motto') widgets = { 'size': forms.CheckboxInput(attrs={'id': 'size'}), 'max_size': forms.TextInput(attrs={'type': 'hidden', 'id': 'maxSize'}), } The creator of the group has an option to check yes for size and on doing so, I used javascript to change the type of max_size to show. In my create_group.html template: <script> let size = document.getElementById('size') let maxSize = document.getElementById('maxSize') let checked = false size.onclick = () => { checked = !checked if (checked === true) { maxSize.type = 'show' } else { maxSize.type = 'hidden' } } </script> Now, this works fine, the only problem is that the fields are displayed out of order. When the page loads, max_size is false and its field is not displayed. Which is good. However, when the user checks that group has a size, and, subsequently, the max_size has a display of show, the field shows up after the motto field and not in its correct order according to fields = ('leader', 'description', 'size', 'max_size', 'motto'). Furthermore, the max_size field is included inside the motto element itself and not as its own field: vs. the other fields … -

How to override admin.ModelAdmin class from site-packages?
i want to override help_text for some model in site-packages. but i obviously can't just change it in package because it will not be saved after updating packages and some other actions. crontab = models.ForeignKey( CrontabSchedule, on_delete=models.CASCADE, null=True, blank=True, verbose_name=_('crontab'), help_text=_('Use one of interval/crontab'), ) probably i have to create some app and override the whole thing in admin.py but i'm not sure it is a good practice. also there is option with localize i consider but i still will have to create an app for that. -
Django materialized view migration problem on update
We are building a library in Django (v4.0) with Postgres (v13). This library is going to be the core for our company, so we have to be careful with the migrations. The problem is with Django migrations when we update the base table for any materialized view.

Running django application via SSH on Windows
This question is related to the testdriven.io series of articles on how to build and deploy your Django application. In detail, my question is relatad to the second article of the three. Everything works fine as we build locally the application with nginx and gunicorn. Then, he uses a linux command ssh user@your-ip-or-domain to connect to the host, which I think might be the name of the domain he suggests to create with freenom.com. Now, I am on a Windows machine and have no idea how to perform this operation that he does not explain (should we copy the project on a virtualbox with linux? should you run an image of linux with docker?). The article I am referring is this in the "Running the Containers" paragraph. I am looking for a deeper explanation of that phase. Thanks a lot. which I do not know how to perform on Windows. -
