Apache - HTTPS with one certificate for two different ports - Only one is accessible at a time
I'm trying to host 2 (different) servers on a single domain. One is hosted on port 8000 and the other on 8080. I want both to be accessible with HTTPS using the same certificate. Below is my conf file (both servers use the exact same configuration, just different ports and names). They both work perfectly in HTTP. However only one of the two is accessible in HTTPS for some reason, the other will load infinitely until timeout. <VirtualHost *:8080> OR <VirtualHost *:8000> ServerAdmin webmaster@localhost ServerName example.stratoserver.net ServerAlias www.example.stratoserver.net DocumentRoot /var/www/st-backend ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /static /var/www/st-backend/static <Directory /var/www/st-backend/static> Require all granted </Directory> Alias /static /var/www/st-backend/media <Directory /var/www/st-backend/media> Require all granted </Directory> <Directory /var/www/st-backend/project> <Files wsgi.py> Require all granted </Files> </Directory> WSGIDaemonProcess st-backend python-home=/var/www/st-backend/stenv python-path=/var/www/st-backend WSGIProcessGroup st-backend WSGIScriptAlias / /var/www/st-backend/project/wsgi.py #HTTPS SSLEngine on Include /etc/letsencrypt/options-ssl-apache.conf SSLCertificateFile /etc/letsencrypt/live/example.stratoserver.net/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/example.stratoserver.net/privkey.pem </VirtualHost> ports.conf Listen 8080 Listen 8000 <IfModule ssl_module> Listen 443 </IfModule> <IfModule mod_gnutls.c> Listen 443 </IfModule> Can anyone point me in the right direction as to why I can't get both working with HTTPS at the same time? I would highly appreciate it. -
DRF NoReverseMatch
I am able to create and save a vote with postman, but when running a unittest with the functionality using reverse, it can't find the URL. I've tried a combination of running this with and without args/kwargs and nothing seems to work. It also appears to be in line with the documentation views.py class EntryViewSet(viewsets.ModelViewSet): @action(detail=True, methods=['post'], permission_classes=[IsAuthenticated]) def vote(self, request, *arg, **kwargs): ... tests.py def test_vote_entry_success(self): self.authenticate_client(self.other_user_data) response = self.client.post(reverse('api:entries-vote'), kwargs={'slug': self.entry.slug}) self.assertEqual(response.status_code, status.HTTP_201_CREATED) error message django.urls.exceptions.NoReverseMatch: Reverse for 'entries-vote' with no arguments not found. 2 pattern(s) tried: ['api/entries/(?P<slug>[^/.]+)/vote\\.(?P<format>[a- z0-9]+)/?$', 'api/entries/(?P<slug>[^/.]+)/vote/$'] I used django-entensions to see map my URLs and the action is showing up as a valid route /api/entries/<slug>/vote/ api.views.EntryViewSet api:entries-vote And the test works when I hard-code the URL response = self.client.post('/api/entries/'+self.entry.slug+'/vote/') -

How do I put ajax on django class based update view
I have two submit buttons in my web-page. One of them is for submitting the form. The other one uses ajax to send the text inside a text-box to the server, processes it and returns back the result (in my case summary of the text) into another text-box. I implemented it using ajax call of this kind: $(document).on('submit','#report-text',function(e){ e.preventDefault(); $.ajax({ type:'POST', url:'{% url "create-post" %}', data: { unsummarized_news : $("#id_news").val(), csrfmiddlewaretoken : $('input[name=csrfmiddlewaretoken]').val(), }, success:function(){ fetch('{% url "create-post" %}', { headers:{ 'Accept': 'application/json', 'X-Requested-With': 'XMLHttpRequest', }, }) .then(response => { return response.json() }) .then(data => { console.log(data) document.getElementById("id_title").value = data['summary']; }) } }) }); This is the view I used, for creating post and ajax call: class CreatePost(LoginRequiredMixin, View): def get(self, request, *args, **kwargs): if request.is_ajax(): data = { 'summary': summary } return JsonResponse(data) form = PostForm() context = { 'form': form, } return render(request, 'posts/create_post.html', context) def post(self, request, *args, **kwargs): if 'news_submit_form' in request.POST: form = PostForm(request.POST, request.FILES) if form.is_valid(): new_post = form.save(commit=False) new_post.publisher = request.user new_post.save() form = PostForm() # Clearing the form after submission if 'unsummarized_news' in request.POST: global summary unsummarized_news = request.POST['unsummarized_news'] summary = get_summary(unsummarized_news) return redirect('home') It works fine when creating a new post. … -
Serving React and Django on Nginx with SSL and Domain/Subdomain
I have a React application and Django application served by Nginx. I would like to find a way to serve React on domain.com and Django on api.domain.com. Additionally, both frontend and backend must use HTTPS so they must be listening on port 443 at the same time. Right now, I have an SSL certificate for the frontend. Will changing the server_name for the frontend to domain.com and the backend to api.domain.com be enough to handle my requirements? Is this a better configuration than having my API be served under domain.com/api/?

Why my django project's send_mail isn't working properly?
I was creating a project in which the website will automatically send the emails to the member who's last date of bill payment is today. To do so I created a method in the model class of Entry in my django project. I have fully configured the smtp settings in project/settings.py .

Using django filer
I want to be able to reuse the same image and I found that django-filer is perfectly what I was looking for. But, I didn't find any documentation or tutorial about how to use this package (move from basic ImageField to django filer). The documentation is only explaining about how to use it on fresh new projects. This is the best link about explaining how to use django-filer https://wellfire.co/learn/migrating-to-django-filer/. But it lacks detail in the explanation and I found an error while trying it. One more question. I want to use django-filer only in admin (only admin who can reuse the same image). But I also have form for the basic users. I want to use the basic upload image field in the form so the basic user doesn't have the "reuse image" feature. Is there any solution for this? or is there any better package that is similar to django filer? -
Python Flask - How to download a file with send_from_directory AND display text output in browser

Is there a way to achieve this? If I wasn't using send_from_directory, I could do something like this to return some JSON return {'Status': 'file download triggered'} I'm looking for a way to combine the two, that way the user doesn't see a blank screen when they hit this endpoint. -

AWS Elastic Beanstalk RDS MacOS mysqlclient not working

When I deploy, I have problems.

Isn't yum for use on operating systems other than MacOS? I followed the instructions here: https://pypi.org/project/mysqlclient/ And of course mysqlclient is in my requirements.txt Obviously I need the files mentioned above, but how do I get them? -
Django - After Register, Data Should Go To 2 Different Tables (Customer & User)
I am creating an e-commerce website where people can choose to login or not but still the can order and checkout (even if you are an AnonymousUser or Guest user). Now, I am making a login and register form in my website. The login form works and looks good but the register form wasn't working and throwing an error that said "RelatedObjectDoesNotExist at / User has no customer." I think the reason is that when I register, it only makes a User in database but didn't register anything in the Customer table (which consists Name and Email). How can I register a Customer and User at the same time when I hit the "Submit" button? And how can I make that specific User have "Staff status" only and cannot make changes in the Admin site? Also, I want to add new fields in the Register form for Name and Email that will go directly to the Customer table. I tried to do this one but it doesn't work and throwed and error that says "django.core.exceptions.FieldError: Unknown field(s) (name) specified for User". Here's what I did: from django.forms import ModelForm from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm from .models import … -
How can I deal with too many open file descriptors in Python/Django?
My Django app has multiple models that have some file fields: class MyModelA(models.Model): field1 = models.FileField(...) field2 = models.FileField(...) field3 = models.FileField(...) class MyModelB(models.Model): field1 = models.FileField(...) field2 = models.FileField(...) field3 = models.FileField(...) In order to generate some test data for my app that includes fake files, I do this: my_app/management/commands/generatetestdata.py: class Command(BaseCommand): def handle(self, *args, **options): self.generate_model_a_test_data() self.generate_model_b_test_data() ... def generate_model_a_test_data(self): field1_data = Path("/path/to/field1/sample/file").read_bytes() field2_data = Path("/path/to/field2/sample/file").read_bytes() for _ in range(1000): instances = [] instances.append(MyModelA( field1=ContentFile(field1_data, name="Some File Name"), field2=ContentFile(field2_data, name="Some File Name"), )) MyModelA.objects.bulk_create(instances) That's not the exact code I use, but that's the idea. There are only a few actual files that I'm reading off the filesystem. I read them into memory, and create a ton of ContentFile instances, which, when saved, actually copies those files to my media directory. Yes, not as efficient as using something like symlinks, but that's fine. The problem I'm seeing is that sometimes, running python manage.py generatetestdata succeeds, while other times, it fails after several minutes with: django.db.utils.OperationalError: unable to open database file When it does fail, it's after creating thousands of files (NOT immediately after running the command), so it's definitely not a permissions issue.

django ajax get model data in JS variable
Trying to get my model data from django views.py in home.html javascript variable using AJAX. So far I'm at : Views.py: def flights_list(request): flights = serializers.serialize("json", Flights.objects.all()) return JsonResponse({"flights": flights}) Ajax: function get_data() { $.ajax({ url: '', //Not sure what to put here. datatype: 'json', type: 'GET', success: function (data) { alert("Got data!") locations = {{ flights }}; } }); }; $(document).ready(function(){ setInterval(get_data,5000); }); Every 5 seconds i'm getting alert "Got data!" But when I'm trying to pass variable location = {{ flights }}; Then locations is empty. in ajax url:'' i suppose to have my views.py location? as when trying to alert("Got data!" + data) then my whole html is in that data variable.. Am i doing something wrong here?
