Redirect django admin panel to appropriate path in the docker
I have a docker-compose.yaml script. I want proxy to pass the Nginx in this to another host-level nginx whose config as follows server { listen 80; server_name donorgrid.tbhaxor.com _; error_log /var/log/nginx/donorgrid.error.log; access_log /var/log/nginx/donorgrid.access.log; location /management { proxy_pass http://localhost:8080/; } } I want my base URL to be https://donorgrid.tbhaxor.com/management/ and all users inherit this. For example, admin panel should be available on https://donorgrid.tbhaxor.com/management/admin With this configuration, I am getting issues in redirection as Django sends redirect response with Location header /admin/ which in this case doesn't exist. Here are my curl request and responses # curl -I donorgrid.tbhaxor.com/management HTTP/1.1 302 Found Location: /admin/ # curl -I donorgrid.tbhaxor.com/management/ HTTP/1.1 404 Not Found # curl -I donorgrid.tbhaxor.com/management/admin HTTP/1.1 404 Not Found Note: I have stripped out unwanted headers for this question -

Switching django app to apache, Permission denied: mod_wsgi
I've developed a django app which works properly with python3-venv through django 'server:8000' on Ubuntu 21.04.

Adding label to Django AppConfig gives error with migrations
I am new with Django. I am using DRF. I was trying to integrate social authentication using dj-rest-framework and django-allauth, but I currently have an app called account, so it gives a naming conflict with allauth.account. I managed to fix this by following this solution. It is a known problem with allauth.account and changing one of the apps label will fix the confilct. Here comes the second problem. After I configured the URL, it gave an error ProgrammingError "Table '<project-name>.socialaccount_socialapp' doesn't exist" So, I thought that maybe making migrations will fix the issue. When I try making migrations, it gave some different errors based on the changes that I made, but none of the solutions seems to work. When I changed the label name of the AllAuth Account as described on the solution mentioned above and then trying to make the migrations python manage.py makemigrations gives this error: CommandError: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0001_initial, 0002_email_max_length in allauth_account). To fix them run 'python manage.py makemigrations --merge' and then running: python manage.py makemigrations --merge gives ValueError: Could not find common ancestor of ['0001_initial', '0002_email_max_length'] If I try changing my account app label instead of the allauth … -

Get most liked post in last 10 days in django
I am building a BlogApp and I am trying to get most liked blogpost in last 10 days. Then after 10 days, new most liked posts will be shown. BUT when i try to access then is not showing. models.py class BlogPost(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=30) date_added = models.DateTimeField() likes = models.ManyToManyField(User, related_name='blogpost_dislike', blank=True) views.py def blogposts(request): time = timezone.now() - timedelta(days=10) liked = BlogPost.objects.annotate( num_likes=Count('likes')).filter( num_likes__gt=10).filter(date_added__gte=time) BUT the above code will show posts which have more than 10 likes . BUT i am trying to show most liked(without minimum) in 10 days. What have i tried :- I also tried this in template tag :- @register.simple_tag def get_most_commented_posts(count=10): return BlogPost.objects.annotate( total_likes=Count('likes') ).order_by('-total_likes')[:count] This code is also checking minimum 10 likes in posts. Then i tried this liked = BlogPost.objects.annotate(total_likes=Count('likes')).filter(date_added__lte=time) BUT this is not even filtering, it is showing all the posts. AND I am trying to get most liked posts in last 10 days. Any help would be Appreciated. Thank You in Advance. -
How can I delete specific row instead of always the first row (Modal in Django)
I'm building a CRM app and try to delete a specific client when the confirmation button is clicked in the pop-up modal, but it always deletes the first client. I know that it happened due to the ambiguous class name, and the problem may be solved by adding a unique id for each client? I have been searching around for this type of problem but still not sure how to solve it. Since I generated every client by a for loop and I might need to dynamically create a unique id for each client and call the specific id in javascript and modify the corresponding CSS? I feel that this way might be over-complicated. Are there any other methods to achieve my goal? Thanks. My code is following: Templates <!-- client table --> {% for user in clients %} <tr class="mt-3"> <td class="pt-3">{{ user.level }}</td> <td class="pt-3"><a href="{% url 'clients' user.id %}">{{ user.first_name }}</a></td> <td class="pt-3">{{ user.last_name }}</td> <td class="pt-3">{{ user.country }}</td> <td class="pt-3">{{ user.contact }}</td> <td class="pt-3">{{ user.contact_number }}</td> <!-- <td><a href="#" class="btn btn-outline-primary btn-sm">Client Info</a> --> <td><a href="{% url 'update' user.id %}" class="btn btn-outline-warning">Update</a> <a class="btn btn-outline-danger" onclick="clientmodal()" >Delete</a></td> </tr> <!-- client modals --> <div class="modal-bg"> <div class="delete-modal"> … -
Append server name in a API response -- Django rest framework
I have been trying to create a API with Django restframework. There is a Image field in the API which is giving a relative path. I would like to have absolute path or name of the server to append before the Image field. But its throwing an error TypeError: string indices must be integers I believe the json that I created from the ordered dict is a string and is not giving expected output. Problem: I need to access the json keys and append server name in it. I tried the following for it. views.py def get_individualmember_details(request): if request.method == 'GET': serializer = MasterIndividualMembersSerializer(MasterIndividualMembers.objects.all(), many=True) result = json.dumps(serializer.data) print(result) for row in result: if row["member_photos"]["image"]: row["member_photos"]["image"] = request.META['HTTP_HOST'] + "/" + row["member_photos"]["image"] result = json.dumps(result) return JsonResponse(json.loads(result), safe=False) expected output: [ { "model": "userdata.masterexecutivemember", "pk": 1, "fields": { "firstname": "John", "lastname": "Doe", "profile_image": "http://127.0.0.1:8000/user/1.jpeg", //Needs to append servername here "description1": "Test abc", } }, ... ... ] Please suggest how to append the server name or a string before any json key.

How can I trigger a Bootstrap modal programmatically when a Django template condition is met?
Let's say one of the views returns a context with the key 'db_busy' with a String if someone is using the database. Django part: def check_status(request): context = { 'current_tab': '1' } if request.method == 'POST': if get_lock_data(): lock_data = get_lock_data() for x in lock_data: if x['user_name'] != request.user.username: context['db_busy'] = 'Warning! The database is in use by: '+x['user_name'] return render(request, 'index.html', context) So what I want in index.html is, first of all, to check if that key (db_busy) exists in the context, if it exists that means that another user is modifying the database and therefore I want to show an informative modal. What I've tried so far: Javascript part within index.html (truncated index.html): <script> $(document).ready(function(){ $('[data-toggle="tooltip"]').tooltip(); }); {% if db_busy %} alert("{{db_busy}}"); $('#dbBusyModal').modal('show'); {% endif %} </script> The alert is working properly and showing up as expected when some user is editing the db. But for some reason, the modal is not showing. modal code (truncated index.html): <!-- Modal --> <div class="modal" id="dbBusyModal" tabindex="-1" role="dialog"> <div class="modal-dialog modal-dialog-centered modal-sm" style="width:350px;" role="document"> <div class="modal-content"> <div class="modal-header"> <h4 class="modal-title">Warning!</h4> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div class="modal-body"> <p>Warning!
