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. Thanks in advance! -
Why response is always {"detail":"Unsupported media type \"text/plain\" in request."} in swift?
I have created a sample app in Django which deletes a question from App. And provides a correct output when consumed using POSTMAN. class Questions(APIView): def delete(self,request): received_id = request.POST["id"] print(received_id) place = Question.objects.get(pk=received_id) place.delete() questions = Question.objects.all() seriliazer = QuestionSerializer(questions,many = True) return Response({'Orgs': seriliazer.data}) However, when I am trying to achieve it from iOS app, it's returning {"detail":"Unsupported media type "text/plain" in request."} func deleteQuestion( id: Int){ guard let url = URL(string: "http://127.0.0.1:8000/V1/API/questions/") else { return } var request = URLRequest(url: url) let postString = "id=15" request.httpBody = postString.data(using: String.Encoding.utf8); request.httpMethod = "DELETE" URLSession.shared.dataTask(with: request) { data, response, error in let str = String(decoding: data!, as: UTF8.self) print(str) if error == nil { self.fetcOrganizatinData() } }.resume() } Could not really understand where exactly the problem is ? -

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!

Under Django concurrency, why does the generated snowflake ID repeat?
I use modules written by others, as follows: https://github.com/tarzanjw/pysnowflake/blob/master/snowflake/server/generator.py I first ran a single-threaded test by myself. There will be no duplication at all, and there is no duplication at all when multi-threaded locks are added. But when I generate it in the actual project with Django, about 10 Threads submit a total of 1600 pieces of data, and about dozens of duplicates will be generated each time I printed the ID, and this snowflake generator instance has not been initialized. How can I troubleshoot? The approximate code is as follows: from newsnow import Generator logger = logging.getLogger('django-production') get_flake_id = Generator(dc=0, worker=0) def create_product_meta(prepare_product_meta): new_product = models.productMeta( own_store=prepare_product_meta.get("own_store").upper(), product_name=prepare_product_meta.get("product_name"), ) logger.warning(id(get_flake_id)) new_product.flake_id = get_flake_id.get_next_id() return new_product Any suggestions? thanks! -

Django Admin hiding objects
I have an auto-created Admin via admin.site.register(MyModel) But some of my MyModel entries are missing. This happens when I set a field called active to False, but active is a field defined by me. Why would setting active to False hide my items from django admin? One clue would be that I'm using a custom manager, but I'm not sure why this would matter given that I don't filter on this in admin. class MyModel(models.Model): ... active = models.BooleanField() objects = models.Manager() active_objects = ActiveManager() class ActiveManager(models.Manager): def get_queryset(self): return super().get_queryset().filter(active=True) -

How to integrate Facebook Login in django-graphql-jwt?
We have a django project that uses the Graphene-Django library to implement a GraphQL API in our project. This backend is accessed by our mobile apps. For the authentication of the apps, we use the django-graphql-jwt library, which is a JSON Web Token library in Django with GraphQL approach. Now we want to implement the Facebook Login in our system and with it the authentication happens in Facebook. After authentication, what will be sent to our backend from the mobile app is only the email of the user. How can I register and authenticate the user in django-graphql-jwt without the password? Or is there a better workflow for this?
