how to fetch data from a list of dictionary using django
I am trying to develop a dictionary(using django) that contains a voice for pronunciation. everything goes fine but I cannot relate the audio with the word using the following query. Model.py class Warehouse(models.Model): word = models.CharField(max_length=200, blank=True) type = models.CharField(max_length=200, blank=True) gender = models.CharField(max_length=200, blank=True) meaning = models.TextField(max_length=2000, blank=True) synonyms = models.CharField(max_length=200, blank=True) antonyms = models.CharField(max_length=200, blank=True) usage = models.TextField(max_length=2000, blank=True) class Audio(models.Model): warehouse = models.ForeignKey(Warehouse, on_delete=models.CASCADE) audio_file = models.FileField(upload_to='audio') def __str__(self): return self.warehouse.word def delete_media(self): os.remove(path=MEDIA_ROOT + '/' + str(self.audio_file)) query.py def get_words_warehouse_matching(search_sting): try: dictionary_object = Warehouse.objects.filter(Q(word__icontains = search_sting)|Q(type__icontains=search_sting) | Q(gender__icontains=search_sting)|Q(synonyms__icontains=search_sting)|Q(antonyms__icontains=search_sting) words_list = [] for words in dictionary_object.iterator(): word_dictionary = {'id':words.id, 'word': words.word, 'meaning': words.meaning, 'synonyms': words.synonyms,'antonyms': words.antonyms} words_list.append(word_dictionary) return words_list views.py def search(request): context = {} warehouse={} if request.method == 'POST': context['data'] = get_words_by_matching(request.POST['searchString']) context['warehouse'] = get_words_warehouse_matching(request.POST['searchString']) voice = Audio.objects.filter(warehouse_id = warehouse.id) context['audio'] = voice return render(request, 'dictionary/word.html', context) I need to display the related audio file in the template so that I need to equate warehouse_id to Warehouse.id. How can I fetch the id from get_words_warehouse_matching (dictionary) so that I could use filter(warehouse_id = warehouse.id) in views. Or if there are any other better options, suggestions would be highly appreciated. Thanks in advance. -

Passing a variable vs a hard-coded string is not working on query search using Django shortcuts
I'm in the process of learning how to use Django. My goal is to grab an object (one hero and one villain) from the database using the names, (not id), passed in the URL as search params. I am successfully grabbing the values from the query params, however, when I try to pass the variable "hero" into the Django shortcut, (get_object_or_404(Super,name=hero)), I get a 'not found'. It works fine if I manually type out the string I'm searching for(get_object_or_404(Super,name="Bat Man")). Any ideas why this is and how I can make my query search dynamic by name? @api_view(['GET', 'POST']) def supers_list(request): type = request.query_params.get('type') hero = request.query_params.get('hero') villain = request.query_params.get('villain') if request.method == 'GET': supers = Super.objects.all() if type: supers = supers.filter(super_type_id__type = type) serializer = SuperSerializer(supers, many=True) return Response(serializer.data) elif hero and villain: # print(hero) result is "Bat Man" hero_found = get_object_or_404(Super,name=hero) # hero_found = get_object_or_404(Super,name="Bat Man") print('=====', hero_found) return Response('hello') else: heros = supers.filter(super_type_id__type = 'hero') villains = supers.filter(super_type_id__type = 'villain') heros = SuperSerializer(heros, many=True) villains = SuperSerializer(villains, many=True) result = {'heros':heros.data, 'villains':villains.data} return Response(result) -

Apache/mod_wsgi log object issues upon importing some module
I have a Django application that runs on an Apache server, Ubuntu OS. I've recently added a new import statement of some module, that causes the following server error: File "/dataco_monitor/dataco_venv/lib/python3.7/site-packages/nebula/consts.py" in <module> 49. _is_interactive = os.isatty(sys.stdout.fileno()) Exception Type: OSError at / Exception Value: Apache/mod_wsgi log object is not associated with a file descriptor. I've tried to reproduce the issue by running the app's virtualenv (with the user that runs the server) and importing that module, but got nothing, all good. Also tried to run manually: os.isatty(sys.stdout.fileno()) , it returns 'True'. I've tried to search Google for this issue, haven't found any similar case. What can that be? Any input here will be much appreciated. Thanks -

User Data Posted to Django User Model API Fails Authentication
I have two deployed Django projects: A and B and both have User models for user authentication. But I want users of Project B who sign up to have accounts on Project A as well. So I created an API using DRF for the user model in Project A and I was able to post user data (username and password) from Project B to the API. But when I tried to login to Project A using the newly posted user data, it failed authentication, despite the data now bring present in Project A's API. Please could anyone help me identify what's wrong? I'd love to post code snippets but, cuz of the data, can't really do that, but based on the principle, what do you guys think the problem might be? -

async messages in admin
I created a task in the admin that is costly and should be carried out asynchronously. I would do something like def costly_task(**kwargs): def do_task(id): ## do stuff, you know, that is costly task = ThreadTask.objects.get(pk = id) task.is_done = True task.save() task = ThreadTask() task.save() t = threading.Thread(target = do_task, args = [task.id]) t.setDaemon(True) t.start() return {"id": task.id} With a models.py table: class ThreadTask(models.Model): task = models.CharField(max_length = 30, blank = True, null = True) is_done = models.BooleanField(blank = False, default = False) This works well, but I want to inform the admin of the runnig task, and also when it is finished. There is a very old (django 4.0 incompatible) package called django-async-messages which leverages the normal django-messages package to be used asynchronously. I googled but did not find anything of newer age ... any ideas on how to do this? Can I use djangos async processes to send out two messages: when task started (that one is easy) when task finished Django async send notifications -
