Django exported csv rows values changed with commas
I have a website that has some radio buttons that depending on which one you click it downloads one database table or another. I have made a Django view and then an Ajax function in Javascript. For some reason when I select one of the radio buttons and hit the download button, all the values of the csv are changed with something like ",,,,,". Does anyone know why this happens? My views.py: def download_db(request, mode): #data = JSONParser().parse(request) #serializer = WordsTableSerializer(data=data) response = HttpResponse(content_type='text/csv') writer = csv.writer(response) if mode == 1: writer.writerow(['session_id', 'word1', 'word2', 'word3','distance_to_word12','distance_to_word13', 'distance_to_word23']) for word in WordDifferentTable.objects.all().values_list('session_id', 'word1', 'word2', 'word3', 'distance_to_word12', 'distance_to_word13', 'distance_to_word23'): writer.writerow(word) response['Content-Disposition'] = 'attachment; filename="WordsDifferent.csv"' return response elif mode == 2: writer.writerow(['session_id', 'word1', 'word2', 'word3', 'distance_to_word12', 'distance_to_word13', 'distance_to_word23']) for word in LogicAnaloguiesTable.objects.all().values_list('session_id', 'word1', 'word2', 'word3', 'distance_to_word12', 'distance_to_word13', 'distance_to_word23'): writer.writerow(word) response['Content-Disposition'] = 'attachment; filename="ForLogicAnalogies.csv"' return response elif mode == 3: writer.writerow(['session_id', 'word1', 'word2', 'word3', 'distance_to_word12', 'distance_to_word13', 'distance_to_word23']) for word in SimilarWInContextTable.objects.all().values_list('session_id', 'word1', 'word2', 'word3', 'distance_to_word12', 'distance_to_word13', 'distance_to_word23'): writer.writerow(word) response['Content-Disposition'] = 'attachment; filename="ForSimilarWordInContext.csv"' return response elif mode == 0: writer.writerow(['session_id', 'word1', 'word2', 'word3']) for word in WordsTable.objects.all().values_list('session_id', 'word1', 'word2', 'word3'): writer.writerow(word) response['Content-Disposition'] = 'attachment; filename="WordsTable.csv"' return response return JsonResponse({}, status=304) The Ajax function: $( "#downloadbtn" ).click(function() … -
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process (Python/Django)
I know this question has been asked quite a bit on here, however after trying a number of solutions I am unable to figure out how to fix this issue. I am downloading images from the Google Maps API to generate maps with and without markers. I am using django-cleanup to remove files when deleted from database however the old versions wont delete. Weirdly, django-cleanup works correctly and deletes the associated image when deleting from the Django Admin page but not when deleting the file directly i.e. in file explorer and says it is open in Python. It also deletes correctly when my local server is terminated as you would expect. Traceback is as follows: Traceback (most recent call last): File "C:\Users\Ricki.Demmery\Desktop\dev\acl_acousticapp\env\lib\site-packages\django_cleanup\handlers.py", line 97, in run_on_commit file_.delete(save=False) File "C:\Users\Ricki.Demmery\Desktop\dev\acl_acousticapp\env\lib\site-packages\django\db\models\fields\files.py", line 373, in delete super().delete(save) File "C:\Users\Ricki.Demmery\Desktop\dev\acl_acousticapp\env\lib\site-packages\django\db\models\fields\files.py", line 105, in delete self.storage.delete(self.name) File "C:\Users\Ricki.Demmery\Desktop\dev\acl_acousticapp\env\lib\site-packages\django\core\files\storage.py", line 304, in delete os.remove(name) PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\Ricki.Demmery\\Desktop\\dev\\acl_acousticapp\\src\\acl_ac ousticapp\\media\\projects\\9335\\gmaps_markers_5xDqMnc.png' The call in views.py is as follows: gmaps = GoogleMapsAPI() gmaps.location_img(prjID) My Google Maps class def create_styled_marker(style_options={},mkr_lat=0,mkr_lng=0): opts = ["%s:%s" % (k, v) for k, v in style_options.items()] return '|'.join(opts) + '|{mkr_lat},{mkr_lng}|'.format(mkr_lat=mkr_lat, mkr_lng=mkr_lng) … -
Django app on Google App Engine slows down after 15 requests
I deployed a Django app on Google App Engine Standard with a F4 machine. The API is doing some machine learning and the processing has a duration of around 4s in local (between 3.5 and 4s). For my use case, it would be ok to have also 4-5s delays with the deployed app. However, when I test the deployed app doing the same request multiple times, I saw that the first requests take 3-4 seconds, but after 10-15 iterations, they take around 8s. Here is the code I used to test my app: session = requests.Session() all_times = [] for i in range(50): try: t0 = time.time() resp = session.post(url_api, headers=headers, json=data) t1 = time.time() print(t1 - t0) all_times.append(t1 - t0) except Exception as e: print("Err", e) The results of the request durations are as follows: I wonder why there is this gap after 15 requests and why some points are way above the average 7-8s (e.g. 10s). I get the same pattern looking at the latency in the Google Cloud Console: What I tried I tried to change the autoscaling parameters, thinking that it could be because of the creation of instances. But I got the same pattern when … -

Can anybody help me. I want to know if there is a good solution to moving a large amount of data filtered from one table in an oracle db to another in a mysql db.

how to make my trigger function to perform asyncronously to update tsvector field?
I am new to postgres. Suppose i have two models AnimalType and Animal. And i have search_vector field of type tsvector in Animal model. i created trigger that whenever i update a AnimalType row, the searchvector should update itself for every Animal related to that AnimalType. CREATE OR REPLACE FUNCTION update_animal_type() RETURNS TRIGGER LANGUAGE plpgsql AS $$ BEGIN UPDATE animal SET search_vector = NULL WHERE animal_type_id = NEW.id; RETURN NEW; END; $$; CREATE TRIGGER animal_type_update_trigger AFTER UPDATE OF animal_type_name ON animal_type FOR EACH ROW EXECUTE PROCEDURE update_animal_type(); It takes a lot of time to update a single animal type row when we have large number of animals related to that particular animal type. Is this behaviour is synchronous or asynchronous? If it is synchronous how can i make it to behave asynchronous? -

After dropping database, I am getting this ModuleNotFoundError: No module named 'myproject' error
I ran into a database out of sync error and so I dropped one database in development mode and synced my settings to a newly created postgresql database. I removed my pycache and migrations prior to creating a new database and then ran the "python3 manage.py makemigrations" and "python3 manage.py migrate". Here is a link to the prior error and code if that's necessary to know. django.db.utils.ProgrammingError: column accounts_account.username does not exist However, when I ran "python3 manage.py createsuperuser" it gave me this ModuleNotFoundError: No module named 'myproject' error.

Make django parent model accessible to formset without displaying it in html
I have page1 with two links (‘A’ and ‘B’) on it the specific link that is clicked determines a query parameter /page2/?q=A or /page2/?q=B. On page 2 the user completes an inline formset, the parent form of which has been set to a value of ‘A’ or ‘B’ depending on the link clicked on the previous page. I do not want to display the parent form but if this is not displayed then I am unable to successfully save the formset and parent form. The views.py for page 2 is: class CaseView(TemplateView): model = Case template_name = “page2/page2.html” def get(self, *args, **kwargs): # parent form case_form = CaseForm # child formset sideeffect_formset = SideeffectFormSet(queryset=SideEffect.objects.none()) return self.render_to_response( { "case_form": case_form, "sideeffect_formset": sideeffect_formset, "sideeffect_formsethelper": SideEffectFormSetSetHelper, } ) def post(self, *args, **kwargs): form = CaseForm(data=self.request.POST) sideeffect_formset = SideeffectFormSet(data=self.request.POST) if form.is_valid(): case_instance = form.save(commit=False) if self.request.user.is_authenticated: case_instance.user = self.request.user case_instance.save() if sideeffect_formset.is_valid(): sideeffect_name = sideeffect_formset.save(commit=False) for sideeffect in sideeffect_name: sideeffect.case = case_instance sideeffect.save() return redirect( reverse( "results", kwargs={"case_id": case_instance.case_id}, ) ) I want to be able to save CaseForm and have it available for the childformset without actually displaying CaseForm in the html -
