Write and read video download progress into session
Outside of Django views, I have a function that downloads some YouTube video with pytube library. For tracking the download progress, I am leveraging the pytube's YouTube class on_progress_callback parameter: yt =YouTube(url, on_progress_callback=write_download_progress) write_download_progress is as follows: def write_download_progress(stream, chunk, file_handle, bytes_remaining): filesize = stream.filesize progress = (100*(filesize - bytes_remaining))/filesize progress = round(progress) url = 'http://127.0.0.1:8000/write_download_progress' params = {'progress': progress} try: response = requests.get(url, params) except: # ignore error caused by too frequent requests pass As you can see, as the download progresses, a request is being made to write_download_progress view, which purpose is to write the progress into session: def write_download_progress(request): progress = request.GET.get('progress', 'Error getting progress!') request.session['progress'] = progress print('WRITE ' + str(request.session['progress'])) return JsonResponse({'progress':'{}% downloaded...'.format(progress)}) I also have another view to read the progress from session, which is being called by the front end at two second interval just before the download starts: def read_download_progress(request): progress = str(request.session.get('progress', 0)) print('READ ' + progress) return JsonResponse({'progress': progress}) The print in the writing view will print correct progress values. However, the print in the reading view (and as a result - the view's JSON response) will always be zero. What might be the reason? Is there a better way … -

In Python, how do I force "datetime.strptim" to use a timezone?
I'm using Django and Python 3.7. I'm parsing some strings into dates using this logic ... created_on = datetime.strptime(created_on_txt, '%Y-%m-%dT%H:%M:%S+00:00') print(created_on.tzinfo) How do I incorporate the fact that the time zone I want to be interpreted for the string shoudl be UTC? When I print out the ".tzinfo," it reads "None." An example of something I'm parsing is 2019-04-08T17:03:00+00:00 -
Installing Django wagtail apps in ubuntu and conflict with version

Filter an object with a many to many relation, checking if it contains at least one of the elements in a list
We're making an app that will be used to sell second-hand items. Inside of this app, we'll have an option to filter products based on a series of criteria: the user's geographical postion and a maximum distance, a minimum price, a maximum price, a minimum score, and a list of tags. My main problem is filtering the many to many relationship that a product has with a tag. What we want to do is get all the products which contain at least one of the tags selected by the user. Here's the code for the filter function: def FilterProduct(request, format=None): if request.method != 'POST': return Response(status=status.HTTP_400_BAD_REQUEST) token = request.POST.get('token', 'nothing') if token == 'nothing': return Response(status=status.HTTP_400_BAD_REQUEST) else: try: tags = request.POST.get('tags', '') tags_pk = [] for tag_search in tags: tag = Tag.objects.filter(nombre=tag_search) if tag != None: tags_pk.append(tag.pk) user_latitude = request.POST.get('latitud', '') user_longitude = request.POST.get('longitud', '') max_distance = request.POST.get('distancia_maxima', '') min_price = request.POST.get('precio_minimo', '') max_price = request.POST.get('precio_maximo', '') min_score = request.POST.get('calificacion_minima', '') if tags == '' or user_latitude == '' or user_longitude == '' or max_distance == '' or min_price == '' or max_price == '' or min_score == '': return Response(status=status.HTTP_400_BAD_REQUEST) products = Productos.objects.filter(precio__lte=max_price, precio__gte=min_price, vendido_por__media_valoraciones__gte=min_score, tiene_tags__in=tags_pk) For some reason, … -
Email verification from db
I am having a webapp in django . I tried using the tokengenerator for password reset to create a verification mail, it's not activating the email . coming to the problem , While the user provide email , it should check whether email is present in the db (db will be updated with user emails ) After verifying whether email is present in the db , user is prompted to create password 3.After creating password user can login to the respective page Is there any solution ? I tried and followed https://medium.com/@frfahim/django-registration-with-confirmation-email-bb5da011e4ef Above post helped me to send the email , but the user is not activate after verifying the email , the post doesn't meet my requirement , though i tried to check whether email verification is possible. Is there any third party module for django or any solution for the requirements i have mentioned. -
Django - how to visualise signals and save overrides?
When project is getting bigger there are many dependencies and event chains. Especially in overriden save() methods and post_save and pre_save signals. Example: Like overriden A.save creates two related objects to A - B and C. When C is saved, post_save signal is invoked which do another thing etc... How to make these event chains clear? Is there a way to visualise (generate automatically) such chains/flows? I'm not looking for ERD nor Class diagram. I need to be sure when doing something, that it won't affect something on the other side of the project so simple visualisation would be the best. -
Django Apps aren't loaded yet - can't import model

Django Haystack SearchIndex limit size of queryset
I am using Django Haystack together with Whoosh as a search engine in my Django app. In my search_indexes.py file I define index_queryset as follows: def index_queryset(self, using=None): queryset = self.get_model().objects.all()[:10] return queryset This throws an error: AssertionError: Cannot reorder a query once a slice has been taken. Is there any other way to limit the number of results indexed by Haystack? I'm not really sure what is happening behind the scenes to cause this error. My model has a Meta field for ordering. What I want is the first 10 results that I'd get if I selected them all, with that ordering, and then just took the first 10. Help please? -
How do I write a Django query where the left side of my WHERE condition is a math expression?

Django Form saving

Django "list_filter" based on the admin queryset
I am developing an application which has both admins and sub-admins. Sub-admins are created based on the group they belong to. So a sub-admin can see only data which is related to his group. This functionality is working perfectly. Now, I want to create a filter option based on users. For super-admin it works fine but when I see from sub-admin, I can see the complete list of users in the filter list. How can I limit this list based on sub-admins users. Suppose there is a total of 20 users, and sub-admin has only 3 users in his group. So I am able to see only 3 in the list view but in the filter option I can see all 20. Can I limit this filter to only those 3 users only? My admin model looks like below: class VideoDetailsAdmin(admin.ModelAdmin): list_display = ('video_id', 'user', 'status', 'description', 'video_name', 'upload_time', 'duration') list_filter = ('user', ) def get_queryset(self, request): # Get the groups of logged in user query_set = Group.objects.filter(user = request.user) group_list = [] for g in query_set: group_list.append(g.name) # Get the user ids of Users in those groups id_list = [] for user in list(User.objects.filter(groups__name__in=group_list)): id_list.append(user.id) # Create unique users … -

Django: Ignore type of data of form field
I have a class which has an IntegerField attr. In its ModelForm, in the field of this attr, I need to send a String, which later will store an Integer once it is processed in the view. The problem is that Django doesn't allows this, and when I use form.cleaned_data.get('myattr') it's saying that it's wrong because it should be an Integer. class Student(models.Model): teacher = models.IntegerField(null=False) # I'm saving teacher's key here class Teacher(models.Model: name = models.CharField(max_length= 50, null=False) key = models.IntegerField(null=False) class StudentForm(forms.ModelForm): teacher = forms.ModelChoiceField(queryset=Teacher.objects.all(), label='Select the teacher') So, when the user is selecting the student's teacher, that select field will display the name of the teachers available. But in the model it will store their key, which I manage in view. views.py: teacher = form.cleaned_data.get('teacher') # it has the name teacher = Teacher.objects.get(name=teacher).key # getting the key in order to store an Integer, but Django is banning my code before anyway. How can I handle this without changing the data type of the model?
