New ManyToManyField object is not adding
I am building a BlogApp AND i made a feature of Favorite Users in the ManyToManyField. It means user_1 can add multiple favorite users in one field. I build a view to add users. BUT when i create an instance to store favorite users from Admin before adding favorite users from site AND then if i add favorite users from site then they are adding. BUT if there is not already a instance of request.user's FavouriteUsers in Admin then it is not adding and creating a new object. So, A new object for storing favorite users of request.user is not adding, AND if object is already there then they are adding. models.py class FavoriteUsers(models.Model): user = models.ForeignKey(User,on_delete=models.CASCADE) favorite_users = models.ManyToManyField(User, related_name='favorite_users', blank=True) views.py def AddFavUsers(request,user_id): obj = FavoriteUsers.objects.filter(user=request.user) user = get_object_or_404(User,id=user_id) for ob in obj: ob.favorite_users.add(user) ob.user.add(request.user) ob.save() return redirect('home') Image of already created object When object is already , manually created then favorite users are adding BUT if it is not then new object is not creating. Any help would be much Appreciated. Thank You in Advance. -

How to make web-scraping faster? Django project
I'm building a web-scraping application using the Django framework. I need some tips on how to speed up my application. As of right now, it takes almost a minute to load the page just parsing through 3 urls which is a problem. I'm going to need to run a lot faster as I want to parse through up to 10 urls on my webpage. As you can see, I'm only targeting one div with my code which is why my application is running so slowly. I'm thinking I could try targeting multiple divs to narrow down my "soup" but I've had difficulty with that in the past so I'm hoping to get some pointers. def stats(request): if 'user_id' not in request.session: return redirect('/') this_user = User.objects.filter(id = request.session['user_id']) this_stock = Stock.objects.filter(user_id = request.session['user_id']) progress_dict = [] for object in this_stock: URL = object.nasdaq_url page = requests.get(URL) soup = BeautifulSoup(page.content, 'html.parser') progress = soup.find_all('div', class_='ln0Gqe') for number in progress: progress_dict.append(number.text) context = { "current_user" : this_user[0].first_name, "progress_dict": progress_dict, "this_stock": this_stock, } return render(request, "nasdaq.html", context) -

Django Admin keep logout repeatedly. May because the DB is corrupted. How to fix this situation?
Let me describe how this problem Admin logout problem occurred. It was about few months ago. My DB is MSSQL. I was using Django 1.11, and I wish to update to Django 3.x . First I was updating my Django to 3.1, because of that, I have to switch django-pyodbc-azure to django-mssql-backend. And I did migrate after I update my Django to 3.1. But I didn't know that mssql-backend does not supporting Django 3.1. So I switch my Django from 3.1 to 3.0.x And I remember that I have to migrate again. But the migrations are the same. I didn't add any new migrations. Still, the migrate it applies something again: admin. {nums}_logentry_add_action_flag_choices auth. {nums}_alter_user_last_name_max_length auth. {nums}_alter_group_name_max_length auth.{nums}_update_proxy_permissions At this moment. I haven't login through Admin page. And I think I did change the Django versions after this (maybe two times again). Just because I was trying to find out which version is suit for me. So I don't really remember how many times I migrate before I found out the Admin logout problem. Anyway, I think I messed up something during the migrates. And it doesn't matter which Version of Django I use, 3.0.x ~ 3.1.x all have the … -

Django lost migration file
I have a django app connected to postgresql database (RDS instance running on AWS) Recently, I added new fields to my database tables, but forgot to run makemigrations locally and pushed the code to the server. The server went down since changes were not applied, and in order to fix the problem quickly I decided to run makemigrations and migrate directly in docker container of the application, I thought it would generate migration files, but unfortunately, it didn't. The migration was applied on database level, but there is no migration file of the changes. When running python manage.py showmigrations in the container, it outputs: redirect [X] 0001_initial [X] 0002_redirect_clicks [X] 0003_redirect_name But in database, running SELECT * FROM django_migrations; tells that there is one more migration: 103 | redirect | 0004_auto_20210707_2039 | 2021-07-07 14:39:19.058233+00 What would you advise? I thought of running makemigrations locally, generate the file and push it to vcs, and on the server apply the changes using migrate --fake. I don't know what this does exactly and I am too scared to do it without guidance, any help would be appreciated -

How do I update data of django model by simply clicking on a button without any form?
I'm working on a Django project. My motive is to update the value of status in the database by simply clicking on a button. I don't want to submit any form. This is what I've tried: Models.py class auction_listing(models.Model): title = models.CharField(max_length=100) status = models.BooleanField(default=True) def __str__(self): return f"{self.id} : {self.title} " Here status is the boolean field.

best Error handling with csv reader in django

Views.py # upload_id = (request.GET.get("id")) if request.method == 'POST': form = UploadForm(request.POST, request.FILES) if form.is_valid(): form.save() data = request.FILES['docfile']#.read().decode('UTF-8') words=get_keywords(data) results=list(find_skills(words)) for word in results: form2 = Resume_words(word = word, word_type='exclude', upload = upload_id) form2.save() return render(request, 'word_list.html',{ "results":results }) else: form = UploadForm() return render(request, 'upload.html', { 'form':form }) I having trouble pulling these pieces together and I'm desperate for help of any kind! I having trouble with the following steps: I don't know how to capture the current users instance when saving to the table. I get an … -
How do I query data from the database base on user in a completely separated frontend Django REST
So I have this basic model: class Text(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) title = models.CharField(max_length=255) def __str__(self): return self.title so usually when you're using regular Django and you want to query Text from the database based on the user you would do: def main_page(request): userTexts = Text.objects.filter(user=request.user) context = {} return render(request, '', context) but now I've been using Django REST React stack and built a completely separated frontend and the only way I access the data from the backend is by making HTTP request to it, so now request.user wont work anymore because it's just going to return anonymousUser fortunately though I already have an authentication system working and already have a user object inside my react state all I have to do is design a view and an API call to query the data from the backend but I cant imagine how to do both of those things. -
Django Queryset filter array field by exact string
so I haven't been working with Django for too long. I am running into a problem filtering a queryset by the exact name of a string of arrays that is passed into it. Currently, I am filtering the queryset by icontains, which works. For example the current implementation works like this: If I pass in one string called "test" my queryset will be filtered and show deals with tags "test1" "test2" and "test3". This is not what I want. I want to filter by the exact name of the strings that are passed in. So if I have a "test" as one of the strings then my queryset will only search for test, not anything that is contained into it. I've tried multiple implementations, such as switching from icontains to iexact, and exact. Goal. Filter queryset by array of multiple tags. old query: values is an array of tags (strings) that are passed in values = value.replace(" ", "").split(",") return qs.filter(reduce(operator.or_, (Q(tags__iontains=item) for item in values))) What I have tried: I have tried passing in the iexact with the list of values like below. I have also tried just passing iexact, and then passing in only one hardcoded string from …
