Django form - How to save data or get data without having to save it to database?
I've created a form with some fields for users to enter data, and a button to submit them and run some functions, then display the results on the same page (without having to store it to the database). Now I would like to add a button (view/download as PDF) to have the page generated as a PDF file, so that the user can save the results. But I'm having trouble retrieving the entered data, even they are still displaying on the page. They don't seem to be stored in the variables (or I don't know where to look). I've read that if using modelForm I can call the .save function and save data to the database. But for this app I don't really need a database (it's more like an one-off calculations). So I would like to know if there's any way to: Get the entered data directly while they are still on display (after submitting the form). Generate a PDF directly from what's on the page (like the print to PDF file function that most browsers have, but with some customization such as without the headings and navigation bars). Is there a way to do this? I've been searching … -

Model hierarchy in Django
Sorry for the long text Models are given: User Hierarchy There are users, they can invite each other. The invitees, in turn, can accept the invite or reject it. Suppose that Mark invited Masha, Katya and Dima. Masha accepted Mark's invitation, and even invited Kolya herself. On one tab, you need to display the hierarchy. Continuing the example, Mark should have: 1st level: Masha, Katya, Dima 2nd level: Kolya and other guys 1st level for Mark - those whom he invited. 2nd level - those who were invited by people invited by Mark. And so on. Tell me how to implement it | what to familiarize yourself with to get closer to the result -
Django: saving models using parallel processing
I have a 35000 list of items which i have to update. I am planning to use bulk update. In bulk update we have the batch_size=option. I am planning to use a batch size of 20. Now what i found is that this runs the 20 sets of update in sequence. one after another Is it good idea to parallelize the update sets. If yes, how can i do it using multiprocess I came to know about multiporcessing a bit: import multiprocessing import django django.setup() # Must call setup def db_worker(item): from app.models import Model1 Model1.bulk_update(item).save() if __name__ == '__main__': list_update_values = 3500 items list_chunks = [] chunk_size = 20 for i in range(0,35000,chunk_size) list_chunks.append(list_update_values[i:i+chunk_size]) p = [multiprocessing.Process(target=db_worker,args=(item)) for item in list_chunks] p.start() p.wait() Will this going to help much -

How to store video transcripts in a database
I have some video transcripts that I would like to be able to search and filter on. They are stored in SRT files currently. I have around 200 files/videos and they are for videos that are 4 hours long and each file is around 200-400KB depending on the length. I'm using Django for my backend and a Postgres database. Here's a snippet of an example: 1 00:00:00.503 --> 00:00:02.782 SPEAKER 1: text text text 2 00:00:02.782 --> 00:00:04.090 SPEAKER 2: more text So I was thinking I might store it so each of the pre-made blocks as a single entry in my db. So I would have a table like: speaker | text | start | end I'd say per file there is 6k entries so that's around 1.2 million records and it will keep growing. I'm not sure if that's going to be fast for a text search. How should I store my transcripts so I can search by text and filter on speaker quickly? -
Passing List of Dictionaries to Django View Using Ajax
I am new to Ajax and Django, so I might be missing something basic here. I am trying to pass a list of dictionaries to a Django view. Example: data = [ {'item':'itemname','qty':'qty','price','price'},{'item':'itemname','qty':'qty','price','price}, etc. ] I have set up my Ajax call to fire when a button is pressed. My cart.js $(document).ready(function(){ var userCart = grabCart(); userCart = JSON.stringify(userCart); $("#Checkout").click(function(){ $.ajax({ URL: some URL headers: csrf_token, //Im passing the token using Django type: 'POST', data: {'userCart':userCart}), success:function(){//stuff} complete:function(){//stuff, but its routing to confirmation.html} error:function(){//stuff} }); }); My Django view def confirmation(request): data = json.loads(request.POST.get('userCart')) # <-- this line is throwing the error print(type((data)) # this prints out list print(data) #this prints out the list of the dictionaries return render(request,'confirmation.html') I keep getting an Error 500, Type Error. The JSON object must be str, bytes, or byte array, not NoneType This is confusing. The results are there but Django is throwing an error and won't render the confirmation page. -

django-activity-stream with aggregation
I'm using django-activity-stream to create a feed of goals. A simplified version of Goal object is as follows: class Goal(models.Model): user = models.ForeignKey(User, related_name="goals", on_delete=models.CASCADE) liked_by = models.ManyToManyField(User, related_name="goals_cheered") title = models.CharField(_("title"), max_length=80) There are 2 actions in place: the goal should appear in the feed once it's created and once it has been completed. Then users can like the goal, and here's where I'm stuck: adding the 'likes' count on the feed. This was the (failed) attempt that made the most sense to me so far: from django.db.models import Prefetch goal_qs = Goal.objects.annotate(likes=Count("liked_by")) prefetch = [Prefetch("action_object", queryset=goal_qs)] # in a `group` feed: qs = group.target_actions.all().prefetch_related("actor__profile").prefetch_related(*prefetch) This gives me a ValueError: "Custom queryset can't be used for this lookup." Maybe it's because django-activity-stream uses GFKs? How can I get a count of likes? Can I limit the content_type somehow? -
Django template not rendering time correctly
I have datetime object that I need to show in two different timezones.

How to dynamically select django model fields in views.py
I am using the DRF and I am trying to dynamically select fields from a django model object so that I can compare them to incoming data. I know how to do this manually def put(self, request): businessPage = BusinessPage.objects.get(id=request.data['id']) if businessPage.name != request.data['name']: businessPage.name = request.data['name'] if businessPage.address != request.data['address']: businessPage.address = request.data['address'] businessPage.save() res = { 'status': 'Success' } return Response(res) While this works it feels very messy and repetitive so I started looking for a way to dynamically check if the object field matched the incoming data. def put(self, request): businessPage = BusinessPage.objects.get(id=request.data['id']) for obj in request.data: if businessPage[obj] != request.data[obj]: businessPage[obj] = request.data[obj] businessPage.save() res = { 'status': 'Success' } return Response(res) I haven't been able to figure out the correct syntax to get the correct field from businessPage. Is this possible? Is there a better way to accomplish this task? Any help here would be much appriciated! -
Creating seperate URL endpoints for text files for a SaaS application
I have an architecture question so I don't need a specific answer but some guidance around a general approach. I am running a single Django App which has multiple GraphQL endpoints (multiple schemas on a single database). As an example I have the following endpoints all running from the same database: - example1.com/graphql - example2.com/graphql - example3.com/graphql I have a requirement to expose a text file which will be publicly accessible. e.g. - example1.com/textfile.txt - example2.com/textfile.txt - example3.com/textfile.txt Each text file will have its own data in it related to the customer URL. The problem I have is that at moment all of the URL endpoints write data to the same text file (since it is not stored on the schema). What I need is for them to write this data to distinct and seperate text files. What is the best way to resolve this problem - is it best to write this data straight to something like AWS S3 storage and create folders for each URL. In the case of S3 storage, is it possible to run append and delete operations on the text file directly. Any help is really appreciated. -

I am trying to use Django All-Auth forms in a predefined Bootstrap template so I want my fields to match the styling. Therefore I want to use each field individually in the template such as; I have done this successfully for the LoginForm by adding custom attributes to the fields in my forms.py. class YourLoginForm(LoginForm): def __init__(self, *args, **kwargs): super(YourLoginForm, self).__init__(*args, **kwargs) self.fields['login'].widget = forms.TextInput(attrs={'type': 'email', 'class': 'form-control', 'name': 'loginUsername', 'id': 'loginUsername', 'placeholder': 'name@address.com', 'autocomplete': 'off', 'required data-msg': 'Please enter your email'}) self.fields['password'].widget = forms.PasswordInput(attrs={'type': 'password', 'class': 'form-control', 'name': 'loginPassword', 'id': 'loginPassword', 'placeholder': 'Password', 'required data-msg': 'Please enter your password'}) And then referring to them with the following template tags. {{form.login}} {{form.password}} However, when I try and repeat this for the SignUpForm, I keep getting a key error which returns password1.

Use Django Channels without views
We want to use Django Channels to use Keras with Tensorflow as model. We've tried Flask but it's not usable for production. Then we tried Javas DeepLearning4J but also got to many problems. We want to solve it with Python. The problem is that Django is fullstack and we just need to use the websockets and execute our python code and send the results back. There is literally no example on Google how to do this. We do this because we got an Angular frontend, Spring Boot backend and another Spring Boot Application as connector between all services. We don't need the most functionalities of Django. It's very hard to find out what do. There is no @socket.route or something like this I think. Websocket using Django Channels this question was maybe a bit helpful but 3 years old and probably outdated. What is the way to achieve what we need?
