If I need more custom functionality can I manually write HTML forms?
I started coding a couple years ago but it's all been in Python and I never learned HTML/CSS real in-depth. I've now got a decent grasp of Django and somewhat of how the data gets passed around Django but I've noticed some limitations to the functionality I am trying to achieve using Djangos forms module. I think it would help better if I understood the front-end better. This has got my attention so I started to try learning about front-end frameworks like react.js, as well as HTML/CSS/vanillaJS. Today I'm a couple hundred pages deep into an HTML book and finding out more about forms than I knew. I've always seen the forms from the Django side (other than a few manual HTML forms I write every now and then). So I guess my question is, and it might be stupid, can I simply render a function based or CBV for that matter and pass the context I need and do fully custom forms in the front-end? Then grab that data back in the view using request.GET? How to handle form validation like this? Is this one way of expanding the functionality of Django if I'm reaching limitations? I know it … -

Communicate with other Django Servers using Docker
I'm new to Docker and want to build a Django webapp. The app shall run on multiple computers with a central server, which basically run all the same image. The main point is that there will be computing tasks which I want to distribute over the servers. So now I wonder how I would communicate via Django between the different Servers. I know about basic Distributed styles and Architecture protocols, but how do I expose the local network to the docker image network layer, so that I can communicate on custom ports and IPs in my network? I read about Docker Swarm, but how to forward the Addresses to each Django Server? What is a best/recommended/efficient way to distribute tasks between my Django Apps with Docker? -

Handling Django File from Model
I've created a basic model in Django and want to do some processing on a file in the background before sending to the template. At the moment I'm getting errors about a FileDescriptor object, which I cannot seem to find methods or attributes for, I was expecting something I can get a url or file contents from: class Projects(models.Model): image = models.ImageField(upload_to='uploads/') title = models.CharField(max_length = 200) desc = models.TextField() date_posted = models.DateTimeField() notebook = models.FileField(upload_to='notebooks/') I'd like to perform some processing on the file object in a generic view, but I don't really understand what is getting passed through. How can I just get the file url, or access to the actual contents of the file? Seem unable to get .url or .file attributes as I expect from FileField. class ProjectListView(ListView): model = Projects template_name = 'project_list.html' context_object_name = 'projects' def get_context_data(self, **kwargs): j = Projects.notebook.url context = super().get_context_data(**kwargs) ## insert functions to process object j ## context['notebook'] = j return context Thanks! -

How not to deploy under git control db.sqlite3 file
In my django project, db.sqlite3 is under git control(I chose to do so). However when deploying the project to AWS server(using elastic beanstalk), I would like not to deploy db.sqlite3 file.

Having trouble restricting editing to the owner of the profile in Django while using a custom user model
I am new to development and Django. This is my first project from scratch. I am also new on here, so if I don't ask a question correctly, please give me some feedback rather than downvoting. So, I decided to go with a custom user model so I could customize the registration page and require users to submit a photo during registration. I am not sure if I needed to go through all this just for that, and I am finding out that it's more difficult to manage a custom user class. Right now, I am attempting to only allow the current logged in user to be able to edit their own info, not anyone else's. I totally know how to do this through the normal User model, but I can't figure out how to do this through the custom user model path. The only way I know how to do this is to create a separate model that has a foreign key to my Profile model, 'owner', and compare the two ID's when the current user try's to edit someone else's profile. I looked around a couple different related questions, and I couldn't come up with a solution either. … -

Sending a Python Dictionary Through a Single POST method in Django REST Framework
I have been attempting to implement this method several ways in which seems like it should be pretty straightforward. I have a web scraper that scrapes stock data and stores it into a Python dictionary in a python script. This then makes a post request to my Django API which is handled under my views using GenericAPIView. This post request sends a QueryDict and I am able to post a single instance but not multiple at once. Yes, I have said many=True on my serializer and attempted to override these methods. Each solution I have made is inefficient and I am frustrated not finding a clear and simple solution. This is my first time working with the Django Rest Framework so bear with me and thanks for your help in advance! CryptoView.py (Mostly followed a tutorial on Medium.com to improve my method) class CryptoView(ListCreateAPIView): queryset = Crypto.objects.all() serializer_class = CryptoSerializer def get(self, request, *args, **kwargs): return self.list(request, *args, **kwargs) def post(self, request, *args, **kwargs): return self.create(request, *args, **kwargs) class SingleCryptoView(RetrieveUpdateDestroyAPIView): queryset = Crypto.objects.all() serializer_class = CryptoSerializer Cryptotest.py crypto = { "id": [], "name": [], "price": [], "change": [], "percentChange": [] } # For Loop - Yahoo Finance requires us to … -
Why does OneToOne relationship cause long load - very slow Django?
I've added a OneToOneField to my models.py. Once I do this my detail view takes almost a minute to load when before it took less than a second. See below list for reference method flowchart of what Django docs says happens in a DetailView. Whatever is happening its happening after render_to_response (last one) and get_success_url (not listed). I added a print('HELLO') to both. I see render_to_response's HELLO immediately. Chrome spins/loads for a minute or two. And then I see get_success_url's HELLO. What happens between render_to_response and get_success_url?

Deserializing model with multiple parent models throws "...object has no attribute..." error
First of all sorry for the long post. I'm just trying to really break down the issue. I'm using the django-moderation and django-comments-xtd packages to implement moderation for comments. I use the following model on top: class VotableComment(XtdComment): vote_score = models.IntegerField(db_index=True, default=0) (...) The XtdComment itself inherits from the Comment model from the django-comments package. Behind the hood all this works through OneToOneFields i.e.: migrations.CreateModel( name='XtdComment', fields=[ ('comment_ptr', models.OneToOneField(auto_created=True, primary_key=True, parent_link=True, serialize=False, to='django_comments.Comment', on_delete=models.CASCADE)), (...) migrations.CreateModel( name='VotableComment', fields=[ ('xtdcomment_ptr', models.OneToOneField(auto_created=True, on_delete=django.db.models.deletion.CASCADE, parent_link=True, primary_key=True, serialize=False, to='django_comments_xtd.XtdComment')), (...) This means that a VotableComment object should have both comment_ptr and xtdcomment_ptr as attributes. The error comes when django-moderation tries to set the changed_object attribute (which refers to the VotableComment object) of its ModeratedObject model which is a SerializedObjectField field. Then I get: The underlying issue happens when deserializing and trying to set the values of the VotableComment object's fields obtaining the value from its parent models. In particular the comment_ptr field: As you can see there is a problem when trying to set comment_ptr with value <Comment: :...> on the VotableComment model because later on related_descriptors.py is first trying to resolve all the inherited_pk_fields. There are two of them which come from the … -
