Using social-auth-app-django for Azure Active Directory authentication and DRF
It could be my approach is just entirely wrong and if so, being corrected would be greatly appreciated. Basically, I need to authenticate company users of the /admin portal in development against the company's Azure Active Directory. They are the only ones who should be able to access it. There are two approaches, as it was explained to me: OAuth for Servers: usually used when the app needs to access user data when they are not logged in. OAuth for Browser Apps: usually used when the app needs to access user data while they are logged in. Based on this, I went with 1, and decided to give python-social-auth, social-auth-app-django and the Microsoft Azure Active Directory a try. The examples are pretty old and it seems like I'm just missing something in the documentation to get it working. I'm using DRF, and aside from /api/admin (the Django Admin Portal), no static assets are being served by Django at all. The ReactJS FE is an entirely separate service. So an oversimplification of what should happen is: User navigates to https://example.com/ ReactJS automatically sends request to https://example.com/api/users/auth/aad/login User is presented with Microsoft login screen This is all I have so far: # … -
Getting comments for a post by certain users in Django using Postgre
I have two models Post and Comment. My users are able to build friendships with one another. I want to write a method that from a certain queryset of posts if the user's friends have commented on that post it will by consuming as less memory as possible. My models are: class Post(models.Model): title = models.CharField(max_length=100) content = models.TextField(validators=[MaxLengthValidator(1200)]) author = models.ForeignKey(Profile, on_delete=models.CASCADE) date_posted = models.DateTimeField(auto_now_add=True) class Comment(models.Model): post = models.ForeignKey(Post,on_delete=models.CASCADE,related_name='comments') author = models.ForeignKey(Profile, on_delete=models.CASCADE) body = models.TextField(validators=[MaxLengthValidator(350)]) created_on = models.DateTimeField(auto_now_add=True) now assuming I have a list of user id's which are friends with request.user By: friends = Friend.objects.friends(request.user) and I have a queryset of posts: posts = Post.objects.select_related("author").filter(author__in=friends).order_by('-date_posted') I can get the comment id of each post by: post.comments.values('id').select_related('author').filter(author__in=friends).order_by('-created-on')[:2] However, if I want to do this for hundreds of post it will be extremely expensive. How can I get the last two comments by a users friends from each post as fast as possible by using the least memory? -
Serializer for fetchiing data from multiple classes
Environment is Python and Django3 I want to make api which retrieve the data from multiple model class.

So I made the serializer for Country class CountrySerializer(serializers.ModelSerializer): latest_stat = serializers.SerializerMethodField() class Meta: model = Country fields = ('id','code','latest_stat') def get_latest_stat(self,obj): # how can I get the latest stat from CountryStat model ???? Is this the correct idea or how can I make it?? -
How to adding PDF for Admin to view Orders

websolr/heroku/django: How to set up solr as a separate service
I am trying to deploy my Django app on Heroku that uses calls to solr to field user queries. I added websolr as an addon to Heroku, but the websolr docs only describe how to configure clients like Django-Haystack. Since my app has users searching a static index and not Django models that need to be updated, and I already have schema.xml, solrconfig.xml, etc. and a json file to index that I know works, I don't want to try to recreate this using Django models for no reason. How do I get websolr to run solr based on these files that I provide instead of embedded to my app through a client? -
Can't log into a commandline created superuser using Django but account gets created
I have created a superuser that i can't log into, using the docker-compose.yml commands: sh -c "sleep 5 && #<snip> echo A-fj... create superuser acct... && echo DJANGO_SUPERUSER_PASSWORD=$DJANGO_SUPERUSER_PASSWORD && echo DJANGO_SUPERUSER_EMAIL=$DJANGO_SUPERUSER_EMAIL && echo DJANGO_SUPERUSER_USERNAME=$DJANGO_SUPERUSER_USERNAME && python manage.py createsuperuser --noinput --username $DJANGO_SUPERUSER_USERNAME --email $DJANGO_SUPERUSER_EMAIL && echo Z-fj... create superuser acct... done. && #<snip> sleep 5 " The environment variables display perfectly, and an account gets created that i can see in the db using dBeaver. When i manually add a second user via "$python manage.py createsuperuser" dialog, i end up with an account that i can log into. When i copy the password from User2 to User1, i can then log into User1 using User2 password, so it seems to be a password thing. When i compare the passwords from User1(orig) and User2(new), they look to be different formats... see the screenshot. I'm not sure, but thinking it may be a clue to the problem... Password1 is shorter and has no sections where Password2 is longer...

Trying to load a ML model in Django in order to classify user submitted images
I have made a small image classifier that I want to use in my website. I have it working locally. My view is something a long the lines of from .predict import classify def index(request): if request.method == 'POST': form = MyImageClass(request.POST, request.FILES) if form.is_valid(): cd = form.cleaned_data context = classify(cd) return render(request, 'my_html.html', context) ... Where the problem is in predict.py, I have def classify(cd): loaded_model = tf.keras.model.load_model(filepath=r'C:\Django Projects\my_project\my_app\trained_model') ... return context As I said, the above works, but I would like to be able to load the model with a relative file path instead. I have tried both saving as a SavedModel and as an h5 file as done here. When I run tf.keras.model.load_model('my_model.h5') (say in main.py) in python, I have no problem with the file being in the same directory as the file main.py, but if I have the same code as part of predict.classify, I get OSError: SavedModel file does not exist at my_model.h5/{saved_model.pbtxt|saved_model.pb} while using my website via py manage.py runserver. I'm guessing the issue might have to do with static files? I'm not too sure. Any help would be greatly appreciated. -
Only show in Django Admin the facilities that belong to the customer for which the work order is being created
In myApp I have a Client who owns different ClientFacility. I also have a Project which is done for a Client. In addition I have Orders that belong to a Project (and indirectly to a Client). The Orders for a Project will be performed only on ClientFacility owned by the customer associated to the Project. I was trying to understand the filtering of many to many on this question but I couldn't because I don't know how to get my project_number dynamically In myApp admin section (http://127.0.0.1:8000/admin/myApp/), every time I create an Order, I would like to show only the ClientFacilities associated with the Client of the Project the Order belongs to. How can I do this and on which .py of myApp? Right now the ManyToManyField displays every single ClientFacility on my database which is not adequate. If the way in which I have established the relationships between my models is not correct it is fine, I want to learn. Please provide some guidelines, links, examples, etc instead of saying this is all wrong and it has to be changed. This is my code: class Project(models.Model): project_number = models.IntegerField(unique=True,primary_key=True) project_name = models.CharField(max_length=400) client = models.ForeignKey("Client", on_delete=models.CASCADE,verbose_name = "Customer of … -
Django (Models): Automatically pick and return a value by the choice option
I'm building a simple sys which selects a link by given value. So imagine a user is posting a post and he has to select the type of the post for example (old, new, classic).

I want to do something like this: If the CharField default or given value is - "2", I set the current model Charfield value to 'https://i.imgur.com/kM9Ppou.png' But this does not work as it should, In the previous attempts I was using IntegerField, but I realized that IntegerField couldn't store link because it's a string.

How to paginate Django Admin for Order Model

Django | CSRF Verification Failed
I'm building a Django powered blog-like app for practice and learning. I'm working on setting up a form for users to leave comments on posts. I have a Post model that takes in a User foreign key, and a Comment model that takes in a User foreign key and a Post foreign key (to identify the post the comment is tied to).

Docker and Django – keep everything up to date & secure
I am new to Docker and begin to understand how that whole thing works. My final goal is to deploy my Django project (which at the moment is running locally) to Google Code Run or a similar service, but there is still a way to go. Actually, thanks to this book, I already got my project running within a Docker container locally on my Mac, which is great. My Dockerfile starts with FROM python:3.8 and contains COPY Pipfile Pipfile.lock /code/ RUN pip install pipenv && pipenv install --system So every time I build my container, updates wich are available for Linux, Python, Django and other packages I am using are included automatically, I guess (unless I declare otherwise e.g. for packages in my Pipfile). The idea is to develop the app locally and test everything using Docker on my Mac. When it comes to updates, I have to check if everything is still consistent. If everything works fine locally, I (later) can deploy the container to somewhere else and everything should be fine. Am I basically right or did I miss something important? -
URL parameters don't select designated options in select2 drop-down
I have created URL parameters on my site. For example, I have multiple custom widgets including a calendar, toggle switches, and more. My question is when I access a certain URL with my parameters I get the right plot/graph, but the options selected in my drop-down won't get selected? The parameters get applied to all my other widgets, but my select2 drop-down. It definitely takes in the right options selected, but won't display to let the user know the parameters passed were successful. I hope I am making sense, but to sum it all up when I pass my desired parameters my site will load as expected. However, the options will not get selected and display to the user. The URL parameters were created using a GET request. Here's my js file $(document).ready(() => { $.fn.select2.amd.require([ 'select2/utils', 'select2/dropdown', 'select2/dropdown/attachBody' ], function (Utils, Dropdown, AttachBody) { function SelectAll() { } SelectAll.prototype.render = function (decorated) { var $rendered = decorated.call(this); var self = this; //define the buttons inside the menu var $selectAll = $('<input type="checkbox"> Select/Unselect All</input>' ); //append the buttons inside the menu $rendered.find('.select2-dropdown').prepend($selectAll); // Pass in an array to our value to select all. // Check if checkbox has been … -
The 'Access-Control-Allow-Origin' is not included on response header for images
I'm developing a simple web app, using Nuxt for the frontend and Django for the backend. The Django API has 2 endpoints, tag and product, and in the product endpoint there's a image_url value, which contains the link to a JPEG file, stored in a Django server sub-directory called media. Since both apps are being served on different ports (frontend in 3000; backend in 8000), I needed install the CORS headers package for django, and I configured it like this (on settings.py): CORS_ORIGIN_ALLOW_ALL = False CORS_ALLOW_CREDENTIALS = True CSRF_TRUSTED_ORIGINS = ( '<my-host>:3000', '<my-host>', ) CORS_ALLOW_METHODS = ( 'DELETE', 'GET', 'OPTIONS', 'PATCH', 'POST', 'PUT', ) CORS_ALLOW_HEADERS = ( 'accept', 'accept-encoding', 'authorization', 'content-type', 'dnt', 'origin', 'user-agent', 'x-csrftoken', 'x-requested-with', ) CORS_ORIGIN_WHITELIST = [ 'http://<my-host>:3000', ] Then, on the frontend, I use axios for the HTTP request. The strange thing (at least for me) is that the CORS headers are included in every request made to the API, but not on the images. So, with an HTTP request for http://<my-host>:8000/product/1, the response includes (among other things) this: { "id": 1, "image_url": "http://<my-host>/media/images/1/20200916113917386794.jpg" ... } By examining the Network tab, on Chrome's DevTools, I see the following response headers from http://<my-host>:8000/product/1: Access-Control-Allow-Credentials: true Access-Control-Allow-Origin: http://192.168.33.11:3000 …
