How to test api with session in django
I am currently building an auth app that provides register, login, logout ... functionalities. Everything seems to work fine, however when I log the user in, I cannot logout, I get an Anonymous user error instead. After searching on the internet I came to the conclusion that it is not the best to build an api with sessions and instead to use tokens(JWT). With sessions I cannot test my API with tools like POSTMAN because that requires cookies (technically you can use cookies in POSTMAN though). Having said that, sessions seem to be more stable and secure so how would I go about testing my API using the sessions stored in the cookie? Thanks. -
Developing a web application with python
I would like to learn to write a web application using python. The application will write information into and retrieve data from a PostgreSQL database I will be hosting on a personal web URL. I would like to securely log into the application and select (or create a new) item/file to work on. The file will have a structure like an indented bill of material a user can dig down into if the data exists or can build if it does not. I am expecting to build the structure with Python classes, but I don't know where to start with building the GUI for the web browser. I would like to have a slick interface with a tree structure on the left of the screen I can expand and dig down or add items, and a form containing information on the right (or blank properties if the item is being added). Eventually I would like to show analysis and various other views of the data contained in the database including graphs and summary tabs. Would Django be the right tool to use to build the web app or Flask or is there something better I should spend my time learning. … -

CurrentUserDefault doesn't work with AnonymousUser
I'm trying to use CurrentUserDefault with a field that can be null: # model class Package(models.Model): # User can be empty because we allow anonymous donations owner = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True, blank=True, ) # serializer class PackageSerializer(serializers.ModelSerializer): owner = serializers.HiddenField(default=serializers.CurrentUserDefault()) Everything works fine when a user is logged in.

Python - Django MySql raw sum returns single value
Beginning in Django, I try to query data from MySQL and running with an issue while I try to use raw. I return, I correct values, grouped, but not summed (only return last value for that group I guess). My query works good when I run it on MySQL directly, just not with objects.raw. Any idea why that is / How to work with that? My code is as below. yesterday = date.today() - timedelta(days=1) list_parts = PqList.objects.raw('SELECT id, SUM(quantity), equipment_id, so_number FROM pq_list WHERE date > %s group by equipment_id, so_number', [yesterday]) context['list_parts'] = list_parts -
Django message framework doesn't show messages
I have a flow where one page adds a message to Django's message store (CookieStore) and another page displays that message (by rendering it onto a template). All works nicely in most environments. However I have one environment where the message doesn't show. I can see the cookie being set, but it is not getting removed in the "other" page load. My question is - are there any env variables that may be preventing the messages from being cleared from store and rendered onto a page, or any other settings to look out for? This environment is not easy to debug, so I can't set any breakpoints and searching the code didn't reveal anything obvious. -
How to create view and serializer to add to many to many field in DRF
I implemented two models, Card and Dish. I used many-to-many relationship because Dish can be in many cards. Furthermore, I have been struggling and could not get answer anywhere how to update created card with dish. Or create a card with dishes in it.

Optimal way to fetch related model and through model together in ManyToManyField
Given schema: class Investor(models.Model): name = models.CharField(max_length=30) advisors = models.ManyToManyField("Advisor", related_name="investors", through="Connection") class Advisor(models.Model): name = models.CharField(max_length=30) class Connection(models.Model): investor = models.ForeignKey("Investor", related_name="connections", on_delete=models.CASCADE) advisor = models.ForeignKey("Advisor", related_name="connections", on_delete=models.CASCADE) blocked = models.BooleanField(default=False) And given an Advisor "a", what is the optimal to fetch a list of all Investors and their Connection to "a" when it exists? The best I've figured out so far is: from django.db.models import Prefetch for investor in Investor.objects.prefetch_related( Prefetch( 'connections', queryset=Connection.objects.filter(advisor=a), to_attr='connection', ) ): name = investor.name blocked = None if investor.connection: blocked = investor.connection[0].blocked print(f"{name} (blocked={blocked})") -

Django ImageFiled thumbnail from video
I need to make a thumbnail from a video and save it to Django's ImageField. I already have the working code which saves the thumbnail to a specified folder but what I want is to redirect the output of FFmpeg directly to Imagefield (or to a in memory uploaded file and then to Imagefield) This is my current code: def clean(self): file = self.files['file'] output_thumb = os.path.join(settings.MEDIA_ROOT, 'post/videos/thumbs', file.name) video_input_path = file.temporary_file_path() subprocess.call( ['ffmpeg', '-i', video_input_path, '-ss', '00:00:01', '-vf', 'scale=200:220', '-vframes', '1', output_thumb]) self.instance.video = self.files['file'] self.instance.video_thumb = output_thumb I'd like to do it so that I wouldn't need to specify the folder to save the thumb in (output_thumb in the code) and for Django to save it automatically using the upload_to='post/videos/thumbs option in the model definition Please point me in the right direction of how to do this. -
Django filter queryset for each item
I cant think of a good logic myself so I hope that somebody could help me out. The goal is this: I have a date which a user can enter, a from_date, prognosis_hour, to_date and default_hour. I need to filter from the employee_set each employer who has a from_date with his prognosis_hour within the range of the date which a user enters, to sum it with other employee hours, the twist is, when there are employees without from_date with prognosis_hours, then default_hour should be used. Now I have this @property def prognosis(self): mylist = [] for e in self.employee_set.exclude(prognosis_hours__isnull=True, from_date__isnull=True): for i in self.employee_set.filter(from_date__gte=self.entered_date, to_date__lte=self.entered_date): e.default_hours mylist.append(i.prognosis_hours) mylist.append(e.default_hours) return mylist right now it filter everybody within the entered date and append it to the list, showing default and prognosis hours, but ignores everybody else with default hours In the end it should just sum all default and prognosis hours together when prognosis hours are within range of the date today or the entered date from user I know that the sum is missing and that I can append it together etc. it is copied from my debugging process class work(models.Model): entered_date = DateField() @property def prognosis(self): mylist = [] for … -
