When saving an object from the django admin panel, I get error 400
When I create an object in django admin when I click save, nothing happens, I get an error.

'manager_method() argument after ** must be a mapping, not str' when overloading nested ModelSerialiver.create(...)
I want to overload a ModelSerializer create() method in a generic way using Django RestFramework inspection functions. for the purpose of testing the concept on a related_name of a ForeingKey i have the following models and corresponding serializer. models.py class Country(models.Model): pass class People(models.Model): country = models.ForeignKey( to="myapp.Country", null=True, blank=True, on_delete=models.SET_NULL, related_name="country_people" ) serializer.py class CountrySerializer(serializers.ModelSerializer): country_people = PeopleSerializer(many=True) def create(self, validated_data): country_people_data = validated_data.pop("country_people", []) instance = super().create(validated_data) for cp_data in country_people_data: cp_data["country"] = instance self.get_fields()["country_people"].create(cp_data) class Meta: fields= "__all__" model = Country example of data # json data for country serializer { ..., "country_people":[ {...}, {...} ] } When calling CountrySerializer.save() the CountrySerializer.create() will be called and it will save also nested data on People table. The issue is that I got the following error ModelClass._default_manager.create(**validated_data) TypeError: django.db.models.manager.BaseManager._get_queryset_methods.<locals>.create_method.<locals>.manager_method() argument after ** must be a mapping, not str using People.create(**cp_data) is working but it is not the solution in my context I want to solve it using self.get_fields because I want it to be generic and because PeopleSerializer could nest another serializer so back and so forth -

Why my exports are limited to 100 records only in django-import-export?
I am using Django import export in my project. I have ~5000 records in the model. In local, The export is working fine. [exporting all the records in csv] But in production, when I export to csv, Only 100 records are exported. The django app is hosted on Cpanel. I am using mysql phpmyadmin in production.

Best way to implement highly customized Django admin action
I'm trying to implement a custom Admin action that creates an OwnerInvoice object based on data from Receivable and Reservation objects. All Receivable and Reservation objects are related to only one Property object. Ideal workflow: Business admin selects property X to bill and shows a list of Reservation objects which are related to property X and haven't been billed yet. Admin can select which Reservation objects should be billed and a breakdown of the Reservation data selected is shown. On the same page, the admin should be able to choose from a list of Receivable objects (all related to property X and not yet billed). After selecting Receivables, a final page shows the breakdown of Reservation and Receivable objects and provides a total. By pressing save, an OwnerInvoice object is created and a PDF (OwnerInvoice method) is generated. The question: How would the StackOverflow community recommend I implement this kind of functionality into the Django admin? Possible ideas I've had but not sure if they would work with the above flow: Extend the OwnerInvoice's application app_index admin template to show a custom table containing Property object information. Use redirects for intermediate pages (using Reservation change_list and Receivable change_list). Extend the … -

can i launch a jango app from within pycharm without using terminal?
with other projects i've developed i have been able to hit 'run' to launch my application, and then shift+f10 from then on. it seems excessively cumbersome to have to launch the terminal and type python manage.py runserver every time i want to test something... is there a better way? can i write a python file like "run.py" with some script that will launch the app, or some other solution? i've searched for ages, and all i can find is a thousand tutorials telling me how to start a project, rather than how to launch it more easily. thanks -
Auto execute background tasks in django
I am trying to automatically run background tasks as soon as the server starts in django. Specifically, after the server boots and is running on localhost, I want it to run functions that fetch api data to fill my DB. What is the best way to do this? Is it celery?

Instagram followersssssss
I didn’t post a fancy and word-playing title. We are all social media brothers and let’s not fool anyone: I follow who follows! Being followed is a very uncomfortable and dangerous situation. In real life. In digital life, the equation is ‘slightly’ different. Which is disturbing and dangerous; not to be followed. Unfamiliarity of followers is not an inconvenience, but a reason for happiness. We don’t get depressed anymore, we look at a friend whose name is ‘disapproval’ and go out. This is the reality of the world – the digital one – whether we like it or not. I also offer a huge service to dear readers for the needs of the day, and this week I am giving tips on how to increase your followers on Instagram. Use labels. If possible, choose those that encourage mutual following, such as #instafollow, #l4l, followback. Follow those who use these tags. Do not neglect the ‘TagForLikes’ application, which allows you to instantly use the most popular tags practically. Like random photos of different people (Don’t always heart beautiful/handsome people, mix trees/plains together. Your girlfriend sees them). In one experiment, it turned out that for every 100 random photos liked, six followers … -
How to append a list in jinja3
