Django - Retrieve or get data from selected foreign key field
Relatively new to Django, I'm working on a Django project and attempting to retrieve particular foreign key object into variable when it's selected in Form. model.py class item_category(models.Model): idItemCat = models.CharField(primary_key=True max_length=5) nameCategory = models.CharField(max_length=150) def __str__(self): return self.nameCategory class item_code(models.Model): idItemCat = models.ForeignKey(item_category, on_delete=models.DO_NOTHING) idItemCode = models.CharField(primary_key=True, editable=False, max_length=20) def __str__(self): return self.idItemCode I know I could retrieve object with making QuerySet such as .objects.last() and .objects.filter() or else, but it's just retrieve objects from database or existing data. What I'm about to do is, when a user submit a new data it'll retrieve particular foreign key object based on what I'm selected in this Form, so I could put into variable. Any idea how should do it? it would be so much appreciated. -

Django: DB queries count optimization
I have models (one user can has multiple employees): from django.db import models class User(models.Model): username = ... first_name = ... last_name = ... class OrgUnit(models.Model): name = .... address = ... class Employee(models.Model): personnel_no = ... user = models.ForeignKey(User, related_name='employees'...) orgunit = models.ForeignKey(OrgUnit, ...) Serializers and views: class EmployeeSerializer(serializers.ModelSerializer): orgunit = serializers.CharField(source='orgunit.name') <==== one orgunit - one query to DB class Meta: model = Employee fields = '__all__' class CustomUserSerializer(serializers.ModelSerializer): employees = EmployeeSerializer(many=True) class Meta: model = User fields = '__all__' class UsersViewSet(ViewSet): def me(self, request): serializer = CustomUserSerializer(request.user) return Response(serializer.data) When serializing orgunit.name per one orgunit one query to DB is being performed. How to avoid this? How to prefetch employees related_name and its orgunits? -

Best practice to show complex Json on the browser in javascript
I want to show the json object as tree like UI in browser. At first I try this [jqTree][1] However it requires that json will be this style { name: 'node1', children: [ { name: 'child1' }, { name: 'child2' } ] }, Without name childeren node , no tree appars. However my style is more complex and different node name. { title: 'node1', choices: [ { title: 'child1' , choices:[] }, { title: 'child2' choices:{ "answers":[1,2,4] } } ] }, Is there any good method to show more flexible json?? -

Bulk Create instances using same info but different photos in django admin?
I'm working with this Media model: class Media(AbstractCreatedUpdatedDateMixin): uuid = models.UUIDField(unique=True, default=uuid4, editable=False, db_index=True) user = models.ForeignKey(User, related_name="uploaded_media", on_delete=models.CASCADE) title = models.CharField(max_length=255) location = models.PointField() image = models.ImageField(upload_to=uuid_directory_path) category = models.CharField(max_length=9, choices=ContentType.choices()) In some cases multiple photos represent the same thing, so the values of user, title, location and category will be the same, and I need this functionality in the admin page.

How to make the instance inside Django form take multiple values?
I'm making a Django blog and I want to make the user edit his post.

Django admin: pivot table for through model?
I have 2 models: ecrf and calendar. These models are parameters models for app and set via django admin interfaces. class Ecrf(models.Model): ide = models.AutoField(primary_key=True) name = models.CharField("Nom du modèle",max_length=50, null=True, blank=True) class Calendar(models.Model): ide = models.AutoField(primary_key=True) timing = models.CharField("Timing",max_length=50, null=True, blank=True) class EcrfCalendar(models.Model): ecrf = models.ForeignKey(Ecrf, on_delete = models.CASCADE, related_name = "ecrf") calendar = models.ForeignKey(Calendar, on_delete = models.CASCADE, related_name = "calendar") expected = models.BooleanField() vis_typ = models.IntegerField('Visit type (live or phone)', null=True, blank=True) The ecrf model contains type of form that can be collected (eligibility, inclusion, visit). The calendar model contains timing when a form can be completed (Day -1, Day 0, Day 3, Week 1). Some forms are only completed at one timing: e.g. eligibility at Day -1 and inclusion at Day 0. Other forms can be completed at multiple timing: e.g. visit can be collected at Day 0, Day 3 and Week 1. ecrf and calendar models are linked with a manytomany relationship. I explicitly define the through model ecfcalendar. I could use inline forms for admin form but I would like to have a django admin form that enable user to "check" timing of form collection using a pivot table presentation (cf below). Is it possible? -
django find in field type json with value type int or str
I have a field type Json in a model, but I can't be sure if it's an integer or a string, the long version that works is: cars = Car.objects.filter( user_id=self.user_id, car_type=self.car_type, facture__facture_id=1, ) if len(cars) == 0: cars = Car.objects.filter( user_id=self.user_id, car_type=self.car_type, facture__facture_id=1, ) But I want to do not repeat all the block, and I want to know if there is another way like: Car.objects.filter( user_id=self.user_id, car_type=self.car_type, facture__facture_id=1 | facture__facture_id='1', ) -
django LOGGING - How to change filter attribute name by format
I have the following settings: LOGGING = { 'version': 1, 'disable_existing_loggers': True, 'filters': { 'require_debug_false': { '()': 'django.utils.log.RequireDebugFalse' }, 'some_id': { '()': 'my.special.filter' }, }, 'formatters': { 'json': { '()': 'my.special.formatter', 'format': '%(thread)d\t%(message)s' }, ... the filter add "some_id" to the log so the output looks like this: {"thread": 140155333515008, "message": "some log msg", "some_id": "123456"} I want to modify the additional attribute "some_id", so the output would look like this: {"thread": 140155333515008, "message": "some log msg", "some-id": "123456"} I saw that it can be done with CustomAdapter but I have a lot of "logger = logging.getLogger(...)" so I cant use this. How can i change the output attribute name? -
Why Model Serializer is saving partial data?

The other two fields 'created_by' , 'created_by_ip' is present in my model but I want to fill these column automatically that's why I have not mentioned it in serializer fields , also I don't want to return it after saving the data.

Translation in Django 3.2
I was working in Django 2.2 and for setting up the current user's language I used the session: language = request.user.language request.session[LANGUAGE_SESSION_KEY] = language translation.activate(language) I just updated to Django 3.2 and I am having an issue with this. Apparently this way to set the language had been deprecated. Instead, I use the language cookie name: response = HttpResponse(...) response.set_cookie(settings.LANGUAGE_COOKIE_NAME, language) translation.activate(language) It is working but I need to set this cookie in every single view or even API GET functions to get the data in the expected language. I wonder if there is any way to set the language just once like I used to do. I want to set the language from the backend, not showing any language selector in the front and so on. Thanks!!
