I would like to create my own database which will contain a People table where usernames and passwords will be stored. I have to create my own model by inheriting from AbstractBaseUser appLogin/models.py class Sector(models.Model): jobName = models.CharField(verbose_name = "jobName", max_length=50) idSector = models.CharField(verbose_name = "idSector", max_length=50, primary_key=True) class Meta: db_table = "Sector" class People(AbstractBaseUser): firstName = models.CharField(verbose_name = "firstName", max_length=20) name = models.CharField(verbose_name = "name", max_length=20) regNumber = models.CharField(verbose_name="regNumber", max_length=20, primary_key=True) idSector = models.ForeignKey(Sector, on_delete=models.CASCADE) USERNAME_FIELD ="regNumber" REQUIRED_FIELDS = ["firstName", "name"] objects = UserManager() class Meta: db_table = "People" appLogin/admin.py from django.contrib import admin admin.site.register(Secteur) project/settings.py AUTH_USER_MODEL="appLogin.People" After having done this, i don't have the tables in the db.sqlite3 python manage.py makemigrations python manage.py migrate -
Django smart selects doesn't work with JS cloning
I'm trying to create a page with ability to add any amount of form-copy. I use django-smart-selects to make my form's field chained. It works fine if I have only 1 form on page. Then I'm using javascript to make a function to clone form instance by pressing button and addind new form's ids to these clones. The problem is when I press "+" button I get new cloned form on page, but chained-selection doesn't work anymore, and it seems that this clone copying all my choices from the firs form and remembering this state.

ValueError: Cannot assign "1": "LeadFacilityAssign.assigned_facilities" must be a "Facility" instance
I've been trying to create an api endpoint to update my "lead" objects and add a list of facilities to them when sending a put request (each time a different amount of facilities). The lead objects already exist inside the database so do the facility objects. Since i need a date and time associated to each facility when they are being added to a lead i created the "LeadFacilityAssign" class. Since i wasn't able to get it to work i tried to do it just with a post request for now, during the lead creation process. I was told that i need to use bulk_create if i need to add more than one facility this way. I couldn't find anything on bulk_create inside the drf documentation so i decided to do this for now just with one facility and improve my code from there one issue at a time since i'm new to drf. Does anyone know what is causing this error? I tried a few different things but nothing worked so far.

SQL to Django ORM for group by with distinct

Django, CORS "Access-Control-Allow-Origin" error

How to populate checkboxes in a table with values from a Django model
My html table has a column that contains a checkbox. The user can check or uncheck it. The value (boolean) is stored in the Django model Subscriber under Subscriber.participates. All objects of Subscriber are imported into the HTML using a Django view (context = {'subscribers' : Subscriber.objects.all(),}). When loading the table, the checkboxes must be set to the correct value. To that purpose I have written a javascript function, which is invoked in the <input> element. However, the checkboxes all remain unchecked, though I have verified through /admin/ in Django that some of the values in the dbase are indeed "TRUE". firstName and lastName load without any problem into the table. What did I do wrong? <head> <meta charset="UTF-8"> <title>Participants</title> <script> function checkBox() { if({{ x.participates }}){ document.getElementById("checkbox").checked = true; } else { document.getElementById("checkbox").checked = false; } } </script> </head> <body> <table> {% for x in subcribers %} <tr> <form action="updateSuscribers/{{ x.id }}" method="post"> {% csrf_token %} <td>{{ x.firstName }}</td> <td>{{ x.lastName }}</td> <td> <input id="checkbox" type="checkbox" name="participates" onload="checkBox()"> </td> </form> </tr> {% endfor %} </table> </body> -

Multiple try except in a serializer Django
I have a Warehouse model like the following: class ShelfBin(models.Model): bin_id = models.IntegerField(default=0) bin_name = models.CharField(max_length=50, default=0) class UnitShelf(models.Model): shelf_id = models.IntegerField(default=0) shelf_name = models.CharField(max_length=50, default=0) bin = models.ManyToManyField(ShelfBin, blank=True) class AisleUnit(models.Model): unit_id = models.IntegerField(default=0) unit_name = models.CharField(max_length=50, default=0) shelf = models.ManyToManyField(UnitShelf, blank=True) class ZoneAisle(models.Model): aisle_id = models.IntegerField(default=0) aisle_name = models.CharField(max_length=50, default=0) unit = models.ManyToManyField(AisleUnit, blank=True) class WarehouseZone(models.Model): zone_id = models.IntegerField(default=0) zone_name = models.CharField(max_length=50, default=0) aisle = models.ManyToManyField(ZoneAisle, blank=True) class Warehouse(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE) name = models.CharField(max_length=250, default=0) address = models.CharField(max_length=500, default=0) zones = models.ManyToManyField(WarehouseZone, blank=True) for this I have created a serializer like the following: class WarehouseSerializer(serializers.ModelSerializer): zones = WarehouseZonesSerializer(many=True) class Meta: model = Warehouse fields = "__all__" def create(self, validated_data): print("validated data warehouse", validated_data) zone_objects = validated_data.pop('zones', None) instance = Warehouse.objects.create(**validated_data) for item in zone_objects: aisle_objects = item.pop('aisle') wz_obj = WarehouseZone.objects.create(**item) for data in aisle_objects: unit_objects = data.pop('unit') za_obj = ZoneAisle.objects.create(**data) for u_data in unit_objects: shelf_objects = u_data.pop('shelf') au_obj = AisleUnit.objects.create(**u_data) for s_data in shelf_objects: bin_objects = s_data.pop('bin') us_obj = UnitShelf.objects.create(**s_data) for b_data in bin_objects: b_obj = ShelfBin.objects.create(**b_data) us_obj.bin.add(b_obj) au_obj.shelf.add(us_obj) za_obj.unit.add(au_obj) wz_obj.aisle.add(za_obj) instance.zones.add(wz_obj) return instance Now the problem is that sometimes warehouse can have zone, aisle, units, etc(all 5 sub-levels) but sometimes it can only be 1,2 … -
How does multiple user types logging in & out work in a live environment? [Django]
I have a web app that has two different user types, Nurses and Doctors, and they can both log in and out. I opened two tabs and logged in as a Nurse in one tab and as a Doctor in the other. However, when I log out of either one of those tabs, the other will be automatically logged out as well. I have read this link How can made multiple user login at same time in same browser in django project and understand why this happens. I know that I can work around it by logging in from different web browsers and by using Incognito mode. However, how do I code it such that in a live environment, users can actually logout without logging other users out? -
Increase django fixed value
In my Django project, there is a fixed number in one of the html input fields and I want this number to increase every time the form is opened. But since it will increase every time the form is opened, it is necessary to get the value of the last data from the database in that field. How can I apply something like this?
