Django using bulk_update to update all records
With 2.2 we now have the option to bulk update: https://docs.djangoproject.com/en/3.0/ref/models/querysets/#bulk-update I have a model with say millions of rows and I want to efficiently update all the records. I am trying to use bulk_update, but which means I still have to load all the model objects in the memory, modify the field one by one and then use bulk update: What I am doing: def migrate_event_ip_to_property(apps, schema_editor): Event = apps.get_model('app' 'Event') events = Event.objects.all() for event in events: if event.ip: event.properties["$ip"] = event.ip Event.objects.bulk_update(events, ['properties'], 10000) Since there are millions of records, can I avoid doing Event.objects.all() and load all objects into the memory even while using bulk_update? -
djang-bootstrap avoid label tag being added when calling `field|bootstrap`
How to avoid label tag being added when calling field|bootstrap. I have the below code filter.py import django_filters from .models import Issue class IssuesFilter(django_filters.FilterSet): summary = django_filters.CharFilter(label="Summary", lookup_expr="icontains") class Meta: model = Issue Views.py def index(request): issues = IssuesFilter(request.GET, queryset=Issue.objects.all()) context = { 'user': request.user, 'message': 'LogedIn', 'filter': issues } return render(request, 'testApp/index.html', context) index.html {% extends "firstPage/base.html" %} {% load bootstrap %} {% load render_table from django_tables2 %} {% load crispy_forms_tags %} {% block body %} <form method="GET"> <table> {% for field in filter.form %} <tr class="table table-borderless"> <td>{{ field.label_tag }}</td> <td>{{ field|bootstrap }}</td> </tr> {% endfor %} </table> <button type="submit" class="btn btn-primary">Search</button> </form> {% endblock %} When I add field|bootstrap I could see the label tag of the field is displayed. Is it possible to remove additional label tag from being added? -
How to filter useing look up method "in or range" and make sure if any of the item in the list is not available then returns empty queryset
My code snippet: filtered_queryset = Model.objects.filter( Q(model_one__status="OPEN") & Q(model_two__date__range=[start_date, end_date]) & Q(model_two__model_three__pk__in=model_three_id_list) & Q(model_two__something_to_sell__gte=F("model_two__already_sold") + requested_amount) ) In the above snippet I want the following line to work such a way that if some date is missing then it should not return others. What actually happens in range/in operator is that if it finds one or more matching data it returns those data in the queryset. But that's not what I need. I need to make sure that if all the date matches then only return the queryset otherwise it should be empty. Q(model_two__date__range=[start_date, end_date]) We can also use "in" operator if the solution for in operator is possible. In this case code snippet will be: Q(model_two__date__in=date_list) -
Django: implement multiple user levels / roles / types
I have been using Django for quite a while but never have I thought of this until now. Currently, I have a project that contains different user levels. Usually, in my past experience, I only developed systems using Django with only two user levels which are superuser and normal/regular user. So my question is what are the effective ways to present these different user levels in the model/database? Here, I'm going to use a school system as an example and also provide some of my initial thoughts on implementing it. User levels: Admin (superuser & staff) Principle Teacher Students Method #1: Add new tables based on each user level from django.contrib.auth.models import AbstractUser from django.db import models class User(AbstractUser): user = models.CharfieldField(max_length = 10, unique = True) class Admin(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) class Priciple(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) class Teacher(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) class Student(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) Method #2: Add additional user types attributes in the User model from django.contrib.auth.models import AbstractUser from django.db import models class User(AbstractUser): user = models.CharfieldField(max_length = 10, unique = True) is_superuser = models.BooleanField(default = False) is_staff = models.BooleanField(default = False) is_principle = models.BooleanField(default = False) is_teacher … -

How to implement an object specific modal in Django?
I'm new to Django and I have a problem moving my stuff to the front end of my website. I want to do fantasy-style website. My main page will display a list of NHL players.

Issue with Hiding Django SECRET_KEY Using environment variables
I am running my programs and Django Project on an AWS EC2 Ubuntu instance in a virtual environment. The django project is run on an apache server. For purposes of this question I will say that my secret key is 'AAAA'. I have an environment variable set ("SECRET_KEY"). It is properly setup, and when I put: import os print(os.environ['SECRET_KEY']) in the python shell, it prints the proper secret key, AAAA. Therefore, I know python is able to access the proper environment variable. In settings.py, when SECRET_KEY='AAAA', the project works, and everything executes properly. However when I change this to: SECRET_KEY=os.environ['SECRET_KEY'] the server doesn't work (500 Internal Server Error). Everything seems like it should work. Any suggestions or ideas on what I missed here? -
using a property method in list_filter in custom admin
I have a model like this: class CustomUser(AbstractUser): @property def is_paid(self): return self.apayment4thisuser.all().filter(expirydate__gt=timezone.now().date()).count()>0 in the customadmin I am able to add this under my list display, but it is throwing error when I add it to my list filter: class CustomUserAdmin(UserAdmin): model = CustomUser list_filter = ['app_user','is_paid'] list_display = ['id', 'username', 'email', 'is_paid', ] This is the error: ERRORS: <class 'users.admin.CustomUserAdmin'>: (admin.E116) The value of 'list_filter[1]' refers to 'is_paid', which does not refer to a Field. I was wondering is there not any way to add this to list_filter? Thanks,
