How to make a dependent combo loading work when CreateView is used in django?
I have a Project Model. And I have a Feature model which has the Project model as foreign key. Now I have a StatusUpdate model, which has both Project model and Feature model as the Foreign keys. Now on a StatusUpdate create page, only the feature names of the selected project name should be loaded, when we select a project name. Models: class Project(models.Model): project_name = models.CharField(max_length=100, unique=True, verbose_name='Project Name') from projects.models import Project class Feature(models.Model): feature_name = models.CharField(max_length=100, verbose_name="Feature Name") project_name = models.ForeignKey(Project, verbose_name="Project Name", on_delete=models.CASCADE) from features.models import Feature from projects.models import Project class Statusupdate(models.Model): project_name = models.ForeignKey(Project, verbose_name="Project Name", on_delete=models.CASCADE) feature_name = models.ForeignKey(Feature, verbose_name="Feature Name", on_delete=models.CASCADE) forms.py from .models import Statusupdate class StatusupdateModelForm(forms.ModelForm): class Meta: model = Statusupdate fields = ['project_name', 'feature_name''] widgets = {'project_name': forms.Select(attrs={'class': 'form-group form-control col-sm-10 '}), 'feature_name': forms.Select(attrs={'class': 'form-group form-control col-sm-10'}) } urls.py from django.urls import path from .views import ( StatusupdateCreateView, StatusupdateDeleteView, StatusupdateListView, StatusupdateUpdateView, StatusupdateDetailView ) app_name = 'statusupdate' urlpatterns = [ path('', StatusupdateListView.as_view(), name='status-list'), path('create/', StatusupdateCreateView.as_view(), name='status-create'), path('<int:id>/', StatusupdateDetailView.as_view(), name='status-detail'), path('<int:id>/update/', StatusupdateUpdateView.as_view(), name='status-update'), path('<int:id>/delete/', StatusupdateDeleteView.as_view(), name='status-delete'), ] StatusUpdate CreateView from .models import Statusupdate from .forms import StatusupdateModelForm class StatusupdateCreateView(LoginRequiredMixin, CreateView): template_name = 'statusupdate/status_create.html' model = Statusupdate form_class = StatusupdateModelForm def form_valid(self, … -
how to loop through a condition in Django template
I'm attempting to display "you don't have active investment" just when there are no investments, however I've discovered that whenever the loop runs, it displays the same message regardless of whether or not there are any investments. I believe I have given enough information to anyone who is willing to give it a trial. The code snippet is below, along with a screenshot at the bottom. <h1 class="md:ml-[11.5em] mt-7 mb-0 font-bold"> Active Plan</h1> {% for investment in investments %} {% if investment.is_active == True %} <div class="row justify-center my-5 md:my-3"> <div class="col-md-9 border-2 border-gray-300 rounded-lg"> <div class="pricing-table-item bg-athens-gray px-4 md:py-0"> <div class="space-y-10 md:flex justify-between items-end"> <div> <h1 class="font-bold capitalize" style="font-family: Open Sans;">{{investment.plan}}</h1> <div class="text-sm my-2" style="font-family: Open Sans;"><span class="text-gray-400">Invested Amount -</span> <span class="font-bold">{{investment.deposit_amount}} USD</span></div> </div> <div class="flex justify-between align-items-center"> <div> <h1 class="font-bold capitalize" style="font-family: Open Sans;">{{investment.created_at}}</h1> <div class="text-sm my-2 text-gray-400" style="font-family: Open Sans;">Start Date</div> </div> <div class="ml-3 mr-3"> <i class="fa-solid fa-arrow-right-long text-gray-400"></i> </div> <div> {% if investment.plan == "Basic - Daily 2% for 180 Days" %} <h1 class="font-bold capitalize" style="font-family: Open Sans;">{{investment.due_date}}</h1> {% else %} <h1 class="font-bold capitalize" style="font-family: Open Sans;">{{investment.due_date}}</h1> {% endif %} <div class="text-sm my-2 text-gray-400" style="font-family: Open Sans;">End Date</div> </div> </div> <div class="md:flex justify-center items-center"> <div> {% … -
I have a project how to deploy it to different servers automatically?
I have a project that created with django. I finished it and deploy it to a ubuntu server but someone want to deploy this project to in own ubuntu server and it is take much time to up this project in a server as you know. So I wonder about is there any way to deploy a product automatically like with bash script file or python script file. I want to give an instance for what I really want. As you know there is nothing inside a new server. So my project has requirements like docker, postgresql etc. I want to write a script that install all requirements, create a database or what I wish.

How can I split deployments of Django apps in the same project with shared models and database?
I have an architectural question: We have a Django project made of multiple apps. There is a core app that holds the main models used for the other sets of apps. Then, we have a couple apps for user facing APIs. Lastly, we have some internal apps and tools used by developers only that are accessible in Admin UI as extended features. Our deployment process is very monolithic. We use Kubernetes and we deploy the whole project as a whole. Meaning that if we only had changes in an internal app and we need that in production, we will build a new Docker image and deploy a new release with a new version tag incremented. I'm not a big fan of this because change in internal tools shouldn't create a new release of the user facing applications. I have been wondering if there is a way to split those deployments (maybe make them into a microservice architecture?). So we could deploy the user facing applications separate from the internal tools. I know I could build separate images, tags and everything for parts of the project but I'm not sure how they could communicate between each other if internal_app_1 depends on … -

Probably a very basic question: can I build and maintain the same website (in Django) from both Windows and macOS?
Disclaimer: First, I apologise if I'm incorrectly applying technical terms here or, worse, completely misunderstanding things. I'll edit if corrected. Context: Lately I've been building and deploying some basic website ideas to Heroku using the Django framework. I've been doing this on Windows, using venv as my virtual environment "wrapper". I've been building these exclusively from the command line interface. I also have a MacBook that I'd like to use to access and manage those websites, and in future, larger projects. I would prefer not to install Windows on this MacBook. To be clear, I know that it's possible to build and deploy a website using Django and Heroku on macOS. I know there are, at the very least, some syntactical differences in how I would approach this from the CLI versus Terminal. Desired outcome: I would like to set up a website in the fashion indicated above on Windows or macOS, and then access and manipulate it from the other OS. Questions: Is this possible? (Or if I set it up on Windows must I only use Windows to manage it?) If I set up a website in this fashion using Django, Heroku, and venv on Windows, how (if … -
Get value list from ManytoMany Queryset
I have two models Bookings and Presenter, which are setup as a Many to Many Field. I then have a function called 'export excel' (found on online tutorial) , which exports all of the data from the Booking model to an Excel spreadsheet. Each booking may contain more than one presenter. Currently the export works but displays a new record for bookings that have more than one presenter assigned. Is it possible to get the presenter name be displayed as a list? rather than duplicating the booking on a new row. So for example if booking 1 contains two presenters the names will display as ['mark', 'jake'] Queryset used in export excel function rows= Bookings.objects.all().exclude(status='Cancelled').values_list( 'id', 'program_type', 'delivery_method', 'booking_date', 'booking_time', 'duration', 'school_name', 'year_level', 'street', 'suburb', 'post_code', 'contact_name', 'email', 'phone_number', 'comments', 'students_attending', 'status', 'presenter__name') Models class Presenter(models.Model): id = models.BigAutoField(primary_key=True) name = models.CharField(max_length=80) email = models.EmailField() phone_number = models.CharField(max_length=10) role = models.CharField(max_length=50) def __str__(self): return self.name class Bookings(models.Model): statuses = [ ('TBC', 'TBC'), ('Confirmed', 'Confirmed'), ('Completed', 'Completed'), ('Cancelled', 'Cancelled'), ] id = models.BigAutoField(primary_key=True) program_type = models.CharField(max_length=40) delivery_method = models.CharField(max_length=40) booking_date = models.DateField() booking_time = models.CharField(max_length=10) duration = models.CharField(max_length=10) school_name = models.CharField(max_length=120) year_level = models.CharField(max_length=10) street = models.CharField(max_length=120) suburb = models.CharField(max_length=120) post_code … -

How to create a custom migration to change the inbuilt django User model
I am having this problem in creating a custom User model in django and i actually posted this question before and I did get an answer from "@Sorin Burghiu" and it was very helpful since I did not even know the issue before but now I do know the issue but I don't know how to write my custom migration to do so let me post the answer here "Changing the user model mid-project is a difficult situation if you are trying to override the existing user model with a NewUser. Reference You will need to write a custom migration to do it to transfer all data from the current User table to the NewUser table, then drop the User table safely. If that's not the case and you just started the project, feel free to drop your current database and make migrations again after changing the default user model in settings.py (you are doing that already). Also make sure all imports in other files are undated to use your NewUser model instead of the django default User."

I already have a django app running on elastic beanstalk but its health is in red condition and also its debug mode is set to True. I tried shooting postman APIs locally, it works with http://127.0.0.1:8000. but it doesn't with http://my-eb-site:8000 . How do I configure my elastic beanstalk django backend for production? Also how would i face CORS issue later on?
