Mess with models primary key. Django
There are two models: class Parent(models.Model): name = models.CharField(max_length=25) date = models.DateField(default=now) class Child(models.Model): name = models.CharField(max_length=25) quantity = models.DecimalField(max_digits=10, decimal_places=2) parent = models.ForeignKey(Parent, on_delete=models.CASCADE) In my app I have a set (or list) of parents within a set of child elements inside. When I try to delete child element - request redirects me to the wrong parent. Here below my view: def deleteChild(request, pk): child= get_object_or_404(Child, pk=pk) parent= get_object_or_404(Parent, pk=child.parent.pk) if request.method == 'POST': child.delete() return redirect('detail', pk=parent.pk) context = {'parent': parent.pk} return render(request, 'parent-detail.html', context) my url: path('child-delete/<int:pk>', views.deleteChild, name='child-delete'), I assume one of the reasons are - incorrect ID pass... Point me please what is wrong with this and much appreciate to You All if You give me an advice how to correctly prescribe Models for such case (maybe best practice if any). Because I expect same issue when I start doing updateChild view X))). Thanks a lot and have a nice day! -
ReactJS with Django Elements Displayed As Text
I try to get elements inside my div but they are displayed as text and not Elements. I use Django as the back-end and ReactJS as a link import in my HTML template on the front-end. my template is like this: {% load static %} <!DOCTYPE html> <html lang="en"> <head> <script src="https://unpkg.com/react@18/umd/react.development.js" crossorigin></script> <script src="https://unpkg.com/react-dom@18/umd/react-dom.development.js" crossorigin</script> </head> <body> <div id ="form-container"> </div> <!-- Bootstrap JS CDN --> <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/js/bootstrap.bundle.min.js" integrity="sha384-MrcW6ZMFYlzcLA8Nl+NtUVF0sA7MsXsP1UyJoMp4YLEuNSfAP+JcXn/tWtIaxVXM" crossorigin="anonymous"></script> </body> <script src="{% static '/js/login.js' %}"></script> </html> and my react JS file is like this: const hello = ('<h1>test</h1>'); const root = ReactDOM.createRoot(document.getElementById("form-container")); root.render(hello); Have tried removing the ' ' or the parenthesis but can't get it to work it either it shows invalid syntax. -
Austi updating Django postgres database when changes in legacy database are made in a docker container
I'm working on a Django project with docker which use different legacy Microsoft SQL Server database. Since I didn't want to alter those legacy databases I use inspectdb and Django router to create models and then use the data there to read and write a default Postgres database with all the Django specific tables. Everything was working fine, each instance of my model objects have the initial data from the SQL server db populating into the Postgres db. However whenever anything is updated in the SQL server db the data in the is not updating in Postgres db unless the docker container is stop and restarted. I'm wondering is there a way to autoupdate my postgres db when changes are made in the connected SQL Server db's with stopping the container? Would I need to use something like celery or a cron job to schedule updates? I've used cron jobs before but only to pull from an api. Is it possibly to run celery or a cron job just on a database and not an api? Or is there a solution that's simplier? I'm also running with nginx and gunicorn on an Ubuntu server. Using volumes to persist db. -

Django Files doesn't save
I want to do a django project where you upload an image and this image is displayed on another page. I can edit it only with admin panel. Here is the code: Views.py def home(request): all1 = New.objects.filter(username='mynameis12').all() if not request.user.is_authenticated: return redirect('/login/') return render(request, 'home.html',{'alls':all1}) Models.py class New(models.Model): username = models.CharField(max_length=200) image = models.ImageField(upload_to='media') Forms.py class New1(ModelForm): username = forms.CharField(max_length=200) image = forms.ImageField(required=False) class Meta: model = New fields = ['username','image'] The image is showed but it doesn't be saved. What should I do? Thanks. -
Non FK models tied together by ID (unmanaged model) - how to filter in Django?
I have two models that are related - but they are not a FK relationship in Django because one is a non-managed model with the data coming from a pre-populated DB table. class Enrollment(models.Model): id = models.IntegerField(db_column="ID", primary_key=True) location_id = models.IntegerField(db_column="locationID") grade = models.CharField(db_column="grade", max_length=10) class Meta(object): managed = False db_table = "mytable_Enrollments" class Location(models.Model): name = models.CharField(max_length=50) alternate_name = models.IntegerField() I'm trying to filter Enrollment models using a list of Location models - but they are not tied together in a FK relationship. I am trying to get enrollments for a particular location like this: # This does not work properly - but does not hit the db which is what I want location_ids = Location.objects.filter(id=1).values_list("id", flat=True) enrollments = Enrollment.objects.filter(location_id__in=location_ids) However, this returns an empty queryset. If I cast location_ids to a list (like this: list(location_ids)) and then filter on that, it works. # This works properly - but hits the db which is NOT what I want location_ids = Location.objects.filter(id=1).values_list("id", flat=True) enrollments = Enrollment.objects.filter(location_id__in=list(location_ids)) Is there a way to use the Django ORM to get what I want in this case without causing it to evaluate the queryset? -

Django: query of a foreign key of a foreign key
This might be stupid question and I am sure that there is a basic query for this situation, but I don't seem to get a hang of it and Google turned out to be a miss for solution. I have models: Project, primary key=project_no; Under project there are product_config models, primary key=id; Under each product_config there is a pre_config model, primary key=product_id; Under each pre_config there is a list of sub_config models, primary key=id; Now I am loading a page for project details and I pass a project_no and make a query for all product_configs: project.objects.get(project_no=project_no) product_config.objects.filter(project_no=project_no) Now I want to create a table for the list of sub_configs according to pre_config under product_config. In a shell I can query the list with: sub_config.objects.filter(product_id=product_id) How I can pass the product_id of pre_config from my product_config to query all the sub_configs? -
DJANGO: Running SQL query using cursor in project.settings.py file
In my project, I have made some setting fields within the "settings.py" file configurable by exposing them to the user via an environment file. So the user can modify the values on the .env file, and that is then used to update the setting fields within the main project settings.py file. I want to improve this by migrating some of this values to the database, so users can set their values interactively via the product's UI instead of having to modify the .env. I have taken the following approach: After the default database has been declared in the DATABASES dictionary, I isntantiate a connection.cursor() to run a raw SQL query that retrieves the settings from the database, as described in the documentation. I manipulate the results of the cursor to construct a dictionary in which keys are setting identifiers and values are the relevant values from the database, as set by the user. This dictionary is then used to assign the appropriate value to each Django setting variable (i.e. SESSION_COOKIE_AGE, MEDIA_ROOT, etc.). So at each setting variable instead of doing a getenv, I retrieve the value from the dictionary using the relevant key. I have observed the code's behavior within … -

Recursively navigating through dictionnary in django template
I have a dictionnary of unknown depth which I want to display in my Django template. This dictionnary represents the structure of the subfolders inside of a folder. My goal is to display it with the parent subfolders before their children, which would be indented to show that they're children of that folder. So to explain with an example, if I have the following dictionnary : {'Script Hello': {'Script Hello World': {'Script Hello World 2': None, 'Script Hello World 3': None}}, 'Script Hello World 4': None, 'Script Hello World 5': {'Script Hello World 6': None}} I want it to be displayed like this : . Script Hello . Script Hello World . Script Hello World 2 . Script Hello World 3 . Script Hello World 4 . Script Hello World 5 . Script Hello World 6 I've done a small code that does the job if the depth if at most 3 (to determine what I really wanted), but couldn't find a way to make it recursive. My code is this : {% for key, values in list.items %} <li> {{ key }} <ul> {% for key,values in values.items %} <li>{{ key }}</li> <ul> {% for key,values in values.items %} … -
Django celery .delay() in requests get stucked
I have a project running on 3 different environments, on 2 environments it works on production for some reason stopped working (was working before). The code is pretty simple I have a view which runs a task in delay and should return immediately some message to the user: class PrintTaskView(View): def get(self, request): logger.debug('ABOUT TO ADD A TASK') tasks.print_task.delay() logger.debug('TASK WAS ADDED') messages.info(request, _('Print task added to queue')) return HttpResponseRedirect(reverse_lazy('admin:index')) I am so confused because this works smooth on my local machine and on the test environment while on production request gets stuck on loading after the first log has been executed. What is even more confusing is that if I run the code from the shell (manage.py shell) then the print task gets created and picked up by a worker and executed. Also celery beat tasks runs smoothly. My celery settings: # Celery CELERY_BROKER_URL = os.getenv('CELERY_BROKER_URL') CELERY_RESULT_BACKEND = os.getenv('CELERY_RESULT_BACKEND') CELERY_BEAT_SCHEDULE = { ... } website/__init__.py from __future__ import absolute_import, unicode_literals from .celery import app as celery_app __all__ = ('celery_app',) celery.py from __future__ import absolute_import from celery import Celery from django.conf import settings app = Celery('somename') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks(lambda: settings.INSTALLED_APPS, related_name='tasks') Any idea or suggestion is more than welcome :) -

Correct way to deactive user and its profile in Django
I have created a view where the logged-in user should be able to deactivate its profile. I expect then to see the change being reflected in my admin section, but it's not. Looks like the user is being deactivated but the user.profile isn't. I am puzzled since, after I did a whole project following Django docs, the way to properly manage user deactivation seems missing. I'd like to stay strict to Class-Based-Views.

Django + GUnicorn ASGI with SCRIPT_NAME
I have a django application running with a gunicorn ASGI server and a NGINX reverse proxy for serving static content. All packaged within a docker container. Now I want to serve this container behind a reverse proxy with a path prefix, e.g. "mydomain.com/djangoapp/". The problem is, that django doesn't know it's hosted under a subpath and for example the django admin application then aleays redirects to the root path "/" instead of "/djangoapp/". I already read that there are several settings which handle this problem. I tried setting the "FORCE_SCRIPT_NAME" in the django settings directly to "/djangoapp". It worked for the admin login page, but after clicking the login button it redirected to the wrong root "/". I tried setting the "SCRIPT_NAME" environment variable of the gunicorn server to "/djangoapp". It did not apply at all. I'm running now out of ideas what else to try. Does anybody else have a solution for this problem? -
