hi, i am using django with heroku, when i make change in local repository and then make deploy, my database (user) goes missing or returns to the way it was.
is there a way to pull database from heroku to local repository ?
Since you are using Heroku, the data isn’t going to persist if you use Sqlite or FileSystem.
You need to connect a proper MySQL or Postgres DB and connect them. Just use the Heroku one it’s easier.
But do be aware later this year Heroku will stop their free plans, all are paid.

How to join between form and sqlit3 database ?😞

Good morning, is it possible to create a project in Django with applications and that the clients only need to access the administration panel?
Applications:
Invoices, Reports, Contracts.
10 workers and 1 boss who I will give the ability to handle the workers.

Applications:

10 workers and 1 boss who I will give the ability to handle the workers.
You want a user that can only access the admin panel but not the application? Does not make that mich sense to me.
But sure you can create such a project

I want give one admin user of the admin panel to the boss and that way he can create the user to the workers and want everybody loguin to the admin panel and work there
Forrest
All the workers and the boss add data and make stuff in the admin panel

Yes you can.
Though I would not give all those users access to the admin panel. But that’s me.
I would let the boss be the superuser and the one that has access to the admin panel.
And create separate maintenance overviews/forms/templates for the other users to enter their data.
Why: the Django Admin panel can be very destructive

With a little creativity you can convert the project from the main tutorial from a Poll/Voting project into an Invoice processing project

My goal is save the time i spend in use Bootstrap and give format to the templates and forms because iam learning Django and not have a much time

I'm going take the risk, another question is necessary the templates if i make all in the admin panel ?

You mean;
a) include the django-tabulate project in your code
b) use TabularInline from Django itself
?

This is full query:
select vehicle_id, firmware
from (
select vehicle_id, firmware
from vist_core_onoffevents
where time > to_date('2022-06-01','YYYY-MM-DD') and event_type_id=10
order by id desc
)
group by vehicle_id, firmware

where time > to_date('2022-06-01','YYYY-MM-DD') and event_type_id=10
order by id desc
)
group by vehicle_id, firmware
It’s something like;
queryset = VisitCoreOnoffevents.objects.filter(time__gte=date(2022, 6, 1)).only(“verhicle_id”, ”firmware”).order_by(“-id”).group_by(“vehicle_id”, ”firmware”)
https://docs.djangoproject.com/en/4.1/ref/models/querysets/
Koen de
Edit; minus “id” for descending sort
Koen de
It’s something like;
queryset = VisitCoreOnoffevents.objects.filter(time__gte=date(2022, 6, 1)).only(“verhicle_id”, ”firmware”).order_by(“-id”).group_by(“vehicle_id”, ”firmware”)
https://docs.djangoproject.com/en/4.1/ref/models/querysets/
You can try for yourself;
First get a handle to the correct Model. And all objects; Model.objects.all()
Then append the filter
Third; play around with .only() and .order_by() and .group_by()

Yes.
It has been asked and done before.

Or https://medium.com/coinmonks/how-i-integrated-django-with-blockchain-and-built-a-decentralized-application-dapp-f104ae551e12
I am happy to see your efforts so far

Can you show us the querset param and get_queryset method from your ViewSet?
Views.py
class CategoryList(ListView):
model = News
context_object_name = 'news'
allow_empty = False
template_name = 'dashboard/news/dash-category.html'
def get_context_data(self, *, object_list=None, **kwargs):
context = super().get_context_data(**kwargs)
context['categories'] = Category.objects.get(url = self.kwargs['slug'])
return context
def get_queryset(self):
return News.objects.filter(category__url = self.kwargs['slug'], moderation = True)
wayne
What happens when allow_empty=True ?
But I need that when a user enters an incorrect URL in "category", 404 is output, not 500
Koen de
Pitifully...
It is what it is. https://docs.djangoproject.com/en/4.1/ref/class-based-views/mixins-multiple-object/#django.views.generic.list.MultipleObjectMixin.allow_empty

Is it possible to remove the category that shows 404?

You can implement anything you want in get_queryset to make sure it returns the same when the category is empty or when someone searches for something non-existent

Your question is not related to Django.
If it's a Python related question go to @Python group, otherwise please move to @PythonOfftopic group and ask there.
Koen de
Friends, any of you know how to consume the MSTeams api with python or an example
Yeah check pypi.org. There are at least four projects for MSTeams.
Also Microsoft has an excellent tutorial about it https://docs.microsoft.com/en-us/azure/communication-services/quickstarts/chat/get-started?pivots=programming-language-python
