Deploying my project - help me

hi there I want to design a personal website with django, and illustrate some other mini projects, which are designed in other programming languages, in that site. for example a calculator in c or c++. the calculator should be worked in the site. however, i don't know that the code of calculator should be merged with the code of django? or it can be uploaded through admin panel?

Hey i have a django package and it doesn't have manage.py to run it. Does anyone know how can i debug it or run it?

A "django package" can be an app that need to be installed on a django project, you need to be more specific

https://github.com/ali-zahedi/az-iranian-bank-gateways This is the package i want to debug

Hi there! I have a question. How do I restrict the management of posts? (for example, only the administrator and the author of the post can edit and delete a post?) Are there any ready-made solutions or mixins?

It has instrucctions

You can easily do that yourself. In the management view, you should filter posts which the current user created

That's for the time you want you use it on another project. I want run itself

Build a sample app and install it there

But another user can type, for example, url post/delete/1 and delete it. I want to get 403, if user is not admin or author of the post

In your view, get the user in the context, check if it's the user that created the post, if not then you return appropriate response

How pass two function parameters in the template?

I need help in ajax

Hello, I need to save the users who created a model objects from a form automatically. I have following field in model. created_by=models.ForeignKey(User, on_delete=models.CASCADE) How can I get users from the form?

Okay. the method which renders form has login decorator already. After if form.is_valid(): how to assign logined user to created_by model field?

If you are using CreateView, modify the is_valid(self, form) form.instance.created_by = self.request.user

If you are using CreateView, modify the is_valid(self, form) form.instance.created_by = self.request.user

No. I'm using FBV

i'm getting self not defined error

Hi guys, I want to deploy a docker container to heroku. Any ideas?

Do you have tracking devices sending device locations to your Django app already (Streaming longitude and latitude that is)

the documentation seems cumbersome to me

Hello everybody! The problem is the following: there is a "User" model added to admin.py (code - http://hastebin.com/ofuhucekiq.py). There is a function that allows you to download data from this model in csv format in the django admin panel. This function does not work quite correctly, the reason: in the "User" model there is a "status" field, which is a foreign key to the "Status" model. And there is such a case when the "status" field in the "User" model can be null. Accordingly, if I try to download a file with data in which "User.status == null", I get an error, because in the above code, in the "download_csv()" function, I try to access the current_status field in the status model through foreign key. Is there any way to avoid this?

in big projects , often def used or class

For every object in the queryset passed to your action, check if the status is None. If it is None, continue, else do your normal logic

"Field 'roll' doesn't have a default value"

just read and realize

When i set for handling default it doesn't work

class Service(Model): number = CharField bill = ForeignKey(Bill, related_name="bill_services") price = IntegerField bills = Bill.objects.prefetch_related('bill_services').annotate(service_number_with_max_price=....) Hello. How can I annotate a service number with max price for each Bill?

.aggregate(max_price=Max('bill_services__price'))

so then I can iterate thought bills and get service number with biggest price for each bill
