Containers in pod won't talk to each other in Kubernetes
I have three containers in a pod: nginx, redis, custom django app. It seems like none of them talk to each other with kubernetes. In docker compose they do but I can't use docker compose in production. The django container gets this error: [2022-06-20 21:45:49,420: ERROR/MainProcess] consumer: Cannot connect to redis://redis:6379/0: Error 111 connecting to redis:6379. Connection refused.. Trying again in 32.00 seconds... (16/100) and the nginx container starts but never shows any traffic. Trying to connect to localhost:8000 gets no reply.

No related, column doesn't exist, None by None
Good night. Can someone explain me what happened in my situation? I have models and databases. When I decided to add some additional field in development, I often have issues like in the title of the question. So what I was doing to fix this. I'm using migrate --fake and deleted with migrations and returned back again with migrations. Obviously it works, but I still can't understand this magic.) But ok it works for me. When I deployed the code in production it displayed me again this errors. And I repeated the steps for production. It can be OK for me, but today I lost my data, it transformed into None by None. Is it because I add to new fields such attributes like null=True, blank=True? Or it happened because I have issues with migrations and I often faked them? -
Pass data from one form to another one in Django forms/views
I'm not too knowledgeable in Django, but I wanted to implement this idea that I have but I can't seem to think how to get there. Now, on my web app, there is a form with a field called "contractor", and it has a button which, when clicked, opens a modal with another form with different fields about the "contractor". I would like it to, when information is submitted about the contractor in the second form, it autofills the field in the first form with the data from the first field of the second form. Also, I want to make it so that when the user starts typing in that "contractor" field in the first form, already submitted data can be chosen. I leave my code here to give you an idea: models.py class Contratos(models.Model): name=models.CharField(max_length=30) contractor=models.ForeignKey(Vendors, on_delete=models.CASCADE, to_field='contractee_vendor') contractee=models.CharField(max_length=30) [......] class Vendors(models.Model): contractee_vendor=models.CharField(max_length=30, unique=True) company=models.CharField(max_length=30) description=models.TextField() [......] views.py def ContractView(request): form=contractsform(request.POST) if form.is_valid(): con =form.save() return redirect('contracts', con.id) else: form = contractsform() return render(request, 'contform.html', {'form': form}) class VendorsModal(BSModalCreateView): template_name = 'vendform.html' form_class = vendorsform success_message = 'Success: Vendor created' success_url = reverse_lazy('new-contract') from my contracts HTML to open modal <form action="" method=POST> {% csrf_token %} <label for="{{ form.subject.id_for_label … -
Django 4.x - Conditional QuerySet for Pagination and a many-to-many relationship
Disclaimer: I have searched and a question tackling this particular challenge could not be found at the time of posting. The Requirement For a Class Based View I need to implement Pagination for a QuerySet derived through a many to many relationship. Here's the requirement with a more concrete description: Many Library Records can belong to many Collections Web pages are required for most (but not necessarily all) Collections, and so I need to build views/templates/urls based on what the client identifies as required Each Collection Page displaying the relevant Library Records requires Pagination, as there may be 100's of records to display. The First Approach And so with this requirement in mind I approached this as I normally would when building a CBV with Pagination. However, this approach did not allow me to meet the requirement. What I quickly discovered was that the Pagination method in the CBV was building the object based on the declared model, but the many to many relationship was not working for me. I explored the use of object in the template, but after a number of attempts I was getting nowhere. I need to display Library Record objects but the many to many … -

Way to display user adjustable shapes on webpage in Django
I'm new to Python, and am currently working on web development in Django. I need to have an interface on this website that allows a user to dynamically adjust a rectangular shape that displays this adjustment to them on the website in real time. Does anyone know how I can integrate this using Django or Bootstrap. Pretty much I need a way to display to the user a rectangle that they can drag and drop the lengths of on the screen as they desire. Very similar to the MS Word shape drawing tools where the user can pick the edge of and expand or collapse. -
