Django delete item use case : good practice?
Little general explanation. I'm pretty newbie in Django, I have a little knowledge, but nothing as experience. The code that I want ask about is working, but I have a question about good/bad practice. Does my approach is good or at least not bad? Little use case explanation. I have a site with the items. There is a functionality to add the items and now I want to add a possibility to delete the item. Use case : on the page of item user clicks on the button Delete, we will show a page with details about this item and the button "Confirm delete" at the bottom. If user click on the button I delete this item from database. So I create in urls.py path('item/delete/<int:id>/', views.delete_item, {}, 'delete_item'), I create in views.py def delete_item(request,id): if id : cur_item = get_object_or_404(Item, pk=id) else : raise Http404 if request.POST: try : post_item_id=int(request.POST["pk"]) except ValueError : messages.error(request,"Wrong id number") return render(request, 'myapp/item_delete_form.html', {'cur_item': cur_item}) if (request.POST["delete"] == "yes") and (post_item_id == id): Item.objects.filter(pk=id).delete() # Delete was successful, so redirect to another page redirect_url = reverse('items') return redirect(redirect_url) else: messages.error(request, "id number in form not the same as in URL") return render(request, 'myapp/item_delete_form.html', {'cur_item' … -
How to get parent model in child serializer without using depth?

Celery no longer connecting to Redis through Heroku
I had my Redis server set up and deployed on Heroku and Celery was fully functional however now it does not want to connect. The host and port recently updated but I have switched this over to my code like I usually do to fix the issue but it still persists. [2021-04-22 09:01:46,999: ERROR/MainProcess] consumer: Cannot connect to redis://:host:port//: Error while reading from socket: (54, 'Connection reset by peer'). My celery is set up as follows and the credentials all match with those on Heroku - os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myapp.settings') app = Celery('myapp') app.conf.timezone = 'Europe/London' app.config_from_object('django.conf:settings') app.conf.update(BROKER_URL='redis://:password@host:port', CELERY_RESULT_BACKEND='redis://:password@host:port') In my settings I just have - CELERY_BROKER_URL = 'redis://:password@host:port' If I check heroku redis:credentials REDIS_URL I get - rediss://:password@host:port Is the difference between redis and rediss doing something here? I've also seen on the documentation the usual set up for Redis is - 'redis://:user:password@host:port' - but I haven't had to add a user in before and it has worked fine. There is also no named user when looking at the Redis credentials on Heroku. As I mentioned it was working perfectly fine until a week ago and nothing has changed other than Redis updating as it does periodically. -
Why is the 'r' before strings in python so important?
I am fairly new to the Django framework and for a couple of hours I was getting TemplateNotFound error returned when I tried to map my views.py to my templates directory. This issue was eventually solved just by inputting 'r' before my path to templates in os.path.join(BASE_DIR, 'templates') to become os.path.join(BASE_DIR, r'templates'). I really want to understand better what function it carries out on the string. what is the big idea? -

how to make function call independent to Django server?
I have a python module which updates database infinitely for multiple connections. To start the work I have a button in UI to initiate the call using ajax and django views action is like below views.py def initiate_all(request): pool = Pool(4) pool.map_async(enableUpdate, [entity] for entity in range(3)) return HttpResponse() for three iterations it calls function and establishes three concurrent connections to update the data like below module.py def enableUpdate(e): while connection_is_alive(): connection to db update the values The above code works perfect where its doing multiprocessing to create 3 connection (in above example) and update database respectively. But if django server is stopped it destroys all objects which intern stops database update work as well. Requirement is ones the user clicks start button from UI, python update code should work even if the django server stops running. How to achieve this ? -

How to pass modelform instance fields that are not intended for user input to template in Django
I'm using formsets to pass several modelforms with existing model instances to a template. I'd like to do something in the template for each form depending on the value of a model field (let's call it field_check) for that instance. Field_check is not intended for user input and a required field. If I include field_check into my form without rendering it, I can easily access its value. But then after submitting the form Django complains that field_check is required. What is the recommended way to access the value of field_check without including it as an input field or running into the required field problem? Models.py class MyModel(models.Model): field_check = models.CharField(max_length=50) user_input_field = models.CharField(max_length=50) some_type = models.CharField(max_length=50) Forms.py class MyModelForm(forms.ModelForm): class Meta: model = MyModel fields = [ 'user_input_field', 'field_check', #having this field here creates problems, since it's not intended for user input ] MyFormSet = forms.modelformset_factory(MyModel, form = MyModelForm, extra=0) Views.py def myview(request): this_type = 1 formset = MyFormSet(request.POST or None, queryset = MyModel.objects.filter(some_type = this_type)) if request.method == 'POST': if formset.is_valid(): formset.save() return render(request, 'some_other_template.html') context = {'formset':formset} return render(request, 'mytemplate.html', context) Template <form method="post"> {{ formset.management_form }} {% for form in formset %} {{form.id} # here is the … -
Applying CORS to Django static files
I'm trying to get one project to access resources of another project. I installed django-cors-headers and everything started working fine except for static files.

How to increase request timeout error for larger requests in ngnix

How to authenticate using external endpoint in django
I’m building a webapp with drf which does the authentication by calling an external api. Token received from front end is sent as request parameter. Response contains the Token status (Expired or Active). My app doesn’t have a user model. So all the views should be displayed based on the status of the external api call. To accomplish this, i have added a middleware. If the token status is expired i need to respond with 401 unauthorized json response. I found out drf has HttpResponseForbidden but it returns 403 and http response. which exception or response can i use here? Is it possible to do this in drf authentication classes instead of using middleware? or is there any other way to do this? Below is my middleware code : from rest_framework.exceptions import AuthenticationFailed from django.http import HttpResponseForbidden class AuthMiddleware(object): def __init__(self, get_response): self.get_response = get_response def __call__(self, request): try: # Post call to external api # if Token valid, do nothing # else return Invalid token with 401 code return HttpResponseForbidden("Invalid Token") # currently returns 403 code except Exception as e: print(e) response = self.get_response(request) return response
