Show list of related objects in Django
I have an issue with displaying list of related articles in my Q&A DetailView. I have a field where user can connect an article to Q&A from admin site.

Saving dropdown menu selection as a cookie in Django
I'd like to save a user selection from a dropdown menu as a cookie. I've seen this question asked before but never fully in python. I wish to use these two cookies in running a simple piece of code so there is no need for a database to be used. Here is my current HTML code: <form role="form" method="post"> {% csrf_token %} <div class="form-group"> <label for="dog-names">Choose a dog name:</label> <select name="dog-names" id="dog-names" onchange="getSelectValue"> <option value="rigatoni">Rigatoni</option> <option value="dave">Dave</option> <option value="pumpernickel">Pumpernickel</option> <option value="reeses">Reeses</option> <option value="{{ current_name }}"> {{ current_name }}</option> </select> <br/> <label>Current dog: {{ current_name }}</label> </div> <button type="submit" value="Submit" class="btn btn-info">Submit</button> </form> Python def cookies_test(request): template_name = 'cookies.html' current_name = "Rigatoni" # default name if request.method == 'GET': if 'name' in request.COOKIES: current_name = request.COOKIES['name'] elif request.method == 'POST': current_name = request.POST.get('name') response = render(request, 'test.html', { "current_name": current_name }) response.set_cookie('name', current_name) return response The python works if I give a value to {{ current_name }} All I want is to be able to save a value from a dropdown menu in a variable so I can save it as a cookie Any advice at all would be appreciated :) -
Is there a more faster and efficient ways to send email in django so that the user does not have to wait the entire time the page loads
I am making a website where a user registers to book an instructor for a certain period of time according to a plan he chooses. There are three plans from which a user can choose namely 7days, 14days and 21days. After registering, the user needs to accept an agreement and then based on the plan he has chooses an expiration date is set from the day the user has accepted the agreement. Now after the user, has accepted the agreement, a copy of the agreement is sent to the user as well as the owners of the website through email. The owners want this system, where the copy of agreement is recieved by both the user and them. I am able to make this happen, and the site is working fine in the testing phase. So basically, two emails are sent after the user accepts and a Contract model is updated. Now, I have noticed that sending two emails takes a good of time, and the page keeps on loading until both the emails are sent, and then the redirects and all happens for the user. This waiting time may trigger some users to press back interrupting the smtp connection, … -

Using pymongo but still getting improperly configured database error
Having read through a lot of posts on the following error, I have understood that if you connect to your MongoDB database via pymongo, you should remove the DATABASES section in your settings.py file: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details. I have removed it, but I still get this error. Nonetheless, I have tried the suggestions in related posts, to no avail... In my settings.py file, I have my database connection: DB_NAME = 'mongodb+srv://User2021:TestMe@cluster0.j9jz1.mongodb.net/test' In my views.py file, I have written a simple method, just to start off: @csrf_exempt def consumers(request): data = ConsumerModel.objects.all() if request.method == 'GET': print("consumers") serializer = ConsumerModelSerializer(data, many=True) return JsonResponse(serializer.data, safe=False) When I enter the http://localhost:8000/consumers/, I just wanna see that the python print statement writes consumers.

Django admin missing models in one enviroment but not in other?
We have a weird problem with our development right now. Two of us are developing a softare using django. In my enviroment, I have full admin page with all the models and management options we have added. On our deployed test server, both me and him have the same options. However, on his own local server, running the exact same codebase that I do, these options are missing and he can only see handful of options. Any idea what might be causing this? It is making testing difficult. -

Django forms passed instance object gets overridden in is_valid
I was working on a Django view that updates the a certain model object x. In POST method, I initiate a ModelForm and pass an instance of the model object x. But when I try to use x object inside if form.is_valid(): block, some values in vars(x) go None. Here's the snippet to explain the scenario. class MyUpdateView(generic.View): form_class = MyModelForm def post(self, request, *args, **kwargs): model_obj = MyModel.objects.get(id=kwargs.get("pk")) # Example: {"emp": 113, "project": 22, "salary": 28000} form = self.form_class(request.POST, instance=model_obj) print(vars(model_obj)) # works fine, shows all the data if form.is_valid(): print(vars(model_obj)) # few values go None, not reusable # Example: {"emp": None, "project": None, "salary": 28000} As we can see, when the vars checked inside the form.is_valid(), something happens to the passed instance object. What could be possibly reason behind this? -

Django Rest Framework: validate HiddenField CurrentUserDefault property
