How can I differentiate between users with lookup
I have two classes Customer and Restaurant that have OneToOneField with the django built in User. When I go to a page I am trying to determine which User it is. What I am doing doesnt work because the User model will always return True for having a restaurant attribute, so it never makes it past the first if statement... models.py class Restaurant(models.Model): restaurant_user = models.OneToOneField(User, on_delete=models.CASCADE) restaurant_name = models.TextField(max_length=50) about = models.CharField(max_length=500) class Customer(models.Model): customer_user = models.OneToOneField(User, on_delete=models.CASCADE) about = models.CharField(max_length=500) views.py def dashboard(request): if User.restaurant: return render(request,'usermanage/dashboard_restaurant.html') elif User.customer is not None: return redirect(request, 'usermanage/dashboard.html') else: return render(request, 'usermanage/dashboard.html') -

Django : Emails never sent

MultiValueDictKeyError when using DropzoneJS with Django
I'm currently making a profile picture feature for a website, I started using DropzoneJS but I'm having an issue submitting the file. The picture will drop into the zone fine, but it appears with an "X" over it, and when I hover over the picture I can see the MultiValueDictKeyError error. Which is the same error I get when I click the submit button without selecting a file. So I assume the issue is that the file isn't being submitted by the button? How do I do that? HTML/JS: <script type='text/javascript'> Dropzone.options.myDropzone = { init : function() { var submitButton = document.querySelector("#submitBtn") myDropzone = this; submitButton.addEventListener("click", function() { myDropzone.processQueue(); }); this.on("addedfile", function() { document.getElementById('submitBtn').style.visibility = "visible"; }); this.on('addedfile', function(){ if (this.files[1]!=null){ this.removeFile(this.files[0]); } }); } }; Dropzone.options.myAwesomeDropzone = { accept: function(file, done) { console.log("uploaded"); }, init: function() { this.on("addedfile", function() { if (this.files[1]!=null){ this.removeFile(this.files[0]); //document.getElementById('submitBtn').style.visibility = "visible"; } }); } }; </script> <!-- Modal --> <div id="picModal" class="modal"> <!-- Modal content --> <div class="modal-content"> <span class="close"></span> <form action="{% url 'profile_test' %}" method='POST' enctype="multipart/form-data" class="dropzone" id="my-dropzone">{% csrf_token %} <button id='submitBtn' type='submit' style='visibility: hidden;'> Submit </button> <input id='submit-all' type='file' name='uploaded_image'/> {{form}} </form> </div> </div> </body> -

How to place and order django objects from 2 models into template table?
I'm trying to place "information" into a table that has rows and columns called "categories" and "stylings". My model and view are shown below. model.py class Headings(models.Model): categories = models.CharField(max_length=20) stylings = models.CharField(max_length=20) class Information(models.Model): headings = models.ForeignKey(Headings) info = models.CharField(max_length=100) views.py class InformationListView(ListView): model = Information def get_context_data(self, **kwargs): context = super(InformationListView, self).get_context_data(**kwargs) context['categories_ordered'] = Headings.objects.order_by('categories') context['stylings_ordered'] = Headings.objects.order_by('stylings') return context So far I've been able to start my template table with <table> <tr> <th>Styles</th> {% for cols in categories_ordered %} <th class="rotate"><div><span>{{ cols.categories }}</span></div> {% endfor %} </th> </tr> {% for row in stylings_ordered %} <tr> <td>{{ row.stylings }}</td> {% for col in categories_ordered %} <td> ... need algorithm that places the correct info in this cell. {{ Information.info }} </td> {% endfor %} </tr> {% endfor %} </table> There could be 6 different categories and 6 different stylings, but maybe only 4 information objects. So the hard part (imo) is placing the information in the correct cell in the table. I've tried different things but nothing that seems to be close. I imagine this is a fairly common problem that is solved all the time. Thanks -

How to pass foreign key to serializer when creating parent at the same time?
Just to preface, I'm a beginner and I realise my conventions may not be exactly standard so I would be grateful if you would correct me for anything I'm doing completely wrong. Currently, my API is called using: http:127.0.0.1:8000/weather/<latitude>,<longitude> I am pulling weather data from some API, but also want to store it in a database at the same time. To represent the weather, I have two models, Location and Currently which hold the coordinates and weather information. In this case, the parent is Location. My issue is I don't know how to pass the Location foreign key to CurrentlySerializer. In the code below I'm not passing it in at all and I receive the obvious "location field is required" error. views.py def get(self, request, *args, **kwargs): # Process latitude and longitude coordinates from URL coordinates = kwargs.pop('location', None).split(",") latitude = coordinates[0] longitude = coordinates[1] # Retrieve weather data. forecast = get_weather(latitude, longitude) currently = forecast['currently'] # Serialize and confirm validity of data. location_serializer = LocationSerializer(data=forecast) if not location_serializer.is_valid(): return Response(location_serializer.errors, status=status.HTTP_400_BAD_REQUEST) currently_serializer = CurrentlySerializer(data=currently) if not currently_serializer.is_valid(): return Response(currently_serializer.errors, status=status.HTTP_400_BAD_REQUEST) response = location_serializer.data + currently_serializer.data return Response(response, status=status.HTTP_200_OK) models.py class Location(models.Model): ... some fields class DataPoint(models.Model): ... some fields … -
djstripe customers not deleted
I have a test website that will be using stripe and djstripe 0.8.0 for subscription payments. I had the test data set up to test the payments system was working. I then deleted the stripe test data. However, when I open the django admin console and navigate to djstripe > customers, I have the following records displayed, but no users/customers attached to them: There are no records in the corresponding database table. I have even deleted the customers from stripe and the database itself. Still cannot get rid of these records. If I try to access the records or delete the records from the admin console, I receive the following error message: AttributeError: 'NoneType' object has no attribute 'email' File "C:\Users\me\desktop\myappname\env3\lib\site-packages\djstripe\settings.py", line 94, in get_subscriber_model_check_subscriber_for_email_address(subscriber_model, "The customer user model must have an email attribute.")

Websocket connection by Apache2 + mod_wsgi + Django

MultiValueField does not work with ModelChoiceField

Passing the widget to ModelChoiceField does not work as it makes a copy if it's an instance. Thus I set the choices attribute manually as you can see in the commented out code. But then I got another error which I didn't resolve: AttributeError: 'RelatedFieldWidgetWrapper' object has no attribute 'decompress' -
short polling versus websockets for short duration requests
So we have a Django backend server that communicates with a large number of 3rd party servers. These 3rd party servers all use socket connections for communication, not HTTP. Each user request to our service will communicate (over a socket) with one of many possible 3rd party servers. Each 3rd party server can take 1-20 seconds to respond, although usually it is around 1-5 seconds. Of course when a user goes to our webpage to make a request for one of those 3rd party services, we want to respond to our user as quickly as possible, ie don't block on our server waiting for a response. When the 3rd party server responds, then we want to push the response back to the user's browser. Certainly this is a common problem. But the key here is that we will be issuing requests to our web server every 5 seconds or so (e.g. using JavaScript/AJAX in our web pages). I understand that if we were able to create a websocket connection for the response and leave it open, and/or if our requests were really long duration (say >30 seconds), then websockets would be a good way to go for server push. However, … -
Class Variables vs Methods in Django Class Based Views
I am a self-taught amateur ever trying to understand fundamentals of Python, Django and programming in general. I'm looking to understand an issue I was having. So I have this class class ContractsView(InventoryView): template_name = "contracts.html" page = "Contracts" primary_table, secondary_table = build_contracts_tables(**{"commodity": None}) and it uses the following function: def build_contracts_tables(**kwargs): print('fire') primary_table_query = Purchase.inventory.current_contracts_totals(**kwargs) primary_table_fields = ("total_meats", "total_value", "meat_cost") primary_table_html = build_table([primary_table_query,], *primary_table_fields) if primary_table_query else err_str secondary_table_query = Purchase.inventory.current_contracts(**kwargs) secondary_table_fields = ("invoice", "supplier", "variety", "meats", "value", "meat_cost", "ship_date") secondary_table_html = build_table(secondary_table_query, *secondary_table_fields) if secondary_table_query else err_str return primary_table_html, secondary_table_html Somehow, the view is sending something to the template, as it does render some data. However, the data doesn't update right away (it eventually does), meaning I will refresh it after changes to the database, but old data will persist. Additionally, I don't ever see my print appear in the console. However, when I convert the class variables into functions, it works just fine: class ContractsView(InventoryView): template_name = "contracts.html" page = "Contracts" def primary_table(self): x,y = build_contracts_tables(**{"commodity": None}) return x def secondary_table(self): x, y = build_contracts_tables(**{"commodity": None}) return y Could someone help me understand the rule I am breaking in my original attempt? -
Django Rest Framework - return list of Users or single User with ModelViewSet based on Permissions
I have seen several posts similar to this question, but none that solve my issue. I am using Django Rest Framework's ModelViewSet. I have two views, a detail view and a list view. I want it so that if a superuser accesses my list view, he gets all the users. If a normal user accesses a list view, he can only see himself. If a superuser accesses the detail view, he can view any user. If a normal user accesses a detail view that is not his, he gets an authentication error. I first attempted this with permissions only, but realized that with a query set of all for the list view the has_object_permission is not run allowing an authenticated non-superuser to view everyone. This is because object permissions are only run with a get command. I attempted to only override get_object, but get_object is not called for the list view so it made no difference. So I tried to override get_quertyset without get_objects, but this broke my detail view. What I understand is that get_object is called first for a detail view, which then calls get_queryset if I don't override either of them. But if I override get_queryset, it … -
Django model foreign key in the same table

Making an instance that puts two instances from different models together

How can I create a django application that can run anaconda code?

I already tried to get an answer here: What is the easiest way to start a Django project within an anaconda environment?
