Django Rest Framework: docs not found
Django 2.0.1 DRF 3.7.7 I am using automatically generated documentation provided by DRF. My urls.py: from rest_framework.documentation import include_docs_urls urlpatterns = [ ... path('docs/', include_docs_urls(title='My API')), ... ] This used to work just fine in the past, but recently it stopped working (I don't know why). When I try to access the docs at http://localhost:8000/docs/, it gives me the DRF 404 error: Error {'detail': 'Not found.'} Additional Information Note: You are seeing this message because DEBUG==True. Seeing this page is usually a configuration error: are your DEFAULT_AUTHENTICATION_CLASSES or DEFAULT_PERMISSION_CLASSES being applied unexpectedly? Your response status code is: 404 401 Unauthorised. Do you have SessionAuthentication enabled? Are you logged in? 403 Forbidden. Do you have sufficient permissions to access this view? Is you schema non-empty? (An empty schema will lead to a permission denied error being raised.) Most commonly the intended solution is to disable authentication and permissions when including the docs urls: url(r'^docs/', include_docs_urls(title='Your API', authentication_classes=[], permission_classes=[])), Overriding this template If you wish access to your docs to be authenticated you may override this template at rest_framework/docs/error.html. The available context is: data the error dict above, request, response and the debug flag. This is very strange. I have no idea … -
How do I put a task on hold/defer in Celery until a condition has been met?
I need help with celery. I'm creating a web service to send vouchers which are in three categories thirty,fifty and hundred. Each of these vouchers are stored in their own models. The payment gateway sends an Instant Payment Notification to my website which I then process and filter the amount and phone number from the JSON. The logic I would like to implement is if the amount == 30, An unused voucher(boolean) is picked from model thirty and sent via an SMS gateway to the phone number from the Payment Notification. The same case for 50 and 100. I would like the SMS sending function be done with celery. Now here is my biggest challenge, if the amount is not equal to any of those three values, the task is put on hold until one of the conditions is satisfied and the sender receives a notification of insufficient amount via the SMS gateway. Can you help with that? -

Check and clear filters with django-filter
I am using django-filter to filter a ListView and would like to display a "Clear all filters" link if any filters are applied. Due to the generic nature of the filtering system I haven't yet found a straightforward way to achieve this. The only thing I came up with so far is to return the regular queryset in the get_queryset method of the view if a "clear" flag is present in the request, however this doesn't actually clear the filters - it just returns all the data. Does anyone have a solution/idea for this? -

is an open cassandra cqlsh cluster/session in python usable for making other queries?
I'm new on apache cassandra. im using a django program that needs to work with cassandra and im using cassandra-driver as it's recommended on documentations. when i use this code it creates a connection session to cassandra named "default". from cassandra.cqlengine import connection connection.setup([settings.CASSANDRA_SERVER], default_keyspace=settings.CASSANDRA_KEYSPACE) i wanted to get sure if it's ok to use this session as long as it's open or not? in my test i wrote a function that checks if session is closed then creates another session. def checkConnection(): try: connection.get_connection("default") except: connection.setup([settings.CASSANDRA_SERVER], default_keyspace=settings.CASSANDRA_KEYSPACE) i use this functoin before making cqlengine queries. is it rational for production or not? -

Optimal way to chain reverse foreign key lookups in Django
We have a DB model that looks something like this, where each arrow represents a many to one relationship in the direction of the arrow: A --> B --> C --> D < -- E For most models, we have a property called D. For C, that method returns D. For B, that method calls C.D() and so on. These we can use for FK lookup. The problem arises for reverse lookups, since these chained properties are unavailable when generating SQL statements, meaning we would have to load the entire QuerySet into memory to filter on those properties. Ideally, we could do something like A.objects.filter(D=someD). What we instead do is lookup based on relations and chain a bunch of joins. The syntax is nice for one join, but it quickly becomes hard to maintain. If we want to get all A objects related (indirectly) to D, we have to doA.objects.filter(B__C__D=someD). Having to write code like this in multiple places is obviously not ideal. We have looked into F annotations and a custom manager for each model without much luck. TLDR: What's the optimal way to chain reverse lookups? Thanks in advance! -
How to reassign object id's in Django?
I am developing a Polling application in which i had created bunch of questions and their respective options , one has to choose and vote for the question. In the process i had deleted few questions in between , now the ID's of the questions are missing in between.

Django Form Does Not Find Right ID int Increment on Production vs LH
For some reason on Localhost (LH) everything works fine but on my Production server, my form does not add a new user submission properly. The error I am getting is: duplicate key value violates unique constraint "..." DETAIL: Key (id)=(8) already exists. Is there some sort of production "sudo systemctl restart gunicorn" I need to run (I have already tried the example above)? Maybe it's only working on LH because there I have tested there more and the increment naturally fell on the same level as the total amount of users? I really am out of ideas here. models.py class Lead(models.Model): username = models.CharField(max_length=15, blank=True, null=True) email = models.CharField(unique=True, max_length=150, validators=[validate_email]) created = models.DateTimeField(auto_now_add=True) ... forms.py class LeadCaptureForm1(forms.ModelForm): birth_date = forms.DateField(widget=SelectDateWidget(years=range(1999, 1910, -1))) class Meta: model = Lead widgets = { 'email': forms.TextInput(attrs={'class': 'form-control'}), } fields = ('email', 'birth_date',) views.py def iframe1(request): ip = get_real_ip(request) created = timezone.now() if request.method == 'POST': form = LeadCaptureForm1(request.POST) if form.is_valid(): # Save lead lead = form.save() lead.id = Lead.objects.get(all).count() print(lead.id) lead.created = created lead.birth_date = form.cleaned_data.get('birth_date') lead.ipaddress = get_real_ip(request) lead.joinmethod = "Iframe1" lead.save() print(lead) -
Django - Populating data from database in a dropdown select tag
I've been trying to create an edit option in the frontend for the users to be able to change different settings. At the moment I am bit stuck with the dropdown showing the options that are already saved in the database. I don't know what I'm missing, I hope you can help me out. -- This is what I have in my models.py STATUS_CHOICES = ( ('4', 'Interview'), ('5', 'Rejected'), ('2', 'Following'), ) class StatusType(models.Model): status = models.CharField(max_length=90, choices=STATUS_CHOICES) def __str__(self): return self.status class JobStatus(models.Model): job_application = models.ForeignKey(JobApplication, on_delete=models.CASCADE) def __str__(self): return self.status_type.status -- This is what I have in my index.html {% with object.jobstatus_set.all|first as status %} <form action='' method="post"> <select class="dropdown" type="dropdown" name='job_status'> <option value={{ status }}> {{status}} </option> </select> </form> {% endwith %} Right now it works if I login into the database and assign the value for the job, otherwise the dropdown menu is empty. What I want is to be able to see all the options when clicking on the select menu, so that the users set it to their own choice and then save it. Thank you, any help is very much appreciated. -

Ajax call time to load in django application

Passing CSRF Token/Authenticating a POST request to Django-Rest-Framework from a React Form
I'm trying to post data from a form built in React over a Django-Rest-Framework API and have run into an issue with the authentication. I can post fine if I turn off authentication on the API View, so I think I've narrowed it down to how I'm passing the data in the form. My DRF view looks like this: class PropertyListCreate(generics.ListCreateAPIView): authentication_classes = (SessionAuthentication,) permission_classes = (IsAuthenticated,) queryset = models.Property.objects.all() serializer_class = serializers.PropertySerializer The handler for the Submit is below. handleSubmit = e => { e.preventDefault(); const { name, type, address, city, state, zip_code } = this.state; const property = { name, type, address, city, state, zip_code }; const conf = { credentials: 'include', method: 'POST', body: JSON.stringify(property), headers: { 'Accept': 'application/json', 'Content-Type': 'application/json', 'X-CSRFToken': cookie.load('csrftoken') } }; fetch(this.props.endpoint, conf).then(response => console.log(response), console.log(conf) ); }; When I attempt to post with the above code, I get a 400 Error - and if I remove the 'X-CSRFToken': cookie.load('csrftoken'), I get a 403 Error (Forbidden). My understanding of a 400 Error is that the request was badly formatted, so I'm thinking that I'm sending the csrf token incorrectly? This is the output from console.log(response): Response {type: "basic", url: "http://127.0.0.1:8000/api/properties/", redirected: false, status: … -

I use django 1.11 and this is my wsgi.py file # -*- coding: utf-8 -*- import os import sys from django.core.wsgi import get_wsgi_application PATH = os.path.abspath( os.path.join(os.path.dirname(os.path.abspath(__file__)))) if PATH not in sys.path: sys.path.append(PATH) os.environ['DJANGO_SETTINGS_MODULE'] = 'cms.settings.qa' ENV_VARIABLES_TO_PASS = ['VAR_1', 'VAR_2'] _application = get_wsgi_application() def application(environ, start_response): # pass the WSGI environment variables on thzrough to os.environ for var in ENV_VARIABLES_TO_PASS: os.environ[var] = environ.get(var, '1') return _application(environ, start_response) and when i try to get the env on settings file its allways return None. os.getenv('VAR_1') = None & os.getenv('VAR_2') = None why is that happend? thanks a lot.
