the JSON object must be str, not 'bytes'-django for user validation
I have three different fileds username,password and role if all these three values matches then user will be able to login else he will not be able to login. def loginemployee(request): body_unicode = request.body.decode('utf-8') body = json.loads(body_unicode) payload = body['username'] passwordcheck = body['password'] rolecheck = body['role'] if payload: employee=models.Employees.objects.filter(Q(username=payload['username']) & Q(password=passwordcheck['password']) & (Q(role=rolecheck['role']) | Q(backup_role=payload['role']))) # employees1=models.Employees.objects.filter(Q(email=payload['username']) & Q(role=payload['role'])) # empl=(employee+employees1); if employee: emp = serializers.serialize('json', employee) return HttpResponse(emp,content_type='application/json') can you help me the fix the issue in the above code. -
Pyhton/Django: I need some code to run between requests, which concept to look for?
I am trying Django for my project, which contains server-side code, which should work between requests. It should be initialized at server start, keep state, and polled sometimes between HTTP requests. I can write own server with python http.server but it seems overkill at the moment, simple (Django built-in HTTP) server is ok for my project for now. Which is simplest way to implement server-side code for typical Django project? -
Nginx whitelist API requests from server as client, block all others
I have a Django application with a couple of API endpoints using Django Rest Framework that I want to only be accessible by the Django application itself. I'm trying to restrict access those endpoints via nginx but everything I've tried either results in a 403 fobidden response on all clients or is able to be accessed by all clients. Below is my nginx config. I've also tried replacing 127.0.0.1 with the IP of the server but that results in the same responses mentioned above. upstream app_server { server 127.0.0.1:9000 fail_timeout=0; } upstream api_server { server 127.0.0.1:9001 fail_timeout=0; } server { listen 80 default_server; listen [::]:80 default_server ipv6only=on; root /usr/share/nginx/html; index index.html index.htm; client_max_body_size 4G; server_name _; keepalive_timeout 5; location /endpoint1/ { allow 127.0.0.1; deny all; } location /endpoint2/ { allow 127.0.0.1; deny all; } location /static/ { autoindex on; alias /path/to/static/; } location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://app_server; } } TL;DR I have a Django API that should only accept requests from the Django app running alongside it. What is the best way to accomplish that? -
Safari recognises JavaScript files as "text/plain"
I'm using Mezzanine 4.2.3 running on Django 1.10.8. JavaScript files load fine on Chrome, Firefox, Opera, and Edge. But Safari doesn't recognise them. In Network in Web Inspector, every JS file is recognised as "text/plain". Based on various solutions I've read, I've added type="text/javascript", and then type="application/javascript", like so: {% compress js %} <script type="application/javascript" src="{% static "mezzanine/js/"|add:settings.JQUERY_FILENAME %}"></script> <script type="application/javascript" src="{% static "js/bootstrap.js" %}"></script> <script type="application/javascript" src="{% static "js/bootstrap-extras.js" %}"></script> ... {% endcompress %} I have this at the top of the template too: <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8"> ... </head> Neither works. Console shows no errors. CSS files are recognised as "text/plain" too, but they actually load perfectly. What else should I try? -
With Django AnyMail with MailGun, does the MAILGUN_SENDER_DOMAIN have to match the domain in the DEFAULT_FROM_EMAIL?
Consider the following settings.py snippet from https://github.com/anymail/django-anymail: INSTALLED_APPS = [ # ... "anymail", # ... ] ANYMAIL = { # (exact settings here depend on your ESP...) "MAILGUN_API_KEY": "<your Mailgun key>", "MAILGUN_SENDER_DOMAIN": 'mg.example.com', # your Mailgun domain, if needed } EMAIL_BACKEND = "anymail.backends.mailgun.EmailBackend" # or sendgrid.EmailBackend, or... DEFAULT_FROM_EMAIL = "you@example.com" # if you don't already have this in settings In this example, both the MAILGUN_SENDER_DOMAIN and DEFAULT_FROM_EMAIL have the domain example.com. We've recently made a change such that the two domains are different, and it seems that I am no longer able to send emails using the AnyMail backend. My theory is that MailGun 'enforces' the two domains to be the same, but it is not clear to me from the documentation whether this is indeed the case. Can anyone confirm whether this is required? -
Django how to read a file in the app subdirectories folder?
I am using Django to build a Web application, and there is python module inside the app folder. This python module needs to interact with yaml in the subdirectories "input" and "output". map_local_path = "./input/map.yaml" I just tried to read this path, it will work at my local spyder ide, but it wont work when it comes to Django. I want to call my own python module api in views.py, and what I am doing is to: openFile = open("./input/map.yaml", "r") and I cannot make it work at Django. How can I fix it? T_T Thanks! IOError: [Errno 2] No such file or directory: './input/map.yaml' -
difference between Django Spatial Field Types
I am going to use one of Spatial fields in my project but I don't know the difference between all of them, the Django documentation has two example(PolygonField and RasterField) model: from django.contrib.gis.db import models class Zipcode(models.Model): code = models.CharField(max_length=5) poly = models.PolygonField() class Elevation(models.Model): name = models.CharField(max_length=100) rast = models.RasterField() database api example: >>> from zipcode.models import Zipcode >>> z = Zipcode(code=77096, poly='POLYGON(( 10 10, 10 20, 20 20, 20 15, 10 10))') >>> z.save() >>> from elevation.models import Elevation >>> dem = Elevation(name='Volcano', rast='/path/to/raster/volcano.tif') >>> dem.save() I wanna example code for other fields to understand them : GeometryField PointField LineStringField MultiPointField MultiLineStringField MultiPolygonField GeometryCollectionField -
Edit django 'through' model inline in wagtail admin?
As per the title I am trying to allow for inline editing for a very simple shop page in Wagtail (will probably make it into a simple package): With the following models: class Order(ClusterableModel): fields... class Product(ClusterableModel): fields... class OrderProducts(Orderable): product = ParentalKey(Product, related_name='chosen_products') order = models.ForeignKey('Order') quantity = models.PositiveIntegerField() panels = [ Fieldpanels... ] class OrderModelAdmin(ModelAdmin): model = Order menu_label = 'Orders' ... modeladmin_register(OrderModelAdmin) The tricky thing is that I get the error Cannot set values on a ManyToManyField which specifies an intermediary model. Or I simply don't get an inline panel, but rather a select. I am assuming this is the case because the create and add methods do not work on through models, is that the case? If so could you suggest a way I can rewrite the app so as to allow me to create orders with products in the admin and in my code? -
How can I read a URL without using urlib2.urlopen in Python?
I've been reading and displaying a Facebook Graph api url form the Facebook Graph API like this: facebook_info = urllib2.urlopen("https://graph.facebook.com/%s/me?fields=first_name,last_name,email&access_token=" % settings.FACEBOOK_API_VERSION + access_token) facebook_info = facebook_info.read() return facebook_info I was wondering if there is a better way to do this in Python I was thinking something like Request.get(...). Where I don't use urllib2.urlopen and the the '+' sign to concatenate. -
Using the URLconf defined in tango_with_django_project.urls, Django tried these URL patterns, in this order:
I've been going through the Tango With Django 1.7 guide and I've come up with the following issue that I'm having troubles fixing: Using the URLconf defined in tango_with_django_project.urls, Django tried these URL patterns, in this order: 1. ^$ [name='index'] 2. ^about/$ [name='about'] 3. ^category/(?P<category_name_slug>[\w\-]+)/$ [name='category'] 4. ^admin/ 5. ^rango/$ 6. ^about/ 7. ^category/ 8. ^media/(?P<path>.*) The current URL, rango/category/python, didn't match any of these.

Django graphene relay restricting queries to objects owned the user
I am doing the graphene tutorial on filtering with relay from: http://docs.graphene-python.org/projects/django/en/latest/filtering/ where the user is restricted to query objects that they previously created. class AnimalFilter(django_filters.FilterSet): # Do case-insensitive lookups on 'name' name = django_filters.CharFilter(lookup_expr=['iexact']) #changed this to work class Meta: model = Animal fields = ['name', 'genus', 'is_domesticated'] @property def qs(self): # The query context can be found in self.request. return super(AnimalFilter, self).qs.filter(owner=self.request.user) I am having an inserting the self.request.user part, where the user data is loaded. When I do a query like: query { allAnimalss { edges { node { id, name } } } } I get an error in the query field: { "errors": [ { "message": "'NoneType' object has no attribute 'user'", "locations": [ { "line": 2, "column": 3 } ] } ], "data": { "allAnimals": null } } If I remove the filter it works fine. The tutorial mentioned "owned by the authenticated user (set in context.user)." what does this mean? I tried adding a get_context_data function to the views.py def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['user'] = self.request.user return context and also changing self.request.user to self.context.user but it does not work -

How to get Task ID in celery django from the currently running Shared Task itself?

Extending a Django model with custom field and save logic
I'm using an open source Django app that logs all requests to a model. It stores things like path, ip, user, queryset, etc. However, I'm interested in see which paths take the longest, so I can optimize them, yet the app doesn't store the explicit start and end time it takes to process the request, so I want to extend this model to seamlessly support this without adding any new models. The maintainer of the Django app doesn't want to add this functionality, and I don't want to fork it, extend it, and maintain a completely separate app. So I've decided to implement just these new features by dynamically adding a couple fields using Django's class_prepared signal, and a custom save process to update these field values using Django's post_save signal. My code looks like: from django.db.models.signals import class_prepared, post_save def add_request_fields(sender, **kwargs): """ class_prepared signal handler that checks for the model named MyModel as the sender, and adds a CharField to it. """ if sender.__name__ == 'Request': # Create a field to record when we first receive the request. field = DateTimeField(_('start time'), default=None, db_index=True, blank=True, null=True, editable=False) field.contribute_to_class(sender, 'start_time') # Create a field to record to total seconds … -
