Changed JWT to OAuth2 and getting "Invalid token header. No credentials provided."
I decided to change my HTTP Authorization method from JWT to OAuth2. While testing my API with Postman, I'm getting same error for hours, "Invalid token header. No credentials provided." My header is Authorization: Bearer 416a444281fdcd6d2a344970eea0d47c22d01528 I don't see anything wrong in settings.py, but Do you see any? I commented out JWT setting just in case.

Django QuerySet/Manager filter employees by age from birthday
I am a beginner. I would like to get list employees have age > 25 and calculate the average age of employees. Currently, we need to get age from birthday (I have no idea about it ^^) .

Django model manager transaction and signal
# The model class UserManager(models.Manager): def create_user(self, temp_user_id): new_user = self.create(require data) # insert row to model B # The model manager class User(models.Model): # model fields objects = UserManager() # Post save signal handler def send_notification_to_user(sender, instance, created, **kwargs): # send sms notification to the newly created user signals.post_save.connect(send_notification_to_user, sender=User) # The view class UserView(APIView): def post(self, request, format=None): try: with transaction.atomic(): c_user = User.objects.create_user(request.data["temp_reg_id"]) return Response(status=status.HTTP_201_CREATED) except Exception as e: return Response(status=status.HTTP_400_BAD_REQUEST) In this scenario if a user registered then user get a sms. But here I'm running the model manager in transaction, so if somehow # insert row to model B instruction fails then all database will rollback. The problem is in this situation user will get the account creation sms, which is not true. How can I overcome this problem or which approach will be better? My English is not good, you can ask me for more explanation. -

Django/AngularJS: How do I access my Python Context Items from my AngularJS Script
Good day SO! I am a beginner thats trying out a Django Project while using AngularJS for my frontend Firebase chat system. Here is a previous question that I asked regarding this project: Firebase/Angular: Messages not showing in HTML, but contain the message objects I know that it is not wise to use json variables on your html directly while using django/python, but it just so happens that my firebase chat module is using angularJS (and I do not know how to code this chat function in django..), and my angularJS code requires access to my Django's context querysets from View.py. Is there any way that I can either: Push json items into my HTML/Template the same way I push context information into my HTML/Template from Views.py and use it in my AngularJS Script? Access my Django/Python's data sets from Context from Views.py? Here is my AngularJS code for firebase: var app = angular.module('chatApp', ['firebase']); app.controller('ChatController', function($scope, $firebaseArray) { //I want to populate the crisis and sender variables with something from my context //from Views.py.. var crisis = "Crisis1"; var sender = "Sender1"; //Query var ref = firebase.database().ref().child(crisis).child('CMO-PMO'); $scope.messages = $firebaseArray(ref); $scope.send = function() { $scope.messages.$add({ sender: sender, message: $scope.messageText, … -

AttributeError at /notify/notify/ 'UserNotifications' object has no attribute 'user'
I am trying to make a notifications app. I have a middle that collects info about the action the user should be notified about and in the view that handles the action it automatically creates an instance in the UserNotification model. This is all working. Now, if a user's post gets liked by another user, that actions needs to be displayed on the notifications page. However, I obviously don't want any one use to be able to see every notification that is being created on the site, but rather only the notifications that are created by their posts. I am running into an issue with the view and filtering the notifications based on the current user. More specifically, I am getting this error: AttributeError at /notify/notify/ 'UserNotifications' object has no attribute 'user' With traceback: Traceback (most recent call last): File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/core/handlers/exception.py", line 41, in inner response = get_response(request) File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/core/handlers/base.py", line 187, in _get_response response = self.process_exception_by_middleware(e, request) File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/core/handlers/base.py", line 185, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/views/generic/base.py", line 68, in view return self.dispatch(request, *args, **kwargs) File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/contrib/auth/mixins.py", line 56, in dispatch return super(LoginRequiredMixin, self).dispatch(request, *args, **kwargs) File "/anaconda3/envs/dev/lib/python3.6/site-packages/django/views/generic/base.py", line 88, in dispatch return handler(request, *args, **kwargs) … -

I can't open manage.py
On the command prompt, (Windows 10) I created a virtual environment, I then created a new project, I installed django in the virtual environment using pip. Then decided to run the command python manage.py runserver To run djangos web server, This returned with "...can't open file 'manage.py': [Errno 2] No such file or directory" I did see a similar question to this on this platform but it seems to only apply to those using linux.

Django creates migration files after each 'makemigrations' because of dictionary?
I've noticed strange things in my Django project. Each time I run python manage.py makemigrations command new migration file for my app called notifications is created. I did zero changes to the model, but the new migration file is created. I can run makemigrations command N number of times and N number of migration files will be created. The model looks as following: from django.db import models from django.db.models.fields import EmailField class EmailLog(models.Model): email = models.EmailField(max_length=70, null=False) subject = models.CharField(max_length=255, null=False) html_body = models.TextField(null=False) sent_choices = { ('OK', 'Sent'), ('KO', 'Not sent'), ('KK', 'Unexpected problems') } status = models.CharField(max_length=2, choices=sent_choices, null=False, default='KO') sent_log = models.TextField(null=True) sent_date = models.DateTimeField(auto_now_add=True, null=False) Each migration just swaps the position of sent_choices field. that's all! Is it because dictionaries in Python have random order? How do I avoid it? -

django + gunicorn + nginx: Browser refreshes toggling between PRE/POST dynamic content change
Below are the nginx.conf and gunicorn.start.sh files that I use for the Django application that I'm running (which, by the way, I didn't write). When I make any one-time change to dynamic content, then repeatedly refresh the browser, the rendered content switches/flaps variously between PRE and POST changes made. But it should just update once, and never again. The only thing that momentarily fixes the issue is restarting gunicorn: myapp$ sudo supervisorctl restart gunicorn But this only works until the next change to dynamic content. No good. I've tried numerous browsers, and it happens even when I clear their caches. Makes no difference. I also temporarily tried uWSGI instead of gunicorn (just to see), and the same issue occurs. A tail -f gunicorn.access.log during browser refreshes shows HTTP statuses that vary between 200 (content was downloaded) and 304 (you already have the content; redirecting you to your local cache). But dynamic content shouldn't be cached. Note that when running the application using the development server, like this: myapp$ python manage.py runserver --settings live 0.0.0.0:8080 the issue doesn't occur; but neither does this use nginx nor gunicorn. Any ideas? I've tried everything I know, but don't know what is causing this … -

Unresponsive django-bootstrap3-datetimepicker (not showing calendar)
As a beginner I often struggle with understanding the connections between Python-Django, html, javascript and css. The problem at hand is this: I'm trying to implement DateTimePicker widget from django-bootstrap3-datetimepicker-2. Since this library does not include js/css assets, I started by implementing datetimepicker without backend involvement just to see if I loaded all static files etc. correctly. Thus, I added this example to html template: <div class="container"> <div class="row"> <div class="col-sm-6"> <div class="form-group"> <div class="input-group date" id="datetimepicker1"> <input type="text" class="form-control"> <span class="input-group-addon"> <span class="glyphicon glyphicon-calendar"></span> </span> </div> </div> </div> <script type="text/javascript"> $(function () { $('#datetimepicker1').datetimepicker(); }); </script> </div> </div> Everything worked as intended, so I tried to implement datetimepicker as a widget from django forms: class FooForm(forms.Form): pick_a_date = forms.DateTimeField( widget=DateTimePicker(options={ "format": "YYYY-MM-DD", "pickTime": False} )) I also wanted to benefit from form wizard (namely SessionWizardView from formtools.wizard), so I output the above mentioned form into html like this: <form action="" method="post" role="form">{% csrf_token %} <table> {{ wizard.management_form }} {% if wizard.form.forms %} {{ wizard.form.management_form }} {% for form in wizard.form.forms %} {{ form }} {% endfor %} {% else %} {{ wizard.form }} {% endif %} </table> However, the widget is not responsive (the calendar window isn't showing, the … -

Creating / storing a form preview with Django forms and cart
I've never had to do this before and I'm wondering if I'm on the right track / this is the standard way to do something of this nature. I was going to use Django formtools FormPreview but it doesn' handle files (They can upload various images)... So, rolling my own solution or trying to. Currently I'm using a form wizard with model forms and everything validates / saves fine. I now want to add in a form preview, before purchasing the item they create with the form, and I've thought about doing the following: Save it to the database but mark it as not paid / inactive. On the form preview page grab the id (from pk in url) and display it. They have the option to go back and edit (update view) and / or pay. Using this route it's really easy to update and grab the data for viewing whether they wish to go back or forward. Similarly, if they add multiple items in their cart I can just display these items by grabbing the pk's from the DB rather than trying to handle a ton of session data. If they remove the item -> delete the row … -
Django UpdateView - get initial data from many-to-many field and add them when saving form
I'm using Django class based generic view. In my models.py I have a model called MyModel with many-to-many field called m2m. I have multiple groups of users they can edit the m2m field. Each group of users can only see and add their portion to the field - using get_form to set what they can see in the m2m field. The problem I'm having is that when one user enter his record it will delete the initial records in the m2m field. I need to somehow get the initial values from the m2m field save them and then add them to the new ones when the form is submitted. Here is my views.py: class MyModelUpdate(UpdateView): model = MyModel fields = ['m2m'] def get_initial(self): return initials def get_form(self, form_class=None): form = super(MyModelUpdate, self).get_form(form_class) form.fields["m2m"].queryset = DiffModel.objects.filter(user = self.request.user) return form def form_valid(self, form): form.instance.m2m.add( ??? add the initial values) return super(MyModelUpdate, self).form_valid(form) def get_success_url(self): ... -

How to start building a django website with postgres nginx and gunicorn on separate machines?
I searched all over the internet and I guess I'm lost, Please I want a detailed answer here. I know how to make all three of these things(gunicorn, Nginx, and Postgres) work on the same machine but what if I wanna have all of them on the different/individual machine. Let's say I got 3 behemoth powerful machines capable of handling anything but the real question in my mind is where do I start. how can I connect all three of these together? what if I wanna add more storage? How do I connect multiple database machines together I'm sorry but I'm pretty new in networking and it's really crucial for me to understand this because if I don't my mind won't allow me to go ahead with the process.
