Django database error when running tests
I have been trying to solve a database related error for a long time which prevents me from running tests unless I disable migrations temporarily before launching the task. I am getting a ProgrammingError, specifically: django.db.utils.ProgrammingError: relation "django_facebook_open_graph_share" does not exist LINE 1: ...ango_facebook_open_graph_share"."created_at" FROM "django_fa... when running test someapp --verbosity=2.

How to allow access only for kubernetes pods in postgresql?
I have a Django app running in Kubernetes in GKE. And that django app connects to a static (non-containerized) postgresql server. As both of them are located in one zone, my django app uses internal IP to connect to database. I want only my django app to request a connection to the postgresql database and deny connection for requests coming from other IPs. To do that, in pg_hba.conf I did this: host all all 14.133.0.0/24 md5 Because all internal IPs start with 14.133. However, the requests are coming from pod IPs and thus requests for connection are denied. An example for a Pod IP can be 14.4.123.32. So, if I do the following in pg_hba.conf, the problem will be fixed: host all all 14.0.0.0/8 md5 Another thing to note is that Pod IPs always change. So, this solution will break once the pod is updated. What is the best practice to go about this? -
Test asc for arg which is self
Test should give 400 status code, but it ascs for self as argument, but isn't it a mistake? This is test: def test_cab_number_does_not_exist(self): data = {"cab_number": "0"} self.client = self.Client url = reverse('api:orders') response = self.client.post(url, data) response_content = json.loads(response.content) cab_number = response_content['cab_number'] self.assertEqual(response.status_code, 400) This function gives mistake like: TypeError: test_cab_number_does_not_exist() takes exactly 1 argument (0 given) . I don't know how to fix it. -
Celery is constantly starting with supervisor
How to run celery in Supervisor?

Organizing a one-to-one relationships for checksums
Django==1.11.6 I'd like to collect checksums for uploaded files. I have done it via GenericRelation. This is clumsy. Because it is one-to-many relationship whereas a checksum is definitely one-to-one. Could you help me understand whether this can be rewritten as a one-to-one relationship case? @receiver(post_save, sender=ItemFile) @receiver(post_save, sender=Image) def save_file_checksum(sender, instance, **kwargs): """ Save a ckecksum for a file.

Running multiple instances of daphne behind a load balancer: django-channels
I am using django-channels to add HTTP2 & WebSocket support for my application. I could not find a lot of documentation as to how to scale channels. Below is my nginx configuration that load balances multiple instances of daphne running on the same machine but different ports. Is this the correct way to do it? upstream socket { least_conn; server 127.0.0.1:9000; server 127.0.0.1:9001; server 127.0.0.1:9002; server 127.0.0.1:9003; } server { listen 80; server_name 127.0.0.1; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /home/niscp/home-screen; } location /nicons/ { root /home/niscp/home-screen; } location / { include uwsgi_params; uwsgi_pass unix:/home/niscp/home-screen/home-screen.sock; } location /ws/ { proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_pass http://socket; } } Along with that, I am running individual instances of workers to listen to individual channels in the following manner: python manage.py runworker --only-channels=websocket.connect python manage.py runworker --only-channels=websocket.receive python manage.py runworker --only-channels=websocket.disconnect I have got uwsgi to handle all http requests the way django normally handles them. All daphne and workers do is handle WebSocket requests. Is this a viable method to scale django-channels, or is there something I could do better? -
'Authorization: Bearer token' vs 'Authorization: token' (Can't use Bearer header in Oauth2)
I'm using Oauth2. And somehow I can't attach Bearer header. It only work without Bearer Header. (But header Token header works) Is there any advantage of using Bearer?

Replacing image dynamically using jQuery
I'm trying implement a like button that changes color when clicked. I am trying to replace the image dynamically using jQuery. <div class = "col-sm-10" style = "margin-top: 2%"> <input style = "width : 4%; height: 4%" type = "image" id = {{schedule.id}} + "image" class = "likes" data-scheduleid = "{{schedule.id}}" data-user = "{{curruser.person.id}}" src = "{% static 'img/notliked2.png' %}"/> </div> This is image file that gets pressed as a button. Essentially, I am trying to change the image file on click. $(document).ready(function() { $('.likes').click(function(e){ var sched_id; var curruser; sched_id = $(this).attr("data-scheduleid"); curruser_id = $(this).attr("data-user"); $.get('/profiles/like_schedule/', {schedule_id: sched_id, current_user: curruser_id}, function(data){ var first = data.split("/") $('#' + sched_id).html(first[0]); console.log(first[1]) //$('#likes').html("<input style = 'width : 4%; height: 4%' type = 'image' id = {{schedule.id}} class = 'likes' data-scheduleid = '{{schedule.id}}' data-user = '{{curruser.person.id}}' src = {% static 'img/" + first[1] + "' %}/>"); $('.' + sched_id + "image").attr("src", "{% static 'img/" + first[1] + "' %}") e.preventDefault(); }); }); }); This is the jQuery. I logged first[1], and it is correct. It alternates between "notliked2.png" and "liked2.png" when someone likes and unlikes. But for some reason replacing the image source doesn't work. I even tried replacing the entire html, and it … -
Get the IP of the response hit by the requests library and even make it a bit faster in Django Python2.7
I am creating a django application where I have to scrape my profile for displaying purpose. The following is the views.py: url = 'my public profile' header = {'User-Agent': "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) " "Chrome/43.0.2357.134 Safari/537.36"} extract_profile = requests.get(url, headers=header) Here I have a guess that the scraping what I am trying is done through my server IP. I am not getting the idea to how I can make use of my my local IP for scraping the profile instead of my server IP? Also this process is taking a hell lot of time which is not good or my experiment. So I want to know what I need to improve to make it faster? kindly, let me know so I improve. -

Django model manager transaction and signal

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?

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?

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.

Where answers specify to use the ls command, which is not applicable on Windows command prompt. I have tried this multiple times but i just can't open manage.py -
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?
