Run a cron job to check the due date of a task
I'm working in an integration between Django and Chatfuel. Right now the bot is almost complete, I have difficulties with the last task, I have certain tasks to do and each them have a due time, so three days before it expires I have to send a message to my client remindering him/her that he/she have to complete this task. I'm available to obtain the messenger_user_id after the first interaction with my bot, now, I know i have to run a cron job at a frequent interval to check the due date and if it's close, send a message through Broadcasting API. But I don't know how to achieve that goal. models.py class Tasks(models.Model): task = models.CharField(max_length=100) objective = models.TextField() created_date = models.DateTimeField( default=timezone.now) due_date = models.DateTimeField( default=timezone.now) def __str__(self): return self.task views.py #in here I obtain user's fb id def save_fb_id(request, username, fb_id): profile = Profile.objects.get(user__username=username) if profile.fb_id != fb_id: profile.fb_id = fb_id profile.save() return HttpResponse() -
errors while running python scripts triggered by django app
I am building a fully open source testrunner for my needs but I am running into some problems. the test runner parses a yaml file for a set of scripts in various paths and executed the scripts and uses a lib that i will be creating to return the outcome. right now i have a simple ping script that im working to get running and testing as i progress but i am getting a lot of errors. the errors are below and all the source code is also shown below the errors. The github repo for this is here. feel free to pull it in and test the issues i am seeing. https://github.com/castaway2000/testrunner The issue: I am trying to use the testrunner i built to parse a yaml file for paths to scripts i am writing for projects im using. For example if want to use a group of certain tests on a target, i can make a yaml file for each set of the types of tests. There is a certain problem I am seeing with this however, the relative path and exact path of the files are not able to use the django libraries, cause its unable to … -

Specifying basic authentication credentials for a Django REST framework API client

I got a solution working using the APIClient's .force_authenticate method, but I'd prefer to construct the credentials more explicitly. I've tried the following: import json import base64 from django.contrib.auth.models import User from django.test import TestCase from rest_framework.test import APITestCase, force_authenticate from snippets.models import Snippet class SnippetTestCase(APITestCase): def setUp(self): self.username = 'john_doe' self.password = 'foobar' self.user = User.objects.create(username=self.username, password=self.password) # self.client.force_authenticate(user=self.user) credentials = base64.b64encode(f'{self.username}:{self.password}'.encode('utf-8')) self.client.credentials(HTTP_AUTHORIZATION='Basic {}'.format(credentials)) def test_1(self): response = self.client.post('/snippets/', {'code': 'Foo Bar'}, format='json') self.assertEqual(response.status_code, 201) This test passed with the commented-out line with .force_authenticate, but fails in its current form, which I based on Using Basic HTTP access authentication in Django testing framework: Kurts-MacBook-Pro:rest-framework-tutorial kurtpeek$ python manage.py test Creating test database for alias 'default'...

How to handle legacy php-generated passwords in Django
I'm moving a server from php(5.6.32) to Django(1.11.7) that contains thousands of users with passwords encrypted using the password_hash(<pwd>, PASSWORD_DEFAULT) function. Does Django have support for this encryption? It appears neither theBCryptPasswordHasher or the BCryptSHA256PasswordHasher handle this. I believe a custom hasher may be required, but its not clear how to handle this. -

Adding tests to the Django REST framework tutorial
I'm trying to replace an existing function-based view using the login_required decorator with a Django REST framework API using a ModelViewSet. However, it seems like the authentication works a bit differently. In order to try to adapt my unit tests to the Django REST framework case, I cloned https://github.com/encode/rest-framework-tutorial and added a tests.py at the top level directory: import json from django.contrib.auth.models import User from django.test import TestCase, Client from snippets.models import Snippet class SnippetTestCase(TestCase): def setUp(self): self.username = 'john_doe' self.password = 'foobar' self.user = User.objects.create(username=self.username, password=self.password) self.client = Client() self.snippet = Snippet.objects.create(owner=self.user, code="Foo Bar") def test_1(self): self.client.login(username=self.username, password=self.password) response = self.client.post( path='http://localhost:8000/snippets/1/', data=json.dumps({'code': 'New code'}), content_type="application/json") self.assertEqual(response.status_code, 201) However, this returns a 403 Forbidden response: Kurts-MacBook-Pro:rest-framework-tutorial kurtpeek$ python manage.py test Creating test database for alias 'default'...

I then created a couple of users via the admin panel also. I would like my relationships to be: Film can have many comments / Comments belong to film User can have many comments / Comments belong to user I think, like with comments and films, I just need to define user as a foreign key to comment. I am struggling to do this. I am working through the Django tutorials but I can't see the tutorials covering how I can link other tables to the user. I thought I would be able to do something like this: user = models.ForeignKey(User, on_delete=models.CASCADE) While importing User like this: from django.contrib.auth.models import User The result at the moment is if I keep user = models.ForeignKey(User, on_delete=models.CASCADE) I get err_connection_refused -

Pass JSON data in Django context
Normally, if I want to return JSON data from a Django view, I can use a JsonResponse like so: from django.http import JsonResponse def my_view(request): return JsonResponse({'my_key': 'my_value'}) That data is sent to the frontend as a JavaScript object that I can immediately use. I'd like that same ease of use added to the context of a view, like so: class WebsiteView(TemplateView): template_name = 'index.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['my_var'] = {'my_key': 'my_value'} return context However, rendering the template with {{ my_var }} gives: {&quot;my_key&quot;: &quot;my_value&quot;} Ultimately, what I want is for {{ my_var }} to return the plain string rather than the HTML encoded version: {"my_key": "my_value"} This way, I can easily load it into a JavaScript object with JSON.parse('{{ my_var }}'). I know that one way to achieve this is by manually unescaping the HTML entities, but I was wondering if there was a better way to do this. -
Setting up Ubuntu Server 16.04 with Apache to run Django
I have Ubuntu Server 16.04 running Achape. I am trying to get Apache to run Django. So far I have created a project in Django and can get it to run on port 80 by using the command "sudo python3 manage.py runserver 192.168.1.230:80". I would like to have Apache setup to run Django so I do not have to do this command. I have looked for 6 hours now and tried 10+ different ways to do this and can't get it to work. I usually end up getting a 500 Internal Error. I have changed the apache2.conf file, and 000-default.conf file. What should I do? -

Assume I have model like this: class Account(models.Model): balance = models.IntegerField() debt = models.IntegerField() history = HistoricalRecords() I'm using django-simple-history to get instance of the model as it would have existed at the provided date and time: inst = Account.history.as_of(datetime.datetime.now().date) It's working fine, but I want to get instance where debt field is represented as it would have existed at the provided date and time, and then debt field will be most recent of that date. I don't know if this is possible, didn't find anything about that. -
Prefetch the contents of files referenced by the ORM
My situation is that I'm using the Django ORM to fetch a list of objects, each with a file. I then need to access the file-data for each and every object in the list. We're hosting our files on S3, and it seems to take a long time every time I call f.read() I'm wondering, is there a way to pre-fetch the contents of the file, so that f.read() doesn't have to make another round-trip? Anything else I can do to speed this up? Any help is appreciated, and let me know if there is more I can clarify. -
How to update a Wagtail Page
I am using a wagtail_hook to update a Page object and am running into trouble. More specifically, when an end-user hits the "Save draft" button from the browser I want the following code to fire. The purpose of this code is to change the knowledge_base_id dynamically, based on the results of the conditional statements listed below. def sync_knowledge_base_page_with_zendesk2(request, page): if isinstance(page, ContentPage): page_instance = ContentPage.objects.get(pk=page.pk) pageJsonHolder = page_instance.get_latest_revision().content_json content = json.loads(pageJsonHolder) print("content at the start = ") print(content['knowledge_base_id']) kb_id_revision = content['knowledge_base_id'] kb_active_revision = content['kb_active'] if kb_active_revision == "T": if kb_id_revision == 0: print("create the article") content['knowledge_base_id'] = 456 #page_instance.knowledge_base_id = 456 # change this API call else: print("update the article") elif kb_id_revision != 0: print("delete the article") content['knowledge_base_id'] = 0 #page_instance.knowledge_base_id = 0 print("content at the end = ") print(content['knowledge_base_id']) #page_instance.save_revision().publish So when the hook code fires, it updates the draft with all the info EXCEPT the knowledge_base_id. However when I change the knowledge_base_id like this (seen commented out above) page_instance.knowledge_base_id = 0 And save it like this (also seen commented out above) page_instance.save_revision().publish() It saves the updated knowledge_base_id BUT skips over the other revisions. In short, what the heck am I doing wrong. Thanks in advance for the assist. …
