Scheduled POST with django and ajax
Okay guys, I'm pretty stumped with this one! So, I am trying to routinely post the contents of a txt file onto a website. (IE update the file daily and post the new one) I am using django as the framework and have everything working..... almost. Following this question: Periodically fetch data and display it with Django I set up the views, templates, and urls so that $.ajax is called whenever I load the page. And that part works! If I manually load the page into a browser, the data is updated and displayed correctly. However, automating it has been problematic. If I had to guess, I would say that.. for some reason, $.ajax is not being called when there is not a browser. Here is the requests.py code: import requests login_url = "http://127.0.0.1:8000/login/" soup_url = "http://127.0.0.1:8000/soups/pull/" test_url = "http://127.0.0.1:8000/profiles/myusername" UN = 'myusername' PW = 'mypassword' with requests.session() as client: # get the login page client.get(login_url) # save session credentials csrftoken = client.cookies['csrftoken'] login_data = {'username':UN,'password':PW,'csrfmiddlewaretoken': csrftoken} # login client.post(login_url, data=login_data) client.get(test_url) # get the page that loads $.ajax client.get(soup_url) And, the $.ajax request comes from: {% extends "base.html" %} {% block script %} <script> $(document).ready(function(){ function pullSoup(){ var token … -
Python Bots plugins stop working after unzipping and zipping back
Python Bots plugins stop working after unzipping and zipping back on Linux. I checked original zip file and zip after unzipping/zipping and they have different size and look different in DIFF. Python gets stuck trying to read same plugin after simply zipping and unzipping it. It has probably something to do with character encoding (author of bots edi lives in Europe), but I am new to python and don't know how you Python guys deal with this issue.Google search did not produce any results for me. Please help. -
can it be possible to use autheticate method in django with only one parameter as email?
As mentioned above that I want to use django "authenticate" method with one parameter as email because I use mastodon api for authenticating user and I already got access token from mastodon. After this I just want to check that whether that email is present in django's user table or not with the help of any django method. I used authenticate method but it fails in the use case of password reset. Is there any method in django which can authenticate user with only email. I mention my code below if any modification in the code make that code runs would be appreciable. Django Code: CHECKING CLIENT CREDENTIALS########## mastodon_var = mastodon.Mastodon( client_id='gnowsys_ndf/ndf/NROER-client_cred.secret', api_base_url='https://member.metastudio.org' ) access_token = None ####GET ACCESS FROM MASTODON HERE####### try: access_token = mastodon_var.log_in( Username, Password, to_file='gnowsys_ndf/ndf/NROER-access_token.secret', ) except Exception as e: print e pass name = Username email = Username password = Password # userna = mastodon_var.u"username" # print userna #######IF USER GETS ACCESS TOKEN THEN FOLLOWING CODE WILL BE EXECUTED########## if access_token: if User.objects.filter(username=name).exists(): ####SECOND AND BY-DEFAULT LAYER FOR AUTHENTICATION user = authenticate(username=name,password=password) if user is not None: if user.is_active: login(request, user) return HttpResponseRedirect( reverse('landing_page') ) else: HttpResponse("Error1") return HttpResponseRedirect( reverse('landing_page') ) else: member = User.objects.create_user(name,email,password) … -
PostgreSQL ALTER SEQUENCE using psycopg2 in django
I am trying to alter sequence of id field in my table using psycopg. This is works fine on my local server, but not working on production. I am not getting exceptions, the sequence is just not restarting. def alter_sequence(last_id): try: dbname = settings.DATABASES['default']['NAME'] user = settings.DATABASES['default']['USER'] host = settings.DATABASES['default']['HOST'] password = settings.DATABASES['default']['PASSWORD'] port = settings.DATABASES['default']['PORT'] connection = psycopg2.connect( dbname=dbname, user=user, password=password, host=host, port=port, ) cursor = connection.cursor() cursor.execute('ALTER SEQUENCE "gs_requests_id_seq" RESTART WITH {}'.format(last_id)) connection.close() except Exception as e: print(e) pass I double-checked the database settings - its correct. Other database operations, performed by django ORM with this settings is works fine. I think, this is not enough information about my project settings but dont know what information I need to specify. I have postgres 9.6 on my local computer and 10.1 on production. -

Tag suggestion system using Django
I'm trying to develop a tag system similar to StackExchange. Since I'm using Django, I can think in two ways to suggest tags while a user is typing: Pass all tags in the context to the template and handle using JS or similar Query the database while user is typing I expect to have around 500 tags, which way would be faster? Is there a better way to do this? Thank you. -

Django trouble collecting static using Whitenoise and pushing to Heroku - Getting UnicodeDecodeError
Before Installing Whitenoise, I could collect static and everything works perfect locally, but after installing Whitenoise and attempting to push my files to heroku for production, I got the following error: FileNotFoundError: [Errno 2] No such file or directory: '/tmp/static/static' I then attempted to collect static through my terminal to troubleshoot and got this error: UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 0: invalid start byte I'm new, and it's tough to understand where to start to troubleshoot this. I tried messing around with my static directory settings with no luck, but it seems that the location is fine, but whitenoise is failing to collect anything because of this Unicode error and that's why I can't push it to Heroku. I'm unsure of how to figure out where this error is located from the traceback, or how to fix it.

Django: How is a RelatedManager object instantiated?
Suppose I have two models: Book and Author. If I now added a ForeignKey field to Book connecting it to Author, and instantiated a Book object - then I also have access to that Book object through the Author object it is connected to (via .book_set, if no related_name specified). From what I have understood reading the documentation, this access is provided through a Related Manager object on the Author object. When is that RelatedManager-object created? Or is it already an object on each Author object, but gets connected to each Book object upon instantiation of a new Book? If so, how does it get connected to the Book object? This is not mentioned in the documentation to my knowledge. In the documentation: If a model has a ForeignKey, instances of the foreign-key model will have access to a Manager that returns all instances of the first model. -
Django Middleware that redirects to https
I'm trying to build some middleware in my Django project that redirects the user to a 'https' link if their request isn't initially to https. The code below is not redirecting the user under any of the tests that I've run (i.e. user enters 'www.example.com', 'http://example.com,', http://www.example.com', etc. Can any of you spot the problem with this code? Normally, I'd use print statements to see what the path is being set to, but I can't do that on my live server (or at least I don't know how to): from django.http import HttpResponseRedirect from django.utils.deprecation import MiddlewareMixin class RedirectMiddleware(MiddlewareMixin): def process_request(self, request): host = request.get_host() if host == 'www.example.com' or 'example.com': path = request.build_absolute_uri() domain_parts = path.split('.') if domain_parts[0] == 'http://www': path = path.replace("http://www","https://www") return HttpResponseRedirect(path) elif domain_parts[0] == 'www': path = path.replace("www","https://www") return HttpResponseRedirect(path) elif domain_parts[0] == 'http': path = path.replace("http","https") return HttpResponseRedirect(path) elif domain_parts[0] == 'example': path = path.replace("example","https://www.example") return HttpResponseRedirect(path) else: pass else: pass Thanks again guys -

Django is not seeing my MySQLdb module on CentOS 7 with mysqlclient installed and database working

Why table shows no data using a custom table template in django-tables2?
I am using django-tables to create a table from my model to display it on a page. I have created the folowing tables.py file: class OpenBetsTable(tables.Table): class Meta: model = Bet fields = ("date", "time", "competition", "home", "visitor", "bookie", "bet", "stake", "odds") attrs = {"class": "table table-striped table-sm table-bordered"} empty_text = "Nothing to display" I have a class-based view that contains the following: queryset = user_bets.filter(status__name="New").order_by("-timestamp") table = OpenBetsTable(queryset) RequestConfig(self.request, paginate={'per_page': 10}).configure(table) context["table"] = table In the page's template I have added {% load django_tables2 %} and {% render_table table %} to render the table. Everything works correctly until this point. I want to use a custom template for the table so I added template_name in OpenBetsTable, using one of the templates provided with django-tables2: class OpenBetsTable(tables.Table): class Meta: model = Bet template_name = "django_tables2/table.html" fields = ("date", "time", "competition", "home", "visitor", "bookie", "bet", "stake", "odds") attrs = {"class": "table table-striped table-sm table-bordered"} empty_text = "Nothing to display" Everything still works correctly.

How do I mock a third party library inside a Django Rest Framework endpoint while testing?
The user creation endpoint in my app creates a firebase user (I have a chat room inside the app, powered by firebase) with the same id as my django user. from django.contrib.auth.models import User from rest_framework import generics from rest_framework import permissions from apps.core.services import firebase_chat class UserCreate(generics.GenericAPIView): permission_classes = [permissions.AllowAny] @transaction.atomic def put(self, request): user = User.objects.create(**request.data) firebase_chat.create_user(user) firebase_chat is a wrapper I created around the standard firebase library. I'm writing my tests like recommended in DRF's guide: from django.urls import reverse from django.test import TestCase from rest_framework.test import APIClient class UserCreateTest(TestCase): def test_user_create__all_valid__user_created(self): client = APIClient() client.force_authenticate(user=User.objects.create(username='test')) response = client.put(reverse('user-create')) self.assertTrue(response.data['something']) However, this leads to creating an actual user in Firebase. Not only this fails the test (the firebase library throws an exception), it also hits the actual firebase server, filling it with test data.
