How do I implement Google Sign-In, keep getting Forbidden CSRF Error
I'm building a simple Login page using Python and Django. I want to give the users the choice to login using either the Django account or Google Sign-In. I've build some simple HTML and functions to flow between 4 pages: Main, login_success,logout_success and already_logged_in As far as I've understand, I've set up at the very least a button on my login page, with some relevant scripts. So, then I deploy to my Google Cloud, access the site, see the button and click on it and it redirects me to a Google Sign-In page where I can choose my account. I click on the account and I get a Forbidden: CSRF Error. Am I missing something? I am not sure how to debug this. This is my Main login HTML.(I'm not sure if the rest are needed to be shown?) {% load i18n %} {% block content %} <!DOCTYPE html> <html> <meta charset="UTF-8"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap-theme.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script> <link href="https://fonts.googleapis.com/css?family=Open+Sans" rel="stylesheet"> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <link rel="stylesheet" type="text/css" href="https://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" media="all" /> <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script> <head> <title>Google Signin Testing</title> <style> .left { float: left; width: 40%; padding-left:32%; padding-top:13%; height: 75% } .right { float: left; width: 40%; padding-top:5%; height: 100% … -
Can I detect ManyToManyField mutations before they are applied?
I have a Django app that broadcasts changes of some of its models to its clients, to keep them up-to-date. I have a separate app for that, that binds to the post_save signal of these models and triggers the broadcast. Problems have come with models with ManyToManyFields. I am not very familiar with Django's handling of this but I understand that these fields are actually updated after the model is saved. I was able to use the m2m_changed signal to react to the post_* actions and dispatch the broadcast after the object is all up-to-date. However, in the post_save handler, I still need to detect that the m2m field is going to be mutated, to avoid broadcasting incomplete data. How can I detect this , either in the post_save signal handler or the model's save method ? Is there a way to raise a flag on an object when a m2m field is about to be mutated ? Here's what I've tried : Handle the pre_* actions of the m2m_changed signal to detect incoming mutation of the field but that does not work, because the signal gets fired after post_save, which is too late (data has already been broadcasted).

Issue with mock return value in py test?
I have the following post function in my view and I want to mock the return values of customer.get_customer_data and customer.update_customer_data in my test function. However, it seems like only one of the mock return values is getting allocated. def post(self, request, *args, **kwargs): try: data = request.data status_code, response = customer.get_customer_data( data["customer_id"], "id," ) if status_code == 401: auth.generate_new_access_token("buyer") status_code, response = customer.get_customer_data( data["customer_id"], "id," ) if status_code == 401 or status_code == 200: id = response[0]["message"][0]["id"] status_code, response = customer.update_customer_data(id, data) tests.py @patch("app.views.customer.get_customer_data") @patch("app.views.customer.update_customer_data") def test_customer_view(self, mock_customer_data, mock_update_customer_data): customer_update_data = { .... } mock_customer_data.return_value = 200, [{"message": [{"id": 1234}]}] mock_update_customer_data.return_value = 200, 'Success' req = RequestFactory().post("/app/customer/create/", customer_update_data, content_type='application/json') resp = views.EditCustomerView.as_view()(req) resp.render() assert json.loads(resp.content) == "Success" assert mock_customer_data.called assert resp.status_code == 200 I am getting the following error when I run the test id = response[0]["message"][0]["id"] TypeError: string indices must be integers Seems like this one is getting called for the wrong function. It's getting patched with the get_customer_data function instead of update_customer_data What could I be doing wrong? -

Django data from RichTextField renders with html tags
I have a website which in its one page it renders data from a specific object which has 1 integer, 1 string and 2 rich text values (ckeditor, RichTextField). The class is represented belov; class Chapter(models.Model): chapter_id = models.IntegerField(primary_key=True, default=None) chapter_title = models.CharField(max_length=100, default=None) chapter_text = RichTextField(default=None) chapter_footnotes = RichTextField(default=None, blank=True) When I try to render the data from RichTextFields it renders with the html elements as a text. Example: <p><span style="color:#757575"><span style="background-color:#ffffff">Why a sword?&nbsp;</span></span></p> <p><span style="color:#757575"><span style="background-color:#ffffff">There are so many different weapons in the world, so why did I choose the sword?&nbsp;</span></span></p> <p><span style="color:#757575"><span style="background-color:#ffffff">That&#39;s because swords represent perfection.&nbsp;</span></span></p> <p><span style="color:#757575"><span style="background-color:#ffffff">A sword has two edges.&nbsp;</span></span></p> <p><span style="color:#757575"><span style="background-color:#ffffff">One edge to hurt the enemy, one edge to protect me.&nbsp;</span></span></p> <p><span style="color:#757575"><span style="background-color:#ffffff">It protects me by killing my enemies.&nbsp;</span></span></p> <p><span style="color:#757575"><span style="background-color:#ffffff">That is the purpose of a sword.&nbsp;</span></span></p> <p><span style="color:#757575"><span style="background-color:#ffffff">And that is exactly how I use my chosen weapon, my sword.&nbsp;</span></span></p> How can I make it so that It renders itself without showing but applying its html element tags.

Why does Django/Postgres appear to save but doesn't, gives 'connection already closed'?
I'm using Django + Postgres on Windows 10 WSL Ubuntu 18.04.5 LTS. Saving data to postgres seems to work, yet when I access the table using psql on the command line, the data isn't there. Refreshing the webpage (reloading Django) also shows the old data previous to the save. There are no errors in the postgresql log. I don't have caching explicitly turned on in Django's settings.py. It all worked perfectly for years, but to be sure I upgraded Django to 3.2.6, Python to 3.8.11, postgresql to 12, and psycopg2 to 2.9.1, plus the necessary dependencies. Same result. Here's the code in Django: try: nodeToUpdate.save() # Hit the database. node = Node.objects.get(pk=itemID, ofmap=mapId) # Retrieve again to confirm it was saved # This shows the correct data: print("STORE TO MAP:" + str(node.ofmap_id) + " NODE:" + str(node.id) + " label:" + str(node.label)) except psycopg2.InterfaceError as err: print(str(err)) raise Exception(err) except ValidationError as err: raise Exception(err) The clue to what's going on comes when I run unit tests: Traceback (most recent call last): File "/var/www/mysite/venv/lib/python3.8/site-packages/django/db/backends/base/base.py", line 237, in _cursor return self._prepare_cursor(self.create_cursor(name)) File "/var/www/mysite/venv/lib/python3.8/site-packages/django/utils/asyncio.py", line 26, in inner return func(*args, **kwargs) File "/var/www/mysite/venv/lib/python3.8/site-packages/django/db/backends/postgresql/base.py", line 236, in create_cursor cursor = self.connection.cursor() **psycopg2.InterfaceError: connection … -

Django admin object change action
I am developing a courier management service using Django. So far, I have made three models, Customer DelveryAgent Parcels Here is the Parcel model: class Parcel(models.Model): type = models.CharField(max_length=20) city = models.CharField(max_length=20) street = models.CharField(max_length=100) zip = models.CharField(max_length=100) email = models.CharField(max_length=100) phone = models.CharField(max_length=100) status = models.CharField(max_length=100, choices=STATUS, default='pending') booked_by = models.ForeignKey(Customer, on_delete=models.CASCADE) delivery_agent = models.ForeignKey(DeliveryAgent) Initially, the parcel status is pending, and the delivery agent is None. When the admin assigns a delivery agent to the parcel from the admin site, I want the relative customer to get notified with the details of the delivery agent. How can I do that? -

Unable to delete object from Django admin panel with MongoDB
I have a Django project using a MongoDB connected by Djongo. I created a simple model which looks like: from django.db import models # Create your models here. class Property(models.Model): name = models.CharField(max_length=128, blank=False) property_type = models.CharField(max_length=24, blank=True) include_on = models.CharField(max_length=256, blank=True) format_example = models.TextField(blank=True) notes = models.TextField(blank=True) After registering the model by using the line admin.site.register(Property) in the admin.py file I end up seeing my model appear.

It also appears on the admin panel but it looks like: Property object (None) If I select the property I get an error that says: Property with ID “None” doesn’t exist. Perhaps it was deleted? If I try to delete the property I get a ValueError with error of: Field 'id' expected a number but got 'None'. Since I am currently learning Django/MongoDB I actually ran across the ValueError once before. The fix was to delete the entire database and start over. The issue is I don't want to run into this in the future and want to know what I have to do to fix it, or …
