Django App hosted on IIS suddenly starts to show "Object Moved" Page plus gibberish on 302 redirect
Screenshot It's an internal Django web app is hosted on a Windows Server 2008 with IIS 7.5, with Active Directory SSO enabled. Some links in the app response with a 302. For example, if the request is to go to myapp.com/change, the server will response with a 302 and redirect to myapp.com/change?user=5. In the browser, the url field shows the myapp.com/change?user=5, but the page looks like the picture above. If I hit enter on the url field, it goes to the correct page. I have tried to troubleshoot with DevTools. When clicking on /change, server responses with a 302 followed by a 200, nothing else. The 200 is blank, with no header or body, and says "Caution: request is not finished yet". Meanwhile, there's the spinning icon showing on the chrome tab meaning it's still loading. After a few minutes, the 200 times out and the spinning stops. Nothing in the code was changed in the last couple weeks, and two days ago people started reporting this issue. It didn't happen to me at first. I tried clearing cookie and cache, using different browsers and PCs, couldn't replicate it, then there's a scheduled PC restart yesterday, and I'm getting this … -

How can I Create Django Object after a Confirmation Form
I am working a Saving App where I want user to confirm Deposit before adding it in the database. I have tried all I could but after clicking on Confirm button in the Dailog Form the system redirects me back to deposit form displaying an error that Field Can Not be Empty.

Sign in with Google integration given origin not allowed on django
I am new to the google sign in api, and I am trying to create a simple app in which users sign up/sign in using google one tap sign in and then see their name and email. I was able to get google sign in working as a static webpage on my webserver(apache), but once I moved it to django(I am using django to store the emails in a database), I get the error: [GSI_LOGGER]: The given origin is not allowed for the given client ID. I have added the url tied to my webserver to the list of authorized js origins, hence it was working as a static page from that url, but it is not working when served through django. Is the origin different when it comes from django? Also, I know that there is a way to accomplish what I want using django social auth or django all auth, but I am looking to get the one tap sign in working using this code (heavily based on these docs from google: https://developers.google.com/identity/gsi/web/guides/migration , https://developers.google.com/identity/gsi/web/guides/handle-credential-responses-js-functions ) index.html: <script src="https://accounts.google.com/gsi/client" async defer></script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script> <div id="g_id_onload" data-client_id=['my client id'] data-auto_select="true" data-login_uri=['the url which was added to js origins'] … -
Django parameters in URL
I am trying to write a delete function for my CRUD API with Python Rest Framework. In the delete I want to delete a specific item in the database, and I want it to be passed via link parameter like so: path/to/link/to/delete/post3. I did that in the url file: path("link/<int:link_pk>/", views.LinkView.as_view(), name="link_integration") Then, in the ApiView that is the code: @log_request_decorator def delete(self, request: Request, link_pk: int, **kwargs) -> JsonResponse: do_stuff() #print(social_integration_pk) return JsonResponse({}, status=204) And here is the code of the test that I am using to test it: link = "link/1/" factory = APIRequestFactory() request = factory.delete(link) view = LinkView.as_view() ---forced auth--- response = view(request) And I get this as output: TypeError: delete() missing 1 required positional argument: 'link_pk' Do someone know how to fix that? I need to have that parameter in order to do what I am supposed to. Maybe is something silly, but I don't know. If you can, please help me. Thank you -
Trying to revert from class based detail view to a function based view but I keep getting a NoReverseMatch error
I am creating a ticket project with some comment functionality and I know this sounds weird, since the tendency is usually to go from function based to class based. My problem lies in the fact that since the Detail View is designed to just be a Display View, trying to include a comment system on the same page proves to be rather difficult. Right now, I am simply trying to replicate the detail part of the ticket and I keep getting this error Traceback Traceback (most recent call last): File "C:\Users\mikha\bug_env\lib\site-packages\django\core\handlers\exception.py", line 47, in inner response = get_response(request) File "C:\Users\mikha\bug_env\lib\site-packages\django\core\handlers\base.py", line 204, in _get_response response = response.render() File "C:\Users\mikha\bug_env\lib\site-packages\django\template\response.py", line 105, in render self.content = self.rendered_content File "C:\Users\mikha\bug_env\lib\site-packages\django\template\response.py", line 83, in rendered_content return template.render(context, self._request) File "C:\Users\mikha\bug_env\lib\site-packages\django\template\backends\django.py", line 61, in render return self.template.render(context) File "C:\Users\mikha\bug_env\lib\site-packages\django\template\base.py", line 176, in render return self._render(context) File "C:\Users\mikha\bug_env\lib\site-packages\django\template\base.py", line 168, in _render return self.nodelist.render(context) File "C:\Users\mikha\bug_env\lib\site-packages\django\template\base.py", line 977, in render return SafeString(''.join([ File "C:\Users\mikha\bug_env\lib\site-packages\django\template\base.py", line 978, in <listcomp> node.render_annotated(context) for node in self File "C:\Users\mikha\bug_env\lib\site-packages\django\template\base.py", line 938, in render_annotated return self.render(context) File "C:\Users\mikha\bug_env\lib\site-packages\django\template\loader_tags.py", line 153, in render return compiled_parent._render(context) File "C:\Users\mikha\bug_env\lib\site-packages\django\template\base.py", line 168, in _render return self.nodelist.render(context) File "C:\Users\mikha\bug_env\lib\site-packages\django\template\base.py", line 977, in render return SafeString(''.join([ … -
Docker and Nginx: port 80 and 403: address already in use
I have a VPS server runs on Ubuntu, I am running multiple Django projects with Nginx and Gunicorn. Recently, I decided to deploy my latest project with Docker. Everything is working, except the port 80. I can run the website on example.com:1330 but once I change it to 80, I get this error: err: ERROR: for nginx Cannot start service nginx: driver failed programming external connectivity on endpoint project-nginx (a4417bdb121b0afb1e57e11b68dd0eb74f770ed74f654a2722f4cd74121): Error starting userland proxy: listen tcp4 0.0.0.0:80: bind: address already in use err: Encountered errors while bringing up the project.

But I lose the other Django projects that doesn't run on docker. Please, any idea? -

Apache Reverse Proxy using mod_proxy
0 Introduction I'm trying to setup a server with a main website hosted on ports 80 and 443 (let's call it example.com) and a section on this website that serves umami analytics hosted on port 3000 (let's call it umami.example.com) using a reverse proxy. I'm using Django and Apache (with mod_wsgi as hinted from the django project) and I have to setup DNS using Cloudflare. The main website works as intended, redirecting http traffic to https (more on that on the Apache section) and I'm tring to add this section under umami.example.com but every request ends up in a 404 error given by my main website.

Django Haystack different installation backends
At the Haystack docs there is a section at the installation where it indicates where your site configuration file will live and which backend to use, as well as other settings for that backend. There are mentions to some backends and I don't know which one I should choose... Solr, Elasticsearch, Whoosh, Xapian and Simple. Which one should I choose for a search engine not that complex but also not dumb. I want to look for items in my database by the title but also being able to handle typos? I want something that is open source and that does not use JavaScript. -
django.core.exceptions.ImproperlyConfigured, Requsted setting DEBUG (?)
I am getting the following error: "django.core.exceptions.ImproperlyConfigured: Requested setting DEBUG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings."

Django using global variables
I believe this question can be applied beyond the scope of Django, but Django is all I know: how to handle global 'resource' variables? I am concurrently working on a testing framework for this tutorial project and finding myself copy-pasting field labels and help text to ensure their validity. Going forward, anytime I need to modify the label, I need to manually modify it in my testing framework as well which goes against basic programming principles. For example, # My ModelForm class in /my/path/models.py class MyForm(ModelForm): def clean_field(self): data = self.cleaned_data[<my_field>] ... return data class Meta: model = MyModel fields = [<field_a>, <field_b>, ...] # copy-paste labels = {<field_a>: <label_a>, ...} # copy-paste help_texts = {<field_a>: <help_text_a>, ...} # copy-paste ---- # Corresponding SimpleTestCase in /my/path/test_forms.py class MyFormTest(SimpleTestCase): def setUp(self): self.form = MyForm() def test_field_a_form_label(self): expected = <label_a> # copy-paste fl = self.form.fields[<field_a>].label # copy-paste self.assertTrue(fl is None or fl == expected) ... In Android, your project contains a 'resource' directory which has all the static values (help text, titles, etc) used throughout the project. This directory can then be accessed from anywhere through Context, creating a single source of truth. What is the recommended approach in web development for … -
Django rendering Form object rather than form fields
Sure I've missed something obvious, but any help appreciated. I have a form model: class UserForm(forms.Form): name = forms.CharField() A view: def userform(req): context = {} context['user_form'] = UserForm() context['message'] = 'test message' return render(req, 'apps/userform.html', context) And a template: {% extends 'base.html' %} {% block title %} | User Form {% endblock %} {% block content %} <h1>Form page</h1> <form method='POST'> {% csrf_token %} {{ user_form }} <button type='submit'>Send</button> </form> {{ message }} {% endblock %} I'm pretty sure everything is connected correctly and imported as required - the 'message' property on context renders fine under the form. However, {{ user_form }} in the template renders the actual Form object instance, rather than the actual form field I'm expecting. I see: <userform.views.UserForm object at 0x7fcab17e5c10> Then the form submit button. What have I missed? Django 4, if that matters. -

Check if Djoser user exists by email
I am currently working developing a login screen where I am using djoser for authentication.

how to create class name in django formset dynamically based on foreignkey value?
How can I pass the value from the slug field from the Product model to my formset and create a dynamic class name that will contain this value? I managed to create a fixed class name form-control in each form but I don't know how to make a dynamic class so it creates the slug that is a field in the Product model. When I put "class": self.related_product it gives me 'CalculatorForm' object has no attribute 'related_product' error. My question is what should I insert here to get slug value? forms.py class CalculatorForm(forms.ModelForm): author = forms.CharField(widget = forms.HiddenInput(), required = False) created = forms.DateTimeField(widget = forms.HiddenInput(), required = False) number_of_units = forms.IntegerField(min_value=0) total_price = forms.IntegerField(widget = forms.HiddenInput(), required = False) class Meta: model = CERequest fields = ('author', 'created', 'related_product', 'related_component', 'number_of_units') def __init__(self, *args, **kwargs): super(CalculatorForm, self).__init__(*args, **kwargs) for field in self.fields: new_data = { "class": 'form-control' #how to pass slug value here? } self.fields[str(field)].widget.attrs.update( new_data ) RequestFormset = formset_factory(CalculatorForm, extra=0, can_delete=False) models.py class CERequest(models.Model): author = models.CharField(max_length=255, blank=True, null=True) related_component = models.ForeignKey(CostCalculator, on_delete=models.CASCADE) number_of_units = models.IntegerField(default=0) related_product = models.ForeignKey(Product, on_delete=models.CASCADE) class Product(models.Model): ... slug = models.SlugField(max_length=250) -

What's the proper way to define this relationship in Django?
Okay, long story short, I have a model with - among other things - the following: class Connection(Model): currentnas = models.ForeignKey(NAS, null = True, blank=True, default = None, on_delete=models.SET_NULL, related_name='active') class NAS(Model): # Various data fields currentnas is, as the name suggests, the representation of the NAS that that connection is currently connecting through. This part works fine, however, now I'm trying to add another field to Connection: permittednas = models.ManyToManyField(NAS) The intention is to check during an authentication step whether currentnas matches one of the elements in permittednas; however, my first attempt to make this work ran into a snag when python informed me that TypeError: argument of type 'ManyRelatedManager' is not iterable. To clarify, I have a number of Connections a, b, c, d and a number of NAS objects 1, 2, 3, 4, and I want to be able to say that (for example) a is permitted to connect via 1, 2 and 4; b may connect via 2 and 4; c can connect via all four, and d may only connect via NAS 1. -
Django admin Valid form with funtion clean

Here is my model: class TestRange(models.Model): SERVICE = [ ('s1', 'Service 1'), ('s2', 'Service 2') ] service = models.CharField(max_length=2, choices=SERVICE) SDA = [ (False, 'NO SDA'), (True, 'SDA') ] sda = models.BooleanField(choices=SDA) number_start = models.CharField(max_length=10, validators=[valide_phone_number]) number_end = models.CharField(max_length=10, validators=[valide_phone_number]) def clean(self): if int(self.number_end) < int(self.number_start): raise ValidationError({'number_end': _("The end number must be greater than or equal to the start number")}) if self.sda and len(self.number_start)!=10: raise ValidationError({'number_start': _("A SDA number consists of 10 digits")}) super(TestRange, self).clean() Since the definition of this function the default validation of the admin form no longer works, I no longer have to check the fields of the form before registration.
