Django "No Patterns" / Circular Import Error
I've scoured all of the issues I can find about this error and tried all of the solutions, yet none (save one; more on that later) worked for me. Every time I start up my app, I get the following error: django.core.exceptions.ImproperlyConfigured: The included URLconf 'gamerank.urls' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import. I've checked my files for circular imports, and cannot find any at all. voting/urls.py only imports voting/views.py voting/views.py imports voting/models.py, voting/helpers.py, and voting/forms.py voting/models.py imports from libraries only voting/helpers.py imports from libraries only voting/forms.py imports from voting/models.py (which does not import from voting/forms.py) This answer works for me, but I cannot access any of my application after that (because I just commented out the routes), so it's not really a solution in my case. Here are some of my files: voting/urls.py from django.urls import path from . import views app_name = 'voting' urlpatterns = [ path('', views.index, name="index"), # auth routes path("login", views.login_view, name="login"), path("logout", views.logout_view, name="logout"), path("register", views.register, name="register") ] gamerank/urls.py from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', … -
Is it possible to map all static files or url routes of a website?
I want to make a few static files available in my server, but I don't want people to access it unless they know the exact URL. This is meant to work like a game, solve a puzzle and move to the next phase by finding out the URL. Surely there are several similar games in the web. What I'm worried is if someone could just avoid the puzzle by "mapping" all the static files in a server. Is that possible? [Assuming the puzzle solution would lead to a static file served] I would like to extend the same question for URL routes, is it possible to discover all the url routes of a website? For example I have mysite.com and mysite.com/hidden/solution.html if there are no links to the second URL, can someone get this information? [Except bruteforcing] I'm hosting this page using AWS lightsail (django and apache). Is there something I can/need to do in the django/apache side to prevent this? -
Pycharm Django CSS not updating after adding git repo
I am creating a website and I was designing it without a repository set up originally. Now, I have it in a git repo and suddenly, when I try to refresh the page (with dev tools open and cache disabled) my CSS and HTML changes have no affect. I have to stop the server, close the webpage, then re-run the server and open it again to see changes. Anyone experienced this? Not sure what gives. -

Django Forms: field_order fails to work in forms.py
My field_order variable fails to correctly set the order. I'm trying to reorganize the form so that the bottom two fields are at the top of the form, as illustrated here: Here is my class from forms.py.

Passing an additional field through a model form without adding it to the model
I'm trying to figure out how to add a field to a model form without adding the field to the model itself. I just need to pass in this extra field to the view it returns. My django project has a page where the user uploads a text file which gets saved to the DB (the file upload form is the model form). It then returns a page where the important content from the text file is displayed. I want to add a dropdown on the same page as the file upload form that allows the user to select an option for how the content should be displayed when it returns the next page. I don't want this dropdown to be part of the model for the text file as I don't need to save it to the db. I'm having trouble figuring out how to pass this option into the view without adding it to the model itself. Upload form: <form method="POST" enctype="multipart/form-data" id="text-upload-form"> {% csrf_token %} {{ form.as_p }} <label for="display-type">Display type</label> <select id="display-type" name="display-type" form="text-upload-form"> <option value="highlighted">Highlighted display</option> <option value="dark">Dark display</option> </select> <button type="submit" class="save btn btn-default">Save</button> Views.py def parser(request): if request.method =='POST': text_upload = TextFileForm(request.POST, request.FILES) … -

Django and jQuery: jQuery not working, but receiving no errors
I cannot figure out why my jQuery script isn't working. I've read through a bunch of stackOverflows but haven't been able to fix this issue. I have a form, and when a checkbox is checked, I want to enable a form field with the id div_id_newLockName. If the checkbox is unchecked, I want the form field to be disabled and greyed out. The checkbox has id div_id_newNameBool I have written code that I think should work, but it doesn't. I'm not receiving any errors though, which makes troubleshooting difficult. I'm hoping a second set of eyes can help. A picture of what the form looks like can be found here: In this picture, the "change name?" checkbox corresponds with div_id_newNameBool, and the "Lock Name" char field is what I want to toggle enable or disable. base.html (contains jQuery script) <!doctype html> <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script> </head> <style> <!-- unimportant css stuff --> </style> <body class="w3-content" style="max-width:1200px"> <!-- !PAGE CONTENT! --> {% block content %}{% endblock %} <!-- End page content --> </div> <script> $(document).ready(function(){ if ($("#div_id_newNameBool").is(':checked')){ $("#div_id_newLockName").prop("disabled", false); } else { $("#div_id_newLockName").prop("disabled", true); alert("DISABLED"); } }); </script> </body> </html> HTML page for form {% extends "homepg/base.html" %} {% load crispy_forms_tags … -
How to get reference to object in django-restframework APIView
