How can I modify this script so that all changes are deployed to django GAE (Google App Engine)?
Background: I have this script called run_fabric that runs at the end of a Github action pipeline and deploys changes in my Django app. I didn't write this code but I think it must only copy the html files from repo to the nginx server and then restarts the server. Unfortunately I try to change python files and I never see my code changes deployed. I think it's because it only copies html files over (I'm trying to make changes to IPN paypal gateway in the hooks.py file so I can update the price on checkout but I don't see this change reflected) Is there a way I can modify this script below to include all python files as well as html so I can see code changes deployed to my Django app hosted on GAE? I've replace ipaddress with my static ip address of GAE for security reasons. Code is below: from fabric import Connection import os import glob x = glob.glob("./web/templates/*.html") c = Connection("ipaddress", port=22, user="fady", connect_kwargs={'look_for_keys': False,'key_filename':'priv'}) for i in x: out =i.split("/")[-1] c.put(f"{i}",f"/home/fady/soild/web/templates/{out}") res = c.run("sudo service uwsgi restart") res = c.run("sudo service nginx restart") print("Done") My project structure is like /root ./run_fabric.py (script above) ./manage.py … -
'list' object has no attribute 'startswith' with Django and scrapy integration
I am getting this peculiar error after I try to runserver once I have finished web-crawling as my web-crawler is connected to django : Exception in thread django-main-thread: Traceback (most recent call last): File "/Users/usr/opt/anaconda3/lib/python3.8/threading.py", line 932, in _bootstrap_inner self.run() File "/Users/usr/opt/anaconda3/lib/python3.8/threading.py", line 870, in run self._target(*self._args, **self._kwargs) File "/Users/usr/cruises/venv/lib/python3.8/site-packages/django/utils/autoreload.py", line 64, in wrapper fn(*args, **kwargs) File "/Users/usr/cruises/venv/lib/python3.8/site-packages/django/core/management/commands/runserver.py", line 134, in inner_run self.check(display_num_errors=True) File "/Users/usr/cruises/venv/lib/python3.8/site-packages/django/core/management/base.py", line 487, in check all_issues = checks.run_checks( File "/Users/usr/cruises/venv/lib/python3.8/site-packages/django/core/checks/registry.py", line 88, in run_checks new_errors = check(app_configs=app_configs, databases=databases) File "/Users/usr/cruises/venv/lib/python3.8/site-packages/django/core/checks/urls.py", line 107, in check_url_settings value = getattr(settings, name) File "/Users/usr/cruises/venv/lib/python3.8/site-packages/django/conf/__init__.py", line 93, in __getattr__ val = self._add_script_prefix(val) File "/Users/usr/cruises/venv/lib/python3.8/site-packages/django/conf/__init__.py", line 140, in _add_script_prefix if value.startswith(("http://", "https://", "/")): AttributeError: 'list' object has no attribute 'startswith' It seems to be an error located in one of the django files rather than from my script.

Heroku can not find generated file
I have a Django project which generates a PDF file. This below is the corresponding code: def createPDF(name): current_path = os.path.dirname(os.path.dirname(__file__)) template = get_template(f'src.tex') context = { 'content': name, } rendered_tpl = template.render(context).encode('utf-8') process = subprocess.Popen( ['pdflatex', '-output-directory', f'{current_path}/templates'], stdin=PIPE, stdout=PIPE, ) process.communicate(rendered_tpl) When I run the local server and run my function the PDF is saved in my templates directory. However, after deploying on Heroku, and generating the PDF the PDF is not found. I tried to look for it in the bash, but it is just not there. What is wrong? -
CORS headers not showing up in my request/response on Django
I've made the following CORS implementation on my Django project using django-cors-headers. CORS_ORIGIN_ALLOW_ALL = False CORS_ALLOWED_ORIGINS = [] MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', .... ] INSTALLED_APPS = [ ... 'corsheaders', ] For some reason, I don't see the effect of these headers (I don't have Access-Control-Allow-Origin in my headers). I print out the request and response headers in my view. This is my view: def payment(request, *args, **kwargs): print(request.headers) params_in = json.loads(request.body.decode('utf-8')) headers_in = { 'Content-Type': 'application/x-www-form-urlencoded', 'Authorization': 'Bearer key, } response = requests.post('https://url.com/v1/endpoint', headers=headers_in, data=params_in) resp_out = Response(response.json()['value']) print(resp_out.headers) return resp_out My request headers are ['Host', 'Connection', 'Content-Type', 'Origin', 'Accept-Encoding', 'Cookie', 'Accept', 'User-Agent', 'Referer', 'Accept-Language', 'X-Request-Id', 'X-Forwarded-For', 'X-Forwarded-Proto', 'X-Forwarded-Port', 'Via', 'Connect-Time', 'X-Request-Start', 'Total-Route-Time', 'Content-Length'] and my only resp_out header is 'Content-Type'. Why could this be? What am I missing? -
Changing language in Django i18n
I was working on an ecommerce website and it has two language options. I am fetching data using an sql code I found on youtube. Let me describe how it works; When a vendor adds a product, he must fill the forms on both languages. If the vendor fills only the English form, his product will be seen if a user uses English. If the user switches the language his product disappears. How can I correct this? What I want is, If the 2nd language is filled, bring that. If the English form is only filled, it should bring the English form not make it disappear. Here is the sql code in my views: defaultlang = settings.LANGUAGE_CODE[0:2] currentlang = request.LANGUAGE_CODE[0:2] if defaultlang != currentlang: setting = SettingLang.objects.get(lang=currentlang) products_lat = Product.objects.raw( 'SELECT p.id, p.price, p.is_featured, l.title, l.description,l.slug ' 'FROM product_product as p ' 'LEFT JOIN product_productlang as l ' 'ON p.id = l.product_id ' 'WHERE l.lang=%s ORDER BY p.id DESC LIMIT 50', [currentlang]) prod = Product.objects.raw( 'SELECT p.id,p.price, l.title, l.description,l.slug ' 'FROM product_product as p ' 'LEFT JOIN product_productlang as l ' 'ON p.id = l.product_id ' 'WHERE p.is_featured=%s and l.lang=%s ORDER BY p.id DESC LIMIT 20', [True, currentlang]) Thanks in … -

Django Specific Request URL fails after working properly on a localhost
I have been working on a Django python application which I recently published to a public domain. Beforehand, I had tested my code, including a bit of code which records a user's signature after they draw it on a canvas, sends the signature to the server through the URL encoded in base64, and decodes it on the otherside. After publishing, I am having some trouble sending this long encoded base64 URL. First, I overcame the Apache2 issue 'Request URI Too Long' by editing my apache2.conf: AccessFileName .htaccess LimitRequestLine 50000 Now I simply get '404 Not Found - The request URL was not found on the server'. The URL should be fine, in fact, it finds the URL just fine when I delete some of the length at the end of the URL. Of course, it can then no longer decode the URL. As you can see from my Django error log, there is no POST or GET request, although I am POSTing the code from a form on the page. I feel that is might be the underlying issue. I tried using javascript to POST as shown here. <form action="/UserDashboard/SaveSignature/" id="FormSignature" method="POST" style="width: 60%; margin-left: 20%; margin-right: 20%; height: 60%;"> … -

I'm currently setting up my project for production and I'm stuck because the 'collectstatic' command is missing from manage.py commands. Entering './manage.py collectstatic' in the shell gives me this error Unknown command: Unknown command: 'collectstatic' Type 'manage.py help' for usage. so I check './manage.py help' and I get this response: Type 'manage.py help <subcommand>' for help on a specific subcommand. Available subcommands: [django] check compilemessages createcachetable dbshell diffsettings dumpdata flush inspectdb loaddata makemessages makemigrations migrate runserver sendtestemail shell showmigrations sqlflush sqlmigrate sqlsequencereset squashmigrations startapp startproject test testserver As you can see 'collectstatic' is missing from the list, how can I correct that? thanks and have a nice day! -

ValueError at /post/politics Field 'id' expected a number but got 'politics'
I have a template posts.html {% extends 'base2.html' %} {% block posts %} <div class="row"> <div class="leftcolumn"> <div class="cardpost"> <h1>{{posts.title}}</h1> <h5>{{posts.created_at}}</h5> <div class="fs-4">{{posts.body | safe}}</div> </div> </div> </div> {% endblock %} posts.html extends base2.html, because I want the posts.html to have nav bar functionality <nav id="navbar" class="navbar"> <ul> <li><a href="about">About</a></li> <li><a href="guestposting">Guest Posting</a></li> <li class="dropdown"><a href=""><span>Categories</span> <i class="bi bi-chevron-down dropdown-indicator"></i></a> <ul> <li><a href="tech">Tech</a></li> <li><a href="bizconomics">Bizconomics</a></li> <li><a href="politics">Politics</a></li> <li><a href="religion">Religion</a></li> <li><a href="sports">Sports</a></li> </ul> </li> <li><a href="contactform">Contact</a></li> </ul> above is a section of the nav bar which is on base2.html, and also on the index.html. It works perfectly in the index.html. But when the user is on the posts.html-> path('post/str:pk', views.post, name='post') and they click politics category for instance, I get this error: ValueError at /post/politics Field 'id' expected a number but got 'politics'.
