Getting rid of port in URL for django installation in production
I'm trying for the first time to deploy my Django application on a server but so far I wasn't able to get rid of port in my URL. Right now I'm using Gunicorn with Nginx with the following configuration. Nginx /etc/nginx/sites-enabled/site.conf server { listen 8000; server_name example.com; location = /favicon.ico {access_log off;log_not_found off;} location /static/ { root /home/webapp/um; } location /media/ { root /home/webapp/um; } location / { include proxy_params; proxy_pass http://unix:/home/webapp/um/um.sock; } } /etc/nginx/proxy_params proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; Gunicorn /etc/systemd/system/gunicorn.service Description=gunicorn service After=network.target [Service] User=root Group=www-data WorkingDirectory=/home/webapp/um/ ExecStart=/root/um/bin/gunicorn --access-logfile - --workers 3 --bind unix:/home/webapp/um/um.sock um.wsgi:application [Install] WantedBy=multi-user.target Gunicorn binding gunicorn --bind 0.0.0.0:8000 um.wsgi:application Changing port 8000 with port 80 in /etc/nginx/sites-enabled/site.conf gives me a 404 on nginx. Using port 8000 I'm able to see the site using http://example.com:8000/myapp but I'm aiming at using http://example.com/myapp as my address. As a side note, the VPS I'm installing the app on came with Plesk already installed with which I'm also not familiar with. I don't know if Plesk might be interferring in catching traffic from port 80. Thanks in advance -
Override parent css settings using child gives unknown property name
I'm trying to override the parent settings of a dropdown menu using a child class in CSS. Unfortunately, when I try to do this it gives me an "unknown property name" error on the child class, even though I use the exact same property on the parent class. The CSS code looks like: .dropdown { position: relative; display: inline-block; } .dropdown-content { display: none; position: absolute; overflow: hidden; min-width: 160; min-heigth: 100; background-color: #f9f9f9; box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2); padding: 12px 16px; z-index: 1; left:20%; } .test { min-width: 1080; min-heigth: 480; } .dropdown:hover .dropdown-content { display: inline-block; } And the HTML code (django template format) looks like: {% for info in infos %} <div class="dropdown"> <a href="#">dropdown item</a> <div class="dropdown-content"> {% if info.2 == "img" %} <!-- display image --> {% elif info.2 == "gif" %} <div class="test">Gifs and Videos are disabled for preview.</div> {% endif %} </div> </div> {% endfor %} In which info.2 will always contain either the string "gif" or "img". I have not yet implemented the image yet. However, if I use inspect element I get the following error: Which does not make any sense to me, as the css within the dropdown-content class … -

Django custom authentication using an external API endpoint
I have an API endpoint from my company that takes username and password and returns 200 response if the user is authenticated. The response body has all details about the user like user_id, name etc. Another endpoint allows a GET request with user_id as a parameter and tells if user is authenticated. For login: I use the first endpoint with POST request to check response code and also set user_id in my session so that i can later use this user_id to send a GET request to see if user is still authenticated. How can I use this in combination of login_required decorator to make sure user is authenticated for all the views in my application? Or is there any other way I can customize middleware.py for this functionality? -
get_initial() function simplification
I am populating a form with instance objects of another model like this: class ProcessingCreate(generic.CreateView): model = ProcessingActivityInstance template_name = 'dpapp/processing-create.html' fields = '__all__' def get_initial(self): initial = super(ProcessingCreate, self).get_initial() initial.update({'processing_toptype': ProcessingActivity.objects.get(id=self.kwargs['pk']), 'processing_type': ProcessingActivity.objects.get(id=self.kwargs['pk']), 'processing_description': ProcessingActivity.objects.get(id=self.kwargs['pk']), 'processing_purpose': ProcessingActivity.objects.get(id=self.kwargs['pk']), 'processing_category': ProcessingActivity.objects.get(id=self.kwargs['pk']), 'processing_legalbasis': ProcessingActivity.objects.get(id=self.kwargs['pk']), 'processing_retention': ProcessingActivity.objects.get(id=self.kwargs['pk']), }) return initial This code works but I suspect there is a cleaner way to reach the same result and I don't find it. Could someone enlighten me please? Thank you very much ! -

Django radio buttons appearing as bullet point list, inside mark_safe()
Background I have used 'mark_safe()' inside a form in order to display bullet points in my form label: class FormFood(forms.Form): CHOICES = [ (1,'Yes'), (2, 'No')] response = forms.ChoiceField(widget=forms.RadioSelect, label=mark_safe("Do you like any of these foods? <ul><li>Pasta</li><li>Rice</li><li>Cheese</li><</ul>"), choices=CHOICES) This outputs as: The problem As you can see above, bullet points are now also appearing next to 'Yes' and 'No' despite me not wanting this. Inspecting the elementing reveals that this is because they are also structured inside an unordered list tag (somehow?): <form method="POST"> <label for="id_response_0">Do you like any of these foods? <ul> <li>Pasta</li> <li>Rice</li> <li>Cheese</li> </ul> </label> <ul id="id_response"> <li> <label for="id_response_0"> <input type="radio" name="response" value="1" required="" id="id_response_0"> Yes </label> </li> <li> <label for="id_response_1"> <input type="radio" name="response" value="2" required="" id="id_response_1"> No </label> </li> </ul> <input type="hidden" name="csrfmiddlewaretoken" value="FaOTY4WlVLFMl3gNtut8BJihJKub1Is0wRJRxxLck1e2eJocJVXRiGoOLDr9jdvx"> <input type="submit"> </form> Is there a way I could stop this and just maintain the bullet points on the 'Pasta', 'Rice' and 'Cheese' whilst removing the bullet points/ list from 'Yes' and 'No'? -

Django form : how to get data in a ManyToMany field?
My objective is to implement the same kind of features than in admin panel with a many to many relationship. Everything seem to work all right, but when I submit my form, I get some strange results: I'm probably missing something but I cannot fogure out what goes wrong. For now, when I add lines, everything is OK. Problems occur when I try to remove lines from the group. I'm taking about users, I have a first list of 'all users' and the second one will make a group. When I had a user, then remove another one, the form cannot be validated; the list is empty, the removed user "disappear" (it is not in the group list nor among "all users". If I remove one user, then add a new one, the only user in my form after validation is the one I added, all other ones are removed. I hope I'm clear, many thanks in advance for your advise.

Please give me a hint if you can resolve the problem, thank you! # tasks.py @shared_task(bind=True) def long_time_def(self, *args, **kwargs): tp = ThreadPool(5) tp.set_tasks(pv.check_position_effective, list(args)) res = tp.final_results() while len(res) < len(args): print(res) return 'finished' # ../public/tools.py class ThreadPool: def __init__(self, max_thread_num=5): self.over = False self.results = [] self.func = None self.args_list = None self.task_num = 0 self.max_thread_num = max_thread_num self.pool = ThreadPoolExecutor(max_workers=max_thread_num) self.cond = threading.Condition() def set_tasks(self, func, args_list): self.task_num = len(args_list) self.args_list = args_list self.func = func def get_result(self, future): self.results.append(future.result()) if len(self.args_list): args = self.args_list.pop() task = self.pool.submit(self.func, *args) task.add_done_callback(self.get_result) else: print("result：%s"%self.results) while self.task_num != len(self.results): print(self.results) time.sleep(1) print('\n', 'finish') self.cond.acquire() ############ this place ############ self.cond.notify() ############ this place ############ self.cond.release() return def _start_tasks(self): for i in range(self.max_thread_num): if len(self.args_list): args = self.args_list.pop() task = self.pool.submit(self.func, *args) task.add_done_callback(self.get_result) else: break def final_results(self): self._start_tasks() if self.task_num == len(self.results): return self.results else: # print("main locked") # self.cond.acquire() ############ this place ############ print("main waiting") self.cond.wait() ############ this place ############ # print("main … -
Django application page not showing when deploying to pythonanywhere.com
My application works perfect when run locally on my mac os, but when it is deployed to pythonanywhere (and also on my partners windows os laptop) one of the pages just shows the html code instead of the actual page as shown below: I dont know what the problem is as it runs locally fine.
