Is there a way to debug Django urls?
I have a problem with Django urls that I cannot get to the bottom of. I have tried the recommendations given in the answers to this question, but they don't help. <project>/urls.py urlpatterns = [ ... path('duo/', include('duo.urls')), path('users/', include('users.urls')), ] duo/urls.py urlpatterns = [ ... path('', include('users.urls')), ... ] users/urls.py urlpatterns = [ path('', views.SelectPartner.as_view(), name='select-partner'), ... ] when I use the url http://192.168.1.138:8000/duo/ I get taken to the page http://192.168.1.138:8000/accounts/login/?next=/duo/ which does not exist. I cannot think what is going on here because the word accounts does not exist anywhere in the project Is there some tool that I can use to find out what is happening? -

Deployed Django App Not Working On Ubuntu NGinx/Gunicorn
When following this tutorial (https://rahmonov.me/posts/run-a-django-app-with-gunicorn-in-ubuntu-16-04/), everything worked for a basic website. This at least proves the firewall rules are working as expected. However, when deploying my Django web app, I'm simply receiving the message: "This site can't be reached." I've checked the Nginx error and access logs, and they don't contain anything since the 13th August when I last looked into this issue, and when the website repeatedly gave me errors about missing modules that have since been installed. Is there anywhere else I can check to see why the Django app now isn't loading via the web page? Just for peace of mind, below are all my config details. /etc/nginx/sites-available/terraformdeploy: server { listen 8000; server_name 0.0.0.0; location = /favicon.ico { access_log off; log_not_found off; } location /static/ { root /opt/envs/terraformdeploy; } location / { include proxy_params; proxy_pass http://unix:/opt/envs/terraformdeploy/terraformdeploy.sock; } } I've run: sudo ln -s /etc/nginx/sites-available/terraformdeploy /etc/nginx/sites-enabled sudo nginx -t returns: nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful service nginx status returns: nginx.service - A high performance web server and a reverse proxy server Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled) Drop-In: /etc/systemd/system/nginx.service.d └─override.conf Active: active (running) since Thu 2020-08-13 15:44:44 … -
How to remove pre-populated extra forms from django admin inlines
for example, suppose I have these two models: class Comment(models.Model): content = models.TextField() post = models.ForeignKey('Post', on_delete=models.CASCADE) class Post(models.Model): content = models.TextField() and I have set Comment as Inline for Post admin, like: class CommentInline(admin.StackedInline): model = Comment extra = 3 @admin.register(Post) class PostAdmin(admin.ModelAdmin): inlines = [CommentInline] Now, I want to set initial values into the extra 3 forms of comment inlines. and I have accomplished that by CommentInline's get_formset method like: def get_formset(self, request, obj=None, **kwargs): # this list will be generated dynamically initial = [ {"content": "dynamic data 1"}, {"content": "dynamic data 2"}, {"content": "dynamic data 3"} ] formset = super().get_formset(request, obj, **kwargs) formset.__init__ = curry(formset.__init__, initial=initial) # from django.utils.functional import curry return formset now inline forms are populating by dynamic data as expected. but the problem is there are no buttons for removing the form. I can add new comments, edit initial comment, but I can't delete any comment from those pre-populated comments! my questions are: How can I remove extra inline form before saving into DB? Is my approach is ok for populating initial values? -

Setting time field in django such that the stored time cannot be changed later
I have a orders model which looks like this: class Order(models.Model): customer=models.ForeignKey(Customer,on_delete=models.SET_NULL,null=True,blank=True) date_ordered=models.DateTimeField(auto_now=True) complete=models.BooleanField(default=False,null=True,blank=False) and this is a specific view from my views.py: def handlerequest(request, id): order=Order.objects.get(id=id) items=order.orderitem_set.all() verify = Checksum.verify_checksum(response_dict, MERCHANT_KEY, checksum) PaytmHistory.objects.create(**response_dict) if verify: if response_dict['RESPCODE'] == '01': order.transaction_id=transaction_id order.complete=True order.save() print('order successful') Now what is happening is that whenever this is view is called the order is saved and the time updates to when the order was saved. But in future when I manually make some changes to the fields like when I update the shipping status of the order and save it then the time updates which I dont want . So is there any fix to this such that after order.complete=True order.save() The time cannot be changed -
Do I need to write the full media path in Django?
I am trying to download a file that is stored in the media folder and it seems as it only works when I am writing the full path as: file_location = '/home/user/user.pythonanywhere.com/media/' In the settings page on pythonanywhere, the 'media url' points to the same directory. So I don't really understand why I just can't write /media/ instead for the full path. Has it something to do with my settings.py file? I have these lines there: MEDIA_ROOT= os.path.join(BASE_DIR, 'media') MEDIA_URL="/media/" Do I need to have these lines at all? -

Django Filter in View or HTML
I am working on a basic assignments project where the teachers can add assignments and the students can submit the answers. I have saved it with models Assignments and Submissions as shown in the code below. The thing I am trying to do is that I want to show different buttons with different links when a parent has submitted the assignments. To be exact I want to show "Add submission" if a parent has not submitted and "Update Submission" when he/she has submitted already to a particular assignment. The problem I am having is that when a parent submits to a certain assignment then other parents also see "Update Assignment" if I give some filtering on the querysets. How can this be handled? Is there something we can do in html or some other filtering in views.py? Or I have to change by style of doing this. Please your support will be a great help.

Django traceback errors
I am a beginner in python, pycharm and Linux, I want to open an existing Django project. But when I use "python manage.py runserver", I am getting a series of trace-back errors which I am attaching below. I have installed all the LAMP stack i.e., Linux OS, Apache2 Web server,MariaDB and MYSQLclient with latest versions and have also tried updating the versions in requirements.txt. However, I haven't installed PhpMyAdmin yet, for time basis I would want to just use terminal for viewing my data tables. Could you please explain me about the tracebacks and what can I do to run the program. It would be of great support if you can provide me with a solution. Thank you. Keep safe and kind regards, SD.
