Unexpected Django ORM behavior
I have a function, which must make things according to its name, but it works weird for me. def get_or_create_artists_by_metadata(metadata: Dict[str, str]) -> List[Optional[Artist]]: if artists := metadata.get('artist'): artists = parse_artists_from_string(artists) # returns list of strings try: existing = Artist.objects.filter(title__in=artists) # 1 except Exception as err: log.exception('Database error!') log.exception(err) return [] new_artists_list = list(set(artists) - set(itertools.chain(*existing.values_list('title')))) objs = [Artist(title=artist) for artist in new_artists_list] try: new_artists = Artist.objects.bulk_create(objs) # 2 except Exception as err: log.exception('Error during artists creating!') return [*existing] result = [*existing] if new_artists: # 3 result.extend(new_artists) return result else: return [] For instance, I have 2 strings in artists var. On the step 1 I have nothing at first, empty QuerySet. Then on the step 2 I create new artists and at the same time I have some entries in existing var! So on the step 3 I have true, extend result, and there are 4 entries already. Please, explain me this behavior and how should I manipulate this. -

I am unable to start Gunicorn on ec2 for Django
I am currently trying to set up my django website on ec2. If I run gunicorn --bind 0.0.0.0:8000 website.wsgi:application the website runs as long as I specify port 8000 at the end of the URL. I do not want to have to do this so my end goal is to use nginx. I created my gunicorn.service file via the following command: sudo nano /etc/systemd/system/gunicorn.service Its contents are as follows: [Unit] Description=gunicorn daemon After=network.target [Service] User=root Group=www-data WorkingDirectory=home/ubuntu/Fantasy-Fire/website ExecStart=/home/ubuntu/env/bin/gunicorn --access-logfile - --workers 3 --bind unix:/home/ubuntu/Fantasy-Fire/website/website.sock website.wsgi:application [Install] WantedBy=multi-user.target When I run sudo systemctl start gunicorn I get the following error: Failed to start gunicorn.service: Unit gunicorn.service is not loaded properly: Exec format error.

Django how to do a conditional redirect after POST?
I have a form that displays some of the fields in the user profile among other things. In this form the fields from the profile are disabled. If the details are outdated the user can go to the edit profile view and update the details. For this, I included a button in the template of the form. After updating the profile I want the user to return to the form. This last part is the one I am having problems with. The link to edit the profile from the form looks like: <a class="btn btn-outline-info" href="{% url 'profile'%}?next={% url 'submission_resume' %}">Edit Profile</a> This is how the url looks comming from the form: http://127.0.0.1:8000/users/profile/?next=/submissions/resume/ The problem is that in the edit profile view I do not know how to implement the conditional redirect: def profile(request): """ View and edit the profile. It requires user to be login """ if request.method == 'POST': form = UserModifyForm(request.POST, instance=request.user) if form.is_valid(): form.save() messages.success(request, f'Your account has been updated!') #??? if next in url go back to the form ??? #??? return redirect(???) ??? #??? else: ??? return redirect('profile') else: form = UserModifyForm(instance=request.user) #--> Dict for template with the forms context = { 'form': form, … -

How exactly does django 'escape' sql injections with querysets?
After reading a response involving security django provides for sql injections. I am wondering what the docs mean by 'the underlying driver escapes the sql'. Does this mean, for lack of better word, that the 'database driver' checks the view/wherever the queryset is located for characteristics of the query, and denies 'characteristics' of certain queries? I understand that this is kind of 'low-level' discussion, but I'm not understanding how underlying mechanisms are preventing this attack, and appreciate any simplified explaination of what is occuring here.

Unsure of how to manage email configurations
I am attempting to create Reset Password functionality using Djoser. I am successfully hitting my API's auth/users/reset_password/ endpoint, which is then sending an email as expected. But the problem is occurring in the content of the email. It is sending a redirection link to my api, rather than to my frontend. Please note, any <> is simply hiding a variable and is not actually displayed like that Here is an example of what the email looks like: You're receiving this email because you requested a password reset for your user account at <api>. Please go to the following page and choose a new password: <api>/reset-password/confirm/<uid>/<token> Your username, in case you've forgotten: <username> Thanks for using our site! The <api> team The goal with this email is to send the user to the /reset-password/confirm/ url on my frontend, not on my api, which is currently occurring. Here are my DJOSER settings: DJOSER = { 'DOMAIN': '<frontend>', 'SITE_NAME': '<site-name>', 'PASSWORD_RESET_CONFIRM_URL': 'reset-password/confirm/{uid}/{token}', } The expected behavior is for the DOMAIN setting to alter the link that is being placed in the email, but it is not. I can't seem to find reference to this particular problem within the docs. Any help here would … -

Combine views in views.py into a single view?
I am building a project in which I have a couple of views in my views.py that I want to combine in a dashboard format (4 views side by side). They are sufficiently complex because each view takes in a number of variables and has a lot of logic server side, and I also intend to use them elsewhere alone. The question I have is what is the best way to combine separate views from views.py into a single view if I want to create a dashboard view (ie. I have a base template with header/footer, and then 4 views embedded in that base). My proof of concept was to call the view with the right variables and decode the rendered return, then pass it as a variable onto the template, and finally just insert it as safe code. See below. My gut tells me this is terrible practice, but I'm not sure the includes/extends system is appropriate for such a use. views.py def view1(request, r1_level, r2_level, d_level, call_code): ... return render(request, 'modules/logic/levels/' + call_code + '.html', { 'indicators': indicators, 'd_level': d_level, 'prof': prof, 'a_flag': a_flag } ) def dashboard(request, level_code): view1 = view1(request, r1_level, r2_level, d_level, call_code).content.decode("utf-8") ... return … -
Django - 'NoneType' object has no attribute 'year'
So every time I try to view someone's profile when they haven't entered a birth day I get this error 'NoneType' object has no attribute 'year'. I followed this post to add the birthday/age to the user profile so no reason to include my code since I got it from here https://stackoverflow.com/a/39761072/12229283. I tried adding a default to the model but that doesn't seem to work how do I make it so if a user doesn't enter a birthday just skip it and ignore it? Thanks -
Django - @login_required decorator while passing arguments with form POST
I am passing a variable from template to view with form POST method. And view uses @login_required decorator as it is needed. If user is not logged in it goes login page and come backs to the view again but the passed variable information was not there anymore. Is there any way to solve this? I found a old stackoverflow post here but it's not working for me.

Sending data from Django application to another Python script
I have a Django application where some data can be saved on my database using a form. I would like to create a Python script that, as soon as a new record is created, sends that data to an external Python script as json, and this external Python script should perform some operation with this data. This question is not about code, but i'm trying to be as specific as possible: is there a way to create a system that sends data to another system? In this case the data i need to send is the records submitted from forms of my Django app to another Python script. I'm supposing that the external script should be listening to some sort of URL, maybe? How could i accomplish this? Maybe with Webhooks?
