Expecting property name enclosed in double quotes: line 1 column 2 (char 1) when converting Stringify to JSON [closed]

Deploying a dockerized Django app on a NAS
I’m very new to Docker and trying to run a simple Django app on my Asustor NAS following this guide https://docs.docker.com/samples/django/. But I can’t figure out what should I do with the ports to access the app. The NAS is connected to the Internet via a router. Apache web server is running on port 80 on the NAS. There also is a virtual host which already hosts 2 Wordpress websites. Example1.com redirects to /Web/example1 and example2.com redirects to /Web/example2. I also have an example3.com domain, which redirects to /Web/example3. So, I upload my app to /Web/example3 and start it with "docker-compose up". It starts successfully and the containers appear in Portainer in the NAS admin panel. Docker-compose.yml command is “python manage.py runserver 0.0.0.0:9000”. I tried setting ports in docker-compose.yml to “9000:9000” and “9000:80”. In both cases accessing NAS-local-ip:9000 returns the "server isn’t responding" error. Example3.com displays Apache “Index of/“ page with a list of files and folders of my app. How should I configure the ports to access the app both within the local network and outside of it? Any help will be appreciated. -

Django - forloop to show/filter a value to show only once the entrys
I have a model (Restrictie) in which those who voted (participanti) and those who voted (votant) are registered. If I forloop in the templates, I can see who voted for whom, but one line is displayed for each record. How can I make a forloop or query in which participants are displayed only once and next to all the voters for example: name participanti - (name votant 1, name votant 2, ....) Below my code models.py class Participanti(models.Model): campanievot = models.ForeignKey(Campanie, on_delete=models.CASCADE) nume_participant = models.CharField(max_length=200, verbose_name='nume') dep_participant = models.CharField(max_length=200, verbose_name='departament') votes = models.IntegerField(default=0) def __str__(self): return self.nume_participant class Meta: verbose_name = 'Participanti' verbose_name_plural = 'Participanti' class Restrictie(models.Model): participanti = models.ForeignKey(Participanti,on_delete=models.CASCADE, verbose_name='Votat') votant = models.ForeignKey(UserVot,on_delete=models.CASCADE) def __str__(self): return str(self.participanti) class Meta: verbose_name = 'Voturi efectuate' verbose_name_plural = 'Voturi efectuate' views.py def rezultate(request): cineavotat = Restrictie.objects.all() ....... I tried this but it's show all entries like : name 1 = voters 1, name 1 = voters 2 ... {% for p in cineavotat %} {{ p.participanti }} - {{ p.votant}} {% endfor %} Please help me with a solution. Thank you! -
multiple deletion in django rest framework

Danger of DEBUG = True in production [closed]
I've read all about Django's DEBUG = True and some of the effects, but it never states WHY you should not use DEBUG = True in production, only that you shouldn't. I've also read that DEBUG=True remembers every query you make which will increase in memory over time. Recently though, I've found out you can just change the technical_500.html, technical_404.html (and maybe even the technical_500.txt) in .venv/Lib/site-packages/django/views/templates or the functions themselves in .venv/Lib/site-packages/django/core/handlers/exception.py and get no traceback and data dump whenever you get a 404 or 500 response. So my question is: is there any real danger in setting DEBUG to True and changing the html's (or functions) mentioned above, if you also have no queries? P.S I know this may be bad practice, just curious. -

Which one is better option to choose as a Primary key for Cart in Django? UUID or Session Key?
So, I have been working on a DRF eCommerce project. As, using the auto incrementing id field in the cart model isn't ideal. I chose to use UUIDField for it. I can achieve the same with session key too. But, I was wondering if there is any approach that meets the industry standard? Please suggest me the more appropriate primary key choice with a explanation from a industry point of view. class Cart(models.Model): id = models.UUIDField(primary_key=True, default=uuid4) skey = models.CharField(max_length=250, null=True) total_price = models.PositiveIntegerField(editable=False, blank=True, null=True) date_added = models.DateField(auto_now_add=True) def __str__(self): return self.skey -
