Django Nested Serializers won't work independently- Key Error /dashboard/api/institution/editor/ 'id'
I'm trying to create an app using JQuery Datatables Editor and a Django REST framework API. Whenever I try to create an entry, I am returned the above key error. I believe the problem is traced back to the to_internal_value function within the InstitutionDatatableSerializer. However, I cannot delete this function as it is necessary for me to create a new entry for the InvestigatorDatatableSerializer. How can I fix the serializer? serializers.py class InstitutionDatatableSerializer(serializers.ModelSerializer): id = serializers.IntegerField(read_only=True) def to_internal_value(self, data): return get_object_or_404(Institution, pk=data['id']) class Meta: model = Institution fields = ('__all__') datatables_always_serialize = ('id',) class InvestigatorDatatableSerializer(serializers.ModelSerializer): institution_name = serializers.ReadOnlyField(source='institution.name') institution = InstitutionSerializer() class Meta: model = Investigator fields = ('id', 'last_name', 'first_name', 'email', 'institution_name', 'institution', ) datatables_always_serialize = ('id',) models.py class Institution(models.Model): id = models.AutoField(unique=True, primary_key=True) name = models.CharField(max_length=50) dept = models.CharField(max_length=50) class Meta: managed = True db_table = 'institution' def __str__(self): return str(self.name) class Investigator(models.Model): id = models.AutoField(unique=True, primary_key=True) last_name = models.CharField(max_length=50) first_name = models.CharField(max_length=50) email = models.CharField(max_length=50) created_at = models.DateTimeField(auto_now_add=True) institution = models.ForeignKey(Institution, models.DO_NOTHING, related_name='institution_id', ) class Meta: managed = True db_table = 'investigator' def __str__(self): return str(self.last_name) -

How to configure nginx to serve Django at a different endpoint?
I separated my frontend (NextJS) and my backend (Django). I want to serve my Django app at /api using Nginx. events {} http { server { listen 80; gzip on; server_name $HOST; location /api/ { proxy_pass http://backend:8000/; proxy_set_header Host $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; } location / { proxy_pass http://frontend:3000/; } } } where backend and frontend are corresponding docker-compose services. Django is not recognizing my configuration and is having a lot of issues. For example when I access /api/admin it redirects to /admin and causes troubles. I searched around but can't find any answers. How can I solve this? -
Making a file available at url using uWSGI, Django and nginx
I'm attempting to have Django/nginx serve a specific file under a specific URL, unrelated to the Django app itself. I have a .php file I'd like to serve and be displayed as a normal PHP. The PHP file I'm using: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>PHP - Hello, World!</title> </head> <body> <h1><?php echo 'Hello, World!'; ?></h1> </body> </html> I tried adding this to my nginx configuration to achieve it: location /deploy { alias /var/www/deploy.php } When I then attempted to run my uWSGI app, going to that URL (example.com/deploy) does indeed redirect to deploy.php, but I get a pop-up to save the file on my PC (download) instead of it being displayed as a webpage. I'm not sure how to configure it to behave correctly, I'm working with nginx for the first time. -
Django GeometryDistance usage with postgis database
I am having some issues using GeometryDistance where I have a node point object and am trying to find the closest node in another table in the database. GeometryDistance(start_node.geom, vertex.objects.all()) This is the truncated output. GeometryDistance(Value(<Point object at 0x7f3afe8e4d90>) <-> <QuerySet [<WaysVerticesPgr: WaysVerticesPgr object (1)>, <WaysVerticesPgr: WaysVerticesPgr object (2)>, <WaysVerticesPgr: WaysVerticesPgr object (3)>, and the only reference info I can find is this from Django. I know the issue is with the WaysVerticesPgr queryset in the second position but don't know how to only get the geometry from the table. I would like to return the closest nodes in the vertex table to the start_node. the vertex table has the geometry in column 'the_geom'. vertex.objects.order_by(GeometryDistance(start_node.geom, vertex.objects.all().the_geom)) Here, the queryset doesn't have the_geom attribute. I remember reading that django doesn't evaluate querysets until it has to either through iteration or other methods but I don't know exactly how I should go about this query. Any help is appreciated. -
Django: Model attribute looks for field works in view, but not in template
Say I have a model: from django.db import models class Foo(models.Model) fav_color = models.CharField(max_length=250, help_text="What's your fav color?") print(Foo.fav_color.field.help_text) # prints: What's your fav color? Say I have a view with context: { 'Foo': Foo } And in a template {{ Foo.fav_color.field.help_text }}, the result will be blank. However {{ Foo }} will print the string representation of the model, so I know the models is getting passed into the template. Why are the attributes look ups to get the help_text failing in the template, why is the help_text empty in the template? -
