How can I fill the table correct in Django template?
I want to fill the table in a correct way (see the picture). But I can't do it without changing a model or using tables2 app. How I can go through Teams and get 1 player for each team and then go next line for a table? What I have now: Correct and wrong tables models.py: from django.db import models class Server(models.Model): name = models.CharField(max_length=16) url = models.CharField(max_length=64) class Team(models.Model): server = models.ForeignKey(Server, on_delete=models.CASCADE) name = models.CharField(max_length=16) n_players = models.IntegerField(null=True) class Player(models.Model): server = models.ForeignKey(Server, on_delete=models.CASCADE) team = models.ForeignKey(Team, on_delete=models.CASCADE) name = models.CharField(max_length=16, null=True) highlight = models.BooleanField(default=False) views.py: from django.shortcuts import render from .models import Server, Team def index(request): server_list = Server.objects.order_by('name')[:3] context = {'server_list': server_list} return render(request, 'monitor/index.html', context) templates index.html: {% for server in server_list %} <h2>{{ server.name }}</h2> <table> <tr> {% for team in server.team_set.all %} <th> <b>{{ team }}</b> </th> {% endfor %} </tr> {% for team in server.team_set.all %} <tr> {% for player in team.player_set.all %} <td>{{ player }}</td> {% endfor %} </tr> {% endfor %} </table> {% endfor %} -
Django DecimalField returns strings
I have this model: class Item(models.Model): amount = models.DecimalField(max_digits=15, decimal_places=2) quantity = models.DecimalField(max_digits=15, decimal_places=6) total = models.DecimalField(max_digits=15, decimal_places=2) def save(self, *args, **kwargs): ## Following lines are for debugging only print(self.amount) print(self.quantity) print(type(self.amount)) print(type(self.quantity)) self.total = self.amount*self.quantity super(Item, self).save(*args, **kwargs) What I"m trying to do here is to automatically calculate and save the total value (quantity*amount). This is something I need to have available as a field but it should be calculated automatically. However, I get this error: can't multiply sequence by non-int of type 'str' When I look at the print() and print(type()) results... I see that indeed, these fields are strings even though they contain the numbers I expect: 982.00 0.008300 <class 'str'> <class 'str'> Why does this happen? -

How To Change Default Fields In Django Login Form
As we know that the default Django login page form fields are the username and the password, however, I wanted to change the login fields to Email and Password, as I think that it's easy for people to login with their email than their username. And Also because the web app I'm trying to create doesn't need a username field. So, How Can I Change the fields to Email And Password? I used this code to change the fields in the Forms.py: from django import forms from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm class UserRegistrationForm(UserCreationForm): email = forms.EmailField() class Meta: model = User fields = ['email', 'password1', 'password2'] Views.py: from django.shortcuts import render, redirect from .forms import UserRegistrationForm def register(request): if request.method == 'POST': form = UserRegistrationForm(request.POST) if form.is_valid(): form.save() return redirect('login') else: form = UserRegistrationForm() return render(request, 'users/register.html', {'form': form}) Any Help Would Be Appreciated! -

Insert foreighn data inside RAW SQL statement in migration file in Django
Question is regarding custom migration file. from django.db import migrations from django.contrib.contenttypes.models import ContentType class Migration(migrations.Migration): dependencies = [ ('api', '0007_auto_20191013_1553'), ] try: con = ContentType.objects.get_by_natural_key(app_label='api', model='product') model = ContentType.model_class(con) db_table = model._meta.db_table operations = [ migrations.RunSQL( """ DROP TRIGGER IF EXISTS text_searchable_update ON %(db_table)s; """, {'db_table': db_table} ), migrations.RunSQL( """ CREATE TRIGGER text_searchable_update BEFORE INSERT OR UPDATE ON %(db_table)s FOR EACH ROW EXECUTE FUNCTION tsvector_update_trigger(textsearchable_index_col, 'pg_catalog.english', description) """, {'db_table': db_table} ) ] except ContentType.DoesNotExist: operations = [] Goal of this migration is to create trigger on db column textsearchable_index_col to update stored vector in case description column is created or updated. Problem is I want to make sure that trigger is created on proper table in case of db_table name would get changed. So that I get db_table = model._meta.db_table and I want to insert db_table value in the raw SQL statement, but seem like I dont know how to do it. In the example in Django docs they use %s formattig but it raises SQL syntax error during migration process. Question is how to insert db_table or any foreign data in wide sense inside this SQL command. Thanks -
Setup for Cookiecutter Django App to serve static files with S3 is not working
I am running a cookiecutter django app and want to use AWS S3 to store my static files. I configured a bucket with policies and have my static files in there. I am struggling with the correct django settings though which look like this right now: DEFAULT_FILE_STORAGE = "storages.backends.s3boto3.S3Boto3Storage" STATICFILES_STORAGE = "storages.backends.s3boto3.S3Boto3Storage" AWS_ACCESS_KEY_ID = "mykey" AWS_SECRET_ACCESS_KEY = "mysecretkey" AWS_STORAGE_BUCKET_NAME = "mybucketname" AWS_QUERYSTRING_AUTH = False AWS_S3_CUSTOM_DOMAIN = "foldername" + '.s3.amazonaws.com' # Static media settings STATIC_URL = 'https://' + AWS_STORAGE_BUCKET_NAME + '.s3.amazonaws.com/' #MEDIA_URL = STATIC_URL + 'media/' STATIC_ROOT = 'staticfiles' ADMIN_MEDIA_PREFIX = STATIC_URL + 'admin/' STATICFILES_FINDERS = ( 'django.contrib.staticfiles.finders.FileSystemFinder', 'django.contrib.staticfiles.finders.AppDirectoriesFinder', ) AWS_DEFAULT_ACL = None I had to uncomment MEDIA_URL = STATIC_URL + 'media/' because if I leave it, it tells me runserver can't serve media if MEDIA_URL is within STATIC_URL. Also in my urls I had to change + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) with static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) at the end of my url patterns. I assume that given the correct settings, django should just enter the static folder that is on AWS and follow the paths from there correct? Now, whenever I run my server locally the static files are not served. My css and my logos are not appearing. Is there something I am … -
How to group URIs using drf-yasg generator?
Some time ago I was using django-rest-swagger (which is no longer maintained) as documentation generator for my API, and one particular thing was very handy: it automatically grouped related URI's by their path. Recently I switched to drf-yasg, which clearly is more advanced and powerfull than its predecessor, although I cannot understand how to group URIs. I have rather vast list of endpoints for mobile client, web, bots and several other things so grouping is crucial for developer to find their way around all available endpoints. For example before switching to drf-yasg this list of endpoints was very beutifully grouped together under single collapsible menu: ... path( 'reservations/', views.ReservationViewSet.as_view({'get': 'list', 'post': 'create'}), name='list-reservations' ), path( 'reservations/<uuid:pk>/', views.ReservationViewSet.as_view({'get': 'retrieve', 'patch': 'partial_update'}), name='retrieve-reservation' ), path( 'reservations/<uuid:pk>/confirm', views.ReservationStatusViewSet.as_view({'put': 'confirm'}), name='confirm-reservation' ), path( 'reservations/<uuid:pk>/decline', views.ReservationStatusViewSet.as_view({'put': 'decline'}), name='decline-reservation' ), path( 'reservations/<uuid:pk>/check-in', views.ReservationStatusViewSet.as_view({'put': 'check_in'}), name='check-in-reservation' ), path( 'reservations/<uuid:pk>/no-show', views.ReservationStatusViewSet.as_view({'put': 'no_show'}), name='no-show-reservation' ), path( 'reservations/<uuid:pk>/cancel', views.ReservationStatusViewSet.as_view({'put': 'cancel'}), name='cancel-reservation' ), path( 'reservations/<uuid:pk>/revert', views.ReservationStatusViewSet.as_view({'put': 'revert'}), name='revert-reservation' ), ... Yet now for whatever reason it's just being thown as plain list together with all other endpoints so it became bery difficult to quickly find and distinguish relevant endpoints (as you see there are multiple groups of endpoints that logically should … -

How to log data to database in Django without html redirect
I have been attempting a difficult task with django and I am curious if I am thinking about the nature of the beast in the correct way, and if so if anybody could provide guidance in understanding how to achieve the goal I am hoping to accomplish. I am attempting to create a webapp that can log information without redirecting the url. I have created a small django project which demonstrates a similar task in a much simpler way. Here is the html page that is included in the http reponse to loading the index page. <p>The purpose of this is to log moments we like in the video</p> {% load static %} <video id="myVideo" width="320" height="240" controls> <source src={% static some/static/movie/path.mp4 %} type="video/mp4"> Your browser does not support the video tag. </video> <button onclick="getTime('goodMoment')">Click Here to Mark Time of awesome moment</button> <p id = "goodMoment"></p> <p> Now I would like to log the string that was posted to "goodMoment" as the "time_string" field for a new instance of the model "SavedTime"</p> <p> however, it is important that there is no http response to take us away from this page, because the video needs to continue playing</p> {% load static … -
recommendation required for buidling a new app
I am very new to programming and am after some advice. At work, we run a soccer score predictor whereby each person enters a score for all the games and gets 3 points for a correct score and 1 point if they get the result correct but not the score. It is a very manual process of inputting scores into Excel and getting results, so I want to build an app. I've done a small amount of work with Django and Python in the past. Does anyone care to recommend a language that would be best suited for this task? Thanks -
Docker run /build in CI with different settings file for test stage
I had gitlab-ci.yml that runs postgres container and then builds a web container. The web container has setting.py with DATABASES setup. .gitlab-ci.yml : ... test: stage: test script: - docker run --name db -d postgres:9.6 - docker build --pull -t test_image . - docker run --name myweb ...blah-blah ... setting.py .... DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'dbname', 'USER': 'dbuser', 'PASSWORD': 'dbpassword', 'HOST': 'db', 'PORT': '5432', #or nothing, worked either way } } .... All that worked fine until some recent changes. The changes were: DATABASE section was moved out of settings.py into postgres.py (in the same directory withg settings.py) with hard-coded values replaced with os.environ.get('SOME VAR') calls and settings.py is now imported into postgres.py: postgres.py from <mywebapp>.settings.settings import * DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': os.environ.get('DB_NAME', ''), 'USER': os.environ.get('DB_USER', ''), 'PASSWORD': os.environ.get('DB_PASS', ''), 'HOST': os.environ.get('DB_HOST', ''), 'PORT': '5432', } } Obviously, that does not agree with the docker which now can not find any of the DB config vars ('ENGINE', 'NAME', etc) and I got to fix it. The error is relatively descriptive (from - docker build --pull -t test_image ., not from "- docker run ..."): django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured.

How to change the queryset returned based on the URL
I am trying to make an educational site and have made a category system. There is a URL for each category and I need change the queryset returned based on the URL I am on.

Adding data to queryset in ModelViewSet
My ViewSet has two methods implemented: list() and get_queryset(). queryset operates on all objects of a model. It's used for filtering data without usage of DjangoFilterBackend. I'm interested in adding an extra field to the response when specific quantity of records is returned, e.g.: if len(queryset) > 1: resp = {"message": "Narrow down filter criteria."} elif len(queryset) == 0: resp = {"message": "No results found."} else: resp = {"message": "OK"} When I run the code, prints placed in list() and get_queryset() appear in the following order: 'list()' checking in... 'get_queryset() checking in... It seems that all changes applied in list() method are overwritten by get_queryset(). Otherwise, this answer would have helped. Is there any other way to return the queryset enriched by additional data, resp in this case? -

Python Django ListView not calling get_queryset
Our group is trying to use the listview class to display all of the posts in a list format to the user in a news feed style. We created the ListView class with a valid 'template_name' and 'context_object_name'. Then, we implemented the get queryset to retrieve all of the posts from the db ('all()' method): class PostsView(generic.ListView): template_name = 'home.html' context_object_name = 'all_posts_list' def get_queryset(self): return Post.objects.all() However, this get_queryset method is not being run when we call the view. When I have built other apps in the past, the get_queryset was called automatically for my ListView objects, as it should according to the ListView documentation. Does anyone have any suggestions? -

How to implement JWT auth in Django with custom endpoint?
