Django not recognize UUID Foreign Key
I had this current model: class Apps(models.Model): """ Apps são os aplicativos que terão financeiro gerido, uma empresa/usuario pode ter multiplos apps conectados """ app_code = models.UUIDField(auto_created=True, default=uuid.uuid4, unique=True, primary_key=True) chave_app = models.UUIDField(auto_created=True, default=uuid.uuid4, unique=True) usuario = models.ForeignKey(Usuario, on_delete=models.CASCADE) descricao = models.CharField(max_length=100) The usuario field is an ForeignKey... The usuario model is this: class Usuario(AbstractBaseUser): """ Classe que ira gerir o cliente final, cadastrado via APP ou Webapp """ user_id = models.UUIDField(auto_created=True, default=uuid.uuid4, unique=True, primary_key=True) nome = models.CharField(max_length=120) celular = models.CharField(max_length=20, unique=False) email = models.EmailField(max_length=100, unique=True) ativo = models.BooleanField(default=True) chave_api = models.UUIDField(auto_created=True, default=uuid.uuid4, unique=True) created_at = models.DateTimeField(auto_now_add=True) objects = AccountManager() USERNAME_FIELD = 'chave_api' REQUIRED_FIELDS = ['email', 'nome', 'celular'] class Meta: ordering = ('-created_at',) All works nice, but when i try to list apps on django-rest-framework as list. I did same way on anothers models, with no foreign key, and listing is all ok. The error is giving only on this view with Foreign Key. TypeError at /apps/ str returned non-string (type UUID) At database, my fields was inserted with this values: [ { "app_code": "423676e9968d41beaeeeb2da43fc56d8", "chave_app": "86c18ae7809e4bda88830090f309a00c", "descricao": "Matrix Cashback 2.0", "usuario_id": "998339b46bde40bca053978670626a6f" } ] I'm using Django-rest-framework and Django in an personal project.

How to order related field by its foreign key fields?
Let's assume I have three model like below; class Stats(models.Model): gp = models.IntegerField(default=0) won = models.IntegerField(default=0) drawn = models.IntegerField(default=0) lose = models.IntegerField(default=0) gf = models.IntegerField(default=0) ga = models.IntegerField(default=0) gd = models.IntegerField(default=0) pts = models.IntegerField(default=0) class Team(models.Model): team_name = models.CharField(max_length=50) stats = models.ForeignKey(Stats) class Group(models.Model): group_name = models.CharField(max_length=1) teams = models.ManyToManyField(Team) And, this is my serializer for Group Model class GroupSerializer(serializers.ModelSerializer): teams = TeamSerializer(read_only=True, many=True) class Meta: model = Group fields = '__all__' However, I want to order the teams according to pts and gd fields of their stats. I tried to add order_with_respect_to='stats' to the Team model and ordering = ['pts', 'gd'] to the Stats Model but it did not work. -

error: Requested setting INSTALL ED_APPS, but settings are not configured.
I installed Django and made a project called joseph. This is all I've done thus far. I can't access it at all, however, because I can only access the core commands. I get this message when I put it django-admin help: Note that only Django core commands are listed as settings are not properly configured (error: Requested setting INSTALL ED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.). I have looked for an answer but all of the other ones seem to be about scenarios not like mine because they already have been able to do things. I haven't been at all. What am I supposed to do here? Thanks. -

Django `loaddata` pretty way to load same objects with different pk (id)
I use loaddata to load my fixtures (Django doc.) For example i have this example.json: [ { "model": "foo.bar", "pk": 1, "fields": { "name": "dmytryi" } }, { "model": "foo.bar", "pk": 2, "fields": { "name": "dmytryi" } }, ... (repeat it until pk is not 10 with increasing pk by one) { "model": "foo.bar", "pk": 10, "fields": { "name": "dmytryi" } }, ] How you see, I have 10 same objects (same name for same model), but with different pk value. After loaddata I will see in my database 10 objects. It is OK. Give a hint how to reduce the code, but leave the same result, if it exists. Thanks you! -

DATA_UPLOAD_MAX_MEMORY_SIZE not working?

Send PIL Image from Django View to Browser for Download via HttpResponse

How to use jQuery datetimepicker plugin with Django
I'm a beginner with Django, working on my first project. For the main functionallity of the site I need to use a datetimepicker. Since it's impossible to use Bootstrap (incompatible with Django 1.11) it looks that the only(?) option which I could handle is this one: jquery datetimepicker plugin.

Django REST Angular $http 403 Status
So I have a very simple API endpoint that is supposed to determine if a user is logged in. I did decide to make it a POST request for the sake of hiding the response from being accessed in the browser class Check(APIView): def post(self, request): print request.user if request.user.is_authenticated(): # a successful response for logged in return Response(status = HTTP_200_OK) # return an error status code for not logged in return Response(status = HTTP_401_UNAUTHORIZED) When logged out, I get AnonymousUser in the console and a 401 status code as expected. However when logged in as a superuser or any other user, I get no print output and a 403 status code. This indicates that for some reason the entire callback is never entered. I've been told that it is an issue of permissions but I have AllowAny enabled. Do you guys have any ideas?

What is a good way to push notifications from the server in django?
I was wondering what could be a good way to push notifications of changes from the server in a django app. For example, let's say I have a model called "Transaction". I have several tabs (or even browsers) open, showing a list of "Transactions" objects, and I add a new transaction to the database. I'd like all the tabs to update their content to reflect the change. I can keep an history and poll regularly, but this doesn't scale well for sure. I've read some answer to similar questions on stackoverflow, but they are 6-7 years old, so I was wondering if there were developments on this side. Specifically, I'd like to know: What is the state of the art method to deal with server notifications Is it a good or a bad idea to use a client-side solution like intercom.js and why? I've (quickly) read about websockets, long polling, html5 server-sent events, but I find a little confusing understanding pros/cons and in general understand the related challenges and solutions. Any tips or source where to start? Any suggestions about modules/libraries for a quick implementation? Thanks in advance -

how to run .py script with user input as parameters
I have a .py file, say 'car.py'. It takes 3 inputs (color, make, year). It takes the user input and reads a file, then it returns all matching instances of the color, make, and year given in the input. This script runs fine. Now, I would like to create a web page that works like a search page. It asks for 3 inputs, searches the file (locally) and returns the results. I am using Django for the first time and I am having difficulty figuring out how to call the car.py file and have it run on the background before it returns the result. I have an html interface made but I know I cant ref a python script in it. Is there anything similar in Django? Where I can reference a script and when a button is pressed, it'd run that script given the user input? I don't expect a full coded response, I just want a clarification or reference to an answer. I haven't been able to find anything similar online. -
VS2017 Django Web Project build fails without bin folder
I have created a Django Web Project in Visual Studio 2017 and i have tried serving static files from a directory defined in STATICFILES_DIRS in settings.py. settings.py: STATICFILES_DIRS = ( os.path.join( BASE_DIR, 'static', ), ) Once i had this in settings.py my project didn't build anymore. After quite some time battling with the IDE (i had no errors, it just failed to build and it gave no reason why) i figured out that if i copy the bin folder from a hobby project i made some time ago with PTVS and VS 2015, my project builds fine. And I have absolutely no idea why. The contents of the bin folder are two files: Microsoft.PythonTools.WebRole.dll and wfastcgi.py. I don't have the PC with VS 2015 anymore so i can't check my IDE settings there and i am pretty sure i didn't make any changes nor have i had trouble with settings.py or serving static files in that project. Can anyone explain why this could be happening? Why is VS 2017 not creating a bin folder but VS 2015 did. Is there something i am missing? Using: VS2017 Professional with Python development installed with VS installer - pretty much default settings -
Django 'next' redirect for log in and new user
I have an e-commerce website where users can view ads without logging in. However when they want to post an ad they are re-directed to the login page, where after successful login they are directed to the 'create ad' page. This functionality is working fine. The problem is when user is re-directed to log in page, and she clicks on 'new user' and creates an account, she is not redirected to the 'create ad' page after successful account creation. My code looks like this so far: login.html: #login form <form method="post" action="{% url 'login' %}"> {% csrf_token %} {% if request.GET.next %} <input type="hidden" name="next" value={{ request.GET.next }} /> {% endif %} <b>Name:</b> {{ form.username }} <b>Password:</b> {{ form.password }} <input type="submit" value="OK"> </form> # button to redirect to new account creation page <a href="{% url 'unauth_home_new' %}#section0"><button>New Account</button></a> </div> views.py: def login(request, lang=None, *args,**kwargs): if request.user.is_authenticated(): if 'next' in request.POST: return redirect(request.POST['next']) return redirect("home") else: if request.method == 'POST': if lang == 'ur': return log_me_in(request=request,template_name='login_ur.html') else: return log_me_in(request=request,template_name='login.html') else: if lang == 'ur': return log_me_in(request=request,template_name='login_ur.html') else: return log_me_in(request=request,template_name='login.html')
