How to get the value of a model form and assign it to its key in another model form
Suppose I have three models A, B, and C. I also created two model forms from these models. I want to know that is there a way to get the value of the B model form and assign it to its key in the c model form in views? class A(models.Model): name = models.CharField(max_length=200) class B(models.Model): name = models.CharField(max_length=200) class C(models.Model): a= models.ForeignKey(A, on_delete=models.CASCADE) b= models.ForeignKey(B, on_delete=models.CASCADE) answer = models.SmallIntegerField(choices=RATING_CHOICES) class BForm(ModelForm): class Meta: CHOICES = B.objects.all() model = B fields = ('name',) widgets = {'name': Select(choices=( (x.id, x.name) for x in CHOICES ))} class CForm(ModelForm): class Meta: model = C fields = ('answer',) widgets = { 'answer': RadioSelect(choices=RATING_CHOICES),} def index(request): a1 = A.objects.get(id=1) a2 = A.objects.get(id=2) if request.method == "POST": b_form = BForm(request.POST) form = CForm(request.POST, prefix='a1') form1 = CForm(request.POST, prefix='a2') if (form.is_valid and form1.is_valid()): b_form.save() z = form.save(commit=False) z.a= a1 z.b = # I could not figure out this z.save() z = form1.save(commit=False) z.a = a2 z.b = # I could not figure out this z.save() -

Playback state control of spotify web player sdk using spotify api
I am creating a webapp using django and react in which multiple user can control playback of a spotify player (play/pause, skip). This is useful in case of a house party or something where people are listening to a common device . I am thinking if i can integrate the spotify web player sdk and all users can listen to synced playback and control at the sametime remotely. I understand single spotify account needs to register that webapp to be used as device. My question is if can i control the state of playback if the page is opened by multiple users so that they listen to a song synchronously. -

Python crash course chapter 18. No learning_log directory is created
I'm doing exercises in the 'Python Crash Course' book in Chapter 18. I can't create the learning_log directory and manage.py, init.py, settings.py, urls.py, wsgi.py files. I made the creation of a virtual environment with the command: python -m venv ll_env I am using Windows so I used the command to activate the virtual environment: ll_env\Scripts\activate The environment has been activated because the name (ll_env) is displayed before the prompt. Then I installed the Django framework with the command: pip install django Installed successfully.But when I used the command: django-admin.py startproject learning_log . Unfortunately, the learning_log directory and the previously mentioned files are not created. I installed django version 3.1.4 and the book is version 2.2. Is there a problem here? Is there any other command to create this directory and files? Let me add that I was doing it all in the PyCharm terminal. -

Django DB cyclic model prevention Queryset
I am working on a project where I need have cyclic entries. Think, a recipe might have a sub recipe and that might have a sub recipe. The issue is one of those sub recipes might have its parents' parent as a child. So I am trying to prevent this or at least not wanting to have to proved the user with an option to select that item. To do this. I wanted to check on the server side if there is cycle. A classic loop detection. So I was going to either implement BFS or DFS, possible DFS to minimize the memory usage and check each child and their child and so forth until I visit all nodes and keep a visited dict to keep the ids of all the models entries I see. The issue is queryset is not providing some of the basic functions to do pop and push. I can convert the query set to list but that could be expensive and run out of memory. It is unlikely to have 100000 depth recipe but in theory it can happen. Is there an alternative to this? I was thinking maybe pass the visited list to filter … -
How many Django models is appropriate?
I'm making a Django project from a pre-existing epidemiological Excel model and I'm not familiar with how best to make use of Django models. The examples in the tutorial seem to fit 'just right' (e.g. one object is obviously the parent of another), and my data does not. My data consists of the following: A country, which has a name, a population of males and a population of females. However the population depends on the year (2019 to 2030). A cancer, which has a type (e.g. Breast cancer), a set of stages (e.g. Stage IV breast cancer). Cancer types interact with countries. E.g. the likelihood of dying from Stage III lung cancer is different in Australia than Uganda. This data currently lives in a bunch of json files, one which has the population per year of countries, one which has the proportion of people in an age group for a country, one which has the likelihood of dying from a cancer etc. I created these json files by exporting them from pandas dataframes, which we took from the lookup tables in Excel. I presume I could import each of these json files as its own model, but I get the … -

How can I enable users to select their workspace when using Sign in with Slack?
I'm having some trouble with getting Sign in with Slack to work like I want it to. Specifically, I'm seeking to build a platform that people can use for their Slack workspaces, and depending on which workspace they are signing into, different content (in this case, saved slack posts) show up.

Django Rest Framework - "unique_together" internal server error. How to respond with error
I currently have a model called "Review" where I have a "unique_together" constraint so one user can only write one review per post. class Review(models.Model): created = models.DateTimeField(auto_now_add=True) user = models.ForeignKey(User, related_name='reviews', on_delete=models.SET_NULL, null=True) post = models.ForeignKey(Post, related_name='reviews', on_delete=models.CASCADE) rating = models.IntegerField() comment = models.TextField(blank=True, null=True) class Meta: unique_together = ['user', 'post'] And in my View I am grabbing the user from the request (I'm using token authentication) and use that user to save the object by overwriting the "perform_create" method: class ReviewCreateView(CreateAPIView): permission_classes = [IsAuthenticated] serializer_class = ReviewCreateSerializer def perform_create(self, serializer): serializer.save(user=self.request.user) And my serializer looks like this: class ReviewCreateSerializer(ModelSerializer): class Meta: model = Review fields = ['post', 'rating', 'comment'] When I try to submit two reviews to the same post by the same user I get an internal server error. The body of my HTTP POST request looks like this: { "post" : 11, "rating": 1, "comment": "this is a great post" } Instead of getting an error response (for example 403 error). I get this Django server error instead: django.db.utils.IntegrityError: duplicate key value violates unique constraint After spending some time researching I saw that Django Rest Framework provides the "UniqueTogetherValidator".
