I tried using Django a bit. Now I'm stuck with posting issues in the category. I want to know how we can use it. Are there any filters that I should use?

Changing default value of cell using DJango and SQlite3
I have a problem, I am doing project in Django for my University, and I don't know how can I change value of cell in Database using views.py. My application is an application to do exams online and problem is that many users need to use it at the same time, so I need to do relations in database, like every question has an answer and that answer is provided by one user. And there is problem, I don't know how can I change this dynamically in Views.py. This is my code from Views.py: if form.is_valid(): if username == Users.objects.latest('name'): Choice.objects.username = Users.objects.get('name') And my models.py: class Answers(models.Model): question = models.ForeignKey(Questions, on_delete=models.CASCADE) text = models.TextField() def __str__(self): return self.text class Users(models.Model): name = models.CharField(max_length=30) pass = models.CharField(max_length=30) def __str__(self): return self.name class Choice(models.Model): username = models.ForeignKey(Users, null=True, on_delete=models.CASCADE) question = models.ForeignKey(Questions, null=True, on_delete=models.CASCADE) answer = models.CharField(null=True,max_length=50) class Questions(models.Model): text = models.CharField(max_length=150) madeBy = models.ForeignKey(User, null=True, blank=False, default='kacper', on_delete=models.CASCADE) def __str__(self): return self.text Also if you have any other idea how could I improve this would be great, it's first time that I'm doing something in DJango. -
Multiple plots on same chart with Django and chart.js results in points only (no line)
I'm currently trying to visualize my data which is stored in a MySQL database using Django combined with Chart.js. I have already managed to find a way to retrieve data from my database and plot something on a graph. However, I'm struggling to plot multiple datasets on the same chart. My database consists of 4 columns: id,data_type, value, sent_on (=string representing date and time). As I have 4 different data types, what I'm trying to do is to plot a line graph for every data type on a single chart. On the x-axis the date&time (sent_on column) and on the y-axis the values. My html file is as follows: var ctx = document.getElementById('myChart').getContext('2d'); var myChart = new Chart(ctx, { type: 'line', data: { labels: [{% for item in qs %}'{{item.sent_on}}',{% endfor %}], datasets: [{ label: 'Battery', data: [{% for item in qs %}{% if item.data_type == 'BT' %}{{item.message}}{% endif %},{% endfor %}], fill: false, backgroundColor: 'rgba(153,255,51,0.4)', borderColor: 'rgba(153,255,51,0.4)', borderWidth: 1 }, { label: 'Tire pressure', data: [{% for item in qs %}{% if item.data_type == 'TP' %}{{item.message}}{% endif %},{% endfor %}], fill: false, backgroundColor: 'rgba(255, 0, 0, 1)', borderColor: 'rgba(255, 0, 0, 1)', borderWidth: 1 }] }, And the chart … -

Django Rest Framework + React JWT authentication, 403 Forbidden on protected views
I'm trying to make a CRUD website with DRF + react, i've somewhat followed this tutorial for authentication https://hackernoon.com/110percent-complete-jwt-authentication-with-django-and-react-2020-iejq34ta (with some differences since i'm using DRF and React completely separatedly) authentication is fine, i can already login, logout and signup, however any view that requires the permission "IsAuthenticated" gets me a 403 Forbidden, i've tried to also get the data through postman using the headers: Accept : application/json Authorization : JWT "myaccesstoken" but i also get a 403 with "detail": "You do not have permission to perform this action."

How to create an additional table to link the models?
There are two models Modules() and ParentCategory(). They are not linked in any way in the database. class Modules(models.Model): ..... class ParentCategory(models.Model): .... I want to make the connection between them on the following principle. One module contains several categories. Described this structure with a dictionary where dictionary key - module name and the value of the list of categories belonging to this module. pc_to_modules_assign = { "DTH": ['COMMON S2P', 'COMMON SOURCING', 'SERVICES', 'SOURCING'], "KLK": ['COMMON S2P', 'COMMON SOURCING', 'SERVICES', 'SXM'], "ODJU": ['COMMON S2P', 'SERVICES', 'Analytics'], "TD": ['COMMON S2P', 'SERVICES', 'CLM'], "MNH": ['COMMON S2P', 'SERVICES', 'eProcurement'], "OPI": ['COMMON S2P', 'SERVICES', 'I2P'], "AP": ['COMMON S2P', 'SERVICES', 'I2P', 'AP'], "DF": ['COMMON S2P', 'COMMON SOURCING', 'SERVICES', 'SOURCING', 'SXM', 'Analytics', 'CLM'], "CVB": ['COMMON S2P', 'SERVICES', 'eProcurement', 'I2P'], "GFT": ['COMMON S2P', 'COMMON SOURCING', 'SERVICES', 'SOURCING', 'SXM', 'Analytics', 'CLM', 'eProcurement', 'I2P'] } There is one primary category in the list. What kind of connections should be used in such a model or what fields are needed approximately. Something like that. class PCtoModules(models.Model): m = .....Modules pc = ....ParentCategory primary = models.BooleanField(default=False) But I'm confused as to what type of connection to apply. -

How do I define __str__() method in a model which has a Foreign Key of User model and get the values of fields in Django?
I have below model in my Django app and it has a Foreign Key of Django's default User Model with __str__() function. class Subject(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, max_length=100) subject = models.CharField(max_length=100) def __str__(self): return f'{self.user.username}' What I want to do is to show the subject name in the Admin Panel, when we open the Subjects Model/Table in the Admin Panel. Suppose that if we have a user with username 'khubi' and he has two subjects, then the Admin Panel just shows the username of the user that is 'khubi' instead of showing the subject's names. Below is the screenshot: I have tried to put this: return f'{self.user.username.subject}' But it gives the error that 'str' object has no attribute 'subject' and I have tried it as well: return f'{self.user.subject}' and it gives me the error 'User' object has no attribute 'subject' Can anyone guide me how will I get the name of the subject in the __str__() function and anywhere outside as well? Thanks in advanced. -

Display possible values (choices) of SlugRelatedField in drf-yasg OpenAPI and Swagger views
I have several models that I use as enums (basically, the model is just a name and a slug), like currencies and countries etc, and I'm trying to show the available choices in drf-yasg without success. My last attempt was adding this to the serializer's Meta class: swagger_schema_fields = { 'currency': {'enum': list(Currency.objects.values_list('slug', flat=True))} } But of course it failed miserably - not only it didn't show the enum values, it also broke the serializer (because it used the strings instead of the actual model). Is there any way of doing this? -

Django inheriting filtered query set to subclass
I have a base class which creates a query set, that is filtered by url parameters from a form. class MyListView(ListView): model = Foo limit = 1000 # Default limit def get_queryset(...): ... limit = self.request.GET.get('limit') ... object_list = model.objects.filter(q_objects).order_by(*o_by)[:limit] return object_list And I have another view for exporting the Listview class ExportCSVView(MyListView): template_name = 'export.csv' content_type = 'text/csv' My problem now is, that the Listview has a filtered query set (object_list), which works perfectly in the browser view, but the export view always exports the object_list based on the default parameters and not the ones from the url parameters. How can I get the export view to use the url parameter filtered object_list without implementing the complete get_queryset() functionality again? -

Database Design in django application representing a Graph: Multiple tables for Nodes or just one
I am running a django application with a postgresql database attached to it and I am not sure about my database implementation. I want to implement a graph with nodes and edges. Every node has specific coordinates and in the end I want to draw the graph onto a map. I will send about 10000 nodes in an API call, so data can increase quite quickly. I have three different type of nodes (let's call them Node1, Node2 and Node3). The nodes share some common properties but also have their own fields that they don't share with the other nodes. My question regarding the db is if in my use-case it is better to have one large table or if it is better to split this up into smaller tables. Option1: Create one big table with a type field for the specific node type in the model. The downside would be that this leaves many table cells empty when I create the nodes. class Node(models.Model): name = models.CharField(max_length=120, blank=True) graph = models.ForeignKey(Graph, on_delete=models.CASCADE) node_type = models.ChoiceField(....select type of Node...) custom-field-node1 = ... custom-field-node1 = ... custom-field-node2 = ... custom-field-node2 = ... custom-field-node3 = ... custom-field-node3 = ...
