How to Access Remote PostgreSQL Database Server Through VPN
I'm currently working with my office server, when i want to connect to the server, i have to use their VPN.

DRF - Authentication credentials were not provided. (Djoser + SimpleJWT)
I am currently getting an error when making a request to /users/me to receive back my user's data. From what I have been reading, I am not sending the token, though I'm not sure how to store it when I receive it from the jwt/create endpoint when signing in. This is from my Auth-Test/nuxt-auth/pages/index.vue file: onMounted(async () => { const cookie = useCookie('jwt'); console.log('COOKIE: ' + JSON.stringify(cookie)); const response = await fetch('http://localhost:8000/api/auth/users/me/', { headers: { 'Content-Type': 'application/json', 'Authorization': `JWT ${JSON.stringify(cookie)}`, }, credentials: 'include' }) const content = await response.json(); console.log(content); }) and this is from my Auth-Test/nuxt-auth/pages/login.vue const router = useRouter(); async function submit() { console.log(JSON.stringify({ email: user.email, password: user.password })) await fetch('http://localhost:8000/api/auth/jwt/create/', { method: 'POST', headers: { 'Content-Type': 'application/json' }, credentials: 'include', body: JSON.stringify({ email: user.email, password: user.password }) }); await router.push({ path: '/' }); } Could anyone help me realize what I might be (am) doing wrong? I can't seem to figure out it myself through the use of documentation after a lot of reading. In case you might need to access the other files (front and back end), here is the Github repo. -

Refrehing the Django model after save and 5 second sleep get me old state, what's wrong?
I was able to save the data to a Django model without any errors, but data not reflected in db. But after a sleep time I was able to save the data again with same method. What might be causing this ? I suspect use of the Google API, but was able to print the data before performing the save operation. def update_channel(): client = Client.objects.get(name="name") print(f"Existing channel: {data['id']}") # 123 # fetch channel data from google api data = google_drive.subscribe_new_channel() client.channel_id = data["id"] client.channel_resource_id = data["resourceId"] client.save() client.refresh_from_db() print(f"New channel: {data['id']}") # 456 print(f"New channel in db: {client.channel_id}") # 456 time.sleep(5) client.refresh_from_db() print(f"channel in db: {client.changes_channel_id}") # 123 -

django rest framework is removing "+" from datetimes
I have a simple django get view: @api_view(["GET"]) @permission_classes([IsAuthenticated]) def test_endpoint(request): print(request) print(request.GET) The result of this - <rest_framework.request.Request: GET '/api/test_endpoint?start=1969-12-31T19:00:00+05:00&end=2023-01-16T21:22:52-05:00'> <QueryDict: {'start': ['1969-12-31T19:00:00 05:00'], 'end': ['2023-01-16T21:22:52-05:00']}> If you notice start for some reason is cleansing out the + in the datetime. Thus causing an incorrectly formatted datetime object. I have no interest in changing my formatting, but rather fixing why django rest framework is removing the +. You can clearly see in the actual GET request that the + is properly in the string. Any ideas on how to fix this so start value would be '1969-12-31T19:00:00+05:00' instead of '1969-12-31T19:00:00 05:00' without "fixing" it after the fact? (I want the request.GET object to be correct, I don't want to fix the values after retrieving them from request.GET) -

Comment Mixin for Django. Why is CommentPost defined like this?
I am a beginner in Django, and I was reading WS Vincent's Django for beginners. In the second to last chapter, he writes the following code. He's creating a view that allows for comments that can handle GET and POST requests without mixing FormMixin and his created ArticleDetailView. I understand all of that, but what I don't understand is why it was constructed like this? Can someone explain what self.object and self.get_object are in this example? Also, why do we save twice in the second method? Thanks!: def post(self, request, *args, **kwargs): self.object = self.get_object() return super().post(request, *args, **kwargs) def form_valid(self, form): comment = form.save(commit=False) comment.article = self.object comment.save() return super().form_valid(form) def get_success_url(self): article = self.get_object() return reverse("article_detail", kwargs={"pk": article.pk}) -

Django - Adding a 2nd form to a page dynamically
I'm looking for guidance on creating a dynamic form in Django that changes depending on which participants are in a meeting. The background is as follows: The app is used to track meeting scores across several teams, each with 4-8 members. Over the course of a few days a team may have 6 meetings. For each meeting the Team will elect 1 or 2 members to be meeting Participants. Each meeting requires the team to put forward members such that over the course of the training all team members have participated in one or more meetings. For each meeting all other team members are "Observers". The challenge I'm facing is how to dynamically insert a form or form fields for each of the Observers given that the number of observers may be anything from none to 6. The idea is to allow Observers to "rate" the meeting and record this result in the Observer model. The ScoreCreate view correctly sets the 1st participant and populates the "Other Participant" dropdown with all other team members. HTMX in the template passes the 1st and if selected "other participant" to the observers function which is then able to sort out who the observers … -
How to create a "CHOICES" filter field from a model based on unique values from another model?
Good day! I would be very grateful for any help. I have two related tables - Django models. The field "nomer_kotl = models.TextField()" has an association with another model. And as "choices = CHOICES" I would like to have "unique" values from the "Nomerkotelnoy(models.Model)" model. How can I make the "choices = CHOICES" of the model (EmployeeModel(models.Model)) get the values from the field "nomer_kotl = models.TextField()" of the model (Nomerkotelnoy(models.Model)) ? When creating a form for selecting data from a model table for display in an application on a site. - I think how can I make the form have a choice in the form of "select dropdown" - the choice of only one value. class Nomerkotelnoy(models.Model): nomer_id = models.IntegerField(primary_key=True) nomer_kotl = models.TextField() def __str__(self): return self.nomer_kotl CHOICES = ( ("1", "1"), ("2", "2"), ("3", "3"), ("4", "4"), ("5", "5"), ("6", "6"), ("7", "7"), ("8", "8"), ) class EmployeeModel(models.Model): empid = models.IntegerField(primary_key=True) empname = models.CharField(max_length=50) salary = models.IntegerField() joindate = models.DateField() nomer_kotl = models.ForeignKey(Nomerkotelnoy, default=1, on_delete=models.CASCADE, choices = CHOICES) class Meta: db_table = "employee" -

Best GUI to run python [closed]
I am building an object detection tool using the Yolo algorithm(Which contains many dependencies). my python script works successfully. My question is, what would be the best GUI to implement with python? I am trying to build a commercial app that anyone on a windows computer can run without having to download python and all its dependencies. Here are some of the ideas that come to mind. Build a C# application form application and combine it with python with either ironpython or compile the python app into an exe and then fetch its output and display it on C# form. I can maybe create a Django web application. If you would have any suggestions from experience, I would be extremely grateful. -

How to autoescape form value in UpdateView in Django
I have a form where I use TinyMCE on textareas because I need my users have the option to style the text they enter. It works fine and saves the html codes to the model. I use the safe mode to show the values in the way the users entered it and it works fine but I have an UpdateView where the user can edit what was entered. My problem is that if the user uses the UpdateView to change whet he entered he see the html code in the UpdateView like below and I have no idea how to solve this. <h2>Text</h2> <b><p>More text</p></b> Can I autoescape off the form? I tried these methods but not worked: <div class="container"> <h2>Edit report</h2> <h5 class="my-3">You can edit your report here:</h5> {% autoescape off %} {{ form.as_p|safe }} <!-- tried it separately --> {% end autoescape %} <button type="submit" class="btn btn-warning my-3">Submit changes</button> -
How we can use model objects in ModelSerializer?
I have to create an endpoint to make a customer subscribes to a chef. The subscription model has two FK fields chef and customer.

Django return class attribute based on object status in database
I am new to django and trying to learn. Looking to see if there is a better way to produce the result wanted. See my example below: application_list.html - Table Data <td><span class="badge {% if app.application_status_id == 1 %} bg-secondary {% elif app.application_status_id == 2 %} bg-success ">{{ app.application_status }} </span> </td> See here I am setting the class based on the value of the application status id from the database. Instead of having multiple if statements, is it possible to place this code elsewhere to process and return the class attribute back to line? I have tried looking at views.py for the application, but unable to determine how this works. My thoughts were to create a function to return a context value for application_list. application/views.py def application_list(request): """List of all applications""" template = 'application/application_list.html' applications = Application.objects.all() context = { 'applications': applications, } return render(request, template, context) -

Why does my Django application using websocket not work when deployed?
